+<chapter id="cec-api">
+  <title>CEC: Consumer Electronics Control</title>
+
+  <section id="cec-intro">
+    <title>Introduction</title>
+    <para>
+      Note: this documents the proposed CEC API. This API is not yet finalized and
+      is currently only available as a staging kernel module.
+    </para>
+    <para>HDMI connectors provide a single pin for use by the Consumer Electronics
+    Control protocol. This protocol allows different devices connected by an HDMI cable
+    to communicate. The protocol for CEC version 1.4 is defined in supplements 1 (CEC)
+    and 2 (HEAC or HDMI Ethernet and Audio Return Channel) of the HDMI 1.4a
+    (<xref linkend="hdmi" />) specification and the extensions added to CEC version 2.0
+    are defined in chapter 11 of the HDMI 2.0 (<xref linkend="hdmi2" />) specification.
+    </para>
+
+    <para>The bitrate is very slow (effectively no more than 36 bytes per second) and
+    is based on the ancient AV.link protocol used in old SCART connectors. The protocol
+    closely resembles a crazy Rube Goldberg contraption and is an unholy mix of low and
+    high level messages. Some messages, especially those part of the HEAC protocol layered
+    on top of CEC, need to be handled by the kernel, others can be handled either by the
+    kernel or by userspace.</para>
+
+    <para>In addition, CEC can be implemented in HDMI receivers, transmitters and in USB
+    devices that have an HDMI input and an HDMI output and that control just the CEC pin.</para>
+
+    <para>Drivers that support CEC will create a CEC device node (/dev/cecX)
+    to give userspace access to the CEC adapter. The &CEC-ADAP-G-CAPS; ioctl will tell userspace
+    what it is allowed to do.</para>

+
+    <para>By default any filehandle can use &CEC-TRANSMIT; and &CEC-RECEIVE;, but
+in order to prevent applications from stepping on each others toes it must be possible
+to obtain exclusive access to the CEC adapter. This ioctl sets the filehandle
+to initiator and/or follower mode which can be exclusive depending on the chosen
+mode. The initiator is the filehandle that is used
+to initiate messages, i.e. it commands other CEC devices. The follower is the filehandle
+that receives messages sent to the CEC adapter and processes them. The same filehandle
+can be both initiator and follower, or this role can be taken by two different
+filehandles.</para>
+
+    <para>When a CEC message is received, then the CEC framework will decide how
+it will be processed. If the message is a reply to an earlier transmitted message,
+then the reply is sent back to the filehandle that is waiting for it. In addition
+the CEC framework will process it.</para>
+
+    <para>If the message is not a reply, then the CEC framework will process it
+first. If there is no follower, then the message is just discarded and a feature
+abort is sent back to the initiator if the framework couldn't process it. If there
+is a follower, then the message is passed on to the follower who will use
+&CEC-RECEIVE; to dequeue the new message. The framework expects the follower to
+make the right decisions.</para>
+
+    <para>The CEC framework will process core messages unless requested otherwise
+by the follower. The follower can enable the passthrough mode. In that case, the
+CEC framework will pass on most core messages without processing them and
+the follower will have to implement those messages. There are some messages
+that the core will always process, regardless of the passthrough mode. See
+<xref linkend="cec-core-processing" /> for details.</para>
+
+    <para>If there is no initiator, then any CEC filehandle can use &CEC-TRANSMIT;.
+If there is an exclusive initiator then only that initiator can call &CEC-TRANSMIT;.

+CEC Kernel Support
+==================
+
+The CEC framework provides a unified kernel interface for use with HDMI CEC
+hardware. It is designed to handle a multiple types of hardware (receivers,
+transmitters, USB dongles). The framework also gives the option to decide
+what to do in the kernel driver and what should be handled by userspace
+applications. In addition it integrates the remote control passthrough
+feature into the kernel's remote control framework.
+
+
+The CEC Protocol
+----------------
+
+The CEC protocol enables consumer electronic devices to communicate with each
+other through the HDMI connection. The protocol uses logical addresses in the
+communication. The logical address is strictly connected with the functionality
+provided by the device. The TV acting as the communication hub is always
+assigned address 0. The physical address is determined by the physical
+connection between devices.
+
+The CEC framework described here is up to date with the CEC 2.0 specification.
+It is documented in the HDMI 1.4 specification with the new 2.0 bits documented
+in the HDMI 2.0 specification. But for most of the features the freely available
+HDMI 1.3a specification is sufficient:
+
+http://www.microprocessor.org/HDMISpecification13a.pdf
+
+
+The Kernel Interface
+====================
+
+CEC Adapter
+-----------
+
+The struct cec_adapter represents the CEC adapter hardware. It is created by
+calling cec_allocate_adapter() and deleted by calling cec_delete_adapter():
+
+struct cec_adapter *cec_allocate_adapter(const struct cec_adap_ops *ops,
+	       void *priv, const char *name, u32 caps, u8 available_las,
+	       struct device *parent);
+void cec_delete_adapter(struct cec_adapter *adap);
+
+To create an adapter you need to pass the following information:
+
+ops: adapter operations which are called by the CEC framework and that you
+have to implement.
+
+priv: will be stored in adap->priv and can be used by the adapter ops.
+
+name: the name of the CEC adapter. Note: this name will be copied.
+
+caps: capabilities of the CEC adapter. These capabilities determine the
+	capabilities of the hardware and which parts are to be handled
+	by userspace and which parts are handled by kernelspace. The
+	capabilities are returned by CEC_ADAP_G_CAPS.
+
+available_las: the number of simultaneous logical addresses that this
+	adapter can handle. Must be 1 <= available_las <= CEC_MAX_LOG_ADDRS.
+
+parent: the parent device.
+
+
+To register the /dev/cecX device node and the remote control device (if
+CEC_CAP_RC is set) you call:
+
+int cec_register_adapter(struct cec_adapter *adap);
+
+To unregister the devices call:
+
+void cec_unregister_adapter(struct cec_adapter *adap);
+
+Note: if cec_register_adapter() fails, then call cec_delete_adapter() to
+clean up. But if cec_register_adapter() succeeded, then only call
+cec_unregister_adapter() to clean up, never cec_delete_adapter(). The
+unregister function will delete the adapter automatically once the last user
+of that /dev/cecX device has closed its file handle.
+
+
+Implementing the Low-Level CEC Adapter
+--------------------------------------
+
+The following low-level adapter operations have to be implemented in
+your driver:
+
+struct cec_adap_ops {
+	/* Low-level callbacks */
+	int (*adap_enable)(struct cec_adapter *adap, bool enable);
+	int (*adap_monitor_all_enable)(struct cec_adapter *adap, bool enable);
+	int (*adap_log_addr)(struct cec_adapter *adap, u8 logical_addr);
+	int (*adap_transmit)(struct cec_adapter *adap, u8 attempts,
+			     u32 signal_free_time, struct cec_msg *msg);
+	void (*adap_log_status)(struct cec_adapter *adap);
+
+	/* High-level callbacks */
+	...
+};
+
+The three low-level ops deal with various aspects of controlling the CEC adapter
+hardware:
+
+
+To enable/disable the hardware:
+
+	int (*adap_enable)(struct cec_adapter *adap, bool enable);
+
+This callback enables or disables the CEC hardware. Enabling the CEC hardware
+means powering it up in a state where no logical addresses are claimed. This
+op assumes that the physical address (adap->phys_addr) is valid when enable is
+true and will not change while the CEC adapter remains enabled. The initial
+state of the CEC adapter after calling cec_allocate_adapter() is disabled.
+
+Note that adap_enable must return 0 if enable is false.
+
+
+To enable/disable the 'monitor all' mode:
+
+	int (*adap_monitor_all_enable)(struct cec_adapter *adap, bool enable);
+
+If enabled, then the adapter should be put in a mode to also monitor messages
+that not for us. Not all hardware supports this and this function is only
+called if the CEC_CAP_MONITOR_ALL capability is set. This callback is optional
+(some hardware may always be in 'monitor all' mode).
+
+Note that adap_monitor_all_enable must return 0 if enable is false.
+
+
+To program a new logical address:
+
+	int (*adap_log_addr)(struct cec_adapter *adap, u8 logical_addr);
+
+If logical_addr == CEC_LOG_ADDR_INVALID then all programmed logical addresses
+are to be erased. Otherwise the given logical address should be programmed.
+If the maximum number of available logical addresses is exceeded, then it
+should return -ENXIO. Once a logical address is programmed the CEC hardware
+can receive directed messages to that address.
+
+Note that adap_log_addr must return 0 if logical_addr is CEC_LOG_ADDR_INVALID.
+
+
+To transmit a new message:
+
+	int (*adap_transmit)(struct cec_adapter *adap, u8 attempts,
+			     u32 signal_free_time, struct cec_msg *msg);
+
+This transmits a new message. The attempts argument is the suggested number of
+attempts for the transmit.
+
+The signal_free_time is the number of data bit periods that the adapter should
+wait when the line is free before attempting to send a message. This value
+depends on whether this transmit is a retry, a message from a new initiator or
+a new message for the same initiator. Most hardware will handle this
+automatically, but in some cases this information is needed.
+
+The CEC_FREE_TIME_TO_USEC macro can be used to convert signal_free_time to
+microseconds (one data bit period is 2.4 ms).
+
+
+To log the current CEC hardware status:
+
+	void (*adap_status)(struct cec_adapter *adap, struct seq_file *file);
+
+This optional callback can be used to show the status of the CEC hardware.
+The status is available through debugfs: cat /sys/kernel/debug/cec/cecX/status
+
+
+Your adapter driver will also have to react to events (typically interrupt
+driven) by calling into the framework in the following situations:
+
+When a transmit finished (successfully or otherwise):
+
+void cec_transmit_done(struct cec_adapter *adap, u8 status, u8 arb_lost_cnt,
+		       u8 nack_cnt, u8 low_drive_cnt, u8 error_cnt);
+
+The status can be one of:
+
+CEC_TX_STATUS_OK: the transmit was successful.
+CEC_TX_STATUS_ARB_LOST: arbitration was lost: another CEC initiator
+took control of the CEC line and you lost the arbitration.
+CEC_TX_STATUS_NACK: the message was nacked (for a directed message) or
+acked (for a broadcast message). A retransmission is needed.
+CEC_TX_STATUS_LOW_DRIVE: low drive was detected on the CEC bus. This
+indicates that a follower detected an error on the bus and requested a
+retransmission.
+CEC_TX_STATUS_ERROR: some unspecified error occurred: this can be one of
+the previous two if the hardware cannot differentiate or something else
+entirely.
+CEC_TX_STATUS_MAX_RETRIES: could not transmit the message after
+trying multiple times. Should only be set by the driver if it has hardware
+support for retrying messages. If set, then the framework assumes that it
+doesn't have to make another attempt to transmit the message since the
+hardware did that already.
+
+The *_cnt arguments are the number of error conditions that were seen.
+This may be 0 if no information is available. Drivers that do not support
+hardware retry can just set the counter corresponding to the transmit error
+to 1, if the hardware does support retry then either set these counters to
+0 if the hardware provides no feedback of which errors occurred and how many
+times, or fill in the correct values as reported by the hardware.
+
+When a CEC message was received:
+
+void cec_received_msg(struct cec_adapter *adap, struct cec_msg *msg);
+
+Speaks for itself.
+
+Implementing the High-Level CEC Adapter
+---------------------------------------
+
+The low-level operations drive the hardware, the high-level operations are
+CEC protocol driven. The following high-level callbacks are available:
+
+struct cec_adap_ops {
+	/* Low-level callbacks */
+	...
+
+	/* High-level CEC message callback */
+	int (*received)(struct cec_adapter *adap, struct cec_msg *msg);
+};
+
+The received() callback allows the driver to optionally handle a newly
+received CEC message
+
+	int (*received)(struct cec_adapter *adap, struct cec_msg *msg);
+
+If the driver wants to process a CEC message, then it can implement this
+callback. If it doesn't want to handle this message, then it should return
+-ENOMSG, otherwise the CEC framework assumes it processed this message and
+it will not no anything with it.
+
+
+CEC framework functions
+-----------------------
+
+CEC Adapter drivers can call the following CEC framework functions:
+
+int cec_transmit_msg(struct cec_adapter *adap, struct cec_msg *msg,
+		     bool block);
+
+Transmit a CEC message. If block is true, then wait until the message has been
+transmitted, otherwise just queue it and return.
+
+void cec_s_phys_addr(struct cec_adapter *adap, u16 phys_addr, bool block);
+
+Change the physical address. This function will set adap->phys_addr and
+send an event if it has changed. If cec_s_log_addrs() has been called and
+the physical address has become valid, then the CEC framework will start
+claiming the logical addresses. If block is true, then this function won't
+return until this process has finished.
+
+When the physical address is set to a valid value the CEC adapter will
+be enabled (see the adap_enable op). When it is set to CEC_PHYS_ADDR_INVALID,
+then the CEC adapter will be disabled. If you change a valid physical address
+to another valid physical address, then this function will first set the
+address to CEC_PHYS_ADDR_INVALID before enabling the new physical address.
+
+int cec_s_log_addrs(struct cec_adapter *adap,
+		    struct cec_log_addrs *log_addrs, bool block);
+
+Claim the CEC logical addresses. Should never be called if CEC_CAP_LOG_ADDRS
+is set. If block is true, then wait until the logical addresses have been
+claimed, otherwise just queue it and return. To unconfigure all logical
+addresses call this function with log_addrs set to NULL or with
+log_addrs->num_log_addrs set to 0. The block argument is ignored when
+unconfiguring. This function will just return if the physical address is
+invalid. Once the physical address becomes valid, then the framework will
+attempt to claim these logical addresses.

-Documentation for dvb-usb-framework module and its devices
-
-Idea behind the dvb-usb-framework
-=================================
-
-In March 2005 I got the new Twinhan USB2.0 DVB-T device. They provided specs and a firmware.
-
-Quite keen I wanted to put the driver (with some quirks of course) into dibusb.
-After reading some specs and doing some USB snooping, it realized, that the
-dibusb-driver would be a complete mess afterwards. So I decided to do it in a
-different way: With the help of a dvb-usb-framework.
-
-The framework provides generic functions (mostly kernel API calls), such as:
-
-- Transport Stream URB handling in conjunction with dvb-demux-feed-control
-  (bulk and isoc are supported)
-- registering the device for the DVB-API
-- registering an I2C-adapter if applicable
-- remote-control/input-device handling
-- firmware requesting and loading (currently just for the Cypress USB
-  controllers)
-- other functions/methods which can be shared by several drivers (such as
-  functions for bulk-control-commands)
-- TODO: a I2C-chunker. It creates device-specific chunks of register-accesses
-  depending on length of a register and the number of values that can be
-  multi-written and multi-read.
-
-The source code of the particular DVB USB devices does just the communication
-with the device via the bus. The connection between the DVB-API-functionality
-is done via callbacks, assigned in a static device-description (struct
-dvb_usb_device) each device-driver has to have.
-
-For an example have a look in drivers/media/usb/dvb-usb/vp7045*.
-
-Objective is to migrate all the usb-devices (dibusb, cinergyT2, maybe the
-ttusb; flexcop-usb already benefits from the generic flexcop-device) to use
-the dvb-usb-lib.
-
-TODO: dynamic enabling and disabling of the pid-filter in regard to number of
-feeds requested.
-
-Supported devices
-========================

-  2004-06-06 - first TS received, but kernel oops :/
-  2004-05-14 - firmware loader is working
-  2004-05-11 - start writing the driver
-
-1. How to use?
-1.1. Firmware
-
-Most of the USB drivers need to download a firmware to the device before start
-working.
-
-Have a look at the Wikipage for the DVB-USB-drivers to find out, which firmware
-you need for your device:
-
-https://linuxtv.org/wiki/index.php/DVB_USB
-
-1.2. Compiling
-
-Since the driver is in the linux kernel, activating the driver in
-your favorite config-environment should sufficient. I recommend
-to compile the driver as module. Hotplug does the rest.
-
-If you use dvb-kernel enter the build-2.6 directory run 'make' and 'insmod.sh
-load' afterwards.
-
-1.3. Loading the drivers
-
-Hotplug is able to load the driver, when it is needed (because you plugged
-in the device).
-
-If you want to enable debug output, you have to load the driver manually and
-from within the dvb-kernel cvs repository.
-
-first have a look, which debug level are available:
-
-modinfo dvb-usb
-modinfo dvb-usb-vp7045
-etc.
-
-modprobe dvb-usb debug=<level>
-modprobe dvb-usb-vp7045 debug=<level>
-etc.
-
-should do the trick.
-
-When the driver is loaded successfully, the firmware file was in
-the right place and the device is connected, the "Power"-LED should be
-turned on.
-
-At this point you should be able to start a dvb-capable application. I'm use
-(t|s)zap, mplayer and dvbscan to test the basics. VDR-xine provides the
-long-term test scenario.
-
-2. Known problems and bugs
-
-- Don't remove the USB device while running an DVB application, your system
-  will go crazy or die most likely.
-
-2.1. Adding support for devices
-
-TODO
-
-2.2. USB1.1 Bandwidth limitation
-
-A lot of the currently supported devices are USB1.1 and thus they have a
-maximum bandwidth of about 5-6 MBit/s when connected to a USB2.0 hub.
-This is not enough for receiving the complete transport stream of a
-DVB-T channel (which is about 16 MBit/s). Normally this is not a
-problem, if you only want to watch TV (this does not apply for HDTV),
-but watching a channel while recording another channel on the same
-frequency simply does not work very well. This applies to all USB1.1
-DVB-T devices, not just the dvb-usb-devices)
-
-The bug, where the TS is distorted by a heavy usage of the device is gone
-definitely. All dvb-usb-devices I was using (Twinhan, Kworld, DiBcom) are
-working like charm now with VDR. Sometimes I even was able to record a channel
-and watch another one.
-
-2.3. Comments
-
-Patches, comments and suggestions are very very welcome.
-

-HOWTO: Get An Avermedia DVB-T working under Linux
-	   ______________________________________________
-
-   Table of Contents
-   Assumptions and Introduction
-   The Avermedia DVB-T
-   Getting the card going
-   Receiving DVB-T in Australia
-   Known Limitations
-   Further Update
-
-Assumptions and Introduction
-
-   It  is assumed that the reader understands the basic structure
-   of  the Linux Kernel DVB drivers and the general principles of
-   Digital TV.
-
-   One  significant difference between Digital TV and Analogue TV
-   that  the  unwary  (like  myself)  should  consider  is  that,
-   although  the  component  structure  of budget DVB-T cards are
-   substantially  similar  to Analogue TV cards, they function in
-   substantially different ways.
-
-   The  purpose  of  an  Analogue TV is to receive and display an
-   Analogue  Television  signal. An Analogue TV signal (otherwise
-   known  as  composite  video)  is  an  analogue  encoding  of a
-   sequence  of  image frames (25 per second) rasterised using an
-   interlacing   technique.   Interlacing  takes  two  fields  to
-   represent  one  frame.  Computers today are at their best when
-   dealing  with  digital  signals,  not  analogue  signals and a
-   composite  video signal is about as far removed from a digital
-   data stream as you can get. Therefore, an Analogue TV card for
-   a PC has the following purpose:
-
-     * Tune the receiver to receive a broadcast signal
-     * demodulate the broadcast signal
-     * demultiplex  the  analogue video signal and analogue audio
-       signal  (note some countries employ a digital audio signal
-       embedded  within the modulated composite analogue signal -
-       NICAM.)
-     * digitize  the analogue video signal and make the resulting
-       datastream available to the data bus.
-
-   The  digital  datastream from an Analogue TV card is generated
-   by  circuitry on the card and is often presented uncompressed.
-   For  a PAL TV signal encoded at a resolution of 768x576 24-bit
-   color pixels over 25 frames per second - a fair amount of data
-   is  generated and must be processed by the PC before it can be
-   displayed  on the video monitor screen. Some Analogue TV cards
-   for  PCs  have  onboard  MPEG2  encoders  which permit the raw
-   digital  data  stream  to be presented to the PC in an encoded
-   and  compressed  form  -  similar  to the form that is used in
-   Digital TV.
-
-   The  purpose of a simple budget digital TV card (DVB-T,C or S)
-   is to simply:
-
-     * Tune the received to receive a broadcast signal.
-     * Extract  the encoded digital datastream from the broadcast
-       signal.
-     * Make  the  encoded digital datastream (MPEG2) available to
-       the data bus.
-
-   The  significant  difference between the two is that the tuner
-   on  the analogue TV card spits out an Analogue signal, whereas
-   the  tuner  on  the  digital  TV  card  spits out a compressed
-   encoded   digital   datastream.   As  the  signal  is  already
-   digitised,  it  is  trivial  to pass this datastream to the PC
-   databus  with  minimal  additional processing and then extract
-   the  digital  video  and audio datastreams passing them to the
-   appropriate software or hardware for decoding and viewing.

-The Avermedia DVB-T
-
-   The Avermedia DVB-T is a budget PCI DVB card. It has 3 inputs:
-
-     * RF Tuner Input
-     * Composite Video Input (RCA Jack)
-     * SVIDEO Input (Mini-DIN)
-
-   The  RF  Tuner  Input  is the input to the tuner module of the
-   card.  The  Tuner  is  otherwise known as the "Frontend" . The
-   Frontend of the Avermedia DVB-T is a Microtune 7202D. A timely
-   post  to  the  linux-dvb  mailing  list  ascertained  that the
-   Microtune  7202D  is  supported  by the sp887x driver which is
-   found in the dvb-hw CVS module.
-
-   The  DVB-T card is based around the BT878 chip which is a very
-   common multimedia bridge and often found on Analogue TV cards.
-   There is no on-board MPEG2 decoder, which means that all MPEG2
-   decoding  must  be done in software, or if you have one, on an
-   MPEG2 hardware decoding card or chipset.
-     _________________________________________________________
-
-Getting the card going
-
-   In order to fire up the card, it is necessary to load a number
-   of modules from the DVB driver set. Prior to this it will have
-   been  necessary to download these drivers from the linuxtv CVS
-   server and compile them successfully.
-
-   Depending on the card's feature set, the Device Driver API for
-   DVB under Linux will expose some of the following device files
-   in the /dev tree:
-
-     * /dev/dvb/adapter0/audio0
-     * /dev/dvb/adapter0/ca0
-     * /dev/dvb/adapter0/demux0
-     * /dev/dvb/adapter0/dvr0
-     * /dev/dvb/adapter0/frontend0
-     * /dev/dvb/adapter0/net0
-     * /dev/dvb/adapter0/osd0
-     * /dev/dvb/adapter0/video0
-
-   The  primary  device  nodes that we are interested in (at this
-   stage) for the Avermedia DVB-T are:
-
-     * /dev/dvb/adapter0/dvr0
-     * /dev/dvb/adapter0/frontend0
-
-   The dvr0 device node is used to read the MPEG2 Data Stream and
-   the frontend0 node is used to tune the frontend tuner module.
-
-   At  this  stage,  it  has  not  been  able  to  ascertain  the
-   functionality  of the remaining device nodes in respect of the
-   Avermedia  DVBT.  However,  full  functionality  in respect of
-   tuning,  receiving  and  supplying  the  MPEG2  data stream is
-   possible  with the currently available versions of the driver.
-   It  may be possible that additional functionality is available
-   from  the  card  (i.e.  viewing the additional analogue inputs
-   that  the card presents), but this has not been tested yet. If
-   I get around to this, I'll update the document with whatever I
-   find.
-
-   To  power  up  the  card,  load  the  following modules in the
-   following order:
-
-     * modprobe bttv (normally loaded automatically)
-     * modprobe dvb-bt8xx (or place dvb-bt8xx in /etc/modules)
-
-   Insertion  of  these  modules  into  the  running  kernel will
-   activate the appropriate DVB device nodes. It is then possible
-   to start accessing the card with utilities such as scan, tzap,
-   dvbstream etc.
-
-   The frontend module sp887x.o, requires an external   firmware.
-   Please use  the  command "get_dvb_firmware sp887x" to download
-   it. Then copy it to /usr/lib/hotplug/firmware or /lib/firmware/
-   (depending on configuration of firmware hotplug).
-
-Receiving DVB-T in Australia
-
-   I  have  no  experience of DVB-T in other countries other than
-   Australia,  so  I will attempt to explain how it works here in
-   Melbourne  and how this affects the configuration of the DVB-T
-   card.
-
-   The  Digital  Broadcasting  Australia  website has a Reception
-   locatortool which provides information on transponder channels
-   and  frequencies.  My  local  transmitter  happens to be Mount
-   Dandenong.
-
-   The frequencies broadcast by Mount Dandenong are:
-
-   Table 1. Transponder Frequencies Mount Dandenong, Vic, Aus.
-   Broadcaster Channel Frequency
-   ABC         VHF 12  226.5 MHz
-   TEN         VHF 11  219.5 MHz
-   NINE        VHF 8   191.625 MHz
-   SEVEN       VHF 6   177.5 MHz
-   SBS         UHF 29  536.5 MHz
-
-   The Scan utility has a set of compiled-in defaults for various
-   countries and regions, but if they do not suit, or if you have
-   a pre-compiled scan binary, you can specify a data file on the
-   command  line which contains the transponder frequencies. Here
-   is a sample file for the above channel transponders:
-# Data file for DVB scan program
-#
-# C Frequency SymbolRate FEC QAM
-# S Frequency Polarisation SymbolRate FEC
-# T Frequency Bandwidth FEC FEC2 QAM Mode Guard Hier
-T 226500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-T 191625000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-T 219500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-T 177500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-T 536500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
-
-   The   defaults   for   the  transponder  frequency  and  other
-   modulation parameters were obtained from www.dba.org.au.
-
-   When  Scan  runs, it will output channels.conf information for
-   any  channel's transponders which the card's frontend can lock
-   onto.  (i.e.  any  whose  signal  is  strong  enough  at  your
-   antenna).
-
-   Here's my channels.conf file for anyone who's interested:

-Known Limitations
-
-   At  present  I can say with confidence that the frontend tunes
-   via /dev/dvb/adapter{x}/frontend0 and supplies an MPEG2 stream
-   via   /dev/dvb/adapter{x}/dvr0.   I   have   not   tested  the
-   functionality  of any other part of the card yet. I will do so
-   over time and update this document.
-
-   There  are some limitations in the i2c layer due to a returned
-   error message inconsistency. Although this generates errors in
-   dmesg  and  the  system logs, it does not appear to affect the
-   ability of the frontend to function correctly.
-     _________________________________________________________
-
-Further Update
-
-   dvbstream  and  VideoLAN  Client on windows works a treat with
-   DVB,  in  fact  this  is  currently  serving as my main way of
-   viewing  DVB-T  at  the  moment.  Additionally, VLC is happily
-   decoding  HDTV  signals,  although  the PC is dropping the odd
-   frame here and there - I assume due to processing capability -
-   as all the decoding is being done under windows in software.
-
-   Many  thanks to Nigel Pearson for the updates to this document
-   since the recent revision of the driver.

-How to get the bt8xx cards working
-==================================
-
-1) General information
-======================
-
-This class of cards has a bt878a as the PCI interface, and require the bttv driver
-for accessing the i2c bus and the gpio pins of the bt8xx chipset.
-Please see Documentation/dvb/cards.txt => o Cards based on the Conexant Bt8xx PCI bridge:
-
-Compiling kernel please enable:
-a.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "Enable Video for Linux API 1 (DEPRECATED)"
-b.)"Device drivers" => "Multimedia devices" => "Video For Linux" => "Video Capture Adapters" => "BT848 Video For Linux"
-c.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices" => "DVB for Linux" "DVB Core Support" "Bt8xx based PCI Cards"
-
-Please use the following options with care as deselection of drivers which are in fact necessary
-may result in DVB devices that cannot be tuned due to lack of driver support:
-You can save RAM by deselecting every frontend module that your DVB card does not need.
-
-First please remove the static dependency of DVB card drivers on all frontend modules for all possible card variants by enabling:
-d.) "Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
- => "DVB for Linux" "DVB Core Support" "Load and attach frontend modules as needed"
-
-If you know the frontend driver that your card needs please enable:
-e.)"Device drivers" => "Multimedia devices" => "Digital Video Broadcasting Devices"
- => "DVB for Linux" "DVB Core Support" "Customise DVB Frontends" => "Customise the frontend modules to build"
- Then please select your card-specific frontend module.
-
-2) Loading Modules
-==================
-
-Regular case: If the bttv driver detects a bt8xx-based DVB card, all frontend and backend modules will be loaded automatically.
-Exceptions are:
-- Old TwinHan DST cards or clones with or without CA slot and not containing an Eeprom.
-People running udev please see Documentation/dvb/udev.txt.
-
-In the following cases overriding the PCI type detection for dvb-bt8xx might be necessary:
-
-2a) Running TwinHan and Clones
-------------------------------
-
-	$ modprobe bttv card=113
-	$ modprobe dst
-
-Useful parameters for verbosity level and debugging the dst module:
-
-verbose=0:		messages are disabled
-	1:		only error messages are displayed
-	2:		notifications are displayed
-	3:		other useful messages are displayed
-	4:		debug setting
-dst_addons=0:		card is a free to air (FTA) card only
-	   0x20:	card has a conditional access slot for scrambled channels
-
-The autodetected values are determined by the cards' "response string".
-In your logs see f. ex.: dst_get_device_id: Recognize [DSTMCI].
-For bug reports please send in a complete log with verbose=4 activated.
-Please also see Documentation/dvb/ci.txt.
-
-2b) Running multiple cards
---------------------------
-
-Examples of card ID's:
-
-Pinnacle PCTV Sat:		 94
-Nebula Electronics Digi TV:	104
-pcHDTV HD-2000 TV:		112
-Twinhan DST and clones:		113
-Avermedia AverTV DVB-T 771:	123
-Avermedia AverTV DVB-T 761:	124
-DViCO FusionHDTV DVB-T Lite:	128
-DViCO FusionHDTV 5 Lite:	135
-
-Notice: The order of the card ID should be uprising:
-Example:
-	$ modprobe bttv card=113 card=135
-
-For a full list of card ID's please see Documentation/video4linux/CARDLIST.bttv.
-In case of further problems please subscribe and send questions to the mailing list: linux-dvb@linuxtv.org.
-
-2c) Probing the cards with broken PCI subsystem ID
---------------------------------------------------
-There are some TwinHan cards that the EEPROM has become corrupted for some
-reason. The cards do not have correct PCI subsystem ID. But we can force
-probing the cards with broken PCI subsystem ID
-
-	$ echo 109e 0878 $subvendor $subdevice > \

-How to set up the Technisat/B2C2 Flexcop devices
-================================================
-
-1) Find out what device you have
-================================
-
-Important Notice: The driver does NOT support Technisat USB 2 devices!
-
-First start your linux box with a shipped kernel:
-lspci -vvv for a PCI device (lsusb -vvv for an USB device) will show you for example:
-02:0b.0 Network controller: Techsan Electronics Co Ltd B2C2 FlexCopII DVB chip /
- Technisat SkyStar2 DVB card (rev 02)
-
-dmesg | grep frontend may show you for example:
-DVB: registering frontend 0 (Conexant CX24123/CX24109)...
-
-2) Kernel compilation:
-======================
-
-If the Flexcop / Technisat is the only DVB / TV / Radio device in your box
- get rid of unnecessary modules and check this one:
-"Multimedia support" => "Customise analog and hybrid tuner modules to build"
-In this directory uncheck every driver which is activated there
- (except "Simple tuner support" for ATSC 3rd generation only -> see case 9 please).
-
-Then please activate:
-2a) Main module part:
-"Multimedia support" => "DVB/ATSC adapters"
- => "Technisat/B2C2 FlexcopII(b) and FlexCopIII adapters"
-
-a.) => "Technisat/B2C2 Air/Sky/Cable2PC PCI" (PCI card) or
-b.) => "Technisat/B2C2 Air/Sky/Cable2PC USB" (USB 1.1 adapter)
- and for troubleshooting purposes:
-c.) => "Enable debug for the B2C2 FlexCop drivers"
-
-2b) Frontend / Tuner / Demodulator module part:
-"Multimedia support" => "DVB/ATSC adapters"
- => "Customise the frontend modules to build" "Customise DVB frontends" =>
-
-1.) SkyStar DVB-S Revision 2.3:
-a.) => "Zarlink VP310/MT312/ZL10313 based"
-b.) => "Generic I2C PLL based tuners"
-
-2.) SkyStar DVB-S Revision 2.6:
-a.) => "ST STV0299 based"
-b.) => "Generic I2C PLL based tuners"
-
-3.) SkyStar DVB-S Revision 2.7:
-a.) => "Samsung S5H1420 based"
-b.) => "Integrant ITD1000 Zero IF tuner for DVB-S/DSS"
-c.) => "ISL6421 SEC controller"
-
-4.) SkyStar DVB-S Revision 2.8:
-a.) => "Conexant CX24123 based"
-b.) => "Conexant CX24113/CX24128 tuner for DVB-S/DSS"
-c.) => "ISL6421 SEC controller"
-
-5.) AirStar DVB-T card:
-a.) => "Zarlink MT352 based"
-b.) => "Generic I2C PLL based tuners"
-
-6.) CableStar DVB-C card:
-a.) => "ST STV0297 based"
-b.) => "Generic I2C PLL based tuners"
-
-7.) AirStar ATSC card 1st generation:
-a.) => "Broadcom BCM3510"
-
-8.) AirStar ATSC card 2nd generation:
-a.) => "NxtWave Communications NXT2002/NXT2004 based"
-b.) => "Generic I2C PLL based tuners"
-
-9.) AirStar ATSC card 3rd generation:
-a.) => "LG Electronics LGDT3302/LGDT3303 based"
-b.) "Multimedia support" => "Customise analog and hybrid tuner modules to build"
- => "Simple tuner support"

+HOWTO: Get An Avermedia DVB-T working under Linux
+-------------------------------------------------
+
+February 14th 2006
+
+.. note::
+
+   This documentation is outdated. Please check at the DVB wiki
+   at https://linuxtv.org/wiki for more updated info.
+
+   There's a section there specific for Avermedia boards at:
+   https://linuxtv.org/wiki/index.php/AVerMedia
+
+
+Assumptions and Introduction
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+It  is assumed that the reader understands the basic structure
+of  the Linux Kernel DVB drivers and the general principles of
+Digital TV.
+
+One  significant difference between Digital TV and Analogue TV
+that  the  unwary  (like  myself)  should  consider  is  that,
+although  the  component  structure  of budget DVB-T cards are
+substantially  similar  to Analogue TV cards, they function in
+substantially different ways.
+
+The  purpose  of  an  Analogue TV is to receive and display an
+Analogue  Television  signal. An Analogue TV signal (otherwise
+known  as  composite  video)  is  an  analogue  encoding  of a
+sequence  of  image frames (25 per second) rasterised using an
+interlacing   technique.   Interlacing  takes  two  fields  to
+represent  one  frame.  Computers today are at their best when
+dealing  with  digital  signals,  not  analogue  signals and a
+composite  video signal is about as far removed from a digital
+data stream as you can get. Therefore, an Analogue TV card for
+a PC has the following purpose:
+
+* Tune the receiver to receive a broadcast signal
+* demodulate the broadcast signal
+* demultiplex  the  analogue video signal and analogue audio
+  signal. **NOTE:** some countries employ a digital audio signal
+  embedded  within the modulated composite analogue signal -
+  NICAM.)
+* digitize  the analogue video signal and make the resulting
+  datastream available to the data bus.
+
+The  digital  datastream from an Analogue TV card is generated
+by  circuitry on the card and is often presented uncompressed.
+For  a PAL TV signal encoded at a resolution of 768x576 24-bit
+color pixels over 25 frames per second - a fair amount of data
+is  generated and must be processed by the PC before it can be
+displayed  on the video monitor screen. Some Analogue TV cards
+for  PCs  have  onboard  MPEG2  encoders  which permit the raw
+digital  data  stream  to be presented to the PC in an encoded
+and  compressed  form  -  similar  to the form that is used in
+Digital TV.
+
+The  purpose of a simple budget digital TV card (DVB-T,C or S)
+is to simply:
+
+* Tune the received to receive a broadcast signal.
+* Extract  the encoded digital datastream from the broadcast
+  signal.
+* Make  the  encoded digital datastream (MPEG2) available to
+  the data bus.
+
+The  significant  difference between the two is that the tuner
+on  the analogue TV card spits out an Analogue signal, whereas
+the  tuner  on  the  digital  TV  card  spits out a compressed
+encoded   digital   datastream.   As  the  signal  is  already
+digitised,  it  is  trivial  to pass this datastream to the PC
+databus  with  minimal  additional processing and then extract
+the  digital  video  and audio datastreams passing them to the
+appropriate software or hardware for decoding and viewing.
+
+The Avermedia DVB-T
+~~~~~~~~~~~~~~~~~~~
+
+The Avermedia DVB-T is a budget PCI DVB card. It has 3 inputs:
+
+* RF Tuner Input
+* Composite Video Input (RCA Jack)
+* SVIDEO Input (Mini-DIN)
+
+The  RF  Tuner  Input  is the input to the tuner module of the
+card.  The  Tuner  is  otherwise known as the "Frontend" . The
+Frontend of the Avermedia DVB-T is a Microtune 7202D. A timely
+post  to  the  linux-dvb  mailing  list  ascertained  that the
+Microtune  7202D  is  supported  by the sp887x driver which is
+found in the dvb-hw CVS module.
+
+The  DVB-T card is based around the BT878 chip which is a very
+common multimedia bridge and often found on Analogue TV cards.
+There is no on-board MPEG2 decoder, which means that all MPEG2
+decoding  must  be done in software, or if you have one, on an
+MPEG2 hardware decoding card or chipset.
+
+
+Getting the card going
+~~~~~~~~~~~~~~~~~~~~~~
+
+In order to fire up the card, it is necessary to load a number
+of modules from the DVB driver set. Prior to this it will have
+been  necessary to download these drivers from the linuxtv CVS
+server and compile them successfully.
+
+Depending on the card's feature set, the Device Driver API for
+DVB under Linux will expose some of the following device files
+in the /dev tree:
+
+* /dev/dvb/adapter0/audio0
+* /dev/dvb/adapter0/ca0
+* /dev/dvb/adapter0/demux0
+* /dev/dvb/adapter0/dvr0
+* /dev/dvb/adapter0/frontend0
+* /dev/dvb/adapter0/net0
+* /dev/dvb/adapter0/osd0
+* /dev/dvb/adapter0/video0
+
+The  primary  device  nodes that we are interested in (at this
+stage) for the Avermedia DVB-T are:
+
+* /dev/dvb/adapter0/dvr0
+* /dev/dvb/adapter0/frontend0
+
+The dvr0 device node is used to read the MPEG2 Data Stream and
+the frontend0 node is used to tune the frontend tuner module.
+
+At  this  stage,  it  has  not  been  able  to  ascertain  the
+functionality  of the remaining device nodes in respect of the
+Avermedia  DVBT.  However,  full  functionality  in respect of
+tuning,  receiving  and  supplying  the  MPEG2  data stream is
+possible  with the currently available versions of the driver.
+It  may be possible that additional functionality is available
+from  the  card  (i.e.  viewing the additional analogue inputs
+that  the card presents), but this has not been tested yet. If
+I get around to this, I'll update the document with whatever I
+find.
+
+To  power  up  the  card,  load  the  following modules in the
+following order:
+
+* modprobe bttv (normally loaded automatically)
+* modprobe dvb-bt8xx (or place dvb-bt8xx in /etc/modules)
+
+Insertion  of  these  modules  into  the  running  kernel will
+activate the appropriate DVB device nodes. It is then possible
+to start accessing the card with utilities such as scan, tzap,
+dvbstream etc.
+
+The frontend module sp887x.o, requires an external   firmware.
+Please use  the  command "get_dvb_firmware sp887x" to download
+it. Then copy it to /usr/lib/hotplug/firmware or /lib/firmware/
+(depending on configuration of firmware hotplug).
+
+Receiving DVB-T in Australia
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+I  have  no  experience of DVB-T in other countries other than
+Australia,  so  I will attempt to explain how it works here in
+Melbourne  and how this affects the configuration of the DVB-T
+card.
+
+The  Digital  Broadcasting  Australia  website has a Reception
+locatortool which provides information on transponder channels
+and  frequencies.  My  local  transmitter  happens to be Mount
+Dandenong.
+
+The frequencies broadcast by Mount Dandenong are:
+
+Table 1. Transponder Frequencies Mount Dandenong, Vic, Aus.
+Broadcaster Channel Frequency
+ABC         VHF 12  226.5 MHz
+TEN         VHF 11  219.5 MHz
+NINE        VHF 8   191.625 MHz
+SEVEN       VHF 6   177.5 MHz
+SBS         UHF 29  536.5 MHz
+
+The Scan utility has a set of compiled-in defaults for various
+countries and regions, but if they do not suit, or if you have
+a pre-compiled scan binary, you can specify a data file on the
+command  line which contains the transponder frequencies. Here
+is a sample file for the above channel transponders:
+
+::
+
+	# Data file for DVB scan program
+	#
+	# C Frequency SymbolRate FEC QAM
+	# S Frequency Polarisation SymbolRate FEC
+	# T Frequency Bandwidth FEC FEC2 QAM Mode Guard Hier
+	T 226500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
+	T 191625000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
+	T 219500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
+	T 177500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
+	T 536500000 7MHz 2/3 NONE QAM64 8k 1/8 NONE
+
+The   defaults   for   the  transponder  frequency  and  other
+modulation parameters were obtained from www.dba.org.au.
+
+When  Scan  runs, it will output channels.conf information for
+any  channel's transponders which the card's frontend can lock
+onto.  (i.e.  any  whose  signal  is  strong  enough  at  your
+antenna).
+
+Here's my channels.conf file for anyone who's interested:

+Known Limitations
+~~~~~~~~~~~~~~~~~
+
+At  present  I can say with confidence that the frontend tunes
+via /dev/dvb/adapter{x}/frontend0 and supplies an MPEG2 stream
+via   /dev/dvb/adapter{x}/dvr0.   I   have   not   tested  the
+functionality  of any other part of the card yet. I will do so
+over time and update this document.
+
+There  are some limitations in the i2c layer due to a returned
+error message inconsistency. Although this generates errors in
+dmesg  and  the  system logs, it does not appear to affect the
+ability of the frontend to function correctly.
+
+Further Update
+~~~~~~~~~~~~~~
+
+dvbstream  and  VideoLAN  Client on windows works a treat with
+DVB,  in  fact  this  is  currently  serving as my main way of
+viewing  DVB-T  at  the  moment.  Additionally, VLC is happily
+decoding  HDTV  signals,  although  the PC is dropping the odd
+frame here and there - I assume due to processing capability -
+as all the decoding is being done under windows in software.
+
+Many  thanks to Nigel Pearson for the updates to this document
+since the recent revision of the driver.

+How to get the bt8xx cards working
+==================================
+
+Authors: Richard Walker,
+	 Jamie Honan,
+	 Michael Hunold,
+	 Manu Abraham,
+	 Uwe Bugla,
+	 Michael Krufky
+
+.. note::
+
+   This documentation is outdated. Please check at the DVB wiki
+   at https://linuxtv.org/wiki for more updated info.
+
+General information
+-------------------
+
+This class of cards has a bt878a as the PCI interface, and require the bttv driver
+for accessing the i2c bus and the gpio pins of the bt8xx chipset.
+Please see Documentation/dvb/cards.txt => o Cards based on the Conexant Bt8xx PCI bridge:
+
+Compiling kernel please enable:
+
+#) ``Device drivers`` => ``Multimedia devices`` => ``Video For Linux`` => ``Enable Video for Linux API 1 (DEPRECATED)``
+#) ``Device drivers`` => ``Multimedia devices`` => ``Video For Linux`` => ``Video Capture Adapters`` => ``BT848 Video For Linux``
+#) ``Device drivers`` => ``Multimedia devices`` => ``Digital Video Broadcasting Devices`` => ``DVB for Linux`` ``DVB Core Support`` ``Bt8xx based PCI Cards``
+
+  Please use the following options with care as deselection of drivers which are in fact necessary may result in DVB devices that cannot be tuned due to lack of driver support:
+  You can save RAM by deselecting every frontend module that your DVB card does not need.
+
+  First please remove the static dependency of DVB card drivers on all frontend modules for all possible card variants by enabling:
+
+#) ``Device drivers`` => ``Multimedia devices`` => ``Digital Video Broadcasting Devices`` => ``DVB for Linux`` ``DVB Core Support`` ``Load and attach frontend modules as needed``
+
+  If you know the frontend driver that your card needs please enable:
+
+#) ``Device drivers`` => ``Multimedia devices`` => ``Digital Video Broadcasting Devices`` => ``DVB for Linux`` ``DVB Core Support`` ``Customise DVB Frontends`` => ``Customise the frontend modules to build``
+
+ Then please select your card-specific frontend module.
+
+Loading Modules
+---------------
+
+Regular case: If the bttv driver detects a bt8xx-based DVB card, all frontend and backend modules will be loaded automatically.
+Exceptions are:
+- Old TwinHan DST cards or clones with or without CA slot and not containing an Eeprom.
+People running udev please see Documentation/dvb/udev.txt.
+
+In the following cases overriding the PCI type detection for dvb-bt8xx might be necessary:
+
+Running TwinHan and Clones
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+.. code-block:: none
+
+	$ modprobe bttv card=113
+	$ modprobe dst
+
+Useful parameters for verbosity level and debugging the dst module:
+
+.. code-block:: none
+
+	verbose=0:		messages are disabled
+		1:		only error messages are displayed
+		2:		notifications are displayed
+		3:		other useful messages are displayed
+		4:		debug setting
+	dst_addons=0:		card is a free to air (FTA) card only
+		0x20:	card has a conditional access slot for scrambled channels
+
+The autodetected values are determined by the cards' "response string".
+In your logs see f. ex.: dst_get_device_id: Recognize [DSTMCI].
+For bug reports please send in a complete log with verbose=4 activated.
+Please also see Documentation/dvb/ci.txt.
+
+Running multiple cards
+~~~~~~~~~~~~~~~~~~~~~~
+
+Examples of card ID's:
+
+.. code-block:: none
+
+	Pinnacle PCTV Sat:		 94
+	Nebula Electronics Digi TV:	104
+	pcHDTV HD-2000 TV:		112
+	Twinhan DST and clones:		113
+	Avermedia AverTV DVB-T 771:	123
+	Avermedia AverTV DVB-T 761:	124
+	DViCO FusionHDTV DVB-T Lite:	128
+	DViCO FusionHDTV 5 Lite:	135
+
+.. note::
+
+   The order of the card ID should be uprising:
+
+   Example:
+
+   .. code-block:: none
+
+	$ modprobe bttv card=113 card=135
+
+For a full list of card ID's please see Documentation/video4linux/CARDLIST.bttv.
+In case of further problems please subscribe and send questions to the mailing list: linux-dvb@linuxtv.org.
+
+Probing the cards with broken PCI subsystem ID
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+There are some TwinHan cards that the EEPROM has become corrupted for some
+reason. The cards do not have correct PCI subsystem ID. But we can force
+probing the cards with broken PCI subsystem ID
+
+.. code-block:: none
+
+	$ echo 109e 0878 $subvendor $subdevice > \
+		/sys/bus/pci/drivers/bt878/new_id
+
+.. code-block:: none
+
+	109e: PCI_VENDOR_ID_BROOKTREE

+Idea behind the dvb-usb-framework
+=================================
+
+.. note::
+
+   #) This documentation is outdated. Please check at the DVB wiki
+      at https://linuxtv.org/wiki for more updated info.
+
+   #) **deprecated:** Newer DVB USB drivers should use the dvb-usb-v2 framework.
+
+In March 2005 I got the new Twinhan USB2.0 DVB-T device. They provided specs
+and a firmware.
+
+Quite keen I wanted to put the driver (with some quirks of course) into dibusb.
+After reading some specs and doing some USB snooping, it realized, that the
+dibusb-driver would be a complete mess afterwards. So I decided to do it in a
+different way: With the help of a dvb-usb-framework.
+
+The framework provides generic functions (mostly kernel API calls), such as:
+
+- Transport Stream URB handling in conjunction with dvb-demux-feed-control
+  (bulk and isoc are supported)
+- registering the device for the DVB-API
+- registering an I2C-adapter if applicable
+- remote-control/input-device handling
+- firmware requesting and loading (currently just for the Cypress USB
+  controllers)
+- other functions/methods which can be shared by several drivers (such as
+  functions for bulk-control-commands)
+- TODO: a I2C-chunker. It creates device-specific chunks of register-accesses
+  depending on length of a register and the number of values that can be
+  multi-written and multi-read.
+
+The source code of the particular DVB USB devices does just the communication
+with the device via the bus. The connection between the DVB-API-functionality
+is done via callbacks, assigned in a static device-description (struct
+dvb_usb_device) each device-driver has to have.
+
+For an example have a look in drivers/media/usb/dvb-usb/vp7045*.
+
+Objective is to migrate all the usb-devices (dibusb, cinergyT2, maybe the
+ttusb; flexcop-usb already benefits from the generic flexcop-device) to use
+the dvb-usb-lib.
+
+TODO: dynamic enabling and disabling of the pid-filter in regard to number of
+feeds requested.

+
+  - start writing the driver
+
+How to use?
+-----------
+
+Firmware
+~~~~~~~~
+
+Most of the USB drivers need to download a firmware to the device before start
+working.
+
+Have a look at the Wikipage for the DVB-USB-drivers to find out, which firmware
+you need for your device:
+
+https://linuxtv.org/wiki/index.php/DVB_USB
+
+Compiling
+~~~~~~~~~
+
+Since the driver is in the linux kernel, activating the driver in
+your favorite config-environment should sufficient. I recommend
+to compile the driver as module. Hotplug does the rest.
+
+If you use dvb-kernel enter the build-2.6 directory run 'make' and 'insmod.sh
+load' afterwards.
+
+Loading the drivers
+~~~~~~~~~~~~~~~~~~~
+
+Hotplug is able to load the driver, when it is needed (because you plugged
+in the device).
+
+If you want to enable debug output, you have to load the driver manually and
+from within the dvb-kernel cvs repository.
+
+first have a look, which debug level are available:
+
+.. code-block:: none
+
+	# modinfo dvb-usb
+	# modinfo dvb-usb-vp7045
+
+	etc.
+
+.. code-block:: none
+
+	modprobe dvb-usb debug=<level>
+	modprobe dvb-usb-vp7045 debug=<level>
+	etc.
+
+should do the trick.
+
+When the driver is loaded successfully, the firmware file was in
+the right place and the device is connected, the "Power"-LED should be
+turned on.
+
+At this point you should be able to start a dvb-capable application. I'm use
+(t|s)zap, mplayer and dvbscan to test the basics. VDR-xine provides the
+long-term test scenario.
+
+Known problems and bugs
+-----------------------
+
+- Don't remove the USB device while running an DVB application, your system
+  will go crazy or die most likely.
+
+Adding support for devices
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+TODO
+
+USB1.1 Bandwidth limitation
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A lot of the currently supported devices are USB1.1 and thus they have a
+maximum bandwidth of about 5-6 MBit/s when connected to a USB2.0 hub.
+This is not enough for receiving the complete transport stream of a
+DVB-T channel (which is about 16 MBit/s). Normally this is not a
+problem, if you only want to watch TV (this does not apply for HDTV),
+but watching a channel while recording another channel on the same
+frequency simply does not work very well. This applies to all USB1.1
+DVB-T devices, not just the dvb-usb-devices)
+
+The bug, where the TS is distorted by a heavy usage of the device is gone
+definitely. All dvb-usb-devices I was using (Twinhan, Kworld, DiBcom) are
+working like charm now with VDR. Sometimes I even was able to record a channel
+and watch another one.
+
+Comments
+~~~~~~~~
+
+Patches, comments and suggestions are very very welcome.

+Introduction
+============
+
+This document covers the Linux Kernel to Userspace API's used by video
+and radio streaming devices, including video cameras, analog and digital
+TV receiver cards, AM/FM receiver cards, Software Defined Radio (SDR),
+streaming capture and output devices, codec devices and remote controllers.
+
+A typical media device hardware is shown at :ref:`typical_media_device`.

+    :alt:    typical_media_device.svg
+    :align:  center
+
+    Typical Media Device
+
+The media infrastructure API was designed to control such devices. It is
+divided into five parts.
+
+1. The :ref:`first part <v4l2spec>` covers radio, video capture and output,
+   cameras, analog TV devices and codecs.
+
+2. The :ref:`second part <dvbapi>` covers the API used for digital TV and
+   Internet reception via one of the several digital tv standards. While it is
+   called as DVB API, in fact it covers several different video standards
+   including DVB-T/T2, DVB-S/S2, DVB-C, ATSC, ISDB-T, ISDB-S, DTMB, etc. The
+   complete list of supported standards can be found at
+   :ref:`fe-delivery-system-t`.
+
+3. The :ref:`third part <remote_controllers>` covers the Remote Controller API.
+
+4. The :ref:`fourth part <media_controller>` covers the Media Controller API.
+
+5. The :ref:`fifth part <cec>` covers the CEC (Consumer Electronics Control) API.
+
+It should also be noted that a media device may also have audio components, like
+mixers, PCM capture, PCM playback, etc, which are controlled via ALSA API.  For
+additional information and for the latest development code, see:
+`https://linuxtv.org <https://linuxtv.org>`__.  For discussing improvements,
+reporting troubles, sending new drivers, etc, please mail to: `Linux Media
+Mailing List (LMML) <http://vger.kernel.org/vger-lists.html#linux-media>`__.

+
+Digital TV Frontend kABI
+------------------------
+
+Digital TV Frontend
+~~~~~~~~~~~~~~~~~~~
+
+The Digital TV Frontend kABI defines a driver-internal interface for
+registering low-level, hardware specific driver to a hardware independent
+frontend layer. It is only of interest for Digital TV device driver writers.
+The header file for this API is named dvb_frontend.h and located in
+drivers/media/dvb-core.
+
+Before using the Digital TV frontend core, the bridge driver should attach
+the frontend demod, tuner and SEC devices and call
+:cpp:func:`dvb_register_frontend()`,
+in order to register the new frontend at the subsystem. At device
+detach/removal, the bridge driver should call
+:cpp:func:`dvb_unregister_frontend()` to
+remove the frontend from the core and then :cpp:func:`dvb_frontend_detach()`
+to free the memory allocated by the frontend drivers.
+
+The drivers should also call :cpp:func:`dvb_frontend_suspend()` as part of
+their handler for the :c:type:`device_driver`.\ ``suspend()``, and
+:cpp:func:`dvb_frontend_resume()` as
+part of their handler for :c:type:`device_driver`.\ ``resume()``.
+
+A few other optional functions are provided to handle some special cases.
+
+.. kernel-doc:: drivers/media/dvb-core/dvb_frontend.h
+
+
+Digital TV Demux kABI
+---------------------
+
+Digital TV Demux
+~~~~~~~~~~~~~~~~
+
+The Kernel Digital TV Demux kABI defines a driver-internal interface for
+registering low-level, hardware specific driver to a hardware independent
+demux layer. It is only of interest for Digital TV device driver writers.
+The header file for this kABI is named demux.h and located in
+drivers/media/dvb-core.
+
+The demux kABI should be implemented for each demux in the system. It is
+used to select the TS source of a demux and to manage the demux resources.
+When the demux client allocates a resource via the demux kABI, it receives
+a pointer to the kABI of that resource.
+
+Each demux receives its TS input from a DVB front-end or from memory, as
+set via this demux kABI. In a system with more than one front-end, the kABI
+can be used to select one of the DVB front-ends as a TS source for a demux,
+unless this is fixed in the HW platform.
+
+The demux kABI only controls front-ends regarding to their connections with
+demuxes; the kABI used to set the other front-end parameters, such as
+tuning, are devined via the Digital TV Frontend kABI.
+
+The functions that implement the abstract interface demux should be defined
+static or module private and registered to the Demux core for external
+access. It is not necessary to implement every function in the struct
+&dmx_demux. For example, a demux interface might support Section filtering,
+but not PES filtering. The kABI client is expected to check the value of any
+function pointer before calling the function: the value of ``NULL`` means
+that the function is not available.
+
+Whenever the functions of the demux API modify shared data, the
+possibilities of lost update and race condition problems should be
+addressed, e.g. by protecting parts of code with mutexes.
+
+Note that functions called from a bottom half context must not sleep.
+Even a simple memory allocation without using ``GFP_ATOMIC`` can result in a
+kernel thread being put to sleep if swapping is needed. For example, the
+Linux Kernel calls the functions of a network device interface from a
+bottom half context. Thus, if a demux kABI function is called from network
+device code, the function must not sleep.
+
+
+
+Demux Callback API
+------------------
+
+Demux Callback
+~~~~~~~~~~~~~~
+
+This kernel-space API comprises the callback functions that deliver filtered
+data to the demux client. Unlike the other DVB kABIs, these functions are
+provided by the client and called from the demux code.
+
+The function pointers of this abstract interface are not packed into a
+structure as in the other demux APIs, because the callback functions are
+registered and used independent of each other. As an example, it is possible
+for the API client to provide several callback functions for receiving TS
+packets and no callbacks for PES packets or sections.
+
+The functions that implement the callback API need not be re-entrant: when
+a demux driver calls one of these functions, the driver is not allowed to
+call the function again before the original call returns. If a callback is
+triggered by a hardware interrupt, it is recommended to use the Linux
+bottom half mechanism or start a tasklet instead of making the callback
+function call directly from a hardware interrupt.
+
+This mechanism is implemented by :cpp:func:`dmx_ts_cb()` and :cpp:func:`dmx_section_cb()`
+callbacks.

+Media Controller devices
+------------------------
+
+Media Controller
+~~~~~~~~~~~~~~~~
+
+The media controller userspace API is documented in
+:ref:`the Media Controller uAPI book <media_common>`. This document focus
+on the kernel-side implementation of the media framework.
+
+Abstract media device model
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Discovering a device internal topology, and configuring it at runtime, is one
+of the goals of the media framework. To achieve this, hardware devices are
+modelled as an oriented graph of building blocks called entities connected
+through pads.
+
+An entity is a basic media hardware building block. It can correspond to
+a large variety of logical blocks such as physical hardware devices
+(CMOS sensor for instance), logical hardware devices (a building block
+in a System-on-Chip image processing pipeline), DMA channels or physical
+connectors.
+
+A pad is a connection endpoint through which an entity can interact with
+other entities. Data (not restricted to video) produced by an entity
+flows from the entity's output to one or more entity inputs. Pads should
+not be confused with physical pins at chip boundaries.
+
+A link is a point-to-point oriented connection between two pads, either
+on the same entity or on different entities. Data flows from a source
+pad to a sink pad.
+
+Media device
+^^^^^^^^^^^^
+
+A media device is represented by a :c:type:`struct media_device <media_device>`
+instance, defined in ``include/media/media-device.h``.
+Allocation of the structure is handled by the media device driver, usually by
+embedding the :c:type:`media_device` instance in a larger driver-specific
+structure.
+
+Drivers register media device instances by calling
+:cpp:func:`__media_device_register()` via the macro ``media_device_register()``
+and unregistered by calling :cpp:func:`media_device_unregister()`.
+
+Entities
+^^^^^^^^
+
+Entities are represented by a :c:type:`struct media_entity <media_entity>`
+instance, defined in ``include/media/media-entity.h``. The structure is usually
+embedded into a higher-level structure, such as
+:ref:`v4l2_subdev` or :ref:`video_device`
+instances, although drivers can allocate entities directly.
+
+Drivers initialize entity pads by calling
+:cpp:func:`media_entity_pads_init()`.
+
+Drivers register entities with a media device by calling
+:cpp:func:`media_device_register_entity()`
+and unregistred by calling
+:cpp:func:`media_device_unregister_entity()`.
+
+Interfaces
+^^^^^^^^^^
+
+Interfaces are represented by a
+:c:type:`struct media_interface <media_interface>` instance, defined in
+``include/media/media-entity.h``. Currently, only one type of interface is
+defined: a device node. Such interfaces are represented by a
+:c:type:`struct media_intf_devnode <media_intf_devnode>`.
+
+Drivers initialize and create device node interfaces by calling
+:cpp:func:`media_devnode_create()`
+and remove them by calling:
+:cpp:func:`media_devnode_remove()`.
+
+Pads
+^^^^
+Pads are represented by a :c:type:`struct media_pad <media_pad>` instance,
+defined in ``include/media/media-entity.h``. Each entity stores its pads in
+a pads array managed by the entity driver. Drivers usually embed the array in
+a driver-specific structure.
+
+Pads are identified by their entity and their 0-based index in the pads
+array.
+
+Both information are stored in the :c:type:`struct media_pad`, making the
+:c:type:`media_pad` pointer the canonical way to store and pass link references.
+
+Pads have flags that describe the pad capabilities and state.
+
+``MEDIA_PAD_FL_SINK`` indicates that the pad supports sinking data.
+``MEDIA_PAD_FL_SOURCE`` indicates that the pad supports sourcing data.
+
+.. note::
+
+  One and only one of ``MEDIA_PAD_FL_SINK`` or ``MEDIA_PAD_FL_SOURCE`` must
+  be set for each pad.
+
+Links
+^^^^^
+
+Links are represented by a :c:type:`struct media_link <media_link>` instance,
+defined in ``include/media/media-entity.h``. There are two types of links:
+
+**1. pad to pad links**:
+
+Associate two entities via their PADs. Each entity has a list that points
+to all links originating at or targeting any of its pads.
+A given link is thus stored twice, once in the source entity and once in
+the target entity.
+
+Drivers create pad to pad links by calling:
+:cpp:func:`media_create_pad_link()` and remove with
+:cpp:func:`media_entity_remove_links()`.
+
+**2. interface to entity links**:
+
+Associate one interface to a Link.
+
+Drivers create interface to entity links by calling:
+:cpp:func:`media_create_intf_link()` and remove with
+:cpp:func:`media_remove_intf_links()`.
+
+.. note::
+
+   Links can only be created after having both ends already created.
+
+Links have flags that describe the link capabilities and state. The
+valid values are described at :cpp:func:`media_create_pad_link()` and
+:cpp:func:`media_create_intf_link()`.
+
+Graph traversal
+^^^^^^^^^^^^^^^
+
+The media framework provides APIs to iterate over entities in a graph.
+
+To iterate over all entities belonging to a media device, drivers can use
+the media_device_for_each_entity macro, defined in
+``include/media/media-device.h``.
+
+..  code-block:: c
+
+    struct media_entity *entity;
+
+    media_device_for_each_entity(entity, mdev) {
+    // entity will point to each entity in turn
+    ...
+    }
+
+Drivers might also need to iterate over all entities in a graph that can be
+reached only through enabled links starting at a given entity. The media
+framework provides a depth-first graph traversal API for that purpose.
+
+.. note::
+
+   Graphs with cycles (whether directed or undirected) are **NOT**
+   supported by the graph traversal API. To prevent infinite loops, the graph
+   traversal code limits the maximum depth to ``MEDIA_ENTITY_ENUM_MAX_DEPTH``,
+   currently defined as 16.
+
+Drivers initiate a graph traversal by calling
+:cpp:func:`media_entity_graph_walk_start()`
+
+The graph structure, provided by the caller, is initialized to start graph
+traversal at the given entity.
+
+Drivers can then retrieve the next entity by calling
+:cpp:func:`media_entity_graph_walk_next()`
+
+When the graph traversal is complete the function will return ``NULL``.
+
+Graph traversal can be interrupted at any moment. No cleanup function call
+is required and the graph structure can be freed normally.
+
+Helper functions can be used to find a link between two given pads, or a pad
+connected to another pad through an enabled link
+:cpp:func:`media_entity_find_link()` and
+:cpp:func:`media_entity_remote_pad()`.
+
+Use count and power handling
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Due to the wide differences between drivers regarding power management
+needs, the media controller does not implement power management. However,
+the :c:type:`struct media_entity <media_entity>` includes a ``use_count``
+field that media drivers
+can use to track the number of users of every entity for power management
+needs.
+
+The :c:type:`media_entity<media_entity>`.\ ``use_count`` field is owned by
+media drivers and must not be
+touched by entity drivers. Access to the field must be protected by the
+:c:type:`media_device`.\ ``graph_mutex`` lock.
+
+Links setup
+^^^^^^^^^^^
+
+Link properties can be modified at runtime by calling
+:cpp:func:`media_entity_setup_link()`.
+
+Pipelines and media streams
+^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+When starting streaming, drivers must notify all entities in the pipeline to
+prevent link states from being modified during streaming by calling
+:cpp:func:`media_entity_pipeline_start()`.
+
+The function will mark all entities connected to the given entity through
+enabled links, either directly or indirectly, as streaming.
+
+The :c:type:`struct media_pipeline <media_pipeline>` instance pointed to by
+the pipe argument will be stored in every entity in the pipeline.
+Drivers should embed the :c:type:`struct media_pipeline <media_pipeline>`
+in higher-level pipeline structures and can then access the
+pipeline through the :c:type:`struct media_entity <media_entity>`
+pipe field.
+
+Calls to :cpp:func:`media_entity_pipeline_start()` can be nested.
+The pipeline pointer must be identical for all nested calls to the function.
+
+:cpp:func:`media_entity_pipeline_start()` may return an error. In that case,
+it will clean up any of the changes it did by itself.
+
+When stopping the stream, drivers must notify the entities with
+:cpp:func:`media_entity_pipeline_stop()`.
+
+If multiple calls to :cpp:func:`media_entity_pipeline_start()` have been
+made the same number of :cpp:func:`media_entity_pipeline_stop()` calls
+are required to stop streaming.
+The :c:type:`media_entity`.\ ``pipe`` field is reset to ``NULL`` on the last
+nested stop call.
+
+Link configuration will fail with ``-EBUSY`` by default if either end of the
+link is a streaming entity. Links that can be modified while streaming must
+be marked with the ``MEDIA_LNK_FL_DYNAMIC`` flag.
+
+If other operations need to be disallowed on streaming entities (such as
+changing entities configuration parameters) drivers can explicitly check the
+media_entity stream_count field to find out if an entity is streaming. This
+operation must be done with the media_device graph_mutex held.
+
+Link validation
+^^^^^^^^^^^^^^^
+
+Link validation is performed by :cpp:func:`media_entity_pipeline_start()`
+for any entity which has sink pads in the pipeline. The
+:c:type:`media_entity`.\ ``link_validate()`` callback is used for that
+purpose. In ``link_validate()`` callback, entity driver should check
+that the properties of the source pad of the connected entity and its own
+sink pad match. It is up to the type of the entity (and in the end, the
+properties of the hardware) what matching actually means.
+
+Subsystems should facilitate link validation by providing subsystem specific
+helper functions to provide easy access for commonly needed information, and
+in the end provide a way to use driver-specific callbacks.

+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``request``
+    CEC ioctl request code as defined in the cec.h header file, for
+    example :ref:`CEC_ADAP_G_CAPS`.
+

+    Pointer to a request-specific structure.
+
+
+Description
+===========
+
+.. note:: This documents the proposed CEC API. This API is not yet finalized
+   and is currently only available as a staging kernel module.
+
+The :c:func:`ioctl()` function manipulates cec device parameters. The
+argument ``fd`` must be an open file descriptor.
+
+The ioctl ``request`` code specifies the cec function to be called. It
+has encoded in it whether the argument is an input, output or read/write
+parameter, and the size of the argument ``argp`` in bytes.
+
+Macros and structures definitions specifying cec ioctl requests and
+their parameters are located in the cec.h header file. All cec ioctl
+requests, their respective function and parameters are specified in
+:ref:`cec-user-func`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+Request-specific error codes are listed in the individual requests
+descriptions.
+
+When an ioctl that takes an output or read/write parameter fails, the
+parameter remains unmodified.

+
+With the :c:func:`poll()` function applications can wait for CEC
+events.
+
+On success :c:func:`poll()` returns the number of file descriptors
+that have been selected (that is, file descriptors for which the
+``revents`` field of the respective :c:type:`struct pollfd` structure
+is non-zero). CEC devices set the ``POLLIN`` and ``POLLRDNORM`` flags in
+the ``revents`` field if there are messages in the receive queue. If the
+transmit queue has room for new messages, the ``POLLOUT`` and
+``POLLWRNORM`` flags are set. If there are events in the event queue,
+then the ``POLLPRI`` flag is set. When the function timed out it returns
+a value of zero, on failure it returns -1 and the ``errno`` variable is
+set appropriately.
+
+For more details see the :c:func:`poll()` manual page.
+
+
+Return Value
+============
+
+On success, :c:func:`poll()` returns the number structures which have
+non-zero ``revents`` fields, or zero if the call timed out. On error -1
+is returned, and the ``errno`` variable is set appropriately:
+
+``EBADF``
+    One or more of the ``ufds`` members specify an invalid file
+    descriptor.
+
+``EFAULT``
+    ``ufds`` references an inaccessible memory area.
+
+``EINTR``
+    The call was interrupted by a signal.
+
+``EINVAL``

+Introduction
+============
+
+.. note:: This documents the proposed CEC API. This API is not yet finalized
+   and is currently only available as a staging kernel module.
+
+HDMI connectors provide a single pin for use by the Consumer Electronics
+Control protocol. This protocol allows different devices connected by an
+HDMI cable to communicate. The protocol for CEC version 1.4 is defined
+in supplements 1 (CEC) and 2 (HEAC or HDMI Ethernet and Audio Return
+Channel) of the HDMI 1.4a (:ref:`hdmi`) specification and the
+extensions added to CEC version 2.0 are defined in chapter 11 of the
+HDMI 2.0 (:ref:`hdmi2`) specification.
+
+The bitrate is very slow (effectively no more than 36 bytes per second)
+and is based on the ancient AV.link protocol used in old SCART
+connectors. The protocol closely resembles a crazy Rube Goldberg
+contraption and is an unholy mix of low and high level messages. Some
+messages, especially those part of the HEAC protocol layered on top of
+CEC, need to be handled by the kernel, others can be handled either by
+the kernel or by userspace.
+
+In addition, CEC can be implemented in HDMI receivers, transmitters and
+in USB devices that have an HDMI input and an HDMI output and that
+control just the CEC pin.
+
+Drivers that support CEC will create a CEC device node (/dev/cecX) to
+give userspace access to the CEC adapter. The
+:ref:`CEC_ADAP_G_CAPS` ioctl will tell userspace what it is allowed to do.

+Description

+
+.. note:: This documents the proposed CEC API. This API is not yet finalized
+   and is currently only available as a staging kernel module.
+
+To query the current CEC logical addresses, applications call
+:ref:`ioctl CEC_ADAP_G_LOG_ADDRS <CEC_ADAP_G_LOG_ADDRS>` with a pointer to a
+:c:type:`struct cec_log_addrs` where the driver stores the logical addresses.
+
+To set new logical addresses, applications fill in
+:c:type:`struct cec_log_addrs` and call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+with a pointer to this struct. The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+is only available if ``CEC_CAP_LOG_ADDRS`` is set (the ``ENOTTY`` error code is
+returned otherwise). The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+can only be called by a file descriptor in initiator mode (see :ref:`CEC_S_MODE`), if not
+the ``EBUSY`` error code will be returned.
+
+To clear existing logical addresses set ``num_log_addrs`` to 0. All other fields
+will be ignored in that case. The adapter will go to the unconfigured state.
+
+If the physical address is valid (see :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>`),

+
+
+Description
+===========
+
+.. note:: This documents the proposed CEC API. This API is not yet finalized
+   and is currently only available as a staging kernel module.
+
+To query the current physical address applications call
+:ref:`ioctl CEC_ADAP_G_PHYS_ADDR <CEC_ADAP_G_PHYS_ADDR>` with a pointer to a __u16 where the
+driver stores the physical address.
+
+To set a new physical address applications store the physical address in
+a __u16 and call :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` with a pointer to
+this integer. The :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` is only available if
+``CEC_CAP_PHYS_ADDR`` is set (the ``ENOTTY`` error code will be returned
+otherwise). The :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>` can only be called
+by a file descriptor in initiator mode (see :ref:`CEC_S_MODE`), if not
+the ``EBUSY`` error code will be returned.
+
+To clear an existing physical address use ``CEC_PHYS_ADDR_INVALID``.
+The adapter will go to the unconfigured state.
+
+If logical address types have been defined (see :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`),
+then this ioctl will block until all
+requested logical addresses have been claimed. If the file descriptor is in non-blocking mode
+then it will not wait for the logical addresses to be claimed, instead it just returns 0.
+
+A :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` event is sent when the physical address
+changes.
+
+The physical address is a 16-bit number where each group of 4 bits
+represent a digit of the physical address a.b.c.d where the most
+significant 4 bits represent 'a'. The CEC root device (usually the TV)
+has address 0.0.0.0. Every device that is hooked up to an input of the
+TV has address a.0.0.0 (where 'a' is ≥ 1), devices hooked up to those in
+turn have addresses a.b.0.0, etc. So a topology of up to 5 devices deep
+is supported. The physical address a device shall use is stored in the
+EDID of the sink.
+
+For example, the EDID for each HDMI input of the TV will have a
+different physical address of the form a.0.0.0 that the sources will
+read out and use as their physical address.
+
+
+Return Value

+
+On success 0 is returned, on error -1 and the ``errno`` variable is set

+Description
+===========
+
+.. note:: This documents the proposed CEC API. This API is not yet finalized
+   and is currently only available as a staging kernel module.
+
+CEC devices can send asynchronous events. These can be retrieved by
+calling :ref:`ioctl CEC_DQEVENT <CEC_DQEVENT>`. If the file descriptor is in
+non-blocking mode and no event is pending, then it will return -1 and
+set errno to the ``EAGAIN`` error code.
+
+The internal event queues are per-filehandle and per-event type. If
+there is no more room in a queue then the last event is overwritten with
+the new one. This means that intermediate results can be thrown away but
+that the latest event is always available. This also means that is it
+possible to read two successive events that have the same value (e.g.
+two :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` events with
+the same state). In that case the intermediate state changes were lost but
+it is guaranteed that the state did change in between the two events.

+    CEC_G_MODE, CEC_S_MODE
+

+
+
+Description
+===========
+
+.. note:: This documents the proposed CEC API. This API is not yet finalized
+   and is currently only available as a staging kernel module.
+
+By default any filehandle can use :ref:`CEC_TRANSMIT`, but in order to prevent
+applications from stepping on each others toes it must be possible to
+obtain exclusive access to the CEC adapter. This ioctl sets the
+filehandle to initiator and/or follower mode which can be exclusive
+depending on the chosen mode. The initiator is the filehandle that is
+used to initiate messages, i.e. it commands other CEC devices. The
+follower is the filehandle that receives messages sent to the CEC
+adapter and processes them. The same filehandle can be both initiator
+and follower, or this role can be taken by two different filehandles.
+
+When a CEC message is received, then the CEC framework will decide how
+it will be processed. If the message is a reply to an earlier
+transmitted message, then the reply is sent back to the filehandle that
+is waiting for it. In addition the CEC framework will process it.
+
+If the message is not a reply, then the CEC framework will process it
+first. If there is no follower, then the message is just discarded and a
+feature abort is sent back to the initiator if the framework couldn't
+process it. If there is a follower, then the message is passed on to the
+follower who will use :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>` to dequeue
+the new message. The framework expects the follower to make the right
+decisions.
+
+The CEC framework will process core messages unless requested otherwise
+by the follower. The follower can enable the passthrough mode. In that
+case, the CEC framework will pass on most core messages without
+processing them and the follower will have to implement those messages.
+There are some messages that the core will always process, regardless of
+the passthrough mode. See :ref:`cec-core-processing` for details.
+
+If there is no initiator, then any CEC filehandle can use
+:ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`. If there is an exclusive
+initiator then only that initiator can call
+:ref:`CEC_TRANSMIT`. The follower can of course
+always call :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`.
+
+Available initiator modes are:

+
+       -  0x0
+
+       -  This is not an initiator, i.e. it cannot transmit CEC messages or
+	  make any other changes to the CEC adapter.
+
+    -  .. _`CEC-MODE-INITIATOR`:
+
+       -  ``CEC_MODE_INITIATOR``
+
+       -  0x1
+
+       -  This is an initiator (the default when the device is opened) and
+	  it can transmit CEC messages and make changes to the CEC adapter,
+	  unless there is an exclusive initiator.
+
+    -  .. _`CEC-MODE-EXCL-INITIATOR`:
+
+       -  ``CEC_MODE_EXCL_INITIATOR``
+
+       -  0x2
+
+       -  This is an exclusive initiator and this file descriptor is the
+	  only one that can transmit CEC messages and make changes to the
+	  CEC adapter. If someone else is already the exclusive initiator
+	  then an attempt to become one will return the ``EBUSY`` error code
+	  error.

+	  receive CEC messages for processing. If someone else is already
+	  the exclusive follower then an attempt to become one will return
+	  the ``EBUSY`` error code. You cannot become a follower if
+	  :ref:`CEC_CAP_TRANSMIT <CEC-CAP-TRANSMIT>` is not set or if :ref:`CEC_MODE_NO_INITIATOR <CEC-MODE-NO-INITIATOR>`

+
+       -  ``CEC_MODE_EXCL_FOLLOWER_PASSTHRU``
+
+       -  0x30
+
+       -  This is an exclusive follower and only this file descriptor will
+	  receive CEC messages for processing. In addition it will put the
+	  CEC device into passthrough mode, allowing the exclusive follower
+	  to handle most core messages instead of relying on the CEC
+	  framework for that. If someone else is already the exclusive
+	  follower then an attempt to become one will return the ``EBUSY`` error
+	  code. You cannot become a follower if :ref:`CEC_CAP_TRANSMIT <CEC-CAP-TRANSMIT>`
+	  is not set or if :ref:`CEC_MODE_NO_INITIATOR <CEC-MODE-NO-INITIATOR>` was specified,
+	  the ``EINVAL`` error code is returned in that case.

+    -  .. _`CEC-MODE-MONITOR`:
+
+       -  ``CEC_MODE_MONITOR``
+
+       -  0xe0
+
+       -  Put the file descriptor into monitor mode. Can only be used in
+	  combination with :ref:`CEC_MODE_NO_INITIATOR <CEC-MODE-NO-INITIATOR>`, otherwise EINVAL error
+	  code will be returned. In monitor mode all messages this CEC
+	  device transmits and all messages it receives (both broadcast
+	  messages and directed messages for one its logical addresses) will
+	  be reported. This is very useful for debugging. This is only
+	  allowed if the process has the ``CAP_NET_ADMIN`` capability. If
+	  that is not set, then the ``EPERM`` error code is returned.
+
+    -  .. _`CEC-MODE-MONITOR-ALL`:
+
+       -  ``CEC_MODE_MONITOR_ALL``
+
+       -  0xf0
+
+       -  Put the file descriptor into 'monitor all' mode. Can only be used
+	  in combination with :ref:`CEC_MODE_NO_INITIATOR <CEC-MODE-NO-INITIATOR>`, otherwise
+	  the ``EINVAL`` error code will be returned. In 'monitor all' mode all messages
+	  this CEC device transmits and all messages it receives, including
+	  directed messages for other CEC devices will be reported. This is
+	  very useful for debugging, but not all devices support this. This
+	  mode requires that the :ref:`CEC_CAP_MONITOR_ALL <CEC-CAP-MONITOR-ALL>` capability is set,
+	  otherwise the ``EINVAL`` error code is returned. This is only allowed if
+	  the process has the ``CAP_NET_ADMIN`` capability. If that is not

+Synopsis
+========

+.. cpp:function:: int ioctl( int fd, int request, struct cec_msg *argp )
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <cec-func-open>`.
+
+``request``
+    CEC_RECEIVE, CEC_TRANSMIT
+
+``argp``
+
+
+Description
+===========
+
+.. note:: This documents the proposed CEC API. This API is not yet finalized
+   and is currently only available as a staging kernel module.
+
+To receive a CEC message the application has to fill in the
+``timeout`` field of :c:type:`struct cec_msg` and pass it to :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+If the file descriptor is in non-blocking mode and there are no received
+messages pending, then it will return -1 and set errno to the ``EAGAIN``
+error code. If the file descriptor is in blocking mode and ``timeout``
+is non-zero and no message arrived within ``timeout`` milliseconds, then
+it will return -1 and set errno to the ``ETIMEDOUT`` error code.
+
+A received message can be:
+
+1. a message received from another CEC device (the ``sequence`` field will
+   be 0).
+2. the result of an earlier non-blocking transmit (the ``sequence`` field will
+   be non-zero).
+
+To send a CEC message the application has to fill in the
+:c:type:`struct cec_msg` and pass it to
+:ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`. The :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` is only available if
+``CEC_CAP_TRANSMIT`` is set. If there is no more room in the transmit
+queue, then it will return -1 and set errno to the ``EBUSY`` error code.
+The transmit queue has enough room for 18 messages (about 1 second worth
+of 2-byte messages). Note that the CEC kernel framework will also reply
+to core messages (see :ref:cec-core-processing), so it is not a good
+idea to fully fill up the transmit queue.
+
+If the file descriptor is in non-blocking mode then the transmit will
+return 0 and the result of the transmit will be available via
+:ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>` once the transmit has finished
+(including waiting for a reply, if requested).
+
+The ``sequence`` field is filled in for every transmit and this can be
+checked against the received messages to find the corresponding transmit
+result.

+
+    -  .. row 1
+
+       -  __u64
+
+       -  ``tx_ts``
+
+       -  Timestamp in ns of when the last byte of the message was transmitted.
+	  The timestamp has been taken from the ``CLOCK_MONOTONIC`` clock. To access
+	  the same clock from userspace use :c:func:`clock_gettime(2)`.
+
+    -  .. row 2
+

+
+       -  ``rx_ts``
+
+       -  Timestamp in ns of when the last byte of the message was received.

+
+    -  .. row 3
+
+       -  __u32
+
+       -  ``len``
+
+       -  The length of the message. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` this is filled in
+	  by the application. The driver will fill this in for
+	  :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` it will be
+	  filled in by the driver with the length of the reply message if ``reply`` was set.
+
+    -  .. row 4
+
+       -  __u32
+
+       -  ``timeout``
+
+       -  The timeout in milliseconds. This is the time the device will wait
+	  for a message to be received before timing out. If it is set to 0,
+	  then it will wait indefinitely when it is called by :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+	  If it is 0 and it is called by :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>`,
+	  then it will be replaced by 1000 if the ``reply`` is non-zero or
+	  ignored if ``reply`` is 0.
+
+    -  .. row 5
+
+       -  __u32
+
+       -  ``sequence``
+
+       -  A non-zero sequence number is automatically assigned by the CEC framework
+	  for all transmitted messages. It is used by the CEC framework when it queues
+	  the transmit result (when transmit was called in non-blocking mode). This
+	  allows the application to associate the received message with the original
+	  transmit.
+
+    -  .. row 6
+
+       -  __u32

+
+    -  .. row 7
+
+       -  __u8
+
+       -  ``tx_status``
+
+       -  The status bits of the transmitted message. See

+	  this messages was received, not transmitted.
+
+    -  .. row 8
+
+       -  __u8
+
+       -  ``msg[16]``
+
+       -  The message payload. For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` this is filled in by the
+	  application. The driver will fill this in for :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+	  For :ref:`ioctl CEC_TRANSMIT <CEC_TRANSMIT>` it will be filled in by the driver with
+	  the payload of the reply message if ``timeout`` was set.
+
+    -  .. row 8
+
+       -  __u8
+
+       -  ``reply``
+
+       -  Wait until this message is replied. If ``reply`` is 0 and the
+	  ``timeout`` is 0, then don't wait for a reply but return after
+	  transmitting the message. Ignored by :ref:`ioctl CEC_RECEIVE <CEC_RECEIVE>`.
+	  The case where ``reply`` is 0 (this is the opcode for the Feature Abort
+	  message) and ``timeout`` is non-zero is specifically allowed to make it
+	  possible to send a message and wait up to ``timeout`` milliseconds for a
+	  Feature Abort reply. In this case ``rx_status`` will either be set
+	  to :ref:`CEC_RX_STATUS_TIMEOUT <CEC-RX-STATUS-TIMEOUT>` or
+	  :ref:`CEC_RX_STATUS_FEATURE_ABORT <CEC-RX-STATUS-FEATURE-ABORT>`.
+

+
+       -  ``rx_status``
+
+       -  The status bits of the received message. See
+	  :ref:`cec-rx-status` for the possible status values. It is 0 if
+	  this message was transmitted, not received, unless this is the
+	  reply to a transmitted message. In that case both ``rx_status``

+Description
+-----------
+
+This system call opens a named audio device (e.g.
+/dev/dvb/adapter0/audio0) for subsequent use. When an open() call has
+succeeded, the device will be ready for use. The significance of
+blocking or non-blocking mode is described in the documentation for
+functions where there is a difference. It does not affect the semantics
+of the open() call itself. A device opened in blocking mode can later be
+put into non-blocking mode (and vice versa) using the F_SETFL command
+of the fcntl system call. This is a standard system call, documented in
+the Linux manual page for fcntl. Only one user can open the Audio Device
+in O_RDWR mode. All other attempts to open the device in this mode will
+fail, and an error code will be returned. If the Audio Device is opened
+in O_RDONLY mode, the only ioctl call that can be used is
+AUDIO_GET_STATUS. All other call will return with an error code.

+DVB Audio Device
+################
+The DVB audio device controls the MPEG2 audio decoder of the DVB
+hardware. It can be accessed through ``/dev/dvb/adapter?/audio?``. Data
+types and and ioctl definitions can be accessed by including
+``linux/dvb/audio.h`` in your application.
+
+Please note that some DVB cards don’t have their own MPEG decoder, which
+results in the omission of the audio and video device.
+
+These ioctls were also used by V4L2 to control MPEG decoders implemented
+in V4L2. The use of these ioctls for that purpose has been made obsolete
+and proper V4L2 ioctls or controls have been created to replace that
+functionality.

+Audio Data Types
+****************
+
+This section describes the structures, data types and defines used when
+talking to the audio device.
+
+
+.. _audio-stream-source-t:
+
+audio_stream_source_t
+=====================
+
+The audio stream source is set through the AUDIO_SELECT_SOURCE call
+and can take the following values, depending on whether we are replaying
+from an internal (demux) or external (user write) source.
+
+
+.. code-block:: c
+
+    typedef enum {
+	AUDIO_SOURCE_DEMUX,
+	AUDIO_SOURCE_MEMORY
+    } audio_stream_source_t;
+
+AUDIO_SOURCE_DEMUX selects the demultiplexer (fed either by the
+frontend or the DVR device) as the source of the video stream. If
+AUDIO_SOURCE_MEMORY is selected the stream comes from the application
+through the ``write()`` system call.
+
+
+.. _audio-play-state-t:
+
+audio_play_state_t
+==================
+
+The following values can be returned by the AUDIO_GET_STATUS call
+representing the state of audio playback.
+
+
+.. code-block:: c
+
+    typedef enum {
+	AUDIO_STOPPED,
+	AUDIO_PLAYING,
+	AUDIO_PAUSED
+    } audio_play_state_t;
+
+
+.. _audio-channel-select-t:
+
+audio_channel_select_t
+======================
+
+The audio channel selected via AUDIO_CHANNEL_SELECT is determined by
+the following values.
+
+
+.. code-block:: c
+
+    typedef enum {
+	AUDIO_STEREO,
+	AUDIO_MONO_LEFT,
+	AUDIO_MONO_RIGHT,
+	AUDIO_MONO,
+	AUDIO_STEREO_SWAPPED
+    } audio_channel_select_t;
+
+
+.. _audio-status:
+
+struct audio_status
+===================
+
+The AUDIO_GET_STATUS call returns the following structure informing
+about various states of the playback operation.
+
+
+.. code-block:: c
+

+following bits set according to the hardwares capabilities.
+
+
+.. code-block:: c
+
+     #define AUDIO_CAP_DTS    1

+    typedef
+    struct audio_karaoke {
+	int vocal1;
+	int vocal2;
+	int melody;
+    } audio_karaoke_t;
+
+If Vocal1 or Vocal2 are non-zero, they get mixed into left and right t
+at 70% each. If both, Vocal1 and Vocal2 are non-zero, Vocal1 gets mixed
+into the left channel and Vocal2 into the right channel at 100% each. Ff
+Melody is non-zero, the melody channel gets mixed into left and right.
+
+
+.. _audio-attributes-t:
+
+audio attributes
+================
+
+The following attributes can be set by a call to AUDIO_SET_ATTRIBUTES:
+
+
+.. code-block:: c
+
+     typedef uint16_t audio_attributes_t;
+     /*   bits: descr. */
+     /*   15-13 audio coding mode (0=ac3, 2=mpeg1, 3=mpeg2ext, 4=LPCM, 6=DTS, */

+
+
+Description
+-----------
+
+This system call opens a named ca device (e.g. /dev/ost/ca) for
+subsequent use.
+
+When an open() call has succeeded, the device will be ready for use. The
+significance of blocking or non-blocking mode is described in the
+documentation for functions where there is a difference. It does not
+affect the semantics of the open() call itself. A device opened in
+blocking mode can later be put into non-blocking mode (and vice versa)
+using the F_SETFL command of the fcntl system call. This is a standard
+system call, documented in the Linux manual page for fcntl. Only one
+user can open the CA Device in O_RDWR mode. All other attempts to open
+the device in this mode will fail, and an error code will be returned.

+Description
+-----------
+
+This system call, used with a device name of /dev/dvb/adapter0/demux0,
+allocates a new filter and returns a handle which can be used for
+subsequent control of that filter. This call has to be made for each
+filter to be used, i.e. every returned file descriptor is a reference to
+a single filter. /dev/dvb/adapter0/dvr0 is a logical device to be used
+for retrieving Transport Streams for digital video recording. When
+reading from this device a transport stream containing the packets from
+all PES filters set in the corresponding demux device
+(/dev/dvb/adapter0/demux0) having the output set to DMX_OUT_TS_TAP. A
+recorded Transport Stream is replayed by writing to this device.
+
+The significance of blocking or non-blocking mode is described in the
+documentation for functions where there is a difference. It does not
+affect the semantics of the open() call itself. A device opened in
+blocking mode can later be put into non-blocking mode (and vice versa)
+using the F_SETFL command of the fcntl system call.

+
+
+Description
+-----------
+
+This ioctl call returns the current value of the system time counter
+(which is driven by a PES filter of type DMX_PES_PCR). Some hardware
+supports more than one STC, so you must specify which one by setting the
+num field of stc before the ioctl (range 0...n). The result is returned
+in form of a ratio with a 64 bit numerator and a 32 bit denominator, so
+the real 90kHz STC value is stc->stc / stc->base .
+
+
+Return Value
+------------
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+Description
+-----------
+
+This ioctl call allows to remove a PID when multiple PIDs are set on a

+
+
+Description
+-----------
+
+This ioctl call sets up a filter according to the filter and mask
+parameters provided. A timeout may be defined stating number of seconds
+to wait for a section to be loaded. A value of 0 means that no timeout
+should be applied. Finally there is a flag field where it is possible to
+state whether a section should be CRC-checked, whether the filter should
+be a ”one-shot” filter, i.e. if the filtering operation should be
+stopped after the first section is received, and whether the filtering
+operation should be started immediately (without waiting for a
+DMX_START ioctl call). If a filter was previously set-up, this filter
+will be canceled, and the receive buffer will be flushed.
+

+Return Value

+
+On success 0 is returned, on error -1 and the ``errno`` variable is set

+.. _dvb-frontend-parameters:
+
+*******************
+frontend parameters
+*******************
+
+The kind of parameters passed to the frontend device for tuning depend
+on the kind of hardware you are using.
+
+The struct ``dvb_frontend_parameters`` uses an union with specific
+per-system parameters. However, as newer delivery systems required more
+data, the structure size weren't enough to fit, and just extending its
+size would break the existing applications. So, those parameters were
+replaced by the usage of
+:ref:`FE_GET_PROPERTY/FE_SET_PROPERTY <FE_GET_PROPERTY>`
+ioctl's. The new API is flexible enough to add new parameters to
+existing delivery systems, and to add newer delivery systems.
+
+So, newer applications should use
+:ref:`FE_GET_PROPERTY/FE_SET_PROPERTY <FE_GET_PROPERTY>`
+instead, in order to be able to support the newer System Delivery like
+DVB-S2, DVB-T2, DVB-C2, ISDB, etc.
+
+All kinds of parameters are combined as an union in the
+FrontendParameters structure:
+
+
+.. code-block:: c
+
+    struct dvb_frontend_parameters {
+	uint32_t frequency;     /* (absolute) frequency in Hz for QAM/OFDM */
+		    /* intermediate frequency in kHz for QPSK */
+	fe_spectral_inversion_t inversion;
+	union {
+	    struct dvb_qpsk_parameters qpsk;
+	    struct dvb_qam_parameters  qam;
+	    struct dvb_ofdm_parameters ofdm;
+	    struct dvb_vsb_parameters  vsb;
+	} u;
+    };
+
+In the case of QPSK frontends the ``frequency`` field specifies the
+intermediate frequency, i.e. the offset which is effectively added to
+the local oscillator frequency (LOF) of the LNB. The intermediate
+frequency has to be specified in units of kHz. For QAM and OFDM
+frontends the ``frequency`` specifies the absolute frequency and is
+given in Hz.
+
+
+.. _dvb-qpsk-parameters:
+
+QPSK parameters
+===============
+
+For satellite QPSK frontends you have to use the ``dvb_qpsk_parameters``
+structure:
+
+
+.. code-block:: c
+
+     struct dvb_qpsk_parameters {
+	 uint32_t        symbol_rate;  /* symbol rate in Symbols per second */
+	 fe_code_rate_t  fec_inner;    /* forward error correction (see above) */
+     };
+
+
+.. _dvb-qam-parameters:
+
+QAM parameters
+==============
+
+for cable QAM frontend you use the ``dvb_qam_parameters`` structure:
+
+
+.. code-block:: c
+
+     struct dvb_qam_parameters {
+	 uint32_t         symbol_rate; /* symbol rate in Symbols per second */
+	 fe_code_rate_t   fec_inner;   /* forward error correction (see above) */
+	 fe_modulation_t  modulation;  /* modulation type (see above) */
+     };
+
+
+.. _dvb-vsb-parameters:
+
+VSB parameters
+==============
+
+ATSC frontends are supported by the ``dvb_vsb_parameters`` structure:
+
+
+.. code-block:: c
+
+    struct dvb_vsb_parameters {
+	fe_modulation_t modulation; /* modulation type (see above) */
+    };
+
+
+.. _dvb-ofdm-parameters:
+
+OFDM parameters
+===============
+
+DVB-T frontends are supported by the ``dvb_ofdm_parameters`` structure:
+
+
+.. code-block:: c
+
+     struct dvb_ofdm_parameters {
+	 fe_bandwidth_t      bandwidth;
+	 fe_code_rate_t      code_rate_HP;  /* high priority stream code rate */
+	 fe_code_rate_t      code_rate_LP;  /* low priority stream code rate */
+	 fe_modulation_t     constellation; /* modulation type (see above) */
+	 fe_transmit_mode_t  transmission_mode;
+	 fe_guard_interval_t guard_interval;
+	 fe_hierarchy_t      hierarchy_information;
+     };

+DVB Frontend properties
+=======================
+
+Tuning into a Digital TV physical channel and starting decoding it
+requires changing a set of parameters, in order to control the tuner,
+the demodulator, the Linear Low-noise Amplifier (LNA) and to set the
+antenna subsystem via Satellite Equipment Control (SEC), on satellite
+systems. The actual parameters are specific to each particular digital
+TV standards, and may change as the digital TV specs evolves.
+
+In the past, the strategy used was to have a union with the parameters
+needed to tune for DVB-S, DVB-C, DVB-T and ATSC delivery systems grouped
+there. The problem is that, as the second generation standards appeared,
+those structs were not big enough to contain the additional parameters.
+Also, the union didn't have any space left to be expanded without
+breaking userspace. So, the decision was to deprecate the legacy
+union/struct based approach, in favor of a properties set approach.
+
+.. note:: On Linux DVB API version 3, setting a frontend were done via
+   :ref:`struct dvb_frontend_parameters <dvb-frontend-parameters>`.
+   This got replaced on version 5 (also called "S2API", as this API were
+   added originally_enabled to provide support for DVB-S2), because the
+   old API has a very limited support to new standards and new hardware.
+   This section describes the new and recommended way to set the frontend,
+   with suppports all digital TV delivery systems.
+
+Example: with the properties based approach, in order to set the tuner
+to a DVB-C channel at 651 kHz, modulated with 256-QAM, FEC 3/4 and
+symbol rate of 5.217 Mbauds, those properties should be sent to
+:ref:`FE_SET_PROPERTY <FE_GET_PROPERTY>` ioctl:
+
+-  :ref:`DTV_DELIVERY_SYSTEM <DTV-DELIVERY-SYSTEM>` =
+   SYS_DVBC_ANNEX_A
+
+-  :ref:`DTV_FREQUENCY <DTV-FREQUENCY>` = 651000000
+
+-  :ref:`DTV_MODULATION <DTV-MODULATION>` = QAM_256
+
+-  :ref:`DTV_INVERSION <DTV-INVERSION>` = INVERSION_AUTO
+
+-  :ref:`DTV_SYMBOL_RATE <DTV-SYMBOL-RATE>` = 5217000
+
+-  :ref:`DTV_INNER_FEC <DTV-INNER-FEC>` = FEC_3_4
+
+-  :ref:`DTV_TUNE <DTV-TUNE>`
+
+The code that would that would do the above is show in
+:ref:`dtv-prop-example`.

+The program assumes that you are using a universal LNB and a standard
+DiSEqC switch with up to 4 addresses. Of course, you could build in some
+more checking if tuning was successful and maybe try to repeat the
+tuning process. Depending on the external hardware, i.e. LNB and DiSEqC
+switch, and weather conditions this may be necessary.

+
+
+Description
+===========
+
+This ioctl call returns a frontend event if available. If an event is
+not available, the behavior depends on whether the device is in blocking
+or non-blocking mode. In the latter case, the call fails immediately
+with errno set to ``EWOULDBLOCK``. In the former case, the call blocks until
+an event becomes available.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+===========
+
+All DVB frontend devices support the ``FE_SET_PROPERTY`` and

+depends on the delivery system and on the device:
+
+-  ``FE_SET_PROPERTY:``
+
+   -  This ioctl is used to set one or more frontend properties.
+
+   -  This is the basic command to request the frontend to tune into
+      some frequency and to start decoding the digital TV signal.
+
+   -  This call requires read/write access to the device.
+
+   -  At return, the values are updated to reflect the actual parameters
+      used.
+
+-  ``FE_GET_PROPERTY:``
+
+   -  This ioctl is used to get properties and statistics from the
+      frontend.
+
+   -  No properties are changed, and statistics aren't reset.
+
+   -  This call only requires read-only access to the device.
+

+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set

+
+All DVB frontend devices support the ``FE_READ_STATUS`` ioctl. It is
+used to check about the locking status of the frontend after being
+tuned. The ioctl takes a pointer to an integer where the status will be
+written.

+
+  #. DVB-T supports 6, 7 and 8MHz.

+
+  #. ISDB-T supports 5MHz, 6MHz, 7MHz and 8MHz, although most
+     places use 6MHz.
+
+  #. On DVB-C and DVB-S/S2, the bandwidth depends on the symbol rate.
+     So, the Kernel will silently ignore setting :ref:`DTV-BANDWIDTH-HZ`.
+
+  #. For DVB-C and DVB-S/S2, the Kernel will return an estimation of the
+     bandwidth, calculated from :ref:`DTV-SYMBOL-RATE` and from
+     the rolloff, with is fixed for DVB-C and DVB-S.
+
+  #. For DVB-S2, the bandwidth estimation will use :ref:`DTV-ROLLOFF`.
+
+  #. For ISDB-Tsb, it can vary depending on the number of connected
+     segments.
+
+  #. Bandwidth in ISDB-Tsb can be easily derived from other parameters
+     (DTV_ISDBT_SB_SEGMENT_IDX, DTV_ISDBT_SB_SEGMENT_COUNT).

+============================
+
+This field represents whether the other DTV_ISDBT_*-parameters are

+
+DTV_ISDBT_SB_SUBCHANNEL_ID
+==========================
+
+This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
+
+(Note of the author: This might not be the correct description of the
+``SUBCHANNEL-ID`` in all details, but it is my understanding of the
+technical background needed to program a device)
+
+An ISDB-Tsb channel (1 or 3 segments) can be broadcasted alone or in a
+set of connected ISDB-Tsb channels. In this set of channels every
+channel can be received independently. The number of connected ISDB-Tsb
+segment can vary, e.g. depending on the frequency spectrum bandwidth
+available.
+
+Example: Assume 8 ISDB-Tsb connected segments are broadcasted. The
+broadcaster has several possibilities to put those channels in the air:
+Assuming a normal 13-segment ISDB-T spectrum he can align the 8 segments
+from position 1-8 to 5-13 or anything in between.
+
+The underlying layer of segments are subchannels: each segment is
+consisting of several subchannels with a predefined IDs. A sub-channel
+is used to help the demodulator to synchronize on the channel.
+
+An ISDB-T channel is always centered over all sub-channels. As for the
+example above, in ISDB-Tsb it is no longer as simple as that.
+
+``The DTV_ISDBT_SB_SUBCHANNEL_ID`` parameter is used to give the
+sub-channel ID of the segment to be demodulated.
+
+Possible values: 0 .. 41, -1 (AUTO)
+
+
+.. _DTV-ISDBT-SB-SEGMENT-IDX:

+
+This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
+
+``DTV_ISDBT_SB_SEGMENT_IDX`` gives the index of the segment to be
+demodulated for an ISDB-Tsb channel where several of them are
+transmitted in the connected manner.
+
+Possible values: 0 .. ``DTV_ISDBT_SB_SEGMENT_COUNT`` - 1
+
+Note: This value cannot be determined by an automatic channel search.
+
+
+.. _DTV-ISDBT-SB-SEGMENT-COUNT:
+
+DTV_ISDBT_SB_SEGMENT_COUNT
+==========================
+
+This field only applies if ``DTV_ISDBT_SOUND_BROADCASTING`` is '1'.
+
+``DTV_ISDBT_SB_SEGMENT_COUNT`` gives the total count of connected
+ISDB-Tsb channels.
+
+Possible values: 1 .. 13
+
+Note: This value cannot be determined by an automatic channel search.
+
+
+.. _isdb-hierq-layers:
+
+DTV-ISDBT-LAYER[A-C] parameters
+===============================
+
+ISDB-T channels can be coded hierarchically. As opposed to DVB-T in
+ISDB-T hierarchical layers can be decoded simultaneously. For that
+reason a ISDB-T demodulator has 3 Viterbi and 3 Reed-Solomon decoders.
+
+ISDB-T has 3 hierarchical layers which each can use a part of the
+available segments. The total number of segments over all layers has to
+13 in ISDB-T.
+
+There are 3 parameter sets, for Layers A, B and C.
+
+
+.. _DTV-ISDBT-LAYER-ENABLED:
+
+DTV_ISDBT_LAYER_ENABLED
+-----------------------
+
+Hierarchical reception in ISDB-T is achieved by enabling or disabling
+layers in the decoding process. Setting all bits of
+``DTV_ISDBT_LAYER_ENABLED`` to '1' forces all layers (if applicable) to
+be demodulated. This is the default.
+
+If the channel is in the partial reception mode
+(``DTV_ISDBT_PARTIAL_RECEPTION`` = 1) the central segment can be decoded
+independently of the other 12 segments. In that mode layer A has to have
+a ``SEGMENT_COUNT`` of 1.
+
+In ISDB-Tsb only layer A is used, it can be 1 or 3 in ISDB-Tsb according
+to ``DTV_ISDBT_PARTIAL_RECEPTION``. ``SEGMENT_COUNT`` must be filled
+accordingly.
+
+Only the values of the first 3 bits are used. Other bits will be silently ignored:
+
+``DTV_ISDBT_LAYER_ENABLED`` bit 0: layer A enabled
+
+``DTV_ISDBT_LAYER_ENABLED`` bit 1: layer B enabled
+
+``DTV_ISDBT_LAYER_ENABLED`` bit 2: layer C enabled

+substream filtering is disabled.
+
+For DVB-S2 and DVB-T2, the valid substream id range is from 0 to 255.
+
+For ISDB, the valid substream id range is from 1 to 65535.
+
+To disable it, you should use the special macro NO_STREAM_ID_FILTER.

+
+A Multi standard frontend needs to advertise the delivery systems

+before using any other operation with the frontend. Prior to it's
+introduction, FE_GET_INFO was used to determine a frontend type. A
+frontend which provides more than a single delivery system,
+FE_GET_INFO doesn't help much. Applications which intends to use a
+multistandard frontend must enumerate the delivery systems associated
+with it, rather than trying to use FE_GET_INFO. In the case of a
+legacy frontend, the result is just the same as with FE_GET_INFO, but

+ISDB-T delivery system
+======================
+
+This ISDB-T/ISDB-Tsb API extension should reflect all information needed
+to tune any ISDB-T/ISDB-Tsb hardware. Of course it is possible that some
+very sophisticated devices won't need certain parameters to tune.
+
+The information given here should help application writers to know how
+to handle ISDB-T and ISDB-Tsb hardware using the Linux DVB-API.
+
+The details given here about ISDB-T and ISDB-Tsb are just enough to
+basically show the dependencies between the needed parameter values, but
+surely some information is left out. For more detailed information see
+the following documents:
+
+ARIB STD-B31 - "Transmission System for Digital Terrestrial Television
+Broadcasting" and
+
+ARIB TR-B14 - "Operational Guidelines for Digital Terrestrial Television
+Broadcasting".
+
+In order to understand the ISDB specific parameters, one has to have
+some knowledge the channel structure in ISDB-T and ISDB-Tsb. I.e. it has
+to be known to the reader that an ISDB-T channel consists of 13
+segments, that it can have up to 3 layer sharing those segments, and
+things like that.

+
+******************************
+Frontend statistics indicators
+******************************
+
+The values are returned via ``dtv_property.stat``. If the property is
+supported, ``dtv_property.stat.len`` is bigger than zero.
+
+For most delivery systems, ``dtv_property.stat.len`` will be 1 if the
+stats is supported, and the properties will return a single value for
+each parameter.
+
+It should be noted, however, that new OFDM delivery systems like ISDB
+can use different modulation types for each group of carriers. On such
+standards, up to 3 groups of statistics can be provided, and
+``dtv_property.stat.len`` is updated to reflect the "global" metrics,
+plus one metric per each carrier group (called "layer" on ISDB).
+
+So, in order to be consistent with other delivery systems, the first
+value at :ref:`dtv_property.stat.dtv_stats <dtv-stats>` array refers
+to the global metric. The other elements of the array represent each
+layer, starting from layer A(index 1), layer B (index 2) and so on.
+
+The number of filled elements are stored at ``dtv_property.stat.len``.
+
+Each element of the ``dtv_property.stat.dtv_stats`` array consists on
+two elements:
+
+-  ``svalue`` or ``uvalue``, where ``svalue`` is for signed values of
+   the measure (dB measures) and ``uvalue`` is for unsigned values
+   (counters, relative scale)
+
+-  ``scale`` - Scale for the value. It can be:
+
+   -  ``FE_SCALE_NOT_AVAILABLE`` - The parameter is supported by the
+      frontend, but it was not possible to collect it (could be a
+      transitory or permanent condition)
+
+   -  ``FE_SCALE_DECIBEL`` - parameter is a signed value, measured in
+      1/1000 dB
+
+   -  ``FE_SCALE_RELATIVE`` - parameter is a unsigned value, where 0
+      means 0% and 65535 means 100%.
+
+   -  ``FE_SCALE_COUNTER`` - parameter is a unsigned value that counts
+      the occurrence of an event, like bit error, block error, or lapsed
+      time.
+
+
+.. _DTV-STAT-SIGNAL-STRENGTH:
+
+DTV_STAT_SIGNAL_STRENGTH
+========================
+
+Indicates the signal strength level at the analog part of the tuner or
+of the demod.
+
+Possible scales for this metric are:
+
+-  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
+   measurement was not complete yet.
+
+-  ``FE_SCALE_DECIBEL`` - signal strength is in 0.001 dBm units, power
+   measured in miliwatts. This value is generally negative.
+
+-  ``FE_SCALE_RELATIVE`` - The frontend provides a 0% to 100%
+   measurement for power (actually, 0 to 65535).
+
+
+.. _DTV-STAT-CNR:
+
+DTV_STAT_CNR
+============
+
+Indicates the Signal to Noise ratio for the main carrier.
+
+Possible scales for this metric are:
+
+-  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
+   measurement was not complete yet.
+
+-  ``FE_SCALE_DECIBEL`` - Signal/Noise ratio is in 0.001 dB units.
+
+-  ``FE_SCALE_RELATIVE`` - The frontend provides a 0% to 100%
+   measurement for Signal/Noise (actually, 0 to 65535).
+
+
+.. _DTV-STAT-PRE-ERROR-BIT-COUNT:
+
+DTV_STAT_PRE_ERROR_BIT_COUNT
+============================
+
+Measures the number of bit errors before the forward error correction
+(FEC) on the inner coding block (before Viterbi, LDPC or other inner
+code).
+
+This measure is taken during the same interval as
+``DTV_STAT_PRE_TOTAL_BIT_COUNT``.
+
+In order to get the BER (Bit Error Rate) measurement, it should be
+divided by
+:ref:`DTV_STAT_PRE_TOTAL_BIT_COUNT <DTV-STAT-PRE-TOTAL-BIT-COUNT>`.
+
+This measurement is monotonically increased, as the frontend gets more
+bit count measurements. The frontend may reset it when a
+channel/transponder is tuned.
+
+Possible scales for this metric are:
+
+-  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
+   measurement was not complete yet.
+
+-  ``FE_SCALE_COUNTER`` - Number of error bits counted before the inner
+   coding.
+
+
+.. _DTV-STAT-PRE-TOTAL-BIT-COUNT:
+
+DTV_STAT_PRE_TOTAL_BIT_COUNT
+============================
+
+Measures the amount of bits received before the inner code block, during
+the same period as
+:ref:`DTV_STAT_PRE_ERROR_BIT_COUNT <DTV-STAT-PRE-ERROR-BIT-COUNT>`
+measurement was taken.
+
+It should be noted that this measurement can be smaller than the total
+amount of bits on the transport stream, as the frontend may need to
+manually restart the measurement, losing some data between each
+measurement interval.
+
+This measurement is monotonically increased, as the frontend gets more
+bit count measurements. The frontend may reset it when a
+channel/transponder is tuned.
+
+Possible scales for this metric are:
+
+-  ``FE_SCALE_NOT_AVAILABLE`` - it failed to measure it, or the
+   measurement was not complete yet.
+
+-  ``FE_SCALE_COUNTER`` - Number of bits counted while measuring
+   :ref:`DTV_STAT_PRE_ERROR_BIT_COUNT <DTV-STAT-PRE-ERROR-BIT-COUNT>`.
+
+
+.. _DTV-STAT-POST-ERROR-BIT-COUNT:
+
+DTV_STAT_POST_ERROR_BIT_COUNT
+=============================
+
+Measures the number of bit errors after the forward error correction
+(FEC) done by inner code block (after Viterbi, LDPC or other inner
+code).
+
+This measure is taken during the same interval as
+``DTV_STAT_POST_TOTAL_BIT_COUNT``.
+
+In order to get the BER (Bit Error Rate) measurement, it should be
+divided by
+:ref:`DTV_STAT_POST_TOTAL_BIT_COUNT <DTV-STAT-POST-TOTAL-BIT-COUNT>`.

+DVB Frontend API
+################
+The DVB frontend API was designed to support three types of delivery
+systems:
+
+-  Terrestrial systems: DVB-T, DVB-T2, ATSC, ATSC M/H, ISDB-T, DVB-H,
+   DTMB, CMMB
+
+-  Cable systems: DVB-C Annex A/C, ClearQAM (DVB-C Annex B), ISDB-C
+
+-  Satellite systems: DVB-S, DVB-S2, DVB Turbo, ISDB-S, DSS
+
+The DVB frontend controls several sub-devices including:
+
+-  Tuner
+
+-  Digital TV demodulator
+
+-  Low noise amplifier (LNA)
+
+-  Satellite Equipment Control (SEC) hardware (only for Satellite).
+
+The frontend can be accessed through ``/dev/dvb/adapter?/frontend?``.
+Data types and ioctl definitions can be accessed by including
+``linux/dvb/frontend.h`` in your application.
+
+.. note:: Transmission via the internet (DVB-IP) is not yet handled by this
+   API but a future extension is possible.
+
+On Satellite systems, the API support for the Satellite Equipment
+Control (SEC) allows to power control and to send/receive signals to
+control the antenna subsystem, selecting the polarization and choosing
+the Intermediate Frequency IF) of the Low Noise Block Converter Feed
+Horn (LNBf). It supports the DiSEqC and V-SEC protocols. The DiSEqC
+(digital SEC) specification is available at
+`Eutelsat <http://www.eutelsat.com/satellites/4_5_5.html>`__.

+
+    Other flags have no effect.
+
+
+Description
+===========
+
+This system call opens a named frontend device
+(``/dev/dvb/adapter?/frontend?``) for subsequent use. Usually the first
+thing to do after a successful open is to find out the frontend type
+with :ref:`FE_GET_INFO`.
+
+The device can be opened in read-only mode, which only allows monitoring
+of device status and statistics, or read/write mode, which allows any
+kind of use (e.g. performing tuning operations.)
+
+In a system with multiple front-ends, it is usually the case that
+multiple devices cannot be open in read/write mode simultaneously. As
+long as a front-end device is opened in read/write mode, other open()
+calls in read/write mode will either fail or block, depending on whether
+non-blocking or blocking mode was specified. A front-end device opened
+in blocking mode can later be put into non-blocking mode (and vice
+versa) using the F_SETFL command of the fcntl system call. This is a
+standard system call, documented in the Linux manual page for fcntl.
+When an open() call has succeeded, the device will be ready for use in
+the specified mode. This implies that the corresponding hardware is
+powered up, and that other front-ends may have been powered down to make
+that possible.
+
+
+Return Value
+============
+
+On success :ref:`open() <frontend_f_open>` returns the new file descriptor.
+On error, -1 is returned, and the ``errno`` variable is set appropriately.
+
+Possible error codes are:
+
+EACCES
+    The caller has no permission to access the device.
+
+EBUSY
+    The the device driver is already in use.
+
+ENXIO
+    No device corresponding to this device special file exists.
+
+ENOMEM
+    Not enough kernel memory was available to complete the request.
+
+EMFILE
+    The process already has the maximum number of files open.
+
+ENFILE
+    The limit on the total number of files open on the system has been
+    reached.
+
+ENODEV
+    The device got removed.

+.. _requisites:
+
+What you need to know
+=====================
+
+The reader of this document is required to have some knowledge in the
+area of digital video broadcasting (DVB) and should be familiar with
+part I of the MPEG2 specification ISO/IEC 13818 (aka ITU-T H.222), i.e
+you should know what a program/transport stream (PS/TS) is and what is
+meant by a packetized elementary stream (PES) or an I-frame.
+
+Various DVB standards documents are available from http://www.dvb.org
+and/or http://www.etsi.org.
+
+It is also necessary to know how to access unix/linux devices and how to
+use ioctl calls. This also includes the knowledge of C or C++.
+
+
+.. _history:
+
+History
+=======
+
+The first API for DVB cards we used at Convergence in late 1999 was an
+extension of the Video4Linux API which was primarily developed for frame
+grabber cards. As such it was not really well suited to be used for DVB
+cards and their new features like recording MPEG streams and filtering
+several section and PES data streams at the same time.
+
+In early 2000, we were approached by Nokia with a proposal for a new
+standard Linux DVB API. As a commitment to the development of terminals
+based on open standards, Nokia and Convergence made it available to all
+Linux developers and published it on https://linuxtv.org in September
+2000. Convergence is the maintainer of the Linux DVB API. Together with
+the LinuxTV community (i.e. you, the reader of this document), the Linux
+DVB API will be constantly reviewed and improved. With the Linux driver
+for the Siemens/Hauppauge DVB PCI card Convergence provides a first
+implementation of the Linux DVB API.

+    :alt:    dvbstb.pdf / dvbstb.png
+    :align:  center
+
+    Components of a DVB card/STB
+
+A DVB PCI card or DVB set-top-box (STB) usually consists of the
+following main hardware components:
+
+-  Frontend consisting of tuner and DVB demodulator
+
+   Here the raw signal reaches the DVB hardware from a satellite dish or
+   antenna or directly from cable. The frontend down-converts and
+   demodulates this signal into an MPEG transport stream (TS). In case
+   of a satellite frontend, this includes a facility for satellite
+   equipment control (SEC), which allows control of LNB polarization,
+   multi feed switches or dish rotors.
+
+-  Conditional Access (CA) hardware like CI adapters and smartcard slots
+
+   The complete TS is passed through the CA hardware. Programs to which
+   the user has access (controlled by the smart card) are decoded in
+   real time and re-inserted into the TS.
+
+-  Demultiplexer which filters the incoming DVB stream
+
+   The demultiplexer splits the TS into its components like audio and
+   video streams. Besides usually several of such audio and video
+   streams it also contains data streams with information about the
+   programs offered in this or other streams of the same provider.
+
+-  MPEG2 audio and video decoder
+
+   The main targets of the demultiplexer are the MPEG2 audio and video
+   decoders. After decoding they pass on the uncompressed audio and
+   video to the computer screen or (through a PAL/NTSC encoder) to a TV
+   set.
+
+:ref:`stb_components` shows a crude schematic of the control and data
+flow between those components.
+
+On a DVB PCI card not all of these have to be present since some
+functionality can be provided by the main CPU of the PC (e.g. MPEG
+picture and sound decoding) or is not needed (e.g. for data-only uses
+like “internet over satellite”). Also not every card or STB provides
+conditional access hardware.
+
+
+.. _dvb_devices:
+
+Linux DVB Devices
+=================
+
+The Linux DVB API lets you control these hardware components through
+currently six Unix-style character devices for video, audio, frontend,
+demux, CA and IP-over-DVB networking. The video and audio devices
+control the MPEG2 decoder hardware, the frontend device the tuner and
+the DVB demodulator. The demux device gives you control over the PES and
+section filters of the hardware. If the hardware does not support
+filtering these filters can be implemented in software. Finally, the CA
+device controls all the conditional access capabilities of the hardware.
+It can depend on the individual security requirements of the platform,
+if and how many of the CA functions are made available to the
+application through this device.
+
+All devices can be found in the ``/dev`` tree under ``/dev/dvb``. The
+individual devices are called:
+
+-  ``/dev/dvb/adapterN/audioM``,
+
+-  ``/dev/dvb/adapterN/videoM``,
+
+-  ``/dev/dvb/adapterN/frontendM``,
+
+-  ``/dev/dvb/adapterN/netM``,
+
+-  ``/dev/dvb/adapterN/demuxM``,
+
+-  ``/dev/dvb/adapterN/dvrM``,
+
+-  ``/dev/dvb/adapterN/caM``,
+
+where N enumerates the DVB PCI cards in a system starting from 0, and M
+enumerates the devices of each type within each adapter, starting
+from 0, too. We will omit the “ ``/dev/dvb/adapterN/``\ ” in the further
+discussion of these devices.
+
+More details about the data structures and function calls of all the
+devices are described in the following chapters.
+
+
+.. _include_files:
+
+API include files
+=================
+
+For each of the DVB devices a corresponding include file exists. The DVB
+API include files should be included in application sources with a
+partial path like:
+
+
+.. code-block:: c
+
+	#include <linux/dvb/ca.h>
+
+	#include <linux/dvb/dmx.h>
+
+	#include <linux/dvb/frontend.h>
+
+	#include <linux/dvb/net.h>
+
+
+To enable applications to support different API version, an additional
+include file ``linux/dvb/version.h`` exists, which defines the constant
+``DVB_API_VERSION``. This document describes ``DVB_API_VERSION 5.10``.

+    pointer to struct :ref:`dvb_net_if <dvb-net-if>`
+
+
+Description
+===========
+
+The NET_GET_IF ioctl uses the interface number given by the struct
+:ref:`dvb_net_if <dvb-net-if>`::ifnum field and fills the content of
+struct :ref:`dvb_net_if <dvb-net-if>` with the packet ID and
+encapsulation type used on such interface. If the interface was not
+created yet with :ref:`NET_ADD_IF <net>`, it will return -1 and fill
+the ``errno`` with ``EINVAL`` error code.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+###############
+DVB Network API
+###############
+The DVB net device controls the mapping of data packages that are part
+of a transport stream to be mapped into a virtual network interface,
+visible through the standard Linux network protocol stack.
+
+Currently, two encapsulations are supported:
+
+-  `Multi Protocol Encapsulation (MPE) <http://en.wikipedia.org/wiki/Multiprotocol_Encapsulation>`__
+
+-  `Ultra Lightweight Encapsulation (ULE) <http://en.wikipedia.org/wiki/Unidirectional_Lightweight_Encapsulation>`__
+
+In order to create the Linux virtual network interfaces, an application
+needs to tell to the Kernel what are the PIDs and the encapsulation
+types that are present on the transport stream. This is done through
+``/dev/dvb/adapter?/net?`` device node. The data will be available via
+virtual ``dvb?_?`` network interfaces, and will be controlled/routed via
+the standard ip tools (like ip, route, netstat, ifconfig, etc).
+
+Data types and and ioctl definitions are defined via ``linux/dvb/net.h``
+header.

+-----------
+
+This system call opens a named video device (e.g.

+
+When an open() call has succeeded, the device will be ready for use. The
+significance of blocking or non-blocking mode is described in the
+documentation for functions where there is a difference. It does not
+affect the semantics of the open() call itself. A device opened in
+blocking mode can later be put into non-blocking mode (and vice versa)
+using the F_SETFL command of the fcntl system call. This is a standard
+system call, documented in the Linux manual page for fcntl. Only one
+user can open the Video Device in O_RDWR mode. All other attempts to
+open the device in this mode will fail, and an error-code will be
+returned. If the Video Device is opened in O_RDONLY mode, the only
+ioctl call that can be used is VIDEO_GET_STATUS. All other call will
+return an error code.

+use the V4L2 :ref:`VIDIOC_DQEVENT` ioctl instead.
+
+This ioctl call returns an event of type video_event if available. If
+an event is not available, the behavior depends on whether the device is
+in blocking or non-blocking mode. In the latter case, the call fails
+immediately with errno set to ``EWOULDBLOCK``. In the former case, the call
+blocks until an event becomes available. The standard Linux poll()
+and/or select() system calls can be used with the device file descriptor
+to watch for new events. For select(), the file descriptor should be
+included in the exceptfds argument, and for poll(), POLLPRI should be
+specified as the wake-up condition. Read-only permissions are sufficient
+for this ioctl call.
+
+
+Return Value
+------------
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.

+################
+DVB Video Device
+################
+The DVB video device controls the MPEG2 video decoder of the DVB
+hardware. It can be accessed through **/dev/dvb/adapter0/video0**. Data
+types and and ioctl definitions can be accessed by including
+**linux/dvb/video.h** in your application.
+
+Note that the DVB video device only controls decoding of the MPEG video
+stream, not its presentation on the TV or computer screen. On PCs this
+is typically handled by an associated video4linux device, e.g.
+**/dev/video**, which allows scaling and defining output windows.
+
+Some DVB cards don’t have their own MPEG decoder, which results in the
+omission of the audio and video device as well as the video4linux
+device.
+
+The ioctls that deal with SPUs (sub picture units) and navigation
+packets are only supported on some MPEG decoders made for DVD playback.
+
+These ioctls were also used by V4L2 to control MPEG decoders implemented
+in V4L2. The use of these ioctls for that purpose has been made obsolete
+and proper V4L2 ioctls or controls have been created to replace that
+functionality.

+	VIDEO_FORMAT_16_9,    /* Select 16:9 format. */
+	VIDEO_FORMAT_221_1    /* 2.21:1 */
+    } video_format_t;
+
+is used in the VIDEO_SET_FORMAT function (??) to tell the driver which
+aspect ratio the output hardware (e.g. TV) has. It is also used in the
+data structures video_status (??) returned by VIDEO_GET_STATUS (??)
+and video_event (??) returned by VIDEO_GET_EVENT (??) which report
+about the display format of the current video stream.
+
+
+.. _video-displayformat-t:
+
+video_displayformat_t
+=====================
+
+In case the display format of the video stream and of the display
+hardware differ the application has to specify how to handle the
+cropping of the picture. This can be done using the
+VIDEO_SET_DISPLAY_FORMAT call (??) which accepts
+
+
+.. code-block:: c
+
+    typedef enum {
+	VIDEO_PAN_SCAN,       /* use pan and scan format */
+	VIDEO_LETTER_BOX,     /* use letterbox format */
+	VIDEO_CENTER_CUT_OUT  /* use center cut out format */
+    } video_displayformat_t;
+
+as argument.
+
+
+.. _video-stream-source-t:
+
+video_stream_source_t
+=====================
+
+The video stream source is set through the VIDEO_SELECT_SOURCE call
+and can take the following values, depending on whether we are replaying
+from an internal (demuxer) or external (user write) source.
+
+
+.. code-block:: c
+
+    typedef enum {
+	VIDEO_SOURCE_DEMUX, /* Select the demux as the main source */
+	VIDEO_SOURCE_MEMORY /* If this source is selected, the stream
+		       comes from the user through the write
+		       system call */
+    } video_stream_source_t;
+
+VIDEO_SOURCE_DEMUX selects the demultiplexer (fed either by the
+frontend or the DVR device) as the source of the video stream. If
+VIDEO_SOURCE_MEMORY is selected the stream comes from the application
+through the **write()** system call.
+
+
+.. _video-play-state-t:
+
+video_play_state_t
+==================
+
+The following values can be returned by the VIDEO_GET_STATUS call
+representing the state of video playback.
+
+
+.. code-block:: c
+
+    typedef enum {
+	VIDEO_STOPPED, /* Video is stopped */
+	VIDEO_PLAYING, /* Video is currently playing */
+	VIDEO_FREEZED  /* Video is freezed */
+    } video_play_state_t;
+
+
+.. _video-command:
+
+struct video_command
+====================
+
+The structure must be zeroed before use by the application This ensures
+it can be extended safely in the future.
+
+
+.. code-block:: c
+
+    struct video_command {
+	__u32 cmd;
+	__u32 flags;
+	union {
+	    struct {
+		__u64 pts;
+	    } stop;
+
+	    struct {
+		/* 0 or 1000 specifies normal speed,
+		   1 specifies forward single stepping,
+		   -1 specifies backward single stepping,
+		   >>1: playback at speed/1000 of the normal speed,
+		   <-1: reverse playback at (-speed/1000) of the normal speed. */
+		__s32 speed;
+		__u32 format;
+	    } play;
+
+	    struct {
+		__u32 data[16];
+	    } raw;
+	};
+    };
+
+
+.. _video-size-t:
+
+video_size_t
+============
+
+
+.. code-block:: c
+
+    typedef struct {
+	int w;
+	int h;
+	video_format_t aspect_ratio;
+    } video_size_t;
+
+
+.. _video-event:
+
+struct video_event
+==================
+
+The following is the structure of a video event as it is returned by the
+VIDEO_GET_EVENT call.
+
+
+.. code-block:: c
+
+    struct video_event {
+	__s32 type;
+    #define VIDEO_EVENT_SIZE_CHANGED    1
+    #define VIDEO_EVENT_FRAME_RATE_CHANGED  2
+    #define VIDEO_EVENT_DECODER_STOPPED     3
+    #define VIDEO_EVENT_VSYNC       4
+	__kernel_time_t timestamp;
+	union {
+	    video_size_t size;
+	    unsigned int frame_rate;    /* in frames per 1000sec */
+	    unsigned char vsync_field;  /* unknown/odd/even/progressive */
+	} u;
+    };
+
+
+.. _video-status:
+
+struct video_status
+===================
+
+The VIDEO_GET_STATUS call returns the following structure informing
+about various states of the playback operation.
+
+
+.. code-block:: c
+
+    struct video_status {
+	int                   video_blank;   /* blank video on freeze? */
+	video_play_state_t    play_state;    /* current state of playback */
+	video_stream_source_t stream_source; /* current source (demux/memory) */
+	video_format_t        video_format;  /* current aspect ratio of stream */
+	video_displayformat_t display_format;/* selected cropping mode */
+    };
+
+If video_blank is set video will be blanked out if the channel is
+changed or if playback is stopped. Otherwise, the last picture will be
+displayed. play_state indicates if the video is currently frozen,
+stopped, or being played back. The stream_source corresponds to the
+seleted source for the video stream. It can come either from the
+demultiplexer or from memory. The video_format indicates the aspect
+ratio (one of 4:3 or 16:9) of the currently played video stream.
+Finally, display_format corresponds to the selected cropping mode in
+case the source video format is not the same as the format of the output
+device.
+
+
+.. _video-still-picture:
+
+struct video_still_picture
+==========================
+
+An I-frame displayed via the VIDEO_STILLPICTURE call is passed on
+within the following structure.
+
+
+.. code-block:: c
+
+    /* pointer to and size of a single iframe in memory */
+    struct video_still_picture {
+	char *iFrame;        /* pointer to a single iframe in memory */
+	int32_t size;
+    };
+
+
+.. _video_caps:
+
+video capabilities
+==================
+
+A call to VIDEO_GET_CAPABILITIES returns an unsigned integer with the
+following bits set according to the hardwares capabilities.
+
+
+.. code-block:: c
+
+     /* bit definitions for capabilities: */
+     /* can the hardware decode MPEG1 and/or MPEG2? */
+     #define VIDEO_CAP_MPEG1   1
+     #define VIDEO_CAP_MPEG2   2
+     /* can you send a system and/or program stream to video device?
+	(you still have to open the video and the audio device but only
+	 send the stream to the video device) */
+     #define VIDEO_CAP_SYS     4
+     #define VIDEO_CAP_PROG    8
+     /* can the driver also handle SPU, NAVI and CSS encoded data?
+	(CSS API is not present yet) */
+     #define VIDEO_CAP_SPU    16
+     #define VIDEO_CAP_NAVI   32
+     #define VIDEO_CAP_CSS    64
+
+
+.. _video-system:
+
+video_system_t
+==============
+
+A call to VIDEO_SET_SYSTEM sets the desired video system for TV
+output. The following system types can be set:
+
+
+.. code-block:: c
+
+    typedef enum {
+	 VIDEO_SYSTEM_PAL,
+	 VIDEO_SYSTEM_NTSC,
+	 VIDEO_SYSTEM_PALN,
+	 VIDEO_SYSTEM_PALNc,
+	 VIDEO_SYSTEM_PALM,
+	 VIDEO_SYSTEM_NTSC60,
+	 VIDEO_SYSTEM_PAL60,
+	 VIDEO_SYSTEM_PALM60
+    } video_system_t;
+
+
+.. _video-highlight:
+
+struct video_highlight
+======================
+
+Calling the ioctl VIDEO_SET_HIGHLIGHTS posts the SPU highlight
+information. The call expects the following format for that information:
+
+
+.. code-block:: c
+
+     typedef
+     struct video_highlight {
+	 boolean active;      /*    1=show highlight, 0=hide highlight */
+	 uint8_t contrast1;   /*    7- 4  Pattern pixel contrast */
+		      /*    3- 0  Background pixel contrast */
+	 uint8_t contrast2;   /*    7- 4  Emphasis pixel-2 contrast */
+		      /*    3- 0  Emphasis pixel-1 contrast */
+	 uint8_t color1;      /*    7- 4  Pattern pixel color */
+		      /*    3- 0  Background pixel color */
+	 uint8_t color2;      /*    7- 4  Emphasis pixel-2 color */
+		      /*    3- 0  Emphasis pixel-1 color */
+	 uint32_t ypos;       /*   23-22  auto action mode */
+		      /*   21-12  start y */
+		      /*    9- 0  end y */
+	 uint32_t xpos;       /*   23-22  button color number */
+		      /*   21-12  start x */
+		      /*    9- 0  end x */
+     } video_highlight_t;
+
+
+.. _video-spu:
+
+struct video_spu
+================
+
+Calling VIDEO_SET_SPU deactivates or activates SPU decoding, according
+to the following format:
+
+
+.. code-block:: c
+
+     typedef
+     struct video_spu {
+	 boolean active;
+	 int stream_id;
+     } video_spu_t;
+
+
+.. _video-spu-palette:
+
+struct video_spu_palette
+========================
+
+The following structure is used to set the SPU palette by calling
+VIDEO_SPU_PALETTE:
+
+
+.. code-block:: c
+
+     typedef
+     struct video_spu_palette {
+	 int length;
+	 uint8_t *palette;
+     } video_spu_palette_t;
+
+
+.. _video-navi-pack:
+
+struct video_navi_pack
+======================
+
+In order to get the navigational data the following structure has to be
+passed to the ioctl VIDEO_GET_NAVI:
+
+
+.. code-block:: c
+
+     typedef
+     struct video_navi_pack {
+	 int length;         /* 0 ... 1024 */
+	 uint8_t data[1024];
+     } video_navi_pack_t;

+GNU Free Documentation License
+******************************
+
+
+.. _fdl-preamble:
+
+0. PREAMBLE
+===========
+
+The purpose of this License is to make a manual, textbook, or other
+written document “free” in the sense of freedom: to assure everyone the
+effective freedom to copy and redistribute it, with or without modifying
+it, either commercially or noncommercially. Secondarily, this License
+preserves for the author and publisher a way to get credit for their
+work, while not being considered responsible for modifications made by
+others.
+
+This License is a kind of “copyleft”, which means that derivative works
+of the document must themselves be free in the same sense. It
+complements the GNU General Public License, which is a copyleft license
+designed for free software.
+
+We have designed this License in order to use it for manuals for free
+software, because free software needs free documentation: a free program
+should come with manuals providing the same freedoms that the software
+does. But this License is not limited to software manuals; it can be
+used for any textual work, regardless of subject matter or whether it is
+published as a printed book. We recommend this License principally for
+works whose purpose is instruction or reference.
+
+
+.. _fdl-section1:
+
+1. APPLICABILITY AND DEFINITIONS
+================================
+
+
+.. _fdl-document:
+
+This License applies to any manual or other work that contains a notice
+placed by the copyright holder saying it can be distributed under the
+terms of this License. The “Document”, below, refers to any such manual
+or work. Any member of the public is a licensee, and is addressed as
+“you”.
+
+
+.. _fdl-modified:
+
+A “Modified Version” of the Document means any work containing the
+Document or a portion of it, either copied verbatim, or with
+modifications and/or translated into another language.
+
+
+.. _fdl-secondary:
+
+A “Secondary Section” is a named appendix or a front-matter section of
+the :ref:`Document <fdl-document>` that deals exclusively with the
+relationship of the publishers or authors of the Document to the
+Document's overall subject (or to related matters) and contains nothing
+that could fall directly within that overall subject. (For example, if
+the Document is in part a textbook of mathematics, a Secondary Section
+may not explain any mathematics.) The relationship could be a matter of
+historical connection with the subject or with related matters, or of
+legal, commercial, philosophical, ethical or political position
+regarding them.
+
+
+.. _fdl-invariant:
+
+The “Invariant Sections” are certain
+:ref:`Secondary Sections <fdl-secondary>` whose titles are designated,
+as being those of Invariant Sections, in the notice that says that the
+:ref:`Document <fdl-document>` is released under this License.
+
+
+.. _fdl-cover-texts:
+
+The “Cover Texts” are certain short passages of text that are listed, as
+Front-Cover Texts or Back-Cover Texts, in the notice that says that the
+:ref:`Document <fdl-document>` is released under this License.
+
+
+.. _fdl-transparent:
+
+A “Transparent” copy of the :ref:`Document <fdl-document>` means a
+machine-readable copy, represented in a format whose specification is
+available to the general public, whose contents can be viewed and edited
+directly and straightforwardly with generic text editors or (for images
+composed of pixels) generic paint programs or (for drawings) some widely
+available drawing editor, and that is suitable for input to text
+formatters or for automatic translation to a variety of formats suitable
+for input to text formatters. A copy made in an otherwise Transparent
+file format whose markup has been designed to thwart or discourage
+subsequent modification by readers is not Transparent. A copy that is
+not “Transparent” is called “Opaque”.
+
+Examples of suitable formats for Transparent copies include plain ASCII
+without markup, Texinfo input format, LaTeX input format, SGML or XML
+using a publicly available DTD, and standard-conforming simple HTML
+designed for human modification. Opaque formats include PostScript, PDF,
+proprietary formats that can be read and edited only by proprietary word
+processors, SGML or XML for which the DTD and/or processing tools are
+not generally available, and the machine-generated HTML produced by some
+word processors for output purposes only.
+
+
+.. _fdl-title-page:
+
+The “Title Page” means, for a printed book, the title page itself, plus
+such following pages as are needed to hold, legibly, the material this
+License requires to appear in the title page. For works in formats which
+do not have any title page as such, “Title Page” means the text near the
+most prominent appearance of the work's title, preceding the beginning
+of the body of the text.
+
+
+.. _fdl-section2:
+
+2. VERBATIM COPYING
+===================
+
+You may copy and distribute the :ref:`Document <fdl-document>` in any
+medium, either commercially or noncommercially, provided that this
+License, the copyright notices, and the license notice saying this
+License applies to the Document are reproduced in all copies, and that
+you add no other conditions whatsoever to those of this License. You may
+not use technical measures to obstruct or control the reading or further
+copying of the copies you make or distribute. However, you may accept
+compensation in exchange for copies. If you distribute a large enough
+number of copies you must also follow the conditions in
+:ref:`section 3 <fdl-section3>`.
+
+You may also lend copies, under the same conditions stated above, and
+you may publicly display copies.
+
+
+.. _fdl-section3:
+
+3. COPYING IN QUANTITY
+======================
+
+If you publish printed copies of the :ref:`Document <fdl-document>`
+numbering more than 100, and the Document's license notice requires
+:ref:`Cover Texts <fdl-cover-texts>`, you must enclose the copies in
+covers that carry, clearly and legibly, all these Cover Texts:
+Front-Cover Texts on the front cover, and Back-Cover Texts on the back
+cover. Both covers must also clearly and legibly identify you as the
+publisher of these copies. The front cover must present the full title
+with all words of the title equally prominent and visible. You may add
+other material on the covers in addition. Copying with changes limited
+to the covers, as long as they preserve the title of the
+:ref:`Document <fdl-document>` and satisfy these conditions, can be
+treated as verbatim copying in other respects.
+
+If the required texts for either cover are too voluminous to fit
+legibly, you should put the first ones listed (as many as fit
+reasonably) on the actual cover, and continue the rest onto adjacent
+pages.
+
+If you publish or distribute :ref:`Opaque <fdl-transparent>` copies of
+the :ref:`Document <fdl-document>` numbering more than 100, you must
+either include a machine-readable :ref:`Transparent <fdl-transparent>`
+copy along with each Opaque copy, or state in or with each Opaque copy a
+publicly-accessible computer-network location containing a complete
+Transparent copy of the Document, free of added material, which the
+general network-using public has access to download anonymously at no
+charge using public-standard network protocols. If you use the latter
+option, you must take reasonably prudent steps, when you begin
+distribution of Opaque copies in quantity, to ensure that this
+Transparent copy will remain thus accessible at the stated location
+until at least one year after the last time you distribute an Opaque
+copy (directly or through your agents or retailers) of that edition to
+the public.
+
+It is requested, but not required, that you contact the authors of the
+:ref:`Document <fdl-document>` well before redistributing any large
+number of copies, to give them a chance to provide you with an updated
+version of the Document.
+
+
+.. _fdl-section4:
+
+4. MODIFICATIONS
+================
+
+You may copy and distribute a :ref:`Modified Version <fdl-modified>`
+of the :ref:`Document <fdl-document>` under the conditions of sections
+:ref:`2 <fdl-section2>` and :ref:`3 <fdl-section3>` above, provided
+that you release the Modified Version under precisely this License, with
+the Modified Version filling the role of the Document, thus licensing
+distribution and modification of the Modified Version to whoever
+possesses a copy of it. In addition, you must do these things in the
+Modified Version:
+
+-  **A.**
+   Use in the :ref:`Title Page <fdl-title-page>` (and on the covers,
+   if any) a title distinct from that of the
+   :ref:`Document <fdl-document>`, and from those of previous versions
+   (which should, if there were any, be listed in the History section of
+   the Document). You may use the same title as a previous version if
+   the original publisher of that version gives permission.
+
+-  **B.**
+   List on the :ref:`Title Page <fdl-title-page>`, as authors, one or
+   more persons or entities responsible for authorship of the
+   modifications in the :ref:`Modified Version <fdl-modified>`,
+   together with at least five of the principal authors of the
+   :ref:`Document <fdl-document>` (all of its principal authors, if it
+   has less than five).
+
+-  **C.**
+   State on the :ref:`Title Page <fdl-title-page>` the name of the
+   publisher of the :ref:`Modified Version <fdl-modified>`, as the
+   publisher.
+
+-  **D.**
+   Preserve all the copyright notices of the
+   :ref:`Document <fdl-document>`.
+
+-  **E.**
+   Add an appropriate copyright notice for your modifications adjacent
+   to the other copyright notices.
+
+-  **F.**
+   Include, immediately after the copyright notices, a license notice
+   giving the public permission to use the
+   :ref:`Modified Version <fdl-modified>` under the terms of this
+   License, in the form shown in the Addendum below.
+
+-  **G.**
+   Preserve in that license notice the full lists of
+   :ref:`Invariant Sections <fdl-invariant>` and required
+   :ref:`Cover Texts <fdl-cover-texts>` given in the
+   :ref:`Document's <fdl-document>` license notice.
+
+-  **H.**
+   Include an unaltered copy of this License.
+
+-  **I.**
+   Preserve the section entitled “History”, and its title, and add to it
+   an item stating at least the title, year, new authors, and publisher
+   of the :ref:`Modified Version <fdl-modified>` as given on the
+   :ref:`Title Page <fdl-title-page>`. If there is no section entitled
+   “History” in the :ref:`Document <fdl-document>`, create one stating
+   the title, year, authors, and publisher of the Document as given on
+   its Title Page, then add an item describing the Modified Version as
+   stated in the previous sentence.
+
+-  **J.**
+   Preserve the network location, if any, given in the
+   :ref:`Document <fdl-document>` for public access to a
+   :ref:`Transparent <fdl-transparent>` copy of the Document, and
+   likewise the network locations given in the Document for previous
+   versions it was based on. These may be placed in the “History”
+   section. You may omit a network location for a work that was
+   published at least four years before the Document itself, or if the
+   original publisher of the version it refers to gives permission.
+
+-  **K.**
+   In any section entitled “Acknowledgements” or “Dedications”, preserve
+   the section's title, and preserve in the section all the substance
+   and tone of each of the contributor acknowledgements and/or
+   dedications given therein.
+
+-  **L.**
+   Preserve all the :ref:`Invariant Sections <fdl-invariant>` of the
+   :ref:`Document <fdl-document>`, unaltered in their text and in
+   their titles. Section numbers or the equivalent are not considered
+   part of the section titles.
+
+-  **M.**
+   Delete any section entitled “Endorsements”. Such a section may not be
+   included in the :ref:`Modified Version <fdl-modified>`.
+
+-  **N.**
+   Do not retitle any existing section as “Endorsements” or to conflict
+   in title with any :ref:`Invariant Section <fdl-invariant>`.
+
+If the :ref:`Modified Version <fdl-modified>` includes new
+front-matter sections or appendices that qualify as
+:ref:`Secondary Sections <fdl-secondary>` and contain no material
+copied from the Document, you may at your option designate some or all
+of these sections as invariant. To do this, add their titles to the list
+of :ref:`Invariant Sections <fdl-invariant>` in the Modified Version's
+license notice. These titles must be distinct from any other section
+titles.
+
+You may add a section entitled “Endorsements”, provided it contains
+nothing but endorsements of your
+:ref:`Modified Version <fdl-modified>` by various parties--for
+example, statements of peer review or that the text has been approved by
+an organization as the authoritative definition of a standard.
+
+You may add a passage of up to five words as a
+:ref:`Front-Cover Text <fdl-cover-texts>`, and a passage of up to 25
+words as a :ref:`Back-Cover Text <fdl-cover-texts>`, to the end of the
+list of :ref:`Cover Texts <fdl-cover-texts>` in the
+:ref:`Modified Version <fdl-modified>`. Only one passage of
+Front-Cover Text and one of Back-Cover Text may be added by (or through
+arrangements made by) any one entity. If the
+:ref:`Document <fdl-document>` already includes a cover text for the
+same cover, previously added by you or by arrangement made by the same
+entity you are acting on behalf of, you may not add another; but you may
+replace the old one, on explicit permission from the previous publisher
+that added the old one.
+
+The author(s) and publisher(s) of the :ref:`Document <fdl-document>`
+do not by this License give permission to use their names for publicity
+for or to assert or imply endorsement of any
+:ref:`Modified Version <fdl-modified>`.
+
+
+.. _fdl-section5:
+
+5. COMBINING DOCUMENTS
+======================
+
+You may combine the :ref:`Document <fdl-document>` with other
+documents released under this License, under the terms defined in
+:ref:`section 4 <fdl-section4>` above for modified versions, provided
+that you include in the combination all of the
+:ref:`Invariant Sections <fdl-invariant>` of all of the original
+documents, unmodified, and list them all as Invariant Sections of your
+combined work in its license notice.
+
+The combined work need only contain one copy of this License, and
+multiple identical :ref:`Invariant Sections <fdl-invariant>` may be
+replaced with a single copy. If there are multiple Invariant Sections
+with the same name but different contents, make the title of each such
+section unique by adding at the end of it, in parentheses, the name of
+the original author or publisher of that section if known, or else a
+unique number. Make the same adjustment to the section titles in the
+list of Invariant Sections in the license notice of the combined work.
+
+In the combination, you must combine any sections entitled “History” in
+the various original documents, forming one section entitled “History”;
+likewise combine any sections entitled “Acknowledgements”, and any
+sections entitled “Dedications”. You must delete all sections entitled
+“Endorsements.”

+
+6. COLLECTIONS OF DOCUMENTS
+===========================
+
+You may make a collection consisting of the
+:ref:`Document <fdl-document>` and other documents released under this
+License, and replace the individual copies of this License in the
+various documents with a single copy that is included in the collection,
+provided that you follow the rules of this License for verbatim copying
+of each of the documents in all other respects.
+
+You may extract a single document from such a collection, and dispbibute
+it individually under this License, provided you insert a copy of this
+License into the extracted document, and follow this License in all
+other respects regarding verbatim copying of that document.
+
+
+.. _fdl-section7:
+
+7. AGGREGATION WITH INDEPENDENT WORKS
+=====================================
+
+A compilation of the :ref:`Document <fdl-document>` or its derivatives
+with other separate and independent documents or works, in or on a
+volume of a storage or distribution medium, does not as a whole count as
+a :ref:`Modified Version <fdl-modified>` of the Document, provided no
+compilation copyright is claimed for the compilation. Such a compilation
+is called an “aggregate”, and this License does not apply to the other
+self-contained works thus compiled with the Document , on account of
+their being thus compiled, if they are not themselves derivative works
+of the Document. If the :ref:`Cover Text <fdl-cover-texts>`
+requirement of :ref:`section 3 <fdl-section3>` is applicable to these
+copies of the Document, then if the Document is less than one quarter of
+the entire aggregate, the Document's Cover Texts may be placed on covers
+that surround only the Document within the aggregate. Otherwise they
+must appear on covers around the whole aggregate.
+
+
+.. _fdl-section8:
+
+8. TRANSLATION
+==============
+
+Translation is considered a kind of modification, so you may distribute
+translations of the :ref:`Document <fdl-document>` under the terms of
+:ref:`section 4 <fdl-section4>`. Replacing
+:ref:`Invariant Sections <fdl-invariant>` with translations requires
+special permission from their copyright holders, but you may include
+translations of some or all Invariant Sections in addition to the
+original versions of these Invariant Sections. You may include a
+translation of this License provided that you also include the original
+English version of this License. In case of a disagreement between the
+translation and the original English version of this License, the
+original English version will prevail.
+
+
+.. _fdl-section9:
+
+9. TERMINATION
+==============
+
+You may not copy, modify, sublicense, or distribute the
+:ref:`Document <fdl-document>` except as expressly provided for under
+this License. Any other attempt to copy, modify, sublicense or
+distribute the Document is void, and will automatically terminate your
+rights under this License. However, parties who have received copies, or
+rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.

+       -  The ioctl can't be handled because the device is busy. This is
+	  typically return while device is streaming, and an ioctl tried to
+	  change something that would affect the stream, or would require

+Introduction
+============
+
+Media devices increasingly handle multiple related functions. Many USB
+cameras include microphones, video capture hardware can also output
+video, or SoC camera interfaces also perform memory-to-memory operations
+similar to video codecs.
+
+Independent functions, even when implemented in the same hardware, can
+be modelled as separate devices. A USB camera with a microphone will be
+presented to userspace applications as V4L2 and ALSA capture devices.
+The devices' relationships (when using a webcam, end-users shouldn't
+have to manually select the associated USB microphone), while not made
+available directly to applications by the drivers, can usually be
+retrieved from sysfs.
+
+With more and more advanced SoC devices being introduced, the current
+approach will not scale. Device topologies are getting increasingly
+complex and can't always be represented by a tree structure. Hardware
+blocks are shared between different functions, creating dependencies
+between seemingly unrelated devices.
+
+Kernel abstraction APIs such as V4L2 and ALSA provide means for
+applications to access hardware parameters. As newer hardware expose an
+increasingly high number of those parameters, drivers need to guess what
+applications really require based on limited information, thereby
+implementing policies that belong to userspace.
+
+The media controller API aims at solving those problems.

+
+Media device model
+==================
+
+Discovering a device internal topology, and configuring it at runtime,
+is one of the goals of the media controller API. To achieve this,
+hardware devices and Linux Kernel interfaces are modelled as graph
+objects on an oriented graph. The object types that constitute the graph
+are:
+
+-  An **entity** is a basic media hardware or software building block.
+   It can correspond to a large variety of logical blocks such as
+   physical hardware devices (CMOS sensor for instance), logical
+   hardware devices (a building block in a System-on-Chip image
+   processing pipeline), DMA channels or physical connectors.
+
+-  An **interface** is a graph representation of a Linux Kernel
+   userspace API interface, like a device node or a sysfs file that
+   controls one or more entities in the graph.
+
+-  A **pad** is a data connection endpoint through which an entity can
+   interact with other entities. Data (not restricted to video) produced
+   by an entity flows from the entity's output to one or more entity
+   inputs. Pads should not be confused with physical pins at chip
+   boundaries.
+
+-  A **data link** is a point-to-point oriented connection between two
+   pads, either on the same entity or on different entities. Data flows
+   from a source pad to a sink pad.
+
+-  An **interface link** is a point-to-point bidirectional control
+   connection between a Linux Kernel interface and an entity.

+
+
+Description
+===========
+
+The :ref:`ioctl() <media-func-ioctl>` function manipulates media device
+parameters. The argument ``fd`` must be an open file descriptor.
+
+The ioctl ``request`` code specifies the media function to be called. It
+has encoded in it whether the argument is an input, output or read/write
+parameter, and the size of the argument ``argp`` in bytes.
+
+Macros and structures definitions specifying media ioctl requests and
+their parameters are located in the media.h header file. All media ioctl
+requests, their respective function and parameters are specified in
+:ref:`media-user-func`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+Request-specific error codes are listed in the individual requests
+descriptions.
+
+When an ioctl that takes an output or read/write parameter fails, the
+parameter remains unmodified.

+
+All media devices must support the ``MEDIA_IOC_DEVICE_INFO`` ioctl. To

+a struct :ref:`media_device_info <media-device-info>`. The driver
+fills the structure and returns the information to the application. The
+ioctl never fails.

+Description
+===========
+
+To query the attributes of an entity, applications set the id field of a
+struct :ref:`media_entity_desc <media-entity-desc>` structure and
+call the MEDIA_IOC_ENUM_ENTITIES ioctl with a pointer to this
+structure. The driver fills the rest of the structure or returns an

+
+.. _media-ent-id-flag-next:
+
+Entities can be enumerated by or'ing the id with the
+``MEDIA_ENT_ID_FLAG_NEXT`` flag. The driver will return information
+about the entity with the smallest id strictly larger than the requested
+one ('next entity'), or the ``EINVAL`` error code if there is none.
+
+Entity IDs can be non-contiguous. Applications must *not* try to
+enumerate entities by calling MEDIA_IOC_ENUM_ENTITIES with increasing

+Description
+===========
+
+To enumerate pads and/or links for a given entity, applications set the
+entity field of a struct :ref:`media_links_enum <media-links-enum>`
+structure and initialize the struct
+:ref:`media_pad_desc <media-pad-desc>` and struct

+the ``pads`` and ``links`` fields. They then call the
+MEDIA_IOC_ENUM_LINKS ioctl with a pointer to this structure.
+
+If the ``pads`` field is not NULL, the driver fills the ``pads`` array
+with information about the entity's pads. The array must have enough
+room to store all the entity's pads. The number of pads can be retrieved
+with :ref:`MEDIA_IOC_ENUM_ENTITIES`.
+
+If the ``links`` field is not NULL, the driver fills the ``links`` array
+with information about the entity's outbound links. The array must have
+enough room to store all the entity's outbound links. The number of
+outbound links can be retrieved with :ref:`MEDIA_IOC_ENUM_ENTITIES`.
+
+Only forward links that originate at one of the entity's source pads are

+Description
+===========
+
+The typical usage of this ioctl is to call it twice. On the first call,
+the structure defined at struct
+:ref:`media_v2_topology <media-v2-topology>` should be zeroed. At
+return, if no errors happen, this ioctl will return the
+``topology_version`` and the total number of entities, interfaces, pads
+and links.
+
+Before the second call, the userspace should allocate arrays to store
+the graph elements that are desired, putting the pointers to them at the
+ptr_entities, ptr_interfaces, ptr_links and/or ptr_pads, keeping the
+other values untouched.
+
+If the ``topology_version`` remains the same, the ioctl should fill the
+desired arrays with the media graph elements.

+    MEDIA_IOC_SETUP_LINK
+
+``argp``
+
+
+Description
+===========
+
+To change link properties applications fill a struct
+:ref:`media_link_desc <media-link-desc>` with link identification
+information (source and sink pad) and the new requested link flags. They
+then call the MEDIA_IOC_SETUP_LINK ioctl with a pointer to that
+structure.
+
+The only configurable property is the ``ENABLED`` link flag to
+enable/disable a link. Links marked with the ``IMMUTABLE`` link flag can
+not be enabled or disabled.
+
+Link configuration has no side effect on other links. If an enabled link
+at the sink pad prevents the link from being enabled, the driver returns
+with an ``EBUSY`` error code.
+
+Only links marked with the ``DYNAMIC`` link flag can be enabled/disabled
+while streaming media data. Attempting to enable or disable a streaming
+non-dynamic link will return an ``EBUSY`` error code.
+
+If the specified link can't be found the driver returns with an ``EINVAL``
+error code.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EINVAL
+    The struct :ref:`media_link_desc <media-link-desc>` references a
+    non-existing link, or the link is immutable and an attempt to modify
+    its configuration was made.

+************
+Introduction
+************
+
+The LIRC device interface is a bi-directional interface for transporting
+raw IR data between userspace and kernelspace. Fundamentally, it is just
+a chardev (/dev/lircX, for X = 0, 1, 2, ...), with a number of standard
+struct file_operations defined on it. With respect to transporting raw
+IR data to and fro, the essential fops are read, write and ioctl.
+
+Example dmesg output upon a driver registering w/LIRC:
+
+.. code-block:: none
+
+    $ dmesg |grep lirc_dev
+    lirc_dev: IR Remote Control driver registered, major 248
+    rc rc0: lirc_dev: driver ir-lirc-codec (mceusb) registered at minor = 0
+
+What you should see for a chardev:
+
+.. code-block:: none
+
+    $ ls -l /dev/lirc*
+    crw-rw---- 1 root root 248, 0 Jul 2 22:20 /dev/lirc0
+
+**********
+LIRC modes
+**********
+
+LIRC supports some modes of receiving and sending IR codes, as shown
+on the following table.
+
+.. _lirc-mode-mode2:
+
+``LIRC_MODE_MODE2``
+
+    The driver returns a sequence of pulse and space codes to userspace.
+
+    This mode is used only for IR receive.
+
+.. _lirc-mode-lirccode:
+
+``LIRC_MODE_LIRCCODE``
+
+    The IR signal is decoded internally by the receiver. The LIRC interface
+    returns the scancode as an integer value. This is the usual mode used
+    by several TV media cards.
+
+    This mode is used only for IR receive.
+
+.. _lirc-mode-pulse:
+
+``LIRC_MODE_PULSE``
+
+    On puse mode, a sequence of pulse/space integer values are written to the
+    lirc device using :Ref:`lirc-write`.
+
+    This mode is used only for IR send.

+
+
+Synopsis
+========
+
+.. code-block:: c
+
+    #include <unistd.h>
+
+
+.. cpp:function:: ssize_t read( int fd, void *buf, size_t count )
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by ``open()``.
+
+``buf``
+``count``
+
+
+Description
+===========
+
+:ref:`read() <lirc-read>` attempts to read up to ``count`` bytes from file
+descriptor ``fd`` into the buffer starting at ``buf``.  If ``count`` is zero,
+:ref:`read() <lirc-read>` returns zero and has no other results. If ``count``
+is greater than ``SSIZE_MAX``, the result is unspecified.
+
+The lircd userspace daemon reads raw IR data from the LIRC chardev. The
+exact format of the data depends on what modes a driver supports, and
+what mode has been selected. lircd obtains supported modes and sets the
+active mode via the ioctl interface, detailed at :ref:`lirc_func`.
+The generally preferred mode for receive is
+:ref:`LIRC_MODE_MODE2 <lirc-mode-mode2>`, in which packets containing an
+int value describing an IR signal are read from the chardev.
+
+See also
+`http://www.lirc.org/html/technical.html <http://www.lirc.org/html/technical.html>`__
+for more info.
+
+Return Value
+============
+
+On success, the number of bytes read is returned. It is not an error if
+this number is smaller than the number of bytes requested, or the amount
+of data required for one frame.  On error, -1 is returned, and the ``errno``
+variable is set appropriately.

+Introduction
+************
+
+Currently, most analog and digital devices have a Infrared input for
+remote controllers. Each manufacturer has their own type of control. It
+is not rare for the same manufacturer to ship different types of
+controls, depending on the device.
+
+A Remote Controller interface is mapped as a normal evdev/input
+interface, just like a keyboard or a mouse. So, it uses all ioctls
+already defined for any other input devices.
+
+However, remove controllers are more flexible than a normal input
+device, as the IR receiver (and/or transmitter) can be used in
+conjunction with a wide variety of different IR remotes.
+
+In order to allow flexibility, the Remote Controller subsystem allows
+controlling the RC-specific attributes via
+:ref:`the sysfs class nodes <remote_controllers_sysfs_nodes>`.

+scancodes which match the filter will wake the system from e.g. suspend
+to RAM or power off. Otherwise the write will fail with an error.

+
+Unfortunately, for several years, there was no effort to create uniform
+IR keycodes for different devices. This caused the same IR keyname to be
+mapped completely differently on different IR devices. This resulted
+that the same IR keyname to be mapped completely different on different
+IR's. Due to that, V4L2 API now specifies a standard for mapping Media
+keys on IR.
+
+This standard should be used by both V4L/DVB drivers and userspace
+applications
+
+The modules register the remote as keyboard within the linux input
+layer. This means that the IR key strokes will look like normal keyboard
+key strokes (if CONFIG_INPUT_KEYBOARD is enabled). Using the event
+devices (CONFIG_INPUT_EVDEV) it is possible for applications to access
+the remote via /dev/input/event devices.

+Application Priority
+********************
+
+When multiple applications share a device it may be desirable to assign
+them different priorities. Contrary to the traditional "rm -rf /" school
+of thought a video recording application could for example block other
+applications from changing video controls or switching the current TV
+channel. Another objective is to permit low priority applications
+working in background, which can be preempted by user controlled
+applications and automatically regain control of the device at a later
+time.
+
+Since these features cannot be implemented entirely in user space V4L2
+defines the :ref:`VIDIOC_G_PRIORITY <VIDIOC_G_PRIORITY>` and
+:ref:`VIDIOC_S_PRIORITY <VIDIOC_G_PRIORITY>` ioctls to request and
+query the access priority associate with a file descriptor. Opening a
+device assigns a medium priority, compatible with earlier versions of
+V4L2 and drivers not supporting these ioctls. Applications requiring a
+different priority will usually call :ref:`VIDIOC_S_PRIORITY
+<VIDIOC_G_PRIORITY>` after verifying the device with the
+:ref:`VIDIOC_QUERYCAP` ioctl.
+
+Ioctls changing driver properties, such as
+:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>`, return an ``EBUSY`` error code
+after another application obtained higher priority.

+************************
+Audio Inputs and Outputs
+************************
+
+Audio inputs and outputs are physical connectors of a device. Video
+capture devices have inputs, output devices have outputs, zero or more
+each. Radio devices have no audio inputs or outputs. They have exactly
+one tuner which in fact *is* an audio source, but this API associates
+tuners with video inputs or outputs only, and radio devices have none of
+these. [#f1]_ A connector on a TV card to loop back the received audio
+signal to a sound card is not considered an audio output.
+
+Audio and video inputs and outputs are associated. Selecting a video
+source also selects an audio source. This is most evident when the video
+and audio source is a tuner. Further audio connectors can combine with
+more than one video input or output. Assumed two composite video inputs
+and two audio inputs exist, there may be up to four valid combinations.
+The relation of video and audio connectors is defined in the
+``audioset`` field of the respective struct
+:ref:`v4l2_input <v4l2-input>` or struct
+:ref:`v4l2_output <v4l2-output>`, where each bit represents the index
+number, starting at zero, of one audio input or output.
+
+To learn about the number and attributes of the available inputs and
+outputs applications can enumerate them with the
+:ref:`VIDIOC_ENUMAUDIO` and
+:ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>` ioctl, respectively.
+The struct :ref:`v4l2_audio <v4l2-audio>` returned by the
+:ref:`VIDIOC_ENUMAUDIO` ioctl also contains signal
+:status information applicable when the current audio input is queried.
+
+The :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` and
+:ref:`VIDIOC_G_AUDOUT <VIDIOC_G_AUDOUT>` ioctls report the current
+audio input and output, respectively.
+
+.. note:: Note that, unlike :ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
+   :ref:`VIDIOC_G_OUTPUT <VIDIOC_G_OUTPUT>` these ioctls return a
+   structure as :ref:`VIDIOC_ENUMAUDIO` and
+   :ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>` do, not just an index.
+
+To select an audio input and change its properties applications call the
+:ref:`VIDIOC_S_AUDIO <VIDIOC_G_AUDIO>` ioctl. To select an audio
+output (which presently has no changeable properties) applications call
+the :ref:`VIDIOC_S_AUDOUT <VIDIOC_G_AUDOUT>` ioctl.
+
+Drivers must implement all audio input ioctls when the device has
+multiple selectable audio inputs, all audio output ioctls when the
+device has multiple selectable audio outputs. When the device has any
+audio inputs or outputs the driver must set the ``V4L2_CAP_AUDIO`` flag
+in the struct :ref:`v4l2_capability <v4l2-capability>` returned by
+the :ref:`VIDIOC_QUERYCAP` ioctl.
+
+
+Example: Information about the current audio input
+==================================================
+
+.. code-block:: c
+
+    struct v4l2_audio audio;
+
+    memset(&audio, 0, sizeof(audio));
+
+    if (-1 == ioctl(fd, VIDIOC_G_AUDIO, &audio)) {
+	perror("VIDIOC_G_AUDIO");
+	exit(EXIT_FAILURE);
+    }
+
+    printf("Current input: %s\\n", audio.name);
+
+
+Example: Switching to the first audio input
+===========================================
+
+.. code-block:: c
+
+    struct v4l2_audio audio;
+
+    memset(&audio, 0, sizeof(audio)); /* clear audio.mode, audio.reserved */
+
+    audio.index = 0;
+
+    if (-1 == ioctl(fd, VIDIOC_S_AUDIO, &audio)) {
+	perror("VIDIOC_S_AUDIO");
+	exit(EXIT_FAILURE);
+    }
+
+.. [#f1]
+   Actually struct :ref:`v4l2_audio <v4l2-audio>` ought to have a
+   ``tuner`` field like struct :ref:`v4l2_input <v4l2-input>`, not
+   only making the API more consistent but also permitting radio devices
+   with multiple tuners.

+Buffers
+*******
+
+A buffer contains data exchanged by application and driver using one of
+the Streaming I/O methods. In the multi-planar API, the data is held in
+planes, while the buffer structure acts as a container for the planes.
+Only pointers to buffers (planes) are exchanged, the data itself is not
+copied. These pointers, together with meta-information like timestamps
+or field parity, are stored in a struct :ref:`struct v4l2_buffer <v4l2-buffer>`,
+argument to the :ref:`VIDIOC_QUERYBUF`,
+:ref:`VIDIOC_QBUF` and
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. In the multi-planar API,
+some plane-specific members of struct :ref:`struct v4l2_buffer <v4l2-buffer>`,
+such as pointers and sizes for each plane, are stored in struct
+:ref:`struct v4l2_plane <v4l2-plane>` instead. In that case, struct
+:ref:`struct v4l2_buffer <v4l2-buffer>` contains an array of plane structures.
+
+Dequeued video buffers come with timestamps. The driver decides at which
+part of the frame and with which clock the timestamp is taken. Please
+see flags in the masks ``V4L2_BUF_FLAG_TIMESTAMP_MASK`` and
+``V4L2_BUF_FLAG_TSTAMP_SRC_MASK`` in :ref:`buffer-flags`. These flags
+are always valid and constant across all buffers during the whole video
+stream. Changes in these flags may take place as a side effect of
+:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` or
+:ref:`VIDIOC_S_OUTPUT <VIDIOC_G_OUTPUT>` however. The
+``V4L2_BUF_FLAG_TIMESTAMP_COPY`` timestamp type which is used by e.g. on
+mem-to-mem devices is an exception to the rule: the timestamp source
+flags are copied from the OUTPUT video buffer to the CAPTURE video
+buffer.

+	  when it refers to an output stream. If the application sets this
+	  to 0 for an output stream, then ``bytesused`` will be set to the
+	  size of the buffer (see the ``length`` field of this struct) by

+
+       -  ``V4L2_BUF_FLAG_MAPPED``
+
+       -  0x00000001
+
+       -  The buffer resides in device memory and has been mapped into the
+	  application's address space, see :ref:`mmap` for details.
+	  Drivers set or clear this flag when the
+	  :ref:`VIDIOC_QUERYBUF`,
+	  :ref:`VIDIOC_QBUF` or
+	  :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called. Set by the
+	  driver.
+
+    -  .. _`V4L2-BUF-FLAG-QUEUED`:
+
+       -  ``V4L2_BUF_FLAG_QUEUED``
+
+       -  0x00000002
+
+       -  Internally drivers maintain two buffer queues, an incoming and
+	  outgoing queue. When this flag is set, the buffer is currently on
+	  the incoming queue. It automatically moves to the outgoing queue
+	  after the buffer has been filled (capture devices) or displayed
+	  (output devices). Drivers set or clear this flag when the
+	  ``VIDIOC_QUERYBUF`` ioctl is called. After (successful) calling
+	  the ``VIDIOC_QBUF``\ ioctl it is always set and after
+	  ``VIDIOC_DQBUF`` always cleared.
+
+    -  .. _`V4L2-BUF-FLAG-DONE`:
+
+       -  ``V4L2_BUF_FLAG_DONE``
+
+       -  0x00000004
+
+       -  When this flag is set, the buffer is currently on the outgoing
+	  queue, ready to be dequeued from the driver. Drivers set or clear
+	  this flag when the ``VIDIOC_QUERYBUF`` ioctl is called. After
+	  calling the ``VIDIOC_QBUF`` or ``VIDIOC_DQBUF`` it is always
+	  cleared. Of course a buffer cannot be on both queues at the same
+	  time, the ``V4L2_BUF_FLAG_QUEUED`` and ``V4L2_BUF_FLAG_DONE`` flag
+	  are mutually exclusive. They can be both cleared however, then the
+	  buffer is in "dequeued" state, in the application domain so to
+	  say.
+
+    -  .. _`V4L2-BUF-FLAG-ERROR`:
+
+       -  ``V4L2_BUF_FLAG_ERROR``
+
+       -  0x00000040
+
+       -  When this flag is set, the buffer has been dequeued successfully,
+	  although the data might have been corrupted. This is recoverable,
+	  streaming may continue as normal and the buffer may be reused
+	  normally. Drivers set this flag when the ``VIDIOC_DQBUF`` ioctl is
+	  called.
+
+    -  .. _`V4L2-BUF-FLAG-KEYFRAME`:
+
+       -  ``V4L2_BUF_FLAG_KEYFRAME``
+
+       -  0x00000008
+
+       -  Drivers set or clear this flag when calling the ``VIDIOC_DQBUF``
+	  ioctl. It may be set by video capture devices when the buffer
+	  contains a compressed image which is a key frame (or field), i. e.
+	  can be decompressed on its own. Also known as an I-frame.
+	  Applications can set this bit when ``type`` refers to an output
+	  stream.
+
+    -  .. _`V4L2-BUF-FLAG-PFRAME`:
+
+       -  ``V4L2_BUF_FLAG_PFRAME``
+
+       -  0x00000010
+
+       -  Similar to ``V4L2_BUF_FLAG_KEYFRAME`` this flags predicted frames
+	  or fields which contain only differences to a previous key frame.
+	  Applications can set this bit when ``type`` refers to an output
+	  stream.
+
+    -  .. _`V4L2-BUF-FLAG-BFRAME`:
+
+       -  ``V4L2_BUF_FLAG_BFRAME``
+
+       -  0x00000020
+
+       -  Similar to ``V4L2_BUF_FLAG_KEYFRAME`` this flags a bi-directional
+	  predicted frame or field which contains only the differences
+	  between the current frame and both the preceding and following key
+	  frames to specify its content. Applications can set this bit when
+	  ``type`` refers to an output stream.
+
+    -  .. _`V4L2-BUF-FLAG-TIMECODE`:
+
+       -  ``V4L2_BUF_FLAG_TIMECODE``
+
+       -  0x00000100
+
+       -  The ``timecode`` field is valid. Drivers set or clear this flag
+	  when the ``VIDIOC_DQBUF`` ioctl is called. Applications can set
+	  this bit and the corresponding ``timecode`` structure when
+	  ``type`` refers to an output stream.
+
+    -  .. _`V4L2-BUF-FLAG-PREPARED`:
+
+       -  ``V4L2_BUF_FLAG_PREPARED``
+
+       -  0x00000400
+
+       -  The buffer has been prepared for I/O and can be queued by the
+	  application. Drivers set or clear this flag when the
+	  :ref:`VIDIOC_QUERYBUF`,
+	  :ref:`VIDIOC_PREPARE_BUF <VIDIOC_QBUF>`,
+	  :ref:`VIDIOC_QBUF` or
+	  :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called.
+
+    -  .. _`V4L2-BUF-FLAG-NO-CACHE-INVALIDATE`:
+
+       -  ``V4L2_BUF_FLAG_NO_CACHE_INVALIDATE``
+
+       -  0x00000800
+
+       -  Caches do not have to be invalidated for this buffer. Typically
+	  applications shall use this flag if the data captured in the
+	  buffer is not going to be touched by the CPU, instead the buffer
+	  will, probably, be passed on to a DMA-capable hardware unit for
+	  further processing or output.
+
+    -  .. _`V4L2-BUF-FLAG-NO-CACHE-CLEAN`:
+
+       -  ``V4L2_BUF_FLAG_NO_CACHE_CLEAN``
+
+       -  0x00001000
+
+       -  Caches do not have to be cleaned for this buffer. Typically
+	  applications shall use this flag for output buffers if the data in
+	  this buffer has not been created by the CPU but by some
+	  DMA-capable unit, in which case caches have not been used.
+
+    -  .. _`V4L2-BUF-FLAG-LAST`:
+
+       -  ``V4L2_BUF_FLAG_LAST``
+
+       -  0x00100000
+
+       -  Last buffer produced by the hardware. mem2mem codec drivers set
+	  this flag on the capture queue for the last buffer when the
+	  :ref:`VIDIOC_QUERYBUF` or
+	  :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl is called. Due to
+	  hardware limitations, the last buffer may be empty. In this case
+	  the driver will set the ``bytesused`` field to 0, regardless of
+	  the format. Any Any subsequent call to the
+	  :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl will not block anymore,
+	  but return an ``EPIPE`` error code.
+
+    -  .. _`V4L2-BUF-FLAG-TIMESTAMP-MASK`:
+
+       -  ``V4L2_BUF_FLAG_TIMESTAMP_MASK``
+
+       -  0x0000e000
+
+       -  Mask for timestamp types below. To test the timestamp type, mask
+	  out bits not belonging to timestamp type by performing a logical
+	  and operation with buffer flags and timestamp mask.
+
+    -  .. _`V4L2-BUF-FLAG-TIMESTAMP-UNKNOWN`:
+
+       -  ``V4L2_BUF_FLAG_TIMESTAMP_UNKNOWN``
+
+       -  0x00000000
+
+       -  Unknown timestamp type. This type is used by drivers before Linux
+	  3.9 and may be either monotonic (see below) or realtime (wall
+	  clock). Monotonic clock has been favoured in embedded systems
+	  whereas most of the drivers use the realtime clock. Either kinds
+	  of timestamps are available in user space via
+	  :c:func:`clock_gettime(2)` using clock IDs ``CLOCK_MONOTONIC``
+	  and ``CLOCK_REALTIME``, respectively.
+
+    -  .. _`V4L2-BUF-FLAG-TIMESTAMP-MONOTONIC`:
+
+       -  ``V4L2_BUF_FLAG_TIMESTAMP_MONOTONIC``
+
+       -  0x00002000
+
+       -  The buffer timestamp has been taken from the ``CLOCK_MONOTONIC``
+	  clock. To access the same clock outside V4L2, use
+	  :c:func:`clock_gettime(2)`.
+
+    -  .. _`V4L2-BUF-FLAG-TIMESTAMP-COPY`:
+
+       -  ``V4L2_BUF_FLAG_TIMESTAMP_COPY``
+
+       -  0x00004000
+
+       -  The CAPTURE buffer timestamp has been taken from the corresponding
+	  OUTPUT buffer. This flag applies only to mem2mem devices.
+
+    -  .. _`V4L2-BUF-FLAG-TSTAMP-SRC-MASK`:
+
+       -  ``V4L2_BUF_FLAG_TSTAMP_SRC_MASK``
+
+       -  0x00070000
+
+       -  Mask for timestamp sources below. The timestamp source defines the
+	  point of time the timestamp is taken in relation to the frame.
+	  Logical 'and' operation between the ``flags`` field and
+	  ``V4L2_BUF_FLAG_TSTAMP_SRC_MASK`` produces the value of the
+	  timestamp source. Applications must set the timestamp source when
+	  ``type`` refers to an output stream and
+	  ``V4L2_BUF_FLAG_TIMESTAMP_COPY`` is set.
+
+    -  .. _`V4L2-BUF-FLAG-TSTAMP-SRC-EOF`:
+
+       -  ``V4L2_BUF_FLAG_TSTAMP_SRC_EOF``
+
+       -  0x00000000
+
+       -  End Of Frame. The buffer timestamp has been taken when the last
+	  pixel of the frame has been received or the last pixel of the
+	  frame has been transmitted. In practice, software generated
+	  timestamps will typically be read from the clock a small amount of
+	  time after the last pixel has been received or transmitten,
+	  depending on the system and other activity in it.
+
+    -  .. _`V4L2-BUF-FLAG-TSTAMP-SRC-SOE`:
+
+       -  ``V4L2_BUF_FLAG_TSTAMP_SRC_SOE``
+
+       -  0x00010000
+
+       -  Start Of Exposure. The buffer timestamp has been taken when the
+	  exposure of the frame has begun. This is only valid for the
+	  ``V4L2_BUF_TYPE_VIDEO_CAPTURE`` buffer type.

+***********
+Colorspaces
+***********
+
+'Color' is a very complex concept and depends on physics, chemistry and
+biology. Just because you have three numbers that describe the 'red',
+'green' and 'blue' components of the color of a pixel does not mean that
+you can accurately display that color. A colorspace defines what it
+actually *means* to have an RGB value of e.g. (255, 0, 0). That is,
+which color should be reproduced on the screen in a perfectly calibrated
+environment.
+
+In order to do that we first need to have a good definition of color,
+i.e. some way to uniquely and unambiguously define a color so that
+someone else can reproduce it. Human color vision is trichromatic since
+the human eye has color receptors that are sensitive to three different
+wavelengths of light. Hence the need to use three numbers to describe
+color. Be glad you are not a mantis shrimp as those are sensitive to 12
+different wavelengths, so instead of RGB we would be using the
+ABCDEFGHIJKL colorspace...
+
+Color exists only in the eye and brain and is the result of how strongly
+color receptors are stimulated. This is based on the Spectral Power
+Distribution (SPD) which is a graph showing the intensity (radiant
+power) of the light at wavelengths covering the visible spectrum as it
+enters the eye. The science of colorimetry is about the relationship
+between the SPD and color as perceived by the human brain.
+
+Since the human eye has only three color receptors it is perfectly
+possible that different SPDs will result in the same stimulation of
+those receptors and are perceived as the same color, even though the SPD
+of the light is different.
+
+In the 1920s experiments were devised to determine the relationship
+between SPDs and the perceived color and that resulted in the CIE 1931
+standard that defines spectral weighting functions that model the
+perception of color. Specifically that standard defines functions that
+can take an SPD and calculate the stimulus for each color receptor.
+After some further mathematical transforms these stimuli are known as
+the *CIE XYZ tristimulus* values and these X, Y and Z values describe a
+color as perceived by a human unambiguously. These X, Y and Z values are
+all in the range [0…1].
+
+The Y value in the CIE XYZ colorspace corresponds to luminance. Often
+the CIE XYZ colorspace is transformed to the normalized CIE xyY
+colorspace:
+
+x = X / (X + Y + Z)
+
+y = Y / (X + Y + Z)
+
+The x and y values are the chromaticity coordinates and can be used to
+define a color without the luminance component Y. It is very confusing
+to have such similar names for these colorspaces. Just be aware that if
+colors are specified with lower case 'x' and 'y', then the CIE xyY
+colorspace is used. Upper case 'X' and 'Y' refer to the CIE XYZ
+colorspace. Also, y has nothing to do with luminance. Together x and y
+specify a color, and Y the luminance. That is really all you need to
+remember from a practical point of view. At the end of this section you
+will find reading resources that go into much more detail if you are
+interested.
+
+A monitor or TV will reproduce colors by emitting light at three
+different wavelengths, the combination of which will stimulate the color
+receptors in the eye and thus cause the perception of color.
+Historically these wavelengths were defined by the red, green and blue
+phosphors used in the displays. These *color primaries* are part of what
+defines a colorspace.
+
+Different display devices will have different primaries and some
+primaries are more suitable for some display technologies than others.
+This has resulted in a variety of colorspaces that are used for
+different display technologies or uses. To define a colorspace you need
+to define the three color primaries (these are typically defined as x, y
+chromaticity coordinates from the CIE xyY colorspace) but also the white
+reference: that is the color obtained when all three primaries are at
+maximum power. This determines the relative power or energy of the
+primaries. This is usually chosen to be close to daylight which has been
+defined as the CIE D65 Illuminant.
+
+To recapitulate: the CIE XYZ colorspace uniquely identifies colors.
+Other colorspaces are defined by three chromaticity coordinates defined
+in the CIE xyY colorspace. Based on those a 3x3 matrix can be
+constructed that transforms CIE XYZ colors to colors in the new
+colorspace.
+
+Both the CIE XYZ and the RGB colorspace that are derived from the
+specific chromaticity primaries are linear colorspaces. But neither the
+eye, nor display technology is linear. Doubling the values of all
+components in the linear colorspace will not be perceived as twice the
+intensity of the color. So each colorspace also defines a transfer
+function that takes a linear color component value and transforms it to
+the non-linear component value, which is a closer match to the
+non-linear performance of both the eye and displays. Linear component
+values are denoted RGB, non-linear are denoted as R'G'B'. In general
+colors used in graphics are all R'G'B', except in openGL which uses
+linear RGB. Special care should be taken when dealing with openGL to
+provide linear RGB colors or to use the built-in openGL support to apply
+the inverse transfer function.
+
+The final piece that defines a colorspace is a function that transforms
+non-linear R'G'B' to non-linear Y'CbCr. This function is determined by
+the so-called luma coefficients. There may be multiple possible Y'CbCr
+encodings allowed for the same colorspace. Many encodings of color
+prefer to use luma (Y') and chroma (CbCr) instead of R'G'B'. Since the
+human eye is more sensitive to differences in luminance than in color
+this encoding allows one to reduce the amount of color information
+compared to the luma data. Note that the luma (Y') is unrelated to the Y
+in the CIE XYZ colorspace. Also note that Y'CbCr is often called YCbCr
+or YUV even though these are strictly speaking wrong.
+
+Sometimes people confuse Y'CbCr as being a colorspace. This is not
+correct, it is just an encoding of an R'G'B' color into luma and chroma
+values. The underlying colorspace that is associated with the R'G'B'
+color is also associated with the Y'CbCr color.
+
+The final step is how the RGB, R'G'B' or Y'CbCr values are quantized.
+The CIE XYZ colorspace where X, Y and Z are in the range [0…1] describes
+all colors that humans can perceive, but the transform to another
+colorspace will produce colors that are outside the [0…1] range. Once
+clamped to the [0…1] range those colors can no longer be reproduced in
+that colorspace. This clamping is what reduces the extent or gamut of
+the colorspace. How the range of [0…1] is translated to integer values
+in the range of [0…255] (or higher, depending on the color depth) is
+called the quantization. This is *not* part of the colorspace
+definition. In practice RGB or R'G'B' values are full range, i.e. they
+use the full [0…255] range. Y'CbCr values on the other hand are limited
+range with Y' using [16…235] and Cb and Cr using [16…240].
+
+Unfortunately, in some cases limited range RGB is also used where the
+components use the range [16…235]. And full range Y'CbCr also exists
+using the [0…255] range.
+
+In order to correctly interpret a color you need to know the
+quantization range, whether it is R'G'B' or Y'CbCr, the used Y'CbCr
+encoding and the colorspace. From that information you can calculate the
+corresponding CIE XYZ color and map that again to whatever colorspace
+your display device uses.
+
+The colorspace definition itself consists of the three chromaticity
+primaries, the white reference chromaticity, a transfer function and the
+luma coefficients needed to transform R'G'B' to Y'CbCr. While some
+colorspace standards correctly define all four, quite often the
+colorspace standard only defines some, and you have to rely on other
+standards for the missing pieces. The fact that colorspaces are often a
+mix of different standards also led to very confusing naming conventions
+where the name of a standard was used to name a colorspace when in fact
+that standard was part of various other colorspaces as well.
+
+If you want to read more about colors and colorspaces, then the
+following resources are useful: :ref:`poynton` is a good practical
+book for video engineers, :ref:`colimg` has a much broader scope and
+describes many more aspects of color (physics, chemistry, biology,
+etc.). The
+`http://www.brucelindbloom.com <http://www.brucelindbloom.com>`__
+website is an excellent resource, especially with respect to the
+mathematics behind colorspace conversions. The wikipedia
+`CIE 1931 colorspace <http://en.wikipedia.org/wiki/CIE_1931_color_space#CIE_xy_chromaticity_diagram_and_the_CIE_xyY_color_space>`__
+article is also very useful.

+
+*************
+User Controls
+*************
+
+Devices typically have a number of user-settable controls such as
+brightness, saturation and so on, which would be presented to the user
+on a graphical user interface. But, different devices will have
+different controls available, and furthermore, the range of possible
+values, and the default value will vary from device to device. The
+control ioctls provide the information and a mechanism to create a nice
+user interface for these controls that will work correctly with any
+device.
+
+All controls are accessed using an ID value. V4L2 defines several IDs
+for specific purposes. Drivers can also implement their own custom
+controls using ``V4L2_CID_PRIVATE_BASE``  [#f1]_ and higher values. The
+pre-defined control IDs have the prefix ``V4L2_CID_``, and are listed in
+:ref:`control-id`. The ID is used when querying the attributes of a
+control, and when getting or setting the current value.
+
+Generally applications should present controls to the user without
+assumptions about their purpose. Each control comes with a name string
+the user is supposed to understand. When the purpose is non-intuitive
+the driver writer should provide a user manual, a user interface plug-in
+or a driver specific panel application. Predefined IDs were introduced
+to change a few controls programmatically, for example to mute a device
+during a channel switch.
+
+Drivers may enumerate different controls after switching the current
+video input or output, tuner or modulator, or audio input or output.
+Different in the sense of other bounds, another default and current
+value, step size or other menu items. A control with a certain *custom*
+ID can also change name and type.
+
+If a control is not applicable to the current configuration of the
+device (for example, it doesn't apply to the current video input)
+drivers set the ``V4L2_CTRL_FLAG_INACTIVE`` flag.
+
+Control values are stored globally, they do not change when switching
+except to stay within the reported bounds. They also do not change e. g.
+when the device is opened or closed, when the tuner radio frequency is
+changed or generally never without application request.
+
+V4L2 specifies an event mechanism to notify applications when controls
+change value (see
+:ref:`VIDIOC_SUBSCRIBE_EVENT`, event
+``V4L2_EVENT_CTRL``), panel applications might want to make use of that
+in order to always reflect the correct control value.
+
+All controls use machine endianness.
+
+
+.. _control-id:
+
+Control IDs
+===========
+
+``V4L2_CID_BASE``
+    First predefined ID, equal to ``V4L2_CID_BRIGHTNESS``.
+
+``V4L2_CID_USER_BASE``
+    Synonym of ``V4L2_CID_BASE``.
+
+``V4L2_CID_BRIGHTNESS`` ``(integer)``
+    Picture brightness, or more precisely, the black level.
+
+``V4L2_CID_CONTRAST`` ``(integer)``
+    Picture contrast or luma gain.
+
+``V4L2_CID_SATURATION`` ``(integer)``
+    Picture color saturation or chroma gain.
+
+``V4L2_CID_HUE`` ``(integer)``
+    Hue or color balance.
+
+``V4L2_CID_AUDIO_VOLUME`` ``(integer)``
+    Overall audio volume. Note some drivers also provide an OSS or ALSA
+    mixer interface.
+
+``V4L2_CID_AUDIO_BALANCE`` ``(integer)``
+    Audio stereo balance. Minimum corresponds to all the way left,
+    maximum to right.
+
+``V4L2_CID_AUDIO_BASS`` ``(integer)``
+    Audio bass adjustment.
+
+``V4L2_CID_AUDIO_TREBLE`` ``(integer)``
+    Audio treble adjustment.
+
+``V4L2_CID_AUDIO_MUTE`` ``(boolean)``
+    Mute audio, i. e. set the volume to zero, however without affecting
+    ``V4L2_CID_AUDIO_VOLUME``. Like ALSA drivers, V4L2 drivers must mute
+    at load time to avoid excessive noise. Actually the entire device
+    should be reset to a low power consumption state.
+
+``V4L2_CID_AUDIO_LOUDNESS`` ``(boolean)``
+    Loudness mode (bass boost).
+
+``V4L2_CID_BLACK_LEVEL`` ``(integer)``
+    Another name for brightness (not a synonym of
+    ``V4L2_CID_BRIGHTNESS``). This control is deprecated and should not
+    be used in new drivers and applications.
+
+``V4L2_CID_AUTO_WHITE_BALANCE`` ``(boolean)``
+    Automatic white balance (cameras).
+
+``V4L2_CID_DO_WHITE_BALANCE`` ``(button)``
+    This is an action control. When set (the value is ignored), the
+    device will do a white balance and then hold the current setting.
+    Contrast this with the boolean ``V4L2_CID_AUTO_WHITE_BALANCE``,
+    which, when activated, keeps adjusting the white balance.
+
+``V4L2_CID_RED_BALANCE`` ``(integer)``
+    Red chroma balance.
+
+``V4L2_CID_BLUE_BALANCE`` ``(integer)``
+    Blue chroma balance.
+
+``V4L2_CID_GAMMA`` ``(integer)``
+    Gamma adjust.
+
+``V4L2_CID_WHITENESS`` ``(integer)``
+    Whiteness for grey-scale devices. This is a synonym for
+    ``V4L2_CID_GAMMA``. This control is deprecated and should not be
+    used in new drivers and applications.
+
+``V4L2_CID_EXPOSURE`` ``(integer)``
+    Exposure (cameras). [Unit?]
+
+``V4L2_CID_AUTOGAIN`` ``(boolean)``
+    Automatic gain/exposure control.
+
+``V4L2_CID_GAIN`` ``(integer)``
+    Gain control.
+
+``V4L2_CID_HFLIP`` ``(boolean)``
+    Mirror the picture horizontally.
+
+``V4L2_CID_VFLIP`` ``(boolean)``
+    Mirror the picture vertically.
+
+.. _v4l2-power-line-frequency:
+
+``V4L2_CID_POWER_LINE_FREQUENCY`` ``(enum)``
+    Enables a power line frequency filter to avoid flicker. Possible
+    values for ``enum v4l2_power_line_frequency`` are:
+    ``V4L2_CID_POWER_LINE_FREQUENCY_DISABLED`` (0),
+    ``V4L2_CID_POWER_LINE_FREQUENCY_50HZ`` (1),
+    ``V4L2_CID_POWER_LINE_FREQUENCY_60HZ`` (2) and
+    ``V4L2_CID_POWER_LINE_FREQUENCY_AUTO`` (3).
+
+``V4L2_CID_HUE_AUTO`` ``(boolean)``
+    Enables automatic hue control by the device. The effect of setting
+    ``V4L2_CID_HUE`` while automatic hue control is enabled is
+    undefined, drivers should ignore such request.
+
+``V4L2_CID_WHITE_BALANCE_TEMPERATURE`` ``(integer)``
+    This control specifies the white balance settings as a color
+    temperature in Kelvin. A driver should have a minimum of 2800
+    (incandescent) to 6500 (daylight). For more information about color
+    temperature see
+    `Wikipedia <http://en.wikipedia.org/wiki/Color_temperature>`__.
+
+``V4L2_CID_SHARPNESS`` ``(integer)``
+    Adjusts the sharpness filters in a camera. The minimum value
+    disables the filters, higher values give a sharper picture.
+
+``V4L2_CID_BACKLIGHT_COMPENSATION`` ``(integer)``
+    Adjusts the backlight compensation in a camera. The minimum value
+    disables backlight compensation.
+
+``V4L2_CID_CHROMA_AGC`` ``(boolean)``
+    Chroma automatic gain control.
+
+``V4L2_CID_CHROMA_GAIN`` ``(integer)``
+    Adjusts the Chroma gain control (for use when chroma AGC is
+    disabled).
+
+``V4L2_CID_COLOR_KILLER`` ``(boolean)``
+    Enable the color killer (i. e. force a black & white image in case
+    of a weak video signal).
+
+.. _v4l2-colorfx:
+
+``V4L2_CID_COLORFX`` ``(enum)``
+    Selects a color effect. The following values are defined:
+
+
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0
+
+
+    -  .. row 1
+
+       -  ``V4L2_COLORFX_NONE``
+
+       -  Color effect is disabled.
+
+    -  .. row 2
+
+       -  ``V4L2_COLORFX_ANTIQUE``
+
+       -  An aging (old photo) effect.

+*************************************
+Image Cropping, Insertion and Scaling
+*************************************
+
+Some video capture devices can sample a subsection of the picture and
+shrink or enlarge it to an image of arbitrary size. We call these
+abilities cropping and scaling. Some video output devices can scale an
+image up or down and insert it at an arbitrary scan line and horizontal
+offset into a video signal.
+
+Applications can use the following API to select an area in the video
+signal, query the default area and the hardware limits.
+
+.. note:: Despite their name, the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>`,
+   :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_S_CROP
+   <VIDIOC_G_CROP>` ioctls apply to input as well as output devices.
+
+Scaling requires a source and a target. On a video capture or overlay
+device the source is the video signal, and the cropping ioctls determine
+the area actually sampled. The target are images read by the application
+or overlaid onto the graphics screen. Their size (and position for an
+overlay) is negotiated with the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
+and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls.
+
+On a video output device the source are the images passed in by the
+application, and their size is again negotiated with the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctls, or may be encoded in a compressed video stream. The target is
+the video signal, and the cropping ioctls determine the area where the
+images are inserted.
+
+Source and target rectangles are defined even if the device does not
+support scaling or the :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and
+:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctls. Their size (and position
+where applicable) will be fixed in this case.
+
+.. note:: All capture and output devices must support the
+   :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` ioctl such that applications
+   can determine if scaling takes place.
+
+
+Cropping Structures
+===================
+
+
+.. _crop-scale:
+
+.. figure::  crop_files/crop.*
+    :alt:    crop.pdf / crop.gif
+    :align:  center
+
+    Image Cropping, Insertion and Scaling
+
+    The cropping, insertion and scaling process
+
+
+
+For capture devices the coordinates of the top left corner, width and
+height of the area which can be sampled is given by the ``bounds``
+substructure of the struct :ref:`v4l2_cropcap <v4l2-cropcap>` returned
+by the :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` ioctl. To support a wide
+range of hardware this specification does not define an origin or units.
+However by convention drivers should horizontally count unscaled samples
+relative to 0H (the leading edge of the horizontal sync pulse, see
+:ref:`vbi-hsync`). Vertically ITU-R line numbers of the first field
+(see ITU R-525 line numbering for :ref:`525 lines <vbi-525>` and for
+:ref:`625 lines <vbi-625>`), multiplied by two if the driver
+can capture both fields.
+
+The top left corner, width and height of the source rectangle, that is
+the area actually sampled, is given by struct
+:ref:`v4l2_crop <v4l2-crop>` using the same coordinate system as
+struct :ref:`v4l2_cropcap <v4l2-cropcap>`. Applications can use the
+:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>`
+ioctls to get and set this rectangle. It must lie completely within the
+capture boundaries and the driver may further adjust the requested size
+and/or position according to hardware limitations.
+
+Each capture device has a default source rectangle, given by the
+``defrect`` substructure of struct
+:ref:`v4l2_cropcap <v4l2-cropcap>`. The center of this rectangle
+shall align with the center of the active picture area of the video
+signal, and cover what the driver writer considers the complete picture.
+Drivers shall reset the source rectangle to the default when the driver
+is first loaded, but not later.
+
+For output devices these structures and ioctls are used accordingly,
+defining the *target* rectangle where the images will be inserted into
+the video signal.
+
+
+Scaling Adjustments
+===================
+
+Video hardware can have various cropping, insertion and scaling
+limitations. It may only scale up or down, support only discrete scaling
+factors, or have different scaling abilities in horizontal and vertical
+direction. Also it may not support scaling at all. At the same time the
+struct :ref:`v4l2_crop <v4l2-crop>` rectangle may have to be aligned,
+and both the source and target rectangles may have arbitrary upper and
+lower size limits. In particular the maximum ``width`` and ``height`` in
+struct :ref:`v4l2_crop <v4l2-crop>` may be smaller than the struct
+:ref:`v4l2_cropcap <v4l2-cropcap>`. ``bounds`` area. Therefore, as
+usual, drivers are expected to adjust the requested parameters and
+return the actual values selected.
+
+Applications can change the source or the target rectangle first, as
+they may prefer a particular image size or a certain area in the video
+signal. If the driver has to adjust both to satisfy hardware
+limitations, the last requested rectangle shall take priority, and the
+driver should preferably adjust the opposite one. The
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl however shall not change
+the driver state and therefore only adjust the requested rectangle.
+
+Suppose scaling on a video capture device is restricted to a factor 1:1
+or 2:1 in either direction and the target image size must be a multiple
+of 16 × 16 pixels. The source cropping rectangle is set to defaults,
+which are also the upper limit in this example, of 640 × 400 pixels at
+offset 0, 0. An application requests an image size of 300 × 225 pixels,
+assuming video will be scaled down from the "full picture" accordingly.
+The driver sets the image size to the closest possible values 304 × 224,
+then chooses the cropping rectangle closest to the requested size, that
+is 608 × 224 (224 × 2:1 would exceed the limit 400). The offset 0, 0 is
+still valid, thus unmodified. Given the default cropping rectangle
+reported by :ref:`VIDIOC_CROPCAP <VIDIOC_CROPCAP>` the application can
+easily propose another offset to center the cropping rectangle.
+
+Now the application may insist on covering an area using a picture
+aspect ratio closer to the original request, so it asks for a cropping
+rectangle of 608 × 456 pixels. The present scaling factors limit
+cropping to 640 × 384, so the driver returns the cropping size 608 × 384
+and adjusts the image size to closest possible 304 × 192.
+
+
+Examples
+========
+
+Source and target rectangles shall remain unchanged across closing and
+reopening a device, such that piping data into or out of a device will
+work without special preparations. More advanced applications should
+ensure the parameters are suitable before starting I/O.
+
+.. note:: On the next two examples, a video capture device is assumed;
+   change ``V4L2_BUF_TYPE_VIDEO_CAPTURE`` for other types of device.

+***********************
+Video Capture Interface
+***********************
+
+Video capture devices sample an analog video signal and store the
+digitized images in memory. Today nearly all devices can capture at full
+25 or 30 frames/second. With this interface applications can control the
+capture process and move images from the driver into user space.
+
+Conventionally V4L2 video capture devices are accessed through character
+device special files named ``/dev/video`` and ``/dev/video0`` to
+``/dev/video63`` with major number 81 and minor numbers 0 to 63.
+``/dev/video`` is typically a symbolic link to the preferred video
+device.
+
+.. note:: The same device file names are used for video output devices.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the video capture interface set the
+``V4L2_CAP_VIDEO_CAPTURE`` or ``V4L2_CAP_VIDEO_CAPTURE_MPLANE`` flag in
+the ``capabilities`` field of struct
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. As secondary device
+functions they may also support the :ref:`video overlay <overlay>`
+(``V4L2_CAP_VIDEO_OVERLAY``) and the :ref:`raw VBI capture <raw-vbi>`
+(``V4L2_CAP_VBI_CAPTURE``) interface. At least one of the read/write or
+streaming I/O methods must be supported. Tuners and audio inputs are
+optional.
+
+
+Supplemental Functions
+======================
+
+Video capture devices shall support :ref:`audio input <audio>`,
+:ref:`tuner`, :ref:`controls <control>`,
+:ref:`cropping and scaling <crop>` and
+:ref:`streaming parameter <streaming-par>` ioctls as needed. The
+:ref:`video input <video>` and :ref:`video standard <standard>`
+ioctls must be supported by all video capture devices.
+
+
+Image Format Negotiation
+========================
+
+The result of a capture operation is determined by cropping and image
+format parameters. The former select an area of the video picture to
+capture, the latter how images are stored in memory, i. e. in RGB or YUV
+format, the number of bits per pixel or width and height. Together they
+also define how images are scaled in the process.
+
+As usual these parameters are *not* reset at :ref:`open() <func-open>`
+time to permit Unix tool chains, programming a device and then reading
+from it as if it was a plain file. Well written V4L2 applications ensure
+they really get what they want, including cropping and scaling.
+
+Cropping initialization at minimum requires to reset the parameters to
+defaults. An example is given in :ref:`crop`.
+
+To query the current image format applications set the ``type`` field of
+a struct :ref:`v4l2_format <v4l2-format>` to
+``V4L2_BUF_TYPE_VIDEO_CAPTURE`` or
+``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and call the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this
+structure. Drivers fill the struct
+:ref:`v4l2_pix_format <v4l2-pix-format>` ``pix`` or the struct
+:ref:`v4l2_pix_format_mplane <v4l2-pix-format-mplane>` ``pix_mp``
+member of the ``fmt`` union.
+
+To request different parameters applications set the ``type`` field of a
+struct :ref:`v4l2_format <v4l2-format>` as above and initialize all
+fields of the struct :ref:`v4l2_pix_format <v4l2-pix-format>`
+``vbi`` member of the ``fmt`` union, or better just modify the results
+of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl with a pointer to this structure. Drivers may adjust the
+parameters and finally return the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
+does.
+
+Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl
+can be used to learn about hardware limitations without disabling I/O or
+possibly time consuming hardware preparations.
+
+The contents of struct :ref:`v4l2_pix_format <v4l2-pix-format>` and
+struct :ref:`v4l2_pix_format_mplane <v4l2-pix-format-mplane>` are
+discussed in :ref:`pixfmt`. See also the specification of the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctls for
+details. Video capture devices must implement both the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`
+and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, even if :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ignores all
+requests and always returns default parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does.
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is optional.
+
+
+Reading Images
+==============
+
+A video capture device may support the ::ref:`read() function <func-read>`
+and/or streaming (:ref:`memory mapping <func-mmap>` or
+:ref:`user pointer <userp>`) I/O. See :ref:`io` for details.

+Codec Interface
+***************
+
+A V4L2 codec can compress, decompress, transform, or otherwise convert
+video data from one format into another format, in memory. Typically
+such devices are memory-to-memory devices (i.e. devices with the
+``V4L2_CAP_VIDEO_M2M`` or ``V4L2_CAP_VIDEO_M2M_MPLANE`` capability set).
+
+A memory-to-memory video node acts just like a normal video node, but it
+supports both output (sending frames from memory to the codec hardware)
+and capture (receiving the processed frames from the codec hardware into
+memory) stream I/O. An application will have to setup the stream I/O for
+both sides and finally call :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
+for both capture and output to start the codec.
+
+Video compression codecs use the MPEG controls to setup their codec
+parameters
+
+.. note:: The MPEG controls actually support many more codecs than
+   just MPEG. See :ref:`mpeg-controls`.
+
+Memory-to-memory devices can often be used as a shared resource: you can
+open the video node multiple times, each application setting up their
+own codec properties that are local to the file handle, and each can use
+it independently from the others. The driver will arbitrate access to
+the codec and reprogram it whenever another file handler gets access.
+This is different from the usual video node behavior where the video
+properties are global to the device (i.e. changing something through one
+file handle is visible through another file handle).

+Event Interface
+***************
+
+The V4L2 event interface provides a means for a user to get immediately
+notified on certain conditions taking place on a device. This might
+include start of frame or loss of signal events, for example. Changes in
+the value or state of a V4L2 control can also be reported through
+events.
+
+To receive events, the events the user is interested in first must be
+subscribed using the
+:ref:`VIDIOC_SUBSCRIBE_EVENT` ioctl. Once
+an event is subscribed, the events of subscribed types are dequeueable
+using the :ref:`VIDIOC_DQEVENT` ioctl. Events may be
+unsubscribed using VIDIOC_UNSUBSCRIBE_EVENT ioctl. The special event
+type V4L2_EVENT_ALL may be used to unsubscribe all the events the
+driver supports.
+
+The event subscriptions and event queues are specific to file handles.
+Subscribing an event on one file handle does not affect other file
+handles.
+
+The information on dequeueable events is obtained by using select or
+poll system calls on video devices. The V4L2 events use POLLPRI events
+on poll system call and exceptions on select system call.
+
+Starting with kernel 3.1 certain guarantees can be given with regards to
+events:
+
+1. Each subscribed event has its own internal dedicated event queue.
+   This means that flooding of one event type will not interfere with
+   other event types.
+
+2. If the internal event queue for a particular subscribed event becomes
+   full, then the oldest event in that queue will be dropped.
+
+3. Where applicable, certain event types can ensure that the payload of
+   the oldest event that is about to be dropped will be merged with the
+   payload of the next oldest event. Thus ensuring that no information
+   is lost, but only an intermediate step leading up to that
+   information. See the documentation for the event you want to
+   subscribe to whether this is applicable for that event or not.

+******************************
+Video Output Overlay Interface
+******************************
+
+**Also known as On-Screen Display (OSD)**
+
+Some video output devices can overlay a framebuffer image onto the
+outgoing video signal. Applications can set up such an overlay using
+this interface, which borrows structures and ioctls of the
+:ref:`Video Overlay <overlay>` interface.
+
+The OSD function is accessible through the same character special file
+as the :ref:`Video Output <capture>` function.
+
+.. note:: The default function of such a ``/dev/video`` device is video
+   capturing or output. The OSD function is only available after calling
+   the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the *Video Output Overlay* interface set the
+``V4L2_CAP_VIDEO_OUTPUT_OVERLAY`` flag in the ``capabilities`` field of
+struct :ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl.
+
+
+Framebuffer
+===========
+
+Contrary to the *Video Overlay* interface the framebuffer is normally
+implemented on the TV card and not the graphics card. On Linux it is
+accessible as a framebuffer device (``/dev/fbN``). Given a V4L2 device,
+applications can find the corresponding framebuffer device by calling
+the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` ioctl. It returns, amongst
+other information, the physical address of the framebuffer in the
+``base`` field of struct :ref:`v4l2_framebuffer <v4l2-framebuffer>`.
+The framebuffer device ioctl ``FBIOGET_FSCREENINFO`` returns the same
+address in the ``smem_start`` field of struct
+:c:type:`struct fb_fix_screeninfo`. The ``FBIOGET_FSCREENINFO``
+ioctl and struct :c:type:`struct fb_fix_screeninfo` are defined in
+the ``linux/fb.h`` header file.
+
+The width and height of the framebuffer depends on the current video
+standard. A V4L2 driver may reject attempts to change the video standard
+(or any other ioctl which would imply a framebuffer size change) with an
+``EBUSY`` error code until all applications closed the framebuffer device.
+
+Example: Finding a framebuffer device for OSD
+---------------------------------------------
+
+.. code-block:: c
+
+    #include <linux/fb.h>
+
+    struct v4l2_framebuffer fbuf;
+    unsigned int i;
+    int fb_fd;
+
+    if (-1 == ioctl(fd, VIDIOC_G_FBUF, &fbuf)) {
+	perror("VIDIOC_G_FBUF");
+	exit(EXIT_FAILURE);
+    }
+
+    for (i = 0; i < 30; i++) {
+	char dev_name[16];
+	struct fb_fix_screeninfo si;
+
+	snprintf(dev_name, sizeof(dev_name), "/dev/fb%u", i);
+
+	fb_fd = open(dev_name, O_RDWR);
+	if (-1 == fb_fd) {
+	    switch (errno) {
+	    case ENOENT: /* no such file */
+	    case ENXIO:  /* no driver */
+		continue;
+
+	    default:
+		perror("open");
+		exit(EXIT_FAILURE);
+	    }
+	}
+
+	if (0 == ioctl(fb_fd, FBIOGET_FSCREENINFO, &si)) {
+	    if (si.smem_start == (unsigned long)fbuf.base)
+		break;
+	} else {
+	    /* Apparently not a framebuffer device. */
+	}
+
+	close(fb_fd);
+	fb_fd = -1;
+    }
+
+    /* fb_fd is the file descriptor of the framebuffer device
+       for the video output overlay, or -1 if no device was found. */
+
+
+Overlay Window and Scaling
+==========================
+
+The overlay is controlled by source and target rectangles. The source
+rectangle selects a subsection of the framebuffer image to be overlaid,
+the target rectangle an area in the outgoing video signal where the
+image will appear. Drivers may or may not support scaling, and arbitrary
+sizes and positions of these rectangles. Further drivers may support any
+(or none) of the clipping/blending methods defined for the
+:ref:`Video Overlay <overlay>` interface.
+
+A struct :ref:`v4l2_window <v4l2-window>` defines the size of the
+source rectangle, its position in the framebuffer and the
+clipping/blending method to be used for the overlay. To get the current
+parameters applications set the ``type`` field of a struct
+:ref:`v4l2_format <v4l2-format>` to
+``V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY`` and call the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl. The driver fills the
+:ref:`struct v4l2_window <v4l2-window>` substructure named ``win``. It is not
+possible to retrieve a previously programmed clipping list or bitmap.
+
+To program the source rectangle applications set the ``type`` field of a
+struct :ref:`v4l2_format <v4l2-format>` to
+``V4L2_BUF_TYPE_VIDEO_OUTPUT_OVERLAY``, initialize the ``win``
+substructure and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+The driver adjusts the parameters against hardware limits and returns
+the actual parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`,
+the :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to learn
+about driver capabilities without actually changing driver state. Unlike
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` this also works after the overlay has been enabled.
+
+A struct :ref:`v4l2_crop <v4l2-crop>` defines the size and position
+of the target rectangle. The scaling factor of the overlay is implied by
+the width and height given in struct :ref:`v4l2_window <v4l2-window>`
+and struct :ref:`v4l2_crop <v4l2-crop>`. The cropping API applies to
+*Video Output* and *Video Output Overlay* devices in the same way as to
+*Video Capture* and *Video Overlay* devices, merely reversing the
+direction of the data flow. For more information see :ref:`crop`.
+
+
+Enabling Overlay
+================
+
+There is no V4L2 ioctl to enable or disable the overlay, however the
+framebuffer interface of the driver may support the ``FBIOBLANK`` ioctl.

+Video Overlay Interface
+***********************
+
+**Also known as Framebuffer Overlay or Previewing.**
+
+Video overlay devices have the ability to genlock (TV-)video into the
+(VGA-)video signal of a graphics card, or to store captured images
+directly in video memory of a graphics card, typically with clipping.
+This can be considerable more efficient than capturing images and
+displaying them by other means. In the old days when only nuclear power
+plants needed cooling towers this used to be the only way to put live
+video into a window.
+
+Video overlay devices are accessed through the same character special
+files as :ref:`video capture <capture>` devices.
+
+.. note:: The default function of a ``/dev/video`` device is video
+   capturing. The overlay function is only available after calling
+   the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+The driver may support simultaneous overlay and capturing using the
+read/write and streaming I/O methods. If so, operation at the nominal
+frame rate of the video standard is not guaranteed. Frames may be
+directed away from overlay to capture, or one field may be used for
+overlay and the other for capture if the capture parameters permit this.
+
+Applications should use different file descriptors for capturing and
+overlay. This must be supported by all drivers capable of simultaneous
+capturing and overlay. Optionally these drivers may also permit
+capturing and overlay with a single file descriptor for compatibility
+with V4L and earlier versions of V4L2. [#f1]_

+:ref:`tuner`, :ref:`controls <control>`,
+:ref:`cropping and scaling <crop>` and
+:ref:`streaming parameter <streaming-par>` ioctls as needed. The
+:ref:`video input <video>` and :ref:`video standard <standard>`
+ioctls must be supported by all video overlay devices.
+
+
+Setup
+=====
+
+Before overlay can commence applications must program the driver with
+frame buffer parameters, namely the address and size of the frame buffer
+and the image format, for example RGB 5:6:5. The
+:ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and
+:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctls are available to get and
+set these parameters, respectively. The :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl is
+privileged because it allows to set up DMA into physical memory,
+bypassing the memory protection mechanisms of the kernel. Only the
+superuser can change the frame buffer address and size. Users are not
+supposed to run TV applications as root or with SUID bit set. A small
+helper application with suitable privileges should query the graphics
+system and program the V4L2 driver at the appropriate time.
+
+Some devices add the video overlay to the output signal of the graphics
+card. In this case the frame buffer is not modified by the video device,
+and the frame buffer address and pixel format are not needed by the
+driver. The :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl is not privileged. An application
+can check for this type of device by calling the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
+ioctl.
+
+A driver may support any (or none) of five clipping/blending methods:
+
+1. Chroma-keying displays the overlaid image only where pixels in the
+   primary graphics surface assume a certain color.
+
+2. A bitmap can be specified where each bit corresponds to a pixel in
+   the overlaid image. When the bit is set, the corresponding video
+   pixel is displayed, otherwise a pixel of the graphics surface.
+
+3. A list of clipping rectangles can be specified. In these regions *no*
+   video is displayed, so the graphics surface can be seen here.
+
+4. The framebuffer has an alpha channel that can be used to clip or
+   blend the framebuffer with the video.
+
+5. A global alpha value can be specified to blend the framebuffer
+   contents with video images.
+
+When simultaneous capturing and overlay is supported and the hardware
+prohibits different image and frame buffer formats, the format requested
+first takes precedence. The attempt to capture
+(:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`) or overlay
+(:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`) may fail with an ``EBUSY`` error
+code or return accordingly modified parameters..
+
+
+Overlay Window
+==============
+
+The overlaid image is determined by cropping and overlay window
+parameters. The former select an area of the video picture to capture,
+the latter how images are overlaid and clipped. Cropping initialization
+at minimum requires to reset the parameters to defaults. An example is
+given in :ref:`crop`.
+
+The overlay window is described by a struct
+:ref:`v4l2_window <v4l2-window>`. It defines the size of the image,
+its position over the graphics surface and the clipping to be applied.
+To get the current parameters applications set the ``type`` field of a
+struct :ref:`v4l2_format <v4l2-format>` to
+``V4L2_BUF_TYPE_VIDEO_OVERLAY`` and call the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl. The driver fills the
+:ref:`struct v4l2_window <v4l2-window>` substructure named ``win``. It is not
+possible to retrieve a previously programmed clipping list or bitmap.
+
+To program the overlay window applications set the ``type`` field of a
+struct :ref:`v4l2_format <v4l2-format>` to
+``V4L2_BUF_TYPE_VIDEO_OVERLAY``, initialize the ``win`` substructure and
+call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. The driver
+adjusts the parameters against hardware limits and returns the actual
+parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Like :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, the
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to learn
+about driver capabilities without actually changing driver state. Unlike
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` this also works after the overlay has been enabled.
+
+The scaling factor of the overlaid image is implied by the width and
+height given in struct :ref:`v4l2_window <v4l2-window>` and the size
+of the cropping rectangle. For more information see :ref:`crop`.
+
+When simultaneous capturing and overlay is supported and the hardware
+prohibits different image and window sizes, the size requested first
+takes precedence. The attempt to capture or overlay as well
+(:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`) may fail with an ``EBUSY`` error
+code or return accordingly modified parameters.
+
+
+.. _v4l2-window:
+
+struct v4l2_window
+------------------
+
+``struct v4l2_rect w``
+    Size and position of the window relative to the top, left corner of
+    the frame buffer defined with
+    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. The window can extend the
+    frame buffer width and height, the ``x`` and ``y`` coordinates can
+    be negative, and it can lie completely outside the frame buffer. The
+    driver clips the window accordingly, or if that is not possible,
+    modifies its size and/or position.
+
+``enum v4l2_field field``
+    Applications set this field to determine which video field shall be
+    overlaid, typically one of ``V4L2_FIELD_ANY`` (0),
+    ``V4L2_FIELD_TOP``, ``V4L2_FIELD_BOTTOM`` or
+    ``V4L2_FIELD_INTERLACED``. Drivers may have to choose a different
+    field order and return the actual setting here.
+
+``__u32 chromakey``
+    When chroma-keying has been negotiated with
+    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` applications set this field
+    to the desired pixel value for the chroma key. The format is the
+    same as the pixel format of the framebuffer (struct
+    :ref:`v4l2_framebuffer <v4l2-framebuffer>` ``fmt.pixelformat``
+    field), with bytes in host order. E. g. for
+    :ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR32>` the value should
+    be 0xRRGGBB on a little endian, 0xBBGGRR on a big endian host.
+
+``struct v4l2_clip * clips``
+    When chroma-keying has *not* been negotiated and
+    :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` indicated this capability,
+    applications can set this field to point to an array of clipping
+    rectangles.
+
+    Like the window coordinates w, clipping rectangles are defined
+    relative to the top, left corner of the frame buffer. However
+    clipping rectangles must not extend the frame buffer width and
+    height, and they must not overlap. If possible applications
+    should merge adjacent rectangles. Whether this must create
+    x-y or y-x bands, or the order of rectangles, is not defined. When
+    clip lists are not supported the driver ignores this field. Its
+    contents after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+    are undefined.
+
+``__u32 clipcount``
+    When the application set the ``clips`` field, this field must
+    contain the number of clipping rectangles in the list. When clip
+    lists are not supported the driver ignores this field, its contents
+    after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` are undefined. When clip lists are
+    supported but no clipping is desired this field must be set to zero.
+
+``void * bitmap``
+    When chroma-keying has *not* been negotiated and
+    :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` indicated this capability,
+    applications can set this field to point to a clipping bit mask.
+
+It must be of the same size as the window, ``w.width`` and ``w.height``.
+Each bit corresponds to a pixel in the overlaid image, which is
+displayed only when the bit is *set*. Pixel coordinates translate to
+bits like:
+
+
+.. code-block:: c
+
+    ((__u8 *) bitmap)[w.width * y + x / 8] & (1 << (x & 7))
+
+where ``0`` ≤ x < ``w.width`` and ``0`` ≤ y <``w.height``. [#f2]_
+
+When a clipping bit mask is not supported the driver ignores this field,
+its contents after calling :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` are
+undefined. When a bit mask is supported but no clipping is desired this
+field must be set to ``NULL``.
+
+Applications need not create a clip list or bit mask. When they pass
+both, or despite negotiating chroma-keying, the results are undefined.
+Regardless of the chosen method, the clipping abilities of the hardware
+may be limited in quantity or quality. The results when these limits are
+exceeded are undefined. [#f3]_
+
+``__u8 global_alpha``
+    The global alpha value used to blend the framebuffer with video
+    images, if global alpha blending has been negotiated
+    (``V4L2_FBUF_FLAG_GLOBAL_ALPHA``, see
+    :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`,
+    :ref:`framebuffer-flags`).
+
+    .. note:: This field was added in Linux 2.6.23, extending the
+       structure. However the :ref:`VIDIOC_[G|S|TRY]_FMT <VIDIOC_G_FMT>`
+       ioctls, which take a pointer to a :ref:`v4l2_format <v4l2-format>`
+       parent structure with padding bytes at the end, are not affected.
+
+
+.. _v4l2-clip:
+
+struct v4l2_clip [#f4]_
+-----------------------
+
+``struct v4l2_rect c``
+    Coordinates of the clipping rectangle, relative to the top, left
+    corner of the frame buffer. Only window pixels *outside* all
+    clipping rectangles are displayed.
+
+``struct v4l2_clip * next``
+    Pointer to the next clipping rectangle, ``NULL`` when this is the last
+    rectangle. Drivers ignore this field, it cannot be used to pass a
+    linked list of clipping rectangles.
+
+
+.. _v4l2-rect:
+
+struct v4l2_rect
+----------------
+
+``__s32 left``
+    Horizontal offset of the top, left corner of the rectangle, in
+    pixels.
+
+``__s32 top``
+    Vertical offset of the top, left corner of the rectangle, in pixels.
+    Offsets increase to the right and down.
+
+``__u32 width``
+    Width of the rectangle, in pixels.
+
+``__u32 height``
+    Height of the rectangle, in pixels.
+
+
+Enabling Overlay
+================
+
+To start or stop the frame buffer overlay applications call the
+:ref:`VIDIOC_OVERLAY` ioctl.
+
+.. [#f1]
+   A common application of two file descriptors is the XFree86
+   :ref:`Xv/V4L <xvideo>` interface driver and a V4L2 application.
+   While the X server controls video overlay, the application can take
+   advantage of memory mapping and DMA.
+
+   In the opinion of the designers of this API, no driver writer taking
+   the efforts to support simultaneous capturing and overlay will
+   restrict this ability by requiring a single file descriptor, as in
+   V4L and earlier versions of V4L2. Making this optional means
+   applications depending on two file descriptors need backup routines
+   to be compatible with all drivers, which is considerable more work
+   than using two fds in applications which do not. Also two fd's fit
+   the general concept of one file descriptor for each logical stream.
+   Hence as a complexity trade-off drivers *must* support two file
+   descriptors and *may* support single fd operation.
+
+.. [#f2]
+   Should we require ``w.width`` to be a multiple of eight?
+
+.. [#f3]
+   When the image is written into frame buffer memory it will be
+   undesirable if the driver clips out less pixels than expected,
+   because the application and graphics system are not aware these
+   regions need to be refreshed. The driver should clip out more pixels
+   or not write the image at all.
+
+.. [#f4]
+   The X Window system defines "regions" which are vectors of ``struct
+   BoxRec { short x1, y1, x2, y2; }`` with ``width = x2 - x1`` and
+   ``height = y2 - y1``, so one cannot pass X11 clip lists directly.

+Radio Interface
+***************
+
+This interface is intended for AM and FM (analog) radio receivers and
+transmitters.
+
+Conventionally V4L2 radio devices are accessed through character device
+special files named ``/dev/radio`` and ``/dev/radio0`` to
+``/dev/radio63`` with major number 81 and minor numbers 64 to 127.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the radio interface set the ``V4L2_CAP_RADIO`` and
+``V4L2_CAP_TUNER`` or ``V4L2_CAP_MODULATOR`` flag in the
+``capabilities`` field of struct
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. Other combinations of
+capability flags are reserved for future extensions.
+
+
+Supplemental Functions
+======================
+
+Radio devices can support :ref:`controls <control>`, and must support
+the :ref:`tuner or modulator <tuner>` ioctls.
+
+They do not support the video input or output, audio input or output,
+video standard, cropping and scaling, compression and streaming
+parameter, or overlay ioctls. All other ioctls and I/O methods are
+reserved for future extensions.
+
+
+Programming
+===========
+
+Radio devices may have a couple audio controls (as discussed in
+:ref:`control`) such as a volume control, possibly custom controls.
+Further all radio devices have one tuner or modulator (these are
+discussed in :ref:`tuner`) with index number zero to select the radio
+frequency and to determine if a monaural or FM stereo program is
+received/emitted. Drivers switch automatically between AM and FM
+depending on the selected frequency. The
+:ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` or
+:ref:`VIDIOC_G_MODULATOR <VIDIOC_G_MODULATOR>` ioctl reports the
+supported frequency range.

+
+**********************
+Raw VBI Data Interface
+**********************
+
+VBI is an abbreviation of Vertical Blanking Interval, a gap in the
+sequence of lines of an analog video signal. During VBI no picture
+information is transmitted, allowing some time while the electron beam
+of a cathode ray tube TV returns to the top of the screen. Using an
+oscilloscope you will find here the vertical synchronization pulses and
+short data packages ASK modulated [#f1]_ onto the video signal. These are
+transmissions of services such as Teletext or Closed Caption.
+
+Subject of this interface type is raw VBI data, as sampled off a video
+signal, or to be added to a signal for output. The data format is
+similar to uncompressed video images, a number of lines times a number
+of samples per line, we call this a VBI image.
+
+Conventionally V4L2 VBI devices are accessed through character device
+special files named ``/dev/vbi`` and ``/dev/vbi0`` to ``/dev/vbi31``
+with major number 81 and minor numbers 224 to 255. ``/dev/vbi`` is
+typically a symbolic link to the preferred VBI device. This convention
+applies to both input and output devices.
+
+To address the problems of finding related video and VBI devices VBI
+capturing and output is also available as device function under
+``/dev/video``. To capture or output raw VBI data with these devices
+applications must call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+Accessed as ``/dev/vbi``, raw VBI capturing or output is the default
+device function.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the raw VBI capturing or output API set the
+``V4L2_CAP_VBI_CAPTURE`` or ``V4L2_CAP_VBI_OUTPUT`` flags, respectively,
+in the ``capabilities`` field of struct
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. At least one of the
+read/write, streaming or asynchronous I/O methods must be supported. VBI
+devices may or may not have a tuner or modulator.
+
+
+Supplemental Functions
+======================
+
+VBI devices shall support :ref:`video input or output <video>`,
+:ref:`tuner or modulator <tuner>`, and :ref:`controls <control>`
+ioctls as needed. The :ref:`video standard <standard>` ioctls provide
+information vital to program a VBI device, therefore must be supported.
+
+
+Raw VBI Format Negotiation
+==========================
+
+Raw VBI sampling abilities can vary, in particular the sampling
+frequency. To properly interpret the data V4L2 specifies an ioctl to
+query the sampling parameters. Moreover, to allow for some flexibility
+applications can also suggest different parameters.
+
+As usual these parameters are *not* reset at :ref:`open() <func-open>`
+time to permit Unix tool chains, programming a device and then reading
+from it as if it was a plain file. Well written V4L2 applications should
+always ensure they really get what they want, requesting reasonable
+parameters and then checking if the actual parameters are suitable.
+
+To query the current raw VBI capture parameters applications set the
+``type`` field of a struct :ref:`v4l2_format <v4l2-format>` to
+``V4L2_BUF_TYPE_VBI_CAPTURE`` or ``V4L2_BUF_TYPE_VBI_OUTPUT``, and call
+the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this
+structure. Drivers fill the struct
+:ref:`v4l2_vbi_format <v4l2-vbi-format>` ``vbi`` member of the
+``fmt`` union.
+
+To request different parameters applications set the ``type`` field of a
+struct :ref:`v4l2_format <v4l2-format>` as above and initialize all
+fields of the struct :ref:`v4l2_vbi_format <v4l2-vbi-format>`
+``vbi`` member of the ``fmt`` union, or better just modify the results
+of :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, and call the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl with a pointer to this structure. Drivers return an ``EINVAL`` error
+code only when the given parameters are ambiguous, otherwise they modify
+the parameters according to the hardware capabilities and return the
+actual parameters. When the driver allocates resources at this point, it
+may return an ``EBUSY`` error code to indicate the returned parameters are
+valid but the required resources are currently not available. That may
+happen for instance when the video and VBI areas to capture would
+overlap, or when the driver supports multiple opens and another process
+already requested VBI capturing or output. Anyway, applications must
+expect other resource allocation points which may return ``EBUSY``, at the
+:ref:`VIDIOC_STREAMON` ioctl and the first :ref:`read() <func-read>`
+, :ref:`write() <func-write>` and :ref:`select() <func-select>` calls.
+
+VBI devices must implement both the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl, even if :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ignores all requests
+and always returns default parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does.
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is optional.

+
+	  An application can set the first or second ``count`` value to zero
+	  if no data is required from the respective field; ``count``\ [1]
+	  if the scanning system is progressive, i. e. not interlaced. The

+	  (compare :ref:`field-order` ``V4L2_FIELD_SEQ_TB`` and
+	  ``V4L2_FIELD_SEQ_BT``, whether the top or bottom field is first in
+	  memory depends on the video standard). When this flag is set, the
+	  two fields are interlaced (cf. ``V4L2_FIELD_INTERLACED``). The
+	  first line of the first field followed by the first line of the
+	  second field, then the two second lines, and so on. Such a layout
+	  may be necessary when the hardware has been programmed to capture
+	  or output interlaced video images and is unable to separate the
+	  fields for VBI capturing at the same time. For simplicity setting
+	  this flag implies that both ``count`` values are equal and
+	  non-zero.

+
+Remember the VBI image format depends on the selected video standard,
+therefore the application must choose a new standard or query the
+current standard first. Attempts to read or write data ahead of format
+negotiation, or after switching the video standard which may invalidate
+the negotiated VBI parameters, should be refused by the driver. A format
+change during active I/O is not permitted.
+
+
+Reading and writing VBI images
+==============================
+
+To assure synchronization with the field number and easier
+implementation, the smallest unit of data passed at a time is one frame,
+consisting of two fields of VBI images immediately following in memory.
+
+The total size of a frame computes as follows:
+
+
+.. code-block:: c
+
+    (count[0] + count[1]) * samples_per_line * sample size in bytes
+
+The sample size is most likely always one byte, applications must check
+the ``sample_format`` field though, to function properly with other
+drivers.
+
+A VBI device may support :ref:`read/write <rw>` and/or streaming
+(:ref:`memory mapping <mmap>` or :ref:`user pointer <userp>`) I/O.
+The latter bears the possibility of synchronizing video and VBI data by
+using buffer timestamps.
+
+Remember the :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` ioctl and the
+first :ref:`read() <func-read>`, :ref:`write() <func-write>` and
+:ref:`select() <func-select>` call can be resource allocation
+points returning an ``EBUSY`` error code if the required hardware resources
+are temporarily unavailable, for example the device is already in use by
+another process.
+
+.. [#f1]
+   ASK: Amplitude-Shift Keying. A high signal level represents a '1'
+   bit, a low level a '0' bit.
+
+.. [#f2]
+   A few devices may be unable to sample VBI data at all but can extend
+   the video capture window to the VBI region.
+
+.. [#f3]
+   Most VBI services transmit on both fields, but some have different
+   semantics depending on the field number. These cannot be reliable
+   decoded or encoded when ``V4L2_VBI_UNSYNC`` is set.

+RDS Interface
+*************
+
+The Radio Data System transmits supplementary information in binary
+format, for example the station name or travel information, on an
+inaudible audio subcarrier of a radio program. This interface is aimed
+at devices capable of receiving and/or transmitting RDS information.
+
+For more information see the core RDS standard :ref:`iec62106` and the
+RBDS standard :ref:`nrsc4`.
+
+.. note:: Note that the RBDS standard as is used in the USA is almost
+   identical to the RDS standard. Any RDS decoder/encoder can also handle
+   RBDS. Only some of the fields have slightly different meanings. See the
+   RBDS standard for more information.
+
+The RBDS standard also specifies support for MMBS (Modified Mobile
+Search). This is a proprietary format which seems to be discontinued.
+The RDS interface does not support this format. Should support for MMBS
+(or the so-called 'E blocks' in general) be needed, then please contact
+the linux-media mailing list:
+`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the RDS capturing API set the
+``V4L2_CAP_RDS_CAPTURE`` flag in the ``capabilities`` field of struct
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. Any tuner that
+supports RDS will set the ``V4L2_TUNER_CAP_RDS`` flag in the
+``capability`` field of struct :ref:`v4l2_tuner <v4l2-tuner>`. If the
+driver only passes RDS blocks without interpreting the data the
+``V4L2_TUNER_CAP_RDS_BLOCK_IO`` flag has to be set, see
+:ref:`Reading RDS data <reading-rds-data>`. For future use the flag
+``V4L2_TUNER_CAP_RDS_CONTROLS`` has also been defined. However, a driver
+for a radio tuner with this capability does not yet exist, so if you are
+planning to write such a driver you should discuss this on the
+linux-media mailing list:
+`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
+
+Whether an RDS signal is present can be detected by looking at the
+``rxsubchans`` field of struct :ref:`v4l2_tuner <v4l2-tuner>`: the
+``V4L2_TUNER_SUB_RDS`` will be set if RDS data was detected.
+
+Devices supporting the RDS output API set the ``V4L2_CAP_RDS_OUTPUT``
+flag in the ``capabilities`` field of struct
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. Any modulator that
+supports RDS will set the ``V4L2_TUNER_CAP_RDS`` flag in the
+``capability`` field of struct
+:ref:`v4l2_modulator <v4l2-modulator>`. In order to enable the RDS
+transmission one must set the ``V4L2_TUNER_SUB_RDS`` bit in the
+``txsubchans`` field of struct
+:ref:`v4l2_modulator <v4l2-modulator>`. If the driver only passes RDS
+blocks without interpreting the data the ``V4L2_TUNER_CAP_RDS_BLOCK_IO``
+flag has to be set. If the tuner is capable of handling RDS entities
+like program identification codes and radio text, the flag
+``V4L2_TUNER_CAP_RDS_CONTROLS`` should be set, see
+:ref:`Writing RDS data <writing-rds-data>` and
+:ref:`FM Transmitter Control Reference <fm-tx-controls>`.

+**************************************
+Software Defined Radio Interface (SDR)
+**************************************
+
+SDR is an abbreviation of Software Defined Radio, the radio device which
+uses application software for modulation or demodulation. This interface
+is intended for controlling and data streaming of such devices.
+
+SDR devices are accessed through character device special files named
+``/dev/swradio0`` to ``/dev/swradio255`` with major number 81 and
+dynamically allocated minor numbers 0 to 255.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the SDR receiver interface set the
+``V4L2_CAP_SDR_CAPTURE`` and ``V4L2_CAP_TUNER`` flag in the
+``capabilities`` field of struct
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. That flag means the
+device has an Analog to Digital Converter (ADC), which is a mandatory
+element for the SDR receiver.
+
+Devices supporting the SDR transmitter interface set the
+``V4L2_CAP_SDR_OUTPUT`` and ``V4L2_CAP_MODULATOR`` flag in the
+``capabilities`` field of struct
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. That flag means the
+device has an Digital to Analog Converter (DAC), which is a mandatory
+element for the SDR transmitter.
+
+At least one of the read/write, streaming or asynchronous I/O methods
+must be supported.
+
+
+Supplemental Functions
+======================
+
+SDR devices can support :ref:`controls <control>`, and must support
+the :ref:`tuner` ioctls. Tuner ioctls are used for setting the
+ADC/DAC sampling rate (sampling frequency) and the possible radio
+frequency (RF).
+
+The ``V4L2_TUNER_SDR`` tuner type is used for setting SDR device ADC/DAC
+frequency, and the ``V4L2_TUNER_RF`` tuner type is used for setting
+radio frequency. The tuner index of the RF tuner (if any) must always
+follow the SDR tuner index. Normally the SDR tuner is #0 and the RF
+tuner is #1.
+
+The :ref:`VIDIOC_S_HW_FREQ_SEEK` ioctl is
+not supported.
+
+
+Data Format Negotiation
+=======================
+
+The SDR device uses the :ref:`format` ioctls to select the
+capture and output format. Both the sampling resolution and the data
+streaming format are bound to that selectable format. In addition to the
+basic :ref:`format` ioctls, the
+:ref:`VIDIOC_ENUM_FMT` ioctl must be supported as
+well.
+
+To use the :ref:`format` ioctls applications set the ``type``
+field of a struct :ref:`v4l2_format <v4l2-format>` to
+``V4L2_BUF_TYPE_SDR_CAPTURE`` or ``V4L2_BUF_TYPE_SDR_OUTPUT`` and use
+the struct :ref:`v4l2_sdr_format <v4l2-sdr-format>` ``sdr`` member
+of the ``fmt`` union as needed per the desired operation. Currently
+there is two fields, ``pixelformat`` and ``buffersize``, of struct
+struct :ref:`v4l2_sdr_format <v4l2-sdr-format>` which are used.
+Content of the ``pixelformat`` is V4L2 FourCC code of the data format.
+The ``buffersize`` field is maximum buffer size in bytes required for
+data transfer, set by the driver in order to inform application.

+*************************
+Sliced VBI Data Interface
+*************************
+
+VBI stands for Vertical Blanking Interval, a gap in the sequence of
+lines of an analog video signal. During VBI no picture information is
+transmitted, allowing some time while the electron beam of a cathode ray
+tube TV returns to the top of the screen.
+
+Sliced VBI devices use hardware to demodulate data transmitted in the
+VBI. V4L2 drivers shall *not* do this by software, see also the
+:ref:`raw VBI interface <raw-vbi>`. The data is passed as short
+packets of fixed size, covering one scan line each. The number of
+packets per video frame is variable.
+
+Sliced VBI capture and output devices are accessed through the same
+character special files as raw VBI devices. When a driver supports both
+interfaces, the default function of a ``/dev/vbi`` device is *raw* VBI
+capturing or output, and the sliced VBI function is only available after
+calling the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl as defined
+below. Likewise a ``/dev/video`` device may support the sliced VBI API,
+however the default function here is video capturing or output.
+Different file descriptors must be used to pass raw and sliced VBI data
+simultaneously, if this is supported by the driver.
+
+
+Querying Capabilities
+=====================
+
+Devices supporting the sliced VBI capturing or output API set the
+``V4L2_CAP_SLICED_VBI_CAPTURE`` or ``V4L2_CAP_SLICED_VBI_OUTPUT`` flag
+respectively, in the ``capabilities`` field of struct
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl. At least one of the
+read/write, streaming or asynchronous :ref:`I/O methods <io>` must be
+supported. Sliced VBI devices may have a tuner or modulator.
+
+
+Supplemental Functions
+======================
+
+Sliced VBI devices shall support :ref:`video input or output <video>`
+and :ref:`tuner or modulator <tuner>` ioctls if they have these
+capabilities, and they may support :ref:`control` ioctls.
+The :ref:`video standard <standard>` ioctls provide information vital
+to program a sliced VBI device, therefore must be supported.
+
+
+.. _sliced-vbi-format-negotitation:
+
+Sliced VBI Format Negotiation
+=============================
+
+To find out which data services are supported by the hardware
+applications can call the
+:ref:`VIDIOC_G_SLICED_VBI_CAP <VIDIOC_G_SLICED_VBI_CAP>` ioctl.
+All drivers implementing the sliced VBI interface must support this
+ioctl. The results may differ from those of the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl when the number of VBI
+lines the hardware can capture or output per frame, or the number of
+services it can identify on a given line are limited. For example on PAL
+line 16 the hardware may be able to look for a VPS or Teletext signal,
+but not both at the same time.
+
+To determine the currently selected services applications set the
+``type`` field of struct :ref:`v4l2_format <v4l2-format>` to
+``V4L2_BUF_TYPE_SLICED_VBI_CAPTURE`` or
+``V4L2_BUF_TYPE_SLICED_VBI_OUTPUT``, and the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl fills the ``fmt.sliced``
+member, a struct
+:ref:`v4l2_sliced_vbi_format <v4l2-sliced-vbi-format>`.
+
+Applications can request different parameters by initializing or
+modifying the ``fmt.sliced`` member and calling the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl with a pointer to the
+:ref:`struct v4l2_format <v4l2-format>` structure.
+
+The sliced VBI API is more complicated than the raw VBI API because the
+hardware must be told which VBI service to expect on each scan line. Not
+all services may be supported by the hardware on all lines (this is
+especially true for VBI output where Teletext is often unsupported and
+other services can only be inserted in one specific line). In many
+cases, however, it is sufficient to just set the ``service_set`` field
+to the required services and let the driver fill the ``service_lines``
+array according to hardware capabilities. Only if more precise control
+is needed should the programmer set the ``service_lines`` array
+explicitly.
+
+The :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl modifies the parameters
+according to hardware capabilities. When the driver allocates resources
+at this point, it may return an ``EBUSY`` error code if the required
+resources are temporarily unavailable. Other resource allocation points
+which may return ``EBUSY`` can be the
+:ref:`VIDIOC_STREAMON` ioctl and the first
+:ref:`read() <func-read>`, :ref:`write() <func-write>` and
+:ref:`select() <func-select>` call.

+of :ref:`struct v4l2_sliced_vbi_data <v4l2-sliced-vbi-data>` structures with one or
+more elements and a total size not exceeding ``io_size`` bytes. Likewise
+in streaming I/O mode one buffer of ``io_size`` bytes must contain data
+of one video frame. The ``id`` of unused
+:ref:`struct v4l2_sliced_vbi_data <v4l2-sliced-vbi-data>` elements must be zero.

+
+
+Packets are always passed in ascending line number order, without
+duplicate line numbers. The :ref:`write() <func-write>` function and
+the :ref:`VIDIOC_QBUF` ioctl must return an ``EINVAL``
+error code when applications violate this rule. They must also return an
+EINVAL error code when applications pass an incorrect field or line
+number, or a combination of ``field``, ``line`` and ``id`` which has not
+been negotiated with the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` or
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. When the line numbers are
+unknown the driver must pass the packets in transmitted order. The
+driver can insert empty packets with ``id`` set to zero anywhere in the
+packet array.
+
+To assure synchronization and to distinguish from frame dropping, when a
+captured frame does not carry any of the requested data services drivers
+must pass one or more empty packets. When an application fails to pass
+VBI data in time for output, the driver must output the last VPS and WSS
+packet again, and disable the output of Closed Caption and Teletext
+data, or output data which is ignored by Closed Caption and Teletext
+decoders.
+
+A sliced VBI device may support :ref:`read/write <rw>` and/or
+streaming (:ref:`memory mapping <mmap>` and/or
+:ref:`user pointer <userp>`) I/O. The latter bears the possibility of
+synchronizing video and VBI data by using buffer timestamps.
+
+
+Sliced VBI Data in MPEG Streams
+===============================
+
+If a device can produce an MPEG output stream, it may be capable of
+providing
+:ref:`negotiated sliced VBI services <sliced-vbi-format-negotitation>`
+as data embedded in the MPEG stream. Users or applications control this
+sliced VBI data insertion with the
+:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
+control.
+
+If the driver does not provide the
+:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
+control, or only allows that control to be set to
+:ref:`V4L2_MPEG_STREAM_VBI_FMT_NONE <v4l2-mpeg-stream-vbi-fmt>`,
+then the device cannot embed sliced VBI data in the MPEG stream.
+
+The
+:ref:`V4L2_CID_MPEG_STREAM_VBI_FMT <v4l2-mpeg-stream-vbi-fmt>`
+control does not implicitly set the device driver to capture nor cease
+capturing sliced VBI data. The control only indicates to embed sliced
+VBI data in the MPEG stream, if an application has negotiated sliced VBI
+service be captured.
+
+It may also be the case that a device can embed sliced VBI data in only
+certain types of MPEG streams: for example in an MPEG-2 PS but not an
+MPEG-2 TS. In this situation, if sliced VBI data insertion is requested,
+the sliced VBI data will be embedded in MPEG stream types when
+supported, and silently omitted from MPEG stream types where sliced VBI
+data insertion is not supported by the device.
+
+The following subsections specify the format of the embedded sliced VBI
+data.
+
+
+MPEG Stream Embedded, Sliced VBI Data Format: NONE
+--------------------------------------------------
+
+The
+:ref:`V4L2_MPEG_STREAM_VBI_FMT_NONE <v4l2-mpeg-stream-vbi-fmt>`
+embedded sliced VBI format shall be interpreted by drivers as a control
+to cease embedding sliced VBI data in MPEG streams. Neither the device
+nor driver shall insert "empty" embedded sliced VBI data packets in the
+MPEG stream when this format is set. No MPEG stream data structures are
+specified for this format.
+
+
+MPEG Stream Embedded, Sliced VBI Data Format: IVTV
+--------------------------------------------------
+
+The
+:ref:`V4L2_MPEG_STREAM_VBI_FMT_IVTV <v4l2-mpeg-stream-vbi-fmt>`
+embedded sliced VBI format, when supported, indicates to the driver to
+embed up to 36 lines of sliced VBI data per frame in an MPEG-2 *Private
+Stream 1 PES* packet encapsulated in an MPEG-2 *Program Pack* in the
+MPEG stream.
+
+*Historical context*: This format specification originates from a
+custom, embedded, sliced VBI data format used by the ``ivtv`` driver.
+This format has already been informally specified in the kernel sources
+in the file ``Documentation/video4linux/cx2341x/README.vbi`` . The
+maximum size of the payload and other aspects of this format are driven
+by the CX23415 MPEG decoder's capabilities and limitations with respect
+to extracting, decoding, and displaying sliced VBI data embedded within
+an MPEG stream.
+
+This format's use is *not* exclusive to the ``ivtv`` driver *nor*
+exclusive to CX2341x devices, as the sliced VBI data packet insertion
+into the MPEG stream is implemented in driver software. At least the
+``cx18`` driver provides sliced VBI data insertion into an MPEG-2 PS in
+this format as well.
+
+The following definitions specify the payload of the MPEG-2 *Private
+Stream 1 PES* packets that contain sliced VBI data when
+:ref:`V4L2_MPEG_STREAM_VBI_FMT_IVTV <v4l2-mpeg-stream-vbi-fmt>`
+is set. (The MPEG-2 *Private Stream 1 PES* packet header and
+encapsulating MPEG-2 *Program Pack* header are not detailed here. Please
+refer to the MPEG-2 specifications for details on those packet headers.)
+
+The payload of the MPEG-2 *Private Stream 1 PES* packets that contain
+sliced VBI data is specified by struct
+:ref:`v4l2_mpeg_vbi_fmt_ivtv <v4l2-mpeg-vbi-fmt-ivtv>`. The
+payload is variable length, depending on the actual number of lines of
+sliced VBI data present in a video frame. The payload may be padded at
+the end with unspecified fill bytes to align the end of the payload to a
+4-byte boundary. The payload shall never exceed 1552 bytes (2 fields
+with 18 lines/field with 43 bytes of data/line and a 4 byte magic
+number).

+********************
+Sub-device Interface
+********************
+
+The complex nature of V4L2 devices, where hardware is often made of
+several integrated circuits that need to interact with each other in a
+controlled way, leads to complex V4L2 drivers. The drivers usually
+reflect the hardware model in software, and model the different hardware
+components as software blocks called sub-devices.
+
+V4L2 sub-devices are usually kernel-only objects. If the V4L2 driver
+implements the media device API, they will automatically inherit from
+media entities. Applications will be able to enumerate the sub-devices
+and discover the hardware topology using the media entities, pads and
+links enumeration API.
+
+In addition to make sub-devices discoverable, drivers can also choose to
+make them directly configurable by applications. When both the
+sub-device driver and the V4L2 device driver support this, sub-devices
+will feature a character device node on which ioctls can be called to
+
+-  query, read and write sub-devices controls
+
+-  subscribe and unsubscribe to events and retrieve them
+
+-  negotiate image formats on individual pads
+
+Sub-device character device nodes, conventionally named
+``/dev/v4l-subdev*``, use major number 81.
+
+
+Controls
+========
+
+Most V4L2 controls are implemented by sub-device hardware. Drivers
+usually merge all controls and expose them through video device nodes.
+Applications can control all sub-devices through a single interface.
+
+Complex devices sometimes implement the same control in different pieces
+of hardware. This situation is common in embedded platforms, where both
+sensors and image processing hardware implement identical functions,
+such as contrast adjustment, white balance or faulty pixels correction.
+As the V4L2 controls API doesn't support several identical controls in a
+single device, all but one of the identical controls are hidden.
+
+Applications can access those hidden controls through the sub-device
+node with the V4L2 control API described in :ref:`control`. The ioctls
+behave identically as when issued on V4L2 device nodes, with the
+exception that they deal only with controls implemented in the
+sub-device.
+
+Depending on the driver, those controls might also be exposed through
+one (or several) V4L2 device nodes.
+
+
+Events
+======
+
+V4L2 sub-devices can notify applications of events as described in
+:ref:`event`. The API behaves identically as when used on V4L2 device
+nodes, with the exception that it only deals with events generated by
+the sub-device. Depending on the driver, those events might also be
+reported on one (or several) V4L2 device nodes.
+
+
+.. _pad-level-formats:
+
+Pad-level Formats
+=================
+
+.. warning::
+
+    Pad-level formats are only applicable to very complex devices that
+    need to expose low-level format configuration to user space. Generic
+    V4L2 applications do *not* need to use the API described in this
+    section.
+
+.. note::
+
+    For the purpose of this section, the term *format* means the
+    combination of media bus data format, frame width and frame height.
+
+Image formats are typically negotiated on video capture and output
+devices using the format and
+:ref:`selection <VIDIOC_SUBDEV_G_SELECTION>` ioctls. The driver is
+responsible for configuring every block in the video pipeline according
+to the requested format at the pipeline input and/or output.
+
+For complex devices, such as often found in embedded systems, identical
+image sizes at the output of a pipeline can be achieved using different
+hardware configurations. One such example is shown on
+:ref:`pipeline-scaling`, where image scaling can be performed on both
+the video sensor and the host image processing hardware.
+
+
+.. _pipeline-scaling:
+
+.. figure::  dev-subdev_files/pipeline.*
+    :alt:    pipeline.pdf / pipeline.png
+    :align:  center
+
+    Image Format Negotiation on Pipelines
+
+    High quality and high speed pipeline configuration
+
+
+
+The sensor scaler is usually of less quality than the host scaler, but
+scaling on the sensor is required to achieve higher frame rates.
+Depending on the use case (quality vs. speed), the pipeline must be
+configured differently. Applications need to configure the formats at
+every point in the pipeline explicitly.
+
+Drivers that implement the :ref:`media API <media-controller-intro>`
+can expose pad-level image format configuration to applications. When
+they do, applications can use the
+:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` and
+:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctls. to
+negotiate formats on a per-pad basis.
+
+Applications are responsible for configuring coherent parameters on the
+whole pipeline and making sure that connected pads have compatible
+formats. The pipeline is checked for formats mismatch at
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` time, and an ``EPIPE`` error
+code is then returned if the configuration is invalid.
+
+Pad-level image format configuration support can be tested by calling
+the :ref:`VIDIOC_SUBDEV_G_FMT` ioctl on pad
+0. If the driver returns an ``EINVAL`` error code pad-level format
+configuration is not supported by the sub-device.
+
+
+Format Negotiation
+------------------
+
+Acceptable formats on pads can (and usually do) depend on a number of
+external parameters, such as formats on other pads, active links, or
+even controls. Finding a combination of formats on all pads in a video
+pipeline, acceptable to both application and driver, can't rely on
+formats enumeration only. A format negotiation mechanism is required.
+
+Central to the format negotiation mechanism are the get/set format
+operations. When called with the ``which`` argument set to
+:ref:`V4L2_SUBDEV_FORMAT_TRY <VIDIOC_SUBDEV_G_FMT>`, the
+:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` and
+:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctls operate on
+a set of formats parameters that are not connected to the hardware
+configuration. Modifying those 'try' formats leaves the device state
+untouched (this applies to both the software state stored in the driver
+and the hardware state stored in the device itself).
+
+While not kept as part of the device state, try formats are stored in
+the sub-device file handles. A
+:ref:`VIDIOC_SUBDEV_G_FMT <VIDIOC_SUBDEV_G_FMT>` call will return
+the last try format set *on the same sub-device file handle*. Several
+applications querying the same sub-device at the same time will thus not
+interact with each other.
+
+To find out whether a particular format is supported by the device,
+applications use the
+:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctl. Drivers
+verify and, if needed, change the requested ``format`` based on device
+requirements and return the possibly modified value. Applications can
+then choose to try a different format or accept the returned value and
+continue.
+
+Formats returned by the driver during a negotiation iteration are
+guaranteed to be supported by the device. In particular, drivers
+guarantee that a returned format will not be further changed if passed
+to an :ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` call as-is
+(as long as external parameters, such as formats on other pads or links'
+configuration are not changed).
+
+Drivers automatically propagate formats inside sub-devices. When a try
+or active format is set on a pad, corresponding formats on other pads of
+the same sub-device can be modified by the driver. Drivers are free to
+modify formats as required by the device. However, they should comply
+with the following rules when possible:
+
+-  Formats should be propagated from sink pads to source pads. Modifying
+   a format on a source pad should not modify the format on any sink
+   pad.
+
+-  Sub-devices that scale frames using variable scaling factors should
+   reset the scale factors to default values when sink pads formats are
+   modified. If the 1:1 scaling ratio is supported, this means that
+   source pads formats should be reset to the sink pads formats.
+
+Formats are not propagated across links, as that would involve
+propagating them from one sub-device file handle to another.
+Applications must then take care to configure both ends of every link
+explicitly with compatible formats. Identical formats on the two ends of
+a link are guaranteed to be compatible. Drivers are free to accept
+different formats matching device requirements as being compatible.

+
+1. Initial state. The sensor source pad format is set to its native 3MP
+   size and V4L2_MBUS_FMT_SGRBG8_1X8 media bus code. Formats on the
+   host frontend and scaler sink and source pads have the default
+   values, as well as the compose rectangle on the scaler's sink pad.
+
+2. The application configures the frontend sink pad format's size to
+   2048x1536 and its media bus code to V4L2_MBUS_FMT_SGRBG_1X8. The
+   driver propagates the format to the frontend source pad.
+
+3. The application configures the scaler sink pad format's size to
+   2046x1534 and the media bus code to V4L2_MBUS_FMT_SGRBG_1X8 to
+   match the frontend source size and media bus code. The media bus code
+   on the sink pad is set to V4L2_MBUS_FMT_SGRBG_1X8. The driver
+   propagates the size to the compose selection rectangle on the
+   scaler's sink pad, and the format to the scaler source pad.
+
+4. The application configures the size of the compose selection
+   rectangle of the scaler's sink pad 1280x960. The driver propagates
+   the size to the scaler's source pad format.
+
+When satisfied with the try results, applications can set the active
+formats by setting the ``which`` argument to
+``V4L2_SUBDEV_FORMAT_ACTIVE``. Active formats are changed exactly as try
+formats by drivers. To avoid modifying the hardware state during format
+negotiation, applications should negotiate try formats first and then
+modify the active settings using the try formats returned during the
+last negotiation iteration. This guarantees that the active format will
+be applied as-is by the driver without being modified.
+
+
+.. _v4l2-subdev-selections:
+
+Selections: cropping, scaling and composition
+---------------------------------------------
+
+Many sub-devices support cropping frames on their input or output pads
+(or possible even on both). Cropping is used to select the area of
+interest in an image, typically on an image sensor or a video decoder.
+It can also be used as part of digital zoom implementations to select
+the area of the image that will be scaled up.
+
+Crop settings are defined by a crop rectangle and represented in a
+struct :ref:`v4l2_rect <v4l2-rect>` by the coordinates of the top
+left corner and the rectangle size. Both the coordinates and sizes are
+expressed in pixels.
+
+As for pad formats, drivers store try and active rectangles for the
+selection targets :ref:`v4l2-selections-common`.
+
+On sink pads, cropping is applied relative to the current pad format.
+The pad format represents the image size as received by the sub-device
+from the previous block in the pipeline, and the crop rectangle
+represents the sub-image that will be transmitted further inside the
+sub-device for processing.
+
+The scaling operation changes the size of the image by scaling it to new
+dimensions. The scaling ratio isn't specified explicitly, but is implied
+from the original and scaled image sizes. Both sizes are represented by
+struct :ref:`v4l2_rect <v4l2-rect>`.
+
+Scaling support is optional. When supported by a subdev, the crop
+rectangle on the subdev's sink pad is scaled to the size configured
+using the
+:ref:`VIDIOC_SUBDEV_S_SELECTION <VIDIOC_SUBDEV_G_SELECTION>` IOCTL
+using ``V4L2_SEL_TGT_COMPOSE`` selection target on the same pad. If the
+subdev supports scaling but not composing, the top and left values are
+not used and must always be set to zero.
+
+On source pads, cropping is similar to sink pads, with the exception
+that the source size from which the cropping is performed, is the
+COMPOSE rectangle on the sink pad. In both sink and source pads, the
+crop rectangle must be entirely contained inside the source image size
+for the crop operation.
+
+The drivers should always use the closest possible rectangle the user
+requests on all selection targets, unless specifically told otherwise.
+``V4L2_SEL_FLAG_GE`` and ``V4L2_SEL_FLAG_LE`` flags may be used to round
+the image size either up or down. :ref:`v4l2-selection-flags`
+
+
+Types of selection targets
+--------------------------
+
+
+Actual targets
+^^^^^^^^^^^^^^
+
+Actual targets (without a postfix) reflect the actual hardware
+configuration at any point of time. There is a BOUNDS target
+corresponding to every actual target.
+
+
+BOUNDS targets
+^^^^^^^^^^^^^^
+
+BOUNDS targets is the smallest rectangle that contains all valid actual
+rectangles. It may not be possible to set the actual rectangle as large
+as the BOUNDS rectangle, however. This may be because e.g. a sensor's
+pixel array is not rectangular but cross-shaped or round. The maximum
+size may also be smaller than the BOUNDS rectangle.
+
+
+Order of configuration and format propagation
+---------------------------------------------
+
+Inside subdevs, the order of image processing steps will always be from
+the sink pad towards the source pad. This is also reflected in the order
+in which the configuration must be performed by the user: the changes
+made will be propagated to any subsequent stages. If this behaviour is
+not desired, the user must set ``V4L2_SEL_FLAG_KEEP_CONFIG`` flag. This
+flag causes no propagation of the changes are allowed in any
+circumstances. This may also cause the accessed rectangle to be adjusted
+by the driver, depending on the properties of the underlying hardware.
+
+The coordinates to a step always refer to the actual size of the
+previous step. The exception to this rule is the source compose
+rectangle, which refers to the sink compose bounds rectangle --- if it
+is supported by the hardware.
+
+1. Sink pad format. The user configures the sink pad format. This format
+   defines the parameters of the image the entity receives through the
+   pad for further processing.
+
+2. Sink pad actual crop selection. The sink pad crop defines the crop
+   performed to the sink pad format.
+
+3. Sink pad actual compose selection. The size of the sink pad compose
+   rectangle defines the scaling ratio compared to the size of the sink
+   pad crop rectangle. The location of the compose rectangle specifies
+   the location of the actual sink compose rectangle in the sink compose
+   bounds rectangle.
+
+4. Source pad actual crop selection. Crop on the source pad defines crop
+   performed to the image in the sink compose bounds rectangle.
+
+5. Source pad format. The source pad format defines the output pixel
+   format of the subdev, as well as the other parameters with the
+   exception of the image width and height. Width and height are defined
+   by the size of the source pad actual crop selection.
+
+Accessing any of the above rectangles not supported by the subdev will
+return ``EINVAL``. Any rectangle referring to a previous unsupported
+rectangle coordinates will instead refer to the previous supported
+rectangle. For example, if sink crop is not supported, the compose
+selection will refer to the sink pad format dimensions instead.

+
+    **Figure 4.5. Image processing in subdevs: simple crop example**
+
+In the above example, the subdev supports cropping on its sink pad. To
+configure it, the user sets the media bus format on the subdev's sink
+pad. Now the actual crop rectangle can be set on the sink pad --- the
+location and size of this rectangle reflect the location and size of a
+rectangle to be cropped from the sink format. The size of the sink crop
+rectangle will also be the size of the format of the subdev's source
+pad.

+
+    **Figure 4.6. Image processing in subdevs: scaling with multiple sources**
+
+In this example, the subdev is capable of first cropping, then scaling
+and finally cropping for two source pads individually from the resulting
+scaled image. The location of the scaled image in the cropped image is
+ignored in sink compose target. Both of the locations of the source crop
+rectangles refer to the sink scaling rectangle, independently cropping
+an area at location specified by the source crop rectangle from it.

+
+    **Figure 4.7. Image processing in subdevs: scaling and composition with multiple sinks and sources**
+
+The subdev driver supports two sink pads and two source pads. The images
+from both of the sink pads are individually cropped, then scaled and
+further composed on the composition bounds rectangle. From that, two
+independent streams are cropped and sent out of the subdev from the
+source pads.

+******************
+Teletext Interface
+******************
+
+This interface was aimed at devices receiving and demodulating Teletext
+data [:ref:`ets300706`, :ref:`itu653`], evaluating the Teletext
+packages and storing formatted pages in cache memory. Such devices are
+usually implemented as microcontrollers with serial interface
+(I:sup:`2`\ C) and could be found on old TV cards, dedicated Teletext
+decoding cards and home-brew devices connected to the PC parallel port.
+
+The Teletext API was designed by Martin Buck. It was defined in the
+kernel header file ``linux/videotext.h``, the specification is available
+from
+`ftp://ftp.gwdg.de/pub/linux/misc/videotext/ <ftp://ftp.gwdg.de/pub/linux/misc/videotext/>`__.
+(Videotext is the name of the German public television Teletext
+service.)
+
+Eventually the Teletext API was integrated into the V4L API with
+character device file names ``/dev/vtx0`` to ``/dev/vtx31``, device
+major number 81, minor numbers 192 to 223.
+
+However, teletext decoders were quickly replaced by more generic VBI
+demodulators and those dedicated teletext decoders no longer exist. For
+many years the vtx devices were still around, even though nobody used
+them. So the decision was made to finally remove support for the
+Teletext API in kernel 2.6.37.
+
+Modern devices all use the :ref:`raw <raw-vbi>` or
+:ref:`sliced` VBI API.

+Differences between V4L and V4L2
+********************************
+
+The Video For Linux API was first introduced in Linux 2.1 to unify and
+replace various TV and radio device related interfaces, developed
+independently by driver writers in prior years. Starting with Linux 2.5
+the much improved V4L2 API replaces the V4L API. The support for the old
+V4L calls were removed from Kernel, but the library :ref:`libv4l`
+supports the conversion of a V4L API system call into a V4L2 one.
+
+
+Opening and Closing Devices
+===========================
+
+For compatibility reasons the character device file names recommended
+for V4L2 video capture, overlay, radio and raw vbi capture devices did
+not change from those used by V4L. They are listed in :ref:`devices`
+and below in :ref:`v4l-dev`.
+
+The teletext devices (minor range 192-223) have been removed in V4L2 and
+no longer exist. There is no hardware available anymore for handling
+pure teletext. Instead raw or sliced VBI is used.
+
+The V4L ``videodev`` module automatically assigns minor numbers to
+drivers in load order, depending on the registered device type. We
+recommend that V4L2 drivers by default register devices with the same
+numbers, but the system administrator can assign arbitrary minor numbers
+using driver module options. The major device number remains 81.

+
+
+V4L prohibits (or used to prohibit) multiple opens of a device file.
+V4L2 drivers *may* support multiple opens, see :ref:`open` for details
+and consequences.
+
+V4L drivers respond to V4L2 ioctls with an ``EINVAL`` error code.
+
+
+Querying Capabilities
+=====================
+
+The V4L ``VIDIOCGCAP`` ioctl is equivalent to V4L2's
+:ref:`VIDIOC_QUERYCAP`.
+
+The ``name`` field in struct :c:type:`struct video_capability` became
+``card`` in struct :ref:`v4l2_capability <v4l2-capability>`, ``type``
+was replaced by ``capabilities``. Note V4L2 does not distinguish between
+device types like this, better think of basic video input, video output
+and radio devices supporting a set of related functions like video
+capturing, video overlay and VBI capturing. See :ref:`open` for an
+introduction.

+
+       -  ``-``
+
+       -  See above.
+
+
+The ``audios`` field was replaced by ``capabilities`` flag
+``V4L2_CAP_AUDIO``, indicating *if* the device has any audio inputs or
+outputs. To determine their number applications can enumerate audio
+inputs with the :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` ioctl. The
+audio ioctls are described in :ref:`audio`.
+
+The ``maxwidth``, ``maxheight``, ``minwidth`` and ``minheight`` fields
+were removed. Calling the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` or
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl with the desired
+dimensions returns the closest size possible, taking into account the
+current video standard, cropping and scaling limitations.
+
+
+Video Sources
+=============
+
+V4L provides the ``VIDIOCGCHAN`` and ``VIDIOCSCHAN`` ioctl using struct
+:c:type:`struct video_channel` to enumerate the video inputs of a V4L
+device. The equivalent V4L2 ioctls are
+:ref:`VIDIOC_ENUMINPUT`,
+:ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
+:ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` using struct
+:ref:`v4l2_input <v4l2-input>` as discussed in :ref:`video`.
+
+The ``channel`` field counting inputs was renamed to ``index``, the
+video input types were renamed as follows:
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+
+    -  .. row 1
+
+       -  struct :c:type:`struct video_channel` ``type``
+
+       -  struct :ref:`v4l2_input <v4l2-input>` ``type``
+
+    -  .. row 2
+
+       -  ``VIDEO_TYPE_TV``
+
+       -  ``V4L2_INPUT_TYPE_TUNER``
+
+    -  .. row 3
+
+       -  ``VIDEO_TYPE_CAMERA``
+
+       -  ``V4L2_INPUT_TYPE_CAMERA``
+
+
+Unlike the ``tuners`` field expressing the number of tuners of this
+input, V4L2 assumes each video input is connected to at most one tuner.
+However a tuner can have more than one input, i. e. RF connectors, and a
+device can have multiple tuners. The index number of the tuner
+associated with the input, if any, is stored in field ``tuner`` of
+struct :ref:`v4l2_input <v4l2-input>`. Enumeration of tuners is
+discussed in :ref:`tuner`.
+
+The redundant ``VIDEO_VC_TUNER`` flag was dropped. Video inputs
+associated with a tuner are of type ``V4L2_INPUT_TYPE_TUNER``. The
+``VIDEO_VC_AUDIO`` flag was replaced by the ``audioset`` field. V4L2
+considers devices with up to 32 audio inputs. Each set bit in the
+``audioset`` field represents one audio input this video input combines
+with. For information about audio inputs and how to switch between them
+see :ref:`audio`.
+
+The ``norm`` field describing the supported video standards was replaced
+by ``std``. The V4L specification mentions a flag ``VIDEO_VC_NORM``
+indicating whether the standard can be changed. This flag was a later
+addition together with the ``norm`` field and has been removed in the
+meantime. V4L2 has a similar, albeit more comprehensive approach to
+video standards, see :ref:`standard` for more information.
+
+
+Tuning
+======
+
+The V4L ``VIDIOCGTUNER`` and ``VIDIOCSTUNER`` ioctl and struct
+:c:type:`struct video_tuner` can be used to enumerate the tuners of a
+V4L TV or radio device. The equivalent V4L2 ioctls are
+:ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` and
+:ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` using struct
+:ref:`v4l2_tuner <v4l2-tuner>`. Tuners are covered in :ref:`tuner`.
+
+The ``tuner`` field counting tuners was renamed to ``index``. The fields
+``name``, ``rangelow`` and ``rangehigh`` remained unchanged.
+
+The ``VIDEO_TUNER_PAL``, ``VIDEO_TUNER_NTSC`` and ``VIDEO_TUNER_SECAM``
+flags indicating the supported video standards were dropped. This
+information is now contained in the associated struct
+:ref:`v4l2_input <v4l2-input>`. No replacement exists for the
+``VIDEO_TUNER_NORM`` flag indicating whether the video standard can be
+switched. The ``mode`` field to select a different video standard was
+replaced by a whole new set of ioctls and structures described in
+:ref:`standard`. Due to its ubiquity it should be mentioned the BTTV
+driver supports several standards in addition to the regular
+``VIDEO_MODE_PAL`` (0), ``VIDEO_MODE_NTSC``, ``VIDEO_MODE_SECAM`` and
+``VIDEO_MODE_AUTO`` (3). Namely N/PAL Argentina, M/PAL, N/PAL, and NTSC
+Japan with numbers 3-6 (sic).
+
+The ``VIDEO_TUNER_STEREO_ON`` flag indicating stereo reception became
+``V4L2_TUNER_SUB_STEREO`` in field ``rxsubchans``. This field also
+permits the detection of monaural and bilingual audio, see the
+definition of struct :ref:`v4l2_tuner <v4l2-tuner>` for details.
+Presently no replacement exists for the ``VIDEO_TUNER_RDS_ON`` and
+``VIDEO_TUNER_MBS_ON`` flags.
+
+The ``VIDEO_TUNER_LOW`` flag was renamed to ``V4L2_TUNER_CAP_LOW`` in
+the struct :ref:`v4l2_tuner <v4l2-tuner>` ``capability`` field.
+
+The ``VIDIOCGFREQ`` and ``VIDIOCSFREQ`` ioctl to change the tuner
+frequency where renamed to
+:ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>`. They take a pointer
+to a struct :ref:`v4l2_frequency <v4l2-frequency>` instead of an
+unsigned long integer.
+
+

+
+Image Properties
+================
+
+V4L2 has no equivalent of the ``VIDIOCGPICT`` and ``VIDIOCSPICT`` ioctl
+and struct :c:type:`struct video_picture`. The following fields where
+replaced by V4L2 controls accessible with the
+:ref:`VIDIOC_QUERYCTRL`,
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls:
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0

+    -  .. row 1

+
+       -  ``whiteness``
+
+       -  ``V4L2_CID_WHITENESS``
+
+
+The V4L picture controls are assumed to range from 0 to 65535 with no
+particular reset value. The V4L2 API permits arbitrary limits and
+defaults which can be queried with the
+:ref:`VIDIOC_QUERYCTRL` ioctl. For general
+information about controls see :ref:`control`.
+
+The ``depth`` (average number of bits per pixel) of a video image is
+implied by the selected image format. V4L2 does not explicitly provide
+such information assuming applications recognizing the format are aware
+of the image depth and others need not know. The ``palette`` field moved
+into the struct :ref:`v4l2_pix_format <v4l2-pix-format>`:

+
+
+V4L2 image formats are defined in :ref:`pixfmt`. The image format can
+be selected with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+
+Audio
+=====
+
+The ``VIDIOCGAUDIO`` and ``VIDIOCSAUDIO`` ioctl and struct
+:c:type:`struct video_audio` are used to enumerate the audio inputs
+of a V4L device. The equivalent V4L2 ioctls are
+:ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` and
+:ref:`VIDIOC_S_AUDIO <VIDIOC_G_AUDIO>` using struct
+:ref:`v4l2_audio <v4l2-audio>` as discussed in :ref:`audio`.
+
+The ``audio`` "channel number" field counting audio inputs was renamed
+to ``index``.
+
+On ``VIDIOCSAUDIO`` the ``mode`` field selects *one* of the
+``VIDEO_SOUND_MONO``, ``VIDEO_SOUND_STEREO``, ``VIDEO_SOUND_LANG1`` or
+``VIDEO_SOUND_LANG2`` audio demodulation modes. When the current audio
+standard is BTSC ``VIDEO_SOUND_LANG2`` refers to SAP and
+``VIDEO_SOUND_LANG1`` is meaningless. Also undocumented in the V4L
+specification, there is no way to query the selected mode. On
+``VIDIOCGAUDIO`` the driver returns the *actually received* audio
+programmes in this field. In the V4L2 API this information is stored in
+the struct :ref:`v4l2_tuner <v4l2-tuner>` ``rxsubchans`` and
+``audmode`` fields, respectively. See :ref:`tuner` for more
+information on tuners. Related to audio modes struct
+:ref:`v4l2_audio <v4l2-audio>` also reports if this is a mono or
+stereo input, regardless if the source is a tuner.
+
+The following fields where replaced by V4L2 controls accessible with the
+:ref:`VIDIOC_QUERYCTRL`,
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls:
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+
+    -  .. row 1
+
+       -  struct :c:type:`struct video_audio`
+
+       -  V4L2 Control ID
+
+    -  .. row 2
+
+       -  ``volume``
+
+       -  ``V4L2_CID_AUDIO_VOLUME``
+
+    -  .. row 3
+
+       -  ``bass``
+
+       -  ``V4L2_CID_AUDIO_BASS``
+
+    -  .. row 4
+
+       -  ``treble``
+
+       -  ``V4L2_CID_AUDIO_TREBLE``
+
+    -  .. row 5
+
+       -  ``balance``
+
+       -  ``V4L2_CID_AUDIO_BALANCE``
+
+
+To determine which of these controls are supported by a driver V4L
+provides the ``flags`` ``VIDEO_AUDIO_VOLUME``, ``VIDEO_AUDIO_BASS``,
+``VIDEO_AUDIO_TREBLE`` and ``VIDEO_AUDIO_BALANCE``. In the V4L2 API the
+:ref:`VIDIOC_QUERYCTRL` ioctl reports if the
+respective control is supported. Accordingly the ``VIDEO_AUDIO_MUTABLE``
+and ``VIDEO_AUDIO_MUTE`` flags where replaced by the boolean
+``V4L2_CID_AUDIO_MUTE`` control.
+
+All V4L2 controls have a ``step`` attribute replacing the struct
+:c:type:`struct video_audio` ``step`` field. The V4L audio controls
+are assumed to range from 0 to 65535 with no particular reset value. The
+V4L2 API permits arbitrary limits and defaults which can be queried with
+the :ref:`VIDIOC_QUERYCTRL` ioctl. For general
+information about controls see :ref:`control`.
+
+
+Frame Buffer Overlay
+====================
+
+The V4L2 ioctls equivalent to ``VIDIOCGFBUF`` and ``VIDIOCSFBUF`` are
+:ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and
+:ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. The ``base`` field of struct
+:c:type:`struct video_buffer` remained unchanged, except V4L2 defines
+a flag to indicate non-destructive overlays instead of a ``NULL``
+pointer. All other fields moved into the struct
+:ref:`v4l2_pix_format <v4l2-pix-format>` ``fmt`` substructure of
+struct :ref:`v4l2_framebuffer <v4l2-framebuffer>`. The ``depth``
+field was replaced by ``pixelformat``. See :ref:`pixfmt-rgb` for a
+list of RGB formats and their respective color depths.
+
+Instead of the special ioctls ``VIDIOCGWIN`` and ``VIDIOCSWIN`` V4L2
+uses the general-purpose data format negotiation ioctls
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`. They take a pointer to a struct
+:ref:`v4l2_format <v4l2-format>` as argument. Here the ``win`` member
+of the ``fmt`` union is used, a struct
+:ref:`v4l2_window <v4l2-window>`.
+
+The ``x``, ``y``, ``width`` and ``height`` fields of struct
+:c:type:`struct video_window` moved into struct
+:ref:`v4l2_rect <v4l2-rect>` substructure ``w`` of struct
+:c:type:`struct v4l2_window`. The ``chromakey``, ``clips``, and
+``clipcount`` fields remained unchanged. Struct
+:c:type:`struct video_clip` was renamed to struct
+:ref:`v4l2_clip <v4l2-clip>`, also containing a struct
+:c:type:`struct v4l2_rect`, but the semantics are still the same.
+
+The ``VIDEO_WINDOW_INTERLACE`` flag was dropped. Instead applications
+must set the ``field`` field to ``V4L2_FIELD_ANY`` or
+``V4L2_FIELD_INTERLACED``. The ``VIDEO_WINDOW_CHROMAKEY`` flag moved
+into struct :ref:`v4l2_framebuffer <v4l2-framebuffer>`, under the new
+name ``V4L2_FBUF_FLAG_CHROMAKEY``.
+
+In V4L, storing a bitmap pointer in ``clips`` and setting ``clipcount``
+to ``VIDEO_CLIP_BITMAP`` (-1) requests bitmap clipping, using a fixed
+size bitmap of 1024 × 625 bits. Struct :c:type:`struct v4l2_window`
+has a separate ``bitmap`` pointer field for this purpose and the bitmap
+size is determined by ``w.width`` and ``w.height``.
+
+The ``VIDIOCCAPTURE`` ioctl to enable or disable overlay was renamed to
+:ref:`VIDIOC_OVERLAY`.
+
+
+Cropping
+========
+
+To capture only a subsection of the full picture V4L defines the
+``VIDIOCGCAPTURE`` and ``VIDIOCSCAPTURE`` ioctls using struct
+:c:type:`struct video_capture`. The equivalent V4L2 ioctls are
+:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and
+:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` using struct
+:ref:`v4l2_crop <v4l2-crop>`, and the related
+:ref:`VIDIOC_CROPCAP` ioctl. This is a rather
+complex matter, see :ref:`crop` for details.
+
+The ``x``, ``y``, ``width`` and ``height`` fields moved into struct
+:ref:`v4l2_rect <v4l2-rect>` substructure ``c`` of struct
+:c:type:`struct v4l2_crop`. The ``decimation`` field was dropped. In
+the V4L2 API the scaling factor is implied by the size of the cropping
+rectangle and the size of the captured or overlaid image.
+
+The ``VIDEO_CAPTURE_ODD`` and ``VIDEO_CAPTURE_EVEN`` flags to capture
+only the odd or even field, respectively, were replaced by
+``V4L2_FIELD_TOP`` and ``V4L2_FIELD_BOTTOM`` in the field named
+``field`` of struct :ref:`v4l2_pix_format <v4l2-pix-format>` and
+struct :ref:`v4l2_window <v4l2-window>`. These structures are used to
+select a capture or overlay format with the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+
+Reading Images, Memory Mapping
+==============================
+
+
+Capturing using the read method
+-------------------------------
+
+There is no essential difference between reading images from a V4L or
+V4L2 device using the :ref:`read() <func-read>` function, however V4L2
+drivers are not required to support this I/O method. Applications can
+determine if the function is available with the
+:ref:`VIDIOC_QUERYCAP` ioctl. All V4L2 devices
+exchanging data with applications must support the
+:ref:`select() <func-select>` and :ref:`poll() <func-poll>`
+functions.
+
+To select an image format and size, V4L provides the ``VIDIOCSPICT`` and
+``VIDIOCSWIN`` ioctls. V4L2 uses the general-purpose data format
+negotiation ioctls :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`. They take a pointer to a struct
+:ref:`v4l2_format <v4l2-format>` as argument, here the struct
+:ref:`v4l2_pix_format <v4l2-pix-format>` named ``pix`` of its
+``fmt`` union is used.
+
+For more information about the V4L2 read interface see :ref:`rw`.
+
+
+Capturing using memory mapping
+------------------------------
+
+Applications can read from V4L devices by mapping buffers in device
+memory, or more often just buffers allocated in DMA-able system memory,
+into their address space. This avoids the data copying overhead of the
+read method. V4L2 supports memory mapping as well, with a few
+differences.
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+
+    -  .. row 1
+
+       -  V4L
+
+       -  V4L2
+
+    -  .. row 2
+
+       -
+       -  The image format must be selected before buffers are allocated,
+	  with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. When no
+	  format is selected the driver may use the last, possibly by
+	  another application requested format.
+
+    -  .. row 3
+
+       -  Applications cannot change the number of buffers. The it is built
+	  into the driver, unless it has a module option to change the
+	  number when the driver module is loaded.
+
+       -  The :ref:`VIDIOC_REQBUFS` ioctl allocates the
+	  desired number of buffers, this is a required step in the
+	  initialization sequence.
+
+    -  .. row 4
+
+       -  Drivers map all buffers as one contiguous range of memory. The
+	  ``VIDIOCGMBUF`` ioctl is available to query the number of buffers,
+	  the offset of each buffer from the start of the virtual file, and
+	  the overall amount of memory used, which can be used as arguments
+	  for the :ref:`mmap() <func-mmap>` function.
+
+       -  Buffers are individually mapped. The offset and size of each
+	  buffer can be determined with the
+	  :ref:`VIDIOC_QUERYBUF` ioctl.
+
+    -  .. row 5
+
+       -  The ``VIDIOCMCAPTURE`` ioctl prepares a buffer for capturing. It
+	  also determines the image format for this buffer. The ioctl
+	  returns immediately, eventually with an ``EAGAIN`` error code if no
+	  video signal had been detected. When the driver supports more than
+	  one buffer applications can call the ioctl multiple times and thus
+	  have multiple outstanding capture requests.
+
+	  The ``VIDIOCSYNC`` ioctl suspends execution until a particular
+	  buffer has been filled.
+
+       -  Drivers maintain an incoming and outgoing queue.
+	  :ref:`VIDIOC_QBUF` enqueues any empty buffer into
+	  the incoming queue. Filled buffers are dequeued from the outgoing
+	  queue with the :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. To wait
+	  until filled buffers become available this function,
+	  :ref:`select() <func-select>` or :ref:`poll() <func-poll>` can
+	  be used. The :ref:`VIDIOC_STREAMON` ioctl
+	  must be called once after enqueuing one or more buffers to start
+	  capturing. Its counterpart
+	  :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` stops capturing and
+	  dequeues all buffers from both queues. Applications can query the
+	  signal status, if known, with the
+	  :ref:`VIDIOC_ENUMINPUT` ioctl.
+
+
+For a more in-depth discussion of memory mapping and examples, see
+:ref:`mmap`.
+
+
+Reading Raw VBI Data
+====================
+
+Originally the V4L API did not specify a raw VBI capture interface, only
+the device file ``/dev/vbi`` was reserved for this purpose. The only
+driver supporting this interface was the BTTV driver, de-facto defining
+the V4L VBI interface. Reading from the device yields a raw VBI image
+with the following parameters:
+
+
+
+.. flat-table::
+    :header-rows:  1
+    :stub-columns: 0
+
+
+    -  .. row 1
+
+       -  struct :ref:`v4l2_vbi_format <v4l2-vbi-format>`
+
+       -  V4L, BTTV driver
+
+    -  .. row 2
+
+       -  sampling_rate
+
+       -  28636363 Hz NTSC (or any other 525-line standard); 35468950 Hz PAL
+	  and SECAM (625-line standards)
+
+    -  .. row 3
+
+       -  offset
+
+       -  ?
+
+    -  .. row 4
+
+       -  samples_per_line
+
+       -  2048
+
+    -  .. row 5
+
+       -  sample_format
+
+       -  V4L2_PIX_FMT_GREY. The last four bytes (a machine endianness
+	  integer) contain a frame counter.
+
+    -  .. row 6
+
+       -  start[]
+
+       -  10, 273 NTSC; 22, 335 PAL and SECAM
+
+    -  .. row 7
+
+       -  count[]
+
+       -  16, 16 [#f9]_
+
+    -  .. row 8
+
+       -  flags
+
+       -  0
+
+
+Undocumented in the V4L specification, in Linux 2.3 the
+``VIDIOCGVBIFMT`` and ``VIDIOCSVBIFMT`` ioctls using struct
+:c:type:`struct vbi_format` were added to determine the VBI image
+parameters. These ioctls are only partially compatible with the V4L2 VBI
+interface specified in :ref:`raw-vbi`.
+
+An ``offset`` field does not exist, ``sample_format`` is supposed to be
+``VIDEO_PALETTE_RAW``, equivalent to ``V4L2_PIX_FMT_GREY``. The
+remaining fields are probably equivalent to struct
+:ref:`v4l2_vbi_format <v4l2-vbi-format>`.
+
+Apparently only the Zoran (ZR 36120) driver implements these ioctls. The
+semantics differ from those specified for V4L2 in two ways. The
+parameters are reset on :ref:`open() <func-open>` and
+``VIDIOCSVBIFMT`` always returns an ``EINVAL`` error code if the parameters
+are invalid.
+
+
+Miscellaneous
+=============
+
+V4L2 has no equivalent of the ``VIDIOCGUNIT`` ioctl. Applications can
+find the VBI device associated with a video capture device (or vice
+versa) by reopening the device and requesting VBI data. For details see
+:ref:`open`.
+
+No replacement exists for ``VIDIOCKEY``, and the V4L functions for
+microcode programming. A new interface for MPEG compression and playback
+devices is documented in :ref:`extended-controls`.
+
+.. [#f1]
+   According to Documentation/devices.txt these should be symbolic links
+   to ``/dev/video0``. Note the original bttv interface is not
+   compatible with V4L or V4L2.
+
+.. [#f2]
+   According to ``Documentation/devices.txt`` a symbolic link to
+   ``/dev/radio0``.
+
+.. [#f3]
+   This is a custom format used by the BTTV driver, not one of the V4L2
+   standard formats.
+
+.. [#f4]
+   Presumably all V4L RGB formats are little-endian, although some
+   drivers might interpret them according to machine endianness. V4L2
+   defines little-endian, big-endian and red/blue swapped variants. For
+   details see :ref:`pixfmt-rgb`.
+
+.. [#f5]
+   ``VIDEO_PALETTE_YUV422`` and ``VIDEO_PALETTE_YUYV`` are the same
+   formats. Some V4L drivers respond to one, some to the other.
+
+.. [#f6]
+   Not to be confused with ``V4L2_PIX_FMT_YUV411P``, which is a planar
+   format.
+
+.. [#f7]
+   V4L explains this as: "RAW capture (BT848)"
+
+.. [#f8]
+   Not to be confused with ``V4L2_PIX_FMT_Y41P``, which is a packed
+   format.
+
+.. [#f9]
+   Old driver versions used different values, eventually the custom
+   ``BTTV_VBISIZE`` ioctl was added to query the correct values.

+************************************
+Streaming I/O (DMA buffer importing)
+************************************
+
+The DMABUF framework provides a generic method for sharing buffers
+between multiple devices. Device drivers that support DMABUF can export
+a DMA buffer to userspace as a file descriptor (known as the exporter
+role), import a DMA buffer from userspace using a file descriptor
+previously exported for a different or the same device (known as the
+importer role), or both. This section describes the DMABUF importer role
+API in V4L2.
+
+Refer to :ref:`DMABUF exporting <VIDIOC_EXPBUF>` for details about
+exporting V4L2 buffers as DMABUF file descriptors.
+
+Input and output devices support the streaming I/O method when the
+``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP <VIDIOC_QUERYCAP>` ioctl is set. Whether
+importing DMA buffers through DMABUF file descriptors is supported is
+determined by calling the :ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`
+ioctl with the memory type set to ``V4L2_MEMORY_DMABUF``.
+
+This I/O method is dedicated to sharing DMA buffers between different
+devices, which may be V4L devices or other video-related devices (e.g.
+DRM). Buffers (planes) are allocated by a driver on behalf of an
+application. Next, these buffers are exported to the application as file
+descriptors using an API which is specific for an allocator driver. Only
+such file descriptor are exchanged. The descriptors and meta-information
+are passed in struct :ref:`v4l2_buffer <v4l2-buffer>` (or in struct
+:ref:`v4l2_plane <v4l2-plane>` in the multi-planar API case). The
+driver must be switched into DMABUF I/O mode by calling the
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>` with the desired buffer type.
+
+
+Example: Initiating streaming I/O with DMABUF file descriptors
+==============================================================
+
+.. code-block:: c
+
+    struct v4l2_requestbuffers reqbuf;
+
+    memset(&reqbuf, 0, sizeof (reqbuf));
+    reqbuf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
+    reqbuf.memory = V4L2_MEMORY_DMABUF;
+    reqbuf.count = 1;
+
+    if (ioctl(fd, VIDIOC_REQBUFS, &reqbuf) == -1) {
+	if (errno == EINVAL)
+	    printf("Video capturing or DMABUF streaming is not supported\\n");
+	else
+	    perror("VIDIOC_REQBUFS");
+
+	exit(EXIT_FAILURE);
+    }
+
+The buffer (plane) file descriptor is passed on the fly with the
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl. In case of multiplanar
+buffers, every plane can be associated with a different DMABUF
+descriptor. Although buffers are commonly cycled, applications can pass
+a different DMABUF descriptor at each :ref:`VIDIOC_QBUF <VIDIOC_QBUF>` call.
+
+Example: Queueing DMABUF using single plane API
+===============================================
+
+.. code-block:: c
+
+    int buffer_queue(int v4lfd, int index, int dmafd)
+    {
+	struct v4l2_buffer buf;
+
+	memset(&buf, 0, sizeof buf);
+	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
+	buf.memory = V4L2_MEMORY_DMABUF;
+	buf.index = index;
+	buf.m.fd = dmafd;
+
+	if (ioctl(v4lfd, VIDIOC_QBUF, &buf) == -1) {
+	    perror("VIDIOC_QBUF");
+	    return -1;
+	}
+
+	return 0;
+    }
+
+Example 3.6. Queueing DMABUF using multi plane API
+==================================================
+
+.. code-block:: c
+
+    int buffer_queue_mp(int v4lfd, int index, int dmafd[], int n_planes)
+    {
+	struct v4l2_buffer buf;
+	struct v4l2_plane planes[VIDEO_MAX_PLANES];
+	int i;
+
+	memset(&buf, 0, sizeof buf);
+	buf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE;
+	buf.memory = V4L2_MEMORY_DMABUF;
+	buf.index = index;
+	buf.m.planes = planes;
+	buf.length = n_planes;
+
+	memset(&planes, 0, sizeof planes);
+
+	for (i = 0; i < n_planes; ++i)
+	    buf.m.planes[i].m.fd = dmafd[i];
+
+	if (ioctl(v4lfd, VIDIOC_QBUF, &buf) == -1) {
+	    perror("VIDIOC_QBUF");
+	    return -1;
+	}
+
+	return 0;
+    }
+
+Captured or displayed buffers are dequeued with the
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. The driver can unlock the
+buffer at any time between the completion of the DMA and this ioctl. The
+memory is also unlocked when
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called,
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, or when the device is closed.
+
+For capturing applications it is customary to enqueue a number of empty
+buffers, to start capturing and enter the read loop. Here the
+application waits until a filled buffer can be dequeued, and re-enqueues
+the buffer when the data is no longer needed. Output applications fill
+and enqueue buffers, when enough buffers are stacked up output is
+started. In the write loop, when the application runs out of free
+buffers it must wait until an empty buffer can be dequeued and reused.
+Two methods exist to suspend execution of the application until one or
+more buffers can be dequeued. By default :ref:`VIDIOC_DQBUF
+<VIDIOC_QBUF>` blocks when no buffer is in the outgoing queue. When the
+``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>` function,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
+error code when no buffer is available. The
+:ref:`select() <func-select>` and :ref:`poll() <func-poll>`
+functions are always available.
+
+To start and stop capturing or displaying applications call the
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls.
+
+.. note::
+
+   :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` removes all buffers from
+   both queues and unlocks all buffers as a side effect. Since there is no
+   notion of doing anything "now" on a multitasking system, if an
+   application needs to synchronize with another event it should examine
+   the struct :ref:`v4l2_buffer <v4l2-buffer>` ``timestamp`` of captured or
+   outputted buffers.
+
+Drivers implementing DMABUF importing I/O must support the
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON
+<VIDIOC_STREAMON>` and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls,
+and the :ref:`select() <func-select>` and :ref:`poll() <func-poll>`
+functions.

+Digital Video (DV) Timings
+**************************
+
+The video standards discussed so far have been dealing with Analog TV
+and the corresponding video timings. Today there are many more different
+hardware interfaces such as High Definition TV interfaces (HDMI), VGA,
+DVI connectors etc., that carry video signals and there is a need to
+extend the API to select the video timings for these interfaces. Since
+it is not possible to extend the :ref:`v4l2_std_id <v4l2-std-id>`
+due to the limited bits available, a new set of ioctls was added to
+set/get video timings at the input and output.
+
+These ioctls deal with the detailed digital video timings that define
+each video format. This includes parameters such as the active video
+width and height, signal polarities, frontporches, backporches, sync
+widths etc. The ``linux/v4l2-dv-timings.h`` header can be used to get
+the timings of the formats in the :ref:`cea861` and :ref:`vesadmt`
+standards.
+
+To enumerate and query the attributes of the DV timings supported by a
+device applications use the
+:ref:`VIDIOC_ENUM_DV_TIMINGS` and
+:ref:`VIDIOC_DV_TIMINGS_CAP` ioctls. To set
+DV timings for the device applications use the
+:ref:`VIDIOC_S_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl and to get
+current DV timings they use the
+:ref:`VIDIOC_G_DV_TIMINGS <VIDIOC_G_DV_TIMINGS>` ioctl. To detect
+the DV timings as seen by the video receiver applications use the
+:ref:`VIDIOC_QUERY_DV_TIMINGS` ioctl.
+
+Applications can make use of the :ref:`input-capabilities` and
+:ref:`output-capabilities` flags to determine whether the digital
+video ioctls can be used with the given input or output.

+Introduction
+============
+
+The control mechanism as originally designed was meant to be used for
+user settings (brightness, saturation, etc). However, it turned out to
+be a very useful model for implementing more complicated driver APIs
+where each driver implements only a subset of a larger API.
+
+The MPEG encoding API was the driving force behind designing and
+implementing this extended control mechanism: the MPEG standard is quite
+large and the currently supported hardware MPEG encoders each only
+implement a subset of this standard. Further more, many parameters
+relating to how the video is encoded into an MPEG stream are specific to
+the MPEG encoding chip since the MPEG standard only defines the format
+of the resulting MPEG stream, not how the video is actually encoded into
+that format.
+
+Unfortunately, the original control API lacked some features needed for
+these new uses and so it was extended into the (not terribly originally
+named) extended control API.
+
+Even though the MPEG encoding API was the first effort to use the
+Extended Control API, nowadays there are also other classes of Extended
+Controls, such as Camera Controls and FM Transmitter Controls. The
+Extended Controls API as well as all Extended Controls classes are
+described in the following text.
+
+
+The Extended Control API
+========================
+
+Three new ioctls are available:
+:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
+:ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
+:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`. These ioctls act
+on arrays of controls (as opposed to the
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls that act on a single
+control). This is needed since it is often required to atomically change
+several controls at once.
+
+Each of the new ioctls expects a pointer to a struct
+:ref:`v4l2_ext_controls <v4l2-ext-controls>`. This structure
+contains a pointer to the control array, a count of the number of
+controls in that array and a control class. Control classes are used to
+group similar controls into a single class. For example, control class
+``V4L2_CTRL_CLASS_USER`` contains all user controls (i. e. all controls
+that can also be set using the old :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>`
+ioctl). Control class ``V4L2_CTRL_CLASS_MPEG`` contains all controls
+relating to MPEG encoding, etc.
+
+All controls in the control array must belong to the specified control
+class. An error is returned if this is not the case.
+
+It is also possible to use an empty control array (``count`` == 0) to check
+whether the specified control class is supported.
+
+The control array is a struct
+:ref:`v4l2_ext_control <v4l2-ext-control>` array. The
+:ref:`struct v4l2_ext_control <v4l2-ext-control>` structure is very similar to
+struct :ref:`v4l2_control <v4l2-control>`, except for the fact that
+it also allows for 64-bit values and pointers to be passed.
+
+Since the struct :ref:`v4l2_ext_control <v4l2-ext-control>` supports
+pointers it is now also possible to have controls with compound types
+such as N-dimensional arrays and/or structures. You need to specify the
+``V4L2_CTRL_FLAG_NEXT_COMPOUND`` when enumerating controls to actually
+be able to see such compound controls. In other words, these controls
+with compound types should only be used programmatically.
+
+Since such compound controls need to expose more information about
+themselves than is possible with
+:ref:`VIDIOC_QUERYCTRL` the
+:ref:`VIDIOC_QUERY_EXT_CTRL <VIDIOC_QUERYCTRL>` ioctl was added. In
+particular, this ioctl gives the dimensions of the N-dimensional array
+if this control consists of more than one element.
+
+.. note::
+
+   #. It is important to realize that due to the flexibility of controls it is
+      necessary to check whether the control you want to set actually is
+      supported in the driver and what the valid range of values is. So use
+      the :ref:`VIDIOC_QUERYCTRL` (or :ref:`VIDIOC_QUERY_EXT_CTRL
+      <VIDIOC_QUERYCTRL>`) and :ref:`VIDIOC_QUERYMENU <VIDIOC_QUERYCTRL>`
+      ioctls to check this.
+
+   #. It is possible that some of the menu indices in a control of
+      type ``V4L2_CTRL_TYPE_MENU`` may not be supported (``VIDIOC_QUERYMENU``
+      will return an error). A good example is the list of supported MPEG
+      audio bitrates. Some drivers only support one or two bitrates, others
+      support a wider range.
+
+All controls use machine endianness.
+
+
+Enumerating Extended Controls
+=============================
+
+The recommended way to enumerate over the extended controls is by using
+:ref:`VIDIOC_QUERYCTRL` in combination with the
+``V4L2_CTRL_FLAG_NEXT_CTRL`` flag:
+
+
+.. code-block:: c
+
+    struct v4l2_queryctrl qctrl;
+
+    qctrl.id = V4L2_CTRL_FLAG_NEXT_CTRL;
+    while (0 == ioctl (fd, VIDIOC_QUERYCTRL, &qctrl)) {
+	/* ... */
+	qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
+    }
+
+The initial control ID is set to 0 ORed with the
+``V4L2_CTRL_FLAG_NEXT_CTRL`` flag. The ``VIDIOC_QUERYCTRL`` ioctl will
+return the first control with a higher ID than the specified one. When
+no such controls are found an error is returned.
+
+If you want to get all controls within a specific control class, then
+you can set the initial ``qctrl.id`` value to the control class and add
+an extra check to break out of the loop when a control of another
+control class is found:
+
+
+.. code-block:: c
+
+    qctrl.id = V4L2_CTRL_CLASS_MPEG | V4L2_CTRL_FLAG_NEXT_CTRL;
+    while (0 == ioctl(fd, VIDIOC_QUERYCTRL, &qctrl)) {
+	if (V4L2_CTRL_ID2CLASS(qctrl.id) != V4L2_CTRL_CLASS_MPEG)
+	    break;
+	    /* ... */
+	qctrl.id |= V4L2_CTRL_FLAG_NEXT_CTRL;
+    }
+
+The 32-bit ``qctrl.id`` value is subdivided into three bit ranges: the
+top 4 bits are reserved for flags (e. g. ``V4L2_CTRL_FLAG_NEXT_CTRL``)
+and are not actually part of the ID. The remaining 28 bits form the
+control ID, of which the most significant 12 bits define the control
+class and the least significant 16 bits identify the control within the
+control class. It is guaranteed that these last 16 bits are always
+non-zero for controls. The range of 0x1000 and up are reserved for
+driver-specific controls. The macro ``V4L2_CTRL_ID2CLASS(id)`` returns
+the control class ID based on a control ID.
+
+If the driver does not support extended controls, then
+``VIDIOC_QUERYCTRL`` will fail when used in combination with
+``V4L2_CTRL_FLAG_NEXT_CTRL``. In that case the old method of enumerating
+control should be used (see :ref:`enum_all_controls`). But if it is
+supported, then it is guaranteed to enumerate over all controls,
+including driver-private controls.
+
+
+Creating Control Panels
+=======================
+
+It is possible to create control panels for a graphical user interface
+where the user can select the various controls. Basically you will have
+to iterate over all controls using the method described above. Each
+control class starts with a control of type
+``V4L2_CTRL_TYPE_CTRL_CLASS``. ``VIDIOC_QUERYCTRL`` will return the name
+of this control class which can be used as the title of a tab page
+within a control panel.
+
+The flags field of struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` also
+contains hints on the behavior of the control. See the
+:ref:`VIDIOC_QUERYCTRL` documentation for more
+details.
+
+
+.. _mpeg-controls:
+
+Codec Control Reference
+=======================
+
+Below all controls within the Codec control class are described. First
+the generic controls, then controls specific for certain hardware.
+
+.. note:: These controls are applicable to all codecs and not just MPEG. The
+   defines are prefixed with V4L2_CID_MPEG/V4L2_MPEG as the controls
+   were originally made for MPEG codecs and later extended to cover all
+   encoding formats.

+
+.. _v4l2-exposure-auto-type:
+
+``V4L2_CID_EXPOSURE_AUTO (enum v4l2_exposure_auto_type)``
+    Enables automatic adjustments of the exposure time and/or iris
+    aperture. The effect of manual changes of the exposure time or iris
+    aperture while these features are enabled is undefined, drivers
+    should ignore such requests. Possible values are:
+

+
+
+    -  .. row 1

+
+       -  Auto exposure time, manual iris.
+
+
+
+``V4L2_CID_EXPOSURE_ABSOLUTE (integer)``
+    Determines the exposure time of the camera sensor. The exposure time
+    is limited by the frame interval. Drivers should interpret the
+    values as 100 µs units, where the value 1 stands for 1/10000th of a
+    second, 10000 for 1 second and 100000 for 10 seconds.
+
+``V4L2_CID_EXPOSURE_AUTO_PRIORITY (boolean)``
+    When ``V4L2_CID_EXPOSURE_AUTO`` is set to ``AUTO`` or
+    ``APERTURE_PRIORITY``, this control determines if the device may
+    dynamically vary the frame rate. By default this feature is disabled
+    (0) and the frame rate must remain constant.
+
+``V4L2_CID_EXPOSURE_BIAS (integer menu)``
+    Determines the automatic exposure compensation, it is effective only
+    when ``V4L2_CID_EXPOSURE_AUTO`` control is set to ``AUTO``,
+    ``SHUTTER_PRIORITY`` or ``APERTURE_PRIORITY``. It is expressed in
+    terms of EV, drivers should interpret the values as 0.001 EV units,
+    where the value 1000 stands for +1 EV.
+
+    Increasing the exposure compensation value is equivalent to
+    decreasing the exposure value (EV) and will increase the amount of
+    light at the image sensor. The camera performs the exposure
+    compensation by adjusting absolute exposure time and/or aperture.
+
+.. _v4l2-exposure-metering:
+
+``V4L2_CID_EXPOSURE_METERING (enum v4l2_exposure_metering)``

+    further, negative values close it one step further. This is a
+    write-only control.
+
+``V4L2_CID_PRIVACY (boolean)``
+    Prevent video from being acquired by the camera. When this control
+    is set to ``TRUE`` (1), no image can be captured by the camera.
+    Common means to enforce privacy are mechanical obturation of the
+    sensor and firmware image processing, but the device is not
+    restricted to these methods. Devices that implement the privacy
+    control must support read access and may support write access.
+
+``V4L2_CID_BAND_STOP_FILTER (integer)``
+    Switch the band-stop filter of a camera sensor on or off, or specify

+    camera determines best exposure, aperture, focusing, light metering,
+    white balance and equivalent sensitivity. The controls of those
+    parameters are influenced by the scene mode control. An exact
+    behavior in each mode is subject to the camera specification.
+
+    When the scene mode feature is not used, this control should be set
+    to ``V4L2_SCENE_MODE_NONE`` to make sure the other possibly related

+
+    -  .. row 3
+
+       -  ``V4L2_SCENE_MODE_BEACH_SNOW``
+
+       -  Beach and snow. This mode compensates for all-white or bright
+	  scenes, which tend to look gray and low contrast, when camera's
+	  automatic exposure is based on an average scene brightness. To
+	  compensate, this mode automatically slightly overexposes the
+	  frames. The white balance may also be adjusted to compensate for
+	  the fact that reflected snow looks bluish rather than white.
+
+    -  .. row 4
+
+       -  ``V4L2_SCENE_MODE_CANDLELIGHT``
+
+       -  Candle light. The camera generally raises the ISO sensitivity and

+
+    -  .. row 5
+
+       -  ``V4L2_SCENE_MODE_DAWN_DUSK``
+
+       -  Dawn and dusk. Preserves the colors seen in low natural light

+
+    -  .. row 8
+
+       -  ``V4L2_SCENE_MODE_LANDSCAPE``
+
+       -  Landscape. The camera may choose a small aperture to provide deep

+	  in dim light conditions. The focus is fixed at infinity. Suitable
+	  for distant and wide scenery.
+
+    -  .. row 9
+
+       -  ``V4L2_SCENE_MODE_NIGHT``
+
+       -  Night, also known as Night Landscape. Designed for low light
+	  conditions, it preserves detail in the dark areas without blowing
+	  out bright objects. The camera generally sets itself to a
+	  medium-to-high ISO sensitivity, with a relatively long exposure
+	  time, and turns flash off. As such, there will be increased image
+	  noise and the possibility of blurred image.
+
+    -  .. row 10
+

+
+    -  .. row 11
+
+       -  ``V4L2_SCENE_MODE_PORTRAIT``
+
+       -  Portrait. The camera adjusts the aperture so that the depth of
+	  field is reduced, which helps to isolate the subject against a
+	  smooth background. Most cameras recognize the presence of faces in
+	  the scene and focus on them. The color hue is adjusted to enhance
+	  skin tones. The intensity of the flash is often reduced.
+
+    -  .. row 12
+
+       -  ``V4L2_SCENE_MODE_SPORTS``

+FM Transmitter Control Reference
+================================
+
+The FM Transmitter (FM_TX) class includes controls for common features
+of FM transmissions capable devices. Currently this class includes
+parameters for audio compression, pilot tone generation, audio deviation
+limiter, RDS transmission and tuning power features.
+
+
+.. _fm-tx-control-id:
+
+FM_TX Control IDs
+-----------------
+
+``V4L2_CID_FM_TX_CLASS (class)``
+    The FM_TX class descriptor. Calling
+    :ref:`VIDIOC_QUERYCTRL` for this control will
+    return a description of this control class.
+
+``V4L2_CID_RDS_TX_DEVIATION (integer)``
+    Configures RDS signal frequency deviation level in Hz. The range and
+    step are driver-specific.
+
+``V4L2_CID_RDS_TX_PI (integer)``
+    Sets the RDS Programme Identification field for transmission.
+
+``V4L2_CID_RDS_TX_PTY (integer)``
+    Sets the RDS Programme Type field for transmission. This encodes up
+    to 31 pre-defined programme types.
+
+``V4L2_CID_RDS_TX_PS_NAME (string)``
+    Sets the Programme Service name (PS_NAME) for transmission. It is
+    intended for static display on a receiver. It is the primary aid to
+    listeners in programme service identification and selection. In
+    Annex E of :ref:`iec62106`, the RDS specification, there is a full
+    description of the correct character encoding for Programme Service
+    name strings. Also from RDS specification, PS is usually a single
+    eight character text. However, it is also possible to find receivers
+    which can scroll strings sized as 8 x N characters. So, this control
+    must be configured with steps of 8 characters. The result is it must
+    always contain a string with size multiple of 8.
+
+``V4L2_CID_RDS_TX_RADIO_TEXT (string)``
+    Sets the Radio Text info for transmission. It is a textual
+    description of what is being broadcasted. RDS Radio Text can be
+    applied when broadcaster wishes to transmit longer PS names,
+    programme-related information or any other text. In these cases,
+    RadioText should be used in addition to ``V4L2_CID_RDS_TX_PS_NAME``.
+    The encoding for Radio Text strings is also fully described in Annex
+    E of :ref:`iec62106`. The length of Radio Text strings depends on
+    which RDS Block is being used to transmit it, either 32 (2A block)
+    or 64 (2B block). However, it is also possible to find receivers
+    which can scroll strings sized as 32 x N or 64 x N characters. So,
+    this control must be configured with steps of 32 or 64 characters.
+    The result is it must always contain a string with size multiple of
+    32 or 64.
+
+``V4L2_CID_RDS_TX_MONO_STEREO (boolean)``
+    Sets the Mono/Stereo bit of the Decoder Identification code. If set,
+    then the audio was recorded as stereo.
+
+``V4L2_CID_RDS_TX_ARTIFICIAL_HEAD (boolean)``
+    Sets the
+    `Artificial Head <http://en.wikipedia.org/wiki/Artificial_head>`__
+    bit of the Decoder Identification code. If set, then the audio was
+    recorded using an artificial head.
+
+``V4L2_CID_RDS_TX_COMPRESSED (boolean)``
+    Sets the Compressed bit of the Decoder Identification code. If set,
+    then the audio is compressed.
+
+``V4L2_CID_RDS_TX_DYNAMIC_PTY (boolean)``
+    Sets the Dynamic PTY bit of the Decoder Identification code. If set,
+    then the PTY code is dynamically switched.
+
+``V4L2_CID_RDS_TX_TRAFFIC_ANNOUNCEMENT (boolean)``
+    If set, then a traffic announcement is in progress.
+
+``V4L2_CID_RDS_TX_TRAFFIC_PROGRAM (boolean)``
+    If set, then the tuned programme carries traffic announcements.
+
+``V4L2_CID_RDS_TX_MUSIC_SPEECH (boolean)``
+    If set, then this channel broadcasts music. If cleared, then it
+    broadcasts speech. If the transmitter doesn't make this distinction,
+    then it should be set.
+
+``V4L2_CID_RDS_TX_ALT_FREQS_ENABLE (boolean)``
+    If set, then transmit alternate frequencies.
+
+``V4L2_CID_RDS_TX_ALT_FREQS (__u32 array)``
+    The alternate frequencies in kHz units. The RDS standard allows for
+    up to 25 frequencies to be defined. Drivers may support fewer
+    frequencies so check the array size.
+
+``V4L2_CID_AUDIO_LIMITER_ENABLED (boolean)``
+    Enables or disables the audio deviation limiter feature. The limiter
+    is useful when trying to maximize the audio volume, minimize
+    receiver-generated distortion and prevent overmodulation.
+
+``V4L2_CID_AUDIO_LIMITER_RELEASE_TIME (integer)``
+    Sets the audio deviation limiter feature release time. Unit is in
+    useconds. Step and range are driver-specific.
+
+``V4L2_CID_AUDIO_LIMITER_DEVIATION (integer)``
+    Configures audio frequency deviation level in Hz. The range and step
+    are driver-specific.
+
+``V4L2_CID_AUDIO_COMPRESSION_ENABLED (boolean)``
+    Enables or disables the audio compression feature. This feature
+    amplifies signals below the threshold by a fixed gain and compresses
+    audio signals above the threshold by the ratio of Threshold/(Gain +
+    Threshold).
+
+``V4L2_CID_AUDIO_COMPRESSION_GAIN (integer)``
+    Sets the gain for audio compression feature. It is a dB value. The
+    range and step are driver-specific.
+
+``V4L2_CID_AUDIO_COMPRESSION_THRESHOLD (integer)``
+    Sets the threshold level for audio compression freature. It is a dB
+    value. The range and step are driver-specific.
+
+``V4L2_CID_AUDIO_COMPRESSION_ATTACK_TIME (integer)``
+    Sets the attack time for audio compression feature. It is a useconds
+    value. The range and step are driver-specific.
+
+``V4L2_CID_AUDIO_COMPRESSION_RELEASE_TIME (integer)``
+    Sets the release time for audio compression feature. It is a
+    useconds value. The range and step are driver-specific.
+
+``V4L2_CID_PILOT_TONE_ENABLED (boolean)``
+    Enables or disables the pilot tone generation feature.
+
+``V4L2_CID_PILOT_TONE_DEVIATION (integer)``
+    Configures pilot tone frequency deviation level. Unit is in Hz. The
+    range and step are driver-specific.
+
+``V4L2_CID_PILOT_TONE_FREQUENCY (integer)``
+    Configures pilot tone frequency value. Unit is in Hz. The range and
+    step are driver-specific.
+
+``V4L2_CID_TUNE_PREEMPHASIS (enum v4l2_preemphasis)``
+    Configures the pre-emphasis value for broadcasting. A pre-emphasis
+    filter is applied to the broadcast to accentuate the high audio
+    frequencies. Depending on the region, a time constant of either 50
+    or 75 useconds is used. The enum v4l2_preemphasis defines possible
+    values for pre-emphasis. Here they are:

+Flash Control Reference
+=======================
+
+The V4L2 flash controls are intended to provide generic access to flash
+controller devices. Flash controller devices are typically used in
+digital cameras.
+
+The interface can support both LED and xenon flash devices. As of
+writing this, there is no xenon flash driver using this interface.
+
+
+.. _flash-controls-use-cases:
+
+Supported use cases
+-------------------
+
+
+Unsynchronised LED flash (software strobe)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+Unsynchronised LED flash is controlled directly by the host as the
+sensor. The flash must be enabled by the host before the exposure of the
+image starts and disabled once it ends. The host is fully responsible
+for the timing of the flash.
+
+Example of such device: Nokia N900.
+
+
+Synchronised LED flash (hardware strobe)
+^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+
+The synchronised LED flash is pre-programmed by the host (power and
+timeout) but controlled by the sensor through a strobe signal from the
+sensor to the flash.
+
+The sensor controls the flash duration and timing. This information
+typically must be made available to the sensor.
+
+
+LED flash as torch
+^^^^^^^^^^^^^^^^^^
+
+LED flash may be used as torch in conjunction with another use case
+involving camera or individually.

+    The IMAGE_SOURCE class descriptor.
+
+``V4L2_CID_VBLANK (integer)``
+    Vertical blanking. The idle period after every frame during which no
+    image data is produced. The unit of vertical blanking is a line.
+    Every line has length of the image width plus horizontal blanking at
+    the pixel rate defined by ``V4L2_CID_PIXEL_RATE`` control in the
+    same sub-device.
+
+``V4L2_CID_HBLANK (integer)``
+    Horizontal blanking. The idle period after every line of image data

+    blanking is pixels.
+
+``V4L2_CID_ANALOGUE_GAIN (integer)``
+    Analogue gain is gain affecting all colour components in the pixel
+    matrix. The gain operation is performed in the analogue domain
+    before A/D conversion.

+
+.. _image-process-controls:
+
+Image Process Control Reference
+===============================
+
+The Image Process control class is intended for low-level control of
+image processing functions. Unlike ``V4L2_CID_IMAGE_SOURCE_CLASS``, the
+controls in this class affect processing the image, and do not control
+capturing of it.
+
+
+.. _image-process-control-id:
+
+Image Process Control IDs
+-------------------------
+
+``V4L2_CID_IMAGE_PROC_CLASS (class)``
+    The IMAGE_PROC class descriptor.
+
+``V4L2_CID_LINK_FREQ (integer menu)``
+    Data bus frequency. Together with the media bus pixel code, bus type
+    (clock cycles per sample), the data bus frequency defines the pixel
+    rate (``V4L2_CID_PIXEL_RATE``) in the pixel array (or possibly
+    elsewhere, if the device is not an image sensor). The frame rate can
+    be calculated from the pixel clock, image width and height and
+    horizontal and vertical blanking. While the pixel rate control may
+    be defined elsewhere than in the subdev containing the pixel array,
+    the frame rate cannot be obtained from that information. This is
+    because only on the pixel array it can be assumed that the vertical
+    and horizontal blanking information is exact: no other blanking is
+    allowed in the pixel array. The selection of frame rate is performed
+    by selecting the desired horizontal and vertical blanking. The unit
+    of this control is Hz.
+
+``V4L2_CID_PIXEL_RATE (64-bit integer)``
+    Pixel rate in the source pads of the subdev. This control is
+    read-only and its unit is pixels / second.
+
+``V4L2_CID_TEST_PATTERN (menu)``
+    Some capture/display/sensor devices have the capability to generate
+    test pattern images. These hardware specific test patterns can be
+    used to test if a device is working properly.
+
+
+.. _dv-controls:
+
+Digital Video Control Reference
+===============================
+
+The Digital Video control class is intended to control receivers and
+transmitters for `VGA <http://en.wikipedia.org/wiki/Vga>`__,
+`DVI <http://en.wikipedia.org/wiki/Digital_Visual_Interface>`__
+(Digital Visual Interface), HDMI (:ref:`hdmi`) and DisplayPort
+(:ref:`dp`). These controls are generally expected to be private to
+the receiver or transmitter subdevice that implements them, so they are
+only exposed on the ``/dev/v4l-subdev*`` device node.
+
+.. note::
+
+   Note that these devices can have multiple input or output pads which are
+   hooked up to e.g. HDMI connectors. Even though the subdevice will
+   receive or transmit video from/to only one of those pads, the other pads
+   can still be active when it comes to EDID (Extended Display
+   Identification Data, :ref:`vesaedid`) and HDCP (High-bandwidth Digital
+   Content Protection System, :ref:`hdcp`) processing, allowing the
+   device to do the fairly slow EDID/HDCP handling in advance. This allows
+   for quick switching between connectors.
+
+These pads appear in several of the controls in this section as
+bitmasks, one bit for each pad. Bit 0 corresponds to pad 0, bit 1 to pad
+1, etc. The maximum value of the control is the set of valid pads.
+
+
+.. _dv-control-id:
+
+Digital Video Control IDs
+-------------------------
+
+``V4L2_CID_DV_CLASS (class)``
+    The Digital Video class descriptor.
+
+``V4L2_CID_DV_TX_HOTPLUG (bitmask)``
+    Many connectors have a hotplug pin which is high if EDID information
+    is available from the source. This control shows the state of the
+    hotplug pin as seen by the transmitter. Each bit corresponds to an
+    output pad on the transmitter. If an output pad does not have an
+    associated hotplug pin, then the bit for that pad will be 0. This
+    read-only control is applicable to DVI-D, HDMI and DisplayPort
+    connectors.
+
+``V4L2_CID_DV_TX_RXSENSE (bitmask)``
+    Rx Sense is the detection of pull-ups on the TMDS clock lines. This
+    normally means that the sink has left/entered standby (i.e. the
+    transmitter can sense that the receiver is ready to receive video).
+    Each bit corresponds to an output pad on the transmitter. If an
+    output pad does not have an associated Rx Sense, then the bit for
+    that pad will be 0. This read-only control is applicable to DVI-D
+    and HDMI devices.
+
+``V4L2_CID_DV_TX_EDID_PRESENT (bitmask)``
+    When the transmitter sees the hotplug signal from the receiver it
+    will attempt to read the EDID. If set, then the transmitter has read
+    at least the first block (= 128 bytes). Each bit corresponds to an
+    output pad on the transmitter. If an output pad does not support
+    EDIDs, then the bit for that pad will be 0. This read-only control
+    is applicable to VGA, DVI-A/D, HDMI and DisplayPort connectors.
+
+``V4L2_CID_DV_TX_MODE (enum v4l2_dv_tx_mode)``
+    HDMI transmitters can transmit in DVI-D mode (just video) or in HDMI
+    mode (video + audio + auxiliary data). This control selects which
+    mode to use: V4L2_DV_TX_MODE_DVI_D or V4L2_DV_TX_MODE_HDMI.
+    This control is applicable to HDMI connectors.
+
+``V4L2_CID_DV_TX_RGB_RANGE (enum v4l2_dv_rgb_range)``
+    Select the quantization range for RGB output. V4L2_DV_RANGE_AUTO
+    follows the RGB quantization range specified in the standard for the
+    video interface (ie. :ref:`cea861` for HDMI).
+    V4L2_DV_RANGE_LIMITED and V4L2_DV_RANGE_FULL override the
+    standard to be compatible with sinks that have not implemented the
+    standard correctly (unfortunately quite common for HDMI and DVI-D).
+    Full range allows all possible values to be used whereas limited
+    range sets the range to (16 << (N-8)) - (235 << (N-8)) where N is
+    the number of bits per component. This control is applicable to VGA,
+    DVI-A/D, HDMI and DisplayPort connectors.
+
+``V4L2_CID_DV_TX_IT_CONTENT_TYPE (enum v4l2_dv_it_content_type)``
+    Configures the IT Content Type of the transmitted video. This
+    information is sent over HDMI and DisplayPort connectors as part of
+    the AVI InfoFrame. The term 'IT Content' is used for content that
+    originates from a computer as opposed to content from a TV broadcast
+    or an analog source. The enum v4l2_dv_it_content_type defines
+    the possible content types:
+
+
+
+.. flat-table::
+    :header-rows:  0
+    :stub-columns: 0

+
+       -  No IT Content information is available and the ITC bit in the AVI
+	  InfoFrame is set to 0.
+
+
+
+``V4L2_CID_DV_RX_POWER_PRESENT (bitmask)``
+    Detects whether the receiver receives power from the source (e.g.
+    HDMI carries 5V on one of the pins). This is often used to power an
+    eeprom which contains EDID information, such that the source can
+    read the EDID even if the sink is in standby/power off. Each bit
+    corresponds to an input pad on the transmitter. If an input pad
+    cannot detect whether power is present, then the bit for that pad
+    will be 0. This read-only control is applicable to DVI-D, HDMI and
+    DisplayPort connectors.
+
+``V4L2_CID_DV_RX_RGB_RANGE (enum v4l2_dv_rgb_range)``
+    Select the quantization range for RGB input. V4L2_DV_RANGE_AUTO
+    follows the RGB quantization range specified in the standard for the
+    video interface (ie. :ref:`cea861` for HDMI).
+    V4L2_DV_RANGE_LIMITED and V4L2_DV_RANGE_FULL override the
+    standard to be compatible with sources that have not implemented the
+    standard correctly (unfortunately quite common for HDMI and DVI-D).
+    Full range allows all possible values to be used whereas limited
+    range sets the range to (16 << (N-8)) - (235 << (N-8)) where N is

+    DVI-A/D, HDMI and DisplayPort connectors.
+
+``V4L2_CID_DV_RX_IT_CONTENT_TYPE (enum v4l2_dv_it_content_type)``
+    Reads the IT Content Type of the received video. This information is
+    sent over HDMI and DisplayPort connectors as part of the AVI
+    InfoFrame. The term 'IT Content' is used for content that originates
+    from a computer as opposed to content from a TV broadcast or an

+    return a description of this control class.
+
+``V4L2_CID_RDS_RECEPTION (boolean)``
+    Enables/disables RDS reception by the radio tuner
+
+``V4L2_CID_RDS_RX_PTY (integer)``
+    Gets RDS Programme Type field. This encodes up to 31 pre-defined
+    programme types.
+
+``V4L2_CID_RDS_RX_PS_NAME (string)``
+    Gets the Programme Service name (PS_NAME). It is intended for
+    static display on a receiver. It is the primary aid to listeners in
+    programme service identification and selection. In Annex E of
+    :ref:`iec62106`, the RDS specification, there is a full
+    description of the correct character encoding for Programme Service
+    name strings. Also from RDS specification, PS is usually a single
+    eight character text. However, it is also possible to find receivers
+    which can scroll strings sized as 8 x N characters. So, this control
+    must be configured with steps of 8 characters. The result is it must
+    always contain a string with size multiple of 8.
+
+``V4L2_CID_RDS_RX_RADIO_TEXT (string)``
+    Gets the Radio Text info. It is a textual description of what is
+    being broadcasted. RDS Radio Text can be applied when broadcaster
+    wishes to transmit longer PS names, programme-related information or
+    any other text. In these cases, RadioText can be used in addition to
+    ``V4L2_CID_RDS_RX_PS_NAME``. The encoding for Radio Text strings is
+    also fully described in Annex E of :ref:`iec62106`. The length of
+    Radio Text strings depends on which RDS Block is being used to
+    transmit it, either 32 (2A block) or 64 (2B block). However, it is
+    also possible to find receivers which can scroll strings sized as 32
+    x N or 64 x N characters. So, this control must be configured with

+
+``V4L2_CID_RDS_RX_TRAFFIC_ANNOUNCEMENT (boolean)``
+    If set, then a traffic announcement is in progress.

+    If set, then the tuned programme carries traffic announcements.
+
+``V4L2_CID_RDS_RX_MUSIC_SPEECH (boolean)``
+    If set, then this channel broadcasts music. If cleared, then it
+    broadcasts speech. If the transmitter doesn't make this distinction,
+    then it will be set.
+
+``V4L2_CID_TUNE_DEEMPHASIS (enum v4l2_deemphasis)``
+    Configures the de-emphasis value for reception. A de-emphasis filter
+    is applied to the broadcast to accentuate the high audio
+    frequencies. Depending on the region, a time constant of either 50
+    or 75 useconds is used. The enum v4l2_deemphasis defines possible

+
+.. _rf-tuner-controls:
+
+RF Tuner Control Reference
+==========================
+
+The RF Tuner (RF_TUNER) class includes controls for common features of
+devices having RF tuner.
+
+In this context, RF tuner is radio receiver circuit between antenna and
+demodulator. It receives radio frequency (RF) from the antenna and
+converts that received signal to lower intermediate frequency (IF) or
+baseband frequency (BB). Tuners that could do baseband output are often
+called Zero-IF tuners. Older tuners were typically simple PLL tuners
+inside a metal box, whilst newer ones are highly integrated chips
+without a metal box "silicon tuners". These controls are mostly
+applicable for new feature rich silicon tuners, just because older
+tuners does not have much adjustable features.
+
+For more information about RF tuners see
+`Tuner (radio) <http://en.wikipedia.org/wiki/Tuner_%28radio%29>`__
+and `RF front end <http://en.wikipedia.org/wiki/RF_front_end>`__

+
+``V4L2_CID_RF_TUNER_BANDWIDTH (integer)``
+    Filter(s) on tuner signal path are used to filter signal according
+    to receiving party needs. Driver configures filters to fulfill

+    V4L2_CID_RF_TUNER_BANDWIDTH_AUTO is not set. Unit is in Hz. The
+    range and step are driver-specific.
+
+``V4L2_CID_RF_TUNER_LNA_GAIN_AUTO (boolean)``
+    Enables/disables LNA automatic gain control (AGC)
+
+``V4L2_CID_RF_TUNER_MIXER_GAIN_AUTO (boolean)``
+    Enables/disables mixer automatic gain control (AGC)

+    Enables/disables IF automatic gain control (AGC)
+
+``V4L2_CID_RF_TUNER_RF_GAIN (integer)``
+    The RF amplifier is the very first amplifier on the receiver signal
+    path, just right after the antenna input. The difference between the
+    LNA gain and the RF gain in this document is that the LNA gain is
+    integrated in the tuner chip while the RF gain is a separate chip.
+    There may be both RF and LNA gain controls in the same device. The
+    range and step are driver-specific.
+
+``V4L2_CID_RF_TUNER_LNA_GAIN (integer)``
+    LNA (low noise amplifier) gain is first gain stage on the RF tuner
+    signal path. It is located very close to tuner antenna input. Used
+    when ``V4L2_CID_RF_TUNER_LNA_GAIN_AUTO`` is not set. See
+    ``V4L2_CID_RF_TUNER_RF_GAIN`` to understand how RF gain and LNA gain
+    differs from the each others. The range and step are
+    driver-specific.
+
+``V4L2_CID_RF_TUNER_MIXER_GAIN (integer)``
+    Mixer gain is second gain stage on the RF tuner signal path. It is
+    located inside mixer block, where RF signal is down-converted by the
+    mixer. Used when ``V4L2_CID_RF_TUNER_MIXER_GAIN_AUTO`` is not set.
+    The range and step are driver-specific.
+
+``V4L2_CID_RF_TUNER_IF_GAIN (integer)``
+    IF gain is last gain stage on the RF tuner signal path. It is
+    located on output of RF tuner. It controls signal level of

+    are driver-specific.
+
+``V4L2_CID_RF_TUNER_PLL_LOCK (boolean)``
+    Is synthesizer PLL locked? RF tuner is receiving given frequency
+    when that control is set. This is a read-only control.

+***********
+Field Order
+***********
+
+We have to distinguish between progressive and interlaced video.
+Progressive video transmits all lines of a video image sequentially.
+Interlaced video divides an image into two fields, containing only the
+odd and even lines of the image, respectively. Alternating the so called
+odd and even field are transmitted, and due to a small delay between
+fields a cathode ray TV displays the lines interleaved, yielding the
+original frame. This curious technique was invented because at refresh
+rates similar to film the image would fade out too quickly. Transmitting
+fields reduces the flicker without the necessity of doubling the frame
+rate and with it the bandwidth required for each channel.
+
+It is important to understand a video camera does not expose one frame
+at a time, merely transmitting the frames separated into fields. The
+fields are in fact captured at two different instances in time. An
+object on screen may well move between one field and the next. For
+applications analysing motion it is of paramount importance to recognize
+which field of a frame is older, the *temporal order*.
+
+When the driver provides or accepts images field by field rather than
+interleaved, it is also important applications understand how the fields
+combine to frames. We distinguish between top (aka odd) and bottom (aka
+even) fields, the *spatial order*: The first line of the top field is
+the first line of an interlaced frame, the first line of the bottom
+field is the second line of that frame.
+
+However because fields were captured one after the other, arguing
+whether a frame commences with the top or bottom field is pointless. Any
+two successive top and bottom, or bottom and top fields yield a valid
+frame. Only when the source was progressive to begin with, e. g. when
+transferring film to video, two fields may come from the same frame,
+creating a natural order.
+
+Counter to intuition the top field is not necessarily the older field.
+Whether the older field contains the top or bottom lines is a convention
+determined by the video standard. Hence the distinction between temporal
+and spatial order of fields. The diagrams below should make this
+clearer.
+
+All video capture and output devices must report the current field
+order. Some drivers may permit the selection of a different order, to
+this end applications initialize the ``field`` field of struct
+:ref:`v4l2_pix_format <v4l2-pix-format>` before calling the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. If this is not desired it
+should have the value ``V4L2_FIELD_ANY`` (0).

+Data Formats
+************
+
+
+Data Format Negotiation
+=======================
+
+Different devices exchange different kinds of data with applications,
+for example video images, raw or sliced VBI data, RDS datagrams. Even
+within one kind many different formats are possible, in particular an
+abundance of image formats. Although drivers must provide a default and
+the selection persists across closing and reopening a device,
+applications should always negotiate a data format before engaging in
+data exchange. Negotiation means the application asks for a particular
+format and the driver selects and reports the best the hardware can do
+to satisfy the request. Of course applications can also just query the
+current selection.
+
+A single mechanism exists to negotiate all data formats using the
+aggregate struct :ref:`v4l2_format <v4l2-format>` and the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls. Additionally the
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl can be used to examine
+what the hardware *could* do, without actually selecting a new data
+format. The data formats supported by the V4L2 API are covered in the
+respective device section in :ref:`devices`. For a closer look at
+image formats see :ref:`pixfmt`.
+
+The :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl is a major turning-point in the
+initialization sequence. Prior to this point multiple panel applications
+can access the same device concurrently to select the current input,
+change controls or modify other properties. The first :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+assigns a logical stream (video data, VBI data etc.) exclusively to one
+file descriptor.
+
+Exclusive means no other application, more precisely no other file
+descriptor, can grab this stream or change device properties
+inconsistent with the negotiated parameters. A video standard change for
+example, when the new standard uses a different number of scan lines,
+can invalidate the selected image format. Therefore only the file
+descriptor owning the stream can make invalidating changes. Accordingly
+multiple file descriptors which grabbed different logical streams
+prevent each other from interfering with their settings. When for
+example video overlay is about to start or already in progress,
+simultaneous video capturing may be restricted to the same cropping and
+image size.
+
+When applications omit the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl its locking side
+effects are implied by the next step, the selection of an I/O method
+with the :ref:`VIDIOC_REQBUFS` ioctl or implicit
+with the first :ref:`read() <func-read>` or
+:ref:`write() <func-write>` call.
+
+Generally only one logical stream can be assigned to a file descriptor,
+the exception being drivers permitting simultaneous video capturing and
+overlay using the same file descriptor for compatibility with V4L and
+earlier versions of V4L2. Switching the logical stream or returning into
+"panel mode" is possible by closing and reopening the device. Drivers
+*may* support a switch using :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`.
+
+All drivers exchanging data with applications must support the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. Implementation of the
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` is highly recommended but optional.
+
+
+Image Format Enumeration
+========================
+
+Apart of the generic format negotiation functions a special ioctl to
+enumerate all image formats supported by video capture, overlay or
+output devices is available. [#f1]_
+
+The :ref:`VIDIOC_ENUM_FMT` ioctl must be supported
+by all drivers exchanging image data with applications.
+
+    **Important**
+
+    Drivers are not supposed to convert image formats in kernel space.
+    They must enumerate only formats directly supported by the hardware.
+    If necessary driver writers should publish an example conversion
+    routine or library for integration into applications.
+
+.. [#f1]
+   Enumerating formats an application has no a-priori knowledge of
+   (otherwise it could explicitly ask for them and need not enumerate)
+   seems useless, but there are applications serving as proxy between
+   drivers and the actual video applications for which this is useful.

+Description
+===========
+
+The :ref:`ioctl() <func-ioctl>` function is used to program V4L2 devices. The
+argument ``fd`` must be an open file descriptor. An ioctl ``request``
+has encoded in it whether the argument is an input, output or read/write
+parameter, and the size of the argument ``argp`` in bytes. Macros and
+defines specifying V4L2 ioctl requests are located in the
+``videodev2.h`` header file. Applications should use their own copy, not
+include the version in the kernel sources on the system they compile on.
+All V4L2 ioctl requests, their respective function and parameters are
+specified in :ref:`user-func`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+When an ioctl that takes an output or read/write parameter fails, the
+parameter remains unmodified.

+v4l2-mmap - Map device memory into application address space
+
+
+Synopsis
+========
+

+
+    #include <unistd.h>
+    #include <sys/mman.h>
+
+
+.. cpp:function:: void *mmap( void *start, size_t length, int prot, int flags, int fd, off_t offset )
+
+
+Arguments
+=========
+
+``start``
+    Map the buffer to this address in the application's address space.
+    When the ``MAP_FIXED`` flag is specified, ``start`` must be a
+    multiple of the pagesize and mmap will fail when the specified
+    address cannot be used. Use of this option is discouraged;
+    applications should just specify a ``NULL`` pointer here.
+
+``length``
+    Length of the memory area to map. This must be the same value as
+    returned by the driver in the struct
+    :ref:`v4l2_buffer <v4l2-buffer>` ``length`` field for the
+    single-planar API, and the same value as returned by the driver in
+    the struct :ref:`v4l2_plane <v4l2-plane>` ``length`` field for
+    the multi-planar API.
+
+``prot``
+    The ``prot`` argument describes the desired memory protection.
+    Regardless of the device type and the direction of data exchange it
+    should be set to ``PROT_READ`` | ``PROT_WRITE``, permitting read
+    and write access to image buffers. Drivers should support at least
+    this combination of flags.
+
+    .. note::
+
+      #. The Linux ``videobuf`` kernel module, which is used by some
+	 drivers supports only ``PROT_READ`` | ``PROT_WRITE``. When the
+	 driver does not support the desired protection, the
+	 :ref:`mmap() <func-mmap>` function fails.
+
+      #. Device memory accesses (e. g. the memory on a graphics card
+	 with video capturing hardware) may incur a performance penalty
+	 compared to main memory accesses, or reads may be significantly
+	 slower than writes or vice versa. Other I/O methods may be more
+	 efficient in such case.
+
+``flags``
+    The ``flags`` parameter specifies the type of the mapped object,
+    mapping options and whether modifications made to the mapped copy of
+    the page are private to the process or are to be shared with other
+    references.
+
+    ``MAP_FIXED`` requests that the driver selects no other address than
+    the one specified. If the specified address cannot be used,
+    :ref:`mmap() <func-mmap>` will fail. If ``MAP_FIXED`` is specified,
+    ``start`` must be a multiple of the pagesize. Use of this option is
+    discouraged.
+
+    One of the ``MAP_SHARED`` or ``MAP_PRIVATE`` flags must be set.
+    ``MAP_SHARED`` allows applications to share the mapped memory with
+    other (e. g. child-) processes.
+
+    .. note:: The Linux ``videobuf`` module  which is used by some
+       drivers supports only ``MAP_SHARED``. ``MAP_PRIVATE`` requests
+       copy-on-write semantics. V4L2 applications should not set the
+       ``MAP_PRIVATE``, ``MAP_DENYWRITE``, ``MAP_EXECUTABLE`` or ``MAP_ANON``
+       flags.
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``offset``
+    Offset of the buffer in device memory. This must be the same value
+    as returned by the driver in the struct
+    :ref:`v4l2_buffer <v4l2-buffer>` ``m`` union ``offset`` field for
+    the single-planar API, and the same value as returned by the driver
+    in the struct :ref:`v4l2_plane <v4l2-plane>` ``m`` union
+    ``mem_offset`` field for the multi-planar API.
+
+
+Description
+===========
+
+The :ref:`mmap() <func-mmap>` function asks to map ``length`` bytes starting at
+``offset`` in the memory of the device specified by ``fd`` into the
+application address space, preferably at address ``start``. This latter
+address is a hint only, and is usually specified as 0.
+
+Suitable length and offset parameters are queried with the
+:ref:`VIDIOC_QUERYBUF` ioctl. Buffers must be
+allocated with the :ref:`VIDIOC_REQBUFS` ioctl
+before they can be queried.
+
+To unmap buffers the :ref:`munmap() <func-munmap>` function is used.
+
+
+Return Value
+============
+
+On success :ref:`mmap() <func-mmap>` returns a pointer to the mapped buffer. On
+error ``MAP_FAILED`` (-1) is returned, and the ``errno`` variable is set
+appropriately. Possible error codes are:
+
+EBADF
+    ``fd`` is not a valid file descriptor.
+
+EACCES
+    ``fd`` is not open for reading and writing.
+
+EINVAL
+    The ``start`` or ``length`` or ``offset`` are not suitable. (E. g.
+    they are too large, or not aligned on a ``PAGESIZE`` boundary.)
+
+    The ``flags`` or ``prot`` value is not supported.
+
+    No buffers have been allocated with the
+    :ref:`VIDIOC_REQBUFS` ioctl.
+
+ENOMEM
+    Not enough physical or virtual memory was available to complete the
+    request.

+
+Description
+===========
+
+With the :ref:`poll() <func-poll>` function applications can suspend execution
+until the driver has captured data or is ready to accept data for
+output.
+
+When streaming I/O has been negotiated this function waits until a
+buffer has been filled by the capture device and can be dequeued with
+the :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. For output devices this
+function waits until the device is ready to accept a new buffer to be
+queued up with the :ref:`VIDIOC_QBUF` ioctl for
+display. When buffers are already in the outgoing queue of the driver
+(capture) or the incoming queue isn't full (display) the function
+returns immediately.
+
+On success :ref:`poll() <func-poll>` returns the number of file descriptors
+that have been selected (that is, file descriptors for which the
+``revents`` field of the respective :c:func:`struct pollfd` structure
+is non-zero). Capture devices set the ``POLLIN`` and ``POLLRDNORM``
+flags in the ``revents`` field, output devices the ``POLLOUT`` and
+``POLLWRNORM`` flags. When the function timed out it returns a value of
+zero, on failure it returns -1 and the ``errno`` variable is set
+appropriately. When the application did not call
+:ref:`VIDIOC_STREAMON` the :ref:`poll() <func-poll>`
+function succeeds, but sets the ``POLLERR`` flag in the ``revents``
+field. When the application has called
+:ref:`VIDIOC_STREAMON` for a capture device but
+hasn't yet called :ref:`VIDIOC_QBUF`, the
+:ref:`poll() <func-poll>` function succeeds and sets the ``POLLERR`` flag in
+the ``revents`` field. For output devices this same situation will cause
+:ref:`poll() <func-poll>` to succeed as well, but it sets the ``POLLOUT`` and
+``POLLWRNORM`` flags in the ``revents`` field.
+
+If an event occurred (see :ref:`VIDIOC_DQEVENT`)
+then ``POLLPRI`` will be set in the ``revents`` field and
+:ref:`poll() <func-poll>` will return.
+
+When use of the :ref:`read() <func-read>` function has been negotiated and the
+driver does not capture yet, the :ref:`poll() <func-poll>` function starts
+capturing. When that fails it returns a ``POLLERR`` as above. Otherwise
+it waits until data has been captured and can be read. When the driver
+captures continuously (as opposed to, for example, still images) the
+function may return immediately.
+
+When use of the :ref:`write() <func-write>` function has been negotiated and the
+driver does not stream yet, the :ref:`poll() <func-poll>` function starts
+streaming. When that fails it returns a ``POLLERR`` as above. Otherwise
+it waits until the driver is ready for a non-blocking
+:ref:`write() <func-write>` call.
+
+If the caller is only interested in events (just ``POLLPRI`` is set in
+the ``events`` field), then :ref:`poll() <func-poll>` will *not* start
+streaming if the driver does not stream yet. This makes it possible to
+just poll for events and not for buffers.
+
+All drivers implementing the :ref:`read() <func-read>` or :ref:`write() <func-write>`
+function or streaming I/O must also support the :ref:`poll() <func-poll>`
+function.
+
+For more details see the :ref:`poll() <func-poll>` manual page.
+
+
+Return Value
+============
+
+On success, :ref:`poll() <func-poll>` returns the number structures which have
+non-zero ``revents`` fields, or zero if the call timed out. On error -1
+is returned, and the ``errno`` variable is set appropriately:
+
+EBADF
+    One or more of the ``ufds`` members specify an invalid file
+    descriptor.
+
+EBUSY
+    The driver does not support multiple read or write streams and the
+    device is already in use.
+
+EFAULT
+    ``ufds`` references an inaccessible memory area.
+
+EINTR
+    The call was interrupted by a signal.
+
+EINVAL
+    The ``nfds`` argument is greater than ``OPEN_MAX``.

+Synopsis
+========
+
+.. code-block:: c
+
+    #include <unistd.h>
+
+
+.. cpp:function:: ssize_t read( int fd, void *buf, size_t count )
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``buf``
+``count``
+
+
+Description
+===========
+
+:ref:`read() <func-read>` attempts to read up to ``count`` bytes from file
+descriptor ``fd`` into the buffer starting at ``buf``. The layout of the
+data in the buffer is discussed in the respective device interface
+section, see ##. If ``count`` is zero, :ref:`read() <func-read>` returns zero
+and has no other results. If ``count`` is greater than ``SSIZE_MAX``,
+the result is unspecified. Regardless of the ``count`` value each
+:ref:`read() <func-read>` call will provide at most one frame (two fields)
+worth of data.
+
+By default :ref:`read() <func-read>` blocks until data becomes available. When
+the ``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>`
+function it returns immediately with an ``EAGAIN`` error code when no data
+is available. The :ref:`select() <func-select>` or
+:ref:`poll() <func-poll>` functions can always be used to suspend
+execution until data becomes available. All drivers supporting the
+:ref:`read() <func-read>` function must also support :ref:`select() <func-select>` and
+:ref:`poll() <func-poll>`.
+
+Drivers can implement read functionality in different ways, using a
+single or multiple buffers and discarding the oldest or newest frames
+once the internal buffers are filled.
+
+:ref:`read() <func-read>` never returns a "snapshot" of a buffer being filled.
+Using a single buffer the driver will stop capturing when the
+application starts reading the buffer until the read is finished. Thus
+only the period of the vertical blanking interval is available for
+reading, or the capture rate must fall below the nominal frame rate of
+the video standard.
+
+The behavior of :ref:`read() <func-read>` when called during the active picture
+period or the vertical blanking separating the top and bottom field
+depends on the discarding policy. A driver discarding the oldest frames
+keeps capturing into an internal buffer, continuously overwriting the
+previously, not read frame, and returns the frame being received at the
+time of the :ref:`read() <func-read>` call as soon as it is complete.
+
+A driver discarding the newest frames stops capturing until the next
+:ref:`read() <func-read>` call. The frame being received at :ref:`read() <func-read>`
+time is discarded, returning the following frame instead. Again this
+implies a reduction of the capture rate to one half or less of the
+nominal frame rate. An example of this model is the video read mode of
+the bttv driver, initiating a DMA to user memory when :ref:`read() <func-read>`
+is called and returning when the DMA finished.
+
+In the multiple buffer model drivers maintain a ring of internal
+buffers, automatically advancing to the next free buffer. This allows
+continuous capturing when the application can empty the buffers fast
+enough. Again, the behavior when the driver runs out of free buffers
+depends on the discarding policy.
+
+Applications can get and set the number of buffers used internally by
+the driver with the :ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and
+:ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctls. They are optional,
+however. The discarding policy is not reported and cannot be changed.
+For minimum requirements see :ref:`devices`.
+
+
+Return Value
+============
+
+On success, the number of bytes read is returned. It is not an error if
+this number is smaller than the number of bytes requested, or the amount
+of data required for one frame. This may happen for example because
+:ref:`read() <func-read>` was interrupted by a signal. On error, -1 is
+returned, and the ``errno`` variable is set appropriately. In this case
+the next read will start at the beginning of a new frame. Possible error
+codes are:
+
+EAGAIN
+    Non-blocking I/O has been selected using O_NONBLOCK and no data was
+    immediately available for reading.
+
+EBADF
+    ``fd`` is not a valid file descriptor or is not open for reading, or
+    the process already has the maximum number of files open.
+
+EBUSY
+    The driver does not support multiple read streams and the device is
+    already in use.
+
+EFAULT
+    ``buf`` references an inaccessible memory area.
+
+EINTR
+    The call was interrupted by a signal before any data was read.
+
+EIO
+    I/O error. This indicates some hardware problem or a failure to
+    communicate with a remote device (USB camera etc.).
+
+EINVAL
+    The :ref:`read() <func-read>` function is not supported by this driver, not
+    on this device, or generally not on this type of device.

+
+
+Description
+===========
+
+With the :ref:`select() <func-select>` function applications can suspend
+execution until the driver has captured data or is ready to accept data
+for output.
+
+When streaming I/O has been negotiated this function waits until a
+buffer has been filled or displayed and can be dequeued with the

+the outgoing queue of the driver the function returns immediately.
+
+On success :ref:`select() <func-select>` returns the total number of bits set in
+:c:func:`struct fd_set`. When the function timed out it returns
+a value of zero. On failure it returns -1 and the ``errno`` variable is
+set appropriately. When the application did not call
+:ref:`VIDIOC_QBUF` or
+:ref:`VIDIOC_STREAMON` yet the :ref:`select() <func-select>`
+function succeeds, setting the bit of the file descriptor in ``readfds``
+or ``writefds``, but subsequent :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`
+calls will fail. [#f1]_
+
+When use of the :ref:`read() <func-read>` function has been negotiated and the
+driver does not capture yet, the :ref:`select() <func-select>` function starts
+capturing. When that fails, :ref:`select() <func-select>` returns successful and
+a subsequent :ref:`read() <func-read>` call, which also attempts to start
+capturing, will return an appropriate error code. When the driver
+captures continuously (as opposed to, for example, still images) and
+data is already available the :ref:`select() <func-select>` function returns
+immediately.
+
+When use of the :ref:`write() <func-write>` function has been negotiated the
+:ref:`select() <func-select>` function just waits until the driver is ready for a
+non-blocking :ref:`write() <func-write>` call.
+
+All drivers implementing the :ref:`read() <func-read>` or :ref:`write() <func-write>`
+function or streaming I/O must also support the :ref:`select() <func-select>`
+function.
+
+For more details see the :ref:`select() <func-select>` manual page.
+
+
+Return Value
+============
+
+On success, :ref:`select() <func-select>` returns the number of descriptors
+contained in the three returned descriptor sets, which will be zero if
+the timeout expired. On error -1 is returned, and the ``errno`` variable
+is set appropriately; the sets and ``timeout`` are undefined. Possible

+***********************
+Changes of the V4L2 API
+***********************
+
+Soon after the V4L API was added to the kernel it was criticised as too
+inflexible. In August 1998 Bill Dirks proposed a number of improvements
+and began to work on documentation, example drivers and applications.
+With the help of other volunteers this eventually became the V4L2 API,
+not just an extension but a replacement for the V4L API. However it took
+another four years and two stable kernel releases until the new API was
+finally accepted for inclusion into the kernel in its present form.
+
+
+Early Versions
+==============
+
+1998-08-20: First version.
+
+1998-08-27: The :ref:`select() <func-select>` function was introduced.
+
+1998-09-10: New video standard interface.
+
+1998-09-18: The ``VIDIOC_NONCAP`` ioctl was replaced by the otherwise
+meaningless ``O_TRUNC`` :ref:`open() <func-open>` flag, and the
+aliases ``O_NONCAP`` and ``O_NOIO`` were defined. Applications can set
+this flag if they intend to access controls only, as opposed to capture
+applications which need exclusive access. The ``VIDEO_STD_XXX``
+identifiers are now ordinals instead of flags, and the
+:c:func:`video_std_construct()` helper function takes id and
+transmission arguments.
+
+1998-09-28: Revamped video standard. Made video controls individually
+enumerable.
+
+1998-10-02: The ``id`` field was removed from struct
+:c:type:`struct video_standard` and the color subcarrier fields were
+renamed. The :ref:`VIDIOC_QUERYSTD` ioctl was
+renamed to :ref:`VIDIOC_ENUMSTD`,
+:ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` to
+:ref:`VIDIOC_ENUMINPUT`. A first draft of the
+Codec API was released.
+
+1998-11-08: Many minor changes. Most symbols have been renamed. Some
+material changes to struct :ref:`v4l2_capability <v4l2-capability>`.
+
+1998-11-12: The read/write directon of some ioctls was misdefined.
+
+1998-11-14: ``V4L2_PIX_FMT_RGB24`` changed to ``V4L2_PIX_FMT_BGR24``,
+and ``V4L2_PIX_FMT_RGB32`` changed to ``V4L2_PIX_FMT_BGR32``. Audio
+controls are now accessible with the
+:ref:`VIDIOC_G_CTRL <VIDIOC_G_CTRL>` and
+:ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls under names starting
+with ``V4L2_CID_AUDIO``. The ``V4L2_MAJOR`` define was removed from
+``videodev.h`` since it was only used once in the ``videodev`` kernel
+module. The ``YUV422`` and ``YUV411`` planar image formats were added.
+
+1998-11-28: A few ioctl symbols changed. Interfaces for codecs and video
+output devices were added.
+
+1999-01-14: A raw VBI capture interface was added.
+
+1999-01-19: The ``VIDIOC_NEXTBUF`` ioctl was removed.
+
+
+V4L2 Version 0.16 1999-01-31
+============================
+
+1999-01-27: There is now one QBUF ioctl, VIDIOC_QWBUF and VIDIOC_QRBUF
+are gone. VIDIOC_QBUF takes a v4l2_buffer as a parameter. Added
+digital zoom (cropping) controls.
+
+
+V4L2 Version 0.18 1999-03-16
+============================
+
+Added a v4l to V4L2 ioctl compatibility layer to videodev.c. Driver
+writers, this changes how you implement your ioctl handler. See the
+Driver Writer's Guide. Added some more control id codes.
+
+
+V4L2 Version 0.19 1999-06-05
+============================
+
+1999-03-18: Fill in the category and catname fields of v4l2_queryctrl
+objects before passing them to the driver. Required a minor change to
+the VIDIOC_QUERYCTRL handlers in the sample drivers.
+
+1999-03-31: Better compatibility for v4l memory capture ioctls. Requires
+changes to drivers to fully support new compatibility features, see
+Driver Writer's Guide and v4l2cap.c. Added new control IDs:
+V4L2_CID_HFLIP, _VFLIP. Changed V4L2_PIX_FMT_YUV422P to _YUV422P,
+and _YUV411P to _YUV411P.
+
+1999-04-04: Added a few more control IDs.
+
+1999-04-07: Added the button control type.
+
+1999-05-02: Fixed a typo in videodev.h, and added the
+V4L2_CTRL_FLAG_GRAYED (later V4L2_CTRL_FLAG_GRABBED) flag.
+
+1999-05-20: Definition of VIDIOC_G_CTRL was wrong causing a
+malfunction of this ioctl.
+
+1999-06-05: Changed the value of V4L2_CID_WHITENESS.
+
+
+V4L2 Version 0.20 (1999-09-10)
+==============================
+
+Version 0.20 introduced a number of changes which were *not backward
+compatible* with 0.19 and earlier versions. Purpose of these changes was
+to simplify the API, while making it more extensible and following
+common Linux driver API conventions.
+
+1. Some typos in ``V4L2_FMT_FLAG`` symbols were fixed. struct
+   :ref:`v4l2_clip <v4l2-clip>` was changed for compatibility with
+   v4l. (1999-08-30)
+
+2. ``V4L2_TUNER_SUB_LANG1`` was added. (1999-09-05)
+
+3. All ioctl() commands that used an integer argument now take a pointer
+   to an integer. Where it makes sense, ioctls will return the actual
+   new value in the integer pointed to by the argument, a common
+   convention in the V4L2 API. The affected ioctls are: VIDIOC_PREVIEW,
+   VIDIOC_STREAMON, VIDIOC_STREAMOFF, VIDIOC_S_FREQ,
+   VIDIOC_S_INPUT, VIDIOC_S_OUTPUT, VIDIOC_S_EFFECT. For example
+
+
+   .. code-block:: c
+
+       err = ioctl (fd, VIDIOC_XXX, V4L2_XXX);
+
+   becomes
+
+
+   .. code-block:: c
+
+       int a = V4L2_XXX; err = ioctl(fd, VIDIOC_XXX, &a);
+
+4. All the different get- and set-format commands were swept into one
+   :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+   :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl taking a union and a
+   type field selecting the union member as parameter. Purpose is to
+   simplify the API by eliminating several ioctls and to allow new and
+   driver private data streams without adding new ioctls.
+
+   This change obsoletes the following ioctls: ``VIDIOC_S_INFMT``,
+   ``VIDIOC_G_INFMT``, ``VIDIOC_S_OUTFMT``, ``VIDIOC_G_OUTFMT``,
+   ``VIDIOC_S_VBIFMT`` and ``VIDIOC_G_VBIFMT``. The image format
+   structure :c:type:`struct v4l2_format` was renamed to struct
+   :ref:`v4l2_pix_format <v4l2-pix-format>`, while struct
+   :ref:`v4l2_format <v4l2-format>` is now the envelopping structure
+   for all format negotiations.
+
+5. Similar to the changes above, the ``VIDIOC_G_PARM`` and
+   ``VIDIOC_S_PARM`` ioctls were merged with ``VIDIOC_G_OUTPARM`` and
+   ``VIDIOC_S_OUTPARM``. A ``type`` field in the new struct
+   :ref:`v4l2_streamparm <v4l2-streamparm>` selects the respective
+   union member.
+
+   This change obsoletes the ``VIDIOC_G_OUTPARM`` and
+   ``VIDIOC_S_OUTPARM`` ioctls.
+
+6. Control enumeration was simplified, and two new control flags were
+   introduced and one dropped. The ``catname`` field was replaced by a
+   ``group`` field.
+
+   Drivers can now flag unsupported and temporarily unavailable controls
+   with ``V4L2_CTRL_FLAG_DISABLED`` and ``V4L2_CTRL_FLAG_GRABBED``
+   respectively. The ``group`` name indicates a possibly narrower
+   classification than the ``category``. In other words, there may be
+   multiple groups within a category. Controls within a group would
+   typically be drawn within a group box. Controls in different
+   categories might have a greater separation, or may even appear in
+   separate windows.
+
+7. The struct :ref:`v4l2_buffer <v4l2-buffer>` ``timestamp`` was
+   changed to a 64 bit integer, containing the sampling or output time
+   of the frame in nanoseconds. Additionally timestamps will be in
+   absolute system time, not starting from zero at the beginning of a
+   stream. The data type name for timestamps is stamp_t, defined as a
+   signed 64-bit integer. Output devices should not send a buffer out
+   until the time in the timestamp field has arrived. I would like to
+   follow SGI's lead, and adopt a multimedia timestamping system like
+   their UST (Unadjusted System Time). See
+   http://web.archive.org/web/\*/http://reality.sgi.com
+   /cpirazzi_engr/lg/time/intro.html. UST uses timestamps that are
+   64-bit signed integers (not struct timeval's) and given in nanosecond
+   units. The UST clock starts at zero when the system is booted and
+   runs continuously and uniformly. It takes a little over 292 years for
+   UST to overflow. There is no way to set the UST clock. The regular
+   Linux time-of-day clock can be changed periodically, which would
+   cause errors if it were being used for timestamping a multimedia
+   stream. A real UST style clock will require some support in the
+   kernel that is not there yet. But in anticipation, I will change the
+   timestamp field to a 64-bit integer, and I will change the
+   v4l2_masterclock_gettime() function (used only by drivers) to
+   return a 64-bit integer.
+
+8. A ``sequence`` field was added to struct
+   :ref:`v4l2_buffer <v4l2-buffer>`. The ``sequence`` field counts
+   captured frames, it is ignored by output devices. When a capture
+   driver drops a frame, the sequence number of that frame is skipped.
+
+
+V4L2 Version 0.20 incremental changes
+=====================================
+
+1999-12-23: In struct :ref:`v4l2_vbi_format <v4l2-vbi-format>` the
+``reserved1`` field became ``offset``. Previously drivers were required
+to clear the ``reserved1`` field.
+
+2000-01-13: The ``V4L2_FMT_FLAG_NOT_INTERLACED`` flag was added.
+
+2000-07-31: The ``linux/poll.h`` header is now included by
+``videodev.h`` for compatibility with the original ``videodev.h`` file.
+
+2000-11-20: ``V4L2_TYPE_VBI_OUTPUT`` and ``V4L2_PIX_FMT_Y41P`` were
+added.
+
+2000-11-25: ``V4L2_TYPE_VBI_INPUT`` was added.
+
+2000-12-04: A couple typos in symbol names were fixed.
+
+2001-01-18: To avoid namespace conflicts the ``fourcc`` macro defined in
+the ``videodev.h`` header file was renamed to ``v4l2_fourcc``.
+
+2001-01-25: A possible driver-level compatibility problem between the
+``videodev.h`` file in Linux 2.4.0 and the ``videodev.h`` file included
+in the ``videodevX`` patch was fixed. Users of an earlier version of
+``videodevX`` on Linux 2.4.0 should recompile their V4L and V4L2
+drivers.
+
+2001-01-26: A possible kernel-level incompatibility between the
+``videodev.h`` file in the ``videodevX`` patch and the ``videodev.h``
+file in Linux 2.2.x with devfs patches applied was fixed.
+
+2001-03-02: Certain V4L ioctls which pass data in both direction
+although they are defined with read-only parameter, did not work
+correctly through the backward compatibility layer. [Solution?]
+
+2001-04-13: Big endian 16-bit RGB formats were added.
+
+2001-09-17: New YUV formats and the
+:ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctls were added.
+(The old ``VIDIOC_G_FREQ`` and ``VIDIOC_S_FREQ`` ioctls did not take
+multiple tuners into account.)
+
+2000-09-18: ``V4L2_BUF_TYPE_VBI`` was added. This may *break
+compatibility* as the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctls may fail now if the struct
+:c:type:`struct v4l2_fmt` ``type`` field does not contain
+``V4L2_BUF_TYPE_VBI``. In the documentation of the struct
+:ref:`v4l2_vbi_format <v4l2-vbi-format>` ``offset`` field the
+ambiguous phrase "rising edge" was changed to "leading edge".
+
+
+V4L2 Version 0.20 2000-11-23
+============================
+
+A number of changes were made to the raw VBI interface.
+
+1. Figures clarifying the line numbering scheme were added to the V4L2
+   API specification. The ``start``\ [0] and ``start``\ [1] fields no
+   longer count line numbers beginning at zero. Rationale: a) The
+   previous definition was unclear. b) The ``start``\ [] values are
+   ordinal numbers. c) There is no point in inventing a new line
+   numbering scheme. We now use line number as defined by ITU-R, period.
+   Compatibility: Add one to the start values. Applications depending on
+   the previous semantics may not function correctly.
+
+2. The restriction "count[0] > 0 and count[1] > 0" has been relaxed to
+   "(count[0] + count[1]) > 0". Rationale: Drivers may allocate
+   resources at scan line granularity and some data services are
+   transmitted only on the first field. The comment that both ``count``
+   values will usually be equal is misleading and pointless and has been
+   removed. This change *breaks compatibility* with earlier versions:
+   Drivers may return ``EINVAL``, applications may not function correctly.
+
+3. Drivers are again permitted to return negative (unknown) start values
+   as proposed earlier. Why this feature was dropped is unclear. This
+   change may *break compatibility* with applications depending on the
+   start values being positive. The use of ``EBUSY`` and ``EINVAL``
+   error codes with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl was
+   clarified. The ``EBUSY`` error code was finally documented, and the
+   ``reserved2`` field which was previously mentioned only in the
+   ``videodev.h`` header file.
+
+4. New buffer types ``V4L2_TYPE_VBI_INPUT`` and ``V4L2_TYPE_VBI_OUTPUT``
+   were added. The former is an alias for the old ``V4L2_TYPE_VBI``, the
+   latter was missing in the ``videodev.h`` file.
+
+
+V4L2 Version 0.20 2002-07-25
+============================
+
+Added sliced VBI interface proposal.
+
+
+V4L2 in Linux 2.5.46, 2002-10
+=============================
+
+Around October-November 2002, prior to an announced feature freeze of
+Linux 2.5, the API was revised, drawing from experience with V4L2 0.20.
+This unnamed version was finally merged into Linux 2.5.46.
+
+1.  As specified in :ref:`related`, drivers must make related device
+    functions available under all minor device numbers.
+
+2.  The :ref:`open() <func-open>` function requires access mode
+    ``O_RDWR`` regardless of the device type. All V4L2 drivers
+    exchanging data with applications must support the ``O_NONBLOCK``
+    flag. The ``O_NOIO`` flag, a V4L2 symbol which aliased the
+    meaningless ``O_TRUNC`` to indicate accesses without data exchange
+    (panel applications) was dropped. Drivers must stay in "panel mode"
+    until the application attempts to initiate a data exchange, see
+    :ref:`open`.
+
+3.  The struct :ref:`v4l2_capability <v4l2-capability>` changed
+    dramatically. Note that also the size of the structure changed,
+    which is encoded in the ioctl request code, thus older V4L2 devices
+    will respond with an ``EINVAL`` error code to the new
+    :ref:`VIDIOC_QUERYCAP` ioctl.
+
+    There are new fields to identify the driver, a new RDS device
+    function ``V4L2_CAP_RDS_CAPTURE``, the ``V4L2_CAP_AUDIO`` flag
+    indicates if the device has any audio connectors, another I/O
+    capability ``V4L2_CAP_ASYNCIO`` can be flagged. In response to these
+    changes the ``type`` field became a bit set and was merged into the
+    ``flags`` field. ``V4L2_FLAG_TUNER`` was renamed to
+    ``V4L2_CAP_TUNER``, ``V4L2_CAP_VIDEO_OVERLAY`` replaced
+    ``V4L2_FLAG_PREVIEW`` and ``V4L2_CAP_VBI_CAPTURE`` and
+    ``V4L2_CAP_VBI_OUTPUT`` replaced ``V4L2_FLAG_DATA_SERVICE``.
+    ``V4L2_FLAG_READ`` and ``V4L2_FLAG_WRITE`` were merged into
+    ``V4L2_CAP_READWRITE``.
+
+    The redundant fields ``inputs``, ``outputs`` and ``audios`` were
+    removed. These properties can be determined as described in
+    :ref:`video` and :ref:`audio`.
+
+    The somewhat volatile and therefore barely useful fields
+    ``maxwidth``, ``maxheight``, ``minwidth``, ``minheight``,
+    ``maxframerate`` were removed. This information is available as
+    described in :ref:`format` and :ref:`standard`.
+
+    ``V4L2_FLAG_SELECT`` was removed. We believe the select() function
+    is important enough to require support of it in all V4L2 drivers
+    exchanging data with applications. The redundant
+    ``V4L2_FLAG_MONOCHROME`` flag was removed, this information is
+    available as described in :ref:`format`.
+
+4.  In struct :ref:`v4l2_input <v4l2-input>` the ``assoc_audio``
+    field and the ``capability`` field and its only flag
+    ``V4L2_INPUT_CAP_AUDIO`` was replaced by the new ``audioset`` field.
+    Instead of linking one video input to one audio input this field
+    reports all audio inputs this video input combines with.
+
+    New fields are ``tuner`` (reversing the former link from tuners to
+    video inputs), ``std`` and ``status``.
+
+    Accordingly struct :ref:`v4l2_output <v4l2-output>` lost its
+    ``capability`` and ``assoc_audio`` fields. ``audioset``,
+    ``modulator`` and ``std`` where added instead.
+
+5.  The struct :ref:`v4l2_audio <v4l2-audio>` field ``audio`` was
+    renamed to ``index``, for consistency with other structures. A new
+    capability flag ``V4L2_AUDCAP_STEREO`` was added to indicated if the
+    audio input in question supports stereo sound.
+    ``V4L2_AUDCAP_EFFECTS`` and the corresponding ``V4L2_AUDMODE`` flags
+    where removed. This can be easily implemented using controls.
+    (However the same applies to AVL which is still there.)
+
+    Again for consistency the struct
+    :ref:`v4l2_audioout <v4l2-audioout>` field ``audio`` was renamed
+    to ``index``.
+
+6.  The struct :ref:`v4l2_tuner <v4l2-tuner>` ``input`` field was
+    replaced by an ``index`` field, permitting devices with multiple
+    tuners. The link between video inputs and tuners is now reversed,
+    inputs point to their tuner. The ``std`` substructure became a
+    simple set (more about this below) and moved into struct
+    :ref:`v4l2_input <v4l2-input>`. A ``type`` field was added.
+
+    Accordingly in struct :ref:`v4l2_modulator <v4l2-modulator>` the
+    ``output`` was replaced by an ``index`` field.
+
+    In struct :ref:`v4l2_frequency <v4l2-frequency>` the ``port``
+    field was replaced by a ``tuner`` field containing the respective
+    tuner or modulator index number. A tuner ``type`` field was added
+    and the ``reserved`` field became larger for future extensions
+    (satellite tuners in particular).
+
+7.  The idea of completely transparent video standards was dropped.
+    Experience showed that applications must be able to work with video
+    standards beyond presenting the user a menu. Instead of enumerating
+    supported standards with an ioctl applications can now refer to
+    standards by :ref:`v4l2_std_id <v4l2-std-id>` and symbols
+    defined in the ``videodev2.h`` header file. For details see
+    :ref:`standard`. The :ref:`VIDIOC_G_STD <VIDIOC_G_STD>` and
+    :ref:`VIDIOC_S_STD <VIDIOC_G_STD>` now take a pointer to this
+    type as argument. :ref:`VIDIOC_QUERYSTD` was
+    added to autodetect the received standard, if the hardware has this
+    capability. In struct :ref:`v4l2_standard <v4l2-standard>` an
+    ``index`` field was added for
+    :ref:`VIDIOC_ENUMSTD`. A
+    :ref:`v4l2_std_id <v4l2-std-id>` field named ``id`` was added as
+    machine readable identifier, also replacing the ``transmission``
+    field. The misleading ``framerate`` field was renamed to
+    ``frameperiod``. The now obsolete ``colorstandard`` information,
+    originally needed to distguish between variations of standards, were
+    removed.
+
+    Struct :c:type:`struct v4l2_enumstd` ceased to be.
+    :ref:`VIDIOC_ENUMSTD` now takes a pointer to a
+    struct :ref:`v4l2_standard <v4l2-standard>` directly. The
+    information which standards are supported by a particular video
+    input or output moved into struct :ref:`v4l2_input <v4l2-input>`
+    and struct :ref:`v4l2_output <v4l2-output>` fields named ``std``,
+    respectively.
+
+8.  The struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` fields
+    ``category`` and ``group`` did not catch on and/or were not
+    implemented as expected and therefore removed.
+
+9.  The :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl was added to
+    negotiate data formats as with
+    :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, but without the overhead of
+    programming the hardware and regardless of I/O in progress.
+
+    In struct :ref:`v4l2_format <v4l2-format>` the ``fmt`` union was
+    extended to contain struct :ref:`v4l2_window <v4l2-window>`. All
+    image format negotiations are now possible with ``VIDIOC_G_FMT``,
+    ``VIDIOC_S_FMT`` and ``VIDIOC_TRY_FMT``; ioctl. The ``VIDIOC_G_WIN``
+    and ``VIDIOC_S_WIN`` ioctls to prepare for a video overlay were
+    removed. The ``type`` field changed to type enum
+    :ref:`v4l2_buf_type <v4l2-buf-type>` and the buffer type names
+    changed as follows.
+
+
+

+
+	   -  ``V4L2_BUF_TYPE_PRIVATE_BASE``
+
+	   -  ``V4L2_BUF_TYPE_PRIVATE`` (but this is deprecated)
+
+
+10. In struct :ref:`v4l2_fmtdesc <v4l2-fmtdesc>` a enum
+    :ref:`v4l2_buf_type <v4l2-buf-type>` field named ``type`` was
+    added as in struct :ref:`v4l2_format <v4l2-format>`. The
+    ``VIDIOC_ENUM_FBUFFMT`` ioctl is no longer needed and was removed.
+    These calls can be replaced by
+    :ref:`VIDIOC_ENUM_FMT` with type
+    ``V4L2_BUF_TYPE_VIDEO_OVERLAY``.
+
+11. In struct :ref:`v4l2_pix_format <v4l2-pix-format>` the ``depth``
+    field was removed, assuming applications which recognize the format
+    by its four-character-code already know the color depth, and others
+    do not care about it. The same rationale lead to the removal of the
+    ``V4L2_FMT_FLAG_COMPRESSED`` flag. The
+    ``V4L2_FMT_FLAG_SWCONVECOMPRESSED`` flag was removed because drivers
+    are not supposed to convert images in kernel space. A user library
+    of conversion functions should be provided instead. The
+    ``V4L2_FMT_FLAG_BYTESPERLINE`` flag was redundant. Applications can
+    set the ``bytesperline`` field to zero to get a reasonable default.
+    Since the remaining flags were replaced as well, the ``flags`` field
+    itself was removed.
+
+    The interlace flags were replaced by a enum
+    :ref:`v4l2_field <v4l2-field>` value in a newly added ``field``
+    field.
+
+
+
+    .. flat-table::
+	:header-rows:  1
+	:stub-columns: 0
+
+
+	-  .. row 1
+
+	   -  Old flag
+
+	   -  enum :ref:`v4l2_field <v4l2-field>`
+
+	-  .. row 2

+	   -  ``V4L2_FMT_FLAG_NOT_INTERLACED``
+
+	   -  ?
+
+	-  .. row 3
+
+	   -  ``V4L2_FMT_FLAG_INTERLACED`` = ``V4L2_FMT_FLAG_COMBINED``
+
+	   -  ``V4L2_FIELD_INTERLACED``
+
+	-  .. row 4
+
+	   -  ``V4L2_FMT_FLAG_TOPFIELD`` = ``V4L2_FMT_FLAG_ODDFIELD``
+
+	   -  ``V4L2_FIELD_TOP``
+

+

+
+	-  .. row 8
+
+	   -  ``-``
+
+	   -  ``V4L2_FIELD_ALTERNATE``
+
+
+    The color space flags were replaced by a enum
+    :ref:`v4l2_colorspace <v4l2-colorspace>` value in a newly added
+    ``colorspace`` field, where one of ``V4L2_COLORSPACE_SMPTE170M``,
+    ``V4L2_COLORSPACE_BT878``, ``V4L2_COLORSPACE_470_SYSTEM_M`` or
+    ``V4L2_COLORSPACE_470_SYSTEM_BG`` replaces ``V4L2_FMT_CS_601YUV``.
+
+12. In struct :ref:`v4l2_requestbuffers <v4l2-requestbuffers>` the
+    ``type`` field was properly defined as enum
+    :ref:`v4l2_buf_type <v4l2-buf-type>`. Buffer types changed as
+    mentioned above. A new ``memory`` field of type enum
+    :ref:`v4l2_memory <v4l2-memory>` was added to distinguish between
+    I/O methods using buffers allocated by the driver or the
+    application. See :ref:`io` for details.
+
+13. In struct :ref:`v4l2_buffer <v4l2-buffer>` the ``type`` field was
+    properly defined as enum :ref:`v4l2_buf_type <v4l2-buf-type>`.
+    Buffer types changed as mentioned above. A ``field`` field of type
+    enum :ref:`v4l2_field <v4l2-field>` was added to indicate if a
+    buffer contains a top or bottom field. The old field flags were
+    removed. Since no unadjusted system time clock was added to the
+    kernel as planned, the ``timestamp`` field changed back from type
+    stamp_t, an unsigned 64 bit integer expressing the sample time in
+    nanoseconds, to struct :c:type:`struct timeval`. With the addition
+    of a second memory mapping method the ``offset`` field moved into
+    union ``m``, and a new ``memory`` field of type enum
+    :ref:`v4l2_memory <v4l2-memory>` was added to distinguish between
+    I/O methods. See :ref:`io` for details.
+
+    The ``V4L2_BUF_REQ_CONTIG`` flag was used by the V4L compatibility
+    layer, after changes to this code it was no longer needed. The
+    ``V4L2_BUF_ATTR_DEVICEMEM`` flag would indicate if the buffer was
+    indeed allocated in device memory rather than DMA-able system
+    memory. It was barely useful and so was removed.
+
+14. In struct :ref:`v4l2_framebuffer <v4l2-framebuffer>` the
+    ``base[3]`` array anticipating double- and triple-buffering in
+    off-screen video memory, however without defining a synchronization
+    mechanism, was replaced by a single pointer. The
+    ``V4L2_FBUF_CAP_SCALEUP`` and ``V4L2_FBUF_CAP_SCALEDOWN`` flags were
+    removed. Applications can determine this capability more accurately
+    using the new cropping and scaling interface. The
+    ``V4L2_FBUF_CAP_CLIPPING`` flag was replaced by
+    ``V4L2_FBUF_CAP_LIST_CLIPPING`` and
+    ``V4L2_FBUF_CAP_BITMAP_CLIPPING``.
+
+15. In struct :ref:`v4l2_clip <v4l2-clip>` the ``x``, ``y``,
+    ``width`` and ``height`` field moved into a ``c`` substructure of
+    type struct :ref:`v4l2_rect <v4l2-rect>`. The ``x`` and ``y``
+    fields were renamed to ``left`` and ``top``, i. e. offsets to a
+    context dependent origin.
+
+16. In struct :ref:`v4l2_window <v4l2-window>` the ``x``, ``y``,
+    ``width`` and ``height`` field moved into a ``w`` substructure as
+    above. A ``field`` field of type %v4l2-field; was added to
+    distinguish between field and frame (interlaced) overlay.
+
+17. The digital zoom interface, including struct
+    :c:type:`struct v4l2_zoomcap`, struct
+    :c:type:`struct v4l2_zoom`, ``V4L2_ZOOM_NONCAP`` and
+    ``V4L2_ZOOM_WHILESTREAMING`` was replaced by a new cropping and
+    scaling interface. The previously unused struct
+    :c:type:`struct v4l2_cropcap` and :c:type:`struct v4l2_crop`
+    where redefined for this purpose. See :ref:`crop` for details.
+
+18. In struct :ref:`v4l2_vbi_format <v4l2-vbi-format>` the
+    ``SAMPLE_FORMAT`` field now contains a four-character-code as used
+    to identify video image formats and ``V4L2_PIX_FMT_GREY`` replaces
+    the ``V4L2_VBI_SF_UBYTE`` define. The ``reserved`` field was
+    extended.
+
+19. In struct :ref:`v4l2_captureparm <v4l2-captureparm>` the type of
+    the ``timeperframe`` field changed from unsigned long to struct
+    :ref:`v4l2_fract <v4l2-fract>`. This allows the accurate
+    expression of multiples of the NTSC-M frame rate 30000 / 1001. A new
+    field ``readbuffers`` was added to control the driver behaviour in
+    read I/O mode.
+
+    Similar changes were made to struct
+    :ref:`v4l2_outputparm <v4l2-outputparm>`.
+
+20. The struct :c:type:`struct v4l2_performance` and
+    ``VIDIOC_G_PERF`` ioctl were dropped. Except when using the
+    :ref:`read/write I/O method <rw>`, which is limited anyway, this
+    information is already available to applications.
+
+21. The example transformation from RGB to YCbCr color space in the old
+    V4L2 documentation was inaccurate, this has been corrected in
+    :ref:`pixfmt`.
+
+
+V4L2 2003-06-19
+===============
+
+1. A new capability flag ``V4L2_CAP_RADIO`` was added for radio devices.
+   Prior to this change radio devices would identify solely by having
+   exactly one tuner whose type field reads ``V4L2_TUNER_RADIO``.
+
+2. An optional driver access priority mechanism was added, see
+   :ref:`app-pri` for details.
+
+3. The audio input and output interface was found to be incomplete.
+
+   Previously the :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` ioctl would
+   enumerate the available audio inputs. An ioctl to determine the
+   current audio input, if more than one combines with the current video
+   input, did not exist. So ``VIDIOC_G_AUDIO`` was renamed to
+   ``VIDIOC_G_AUDIO_OLD``, this ioctl was removed on Kernel 2.6.39. The
+   :ref:`VIDIOC_ENUMAUDIO` ioctl was added to
+   enumerate audio inputs, while
+   :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` now reports the current
+   audio input.
+
+   The same changes were made to
+   :ref:`VIDIOC_G_AUDOUT <VIDIOC_G_AUDOUT>` and
+   :ref:`VIDIOC_ENUMAUDOUT <VIDIOC_ENUMAUDOUT>`.
+
+   Until further the "videodev" module will automatically translate
+   between the old and new ioctls, but drivers and applications must be
+   updated to successfully compile again.
+
+4. The :ref:`VIDIOC_OVERLAY` ioctl was incorrectly
+   defined with write-read parameter. It was changed to write-only,
+   while the write-read version was renamed to ``VIDIOC_OVERLAY_OLD``.
+   The old ioctl was removed on Kernel 2.6.39. Until further the
+   "videodev" kernel module will automatically translate to the new
+   version, so drivers must be recompiled, but not applications.
+
+5. :ref:`overlay` incorrectly stated that clipping rectangles define
+   regions where the video can be seen. Correct is that clipping
+   rectangles define regions where *no* video shall be displayed and so
+   the graphics surface can be seen.
+
+6. The :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` and
+   :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` ioctls were defined with
+   write-only parameter, inconsistent with other ioctls modifying their
+   argument. They were changed to write-read, while a ``_OLD`` suffix
+   was added to the write-only versions. The old ioctls were removed on
+   Kernel 2.6.39. Drivers and applications assuming a constant parameter
+   need an update.
+
+
+V4L2 2003-11-05
+===============
+
+1. In :ref:`pixfmt-rgb` the following pixel formats were incorrectly
+   transferred from Bill Dirks' V4L2 specification. Descriptions below
+   refer to bytes in memory, in ascending address order.

+
+   The ``V4L2_PIX_FMT_BGR24`` example was always correct.
+
+   In :ref:`v4l-image-properties` the mapping of the V4L
+   ``VIDEO_PALETTE_RGB24`` and ``VIDEO_PALETTE_RGB32`` formats to V4L2
+   pixel formats was accordingly corrected.
+
+2. Unrelated to the fixes above, drivers may still interpret some V4L2
+   RGB pixel formats differently. These issues have yet to be addressed,
+   for details see :ref:`pixfmt-rgb`.
+
+
+V4L2 in Linux 2.6.6, 2004-05-09
+===============================
+
+1. The :ref:`VIDIOC_CROPCAP` ioctl was incorrectly
+   defined with read-only parameter. It is now defined as write-read
+   ioctl, while the read-only version was renamed to
+   ``VIDIOC_CROPCAP_OLD``. The old ioctl was removed on Kernel 2.6.39.
+
+
+V4L2 in Linux 2.6.8
+===================
+
+1. A new field ``input`` (former ``reserved[0]``) was added to the
+   struct :ref:`v4l2_buffer <v4l2-buffer>` structure. Purpose of this
+   field is to alternate between video inputs (e. g. cameras) in step
+   with the video capturing process. This function must be enabled with
+   the new ``V4L2_BUF_FLAG_INPUT`` flag. The ``flags`` field is no
+   longer read-only.
+
+
+V4L2 spec erratum 2004-08-01
+============================
+
+1. The return value of the :ref:`func-open` function was incorrectly
+   documented.
+
+2. Audio output ioctls end in -AUDOUT, not -AUDIOOUT.
+
+3. In the Current Audio Input example the ``VIDIOC_G_AUDIO`` ioctl took
+   the wrong argument.
+
+4. The documentation of the :ref:`VIDIOC_QBUF` and
+   :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctls did not mention the
+   struct :ref:`v4l2_buffer <v4l2-buffer>` ``memory`` field. It was
+   also missing from examples. Also on the ``VIDIOC_DQBUF`` page the ``EIO``
+   error code was not documented.
+
+
+V4L2 in Linux 2.6.14
+====================
+
+1. A new sliced VBI interface was added. It is documented in
+   :ref:`sliced` and replaces the interface first proposed in V4L2
+   specification 0.8.
+
+
+V4L2 in Linux 2.6.15
+====================
+
+1. The :ref:`VIDIOC_LOG_STATUS` ioctl was added.
+
+2. New video standards ``V4L2_STD_NTSC_443``, ``V4L2_STD_SECAM_LC``,
+   ``V4L2_STD_SECAM_DK`` (a set of SECAM D, K and K1), and
+   ``V4L2_STD_ATSC`` (a set of ``V4L2_STD_ATSC_8_VSB`` and
+   ``V4L2_STD_ATSC_16_VSB``) were defined. Note the ``V4L2_STD_525_60``
+   set now includes ``V4L2_STD_NTSC_443``. See also
+   :ref:`v4l2-std-id`.
+
+3. The ``VIDIOC_G_COMP`` and ``VIDIOC_S_COMP`` ioctl were renamed to
+   ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` respectively. Their
+   argument was replaced by a struct
+   :c:type:`struct v4l2_mpeg_compression` pointer. (The
+   ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` ioctls where removed
+   in Linux 2.6.25.)
+
+
+V4L2 spec erratum 2005-11-27
+============================
+
+The capture example in :ref:`capture-example` called the
+:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctl without checking if
+cropping is supported. In the video standard selection example in
+:ref:`standard` the :ref:`VIDIOC_S_STD <VIDIOC_G_STD>` call used
+the wrong argument type.
+
+
+V4L2 spec erratum 2006-01-10
+============================
+
+1. The ``V4L2_IN_ST_COLOR_KILL`` flag in struct
+   :ref:`v4l2_input <v4l2-input>` not only indicates if the color
+   killer is enabled, but also if it is active. (The color killer
+   disables color decoding when it detects no color in the video signal
+   to improve the image quality.)
+
+2. :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` is a write-read ioctl, not
+   write-only as stated on its reference page. The ioctl changed in 2003
+   as noted above.
+
+
+V4L2 spec erratum 2006-02-03
+============================
+
+1. In struct :ref:`v4l2_captureparm <v4l2-captureparm>` and struct
+   :ref:`v4l2_outputparm <v4l2-outputparm>` the ``timeperframe``
+   field gives the time in seconds, not microseconds.
+
+
+V4L2 spec erratum 2006-02-04
+============================
+
+1. The ``clips`` field in struct :ref:`v4l2_window <v4l2-window>`
+   must point to an array of struct :ref:`v4l2_clip <v4l2-clip>`, not
+   a linked list, because drivers ignore the struct
+   :c:type:`struct v4l2_clip`. ``next`` pointer.
+
+
+V4L2 in Linux 2.6.17
+====================
+
+1. New video standard macros were added: ``V4L2_STD_NTSC_M_KR`` (NTSC M
+   South Korea), and the sets ``V4L2_STD_MN``, ``V4L2_STD_B``,
+   ``V4L2_STD_GH`` and ``V4L2_STD_DK``. The ``V4L2_STD_NTSC`` and
+   ``V4L2_STD_SECAM`` sets now include ``V4L2_STD_NTSC_M_KR`` and
+   ``V4L2_STD_SECAM_LC`` respectively.
+
+2. A new ``V4L2_TUNER_MODE_LANG1_LANG2`` was defined to record both
+   languages of a bilingual program. The use of
+   ``V4L2_TUNER_MODE_STEREO`` for this purpose is deprecated now. See
+   the :ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` section for details.
+
+
+V4L2 spec erratum 2006-09-23 (Draft 0.15)
+=========================================
+
+1. In various places ``V4L2_BUF_TYPE_SLICED_VBI_CAPTURE`` and
+   ``V4L2_BUF_TYPE_SLICED_VBI_OUTPUT`` of the sliced VBI interface were
+   not mentioned along with other buffer types.
+
+2. In :ref:`VIDIOC_G_AUDIO <VIDIOC_G_AUDIO>` it was clarified that the struct
+   :ref:`v4l2_audio <v4l2-audio>` ``mode`` field is a flags field.
+
+3. :ref:`VIDIOC_QUERYCAP` did not mention the sliced VBI and radio
+   capability flags.
+
+4. In :ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` it was clarified that applications
+   must initialize the tuner ``type`` field of struct
+   :ref:`v4l2_frequency <v4l2-frequency>` before calling
+   :ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>`.
+
+5. The ``reserved`` array in struct
+   :ref:`v4l2_requestbuffers <v4l2-requestbuffers>` has 2 elements,
+   not 32.
+
+6. In :ref:`output` and :ref:`raw-vbi` the device file names
+   ``/dev/vout`` which never caught on were replaced by ``/dev/video``.
+
+7. With Linux 2.6.15 the possible range for VBI device minor numbers was
+   extended from 224-239 to 224-255. Accordingly device file names
+   ``/dev/vbi0`` to ``/dev/vbi31`` are possible now.
+
+
+V4L2 in Linux 2.6.18
+====================
+
+1. New ioctls :ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`,
+   :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` and
+   :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` were added, a
+   flag to skip unsupported controls with
+   :ref:`VIDIOC_QUERYCTRL`, new control types
+   ``V4L2_CTRL_TYPE_INTEGER64`` and ``V4L2_CTRL_TYPE_CTRL_CLASS``
+   (:ref:`v4l2-ctrl-type`), and new control flags
+   ``V4L2_CTRL_FLAG_READ_ONLY``, ``V4L2_CTRL_FLAG_UPDATE``,
+   ``V4L2_CTRL_FLAG_INACTIVE`` and ``V4L2_CTRL_FLAG_SLIDER``
+   (:ref:`control-flags`). See :ref:`extended-controls` for details.
+
+
+V4L2 in Linux 2.6.19
+====================
+
+1. In struct :ref:`v4l2_sliced_vbi_cap <v4l2-sliced-vbi-cap>` a
+   buffer type field was added replacing a reserved field. Note on
+   architectures where the size of enum types differs from int types the
+   size of the structure changed. The
+   :ref:`VIDIOC_G_SLICED_VBI_CAP <VIDIOC_G_SLICED_VBI_CAP>` ioctl
+   was redefined from being read-only to write-read. Applications must
+   initialize the type field and clear the reserved fields now. These
+   changes may *break the compatibility* with older drivers and
+   applications.
+
+2. The ioctls :ref:`VIDIOC_ENUM_FRAMESIZES`
+   and
+   :ref:`VIDIOC_ENUM_FRAMEINTERVALS`
+   were added.
+
+3. A new pixel format ``V4L2_PIX_FMT_RGB444`` (:ref:`rgb-formats`) was
+   added.
+
+
+V4L2 spec erratum 2006-10-12 (Draft 0.17)
+=========================================
+
+1. ``V4L2_PIX_FMT_HM12`` (:ref:`reserved-formats`) is a YUV 4:2:0, not
+   4:2:2 format.
+
+
+V4L2 in Linux 2.6.21
+====================
+
+1. The ``videodev2.h`` header file is now dual licensed under GNU
+   General Public License version two or later, and under a 3-clause
+   BSD-style license.
+
+
+V4L2 in Linux 2.6.22
+====================
+
+1. Two new field orders ``V4L2_FIELD_INTERLACED_TB`` and
+   ``V4L2_FIELD_INTERLACED_BT`` were added. See :ref:`v4l2-field` for
+   details.
+
+2. Three new clipping/blending methods with a global or straight or
+   inverted local alpha value were added to the video overlay interface.
+   See the description of the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
+   and :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctls for details.
+
+   A new ``global_alpha`` field was added to
+   :ref:`v4l2_window <v4l2-window>`, extending the structure. This
+   may *break compatibility* with applications using a struct
+   :c:type:`struct v4l2_window` directly. However the
+   :ref:`VIDIOC_G/S/TRY_FMT <VIDIOC_G_FMT>` ioctls, which take a
+   pointer to a :ref:`v4l2_format <v4l2-format>` parent structure
+   with padding bytes at the end, are not affected.
+
+3. The format of the ``chromakey`` field in struct
+   :ref:`v4l2_window <v4l2-window>` changed from "host order RGB32"
+   to a pixel value in the same format as the framebuffer. This may
+   *break compatibility* with existing applications. Drivers supporting
+   the "host order RGB32" format are not known.
+
+
+V4L2 in Linux 2.6.24
+====================
+
+1. The pixel formats ``V4L2_PIX_FMT_PAL8``, ``V4L2_PIX_FMT_YUV444``,
+   ``V4L2_PIX_FMT_YUV555``, ``V4L2_PIX_FMT_YUV565`` and
+   ``V4L2_PIX_FMT_YUV32`` were added.
+
+
+V4L2 in Linux 2.6.25
+====================
+
+1. The pixel formats :ref:`V4L2_PIX_FMT_Y16 <V4L2-PIX-FMT-Y16>` and
+   :ref:`V4L2_PIX_FMT_SBGGR16 <V4L2-PIX-FMT-SBGGR16>` were added.
+
+2. New :ref:`controls <control>` ``V4L2_CID_POWER_LINE_FREQUENCY``,
+   ``V4L2_CID_HUE_AUTO``, ``V4L2_CID_WHITE_BALANCE_TEMPERATURE``,
+   ``V4L2_CID_SHARPNESS`` and ``V4L2_CID_BACKLIGHT_COMPENSATION`` were
+   added. The controls ``V4L2_CID_BLACK_LEVEL``, ``V4L2_CID_WHITENESS``,
+   ``V4L2_CID_HCENTER`` and ``V4L2_CID_VCENTER`` were deprecated.
+
+3. A :ref:`Camera controls class <camera-controls>` was added, with
+   the new controls ``V4L2_CID_EXPOSURE_AUTO``,
+   ``V4L2_CID_EXPOSURE_ABSOLUTE``, ``V4L2_CID_EXPOSURE_AUTO_PRIORITY``,
+   ``V4L2_CID_PAN_RELATIVE``, ``V4L2_CID_TILT_RELATIVE``,
+   ``V4L2_CID_PAN_RESET``, ``V4L2_CID_TILT_RESET``,
+   ``V4L2_CID_PAN_ABSOLUTE``, ``V4L2_CID_TILT_ABSOLUTE``,
+   ``V4L2_CID_FOCUS_ABSOLUTE``, ``V4L2_CID_FOCUS_RELATIVE`` and
+   ``V4L2_CID_FOCUS_AUTO``.
+
+4. The ``VIDIOC_G_MPEGCOMP`` and ``VIDIOC_S_MPEGCOMP`` ioctls, which
+   were superseded by the :ref:`extended controls <extended-controls>`
+   interface in Linux 2.6.18, where finally removed from the
+   ``videodev2.h`` header file.
+
+
+V4L2 in Linux 2.6.26
+====================
+
+1. The pixel formats ``V4L2_PIX_FMT_Y16`` and ``V4L2_PIX_FMT_SBGGR16``
+   were added.
+
+2. Added user controls ``V4L2_CID_CHROMA_AGC`` and
+   ``V4L2_CID_COLOR_KILLER``.
+
+
+V4L2 in Linux 2.6.27
+====================
+
+1. The :ref:`VIDIOC_S_HW_FREQ_SEEK` ioctl
+   and the ``V4L2_CAP_HW_FREQ_SEEK`` capability were added.
+
+2. The pixel formats ``V4L2_PIX_FMT_YVYU``, ``V4L2_PIX_FMT_PCA501``,
+   ``V4L2_PIX_FMT_PCA505``, ``V4L2_PIX_FMT_PCA508``,
+   ``V4L2_PIX_FMT_PCA561``, ``V4L2_PIX_FMT_SGBRG8``,
+   ``V4L2_PIX_FMT_PAC207`` and ``V4L2_PIX_FMT_PJPG`` were added.
+
+
+V4L2 in Linux 2.6.28
+====================
+
+1. Added ``V4L2_MPEG_AUDIO_ENCODING_AAC`` and
+   ``V4L2_MPEG_AUDIO_ENCODING_AC3`` MPEG audio encodings.
+
+2. Added ``V4L2_MPEG_VIDEO_ENCODING_MPEG_4_AVC`` MPEG video encoding.
+
+3. The pixel formats ``V4L2_PIX_FMT_SGRBG10`` and
+   ``V4L2_PIX_FMT_SGRBG10DPCM8`` were added.
+
+
+V4L2 in Linux 2.6.29
+====================
+
+1. The ``VIDIOC_G_CHIP_IDENT`` ioctl was renamed to
+   ``VIDIOC_G_CHIP_IDENT_OLD`` and ``VIDIOC_DBG_G_CHIP_IDENT`` was
+   introduced in its place. The old struct
+   :c:type:`struct v4l2_chip_ident` was renamed to
+   :c:type:`struct v4l2_chip_ident_old`.
+
+2. The pixel formats ``V4L2_PIX_FMT_VYUY``, ``V4L2_PIX_FMT_NV16`` and
+   ``V4L2_PIX_FMT_NV61`` were added.
+
+3. Added camera controls ``V4L2_CID_ZOOM_ABSOLUTE``,

+
+V4L2 in Linux 2.6.30
+====================
+
+1. New control flag ``V4L2_CTRL_FLAG_WRITE_ONLY`` was added.
+
+2. New control ``V4L2_CID_COLORFX`` was added.
+
+
+V4L2 in Linux 2.6.32
+====================
+
+1. In order to be easier to compare a V4L2 API and a kernel version, now
+   V4L2 API is numbered using the Linux Kernel version numeration.
+
+2. Finalized the RDS capture API. See :ref:`rds` for more information.
+
+3. Added new capabilities for modulators and RDS encoders.
+
+4. Add description for libv4l API.
+
+5. Added support for string controls via new type
+   ``V4L2_CTRL_TYPE_STRING``.
+
+6. Added ``V4L2_CID_BAND_STOP_FILTER`` documentation.
+
+7. Added FM Modulator (FM TX) Extended Control Class:
+   ``V4L2_CTRL_CLASS_FM_TX`` and their Control IDs.
+
+8. Added FM Receiver (FM RX) Extended Control Class:
+   ``V4L2_CTRL_CLASS_FM_RX`` and their Control IDs.
+
+9. Added Remote Controller chapter, describing the default Remote
+   Controller mapping for media devices.
+
+
+V4L2 in Linux 2.6.33
+====================
+
+1. Added support for Digital Video timings in order to support HDTV
+   receivers and transmitters.
+
+
+V4L2 in Linux 2.6.34
+====================
+
+1. Added ``V4L2_CID_IRIS_ABSOLUTE`` and ``V4L2_CID_IRIS_RELATIVE``
+   controls to the :ref:`Camera controls class <camera-controls>`.
+
+
+V4L2 in Linux 2.6.37
+====================
+
+1. Remove the vtx (videotext/teletext) API. This API was no longer used
+   and no hardware exists to verify the API. Nor were any userspace
+   applications found that used it. It was originally scheduled for
+   removal in 2.6.35.
+
+
+V4L2 in Linux 2.6.39
+====================
+
+1. The old VIDIOC_*_OLD symbols and V4L1 support were removed.
+
+2. Multi-planar API added. Does not affect the compatibility of current
+   drivers and applications. See :ref:`multi-planar API <planar-apis>`
+   for details.

+
+.. _other:
+
+Relation of V4L2 to other Linux multimedia APIs
+===============================================
+
+
+.. _xvideo:
+
+X Video Extension
+-----------------
+
+The X Video Extension (abbreviated XVideo or just Xv) is an extension of
+the X Window system, implemented for example by the XFree86 project. Its
+scope is similar to V4L2, an API to video capture and output devices for
+X clients. Xv allows applications to display live video in a window,
+send window contents to a TV output, and capture or output still images
+in XPixmaps [#f1]_. With their implementation XFree86 makes the extension
+available across many operating systems and architectures.
+
+Because the driver is embedded into the X server Xv has a number of
+advantages over the V4L2 :ref:`video overlay interface <overlay>`. The
+driver can easily determine the overlay target, i. e. visible graphics
+memory or off-screen buffers for a destructive overlay. It can program
+the RAMDAC for a non-destructive overlay, scaling or color-keying, or
+the clipping functions of the video capture hardware, always in sync
+with drawing operations or windows moving or changing their stacking
+order.
+
+To combine the advantages of Xv and V4L a special Xv driver exists in
+XFree86 and XOrg, just programming any overlay capable Video4Linux
+device it finds. To enable it ``/etc/X11/XF86Config`` must contain these
+lines:
+
+::
+
+    Section "Module"
+	Load "v4l"
+    EndSection
+
+As of XFree86 4.2 this driver still supports only V4L ioctls, however it
+should work just fine with all V4L2 devices through the V4L2
+backward-compatibility layer. Since V4L2 permits multiple opens it is
+possible (if supported by the V4L2 driver) to capture video while an X
+client requested video overlay. Restrictions of simultaneous capturing
+and overlay are discussed in :ref:`overlay` apply.
+
+Only marginally related to V4L2, XFree86 extended Xv to support hardware
+YUV to RGB conversion and scaling for faster video playback, and added
+an interface to MPEG-2 decoding hardware. This API is useful to display
+images captured with V4L2 devices.
+
+
+Digital Video
+-------------
+
+V4L2 does not support digital terrestrial, cable or satellite broadcast.
+A separate project aiming at digital receivers exists. You can find its
+homepage at `https://linuxtv.org <https://linuxtv.org>`__. The Linux
+DVB API has no connection to the V4L2 API except that drivers for hybrid
+hardware may support both.

+Input/Output
+############
+The V4L2 API defines several different methods to read from or write to
+a device. All drivers exchanging data with applications must support at
+least one of them.
+
+The classic I/O method using the :ref:`read() <func-read>` and
+:ref:`write() <func-write>` function is automatically selected after opening a
+V4L2 device. When the driver does not support this method attempts to
+read or write will fail at any time.
+
+Other methods must be negotiated. To select the streaming I/O method
+with memory mapped or user buffers applications call the
+:ref:`VIDIOC_REQBUFS` ioctl. The asynchronous I/O
+method is not defined yet.
+
+Video overlay can be considered another I/O method, although the
+application does not directly receive the image data. It is selected by
+initiating video overlay with the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl. For more information see :ref:`overlay`.
+
+Generally exactly one I/O method, including overlay, is associated with
+each file descriptor. The only exceptions are applications not
+exchanging data with a driver ("panel applications", see :ref:`open`)
+and drivers permitting simultaneous video capturing and overlay using
+the same file descriptor, for compatibility with V4L and earlier
+versions of V4L2.
+
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_REQBUFS` would permit this to some
+degree, but for simplicity drivers need not support switching the I/O
+method (after first switching away from read/write) other than by
+closing and reopening the device.

+Introduction
+************
+
+libv4l is a collection of libraries which adds a thin abstraction layer
+on top of video4linux2 devices. The purpose of this (thin) layer is to
+make it easy for application writers to support a wide variety of
+devices without having to write separate code for different devices in
+the same class.
+
+An example of using libv4l is provided by
+:ref:`v4l2grab <v4l2grab-example>`.
+
+libv4l consists of 3 different libraries:
+
+
+libv4lconvert
+=============
+
+libv4lconvert is a library that converts several different pixelformats
+found in V4L2 drivers into a few common RGB and YUY formats.
+
+It currently accepts the following V4L2 driver formats:
+:ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR24>`,
+:ref:`V4L2_PIX_FMT_HM12 <V4L2-PIX-FMT-HM12>`,
+:ref:`V4L2_PIX_FMT_JPEG <V4L2-PIX-FMT-JPEG>`,
+:ref:`V4L2_PIX_FMT_MJPEG <V4L2-PIX-FMT-MJPEG>`,
+:ref:`V4L2_PIX_FMT_MR97310A <V4L2-PIX-FMT-MR97310A>`,
+:ref:`V4L2_PIX_FMT_OV511 <V4L2-PIX-FMT-OV511>`,
+:ref:`V4L2_PIX_FMT_OV518 <V4L2-PIX-FMT-OV518>`,
+:ref:`V4L2_PIX_FMT_PAC207 <V4L2-PIX-FMT-PAC207>`,
+:ref:`V4L2_PIX_FMT_PJPG <V4L2-PIX-FMT-PJPG>`,
+:ref:`V4L2_PIX_FMT_RGB24 <V4L2-PIX-FMT-RGB24>`,
+:ref:`V4L2_PIX_FMT_SBGGR8 <V4L2-PIX-FMT-SBGGR8>`,
+:ref:`V4L2_PIX_FMT_SGBRG8 <V4L2-PIX-FMT-SGBRG8>`,
+:ref:`V4L2_PIX_FMT_SGRBG8 <V4L2-PIX-FMT-SGRBG8>`,
+:ref:`V4L2_PIX_FMT_SN9C10X <V4L2-PIX-FMT-SN9C10X>`,
+:ref:`V4L2_PIX_FMT_SN9C20X_I420 <V4L2-PIX-FMT-SN9C20X-I420>`,
+:ref:`V4L2_PIX_FMT_SPCA501 <V4L2-PIX-FMT-SPCA501>`,
+:ref:`V4L2_PIX_FMT_SPCA505 <V4L2-PIX-FMT-SPCA505>`,
+:ref:`V4L2_PIX_FMT_SPCA508 <V4L2-PIX-FMT-SPCA508>`,
+:ref:`V4L2_PIX_FMT_SPCA561 <V4L2-PIX-FMT-SPCA561>`,
+:ref:`V4L2_PIX_FMT_SQ905C <V4L2-PIX-FMT-SQ905C>`,
+:ref:`V4L2_PIX_FMT_SRGGB8 <V4L2-PIX-FMT-SRGGB8>`,
+:ref:`V4L2_PIX_FMT_UYVY <V4L2-PIX-FMT-UYVY>`,
+:ref:`V4L2_PIX_FMT_YUV420 <V4L2-PIX-FMT-YUV420>`,
+:ref:`V4L2_PIX_FMT_YUYV <V4L2-PIX-FMT-YUYV>`,
+:ref:`V4L2_PIX_FMT_YVU420 <V4L2-PIX-FMT-YVU420>`, and
+:ref:`V4L2_PIX_FMT_YVYU <V4L2-PIX-FMT-YVYU>`.
+
+Later on libv4lconvert was expanded to also be able to do various video
+processing functions to improve webcam video quality. The video
+processing is split in to 2 parts: libv4lconvert/control and
+libv4lconvert/processing.
+
+The control part is used to offer video controls which can be used to
+control the video processing functions made available by
+libv4lconvert/processing. These controls are stored application wide
+(until reboot) by using a persistent shared memory object.
+
+libv4lconvert/processing offers the actual video processing
+functionality.
+
+
+libv4l1
+=======
+
+This library offers functions that can be used to quickly make v4l1
+applications work with v4l2 devices. These functions work exactly like
+the normal open/close/etc, except that libv4l1 does full emulation of
+the v4l1 api on top of v4l2 drivers, in case of v4l1 drivers it will
+just pass calls through.
+
+Since those functions are emulations of the old V4L1 API, it shouldn't
+be used for new applications.
+
+
+libv4l2
+=======
+
+This library should be used for all modern V4L2 applications.
+
+It provides handles to call V4L2 open/ioctl/close/poll methods. Instead
+of just providing the raw output of the device, it enhances the calls in
+the sense that it will use libv4lconvert to provide more video formats
+and to enhance the image quality.
+
+In most cases, libv4l2 just passes the calls directly through to the
+v4l2 driver, intercepting the calls to
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`,
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`,
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`,
+:ref:`VIDIOC_ENUM_FRAMESIZES <VIDIOC_ENUM_FRAMESIZES>` and
+:ref:`VIDIOC_ENUM_FRAMEINTERVALS <VIDIOC_ENUM_FRAMEINTERVALS>` in
+order to emulate the formats
+:ref:`V4L2_PIX_FMT_BGR24 <V4L2-PIX-FMT-BGR24>`,
+:ref:`V4L2_PIX_FMT_RGB24 <V4L2-PIX-FMT-RGB24>`,
+:ref:`V4L2_PIX_FMT_YUV420 <V4L2-PIX-FMT-YUV420>`, and
+:ref:`V4L2_PIX_FMT_YVU420 <V4L2-PIX-FMT-YVU420>`, if they aren't
+available in the driver. :ref:`VIDIOC_ENUM_FMT <VIDIOC_ENUM_FMT>`
+keeps enumerating the hardware supported formats, plus the emulated
+formats offered by libv4l at the end.
+
+
+.. _libv4l-ops:
+
+Libv4l device control functions
+-------------------------------
+
+The common file operation methods are provided by libv4l.
+
+Those functions operate just like glibc
+open/close/dup/ioctl/read/mmap/munmap:
+
+-  :c:type:`int v4l2_open(const char *file, int oflag, ...)` - operates like the
+   standard :ref:`open() <func-open>` function.
+
+-  :c:type:`int v4l2_close(int fd)` - operates like the standard
+   :ref:`close() <func-close>` function.
+
+-  :c:type:`int v4l2_dup(int fd)` - operates like the standard dup() function,
+   duplicating a file handler.
+
+-  :c:type:`int v4l2_ioctl (int fd, unsigned long int request, ...)` - operates
+   like the standard :ref:`ioctl() <func-ioctl>` function.
+
+-  :c:type:`int v4l2_read (int fd, void* buffer, size_t n)` - operates like the
+   standard :ref:`read() <func-read>` function.
+
+-  :c:type:`void v4l2_mmap(void *start, size_t length, int prot, int flags, int
+   fd, int64_t offset);` - operates like the standard
+   :ref:`mmap() <func-mmap>` function.
+
+-  :c:type:`int v4l2_munmap(void *_start, size_t length);` - operates like the
+   standard :ref:`munmap() <func-munmap>` function.
+
+Those functions provide additional control:
+
+-  :c:type:`int v4l2_fd_open(int fd, int v4l2_flags)` - opens an already opened
+   fd for further use through v4l2lib and possibly modify libv4l2's
+   default behavior through the v4l2_flags argument. Currently,
+   v4l2_flags can be ``V4L2_DISABLE_CONVERSION``, to disable format
+   conversion.
+
+-  :c:type:`int v4l2_set_control(int fd, int cid, int value)` - This function
+   takes a value of 0 - 65535, and then scales that range to the actual
+   range of the given v4l control id, and then if the cid exists and is
+   not locked sets the cid to the scaled value.
+
+-  :c:type:`int v4l2_get_control(int fd, int cid)` - This function returns a
+   value of 0 - 65535, scaled to from the actual range of the given v4l
+   control id. when the cid does not exist, could not be accessed for
+   some reason, or some error occurred 0 is returned.
+
+
+v4l1compat.so wrapper library
+=============================
+
+This library intercepts calls to open/close/ioctl/mmap/mmunmap
+operations and redirects them to the libv4l counterparts, by using
+LD_PRELOAD=/usr/lib/v4l1compat.so. It also emulates V4L1 calls via V4L2
+API.
+
+It allows usage of binary legacy applications that still don't use
+libv4l.

+******************************
+Streaming I/O (Memory Mapping)
+******************************
+
+Input and output devices support this I/O method when the
+``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl is set. There are two
+streaming methods, to determine if the memory mapping flavor is
+supported applications must call the :ref:`VIDIOC_REQBUFS` ioctl
+with the memory type set to ``V4L2_MEMORY_MMAP``.
+
+Streaming is an I/O method where only pointers to buffers are exchanged
+between application and driver, the data itself is not copied. Memory
+mapping is primarily intended to map buffers in device memory into the
+application's address space. Device memory can be for example the video
+memory on a graphics card with a video capture add-on. However, being
+the most efficient I/O method available for a long time, many other
+drivers support streaming as well, allocating buffers in DMA-able main
+memory.
+
+A driver can support many sets of buffers. Each set is identified by a
+unique buffer type value. The sets are independent and each set can hold
+a different type of data. To access different sets at the same time
+different file descriptors must be used. [#f1]_
+
+To allocate device buffers applications call the
+:ref:`VIDIOC_REQBUFS` ioctl with the desired number
+of buffers and buffer type, for example ``V4L2_BUF_TYPE_VIDEO_CAPTURE``.
+This ioctl can also be used to change the number of buffers or to free
+the allocated memory, provided none of the buffers are still mapped.
+
+Before applications can access the buffers they must map them into their
+address space with the :ref:`mmap() <func-mmap>` function. The
+location of the buffers in device memory can be determined with the
+:ref:`VIDIOC_QUERYBUF` ioctl. In the single-planar
+API case, the ``m.offset`` and ``length`` returned in a struct
+:ref:`v4l2_buffer <v4l2-buffer>` are passed as sixth and second
+parameter to the :ref:`mmap() <func-mmap>` function. When using the
+multi-planar API, struct :ref:`v4l2_buffer <v4l2-buffer>` contains an
+array of struct :ref:`v4l2_plane <v4l2-plane>` structures, each
+containing its own ``m.offset`` and ``length``. When using the
+multi-planar API, every plane of every buffer has to be mapped
+separately, so the number of calls to :ref:`mmap() <func-mmap>` should
+be equal to number of buffers times number of planes in each buffer. The
+offset and length values must not be modified. Remember, the buffers are
+allocated in physical memory, as opposed to virtual memory, which can be
+swapped out to disk. Applications should free the buffers as soon as
+possible with the :ref:`munmap() <func-munmap>` function.

+
+Conceptually streaming drivers maintain two buffer queues, an incoming
+and an outgoing queue. They separate the synchronous capture or output
+operation locked to a video clock from the application which is subject
+to random disk or network delays and preemption by other processes,
+thereby reducing the probability of data loss. The queues are organized
+as FIFOs, buffers will be output in the order enqueued in the incoming
+FIFO, and were captured in the order dequeued from the outgoing FIFO.
+
+The driver may require a minimum number of buffers enqueued at all times
+to function, apart of this no limit exists on the number of buffers
+applications can enqueue in advance, or dequeue and process. They can
+also enqueue in a different order than buffers have been dequeued, and
+the driver can *fill* enqueued *empty* buffers in any order.  [#f2]_ The
+index number of a buffer (struct :ref:`v4l2_buffer <v4l2-buffer>`
+``index``) plays no role here, it only identifies the buffer.
+
+Initially all mapped buffers are in dequeued state, inaccessible by the
+driver. For capturing applications it is customary to first enqueue all
+mapped buffers, then to start capturing and enter the read loop. Here
+the application waits until a filled buffer can be dequeued, and
+re-enqueues the buffer when the data is no longer needed. Output
+applications fill and enqueue buffers, when enough buffers are stacked
+up the output is started with :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`.
+In the write loop, when the application runs out of free buffers, it
+must wait until an empty buffer can be dequeued and reused.
+
+To enqueue and dequeue a buffer applications use the :ref:`VIDIOC_QBUF`
+and :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. The status of a buffer
+being mapped, enqueued, full or empty can be determined at any time
+using the :ref:`VIDIOC_QUERYBUF` ioctl. Two methods exist to suspend
+execution of the application until one or more buffers can be dequeued.
+By default :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` blocks when no buffer is
+in the outgoing queue. When the ``O_NONBLOCK`` flag was given to the
+:ref:`open() <func-open>` function, :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`
+returns immediately with an ``EAGAIN`` error code when no buffer is
+available. The :ref:`select() <func-select>` or :ref:`poll()
+<func-poll>` functions are always available.
+
+To start and stop capturing or output applications call the
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and :ref:`VIDIOC_STREAMOFF
+<VIDIOC_STREAMON>` ioctl.
+
+.. note:::ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
+   removes all buffers from both queues as a side effect. Since there is
+   no notion of doing anything "now" on a multitasking system, if an
+   application needs to synchronize with another event it should examine
+   the struct ::ref:`v4l2_buffer <v4l2-buffer>` ``timestamp`` of captured
+   or outputted buffers.
+
+Drivers implementing memory mapping I/O must support the
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QUERYBUF
+<VIDIOC_QUERYBUF>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_DQBUF
+<VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
+and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls, the :ref:`mmap()
+<func-mmap>`, :ref:`munmap() <func-munmap>`, :ref:`select()
+<func-select>` and :ref:`poll() <func-poll>` function. [#f3]_
+
+[capture example]
+
+.. [#f1]
+   One could use one file descriptor and set the buffer type field
+   accordingly when calling :ref:`VIDIOC_QBUF` etc.,
+   but it makes the :ref:`select() <func-select>` function ambiguous. We also
+   like the clean approach of one file descriptor per logical stream.
+   Video overlay for example is also a logical stream, although the CPU
+   is not needed for continuous operation.
+
+.. [#f2]
+   Random enqueue order permits applications processing images out of
+   order (such as video codecs) to return buffers earlier, reducing the
+   probability of data loss. Random fill order allows drivers to reuse
+   buffers on a LIFO-basis, taking advantage of caches holding
+   scatter-gather lists and the like.
+
+.. [#f3]
+   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
+   the same, and :ref:`select() <func-select>` is too important to be optional.
+   The rest should be evident.

+***************************
+Opening and Closing Devices
+***************************
+
+
+Device Naming
+=============
+
+V4L2 drivers are implemented as kernel modules, loaded manually by the
+system administrator or automatically when a device is first discovered.
+The driver modules plug into the "videodev" kernel module. It provides
+helper functions and a common application interface specified in this
+document.
+
+Each driver thus loaded registers one or more device nodes with major
+number 81 and a minor number between 0 and 255. Minor numbers are
+allocated dynamically unless the kernel is compiled with the kernel
+option CONFIG_VIDEO_FIXED_MINOR_RANGES. In that case minor numbers
+are allocated in ranges depending on the device node type (video, radio,
+etc.).
+
+Many drivers support "video_nr", "radio_nr" or "vbi_nr" module
+options to select specific video/radio/vbi node numbers. This allows the
+user to request that the device node is named e.g. /dev/video5 instead
+of leaving it to chance. When the driver supports multiple devices of
+the same type more than one device node number can be assigned,
+separated by commas:
+
+.. code-block:: none
+
+   # modprobe mydriver video_nr=0,1 radio_nr=0,1
+
+In ``/etc/modules.conf`` this may be written as:
+
+::
+
+    options mydriver video_nr=0,1 radio_nr=0,1
+
+When no device node number is given as module option the driver supplies
+a default.
+
+Normally udev will create the device nodes in /dev automatically for
+you. If udev is not installed, then you need to enable the
+CONFIG_VIDEO_FIXED_MINOR_RANGES kernel option in order to be able to
+correctly relate a minor number to a device node number. I.e., you need
+to be certain that minor number 5 maps to device node name video5. With
+this kernel option different device types have different minor number
+ranges. These ranges are listed in :ref:`devices`.
+
+The creation of character special files (with mknod) is a privileged
+operation and devices cannot be opened by major and minor number. That
+means applications cannot *reliable* scan for loaded or installed
+drivers. The user must enter a device name, or the application can try
+the conventional device names.
+
+
+.. _related:
+
+Related Devices
+===============
+
+Devices can support several functions. For example video capturing, VBI
+capturing and radio support.
+
+The V4L2 API creates different nodes for each of these functions.
+
+The V4L2 API was designed with the idea that one device node could
+support all functions. However, in practice this never worked: this
+'feature' was never used by applications and many drivers did not
+support it and if they did it was certainly never tested. In addition,
+switching a device node between different functions only works when
+using the streaming I/O API, not with the
+:ref:`read() <func-read>`/\ :ref:`write() <func-write>` API.
+
+Today each device node supports just one function.
+
+Besides video input or output the hardware may also support audio
+sampling or playback. If so, these functions are implemented as ALSA PCM
+devices with optional ALSA audio mixer devices.
+
+One problem with all these devices is that the V4L2 API makes no
+provisions to find these related devices. Some really complex devices
+use the Media Controller (see :ref:`media_controller`) which can be
+used for this purpose. But most drivers do not use it, and while some
+code exists that uses sysfs to discover related devices (see
+libmedia_dev in the
+`v4l-utils <http://git.linuxtv.org/cgit.cgi/v4l-utils.git/>`__ git
+repository), there is no library yet that can provide a single API
+towards both Media Controller-based devices and devices that do not use
+the Media Controller. If you want to work on this please write to the
+linux-media mailing list:
+`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__.
+
+
+Multiple Opens
+==============
+
+V4L2 devices can be opened more than once. [#f1]_ When this is supported
+by the driver, users can for example start a "panel" application to
+change controls like brightness or audio volume, while another
+application captures video and audio. In other words, panel applications
+are comparable to an ALSA audio mixer application. Just opening a V4L2
+device should not change the state of the device. [#f2]_
+
+Once an application has allocated the memory buffers needed for
+streaming data (by calling the :ref:`VIDIOC_REQBUFS`
+or :ref:`VIDIOC_CREATE_BUFS` ioctls, or
+implicitly by calling the :ref:`read() <func-read>` or
+:ref:`write() <func-write>` functions) that application (filehandle)
+becomes the owner of the device. It is no longer allowed to make changes
+that would affect the buffer sizes (e.g. by calling the
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl) and other applications are
+no longer allowed to allocate buffers or start or stop streaming. The
+EBUSY error code will be returned instead.
+
+Merely opening a V4L2 device does not grant exclusive access. [#f3]_
+Initiating data exchange however assigns the right to read or write the
+requested type of data, and to change related properties, to this file
+descriptor. Applications can request additional access privileges using
+the priority mechanism described in :ref:`app-pri`.
+
+
+Shared Data Streams
+===================
+
+V4L2 drivers should not support multiple applications reading or writing
+the same data stream on a device by copying buffers, time multiplexing
+or similar means. This is better handled by a proxy application in user
+space.
+
+
+Functions
+=========
+
+To open and close V4L2 devices applications use the
+:ref:`open() <func-open>` and :ref:`close() <func-close>` function,
+respectively. Devices are programmed using the
+:ref:`ioctl() <func-ioctl>` function as explained in the following
+sections.
+
+.. [#f1]
+   There are still some old and obscure drivers that have not been
+   updated to allow for multiple opens. This implies that for such
+   drivers :ref:`open() <func-open>` can return an ``EBUSY`` error code
+   when the device is already in use.
+
+.. [#f2]
+   Unfortunately, opening a radio device often switches the state of the
+   device to radio mode in many drivers. This behavior should be fixed
+   eventually as it violates the V4L2 specification.
+
+.. [#f3]
+   Drivers could recognize the ``O_EXCL`` open flag. Presently this is
+   not required, so applications cannot know if it really works.

+
+	  Both applications and drivers can set this field to request
+	  padding bytes at the end of each line. Drivers however may ignore
+	  the value requested by the application, returning ``width`` times

+
+	  Video hardware may access padding bytes, therefore they must

+	  after the last line of an image cross a system page boundary.
+	  Input devices may write padding bytes, the value is undefined.
+	  Output devices ignore the contents of padding bytes.
+
+	  When the image format is planar the ``bytesperline`` value applies
+	  to the first plane and is divided by the same factor as the
+	  ``width`` field for the other planes. For example the Cb and Cr
+	  planes of a YUV 4:2:0 image have half as many padding bytes
+	  following each line as the Y plane. To avoid ambiguities drivers
+	  must return a ``bytesperline`` value rounded up to a multiple of
+	  the scale factor.
+
+	  For compressed formats the ``bytesperline`` value makes no sense.

+	  have been correctly initialized. When set to any other value it
+	  indicates that the extended fields contain undefined values.
+
+	  Applications that wish to use the pixel format extended fields
+	  must first ensure that the feature is supported by querying the

+
+	  When the ``priv`` field isn't set to ``V4L2_PIX_FMT_PRIV_MAGIC``

+**********************
+Standard Image Formats
+**********************
+
+In order to exchange images between drivers and applications, it is
+necessary to have standard image data formats which both sides will
+interpret the same way. V4L2 includes several such formats, and this
+section is intended to be an unambiguous specification of the standard
+image data formats in V4L2.
+
+V4L2 drivers are not limited to these formats, however. Driver-specific
+formats are possible. In that case the application may depend on a codec
+to convert images to one of the standard formats when needed. But the
+data can still be stored and retrieved in the proprietary format. For
+example, a device may support a proprietary compressed format.
+Applications can still capture and save the data in the compressed
+format, saving much disk space, and later use a codec to convert the
+images to the X Windows screen format when the video is to be displayed.
+
+Even so, ultimately, some standard formats are needed, so the V4L2
+specification would not be complete without well-defined standard
+formats.
+
+The V4L2 standard formats are mainly uncompressed formats. The pixels
+are always arranged in memory from left to right, and from top to
+bottom. The first byte of data in the image buffer is always for the
+leftmost pixel of the topmost row. Following that is the pixel
+immediately to its right, and so on until the end of the top row of
+pixels. Following the rightmost pixel of the row there may be zero or
+more bytes of padding to guarantee that each row of pixel data has a
+certain alignment. Following the pad bytes, if any, is data for the
+leftmost pixel of the second row from the top, and so on. The last row
+has just as many pad bytes after it as the other rows.
+
+In V4L2 each format has an identifier which looks like ``PIX_FMT_XXX``,
+defined in the :ref:`videodev2.h <videodev>` header file. These
+identifiers represent
+:ref:`four character (FourCC) codes <v4l2-fourcc>` which are also
+listed below, however they are not the same as those used in the Windows
+world.
+
+For some formats, data is stored in separate, discontiguous memory
+buffers. Those formats are identified by a separate set of FourCC codes
+and are referred to as "multi-planar formats". For example, a
+:ref:`YUV422 <V4L2-PIX-FMT-YUV422M>` frame is normally stored in one
+memory buffer, but it can also be placed in two or three separate
+buffers, with Y component in one buffer and CbCr components in another
+in the 2-planar version or with each component in its own buffer in the
+3-planar case. Those sub-buffers are referred to as "*planes*".

+****************************
+Defining Colorspaces in V4L2
+****************************
+
+In V4L2 colorspaces are defined by four values. The first is the
+colorspace identifier (enum :ref:`v4l2_colorspace <v4l2-colorspace>`)
+which defines the chromaticities, the default transfer function, the
+default Y'CbCr encoding and the default quantization method. The second
+is the transfer function identifier (enum
+:ref:`v4l2_xfer_func <v4l2-xfer-func>`) to specify non-standard
+transfer functions. The third is the Y'CbCr encoding identifier (enum
+:ref:`v4l2_ycbcr_encoding <v4l2-ycbcr-encoding>`) to specify
+non-standard Y'CbCr encodings and the fourth is the quantization
+identifier (enum :ref:`v4l2_quantization <v4l2-quantization>`) to
+specify non-standard quantization methods. Most of the time only the
+colorspace field of struct :ref:`v4l2_pix_format <v4l2-pix-format>`
+or struct :ref:`v4l2_pix_format_mplane <v4l2-pix-format-mplane>`
+needs to be filled in.
+
+.. note:: The default R'G'B' quantization is full range for all
+   colorspaces except for BT.2020 which uses limited range R'G'B'
+   quantization.

+
+The red, green and blue chromaticities are also often referred to as the

+
+The default quantization is limited range, but full range is possible

+
+The ``V4L2_YCBCR_ENC_709`` encoding described above is the default for
+this colorspace, but it can be overridden with ``V4L2_YCBCR_ENC_601``,
+in which case the BT.601 Y'CbCr encoding is used.
+
+Two additional extended gamut Y'CbCr encodings are also possible with
+this colorspace:
+
+The xvYCC 709 encoding (``V4L2_YCBCR_ENC_XV709``, :ref:`xvycc`) is
+similar to the Rec. 709 encoding, but it allows for R', G' and B' values
+that are outside the range [0…1]. The resulting Y', Cb and Cr values are
+scaled and offset:
+
+    Y' = (219 / 256) * (0.2126R' + 0.7152G' + 0.0722B') + (16 / 256)
+
+    Cb = (224 / 256) * (-0.1146R' - 0.3854G' + 0.5B')
+
+    Cr = (224 / 256) * (0.5R' - 0.4542G' - 0.0458B')
+
+The xvYCC 601 encoding (``V4L2_YCBCR_ENC_XV601``, :ref:`xvycc`) is
+similar to the BT.601 encoding, but it allows for R', G' and B' values
+that are outside the range [0…1]. The resulting Y', Cb and Cr values are
+scaled and offset:
+
+    Y' = (219 / 256) * (0.299R' + 0.587G' + 0.114B') + (16 / 256)
+
+    Cb = (224 / 256) * (-0.169R' - 0.331G' + 0.5B')
+
+    Cr = (224 / 256) * (0.5R' - 0.419G' - 0.081B')
+
+Y' is clamped to the range [0…1] and Cb and Cr are clamped to the range
+[-0.5…0.5]. The non-standard xvYCC 709 or xvYCC 601 encodings can be
+used by selecting ``V4L2_YCBCR_ENC_XV709`` or ``V4L2_YCBCR_ENC_XV601``.
+The xvYCC encodings always use full range quantization.

+Format with ½ horizontal and vertical chroma resolution, also known as
+YUV 4:2:0. Hybrid plane line-interleaved layout.
+
+
+Description
+===========
+
+M420 is a YUV format with ½ horizontal and vertical chroma subsampling
+(YUV 4:2:0). Pixels are organized as interleaved luma and chroma planes.
+Two lines of luma data are followed by one line of chroma data.
+
+The luma plane has one byte per pixel. The chroma plane contains
+interleaved CbCr pixels subsampled by ½ in the horizontal and vertical
+directions. Each CbCr pair belongs to four pixels. For example,
+Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`,
+Y'\ :sub:`10`, Y'\ :sub:`11`.
+
+All line lengths are identical: if the Y lines include pad bytes so do
+the CbCr lines.
+
+**Byte Order.**
+Each cell is one byte.

+V4L2_PIX_FMT_NV21
+Formats with ½ horizontal and vertical chroma resolution, also known as
+YUV 4:2:0. One luminance and one chrominance plane with alternating
+chroma samples as opposed to ``V4L2_PIX_FMT_YVU420``
+
+
+Description
+===========
+
+These are two-plane versions of the YUV 4:2:0 format. The three
+components are separated into two sub-images or planes. The Y plane is
+first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_NV12``, a
+combined CbCr plane immediately follows the Y plane in memory. The CbCr
+plane is the same width, in bytes, as the Y plane (and of the image),
+but is half as tall in pixels. Each CbCr pair belongs to four pixels.
+For example, Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`,
+Y'\ :sub:`01`, Y'\ :sub:`10`, Y'\ :sub:`11`. ``V4L2_PIX_FMT_NV21`` is
+the same except the Cb and Cr bytes are swapped, the CrCb plane starts
+with a Cr byte.
+
+If the Y plane has pad bytes after each row, then the CbCr plane has as
+many pad bytes after its rows.
+
+**Byte Order.**
+Each cell is one byte.

+V4L2_PIX_FMT_NV12MT_16X16
+Variation of ``V4L2_PIX_FMT_NV12`` and ``V4L2_PIX_FMT_NV21`` with planes
+non contiguous in memory.
+
+
+Description
+===========
+
+This is a multi-planar, two-plane version of the YUV 4:2:0 format. The
+three components are separated into two sub-images or planes.
+``V4L2_PIX_FMT_NV12M`` differs from ``V4L2_PIX_FMT_NV12`` in that the
+two planes are non-contiguous in memory, i.e. the chroma plane do not
+necessarily immediately follows the luma plane. The luminance data
+occupies the first plane. The Y plane has one byte per pixel. In the
+second plane there is a chrominance data with alternating chroma
+samples. The CbCr plane is the same width, in bytes, as the Y plane (and
+of the image), but is half as tall in pixels. Each CbCr pair belongs to
+four pixels. For example, Cb\ :sub:`0`/Cr\ :sub:`0` belongs to
+Y'\ :sub:`00`, Y'\ :sub:`01`, Y'\ :sub:`10`, Y'\ :sub:`11`.
+``V4L2_PIX_FMT_NV12MT_16X16`` is the tiled version of
+``V4L2_PIX_FMT_NV12M`` with 16x16 macroblock tiles. Here pixels are
+arranged in 16x16 2D tiles and tiles are arranged in linear order in
+memory. ``V4L2_PIX_FMT_NV21M`` is the same as ``V4L2_PIX_FMT_NV12M``
+except the Cb and Cr bytes are swapped, the CrCb plane starts with a Cr
+byte.
+
+``V4L2_PIX_FMT_NV12M`` is intended to be used only in drivers and
+applications that support the multi-planar API, described in
+:ref:`planar-apis`.
+
+If the Y plane has pad bytes after each row, then the CbCr plane has as
+many pad bytes after its rows.
+
+**Byte Order.**
+Each cell is one byte.

+Formats with ½ horizontal and vertical chroma resolution. This format
+has two planes - one for luminance and one for chrominance. Chroma
+samples are interleaved. The difference to ``V4L2_PIX_FMT_NV12`` is the
+memory layout. Pixels are grouped in macroblocks of 64x32 size. The
+order of macroblocks in memory is also not standard.
+
+
+Description
+===========
+
+This is the two-plane versions of the YUV 4:2:0 format where data is
+grouped into 64x32 macroblocks. The three components are separated into
+two sub-images or planes. The Y plane has one byte per pixel and pixels
+are grouped into 64x32 macroblocks. The CbCr plane has the same width,
+in bytes, as the Y plane (and the image), but is half as tall in pixels.
+The chroma plane is also grouped into 64x32 macroblocks.
+
+Width of the buffer has to be aligned to the multiple of 128, and height
+alignment is 32. Every four adjacent buffers - two horizontally and two
+vertically are grouped together and are located in memory in Z or
+flipped Z order.
+
+Layout of macroblocks in memory is presented in the following figure.

+
+    V4L2_PIX_FMT_NV12MT macroblock Z shape memory layout
+
+The requirement that width is multiple of 128 is implemented because,
+the Z shape cannot be cut in half horizontally. In case the vertical
+resolution of macroblocks is odd then the last row of macroblocks is
+arranged in a linear order.
+
+In case of chroma the layout is identical. Cb and Cr samples are
+interleaved. Height of the buffer is aligned to 32.

+One luminance and one chrominance plane with alternating chroma samples

+
+
+Description
+===========
+
+These are two-plane versions of the YUV 4:2:2 format. The three
+components are separated into two sub-images or planes. The Y plane is
+first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_NV16``, a
+combined CbCr plane immediately follows the Y plane in memory. The CbCr
+plane is the same width and height, in bytes, as the Y plane (and of the
+image). Each CbCr pair belongs to two pixels. For example,
+Cb\ :sub:`0`/Cr\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`.
+``V4L2_PIX_FMT_NV61`` is the same except the Cb and Cr bytes are
+swapped, the CrCb plane starts with a Cr byte.
+
+If the Y plane has pad bytes after each row, then the CbCr plane has as
+many pad bytes after its rows.
+
+**Byte Order.**
+Each cell is one byte.

+V4L2_PIX_FMT_NV42
+Formats with full horizontal and vertical chroma resolutions, also known
+as YUV 4:4:4. One luminance and one chrominance plane with alternating
+chroma samples as opposed to ``V4L2_PIX_FMT_YVU420``
+
+
+Description
+===========
+
+These are two-plane versions of the YUV 4:4:4 format. The three
+components are separated into two sub-images or planes. The Y plane is
+first, with each Y sample stored in one byte per pixel. For
+``V4L2_PIX_FMT_NV24``, a combined CbCr plane immediately follows the Y
+plane in memory. The CbCr plane has the same width and height, in
+pixels, as the Y plane (and the image). Each line contains one CbCr pair
+per pixel, with each Cb and Cr sample stored in one byte.
+``V4L2_PIX_FMT_NV42`` is the same except that the Cb and Cr samples are
+swapped, the CrCb plane starts with a Cr sample.
+
+If the Y plane has pad bytes after each row, then the CbCr plane has
+twice as many pad bytes after its rows.
+
+**Byte Order.**
+Each cell is one byte.

+Description
+===========
+
+These formats are designed to match the pixel formats of typical PC
+graphics frame buffers. They occupy 8, 16, 24 or 32 bits per pixel.
+These are all packed-pixel formats, meaning all the data for a pixel lie
+next to each other in memory.

+Bit 7 is the most significant bit.
+
+The usage and value of the alpha bits (a) in the ARGB and ABGR formats
+(collectively referred to as alpha formats) depend on the device type
+and hardware operation. :ref:`Capture <capture>` devices (including
+capture queues of mem-to-mem devices) fill the alpha component in
+memory. When the device outputs an alpha channel the alpha component
+will have a meaningful value. Otherwise, when the device doesn't output
+an alpha channel but can set the alpha bit to a user-configurable value,
+the :ref:`V4L2_CID_ALPHA_COMPONENT <v4l2-alpha-component>` control
+is used to specify that alpha value, and the alpha component of all
+pixels will be set to the value specified by that control. Otherwise a
+corresponding format without an alpha component (XRGB or XBGR) must be
+used instead of an alpha format.
+
+:ref:`Output <output>` devices (including output queues of mem-to-mem
+devices and :ref:`video output overlay <osd>` devices) read the alpha
+component from memory. When the device processes the alpha channel the
+alpha component must be filled with meaningful values by applications.
+Otherwise a corresponding format without an alpha component (XRGB or
+XBGR) must be used instead of an alpha format.
+
+The XRGB and XBGR formats contain undefined bits (-). Applications,
+devices and drivers must ignore those bits, for both
+:ref:`capture` and :ref:`output` devices.
+
+**Byte Order.**

+
+       -  Two-planar format used by Samsung S5C73MX cameras. The first plane
+	  contains interleaved JPEG and UYVY image data, followed by meta
+	  data in form of an array of offsets to the UYVY data blocks. The
+	  actual pointer array follows immediately the interleaved JPEG/UYVY
+	  data, the number of entries in this array equals the height of the
+	  UYVY image. Each entry is a 4-byte unsigned integer in big endian
+	  order and it's an offset to a single pixel line of the UYVY image.
+	  The first plane can start either with JPEG or UYVY data chunk. The
+	  size of a single UYVY block equals the UYVY image's width
+	  multiplied by 2. The size of a JPEG chunk depends on the image and
+	  can vary with each line.
+
+	  The second plane, at an offset of 4084 bytes, contains a 4-byte
+	  offset to the pointer array in the first plane. This offset is
+	  followed by a 4-byte value indicating size of the pointer array.
+	  All numbers in the second plane are also in big endian order.
+	  Remaining data in the second plane is undefined. The information
+	  in the second plane allows to easily find location of the pointer
+	  array, which can be different for each frame. The size of the
+	  pointer array is constant for given UYVY image height.
+
+	  In order to extract UYVY and JPEG frames an application can
+	  initially set a data pointer to the start of first plane and then
+	  add an offset from the first entry of the pointers table. Such a
+	  pointer indicates start of an UYVY image pixel line. Whole UYVY
+	  line can be copied to a separate buffer. These steps should be
+	  repeated for each line, i.e. the number of entries in the pointer
+	  array. Anything what's in between the UYVY lines is JPEG data and
+	  should be concatenated to form the JPEG stream.

+Bayer RGB format
+
+
+Description
+===========
+
+This is commonly the native format of digital cameras, reflecting the
+arrangement of sensors on the CCD device. Only one red, green or blue
+value is given for each pixel. Missing components must be interpolated
+from neighbouring pixels. From left to right the first row consists of a
+green and blue value, the second row of a red and green value. This
+scheme repeats to the right and down for every two columns and rows.
+
+**Byte Order.**
+Each cell is one byte.

+Description
+===========
+
+These four pixel formats are raw sRGB / Bayer formats with 10 bits per
+colour. Each colour component is stored in a 16-bit word, with 6 unused
+high bits filled with zeros. Each n-pixel row contains n/2 green samples
+and n/2 blue or red samples, with alternating red and blue rows. Bytes
+are stored in memory in little endian order. They are conventionally
+described as GRGR... BGBG..., RGRG... GBGB..., etc. Below is an example

+Description
+===========
+
+This is a grey-scale image with a depth of 16 bits per pixel. The most
+significant byte is stored at lower memory addresses (big-endian).
+
+.. note:: Tthe actual sampling precision may be lower than 16 bits, for
+   example 10 bits per pixel with values in range 0 to 1023.
+
+**Byte Order.**
+Each cell is one byte.

+Format with ¼ horizontal chroma resolution, also known as YUV 4:1:1
+
+
+Description
+===========
+
+In this format each 12 bytes is eight pixels. In the twelve bytes are
+two CbCr pairs and eight Y's. The first CbCr pair goes with the first
+four Y's, and the second CbCr pair goes with the other four Y's. The Cb
+and Cr components have one fourth the horizontal resolution of the Y
+component.
+
+Do not confuse this format with
+:ref:`V4L2_PIX_FMT_YUV411P <V4L2-PIX-FMT-YUV411P>`. Y41P is derived
+from "YUV 4:1:1 *packed*", while YUV411P stands for "YUV 4:1:1
+*planar*".

+V4L2_PIX_FMT_YUV410
+Planar formats with ¼ horizontal and vertical chroma resolution, also
+known as YUV 4:1:0
+
+
+Description
+===========
+
+These are planar formats, as opposed to a packed format. The three
+components are separated into three sub-images or planes. The Y plane is
+first. The Y plane has one byte per pixel. For ``V4L2_PIX_FMT_YVU410``,
+the Cr plane immediately follows the Y plane in memory. The Cr plane is
+¼ the width and ¼ the height of the Y plane (and of the image). Each Cr
+belongs to 16 pixels, a four-by-four square of the image. Following the
+Cr plane is the Cb plane, just like the Cr plane.
+``V4L2_PIX_FMT_YUV410`` is the same, except the Cb plane comes first,
+then the Cr plane.
+
+If the Y plane has pad bytes after each row, then the Cr and Cb planes
+have ¼ as many pad bytes after their rows. In other words, four Cx rows
+(including padding) are exactly as long as one Y row (including
+padding).
+
+**Byte Order.**
+Each cell is one byte.

+Format with ¼ horizontal chroma resolution, also known as YUV 4:1:1.
+Planar layout as opposed to ``V4L2_PIX_FMT_Y41P``
+
+
+Description
+===========
+
+This format is not commonly used. This is a planar format similar to the
+4:2:2 planar format except with half as many chroma. The three
+components are separated into three sub-images or planes. The Y plane is
+first. The Y plane has one byte per pixel. The Cb plane immediately
+follows the Y plane in memory. The Cb plane is ¼ the width of the Y
+plane (and of the image). Each Cb belongs to 4 pixels all on the same
+row. For example, Cb\ :sub:`0` belongs to Y'\ :sub:`00`, Y'\ :sub:`01`,
+Y'\ :sub:`02` and Y'\ :sub:`03`. Following the Cb plane is the Cr plane,
+just like the Cb plane.
+
+If the Y plane has pad bytes after each row, then the Cr and Cb planes
+have ¼ as many pad bytes after their rows. In other words, four C x rows
+(including padding) is exactly as long as one Y row (including padding).
+
+**Byte Order.**
+Each cell is one byte.

+V4L2_PIX_FMT_YUV420
+Planar formats with ½ horizontal and vertical chroma resolution, also
+known as YUV 4:2:0
+
+
+Description
+===========
+
+These are planar formats, as opposed to a packed format. The three
+components are separated into three sub- images or planes. The Y plane
+is first. The Y plane has one byte per pixel. For
+``V4L2_PIX_FMT_YVU420``, the Cr plane immediately follows the Y plane in
+memory. The Cr plane is half the width and half the height of the Y
+plane (and of the image). Each Cr belongs to four pixels, a two-by-two
+square of the image. For example, Cr\ :sub:`0` belongs to Y'\ :sub:`00`,
+Y'\ :sub:`01`, Y'\ :sub:`10`, and Y'\ :sub:`11`. Following the Cr plane
+is the Cb plane, just like the Cr plane. ``V4L2_PIX_FMT_YUV420`` is the
+same except the Cb plane comes first, then the Cr plane.
+
+If the Y plane has pad bytes after each row, then the Cr and Cb planes
+have half as many pad bytes after their rows. In other words, two Cx
+rows (including padding) is exactly as long as one Y row (including
+padding).
+
+**Byte Order.**
+Each cell is one byte.

+Format with ½ horizontal chroma resolution, also known as YUV 4:2:2.
+Planar layout as opposed to ``V4L2_PIX_FMT_YUYV``
+
+
+Description
+===========
+
+This format is not commonly used. This is a planar version of the YUYV
+format. The three components are separated into three sub-images or
+planes. The Y plane is first. The Y plane has one byte per pixel. The Cb
+plane immediately follows the Y plane in memory. The Cb plane is half
+the width of the Y plane (and of the image). Each Cb belongs to two
+pixels. For example, Cb\ :sub:`0` belongs to Y'\ :sub:`00`,
+Y'\ :sub:`01`. Following the Cb plane is the Cr plane, just like the Cb
+plane.
+
+If the Y plane has pad bytes after each row, then the Cr and Cb planes
+have half as many pad bytes after their rows. In other words, two Cx
+rows (including padding) is exactly as long as one Y row (including
+padding).
+
+**Byte Order.**
+Each cell is one byte.

+Planar formats with full horizontal resolution, also known as YUV and
+YVU 4:4:4
+
+
+Description
+===========
+
+This is a multi-planar format, as opposed to a packed format. The three
+components are separated into three sub-images or planes.
+
+The Y plane is first. The Y plane has one byte per pixel. For
+``V4L2_PIX_FMT_YUV444M`` the Cb data constitutes the second plane which
+is the same width and height as the Y plane (and as the image). The Cr
+data, just like the Cb plane, is in the third plane.
+
+``V4L2_PIX_FMT_YVU444M`` is the same except the Cr data is stored in the
+second plane and the Cb data in the third plane.
+
+If the Y plane has pad bytes after each row, then the Cb and Cr planes
+have the same number of pad bytes after their rows.
+
+``V4L2_PIX_FMT_YUV444M`` and ``V4L2_PIX_FMT_YUV444M`` are intended to be
+used only in drivers and applications that support the multi-planar API,
+described in :ref:`planar-apis`.

+
+In this format each four bytes is two pixels. Each four bytes is two
+Y's, a Cb and a Cr. Each Y goes to one of the pixels, and the Cb and Cr
+belong to both pixels. As you can see, the Cr and Cb components have

+The V4L2 API was primarily designed for devices exchanging image data
+with applications. The :ref:`struct v4l2_pix_format <v4l2-pix-format>` and
+:ref:`struct v4l2_pix_format_mplane <v4l2-pix-format-mplane>` structures define the
+format and layout of an image in memory. The former is used with the
+single-planar API, while the latter is used with the multi-planar
+version (see :ref:`planar-apis`). Image formats are negotiated with
+the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl. (The explanations here
+focus on video capturing and output, for overlay frame buffer formats
+see also :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`.)

+*****************************
+Single- and multi-planar APIs
+*****************************
+
+Some devices require data for each input or output video frame to be
+placed in discontiguous memory buffers. In such cases, one video frame
+has to be addressed using more than one memory address, i.e. one pointer
+per "plane". A plane is a sub-buffer of the current frame. For examples
+of such formats see :ref:`pixfmt`.
+
+Initially, V4L2 API did not support multi-planar buffers and a set of
+extensions has been introduced to handle them. Those extensions
+constitute what is being referred to as the "multi-planar API".
+
+Some of the V4L2 API calls and structures are interpreted differently,
+depending on whether single- or multi-planar API is being used. An
+application can choose whether to use one or the other by passing a
+corresponding buffer type to its ioctl calls. Multi-planar versions of
+buffer types are suffixed with an ``_MPLANE`` string. For a list of
+available multi-planar buffer types see enum
+:ref:`v4l2_buf_type <v4l2-buf-type>`.
+
+
+Multi-planar formats
+====================
+
+Multi-planar API introduces new multi-planar formats. Those formats use
+a separate set of FourCC codes. It is important to distinguish between
+the multi-planar API and a multi-planar format. Multi-planar API calls
+can handle all single-planar formats as well (as long as they are passed
+in multi-planar API structures), while the single-planar API cannot
+handle multi-planar formats.
+
+
+Calls that distinguish between single and multi-planar APIs
+===========================================================
+
+:ref:`VIDIOC_QUERYCAP <VIDIOC_QUERYCAP>`
+    Two additional multi-planar capabilities are added. They can be set
+    together with non-multi-planar ones for devices that handle both
+    single- and multi-planar formats.
+
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`, :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>`
+    New structures for describing multi-planar formats are added: struct
+    :ref:`v4l2_pix_format_mplane <v4l2-pix-format-mplane>` and
+    struct :ref:`v4l2_plane_pix_format <v4l2-plane-pix-format>`.
+    Drivers may define new multi-planar formats, which have distinct
+    FourCC codes from the existing single-planar ones.
+
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_QUERYBUF <VIDIOC_QUERYBUF>`
+    A new struct :ref:`v4l2_plane <v4l2-plane>` structure for
+    describing planes is added. Arrays of this structure are passed in
+    the new ``m.planes`` field of struct
+    :ref:`v4l2_buffer <v4l2-buffer>`.
+
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`
+    Will allocate multi-planar buffers as requested.

+*********************
+Querying Capabilities
+*********************
+
+Because V4L2 covers a wide variety of devices not all aspects of the API
+are equally applicable to all types of devices. Furthermore devices of
+the same type have different capabilities and this specification permits
+the omission of a few complicated and less important parts of the API.
+
+The :ref:`VIDIOC_QUERYCAP` ioctl is available to
+check if the kernel device is compatible with this specification, and to
+query the :ref:`functions <devices>` and :ref:`I/O methods <io>`
+supported by the device.
+
+Starting with kernel version 3.1, :ref:`VIDIOC_QUERYCAP`
+will return the V4L2 API version used by the driver, with generally
+matches the Kernel version. There's no need of using
+:ref:`VIDIOC_QUERYCAP` to check if a specific ioctl
+is supported, the V4L2 core now returns ``ENOTTY`` if a driver doesn't
+provide support for an ioctl.
+
+Other features can be queried by calling the respective ioctl, for
+example :ref:`VIDIOC_ENUMINPUT` to learn about the
+number, types and names of video connectors on the device. Although
+abstraction is a major objective of this API, the
+:ref:`VIDIOC_QUERYCAP` ioctl also allows driver
+specific applications to reliably identify the driver.
+
+All V4L2 drivers must support :ref:`VIDIOC_QUERYCAP`.
+Applications should always call this ioctl after opening the device.

+Input and output devices support the :ref:`read() <func-read>` and
+:ref:`write() <func-write>` function, respectively, when the
+``V4L2_CAP_READWRITE`` flag in the ``capabilities`` field of struct
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl is set.
+
+Drivers may need the CPU to copy the data, but they may also support DMA
+to or from user memory, so this I/O method is not necessarily less
+efficient than other methods merely exchanging buffer pointers. It is
+considered inferior though because no meta-information like frame
+counters or timestamps are passed. This information is necessary to
+recognize frame dropping and to synchronize with other data streams.
+However this is also the simplest I/O method, requiring little or no
+setup to exchange data. It permits command line stunts like this (the
+vidctrl tool is fictitious):
+
+
+.. code-block:: none
+
+    $ vidctrl /dev/video --input=0 --format=YUYV --size=352x288
+    $ dd if=/dev/video of=myimage.422 bs=202752 count=1
+
+To read from the device applications use the :ref:`read() <func-read>`
+function, to write the :ref:`write() <func-write>` function. Drivers
+must implement one I/O method if they exchange data with applications,
+but it need not be this. [#f1]_ When reading or writing is supported, the
+driver must also support the :ref:`select() <func-select>` and
+:ref:`poll() <func-poll>` function. [#f2]_
+
+.. [#f1]
+   It would be desirable if applications could depend on drivers
+   supporting all I/O interfaces, but as much as the complex memory
+   mapping I/O can be inadequate for some devices we have no reason to
+   require this interface, which is most useful for simple applications
+   capturing still images.
+
+.. [#f2]
+   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
+   the same, and :ref:`select() <func-select>` is too important to be optional.

+Introduction
+************
+
+Some video capture devices can sample a subsection of a picture and
+shrink or enlarge it to an image of arbitrary size. Next, the devices
+can insert the image into larger one. Some video output devices can crop
+part of an input image, scale it up or down and insert it at an
+arbitrary scan line and horizontal offset into a video signal. We call
+these abilities cropping, scaling and composing.
+
+On a video *capture* device the source is a video signal, and the
+cropping target determine the area actually sampled. The sink is an
+image stored in a memory buffer. The composing area specifies which part
+of the buffer is actually written to by the hardware.
+
+On a video *output* device the source is an image in a memory buffer,
+and the cropping target is a part of an image to be shown on a display.
+The sink is the display or the graphics screen. The application may
+select the part of display where the image should be displayed. The size
+and position of such a window is controlled by the compose target.
+
+Rectangles for all cropping and composing targets are defined even if
+the device does supports neither cropping nor composing. Their size and
+position will be fixed in such a case. If the device does not support
+scaling then the cropping and composing rectangles have the same size.

+*************
+Configuration
+*************
+
+Applications can use the :ref:`selection API <VIDIOC_G_SELECTION>` to
+select an area in a video signal or a buffer, and to query for default
+settings and hardware limits.
+
+Video hardware can have various cropping, composing and scaling
+limitations. It may only scale up or down, support only discrete scaling
+factors, or have different scaling abilities in the horizontal and
+vertical directions. Also it may not support scaling at all. At the same
+time the cropping/composing rectangles may have to be aligned, and both
+the source and the sink may have arbitrary upper and lower size limits.
+Therefore, as usual, drivers are expected to adjust the requested
+parameters and return the actual values selected. An application can
+control the rounding behaviour using
+:ref:`constraint flags <v4l2-selection-flags>`.
+
+
+Configuration of video capture
+==============================
+
+See figure :ref:`sel-targets-capture` for examples of the selection
+targets available for a video capture device. It is recommended to
+configure the cropping targets before to the composing targets.
+
+The range of coordinates of the top left corner, width and height of
+areas that can be sampled is given by the ``V4L2_SEL_TGT_CROP_BOUNDS``
+target. It is recommended for the driver developers to put the top/left
+corner at position ``(0,0)``. The rectangle's coordinates are expressed
+in pixels.
+
+The top left corner, width and height of the source rectangle, that is
+the area actually sampled, is given by the ``V4L2_SEL_TGT_CROP`` target.
+It uses the same coordinate system as ``V4L2_SEL_TGT_CROP_BOUNDS``. The
+active cropping area must lie completely inside the capture boundaries.
+The driver may further adjust the requested size and/or position
+according to hardware limitations.
+
+Each capture device has a default source rectangle, given by the
+``V4L2_SEL_TGT_CROP_DEFAULT`` target. This rectangle shall over what the
+driver writer considers the complete picture. Drivers shall set the
+active crop rectangle to the default when the driver is first loaded,
+but not later.
+
+The composing targets refer to a memory buffer. The limits of composing
+coordinates are obtained using ``V4L2_SEL_TGT_COMPOSE_BOUNDS``. All
+coordinates are expressed in pixels. The rectangle's top/left corner
+must be located at position ``(0,0)``. The width and height are equal to
+the image size set by :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`.
+
+The part of a buffer into which the image is inserted by the hardware is
+controlled by the ``V4L2_SEL_TGT_COMPOSE`` target. The rectangle's
+coordinates are also expressed in the same coordinate system as the
+bounds rectangle. The composing rectangle must lie completely inside
+bounds rectangle. The driver must adjust the composing rectangle to fit
+to the bounding limits. Moreover, the driver can perform other
+adjustments according to hardware limitations. The application can
+control rounding behaviour using
+:ref:`constraint flags <v4l2-selection-flags>`.
+
+For capture devices the default composing rectangle is queried using
+``V4L2_SEL_TGT_COMPOSE_DEFAULT``. It is usually equal to the bounding
+rectangle.
+
+The part of a buffer that is modified by the hardware is given by
+``V4L2_SEL_TGT_COMPOSE_PADDED``. It contains all pixels defined using
+``V4L2_SEL_TGT_COMPOSE`` plus all padding data modified by hardware
+during insertion process. All pixels outside this rectangle *must not*
+be changed by the hardware. The content of pixels that lie inside the
+padded area but outside active area is undefined. The application can
+use the padded and active rectangles to detect where the rubbish pixels
+are located and remove them if needed.
+
+
+Configuration of video output
+=============================
+
+For output devices targets and ioctls are used similarly to the video
+capture case. The *composing* rectangle refers to the insertion of an
+image into a video signal. The cropping rectangles refer to a memory
+buffer. It is recommended to configure the composing targets before to
+the cropping targets.
+
+The cropping targets refer to the memory buffer that contains an image
+to be inserted into a video signal or graphical screen. The limits of
+cropping coordinates are obtained using ``V4L2_SEL_TGT_CROP_BOUNDS``.
+All coordinates are expressed in pixels. The top/left corner is always
+point ``(0,0)``. The width and height is equal to the image size
+specified using :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl.
+
+The top left corner, width and height of the source rectangle, that is
+the area from which image date are processed by the hardware, is given
+by the ``V4L2_SEL_TGT_CROP``. Its coordinates are expressed in in the
+same coordinate system as the bounds rectangle. The active cropping area
+must lie completely inside the crop boundaries and the driver may
+further adjust the requested size and/or position according to hardware
+limitations.
+
+For output devices the default cropping rectangle is queried using
+``V4L2_SEL_TGT_CROP_DEFAULT``. It is usually equal to the bounding
+rectangle.
+
+The part of a video signal or graphics display where the image is
+inserted by the hardware is controlled by ``V4L2_SEL_TGT_COMPOSE``
+target. The rectangle's coordinates are expressed in pixels. The
+composing rectangle must lie completely inside the bounds rectangle. The
+driver must adjust the area to fit to the bounding limits. Moreover, the
+driver can perform other adjustments according to hardware limitations.
+
+The device has a default composing rectangle, given by the
+``V4L2_SEL_TGT_COMPOSE_DEFAULT`` target. This rectangle shall cover what
+the driver writer considers the complete picture. It is recommended for
+the driver developers to put the top/left corner at position ``(0,0)``.
+Drivers shall set the active composing rectangle to the default one when
+the driver is first loaded.
+
+The devices may introduce additional content to video signal other than
+an image from memory buffers. It includes borders around an image.
+However, such a padded area is driver-dependent feature not covered by
+this document. Driver developers are encouraged to keep padded rectangle
+equal to active one. The padded target is accessed by the
+``V4L2_SEL_TGT_COMPOSE_PADDED`` identifier. It must contain all pixels
+from the ``V4L2_SEL_TGT_COMPOSE`` target.
+
+
+Scaling control
+===============
+
+An application can detect if scaling is performed by comparing the width
+and the height of rectangles obtained using ``V4L2_SEL_TGT_CROP`` and
+``V4L2_SEL_TGT_COMPOSE`` targets. If these are not equal then the
+scaling is applied. The application can compute the scaling ratios using
+these values.

+********************************
+Comparison with old cropping API
+********************************
+
+The selection API was introduced to cope with deficiencies of previous
+:ref:`API <crop>`, that was designed to control simple capture
+devices. Later the cropping API was adopted by video output drivers. The
+ioctls are used to select a part of the display were the video signal is
+inserted. It should be considered as an API abuse because the described
+operation is actually the composing. The selection API makes a clear
+distinction between composing and cropping operations by setting the
+appropriate targets. The V4L2 API lacks any support for composing to and
+cropping from an image inside a memory buffer. The application could
+configure a capture device to fill only a part of an image by abusing
+V4L2 API. Cropping a smaller image from a larger one is achieved by
+setting the field ``bytesperline`` at struct
+:ref:`v4l2_pix_format <v4l2-pix-format>`.
+Introducing an image offsets could be done by modifying field ``m_userptr``
+at struct
+:ref:`v4l2_buffer <v4l2-buffer>` before calling
+:ref:`VIDIOC_QBUF`. Those operations should be avoided because they are not
+portable (endianness), and do not work for macroblock and Bayer formats
+and mmap buffers. The selection API deals with configuration of buffer
+cropping/composing in a clear, intuitive and portable way. Next, with
+the selection API the concepts of the padded target and constraints
+flags are introduced. Finally, struct :ref:`v4l2_crop <v4l2-crop>`
+and struct :ref:`v4l2_cropcap <v4l2-cropcap>` have no reserved
+fields. Therefore there is no way to extend their functionality. The new
+struct :ref:`v4l2_selection <v4l2-selection>` provides a lot of place
+for future extensions. Driver developers are encouraged to implement
+only selection API. The former cropping API would be simulated using the
+new one.

+***************
+Video Standards
+***************
+
+Video devices typically support one or more different video standards or
+variations of standards. Each video input and output may support another
+set of standards. This set is reported by the ``std`` field of struct
+:ref:`v4l2_input <v4l2-input>` and struct
+:ref:`v4l2_output <v4l2-output>` returned by the
+:ref:`VIDIOC_ENUMINPUT` and
+:ref:`VIDIOC_ENUMOUTPUT` ioctls, respectively.
+
+V4L2 defines one bit for each analog video standard currently in use
+worldwide, and sets aside bits for driver defined standards, e. g.
+hybrid standards to watch NTSC video tapes on PAL TVs and vice versa.
+Applications can use the predefined bits to select a particular
+standard, although presenting the user a menu of supported standards is
+preferred. To enumerate and query the attributes of the supported
+standards applications use the :ref:`VIDIOC_ENUMSTD`
+ioctl.
+
+Many of the defined standards are actually just variations of a few
+major standards. The hardware may in fact not distinguish between them,
+or do so internal and switch automatically. Therefore enumerated
+standards also contain sets of one or more standard bits.
+
+Assume a hypothetic tuner capable of demodulating B/PAL, G/PAL and I/PAL
+signals. The first enumerated standard is a set of B and G/PAL, switched
+automatically depending on the selected radio frequency in UHF or VHF
+band. Enumeration gives a "PAL-B/G" or "PAL-I" choice. Similar a
+Composite input may collapse standards, enumerating "PAL-B/G/H/I",
+"NTSC-M" and "SECAM-D/K". [#f1]_
+
+To query and select the standard used by the current video input or
+output applications call the :ref:`VIDIOC_G_STD <VIDIOC_G_STD>` and
+:ref:`VIDIOC_S_STD <VIDIOC_G_STD>` ioctl, respectively. The
+*received* standard can be sensed with the
+:ref:`VIDIOC_QUERYSTD` ioctl.
+
+..note:: The parameter of all these ioctls is a pointer to a
+   :ref:`v4l2_std_id <v4l2-std-id>` type (a standard set), *not* an
+   index into the standard enumeration. Drivers must implement all video
+   standard ioctls when the device has one or more video inputs or outputs.
+
+Special rules apply to devices such as USB cameras where the notion of
+video standards makes little sense. More generally for any capture or
+output device which is:
+
+-  incapable of capturing fields or frames at the nominal rate of the
+   video standard, or
+
+-  that does not support the video standard formats at all.
+
+Here the driver shall set the ``std`` field of struct
+:ref:`v4l2_input <v4l2-input>` and struct
+:ref:`v4l2_output <v4l2-output>` to zero and the :ref:`VIDIOC_G_STD <VIDIOC_G_STD>`,
+:ref:`VIDIOC_S_STD <VIDIOC_G_STD>`, :ref:`VIDIOC_QUERYSTD` and :ref:`VIDIOC_ENUMSTD` ioctls
+shall return the ``ENOTTY`` error code or the ``EINVAL`` error code.
+
+Applications can make use of the :ref:`input-capabilities` and
+:ref:`output-capabilities` flags to determine whether the video
+standard ioctls can be used with the given input or output.
+

+Streaming Parameters
+********************
+
+Streaming parameters are intended to optimize the video capture process
+as well as I/O. Presently applications can request a high quality
+capture mode with the :ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl.
+
+The current video standard determines a nominal number of frames per
+second. If less than this number of frames is to be captured or output,
+applications can request frame skipping or duplicating on the driver
+side. This is especially useful when using the
+:ref:`read() <func-read>` or :ref:`write() <func-write>`, which are
+not augmented by timestamps or sequence counters, and to avoid
+unnecessary data copying.
+
+Finally these ioctls can be used to determine the number of buffers used
+internally by a driver in read/write mode. For implications see the
+section discussing the :ref:`read() <func-read>` function.
+
+To get and set the streaming parameters applications call the
+:ref:`VIDIOC_G_PARM <VIDIOC_G_PARM>` and
+:ref:`VIDIOC_S_PARM <VIDIOC_G_PARM>` ioctl, respectively. They take
+a pointer to a struct :ref:`v4l2_streamparm <v4l2-streamparm>`, which
+contains a union holding separate parameters for input and output
+devices.
+
+These ioctls are optional, drivers need not implement them. If so, they
+return the ``EINVAL`` error code.

+Media Bus Pixel Codes
+---------------------
+
+The media bus pixel codes describe image formats as flowing over
+physical busses (both between separate physical components and inside
+SoC devices). This should not be confused with the V4L2 pixel formats
+that describe, using four character codes, image formats as stored in
+memory.
+
+While there is a relationship between image formats on busses and image
+formats in memory (a raw Bayer image won't be magically converted to
+JPEG just by storing it to memory), there is no one-to-one
+correspondance between them.
+
+
+Packed RGB Formats
+^^^^^^^^^^^^^^^^^^
+
+Those formats transfer pixel data as red, green and blue components. The
+format code is made of the following information.
+
+-  The red, green and blue components order code, as encoded in a pixel
+   sample. Possible values are RGB and BGR.
+
+-  The number of bits per component, for each component. The values can
+   be different for all components. Common values are 555 and 565.
+
+-  The number of bus samples per pixel. Pixels that are wider than the
+   bus width must be transferred in multiple samples. Common values are
+   1 and 2.
+
+-  The bus width.
+
+-  For formats where the total number of bits per pixel is smaller than
+   the number of bus samples per pixel times the bus width, a padding
+   value stating if the bytes are padded in their most high order bits
+   (PADHI) or low order bits (PADLO). A "C" prefix is used for
+   component-wise padding in the most high order bits (CPADHI) or low
+   order bits (CPADLO) of each separate component.
+
+-  For formats where the number of bus samples per pixel is larger than
+   1, an endianness value stating if the pixel is transferred MSB first
+   (BE) or LSB first (LE).
+
+For instance, a format where pixels are encoded as 5-bits red, 5-bits
+green and 5-bit blue values padded on the high bit, transferred as 2
+8-bit samples per pixel with the most significant bits (padding, red and
+half of the green value) transferred first will be named
+``MEDIA_BUS_FMT_RGB555_2X8_PADHI_BE``.

+On LVDS buses, usually each sample is transferred serialized in seven
+time slots per pixel clock, on three (18-bit) or four (24-bit)
+differential data pairs at the same time. The remaining bits are used
+for control signals as defined by SPWG/PSWG/VESA or JEIDA standards. The
+24-bit RGB format serialized in seven time slots on four lanes using
+JEIDA defined bit mapping will be named
+``MEDIA_BUS_FMT_RGB888_1X7X4_JEIDA``, for example.

+Bayer Formats
+^^^^^^^^^^^^^
+
+Those formats transfer pixel data as red, green and blue components. The
+format code is made of the following information.
+
+-  The red, green and blue components order code, as encoded in a pixel
+   sample. The possible values are shown in :ref:`bayer-patterns`.
+
+-  The number of bits per pixel component. All components are
+   transferred on the same number of bits. Common values are 8, 10 and
+   12.
+
+-  The compression (optional). If the pixel components are ALAW- or
+   DPCM-compressed, a mention of the compression scheme and the number
+   of bits per compressed pixel component.
+
+-  The number of bus samples per pixel. Pixels that are wider than the
+   bus width must be transferred in multiple samples. Common values are
+   1 and 2.
+
+-  The bus width.
+
+-  For formats where the total number of bits per pixel is smaller than
+   the number of bus samples per pixel times the bus width, a padding
+   value stating if the bytes are padded in their most high order bits
+   (PADHI) or low order bits (PADLO).
+
+-  For formats where the number of bus samples per pixel is larger than
+   1, an endianness value stating if the pixel is transferred MSB first
+   (BE) or LSB first (LE).
+
+For instance, a format with uncompressed 10-bit Bayer components
+arranged in a red, green, green, blue pattern transferred as 2 8-bit
+samples per pixel with the least significant bits transferred first will
+be named ``MEDIA_BUS_FMT_SRGGB10_2X8_PADHI_LE``.

+Packed YUV Formats
+^^^^^^^^^^^^^^^^^^
+
+Those data formats transfer pixel data as (possibly downsampled) Y, U
+and V components. Some formats include dummy bits in some of their
+samples and are collectively referred to as "YDYC" (Y-Dummy-Y-Chroma)
+formats. One cannot rely on the values of these dummy bits as those are
+undefined.
+
+The format code is made of the following information.
+
+-  The Y, U and V components order code, as transferred on the bus.
+   Possible values are YUYV, UYVY, YVYU and VYUY for formats with no
+   dummy bit, and YDYUYDYV, YDYVYDYU, YUYDYVYD and YVYDYUYD for YDYC
+   formats.
+
+-  The number of bits per pixel component. All components are
+   transferred on the same number of bits. Common values are 8, 10 and
+   12.
+
+-  The number of bus samples per pixel. Pixels that are wider than the
+   bus width must be transferred in multiple samples. Common values are
+   1, 1.5 (encoded as 1_5) and 2.
+
+-  The bus width. When the bus width is larger than the number of bits
+   per pixel component, several components are packed in a single bus
+   sample. The components are ordered as specified by the order code,
+   with components on the left of the code transferred in the high order
+   bits. Common values are 8 and 16.
+
+For instance, a format where pixels are encoded as 8-bit YUV values
+downsampled to 4:2:2 and transferred as 2 8-bit bus samples per pixel in
+the U, Y, V, Y order will be named ``MEDIA_BUS_FMT_UYVY8_2X8``.
+
+:ref:`v4l2-mbus-pixelcode-yuv8` lists existing packed YUV formats and
+describes the organization of each pixel data in each sample. When a
+format pattern is split across multiple samples each of the samples in
+the pattern is described.
+
+The role of each bit transferred over the bus is identified by one of
+the following codes.
+
+-  y\ :sub:`x` for luma component bit number x
+
+-  u\ :sub:`x` for blue chroma component bit number x
+
+-  v\ :sub:`x` for red chroma component bit number x
+
+-  a\ :sub:`x` for alpha component bit number x
+
+-  - for non-available bits (for positions higher than the bus width)
+
+-  d for dummy bits

+HSV/HSL Formats
+^^^^^^^^^^^^^^^
+
+Those formats transfer pixel data as RGB values in a
+cylindrical-coordinate system using Hue-Saturation-Value or
+Hue-Saturation-Lightness components. The format code is made of the
+following information.
+
+-  The hue, saturation, value or lightness and optional alpha components
+   order code, as encoded in a pixel sample. The only currently
+   supported value is AHSV.
+
+-  The number of bits per component, for each component. The values can
+   be different for all components. The only currently supported value
+   is 8888.
+
+-  The number of bus samples per pixel. Pixels that are wider than the
+   bus width must be transferred in multiple samples. The only currently
+   supported value is 1.
+
+-  The bus width.
+
+-  For formats where the total number of bits per pixel is smaller than
+   the number of bus samples per pixel times the bus width, a padding
+   value stating if the bytes are padded in their most high order bits
+   (PADHI) or low order bits (PADLO).
+
+-  For formats where the number of bus samples per pixel is larger than
+   1, an endianness value stating if the pixel is transferred MSB first
+   (BE) or LSB first (LE).
+
+The following table lists existing HSV/HSL formats.

+JPEG Compressed Formats
+^^^^^^^^^^^^^^^^^^^^^^^
+
+Those data formats consist of an ordered sequence of 8-bit bytes
+obtained from JPEG compression process. Additionally to the ``_JPEG``
+postfix the format code is made of the following information.
+
+-  The number of bus samples per entropy encoded byte.
+
+-  The bus width.
+
+For instance, for a JPEG baseline process and an 8-bit bus width the
+format will be named ``MEDIA_BUS_FMT_JPEG_1X8``.
+
+The following table lists existing JPEG compressed formats.

+Tuners
+======
+
+Video input devices can have one or more tuners demodulating a RF
+signal. Each tuner is associated with one or more video inputs,
+depending on the number of RF connectors on the tuner. The ``type``
+field of the respective struct :ref:`v4l2_input <v4l2-input>`
+returned by the :ref:`VIDIOC_ENUMINPUT` ioctl is
+set to ``V4L2_INPUT_TYPE_TUNER`` and its ``tuner`` field contains the
+index number of the tuner.
+
+Radio input devices have exactly one tuner with index zero, no video
+inputs.
+
+To query and change tuner properties applications use the
+:ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>` and
+:ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` ioctls, respectively. The
+struct :ref:`v4l2_tuner <v4l2-tuner>` returned by :ref:`VIDIOC_G_TUNER <VIDIOC_G_TUNER>`
+also contains signal status information applicable when the tuner of the
+current video or radio input is queried.
+
+.. note:: :ref:`VIDIOC_S_TUNER <VIDIOC_G_TUNER>` does not switch the
+   current tuner, when there is more than one at all. The tuner is solely
+   determined by the current video input. Drivers must support both ioctls
+   and set the ``V4L2_CAP_TUNER`` flag in the struct :ref:`v4l2_capability
+   <v4l2-capability>` returned by the :ref:`VIDIOC_QUERYCAP` ioctl when the
+   device has one or more tuners.
+
+
+Modulators
+==========
+
+Video output devices can have one or more modulators, uh, modulating a
+video signal for radiation or connection to the antenna input of a TV
+set or video recorder. Each modulator is associated with one or more
+video outputs, depending on the number of RF connectors on the
+modulator. The ``type`` field of the respective struct
+:ref:`v4l2_output <v4l2-output>` returned by the
+:ref:`VIDIOC_ENUMOUTPUT` ioctl is set to
+``V4L2_OUTPUT_TYPE_MODULATOR`` and its ``modulator`` field contains the
+index number of the modulator.
+
+Radio output devices have exactly one modulator with index zero, no
+video outputs.
+
+A video or radio device cannot support both a tuner and a modulator. Two
+separate device nodes will have to be used for such hardware, one that
+supports the tuner functionality and one that supports the modulator
+functionality. The reason is a limitation with the
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl where you
+cannot specify whether the frequency is for a tuner or a modulator.
+
+To query and change modulator properties applications use the
+:ref:`VIDIOC_G_MODULATOR <VIDIOC_G_MODULATOR>` and
+:ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` ioctl. Note that
+:ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` does not switch the current modulator, when there
+is more than one at all. The modulator is solely determined by the
+current video output. Drivers must support both ioctls and set the
+``V4L2_CAP_MODULATOR`` flag in the struct
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl when the device has
+one or more modulators.
+
+
+Radio Frequency
+===============
+
+To get and set the tuner or modulator radio frequency applications use
+the :ref:`VIDIOC_G_FREQUENCY <VIDIOC_G_FREQUENCY>` and
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl which both take
+a pointer to a struct :ref:`v4l2_frequency <v4l2-frequency>`. These
+ioctls are used for TV and radio devices alike. Drivers must support
+both ioctls when the tuner or modulator ioctls are supported, or when
+the device is a radio device.

+*****************************
+Streaming I/O (User Pointers)
+*****************************
+
+Input and output devices support this I/O method when the
+``V4L2_CAP_STREAMING`` flag in the ``capabilities`` field of struct
+:ref:`v4l2_capability <v4l2-capability>` returned by the
+:ref:`VIDIOC_QUERYCAP` ioctl is set. If the
+particular user pointer method (not only memory mapping) is supported
+must be determined by calling the :ref:`VIDIOC_REQBUFS` ioctl
+with the memory type set to ``V4L2_MEMORY_USERPTR``.
+
+This I/O method combines advantages of the read/write and memory mapping
+methods. Buffers (planes) are allocated by the application itself, and
+can reside for example in virtual or shared memory. Only pointers to
+data are exchanged, these pointers and meta-information are passed in
+struct :ref:`v4l2_buffer <v4l2-buffer>` (or in struct
+:ref:`v4l2_plane <v4l2-plane>` in the multi-planar API case). The
+driver must be switched into user pointer I/O mode by calling the
+:ref:`VIDIOC_REQBUFS` with the desired buffer type.
+No buffers (planes) are allocated beforehand, consequently they are not
+indexed and cannot be queried like mapped buffers with the
+:ref:`VIDIOC_QUERYBUF <VIDIOC_QUERYBUF>` ioctl.
+
+Example: Initiating streaming I/O with user pointers
+====================================================
+
+.. code-block:: c
+
+    struct v4l2_requestbuffers reqbuf;
+
+    memset (&reqbuf, 0, sizeof (reqbuf));
+    reqbuf.type = V4L2_BUF_TYPE_VIDEO_CAPTURE;
+    reqbuf.memory = V4L2_MEMORY_USERPTR;
+
+    if (ioctl (fd, VIDIOC_REQBUFS, &reqbuf) == -1) {
+	if (errno == EINVAL)
+	    printf ("Video capturing or user pointer streaming is not supported\\n");
+	else
+	    perror ("VIDIOC_REQBUFS");
+
+	exit (EXIT_FAILURE);
+    }
+
+Buffer (plane) addresses and sizes are passed on the fly with the
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` ioctl. Although buffers are commonly
+cycled, applications can pass different addresses and sizes at each
+:ref:`VIDIOC_QBUF <VIDIOC_QBUF>` call. If required by the hardware the
+driver swaps memory pages within physical memory to create a continuous
+area of memory. This happens transparently to the application in the
+virtual memory subsystem of the kernel. When buffer pages have been
+swapped out to disk they are brought back and finally locked in physical
+memory for DMA. [#f1]_
+
+Filled or displayed buffers are dequeued with the
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl. The driver can unlock the
+memory pages at any time between the completion of the DMA and this
+ioctl. The memory is also unlocked when
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` is called,
+:ref:`VIDIOC_REQBUFS`, or when the device is closed.
+Applications must take care not to free buffers without dequeuing. For
+once, the buffers remain locked until further, wasting physical memory.
+Second the driver will not be notified when the memory is returned to
+the application's free list and subsequently reused for other purposes,
+possibly completing the requested DMA and overwriting valuable data.
+
+For capturing applications it is customary to enqueue a number of empty
+buffers, to start capturing and enter the read loop. Here the
+application waits until a filled buffer can be dequeued, and re-enqueues
+the buffer when the data is no longer needed. Output applications fill
+and enqueue buffers, when enough buffers are stacked up output is
+started. In the write loop, when the application runs out of free
+buffers it must wait until an empty buffer can be dequeued and reused.
+Two methods exist to suspend execution of the application until one or
+more buffers can be dequeued. By default :ref:`VIDIOC_DQBUF
+<VIDIOC_QBUF>` blocks when no buffer is in the outgoing queue. When the
+``O_NONBLOCK`` flag was given to the :ref:`open() <func-open>` function,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` returns immediately with an ``EAGAIN``
+error code when no buffer is available. The :ref:`select()
+<func-select>` or :ref:`poll() <func-poll>` function are always
+available.
+
+To start and stop capturing or output applications call the
+:ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>` and
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctl.
+
+.. note:: ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` removes all buffers from
+   both queues and unlocks all buffers as a side effect. Since there is no
+   notion of doing anything "now" on a multitasking system, if an
+   application needs to synchronize with another event it should examine
+   the struct :ref:`v4l2_buffer <v4l2-buffer>` ``timestamp`` of captured or
+   outputted buffers.
+
+Drivers implementing user pointer I/O must support the
+:ref:`VIDIOC_REQBUFS <VIDIOC_REQBUFS>`, :ref:`VIDIOC_QBUF <VIDIOC_QBUF>`,
+:ref:`VIDIOC_DQBUF <VIDIOC_QBUF>`, :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
+and :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` ioctls, the
+:ref:`select() <func-select>` and :ref:`poll() <func-poll>` function. [#f2]_
+
+.. [#f1]
+   We expect that frequently used buffers are typically not swapped out.
+   Anyway, the process of swapping, locking or generating scatter-gather
+   lists may be time consuming. The delay can be masked by the depth of
+   the incoming buffer queue, and perhaps by maintaining caches assuming
+   a buffer will be soon enqueued again. On the other hand, to optimize
+   memory usage drivers can limit the number of buffers locked in
+   advance and recycle the most recently used buffers first. Of course,
+   the pages of empty buffers in the incoming queue need not be saved to
+   disk. Output buffers must be saved on the incoming and outgoing queue
+   because an application may share them with other processes.
+
+.. [#f2]
+   At the driver level :ref:`select() <func-select>` and :ref:`poll() <func-poll>` are
+   the same, and :ref:`select() <func-select>` is too important to be optional.
+   The rest should be evident.

+Video Inputs and Outputs
+************************
+
+Video inputs and outputs are physical connectors of a device. These can
+be for example RF connectors (antenna/cable), CVBS a.k.a. Composite
+Video, S-Video or RGB connectors. Video and VBI capture devices have
+inputs. Video and VBI output devices have outputs, at least one each.
+Radio devices have no video inputs or outputs.
+
+To learn about the number and attributes of the available inputs and
+outputs applications can enumerate them with the
+:ref:`VIDIOC_ENUMINPUT` and
+:ref:`VIDIOC_ENUMOUTPUT` ioctl, respectively. The
+struct :ref:`v4l2_input <v4l2-input>` returned by the
+:ref:`VIDIOC_ENUMINPUT` ioctl also contains signal
+:status information applicable when the current video input is queried.
+
+The :ref:`VIDIOC_G_INPUT <VIDIOC_G_INPUT>` and
+:ref:`VIDIOC_G_OUTPUT <VIDIOC_G_OUTPUT>` ioctls return the index of
+the current video input or output. To select a different input or output
+applications call the :ref:`VIDIOC_S_INPUT <VIDIOC_G_INPUT>` and
+:ref:`VIDIOC_S_OUTPUT <VIDIOC_G_OUTPUT>` ioctls. Drivers must
+implement all the input ioctls when the device has one or more inputs,
+all the output ioctls when the device has one or more outputs.
+
+Example: Information about the current video input
+==================================================
+
+.. code-block:: c
+
+    struct v4l2_input input;

+VIDIOC_CREATE_BUFS - Create buffers for Memory Mapped or User Pointer or DMA Buffer I/O
+
+
+Synopsis
+========
+
+.. cpp:function:: int ioctl( int fd, int request, struct v4l2_create_buffers *argp )
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``request``
+    VIDIOC_CREATE_BUFS
+
+``argp``
+
+
+Description
+===========
+
+This ioctl is used to create buffers for :ref:`memory mapped <mmap>`
+or :ref:`user pointer <userp>` or :ref:`DMA buffer <dmabuf>` I/O. It
+can be used as an alternative or in addition to the
+:ref:`VIDIOC_REQBUFS` ioctl, when a tighter control
+over buffers is required. This ioctl can be called multiple times to
+create buffers of different sizes.
+
+To allocate the device buffers applications must initialize the relevant
+fields of the :ref:`struct v4l2_create_buffers <v4l2-create-buffers>` structure. The
+``count`` field must be set to the number of requested buffers, the
+``memory`` field specifies the requested I/O method and the ``reserved``
+array must be zeroed.
+
+The ``format`` field specifies the image format that the buffers must be
+able to handle. The application has to fill in this struct
+:ref:`v4l2_format <v4l2-format>`. Usually this will be done using the
+:ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` or
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctls to ensure that the
+requested format is supported by the driver. Based on the format's
+``type`` field the requested buffer size (for single-planar) or plane
+sizes (for multi-planar formats) will be used for the allocated buffers.
+The driver may return an error if the size(s) are not supported by the
+hardware (usually because they are too small).
+
+The buffers created by this ioctl will have as minimum size the size
+defined by the ``format.pix.sizeimage`` field (or the corresponding
+fields for other format types). Usually if the ``format.pix.sizeimage``
+field is less than the minimum required for the given format, then an
+error will be returned since drivers will typically not allow this. If
+it is larger, then the value will be used as-is. In other words, the
+driver may reject the requested size, but if it is accepted the driver
+will use it unchanged.
+
+When the ioctl is called with a pointer to this structure the driver
+will attempt to allocate up to the requested number of buffers and store
+the actual number allocated and the starting index in the ``count`` and
+the ``index`` fields respectively. On return ``count`` can be smaller
+than the number requested.

+Description
+===========
+
+Applications use this function to query the cropping limits, the pixel
+aspect of images and to calculate scale factors. They set the ``type``
+field of a v4l2_cropcap structure to the respective buffer (stream)
+type and call the :ref:`VIDIOC_CROPCAP` ioctl with a pointer to this
+structure. Drivers fill the rest of the structure. The results are
+constant except when switching the video standard. Remember this switch
+can occur implicit when switching the video input or output.
+
+Do not use the multiplanar buffer types. Use
+``V4L2_BUF_TYPE_VIDEO_CAPTURE`` instead of
+``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and use
+``V4L2_BUF_TYPE_VIDEO_OUTPUT`` instead of
+``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``.
+
+This ioctl must be implemented for video capture or output devices that
+support cropping and/or scaling and/or have non-square pixels, and for
+overlay devices.

+
+
+Arguments
+=========

+    File descriptor returned by :ref:`open() <func-open>`.
+
+``request``
+    VIDIOC_DBG_G_CHIP_INFO
+
+``argp``
+
+
+Description
+===========
+
+.. note::
+
+    This is an :ref:`experimental` interface and may
+    change in the future.
+
+For driver debugging purposes this ioctl allows test applications to
+query the driver about the chips present on the TV card. Regular
+applications must not use it. When you found a chip specific bug, please
+contact the linux-media mailing list
+(`https://linuxtv.org/lists.php <https://linuxtv.org/lists.php>`__)
+so it can be fixed.
+
+Additionally the Linux kernel must be compiled with the
+``CONFIG_VIDEO_ADV_DEBUG`` option to enable this ioctl.
+
+To query the driver applications must initialize the ``match.type`` and
+``match.addr`` or ``match.name`` fields of a struct
+:ref:`v4l2_dbg_chip_info <v4l2-dbg-chip-info>` and call
+:ref:`VIDIOC_DBG_G_CHIP_INFO` with a pointer to this structure. On success
+the driver stores information about the selected chip in the ``name``
+and ``flags`` fields.
+
+When ``match.type`` is ``V4L2_CHIP_MATCH_BRIDGE``, ``match.addr``
+selects the nth bridge 'chip' on the TV card. You can enumerate all
+chips by starting at zero and incrementing ``match.addr`` by one until
+:ref:`VIDIOC_DBG_G_CHIP_INFO` fails with an ``EINVAL`` error code. The number
+zero always selects the bridge chip itself, e. g. the chip connected to
+the PCI or USB bus. Non-zero numbers identify specific parts of the
+bridge chip such as an AC97 register block.
+
+When ``match.type`` is ``V4L2_CHIP_MATCH_SUBDEV``, ``match.addr``
+selects the nth sub-device. This allows you to enumerate over all
+sub-devices.
+
+On success, the ``name`` field will contain a chip name and the
+``flags`` field will contain ``V4L2_CHIP_FL_READABLE`` if the driver
+supports reading registers from the device or ``V4L2_CHIP_FL_WRITABLE``
+if the driver supports writing registers to the device.
+
+We recommended the v4l2-dbg utility over calling this ioctl directly. It
+is available from the LinuxTV v4l-dvb repository; see

+
+Description
+===========
+
+.. note::
+
+    This is an :ref:`experimental` interface and may
+    change in the future.
+
+For driver debugging purposes these ioctls allow test applications to
+access hardware registers directly. Regular applications must not use
+them.
+
+Since writing or even reading registers can jeopardize the system
+security, its stability and damage the hardware, both ioctls require
+superuser privileges. Additionally the Linux kernel must be compiled
+with the ``CONFIG_VIDEO_ADV_DEBUG`` option to enable these ioctls.
+
+To write a register applications must initialize all fields of a struct
+:ref:`v4l2_dbg_register <v4l2-dbg-register>` except for ``size`` and
+call ``VIDIOC_DBG_S_REGISTER`` with a pointer to this structure. The
+``match.type`` and ``match.addr`` or ``match.name`` fields select a chip
+on the TV card, the ``reg`` field specifies a register number and the
+``val`` field the value to be written into the register.
+
+To read a register applications must initialize the ``match.type``,
+``match.addr`` or ``match.name`` and ``reg`` fields, and call
+``VIDIOC_DBG_G_REGISTER`` with a pointer to this structure. On success
+the driver stores the register value in the ``val`` field and the size
+(in bytes) of the value in ``size``.
+
+When ``match.type`` is ``V4L2_CHIP_MATCH_BRIDGE``, ``match.addr``
+selects the nth non-sub-device chip on the TV card. The number zero
+always selects the host chip, e. g. the chip connected to the PCI or USB
+bus. You can find out which chips are present with the
+:ref:`VIDIOC_DBG_G_CHIP_INFO` ioctl.
+
+When ``match.type`` is ``V4L2_CHIP_MATCH_SUBDEV``, ``match.addr``
+selects the nth sub-device.
+
+These ioctls are optional, not all drivers may support them. However
+when a driver supports these ioctls it must also support
+:ref:`VIDIOC_DBG_G_CHIP_INFO`. Conversely
+it may support ``VIDIOC_DBG_G_CHIP_INFO`` but not these ioctls.
+
+``VIDIOC_DBG_G_REGISTER`` and ``VIDIOC_DBG_S_REGISTER`` were introduced
+in Linux 2.6.21, but their API was changed to the one described here in
+kernel 2.6.29.

+Description
+===========
+
+These ioctls control an audio/video (usually MPEG-) decoder.
+``VIDIOC_DECODER_CMD`` sends a command to the decoder,
+``VIDIOC_TRY_DECODER_CMD`` can be used to try a command without actually
+executing it. To send a command applications must initialize all fields
+of a struct :ref:`v4l2_decoder_cmd <v4l2-decoder-cmd>` and call
+``VIDIOC_DECODER_CMD`` or ``VIDIOC_TRY_DECODER_CMD`` with a pointer to
+this structure.
+
+The ``cmd`` field must contain the command code. Some commands use the
+``flags`` field for additional information.
+
+A :ref:`write() <func-write>` or :ref:`VIDIOC_STREAMON`
+call sends an implicit START command to the decoder if it has not been
+started yet.
+
+A :ref:`close() <func-close>` or :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
+call of a streaming file descriptor sends an implicit immediate STOP
+command to the decoder, and all buffered data is discarded.
+
+These ioctls are optional, not all drivers may support them. They were
+introduced in Linux 3.3.

+	  ``V4L2_DEC_CMD_STOP_TO_BLACK`` is set, then the decoder will set
+	  the picture to black after it stopped decoding. Otherwise the last
+	  image will repeat. mem2mem decoders will stop producing new frames
+	  altogether. They will send a ``V4L2_EVENT_EOS`` event when the
+	  last frame has been decoded and all frames are ready to be
+	  dequeued and will set the ``V4L2_BUF_FLAG_LAST`` buffer flag on
+	  the last buffer of the capture queue to indicate there will be no
+	  new buffers produced to dequeue. This buffer may be empty,
+	  indicated by the driver setting the ``bytesused`` field to 0. Once
+	  the ``V4L2_BUF_FLAG_LAST`` flag was set, the
+	  :ref:`VIDIOC_DQBUF <VIDIOC_QBUF>` ioctl will not block anymore,
+	  but return an ``EPIPE`` error code. If
+	  ``V4L2_DEC_CMD_STOP_IMMEDIATELY`` is set, then the decoder stops

+	  decoding until timestamp >= pts or until the last of the pending

+	  flag: if ``V4L2_DEC_CMD_PAUSE_TO_BLACK`` is set, then set the

+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set

+
+EINVAL
+    The ``cmd`` field is invalid.
+
+EPERM
+    The application sent a PAUSE or RESUME command when the decoder was
+    not running.

+    -  .. row 4
+
+       -  ``V4L2_EVENT_CTRL``
+
+       -  3
+
+       -  This event requires that the ``id`` matches the control ID from
+	  which you want to receive events. This event is triggered if the
+	  control's value changes, if a button control is pressed or if the
+	  control's flags change. This event has a struct
+	  :ref:`v4l2_event_ctrl <v4l2-event-ctrl>` associated with it.
+	  This struct contains much of the same information as struct
+	  :ref:`v4l2_queryctrl <v4l2-queryctrl>` and struct
+	  :ref:`v4l2_control <v4l2-control>`.
+

+	  :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` or
+	  :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`, then the
+	  event will *not* be sent to the file handle that called the ioctl
+	  function. This prevents nasty feedback loops. If you *do* want to
+	  get the event, then set the ``V4L2_EVENT_SUB_FL_ALLOW_FEEDBACK``
+	  flag.
+
+	  This event type will ensure that no information is lost when more
+	  events are raised than there is room internally. In that case the
+	  struct :ref:`v4l2_event_ctrl <v4l2-event-ctrl>` of the
+	  second-oldest event is kept, but the ``changes`` field of the
+	  second-oldest event is ORed with the ``changes`` field of the

+	  associated with it.
+
+	  If the hardware needs to be stopped in the case of a buffer
+	  underrun it might not be able to generate this event. In such
+	  cases the ``frame_sequence`` field in struct
+	  :ref:`v4l2_event_frame_sync <v4l2-event-frame-sync>` will not
+	  be incremented. This causes two consecutive frame sequence numbers
+	  to have n times frame interval in between them.

+
+       -  ``V4L2_EVENT_SOURCE_CHANGE``
+
+       -  5
+
+       -  This event is triggered when a source parameter change is detected
+	  during runtime by the video device. It can be a runtime resolution
+	  change triggered by a video decoder or the format change happening
+	  on an input connector. This event requires that the ``id`` matches
+	  the input index (when used with a video device node) or the pad
+	  index (when used with a subdevice node) from which you want to
+	  receive events.
+
+	  This event has a struct
+	  :ref:`v4l2_event_src_change <v4l2-event-src-change>`
+	  associated with it. The ``changes`` bitfield denotes what has
+	  changed for the subscribed pad. If multiple events occurred before
+	  application could dequeue them, then the changes will have the
+	  ORed value of all the events generated.

+Description
+===========
+
+To query the capabilities of the DV receiver/transmitter applications
+initialize the ``pad`` field to 0, zero the reserved array of struct
+:ref:`v4l2_dv_timings_cap <v4l2-dv-timings-cap>` and call the
+``VIDIOC_DV_TIMINGS_CAP`` ioctl on a video node and the driver will fill
+in the structure.
+
+.. note:: Drivers may return different values after
+   switching the video input or output.
+
+When implemented by the driver DV capabilities of subdevices can be
+queried by calling the ``VIDIOC_SUBDEV_DV_TIMINGS_CAP`` ioctl directly
+on a subdevice node. The capabilities are specific to inputs (for DV
+receivers) or outputs (for DV transmitters), applications must specify
+the desired pad number in the struct
+:ref:`v4l2_dv_timings_cap <v4l2-dv-timings-cap>` ``pad`` field and
+zero the ``reserved`` array. Attempts to query capabilities on a pad
+that doesn't support them will return an ``EINVAL`` error code.

+
+
+Description
+===========
+
+These ioctls control an audio/video (usually MPEG-) encoder.
+``VIDIOC_ENCODER_CMD`` sends a command to the encoder,
+``VIDIOC_TRY_ENCODER_CMD`` can be used to try a command without actually
+executing it.
+
+To send a command applications must initialize all fields of a struct
+:ref:`v4l2_encoder_cmd <v4l2-encoder-cmd>` and call
+``VIDIOC_ENCODER_CMD`` or ``VIDIOC_TRY_ENCODER_CMD`` with a pointer to
+this structure.
+
+The ``cmd`` field must contain the command code. The ``flags`` field is
+currently only used by the STOP command and contains one bit: If the
+``V4L2_ENC_CMD_STOP_AT_GOP_END`` flag is set, encoding will continue
+until the end of the current *Group Of Pictures*, otherwise it will stop
+immediately.
+
+A :ref:`read() <func-read>` or :ref:`VIDIOC_STREAMON <VIDIOC_STREAMON>`
+call sends an implicit START command to the encoder if it has not been
+started yet. After a STOP command, :ref:`read() <func-read>` calls will read
+the remaining data buffered by the driver. When the buffer is empty,
+:ref:`read() <func-read>` will return zero and the next :ref:`read() <func-read>`
+call will restart the encoder.
+
+A :ref:`close() <func-close>` or :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`
+call of a streaming file descriptor sends an implicit immediate STOP to
+the encoder, and all buffered data is discarded.
+
+These ioctls are optional, not all drivers may support them. They were
+introduced in Linux 2.6.21.

+
+While some DV receivers or transmitters support a wide range of timings,

+applications can enumerate a list of known supported timings. Call
+:ref:`VIDIOC_DV_TIMINGS_CAP` to check if it
+also supports other standards or even custom timings that are not in
+this list.
+
+To query the available timings, applications initialize the ``index``
+field, set the ``pad`` field to 0, zero the reserved array of struct
+:ref:`v4l2_enum_dv_timings <v4l2-enum-dv-timings>` and call the
+``VIDIOC_ENUM_DV_TIMINGS`` ioctl on a video node with a pointer to this
+structure. Drivers fill the rest of the structure or return an ``EINVAL``
+error code when the index is out of bounds. To enumerate all supported
+DV timings, applications shall begin at index zero, incrementing by one
+until the driver returns ``EINVAL``.
+
+.. note:: Drivers may enumerate a different set of DV timings after
+   switching the video input or output.
+
+When implemented by the driver DV timings of subdevices can be queried
+by calling the ``VIDIOC_SUBDEV_ENUM_DV_TIMINGS`` ioctl directly on a
+subdevice node. The DV timings are specific to inputs (for DV receivers)
+or outputs (for DV transmitters), applications must specify the desired
+pad number in the struct
+:ref:`v4l2_enum_dv_timings <v4l2-enum-dv-timings>` ``pad`` field.
+Attempts to enumerate timings on a pad that doesn't support them will

+    Pointer to a struct :ref:`v4l2_frmivalenum <v4l2-frmivalenum>`
+    structure that contains a pixel format and size and receives a frame
+    interval.
+
+
+Description
+===========
+
+This ioctl allows applications to enumerate all frame intervals that the
+device supports for the given pixel format and frame size.
+
+The supported pixel formats and frame sizes can be obtained by using the
+:ref:`VIDIOC_ENUM_FMT` and
+:ref:`VIDIOC_ENUM_FRAMESIZES` functions.
+
+The return value and the content of the ``v4l2_frmivalenum.type`` field
+depend on the type of frame intervals the device supports. Here are the
+semantics of the function for the different cases:
+
+-  **Discrete:** The function returns success if the given index value
+   (zero-based) is valid. The application should increase the index by
+   one for each call until ``EINVAL`` is returned. The
+   `v4l2_frmivalenum.type` field is set to
+   `V4L2_FRMIVAL_TYPE_DISCRETE` by the driver. Of the union only
+   the `discrete` member is valid.
+
+-  **Step-wise:** The function returns success if the given index value
+   is zero and ``EINVAL`` for any other index value. The
+   ``v4l2_frmivalenum.type`` field is set to
+   ``V4L2_FRMIVAL_TYPE_STEPWISE`` by the driver. Of the union only the
+   ``stepwise`` member is valid.
+
+-  **Continuous:** This is a special case of the step-wise type above.
+   The function returns success if the given index value is zero and
+   ``EINVAL`` for any other index value. The ``v4l2_frmivalenum.type``
+   field is set to ``V4L2_FRMIVAL_TYPE_CONTINUOUS`` by the driver. Of
+   the union only the ``stepwise`` member is valid and the ``step``
+   value is set to 1.
+
+When the application calls the function with index zero, it must check
+the ``type`` field to determine the type of frame interval enumeration
+the device supports. Only for the ``V4L2_FRMIVAL_TYPE_DISCRETE`` type
+does it make sense to increase the index value to receive more frame
+intervals.
+
+.. note:: The order in which the frame intervals are returned has no
+   special meaning. In particular does it not say anything about potential
+   default frame intervals.
+
+Applications can assume that the enumeration data does not change
+without any interaction from the application itself. This means that the
+enumeration data is consistent if the application does not perform any
+other ioctl calls while it runs the frame interval enumeration.
+
+.. note::
+
+   **Frame intervals and frame rates:** The V4L2 API uses frame
+   intervals instead of frame rates. Given the frame interval the frame
+   rate can be computed as follows:
+
+   ::
+
+       frame_rate = 1 / frame_interval

+Description
+===========
+
+To query the attributes of a video standard, especially a custom (driver
+defined) one, applications initialize the ``index`` field of struct
+:ref:`v4l2_standard <v4l2-standard>` and call the :ref:`VIDIOC_ENUMSTD`
+ioctl with a pointer to this structure. Drivers fill the rest of the
+structure or return an ``EINVAL`` error code when the index is out of
+bounds. To enumerate all standards applications shall begin at index
+zero, incrementing by one until the driver returns ``EINVAL``. Drivers may
+enumerate a different set of standards after switching the video input
+or output. [#f1]_

+VIDIOC_EXPBUF - Export a buffer as a DMABUF file descriptor.
+
+
+Synopsis
+========
+
+.. cpp:function:: int ioctl( int fd, int request, struct v4l2_exportbuffer *argp )
+
+
+Arguments
+=========
+
+``fd``
+    File descriptor returned by :ref:`open() <func-open>`.
+
+``request``
+    VIDIOC_EXPBUF
+
+``argp``
+
+
+Description
+===========
+
+This ioctl is an extension to the :ref:`memory mapping <mmap>` I/O
+method, therefore it is available only for ``V4L2_MEMORY_MMAP`` buffers.
+It can be used to export a buffer as a DMABUF file at any time after
+buffers have been allocated with the
+:ref:`VIDIOC_REQBUFS` ioctl.
+
+To export a buffer, applications fill struct
+:ref:`v4l2_exportbuffer <v4l2-exportbuffer>`. The ``type`` field is
+set to the same buffer type as was previously used with struct
+:ref:`v4l2_requestbuffers <v4l2-requestbuffers>` ``type``.
+Applications must also set the ``index`` field. Valid index numbers
+range from zero to the number of buffers allocated with
+:ref:`VIDIOC_REQBUFS` (struct
+:ref:`v4l2_requestbuffers <v4l2-requestbuffers>` ``count``) minus
+one. For the multi-planar API, applications set the ``plane`` field to
+the index of the plane to be exported. Valid planes range from zero to
+the maximal number of valid planes for the currently active format. For
+the single-planar API, applications must set ``plane`` to zero.
+Additional flags may be posted in the ``flags`` field. Refer to a manual
+for open() for details. Currently only O_CLOEXEC, O_RDONLY, O_WRONLY,
+and O_RDWR are supported. All other fields must be set to zero. In the
+case of multi-planar API, every plane is exported separately using
+multiple :ref:`VIDIOC_EXPBUF` calls.
+
+After calling :ref:`VIDIOC_EXPBUF` the ``fd`` field will be set by a
+driver. This is a DMABUF file descriptor. The application may pass it to
+other DMABUF-aware devices. Refer to :ref:`DMABUF importing <dmabuf>`
+for details about importing DMABUF files into V4L2 nodes. It is
+recommended to close a DMABUF file when it is no longer used to allow
+the associated memory to be reclaimed.

+
+
+Description
+===========
+
+To query the cropping rectangle size and position applications set the
+``type`` field of a :ref:`struct v4l2_crop <v4l2-crop>` structure to the
+respective buffer (stream) type and call the :ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` ioctl
+with a pointer to this structure. The driver fills the rest of the
+structure or returns the ``EINVAL`` error code if cropping is not supported.
+
+To change the cropping rectangle applications initialize the ``type``
+and struct :ref:`v4l2_rect <v4l2-rect>` substructure named ``c`` of a
+v4l2_crop structure and call the :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` ioctl with a pointer
+to this structure.
+
+Do not use the multiplanar buffer types. Use
+``V4L2_BUF_TYPE_VIDEO_CAPTURE`` instead of
+``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and use
+``V4L2_BUF_TYPE_VIDEO_OUTPUT`` instead of
+``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``.
+
+The driver first adjusts the requested dimensions against hardware
+limits, i. e. the bounds given by the capture/output window, and it
+rounds to the closest possible values of horizontal and vertical offset,
+width and height. In particular the driver must round the vertical
+offset of the cropping rectangle to frame lines modulo two, such that
+the field order cannot be confused.
+
+Second the driver adjusts the image size (the opposite rectangle of the
+scaling process, source or target depending on the data direction) to
+the closest size possible while maintaining the current horizontal and
+vertical scaling factor.
+
+Finally the driver programs the hardware with the actual cropping and
+image parameters. :ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` is a write-only ioctl, it does not
+return the actual parameters. To query them applications must call
+:ref:`VIDIOC_G_CROP <VIDIOC_G_CROP>` and :ref:`VIDIOC_G_FMT`. When the
+parameters are unsuitable the application may modify the cropping or
+image parameters and repeat the cycle until satisfactory parameters have
+been negotiated.
+
+When cropping is not supported then no parameters are changed and
+:ref:`VIDIOC_S_CROP <VIDIOC_G_CROP>` returns the ``EINVAL`` error code.

+

+
+
+Description
+===========
+
+These ioctls can be used to get or set an EDID associated with an input
+from a receiver or an output of a transmitter device. They can be used
+with subdevice nodes (/dev/v4l-subdevX) or with video nodes
+(/dev/videoX).
+
+When used with video nodes the ``pad`` field represents the input (for
+video capture devices) or output (for video output devices) index as is
+returned by :ref:`VIDIOC_ENUMINPUT` and
+:ref:`VIDIOC_ENUMOUTPUT` respectively. When used
+with subdevice nodes the ``pad`` field represents the input or output
+pad of the subdevice. If there is no EDID support for the given ``pad``
+value, then the ``EINVAL`` error code will be returned.
+
+To get the EDID data the application has to fill in the ``pad``,
+``start_block``, ``blocks`` and ``edid`` fields, zero the ``reserved``
+array and call :ref:`VIDIOC_G_EDID <VIDIOC_G_EDID>`. The current EDID from block
+``start_block`` and of size ``blocks`` will be placed in the memory
+``edid`` points to. The ``edid`` pointer must point to memory at least
+``blocks`` * 128 bytes large (the size of one block is 128 bytes).
+
+If there are fewer blocks than specified, then the driver will set
+``blocks`` to the actual number of blocks. If there are no EDID blocks
+available at all, then the error code ``ENODATA`` is set.
+
+If blocks have to be retrieved from the sink, then this call will block
+until they have been read.
+
+If ``start_block`` and ``blocks`` are both set to 0 when
+:ref:`VIDIOC_G_EDID <VIDIOC_G_EDID>` is called, then the driver will set ``blocks`` to the
+total number of available EDID blocks and it will return 0 without
+copying any data. This is an easy way to discover how many EDID blocks
+there are.
+
+.. note:: If there are no EDID blocks available at all, then
+   the driver will set ``blocks`` to 0 and it returns 0.
+
+To set the EDID blocks of a receiver the application has to fill in the
+``pad``, ``blocks`` and ``edid`` fields, set ``start_block`` to 0 and
+zero the ``reserved`` array. It is not possible to set part of an EDID,
+it is always all or nothing. Setting the EDID data is only valid for
+receivers as it makes no sense for a transmitter.
+
+The driver assumes that the full EDID is passed in. If there are more
+EDID blocks than the hardware can handle then the EDID is not written,
+but instead the error code ``E2BIG`` is set and ``blocks`` is set to the
+maximum that the hardware supports. If ``start_block`` is any value
+other than 0 then the error code ``EINVAL`` is set.
+
+To disable an EDID you set ``blocks`` to 0. Depending on the hardware
+this will drive the hotplug pin low and/or block the source from reading
+the EDID data in some way. In any case, the end result is the same: the
+EDID is no longer available.

+VIDIOC_G_ENC_INDEX - Get meta data about a compressed video stream

+``argp``
+
+
+Description
+===========
+
+The :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` ioctl provides meta data about a compressed
+video stream the same or another application currently reads from the
+driver, which is useful for random access into the stream without
+decoding it.
+
+To read the data applications must call :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` with a
+pointer to a struct :ref:`v4l2_enc_idx <v4l2-enc-idx>`. On success
+the driver fills the ``entry`` array, stores the number of elements
+written in the ``entries`` field, and initializes the ``entries_cap``
+field.
+
+Each element of the ``entry`` array contains meta data about one
+picture. A :ref:`VIDIOC_G_ENC_INDEX <VIDIOC_G_ENC_INDEX>` call reads up to
+``V4L2_ENC_IDX_ENTRIES`` entries from a driver buffer, which can hold up
+to ``entries_cap`` entries. This number can be lower or higher than
+``V4L2_ENC_IDX_ENTRIES``, but not zero. When the application fails to
+read the meta data in time the oldest entries will be lost. When the
+buffer is empty or no capturing/encoding is in progress, ``entries``
+will be zero.
+
+Currently this ioctl is only defined for MPEG-2 program streams and
+video elementary streams.

+    File descriptor returned by :ref:`open() <func-open>`.

+    VIDIOC_G_EXT_CTRLS, VIDIOC_S_EXT_CTRLS,

+
+``argp``
+
+
+Description
+===========
+
+These ioctls allow the caller to get or set multiple controls
+atomically. Control IDs are grouped into control classes (see
+:ref:`ctrl-class`) and all controls in the control array must belong
+to the same control class.
+
+Applications must always fill in the ``count``, ``which``, ``controls``
+and ``reserved`` fields of struct
+:ref:`v4l2_ext_controls <v4l2-ext-controls>`, and initialize the
+struct :ref:`v4l2_ext_control <v4l2-ext-control>` array pointed to
+by the ``controls`` fields.
+
+To get the current value of a set of controls applications initialize
+the ``id``, ``size`` and ``reserved2`` fields of each struct
+:ref:`v4l2_ext_control <v4l2-ext-control>` and call the
+:ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. String controls controls must also set the
+``string`` field. Controls of compound types
+(``V4L2_CTRL_FLAG_HAS_PAYLOAD`` is set) must set the ``ptr`` field.
+
+If the ``size`` is too small to receive the control result (only
+relevant for pointer-type controls like strings), then the driver will
+set ``size`` to a valid value and return an ``ENOSPC`` error code. You
+should re-allocate the memory to this new size and try again. For the
+string type it is possible that the same issue occurs again if the
+string has grown in the meantime. It is recommended to call
+:ref:`VIDIOC_QUERYCTRL` first and use
+``maximum``\ +1 as the new ``size`` value. It is guaranteed that that is
+sufficient memory.
+
+N-dimensional arrays are set and retrieved row-by-row. You cannot set a
+partial array, all elements have to be set or retrieved. The total size
+is calculated as ``elems`` * ``elem_size``. These values can be obtained
+by calling :ref:`VIDIOC_QUERY_EXT_CTRL <VIDIOC_QUERYCTRL>`.
+
+To change the value of a set of controls applications initialize the
+``id``, ``size``, ``reserved2`` and ``value/value64/string/ptr`` fields
+of each struct :ref:`v4l2_ext_control <v4l2-ext-control>` and call
+the :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. The controls will only be set if *all*
+control values are valid.
+
+To check if a set of controls have correct values applications
+initialize the ``id``, ``size``, ``reserved2`` and
+``value/value64/string/ptr`` fields of each struct
+:ref:`v4l2_ext_control <v4l2-ext-control>` and call the
+:ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` ioctl. It is up to the driver whether wrong
+values are automatically adjusted to a valid value or if an error is
+returned.
+
+When the ``id`` or ``which`` is invalid drivers return an ``EINVAL`` error
+code. When the value is out of bounds drivers can choose to take the
+closest valid value or return an ``ERANGE`` error code, whatever seems more
+appropriate. In the first case the new value is set in struct
+:ref:`v4l2_ext_control <v4l2-ext-control>`. If the new control value
+is inappropriate (e.g. the given menu index is not supported by the menu
+control), then this will also result in an ``EINVAL`` error code error.
+
+The driver will only set/get these controls if all control values are
+correct. This prevents the situation where only some of the controls
+were set/get. Only low-level errors (e. g. a failed i2c command) can
+still cause this situation.

+	  support this can be tested by setting ``ctrl_class`` to 0 and
+	  calling :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` with a ``count`` of 0. If that

+
+	  .. note:: You can only get the default value of the control,
+	     you cannot set or try it.
+
+	  For backwards compatibility you can also use a control class here
+	  (see :ref:`ctrl-class`). In that case all controls have to
+	  belong to that control class. This usage is deprecated, instead
+	  just use ``V4L2_CTRL_WHICH_CUR_VAL``. There are some very old
+	  drivers that do not yet support ``V4L2_CTRL_WHICH_CUR_VAL`` and
+	  that require a control class here. You can test for such drivers
+	  by setting ctrl_class to ``V4L2_CTRL_WHICH_CUR_VAL`` and calling
+	  VIDIOC_TRY_EXT_CTRLS with a count of 0. If that fails, then the
+	  driver does not support ``V4L2_CTRL_WHICH_CUR_VAL``.
+
+    -  .. row 4
+
+       -  __u32
+
+       -  ``count``
+
+       -  The number of controls in the controls array. May also be zero.
+
+    -  .. row 5
+
+       -  __u32
+
+       -  ``error_idx``
+
+       -  Set by the driver in case of an error. If the error is associated
+	  with a particular control, then ``error_idx`` is set to the index
+	  of that control. If the error is not related to a specific
+	  control, or the validation step failed (see below), then
+	  ``error_idx`` is set to ``count``. The value is undefined if the
+	  ioctl returned 0 (success).
+
+	  Before controls are read from/written to hardware a validation
+	  step takes place: this checks if all controls in the list are
+	  valid controls, if no attempt is made to write to a read-only
+	  control or read from a write-only control, and any other up-front
+	  checks that can be done without accessing the hardware. The exact
+	  validations done during this step are driver dependent since some
+	  checks might require hardware access for some devices, thus making
+	  it impossible to do those checks up-front. However, drivers should
+	  make a best-effort to do as many up-front checks as possible.
+
+	  This check is done to avoid leaving the hardware in an
+	  inconsistent state due to easy-to-avoid problems. But it leads to
+	  another problem: the application needs to know whether an error
+	  came from the validation step (meaning that the hardware was not
+	  touched) or from an error during the actual reading from/writing
+	  to hardware.
+
+	  The, in hindsight quite poor, solution for that is to set
+	  ``error_idx`` to ``count`` if the validation failed. This has the
+	  unfortunate side-effect that it is not possible to see which
+	  control failed the validation. If the validation was successful
+	  and the error happened while accessing the hardware, then
+	  ``error_idx`` is less than ``count`` and only the controls up to
+	  ``error_idx-1`` were read or written correctly, and the state of
+	  the remaining controls is undefined.
+
+	  Since :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` does not access hardware there is
+	  also no need to handle the validation step in this special way, so
+	  ``error_idx`` will just be set to the control that failed the
+	  validation step instead of to ``count``. This means that if
+	  :ref:`VIDIOC_S_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` fails with ``error_idx`` set to ``count``,
+	  then you can call :ref:`VIDIOC_TRY_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>` to try to discover the
+	  actual control that failed the validation step. Unfortunately,
+	  there is no ``TRY`` equivalent for :ref:`VIDIOC_G_EXT_CTRLS <VIDIOC_G_EXT_CTRLS>`.

+
+
+Description
+===========
+
+Applications can use the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` and :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` ioctl
+to get and set the framebuffer parameters for a
+:ref:`Video Overlay <overlay>` or :ref:`Video Output Overlay <osd>`
+(OSD). The type of overlay is implied by the device type (capture or
+output device) and can be determined with the
+:ref:`VIDIOC_QUERYCAP` ioctl. One ``/dev/videoN``
+device must not support both kinds of overlay.
+
+The V4L2 API distinguishes destructive and non-destructive overlays. A
+destructive overlay copies captured video images into the video memory
+of a graphics card. A non-destructive overlay blends video images into a
+VGA signal or graphics into a video signal. *Video Output Overlays* are
+always non-destructive.
+
+To get the current parameters applications call the :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
+ioctl with a pointer to a :ref:`struct v4l2_framebuffer <v4l2-framebuffer>`
+structure. The driver fills all fields of the structure or returns an
+EINVAL error code when overlays are not supported.
+
+To set the parameters for a *Video Output Overlay*, applications must
+initialize the ``flags`` field of a struct
+:ref:`struct v4l2_framebuffer <v4l2-framebuffer>`. Since the framebuffer is
+implemented on the TV card all other parameters are determined by the
+driver. When an application calls :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>` with a pointer to
+this structure, the driver prepares for the overlay and returns the
+framebuffer parameters as :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>` does, or it returns an error
+code.
+
+To set the parameters for a *non-destructive Video Overlay*,
+applications must initialize the ``flags`` field, the ``fmt``
+substructure, and call :ref:`VIDIOC_S_FBUF <VIDIOC_G_FBUF>`. Again the driver prepares for
+the overlay and returns the framebuffer parameters as :ref:`VIDIOC_G_FBUF <VIDIOC_G_FBUF>`
+does, or it returns an error code.
+
+For a *destructive Video Overlay* applications must additionally provide
+a ``base`` address. Setting up a DMA to a random memory location can
+jeopardize the system security, its stability or even damage the
+hardware, therefore only the superuser can set the parameters for a
+destructive video overlay.

+
+
+Description
+===========
+
+These ioctls are used to negotiate the format of data (typically image
+format) exchanged between driver and application.
+
+To query the current parameters applications set the ``type`` field of a
+struct :ref:`struct v4l2_format <v4l2-format>` to the respective buffer (stream)
+type. For example video capture devices use
+``V4L2_BUF_TYPE_VIDEO_CAPTURE`` or
+``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE``. When the application calls the
+:ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` ioctl with a pointer to this structure the driver fills
+the respective member of the ``fmt`` union. In case of video capture
+devices that is either the struct
+:ref:`v4l2_pix_format <v4l2-pix-format>` ``pix`` or the struct
+:ref:`v4l2_pix_format_mplane <v4l2-pix-format-mplane>` ``pix_mp``
+member. When the requested buffer type is not supported drivers return
+an ``EINVAL`` error code.
+
+To change the current format parameters applications initialize the
+``type`` field and all fields of the respective ``fmt`` union member.
+For details see the documentation of the various devices types in
+:ref:`devices`. Good practice is to query the current parameters
+first, and to modify only those parameters not suitable for the
+application. When the application calls the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl with
+a pointer to a :ref:`struct v4l2_format <v4l2-format>` structure the driver
+checks and adjusts the parameters against hardware abilities. Drivers
+should not return an error code unless the ``type`` field is invalid,
+this is a mechanism to fathom device capabilities and to approach
+parameters acceptable for both the application and driver. On success
+the driver may program the hardware, allocate resources and generally
+prepare for data exchange. Finally the :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` ioctl returns
+the current format parameters as :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` does. Very simple,
+inflexible devices may even ignore all input and always return the
+default parameters. However all V4L2 devices exchanging data with the
+application must implement the :ref:`VIDIOC_G_FMT <VIDIOC_G_FMT>` and :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>`
+ioctl. When the requested buffer type is not supported drivers return an
+EINVAL error code on a :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` attempt. When I/O is already in
+progress or the resource is not available for other reasons drivers
+return the ``EBUSY`` error code.
+
+The :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` ioctl is equivalent to :ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` with one
+exception: it does not change driver state. It can also be called at any
+time, never returning ``EBUSY``. This function is provided to negotiate
+parameters, to learn about hardware limitations, without disabling I/O
+or possibly time consuming hardware preparations. Although strongly
+recommended drivers are not required to implement this ioctl.
+
+The format as returned by :ref:`VIDIOC_TRY_FMT <VIDIOC_G_FMT>` must be identical to what
+:ref:`VIDIOC_S_FMT <VIDIOC_G_FMT>` returns for the same input or output.

+
+Ronald Bultje elaborates:
+
+APP is some application-specific information. The application can set it
+itself, and it'll be stored in the JPEG-encoded fields (eg; interlacing
+information for in an AVI or so). COM is the same, but it's comments,
+like 'encoded by me' or so.
+
+jpeg_markers describes whether the huffman tables, quantization tables
+and the restart interval information (all JPEG-specific stuff) should be
+stored in the JPEG-encoded fields. These define how the JPEG field is
+encoded. If you omit them, applications assume you've used standard
+encoding. You usually do want to add them.

+Description
+===========
+
+To query the attributes of a modulator applications initialize the
+``index`` field and zero out the ``reserved`` array of a struct
+:ref:`v4l2_modulator <v4l2-modulator>` and call the
+:ref:`VIDIOC_G_MODULATOR <VIDIOC_G_MODULATOR>` ioctl with a pointer to this structure. Drivers
+fill the rest of the structure or return an ``EINVAL`` error code when the
+index is out of bounds. To enumerate all modulators applications shall
+begin at index zero, incrementing by one until the driver returns
+EINVAL.
+
+Modulators have two writable properties, an audio modulation set and the
+radio frequency. To change the modulated audio subprograms, applications
+initialize the ``index`` and ``txsubchans`` fields and the ``reserved``
+array and call the :ref:`VIDIOC_S_MODULATOR <VIDIOC_G_MODULATOR>` ioctl. Drivers may choose a
+different audio modulation if the request cannot be satisfied. However
+this is a write-only ioctl, it does not return the actual audio
+modulation selected.
+
+:ref:`SDR <sdr>` specific modulator types are ``V4L2_TUNER_SDR`` and
+``V4L2_TUNER_RF``. For SDR devices ``txsubchans`` field must be
+initialized to zero. The term 'modulator' means SDR transmitter in this
+context.
+
+To change the radio frequency the

+
+The current video standard determines a nominal number of frames per

+	     motion capture.
+
+	  -  The driver may support fewer pixel formats than motion capture
+	     (eg; true color).
+
+	  -  The driver may capture and arithmetically combine multiple
+	     successive fields or frames to remove color edge artifacts and
+	     reduce the noise in the video data.
+
+	  -  The driver may capture images in slices like a scanner in order
+	     to handle larger format images than would otherwise be
+	     possible.
+
+	  -  An image capture operation may be significantly slower than
+	     motion capture.
+
+	  -  Moving objects in the image might have excessive motion blur.
+
+	  -  Capture might only work through the :ref:`read() <func-read>` call.

+
+
+Description
+===========
+
+The ioctls are used to query and configure selection rectangles.
+
+To query the cropping (composing) rectangle set struct
+:ref:`v4l2_selection <v4l2-selection>` ``type`` field to the
+respective buffer type. Do not use the multiplanar buffer types. Use
+``V4L2_BUF_TYPE_VIDEO_CAPTURE`` instead of
+``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE`` and use
+``V4L2_BUF_TYPE_VIDEO_OUTPUT`` instead of
+``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``. The next step is setting the
+value of struct :ref:`v4l2_selection <v4l2-selection>` ``target``
+field to ``V4L2_SEL_TGT_CROP`` (``V4L2_SEL_TGT_COMPOSE``). Please refer
+to table :ref:`v4l2-selections-common` or :ref:`selection-api` for
+additional targets. The ``flags`` and ``reserved`` fields of struct
+:ref:`v4l2_selection <v4l2-selection>` are ignored and they must be
+filled with zeros. The driver fills the rest of the structure or returns
+EINVAL error code if incorrect buffer type or target was used. If
+cropping (composing) is not supported then the active rectangle is not
+mutable and it is always equal to the bounds rectangle. Finally, the
+struct :ref:`v4l2_rect <v4l2-rect>` ``r`` rectangle is filled with
+the current cropping (composing) coordinates. The coordinates are
+expressed in driver-dependent units. The only exception are rectangles
+for images in raw formats, whose coordinates are always expressed in
+pixels.
+
+To change the cropping (composing) rectangle set the struct
+:ref:`v4l2_selection <v4l2-selection>` ``type`` field to the
+respective buffer type. Do not use multiplanar buffers. Use
+``V4L2_BUF_TYPE_VIDEO_CAPTURE`` instead of
+``V4L2_BUF_TYPE_VIDEO_CAPTURE_MPLANE``. Use
+``V4L2_BUF_TYPE_VIDEO_OUTPUT`` instead of
+``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``. The next step is setting the
+value of struct :ref:`v4l2_selection <v4l2-selection>` ``target`` to
+``V4L2_SEL_TGT_CROP`` (``V4L2_SEL_TGT_COMPOSE``). Please refer to table
+:ref:`v4l2-selections-common` or :ref:`selection-api` for additional
+targets. The struct :ref:`v4l2_rect <v4l2-rect>` ``r`` rectangle need
+to be set to the desired active area. Field struct
+:ref:`v4l2_selection <v4l2-selection>` ``reserved`` is ignored and
+must be filled with zeros. The driver may adjust coordinates of the
+requested rectangle. An application may introduce constraints to control
+rounding behaviour. The struct :ref:`v4l2_selection <v4l2-selection>`
+``flags`` field must be set to one of the following:
+
+-  ``0`` - The driver can adjust the rectangle size freely and shall
+   choose a crop/compose rectangle as close as possible to the requested
+   one.
+
+-  ``V4L2_SEL_FLAG_GE`` - The driver is not allowed to shrink the
+   rectangle. The original rectangle must lay inside the adjusted one.
+
+-  ``V4L2_SEL_FLAG_LE`` - The driver is not allowed to enlarge the
+   rectangle. The adjusted rectangle must lay inside the original one.
+
+-  ``V4L2_SEL_FLAG_GE | V4L2_SEL_FLAG_LE`` - The driver must choose the
+   size exactly the same as in the requested rectangle.
+
+Please refer to :ref:`sel-const-adjust`.
+
+The driver may have to adjusts the requested dimensions against hardware
+limits and other parts as the pipeline, i.e. the bounds given by the
+capture/output window or TV display. The closest possible values of
+horizontal and vertical offset and sizes are chosen according to
+following priority:
+
+1. Satisfy constraints from struct
+   :ref:`v4l2_selection <v4l2-selection>` ``flags``.
+
+2. Adjust width, height, left, and top to hardware limits and
+   alignments.
+
+3. Keep center of adjusted rectangle as close as possible to the
+   original one.
+
+4. Keep width and height as close as possible to original ones.
+
+5. Keep horizontal and vertical offset as close as possible to original
+   ones.
+
+On success the struct :ref:`v4l2_rect <v4l2-rect>` ``r`` field
+contains the adjusted rectangle. When the parameters are unsuitable the
+application may modify the cropping (composing) or image parameters and
+repeat the cycle until satisfactory parameters have been negotiated. If
+constraints flags have to be violated at then ``ERANGE`` is returned. The
+error indicates that *there exist no rectangle* that satisfies the
+constraints.

+
+
+Description
+===========
+
+To query the attributes of a tuner applications initialize the ``index``
+field and zero out the ``reserved`` array of a struct
+:ref:`v4l2_tuner <v4l2-tuner>` and call the ``VIDIOC_G_TUNER`` ioctl
+with a pointer to this structure. Drivers fill the rest of the structure
+or return an ``EINVAL`` error code when the index is out of bounds. To
+enumerate all tuners applications shall begin at index zero,
+incrementing by one until the driver returns ``EINVAL``.
+
+Tuners have two writable properties, the audio mode and the radio
+frequency. To change the audio mode, applications initialize the
+``index``, ``audmode`` and ``reserved`` fields and call the
+``VIDIOC_S_TUNER`` ioctl. This will *not* change the current tuner,
+which is determined by the current video input. Drivers may choose a
+different audio mode if the requested mode is invalid or unsupported.
+Since this is a write-only ioctl, it does not return the actually
+selected audio mode.
+
+:ref:`SDR <sdr>` specific tuner types are ``V4L2_TUNER_SDR`` and
+``V4L2_TUNER_RF``. For SDR devices ``audmode`` field must be initialized
+to zero. The term 'tuner' means SDR receiver in this context.
+
+To change the radio frequency the
+:ref:`VIDIOC_S_FREQUENCY <VIDIOC_G_FREQUENCY>` ioctl is available.

+Description
+===========
+
+As the video/audio devices become more complicated it becomes harder to
+debug problems. When this ioctl is called the driver will output the

+dealing with problems like no sound, no video and incorrectly tuned
+channels. Also many modern devices autodetect video and audio standards
+and this ioctl will report what the device thinks what the standard is.
+Mismatches may give an indication where the problem is.
+
+This ioctl is optional and not all drivers support it. It was introduced
+in Linux 2.6.15.

+Synopsis

+

+Arguments

+
+``fd``

+

+    VIDIOC_QBUF, VIDIOC_DQBUF
+
+``argp``
+
+
+Description
+===========
+
+Applications call the ``VIDIOC_QBUF`` ioctl to enqueue an empty
+(capturing) or filled (output) buffer in the driver's incoming queue.
+The semantics depend on the selected I/O method.
+
+To enqueue a buffer applications set the ``type`` field of a struct
+:ref:`v4l2_buffer <v4l2-buffer>` to the same buffer type as was
+previously used with struct :ref:`v4l2_format <v4l2-format>` ``type``
+and struct :ref:`v4l2_requestbuffers <v4l2-requestbuffers>` ``type``.
+Applications must also set the ``index`` field. Valid index numbers
+range from zero to the number of buffers allocated with
+:ref:`VIDIOC_REQBUFS` (struct
+:ref:`v4l2_requestbuffers <v4l2-requestbuffers>` ``count``) minus
+one. The contents of the struct :ref:`struct v4l2_buffer <v4l2-buffer>` returned
+by a :ref:`VIDIOC_QUERYBUF` ioctl will do as well.
+When the buffer is intended for output (``type`` is
+``V4L2_BUF_TYPE_VIDEO_OUTPUT``, ``V4L2_BUF_TYPE_VIDEO_OUTPUT_MPLANE``,
+or ``V4L2_BUF_TYPE_VBI_OUTPUT``) applications must also initialize the
+``bytesused``, ``field`` and ``timestamp`` fields, see :ref:`buffer`
+for details. Applications must also set ``flags`` to 0. The
+``reserved2`` and ``reserved`` fields must be set to 0. When using the
+:ref:`multi-planar API <planar-apis>`, the ``m.planes`` field must
+contain a userspace pointer to a filled-in array of struct
+:ref:`v4l2_plane <v4l2-plane>` and the ``length`` field must be set
+to the number of elements in that array.
+
+To enqueue a :ref:`memory mapped <mmap>` buffer applications set the
+``memory`` field to ``V4L2_MEMORY_MMAP``. When ``VIDIOC_QBUF`` is called
+with a pointer to this structure the driver sets the
+``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_QUEUED`` flags and clears
+the ``V4L2_BUF_FLAG_DONE`` flag in the ``flags`` field, or it returns an
+EINVAL error code.
+
+To enqueue a :ref:`user pointer <userp>` buffer applications set the
+``memory`` field to ``V4L2_MEMORY_USERPTR``, the ``m.userptr`` field to
+the address of the buffer and ``length`` to its size. When the
+multi-planar API is used, ``m.userptr`` and ``length`` members of the
+passed array of struct :ref:`v4l2_plane <v4l2-plane>` have to be used
+instead. When ``VIDIOC_QBUF`` is called with a pointer to this structure
+the driver sets the ``V4L2_BUF_FLAG_QUEUED`` flag and clears the
+``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_DONE`` flags in the
+``flags`` field, or it returns an error code. This ioctl locks the
+memory pages of the buffer in physical memory, they cannot be swapped
+out to disk. Buffers remain locked until dequeued, until the
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or
+:ref:`VIDIOC_REQBUFS` ioctl is called, or until the
+device is closed.
+
+To enqueue a :ref:`DMABUF <dmabuf>` buffer applications set the
+``memory`` field to ``V4L2_MEMORY_DMABUF`` and the ``m.fd`` field to a
+file descriptor associated with a DMABUF buffer. When the multi-planar
+API is used the ``m.fd`` fields of the passed array of struct
+:ref:`v4l2_plane <v4l2-plane>` have to be used instead. When
+``VIDIOC_QBUF`` is called with a pointer to this structure the driver
+sets the ``V4L2_BUF_FLAG_QUEUED`` flag and clears the
+``V4L2_BUF_FLAG_MAPPED`` and ``V4L2_BUF_FLAG_DONE`` flags in the
+``flags`` field, or it returns an error code. This ioctl locks the
+buffer. Locking a buffer means passing it to a driver for a hardware
+access (usually DMA). If an application accesses (reads/writes) a locked
+buffer then the result is undefined. Buffers remain locked until
+dequeued, until the :ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>` or
+:ref:`VIDIOC_REQBUFS` ioctl is called, or until the
+device is closed.
+
+Applications call the ``VIDIOC_DQBUF`` ioctl to dequeue a filled
+(capturing) or displayed (output) buffer from the driver's outgoing
+queue. They just set the ``type``, ``memory`` and ``reserved`` fields of
+a struct :ref:`v4l2_buffer <v4l2-buffer>` as above, when
+``VIDIOC_DQBUF`` is called with a pointer to this structure the driver
+fills the remaining fields or returns an error code. The driver may also
+set ``V4L2_BUF_FLAG_ERROR`` in the ``flags`` field. It indicates a
+non-critical (recoverable) streaming error. In such case the application
+may continue as normal, but should be aware that data in the dequeued
+buffer might be corrupted. When using the multi-planar API, the planes
+array must be passed in as well.
+
+By default ``VIDIOC_DQBUF`` blocks when no buffer is in the outgoing
+queue. When the ``O_NONBLOCK`` flag was given to the
+:ref:`open() <func-open>` function, ``VIDIOC_DQBUF`` returns
+immediately with an ``EAGAIN`` error code when no buffer is available.
+
+The :ref:`struct v4l2_buffer <v4l2-buffer>` structure is specified in
+:ref:`buffer`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EAGAIN
+    Non-blocking I/O has been selected using ``O_NONBLOCK`` and no
+    buffer was in the outgoing queue.
+
+EINVAL
+    The buffer ``type`` is not supported, or the ``index`` is out of
+    bounds, or no buffers have been allocated yet, or the ``userptr`` or
+    ``length`` are invalid.
+
+EIO
+    ``VIDIOC_DQBUF`` failed due to an internal error. Can also indicate
+    temporary problems like signal loss.
+
+    .. note:: The driver might dequeue an (empty) buffer despite returning
+       an error, or even stop capturing. Reusing such buffer may be unsafe
+       though and its details (e.g. ``index``) may not be returned either.
+       It is recommended that drivers indicate recoverable errors by setting
+       the ``V4L2_BUF_FLAG_ERROR`` and returning 0 instead. In that case the
+       application should be able to safely reuse the buffer and continue
+       streaming.
+
+EPIPE
+    ``VIDIOC_DQBUF`` returns this on an empty capture queue for mem2mem
+    codecs if a buffer with the ``V4L2_BUF_FLAG_LAST`` was already
+    dequeued and no new buffers are expected to become available.

+
+
+Description
+===========
+
+The hardware may be able to detect the current DV timings automatically,
+similar to sensing the video standard. To do so, applications call
+:ref:`VIDIOC_QUERY_DV_TIMINGS` with a pointer to a struct
+:ref:`v4l2_dv_timings <v4l2-dv-timings>`. Once the hardware detects
+the timings, it will fill in the timings structure.
+
+.. note:: Drivers shall *not* switch timings automatically if new
+   timings are detected. Instead, drivers should send the
+   ``V4L2_EVENT_SOURCE_CHANGE`` event (if they support this) and expect
+   that userspace will take action by calling :ref:`VIDIOC_QUERY_DV_TIMINGS`.
+   The reason is that new timings usually mean different buffer sizes as
+   well, and you cannot change buffer sizes on the fly. In general,
+   applications that receive the Source Change event will have to call
+   :ref:`VIDIOC_QUERY_DV_TIMINGS`, and if the detected timings are valid they
+   will have to stop streaming, set the new timings, allocate new buffers
+   and start streaming again.
+
+If the timings could not be detected because there was no signal, then

+
+
+Description
+===========
+
+This ioctl is part of the :ref:`streaming <mmap>` I/O method. It can
+be used to query the status of a buffer at any time after buffers have
+been allocated with the :ref:`VIDIOC_REQBUFS` ioctl.
+
+Applications set the ``type`` field of a struct
+:ref:`v4l2_buffer <v4l2-buffer>` to the same buffer type as was
+previously used with struct :ref:`v4l2_format <v4l2-format>` ``type``
+and struct :ref:`v4l2_requestbuffers <v4l2-requestbuffers>` ``type``,
+and the ``index`` field. Valid index numbers range from zero to the
+number of buffers allocated with
+:ref:`VIDIOC_REQBUFS` (struct
+:ref:`v4l2_requestbuffers <v4l2-requestbuffers>` ``count``) minus
+one. The ``reserved`` and ``reserved2`` fields must be set to 0. When
+using the :ref:`multi-planar API <planar-apis>`, the ``m.planes``
+field must contain a userspace pointer to an array of struct
+:ref:`v4l2_plane <v4l2-plane>` and the ``length`` field has to be set
+to the number of elements in that array. After calling
+:ref:`VIDIOC_QUERYBUF` with a pointer to this structure drivers return an
+error code or fill the rest of the structure.
+
+In the ``flags`` field the ``V4L2_BUF_FLAG_MAPPED``,
+``V4L2_BUF_FLAG_PREPARED``, ``V4L2_BUF_FLAG_QUEUED`` and
+``V4L2_BUF_FLAG_DONE`` flags will be valid. The ``memory`` field will be
+set to the current I/O method. For the single-planar API, the
+``m.offset`` contains the offset of the buffer from the start of the
+device memory, the ``length`` field its size. For the multi-planar API,
+fields ``m.mem_offset`` and ``length`` in the ``m.planes`` array
+elements will be used instead and the ``length`` field of struct
+:ref:`v4l2_buffer <v4l2-buffer>` is set to the number of filled-in
+array elements. The driver may or may not set the remaining fields and
+flags, they are meaningless in this context.
+
+The :ref:`struct v4l2_buffer <v4l2-buffer>` structure is specified in
+:ref:`buffer`.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+EINVAL
+    The buffer ``type`` is not supported, or the ``index`` is out of
+    bounds.

+
+
+Description
+===========
+
+All V4L2 devices support the ``VIDIOC_QUERYCAP`` ioctl. It is used to
+identify kernel devices compatible with this specification and to obtain
+information about driver and hardware capabilities. The ioctl takes a
+pointer to a struct :ref:`v4l2_capability <v4l2-capability>` which is
+filled by the driver. When the driver is not compatible with this
+specification the ioctl returns an ``EINVAL`` error code.

+
+       -  __u8
+
+       -  ``driver``\ [16]
+
+       -  Name of the driver, a unique NUL-terminated ASCII string. For
+	  example: "bttv". Driver specific applications can use this
+	  information to verify the driver identity. It is also useful to
+	  work around known bugs, or to identify drivers in error reports.
+
+	  Storing strings in fixed sized arrays is bad practice but
+	  unavoidable here. Drivers and applications should take precautions
+	  to never read or write beyond the end of the array and to make
+	  sure the strings are properly NUL-terminated.

+    -  .. row 2

+       -  __u8

+       -  ``card``\ [32]
+
+       -  Name of the device, a NUL-terminated UTF-8 string. For example:
+	  "Yoyodyne TV/FM". One driver may support different brands or
+	  models of video hardware. This information is intended for users,
+	  for example in a menu of available devices. Since multiple TV
+	  cards of the same brand may be installed which are supported by
+	  the same driver, this name should be combined with the character
+	  device file name (e. g. ``/dev/video2``) or the ``bus_info``
+	  string to avoid ambiguities.

+    -  .. row 3
+
+       -  __u8
+
+       -  ``bus_info``\ [32]
+
+       -  Location of the device in the system, a NUL-terminated ASCII
+	  string. For example: "PCI:0000:05:06.0". This information is
+	  intended for users, to distinguish multiple identical devices. If
+	  no such information is available the field must simply count the
+	  devices controlled by the driver ("platform:vivi-000"). The
+	  bus_info must start with "PCI:" for PCI boards, "PCIe:" for PCI
+	  Express boards, "usb-" for USB devices, "I2C:" for i2c devices,
+	  "ISA:" for ISA devices, "parport" for parallel port devices and
+	  "platform:" for platform devices.

+
+	  Starting with kernel 3.1, the version reported is provided by the
+	  V4L2 subsystem following the kernel numbering scheme. However, it
+	  may not always return the same version as the kernel if, for
+	  example, a stable or distribution-modified kernel uses the V4L2
+	  stack from a newer kernel.
+
+	  The version number is formatted using the ``KERNEL_VERSION()``

+
+       -  ``capabilities``
+
+       -  Available capabilities of the physical device as a whole, see
+	  :ref:`device-capabilities`. The same physical device can export
+	  multiple devices in /dev (e.g. /dev/videoX, /dev/vbiY and
+	  /dev/radioZ). The ``capabilities`` field should contain a union of
+	  all capabilities available around the several V4L2 devices
+	  exported to userspace. For all those devices the ``capabilities``
+	  field returns the same set of capabilities. This allows
+	  applications to open just one of the devices (typically the video
+	  device) and discover whether video, vbi and/or radio are also
+	  supported.
+
+    -  .. row 7

+
+       -  ``device_caps``
+

+	  capabilities and no video or vbi capabilities. This field is only
+	  set if the ``capabilities`` field contains the
+	  ``V4L2_CAP_DEVICE_CAPS`` capability. Only the ``capabilities``

+
+Description
+===========
+
+To query the attributes of a control applications set the ``id`` field
+of a struct :ref:`v4l2_queryctrl <v4l2-queryctrl>` and call the
+``VIDIOC_QUERYCTRL`` ioctl with a pointer to this structure. The driver
+fills the rest of the structure or returns an ``EINVAL`` error code when the
+``id`` is invalid.
+
+It is possible to enumerate controls by calling ``VIDIOC_QUERYCTRL``
+with successive ``id`` values starting from ``V4L2_CID_BASE`` up to and
+exclusive ``V4L2_CID_LASTP1``. Drivers may return ``EINVAL`` if a control in
+this range is not supported. Further applications can enumerate private
+controls, which are not defined in this specification, by starting at
+``V4L2_CID_PRIVATE_BASE`` and incrementing ``id`` until the driver
+returns ``EINVAL``.
+
+In both cases, when the driver sets the ``V4L2_CTRL_FLAG_DISABLED`` flag
+in the ``flags`` field this control is permanently disabled and should
+be ignored by the application. [#f1]_
+
+When the application ORs ``id`` with ``V4L2_CTRL_FLAG_NEXT_CTRL`` the
+driver returns the next supported non-compound control, or ``EINVAL`` if
+there is none. In addition, the ``V4L2_CTRL_FLAG_NEXT_COMPOUND`` flag
+can be specified to enumerate all compound controls (i.e. controls with
+type ≥ ``V4L2_CTRL_COMPOUND_TYPES`` and/or array control, in other words
+controls that contain more than one value). Specify both
+``V4L2_CTRL_FLAG_NEXT_CTRL`` and ``V4L2_CTRL_FLAG_NEXT_COMPOUND`` in
+order to enumerate all controls, compound or not. Drivers which do not
+support these flags yet always return ``EINVAL``.
+
+The ``VIDIOC_QUERY_EXT_CTRL`` ioctl was introduced in order to better
+support controls that can use compound types, and to expose additional
+control information that cannot be returned in struct
+:ref:`v4l2_queryctrl <v4l2-queryctrl>` since that structure is full.
+
+``VIDIOC_QUERY_EXT_CTRL`` is used in the same way as
+``VIDIOC_QUERYCTRL``, except that the ``reserved`` array must be zeroed
+as well.
+
+Additional information is required for menu controls: the names of the
+menu items. To query them applications set the ``id`` and ``index``
+fields of struct :ref:`v4l2_querymenu <v4l2-querymenu>` and call the
+``VIDIOC_QUERYMENU`` ioctl with a pointer to this structure. The driver
+fills the rest of the structure or returns an ``EINVAL`` error code when the
+``id`` or ``index`` is invalid. Menu items are enumerated by calling
+``VIDIOC_QUERYMENU`` with successive ``index`` values from struct
+:ref:`v4l2_queryctrl <v4l2-queryctrl>` ``minimum`` to ``maximum``,
+inclusive.
+
+.. note:: It is possible for ``VIDIOC_QUERYMENU`` to return
+   an ``EINVAL`` error code for some indices between ``minimum`` and
+   ``maximum``. In that case that particular menu item is not supported by
+   this driver. Also note that the ``minimum`` value is not necessarily 0.

+    greater than ``maximum``) or this particular menu item is not
+    supported by the driver.
+
+EACCES
+    An attempt was made to read a write-only control.
+
+.. [#f1]
+   ``V4L2_CTRL_FLAG_DISABLED`` was intended for two purposes: Drivers
+   can skip predefined controls not supported by the hardware (although
+   returning ``EINVAL`` would do as well), or disable predefined and private
+   controls after hardware detection without the trouble of reordering
+   control arrays and indices (``EINVAL`` cannot be used to skip private
+   controls because it would prematurely end the enumeration).

+
+
+Description
+===========
+
+The hardware may be able to detect the current video standard
+automatically. To do so, applications call :ref:`VIDIOC_QUERYSTD` with a
+pointer to a :ref:`v4l2_std_id <v4l2-std-id>` type. The driver
+stores here a set of candidates, this can be a single flag or a set of
+supported standards if for example the hardware can only distinguish
+between 50 and 60 Hz systems. If no signal was detected, then the driver
+will return V4L2_STD_UNKNOWN. When detection is not possible or fails,
+the set must contain all standards supported by the current video input
+or output.
+
+.. note:: Drivers shall *not* switch the video standard
+   automatically if a new video standard is detected. Instead, drivers
+   should send the ``V4L2_EVENT_SOURCE_CHANGE`` event (if they support
+   this) and expect that userspace will take action by calling
+   :ref:`VIDIOC_QUERYSTD`. The reason is that a new video standard can mean
+   different buffer sizes as well, and you cannot change buffer sizes on
+   the fly. In general, applications that receive the Source Change event
+   will have to call :ref:`VIDIOC_QUERYSTD`, and if the detected video
+   standard is valid they will have to stop streaming, set the new
+   standard, allocate new buffers and start streaming again.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+ENODATA
+    Standard video timings are not supported for this input or output.

+VIDIOC_REQBUFS - Initiate Memory Mapping, User Pointer I/O or DMA buffer I/O

+Synopsis
+========
+

+
+
+Arguments
+=========

+    VIDIOC_REQBUFS
+
+``argp``
+
+
+Description
+===========
+
+This ioctl is used to initiate :ref:`memory mapped <mmap>`,
+:ref:`user pointer <userp>` or :ref:`DMABUF <dmabuf>` based I/O.
+Memory mapped buffers are located in device memory and must be allocated
+with this ioctl before they can be mapped into the application's address
+space. User buffers are allocated by applications themselves, and this
+ioctl is merely used to switch the driver into user pointer I/O mode and
+to setup some internal structures. Similarly, DMABUF buffers are
+allocated by applications through a device driver, and this ioctl only
+configures the driver into DMABUF I/O mode without performing any direct
+allocation.
+
+To allocate device buffers applications initialize all fields of the
+:ref:`struct v4l2_requestbuffers <v4l2-requestbuffers>` structure. They set the ``type``
+field to the respective stream or buffer type, the ``count`` field to
+the desired number of buffers, ``memory`` must be set to the requested
+I/O method and the ``reserved`` array must be zeroed. When the ioctl is
+called with a pointer to this structure the driver will attempt to
+allocate the requested number of buffers and it stores the actual number
+allocated in the ``count`` field. It can be smaller than the number
+requested, even zero, when the driver runs out of free memory. A larger
+number is also possible when the driver requires more buffers to
+function correctly. For example video output requires at least two
+buffers, one displayed and one filled by the application.
+
+When the I/O method is not supported the ioctl returns an ``EINVAL`` error
+code.
+
+Applications can call :ref:`VIDIOC_REQBUFS` again to change the number of
+buffers, however this cannot succeed when any buffers are still mapped.
+A ``count`` value of zero frees all buffers, after aborting or finishing
+any DMA in progress, an implicit
+:ref:`VIDIOC_STREAMOFF <VIDIOC_STREAMON>`.

+Description
+===========
+
+Start a hardware frequency seek from the current frequency. To do this
+applications initialize the ``tuner``, ``type``, ``seek_upward``,
+``wrap_around``, ``spacing``, ``rangelow`` and ``rangehigh`` fields, and
+zero out the ``reserved`` array of a struct

+``VIDIOC_S_HW_FREQ_SEEK`` ioctl with a pointer to this structure.
+
+The ``rangelow`` and ``rangehigh`` fields can be set to a non-zero value
+to tell the driver to search a specific band. If the struct
+:ref:`v4l2_tuner <v4l2-tuner>` ``capability`` field has the
+``V4L2_TUNER_CAP_HWSEEK_PROG_LIM`` flag set, these values must fall
+within one of the bands returned by

+``V4L2_TUNER_CAP_HWSEEK_PROG_LIM`` flag is not set, then these values
+must exactly match those of one of the bands returned by
+:ref:`VIDIOC_ENUM_FREQ_BANDS`. If the
+current frequency of the tuner does not fall within the selected band it
+will be clamped to fit in the band before the seek is started.
+
+If an error is returned, then the original frequency will be restored.
+
+This ioctl is supported if the ``V4L2_CAP_HW_FREQ_SEEK`` capability is

+
+
+Description
+===========
+
+The ``VIDIOC_STREAMON`` and ``VIDIOC_STREAMOFF`` ioctl start and stop
+the capture or output process during streaming
+(:ref:`memory mapping <mmap>`, :ref:`user pointer <userp>` or
+:ref:`DMABUF <dmabuf>`) I/O.
+
+Capture hardware is disabled and no input buffers are filled (if there
+are any empty buffers in the incoming queue) until ``VIDIOC_STREAMON``
+has been called. Output hardware is disabled and no video signal is
+produced until ``VIDIOC_STREAMON`` has been called. The ioctl will
+succeed when at least one output buffer is in the incoming queue.
+
+Memory-to-memory devices will not start until ``VIDIOC_STREAMON`` has
+been called for both the capture and output stream types.
+
+If ``VIDIOC_STREAMON`` fails then any already queued buffers will remain
+queued.
+
+The ``VIDIOC_STREAMOFF`` ioctl, apart of aborting or finishing any DMA
+in progress, unlocks any user pointer buffers locked in physical memory,
+and it removes all buffers from the incoming and outgoing queues. That
+means all images captured but not dequeued yet will be lost, likewise
+all images enqueued for output but not transmitted yet. I/O returns to
+the same state as after calling
+:ref:`VIDIOC_REQBUFS` and can be restarted
+accordingly.
+
+If buffers have been queued with :ref:`VIDIOC_QBUF` and
+``VIDIOC_STREAMOFF`` is called without ever having called
+``VIDIOC_STREAMON``, then those queued buffers will also be removed from
+the incoming queue and all are returned to the same state as after
+calling :ref:`VIDIOC_REQBUFS` and can be restarted
+accordingly.
+
+Both ioctls take a pointer to an integer, the desired buffer or stream
+type. This is the same as struct
+:ref:`v4l2_requestbuffers <v4l2-requestbuffers>` ``type``.
+
+If ``VIDIOC_STREAMON`` is called when streaming is already in progress,
+or if ``VIDIOC_STREAMOFF`` is called when streaming is already stopped,
+then 0 is returned. Nothing happens in the case of ``VIDIOC_STREAMON``,
+but ``VIDIOC_STREAMOFF`` will return queued buffers to their starting
+state as mentioned above.
+
+.. note:: Applications can be preempted for unknown periods right before
+   or after the ``VIDIOC_STREAMON`` or ``VIDIOC_STREAMOFF`` calls, there is
+   no notion of starting or stopping "now". Buffer timestamps can be used
+   to synchronize with other events.

+Description
+===========
+
+This ioctl lets applications enumerate available frame intervals on a
+given sub-device pad. Frame intervals only makes sense for sub-devices
+that can control the frame period on their own. This includes, for
+instance, image sensors and TV tuners.
+
+For the common use case of image sensors, the frame intervals available
+on the sub-device output pad depend on the frame format and size on the
+same pad. Applications must thus specify the desired format and size
+when enumerating frame intervals.
+
+To enumerate frame intervals applications initialize the ``index``,
+``pad``, ``which``, ``code``, ``width`` and ``height`` fields of struct
+:ref:`v4l2_subdev_frame_interval_enum <v4l2-subdev-frame-interval-enum>`
+and call the :ref:`VIDIOC_SUBDEV_ENUM_FRAME_INTERVAL` ioctl with a pointer
+to this structure. Drivers fill the rest of the structure or return an
+EINVAL error code if one of the input fields is invalid. All frame
+intervals are enumerable by beginning at index zero and incrementing by
+one until ``EINVAL`` is returned.
+
+Available frame intervals may depend on the current 'try' formats at
+other pads of the sub-device, as well as on the current active links.
+See :ref:`VIDIOC_SUBDEV_G_FMT` for more
+information about the try formats.
+
+Sub-devices that support the frame interval enumeration ioctl should
+implemented it on a single pad only. Its behaviour when supported on
+multiple pads of the same sub-device is not defined.

+maximum values.
+
+Not all possible sizes in given [minimum, maximum] ranges need to be
+supported. For instance, a scaler that uses a fixed-point scaling ratio
+might not be able to produce every frame size between the minimum and
+maximum values. Applications must use the
+:ref:`VIDIOC_SUBDEV_S_FMT <VIDIOC_SUBDEV_G_FMT>` ioctl to try the
+sub-device for an exact supported frame size.
+
+Available frame sizes may depend on the current 'try' formats at other
+pads of the sub-device, as well as on the current active links and the
+current values of V4L2 controls. See
+:ref:`VIDIOC_SUBDEV_G_FMT` for more
+information about try formats.

+
+    This is an :ref:`obsolete` interface and may be removed
+    in the future. It is superseded by
+    :ref:`the selection API <VIDIOC_SUBDEV_G_SELECTION>`.
+
+To retrieve the current crop rectangle applications set the ``pad``
+field of a struct :ref:`v4l2_subdev_crop <v4l2-subdev-crop>` to the
+desired pad number as reported by the media API and the ``which`` field

+to ``V4L2_SUBDEV_FORMAT_TRY``. When set, 'try' crop rectangles are not
+applied to the device by the driver, but are mangled exactly as active
+crop rectangles and stored in the sub-device file handle. Two
+applications querying the same sub-device would thus not interact with
+each other.
+
+Drivers must not return an error solely because the requested crop
+rectangle doesn't match the device capabilities. They must instead
+modify the rectangle to match what the hardware can provide. The
+modified format should be as close as possible to the original request.

+
+
+Description
+===========
+
+These ioctls are used to negotiate the frame format at specific subdev
+pads in the image pipeline.
+
+To retrieve the current format applications set the ``pad`` field of a
+struct :ref:`v4l2_subdev_format <v4l2-subdev-format>` to the desired
+pad number as reported by the media API and the ``which`` field to
+``V4L2_SUBDEV_FORMAT_ACTIVE``. When they call the
+``VIDIOC_SUBDEV_G_FMT`` ioctl with a pointer to this structure the
+driver fills the members of the ``format`` field.
+
+To change the current format applications set both the ``pad`` and
+``which`` fields and all members of the ``format`` field. When they call
+the ``VIDIOC_SUBDEV_S_FMT`` ioctl with a pointer to this structure the
+driver verifies the requested format, adjusts it based on the hardware
+capabilities and configures the device. Upon return the struct
+:ref:`v4l2_subdev_format <v4l2-subdev-format>` contains the current
+format as would be returned by a ``VIDIOC_SUBDEV_G_FMT`` call.
+
+Applications can query the device capabilities by setting the ``which``
+to ``V4L2_SUBDEV_FORMAT_TRY``. When set, 'try' formats are not applied
+to the device by the driver, but are changed exactly as active formats
+and stored in the sub-device file handle. Two applications querying the
+same sub-device would thus not interact with each other.
+
+For instance, to try a format at the output pad of a sub-device,
+applications would first set the try format at the sub-device input with
+the ``VIDIOC_SUBDEV_S_FMT`` ioctl. They would then either retrieve the
+default format at the output pad with the ``VIDIOC_SUBDEV_G_FMT`` ioctl,
+or set the desired output pad format with the ``VIDIOC_SUBDEV_S_FMT``
+ioctl and check the returned value.
+
+Try formats do not depend on active formats, but can depend on the
+current links configuration or sub-device controls value. For instance,
+a low-pass noise filter might crop pixels at the frame boundaries,
+modifying its output frame size.
+

+
+
+Description
+===========
+
+The selections are used to configure various image processing
+functionality performed by the subdevs which affect the image size. This
+currently includes cropping, scaling and composition.
+
+The selection API replaces
+:ref:`the old subdev crop API <VIDIOC_SUBDEV_G_CROP>`. All the
+function of the crop API, and more, are supported by the selections API.
+
+See :ref:`subdev` for more information on how each selection target
+affects the image processing pipeline inside the subdevice.
+
+
+Types of selection targets
+--------------------------
+
+There are two types of selection targets: actual and bounds. The actual
+targets are the targets which configure the hardware. The BOUNDS target
+will return a rectangle that contain all possible actual rectangles.
+
+
+Discovering supported features
+------------------------------
+
+To discover which targets are supported, the user can perform
+``VIDIOC_SUBDEV_G_SELECTION`` on them. Any unsupported target will
+return ``EINVAL``.
+
+Selection targets and flags are documented in
+:ref:`v4l2-selections-common`.

+	  to the filehandle that called that ioctl. For example, changing a
+	  control using :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>` will cause
+	  a V4L2_EVENT_CTRL to be sent back to that same filehandle.
+	  Normally such events are suppressed to prevent feedback loops
+	  where an application changes a control to a one value and then
+	  another, and then receives an event telling it that that control
+	  has changed to the first value.
+
+	  Since it can't tell whether that event was caused by another
+	  application or by the :ref:`VIDIOC_S_CTRL <VIDIOC_G_CTRL>`
+	  call it is hard to decide whether to set the control to the value
+	  in the event, or ignore it.
+
+	  Think carefully when you set this flag so you won't get into
+	  situations like that.
+
+
+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the

+***********
+YUV Formats
+***********
+
+YUV is the format native to TV broadcast and composite video signals. It
+separates the brightness information (Y) from the color information (U
+and V or Cb and Cr). The color information consists of red and blue
+*color difference* signals, this way the green component can be
+reconstructed by subtracting from the brightness component. See
+:ref:`colorspaces` for conversion examples. YUV was chosen because
+early television would only transmit brightness information. To add
+color in a way compatible with existing receivers a new signal carrier
+was added to transmit the color difference signals. Secondary in the YUV
+format the U and V components usually have lower resolution than the Y
+component. This is an analog video compression technique taking
+advantage of a property of the human visual system, being more sensitive
+to brightness information.

+The bttv driver
+===============
+
+Release notes for bttv
+----------------------
+
+You'll need at least these config options for bttv:
+
+.. code-block:: none
+
+	CONFIG_I2C=m
+	CONFIG_I2C_ALGOBIT=m
+	CONFIG_VIDEO_DEV=m
+
+The latest bttv version is available from http://bytesex.org/bttv/
+
+
+Make bttv work with your card
+-----------------------------
+
+Just try "modprobe bttv" and see if that works.
+
+If it doesn't bttv likely could not autodetect your card and needs some
+insmod options.  The most important insmod option for bttv is "card=n"
+to select the correct card type.  If you get video but no sound you've
+very likely specified the wrong (or no) card type.  A list of supported
+cards is in CARDLIST.bttv
+
+If bttv takes very long to load (happens sometimes with the cheap
+cards which have no tuner), try adding this to your modules.conf:
+
+.. code-block:: none
+
+	options i2c-algo-bit bit_test=1
+
+For the WinTV/PVR you need one firmware file from the driver CD:
+hcwamc.rbf.  The file is in the pvr45xxx.exe archive (self-extracting
+zip file, unzip can unpack it).  Put it into the /etc/pvr directory or
+use the firm_altera=<path> insmod option to point the driver to the
+location of the file.
+
+If your card isn't listed in CARDLIST.bttv or if you have trouble making
+audio work, you should read the Sound-FAQ.
+
+
+Autodetecting cards
+-------------------
+
+bttv uses the PCI Subsystem ID to autodetect the card type.  lspci lists
+the Subsystem ID in the second line, looks like this:
+
+.. code-block:: none
+
+	00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02)
+		Subsystem: Hauppauge computer works Inc. WinTV/GO
+		Flags: bus master, medium devsel, latency 32, IRQ 5
+		Memory at e2000000 (32-bit, prefetchable) [size=4K]
+
+only bt878-based cards can have a subsystem ID (which does not mean
+that every card really has one).  bt848 cards can't have a Subsystem
+ID and therefore can't be autodetected.  There is a list with the ID's
+in bttv-cards.c (in case you are intrested or want to mail patches
+with updates).
+
+
+Still doesn't work?
+-------------------
+
+I do NOT have a lab with 30+ different grabber boards and a
+PAL/NTSC/SECAM test signal generator at home, so I often can't
+reproduce your problems.  This makes debugging very difficult for me.
+If you have some knowledge and spare time, please try to fix this
+yourself (patches very welcome of course...)  You know: The linux
+slogan is "Do it yourself".
+
+There is a mailing list at
+http://vger.kernel.org/vger-lists.html#linux-media
+
+If you have trouble with some specific TV card, try to ask there
+instead of mailing me directly.  The chance that someone with the
+same card listens there is much higher...
+
+For problems with sound:  There are a lot of different systems used
+for TV sound all over the world.  And there are also different chips
+which decode the audio signal.  Reports about sound problems ("stereo
+does'nt work") are pretty useless unless you include some details
+about your hardware and the TV sound scheme used in your country (or
+at least the country you are living in).
+
+Modprobe options
+----------------
+
+Note: "modinfo <module>" prints various information about a kernel
+module, among them a complete and up-to-date list of insmod options.
+This list tends to be outdated because it is updated manually ...
+
+==========================================================================
+
+bttv.o
+
+.. code-block:: none
+
+	the bt848/878 (grabber chip) driver
+
+	insmod args:
+		card=n		card type, see CARDLIST for a list.
+		tuner=n		tuner type, see CARDLIST for a list.
+		radio=0/1	card supports radio
+		pll=0/1/2	pll settings
+			0: don't use PLL
+			1: 28 MHz crystal installed
+			2: 35 MHz crystal installed
+
+		triton1=0/1     for Triton1 (+others) compatibility
+		vsfx=0/1	yet another chipset bug compatibility bit
+				see README.quirks for details on these two.
+
+		bigendian=n	Set the endianness of the gfx framebuffer.
+				Default is native endian.
+		fieldnr=0/1	Count fields.  Some TV descrambling software
+				needs this, for others it only generates
+				50 useless IRQs/sec.  default is 0 (off).
+		autoload=0/1	autoload helper modules (tuner, audio).
+				default is 1 (on).
+		bttv_verbose=0/1/2  verbose level (at insmod time, while
+				looking at the hardware).  default is 1.
+		bttv_debug=0/1	debug messages (for capture).
+				default is 0 (off).
+		irq_debug=0/1	irq handler debug messages.
+				default is 0 (off).
+		gbuffers=2-32	number of capture buffers for mmap'ed capture.
+				default is 4.
+		gbufsize=	size of capture buffers. default and
+				maximum value is 0x208000 (~2MB)
+		no_overlay=0	Enable overlay on broken hardware.  There
+				are some chipsets (SIS for example) which
+				are known to have problems with the PCI DMA
+				push used by bttv.  bttv will disable overlay
+				by default on this hardware to avoid crashes.
+				With this insmod option you can override this.
+		no_overlay=1	Disable overlay. It should be used by broken
+				hardware that doesn't support PCI2PCI direct
+				transfers.
+		automute=0/1	Automatically mutes the sound if there is
+				no TV signal, on by default.  You might try
+				to disable this if you have bad input signal
+				quality which leading to unwanted sound
+				dropouts.
+		chroma_agc=0/1	AGC of chroma signal, off by default.
+		adc_crush=0/1	Luminance ADC crush, on by default.
+		i2c_udelay=     Allow reduce I2C speed. Default is 5 usecs
+				(meaning 66,67 Kbps). The default is the
+				maximum supported speed by kernel bitbang
+				algorithm. You may use lower numbers, if I2C
+				messages are lost (16 is known to work on
+				all supported cards).
+
+		bttv_gpio=0/1
+		gpiomask=
+		audioall=
+		audiomux=
+				See Sound-FAQ for a detailed description.
+
+	remap, card, radio and pll accept up to four comma-separated arguments
+	(for multiple boards).
+
+tuner.o
+
+.. code-block:: none
+
+	The tuner driver.  You need this unless you want to use only
+	with a camera or external tuner ...
+
+	insmod args:
+		debug=1		print some debug info to the syslog
+		type=n		type of the tuner chip. n as follows:
+				see CARDLIST for a complete list.
+		pal=[bdgil]	select PAL variant (used for some tuners
+				only, important for the audio carrier).
+
+tvaudio.o
+
+.. code-block:: none
+
+	new, experimental module which is supported to provide a single
+	driver for all simple i2c audio control chips (tda/tea*).
+
+	insmod args:
+		tda8425  = 1	enable/disable the support for the
+		tda9840  = 1	various chips.
+		tda9850  = 1	The tea6300 can't be autodetected and is
+		tda9855  = 1	therefore off by default, if you have
+		tda9873  = 1	this one on your card (STB uses these)
+		tda9874a = 1	you have to enable it explicitly.
+		tea6300  = 0	The two tda985x chips use the same i2c
+		tea6420  = 1	address and can't be disturgished from
+		pic16c54 = 1	each other, you might have to disable
+				the wrong one.
+		debug = 1	print debug messages
+
+	insmod args for tda9874a:
+		tda9874a_SIF=1/2	select sound IF input pin (1 or 2)
+					(default is pin 1)
+		tda9874a_AMSEL=0/1	auto-mute select for NICAM (default=0)
+					Please read note 3 below!
+		tda9874a_STD=n		select TV sound standard (0..8):
+					0 - A2, B/G
+					1 - A2, M (Korea)
+					2 - A2, D/K (1)
+					3 - A2, D/K (2)
+					4 - A2, D/K (3)
+					5 - NICAM, I
+					6 - NICAM, B/G
+					7 - NICAM, D/K (default)
+					8 - NICAM, L
+
+	Note 1: tda9874a supports both tda9874h (old) and tda9874a (new) chips.
+	Note 2: tda9874h/a and tda9875 (which is supported separately by
+	tda9875.o) use the same i2c address so both modules should not be
+	used at the same time.
+	Note 3: Using tda9874a_AMSEL option depends on your TV card design!
+		AMSEL=0: auto-mute will switch between NICAM sound
+			 and the sound on 1st carrier (i.e. FM mono or AM).
+		AMSEL=1: auto-mute will switch between NICAM sound
+			 and the analog mono input (MONOIN pin).
+	If tda9874a decoder on your card has MONOIN pin not connected, then
+	use only tda9874_AMSEL=0 or don't specify this option at all.
+	For example:
+	  card=65 (FlyVideo 2000S) - set AMSEL=1 or AMSEL=0
+	  card=72 (Prolink PV-BT878P rev.9B) - set AMSEL=0 only
+
+msp3400.o
+
+.. code-block:: none
+
+	The driver for the msp34xx sound processor chips. If you have a
+	stereo card, you probably want to insmod this one.
+
+	insmod args:
+		debug=1/2	print some debug info to the syslog,
+				2 is more verbose.
+		simple=1	Use the "short programming" method.  Newer
+				msp34xx versions support this.  You need this
+				for dbx stereo.  Default is on if supported by
+				the chip.
+		once=1		Don't check the TV-stations Audio mode
+				every few seconds, but only once after
+				channel switches.
+		amsound=1	Audio carrier is AM/NICAM at 6.5 Mhz.  This
+				should improve things for french people, the
+				carrier autoscan seems to work with FM only...
+
+tea6300.o - OBSOLETE (use tvaudio instead)
+
+.. code-block:: none
+
+	The driver for the tea6300 fader chip.  If you have a stereo
+	card and the msp3400.o doesn't work, you might want to try this
+	one.  This chip is seen on most STB TV/FM cards (usually from
+	Gateway OEM sold surplus on auction sites).
+
+	insmod args:
+		debug=1		print some debug info to the syslog.
+
+tda8425.o - OBSOLETE (use tvaudio instead)
+
+.. code-block:: none
+
+	The driver for the tda8425 fader chip.  This driver used to be
+	part of bttv.c, so if your sound used to work but does not
+	anymore, try loading this module.
+
+	insmod args:
+		debug=1		print some debug info to the syslog.
+
+tda985x.o - OBSOLETE (use tvaudio instead)
+
+.. code-block:: none
+
+	The driver for the tda9850/55 audio chips.
+
+	insmod args:
+		debug=1		print some debug info to the syslog.
+		chip=9850/9855	set the chip type.
+
+
+If the box freezes hard with bttv
+---------------------------------
+
+It might be a bttv driver bug.  It also might be bad hardware.  It also
+might be something else ...
+
+Just mailing me "bttv freezes" isn't going to help much.  This README
+has a few hints how you can help to pin down the problem.
+
+
+bttv bugs
+~~~~~~~~~
+
+If some version works and another doesn't it is likely to be a driver
+bug.  It is very helpful if you can tell where exactly it broke
+(i.e. the last working and the first broken version).
+
+With a hard freeze you probably doesn't find anything in the logfiles.
+The only way to capture any kernel messages is to hook up a serial
+console and let some terminal application log the messages.  /me uses
+screen.  See Documentation/serial-console.txt for details on setting
+up a serial console.
+
+Read Documentation/oops-tracing.txt to learn how to get any useful
+information out of a register+stack dump printed by the kernel on
+protection faults (so-called "kernel oops").
+
+If you run into some kind of deadlock, you can try to dump a call trace
+for each process using sysrq-t (see Documentation/sysrq.txt).
+This way it is possible to figure where *exactly* some process in "D"
+state is stuck.
+
+I've seen reports that bttv 0.7.x crashes whereas 0.8.x works rock solid
+for some people.  Thus probably a small buglet left somewhere in bttv
+0.7.x.  I have no idea where exactly, it works stable for me and a lot of
+other people.  But in case you have problems with the 0.7.x versions you
+can give 0.8.x a try ...
+
+
+hardware bugs
+~~~~~~~~~~~~~
+
+Some hardware can't deal with PCI-PCI transfers (i.e. grabber => vga).
+Sometimes problems show up with bttv just because of the high load on
+the PCI bus. The bt848/878 chips have a few workarounds for known
+incompatibilities, see README.quirks.
+
+Some folks report that increasing the pci latency helps too,
+althrought I'm not sure whenever this really fixes the problems or
+only makes it less likely to happen.  Both bttv and btaudio have a
+insmod option to set the PCI latency of the device.
+
+Some mainboard have problems to deal correctly with multiple devices
+doing DMA at the same time.  bttv + ide seems to cause this sometimes,
+if this is the case you likely see freezes only with video and hard disk
+access at the same time.  Updating the IDE driver to get the latest and
+greatest workarounds for hardware bugs might fix these problems.
+
+
+other
+~~~~~
+
+If you use some binary-only yunk (like nvidia module) try to reproduce
+the problem without.
+
+IRQ sharing is known to cause problems in some cases.  It works just
+fine in theory and many configurations.  Neverless it might be worth a
+try to shuffle around the PCI cards to give bttv another IRQ or make
+it share the IRQ with some other piece of hardware.  IRQ sharing with
+VGA cards seems to cause trouble sometimes.  I've also seen funny
+effects with bttv sharing the IRQ with the ACPI bridge (and
+apci-enabled kernel).
+
+Bttv quirks
+-----------
+
+Below is what the bt878 data book says about the PCI bug compatibility
+modes of the bt878 chip.
+
+The triton1 insmod option sets the EN_TBFX bit in the control register.
+The vsfx insmod option does the same for EN_VSFX bit.  If you have
+stability problems you can try if one of these options makes your box
+work solid.
+
+drivers/pci/quirks.c knows about these issues, this way these bits are
+enabled automagically for known-buggy chipsets (look at the kernel
+messages, bttv tells you).
+
+Normal PCI Mode
+~~~~~~~~~~~~~~~
+
+The PCI REQ signal is the logical-or of the incoming function requests.
+The inter-nal GNT[0:1] signals are gated asynchronously with GNT and
+demultiplexed by the audio request signal. Thus the arbiter defaults to
+the video function at power-up and parks there during no requests for
+bus access. This is desirable since the video will request the bus more
+often. However, the audio will have highest bus access priority. Thus
+the audio will have first access to the bus even when issuing a request
+after the video request but before the PCI external arbiter has granted
+access to the Bt879. Neither function can preempt the other once on the
+bus. The duration to empty the entire video PCI FIFO onto the PCI bus is
+very short compared to the bus access latency the audio PCI FIFO can
+tolerate.
+
+
+430FX Compatibility Mode
+~~~~~~~~~~~~~~~~~~~~~~~~
+
+When using the 430FX PCI, the following rules will ensure
+compatibility:
+
+ (1) Deassert REQ at the same time as asserting FRAME.
+ (2) Do not reassert REQ to request another bus transaction until after
+     finish-ing the previous transaction.
+
+Since the individual bus masters do not have direct control of REQ, a
+simple logical-or of video and audio requests would violate the rules.
+Thus, both the arbiter and the initiator contain 430FX compatibility
+mode logic. To enable 430FX mode, set the EN_TBFX bit as indicated in
+Device Control Register on page 104.
+
+When EN_TBFX is enabled, the arbiter ensures that the two compatibility
+rules are satisfied. Before GNT is asserted by the PCI arbiter, this
+internal arbiter may still logical-or the two requests. However, once
+the GNT is issued, this arbiter must lock in its decision and now route
+only the granted request to the REQ pin. The arbiter decision lock
+happens regardless of the state of FRAME because it does not know when
+FRAME will be asserted (typically - each initiator will assert FRAME on
+the cycle following GNT). When FRAME is asserted, it is the initiator s
+responsibility to remove its request at the same time. It is the
+arbiters responsibility to allow this request to flow through to REQ and
+not allow the other request to hold REQ asserted. The decision lock may
+be removed at the end of the transaction: for example, when the bus is
+idle (FRAME and IRDY). The arbiter decision may then continue
+asynchronously until GNT is again asserted.
+
+
+Interfacing with Non-PCI 2.1 Compliant Core Logic
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+A small percentage of core logic devices may start a bus transaction
+during the same cycle that GNT is de-asserted. This is non PCI 2.1
+compliant. To ensure compatibility when using PCs with these PCI
+controllers, the EN_VSFX bit must be enabled (refer to Device Control
+Register on page 104). When in this mode, the arbiter does not pass GNT
+to the internal functions unless REQ is asserted. This prevents a bus
+transaction from starting the same cycle as GNT is de-asserted. This
+also has the side effect of not being able to take advantage of bus
+parking, thus lowering arbitration performance. The Bt879 drivers must
+query for these non-compliant devices, and set the EN_VSFX bit only if
+required.
+
+bttv and sound mini howto
+-------------------------
+
+There are a lot of different bt848/849/878/879 based boards available.
+Making video work often is not a big deal, because this is handled
+completely by the bt8xx chip, which is common on all boards.  But
+sound is handled in slightly different ways on each board.
+
+To handle the grabber boards correctly, there is a array tvcards[] in
+bttv-cards.c, which holds the information required for each board.
+Sound will work only, if the correct entry is used (for video it often
+makes no difference).  The bttv driver prints a line to the kernel
+log, telling which card type is used.  Like this one:
+
+.. code-block:: none
+
+	bttv0: model: BT848(Hauppauge old) [autodetected]
+
+You should verify this is correct.  If it isn't, you have to pass the
+correct board type as insmod argument, "insmod bttv card=2" for
+example.  The file CARDLIST has a list of valid arguments for card.
+If your card isn't listed there, you might check the source code for
+new entries which are not listed yet.  If there isn't one for your
+card, you can check if one of the existing entries does work for you
+(just trial and error...).
+
+Some boards have an extra processor for sound to do stereo decoding
+and other nice features.  The msp34xx chips are used by Hauppauge for
+example.  If your board has one, you might have to load a helper
+module like msp3400.o to make sound work.  If there isn't one for the
+chip used on your board:  Bad luck.  Start writing a new one.  Well,
+you might want to check the video4linux mailing list archive first...
+
+Of course you need a correctly installed soundcard unless you have the
+speakers connected directly to the grabber board.  Hint: check the
+mixer settings too.  ALSA for example has everything muted by default.
+
+
+How sound works in detail
+~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Still doesn't work?  Looks like some driver hacking is required.
+Below is a do-it-yourself description for you.
+
+The bt8xx chips have 32 general purpose pins, and registers to control
+these pins.  One register is the output enable register
+(BT848_GPIO_OUT_EN), it says which pins are actively driven by the
+bt848 chip.  Another one is the data register (BT848_GPIO_DATA), where
+you can get/set the status if these pins.  They can be used for input
+and output.
+
+Most grabber board vendors use these pins to control an external chip
+which does the sound routing.  But every board is a little different.
+These pins are also used by some companies to drive remote control
+receiver chips.  Some boards use the i2c bus instead of the gpio pins
+to connect the mux chip.
+
+As mentioned above, there is a array which holds the required
+information for each known board.  You basically have to create a new
+line for your board.  The important fields are these two:
+
+.. code-block:: c
+
+	struct tvcard
+	{
+		[ ... ]
+		u32 gpiomask;
+		u32 audiomux[6]; /* Tuner, Radio, external, internal, mute, stereo */
+	};
+
+gpiomask specifies which pins are used to control the audio mux chip.
+The corresponding bits in the output enable register
+(BT848_GPIO_OUT_EN) will be set as these pins must be driven by the
+bt848 chip.
+
+The audiomux\[\] array holds the data values for the different inputs
+(i.e. which pins must be high/low for tuner/mute/...).  This will be
+written to the data register (BT848_GPIO_DATA) to switch the audio
+mux.
+
+
+What you have to do is figure out the correct values for gpiomask and
+the audiomux array.  If you have Windows and the drivers four your
+card installed, you might to check out if you can read these registers
+values used by the windows driver.  A tool to do this is available
+from ftp://telepresence.dmem.strath.ac.uk/pub/bt848/winutil, but it
+doesn't work with bt878 boards according to some reports I received.
+Another one with bt878 support is available from
+http://btwincap.sourceforge.net/Files/btspy2.00.zip
+
+You might also dig around in the \*.ini files of the Windows applications.
+You can have a look at the board to see which of the gpio pins are
+connected at all and then start trial-and-error ...
+
+
+Starting with release 0.7.41 bttv has a number of insmod options to
+make the gpio debugging easier:
+
+.. code-block:: none
+
+	bttv_gpio=0/1		enable/disable gpio debug messages
+	gpiomask=n		set the gpiomask value
+	audiomux=i,j,...	set the values of the audiomux array
+	audioall=a		set the values of the audiomux array (one
+				value for all array elements, useful to check
+				out which effect the particular value has).
+
+The messages printed with bttv_gpio=1 look like this:
+
+.. code-block:: none
+
+	bttv0: gpio: en=00000027, out=00000024 in=00ffffd8 [audio: off]
+
+	en  =	output _en_able register (BT848_GPIO_OUT_EN)
+	out =	_out_put bits of the data register (BT848_GPIO_DATA),
+		i.e. BT848_GPIO_DATA & BT848_GPIO_OUT_EN
+	in  = 	_in_put bits of the data register,
+		i.e. BT848_GPIO_DATA & ~BT848_GPIO_OUT_EN
+
+
+
+Other elements of the tvcards array
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+If you are trying to make a new card work you might find it useful to
+know what the other elements in the tvcards array are good for:
+
+.. code-block:: none
+
+	video_inputs    - # of video inputs the card has
+	audio_inputs    - historical cruft, not used any more.
+	tuner           - which input is the tuner
+	svhs            - which input is svhs (all others are labeled composite)
+	muxsel          - video mux, input->registervalue mapping
+	pll             - same as pll= insmod option
+	tuner_type      - same as tuner= insmod option
+	*_modulename    - hint whenever some card needs this or that audio
+			module loaded to work properly.
+	has_radio	- whenever this TV card has a radio tuner.
+	no_msp34xx	- "1" disables loading of msp3400.o module
+	no_tda9875	- "1" disables loading of tda9875.o module
+	needs_tvaudio	- set to "1" to load tvaudio.o module
+
+If some config item is specified both from the tvcards array and as
+insmod option, the insmod option takes precedence.

+Author of this section: Jon Tombs <jon@gte.esi.us.es>
+
+This card is basically the same as all the rest (Bt484A, Philips tuner),
+the main difference is that they have attached a programmable attenuator to 3
+GPIO lines in order to give some volume control. They have also stuck an
+infra-red remote control decoded on the board, I will add support for this
+when I get time (it simple generates an interrupt for each key press, with
+the key code is placed in the GPIO port).
+
+I don't yet have any application to test the radio support. The tuner
+frequency setting should work but it is possible that the audio multiplexer
+is wrong. If it doesn't work, send me email.
+
+
+- No Thanks to Leadtek they refused to answer any questions about their
+  hardware. The driver was written by visual inspection of the card. If you
+  use this driver, send an email insult to them, and tell them you won't
+  continue buying their hardware unless they support Linux.

+To use the driver I use the following options, the tuner and pll settings might
+be different in your country

+The cpia2 driver
+================
+
+Authors: Peter Pregler <Peter_Pregler@email.com>,
+Scott J. Bertin <scottbertin@yahoo.com>, and
+Jarl Totland <Jarl.Totland@bdc.no> for the original cpia driver, which
+this one was modelled from.
+
+Introduction
+------------
+
+This is a driver for STMicroelectronics's CPiA2 (second generation
+Colour Processor Interface ASIC) based cameras. This camera outputs an MJPEG
+stream at up to vga size. It implements the Video4Linux interface as much as
+possible.  Since the V4L interface does not support compressed formats, only
+an mjpeg enabled application can be used with the camera. We have modified the
+gqcam application to view this stream.
+
+The driver is implemented as two kernel modules. The cpia2 module
+contains the camera functions and the V4L interface.  The cpia2_usb module
+contains usb specific functions.  The main reason for this was the size of the
+module was getting out of hand, so I separated them.  It is not likely that
+there will be a parallel port version.
+
+Features
+--------
+
+- Supports cameras with the Vision stv6410 (CIF) and stv6500 (VGA) cmos
+  sensors. I only have the vga sensor, so can't test the other.
+- Image formats: VGA, QVGA, CIF, QCIF, and a number of sizes in between.
+  VGA and QVGA are the native image sizes for the VGA camera. CIF is done
+  in the coprocessor by scaling QVGA.  All other sizes are done by clipping.
+- Palette: YCrCb, compressed with MJPEG.
+- Some compression parameters are settable.
+- Sensor framerate is adjustable (up to 30 fps CIF, 15 fps VGA).
+- Adjust brightness, color, contrast while streaming.
+- Flicker control settable for 50 or 60 Hz mains frequency.
+
+Making and installing the stv672 driver modules
+-----------------------------------------------
+
+Requirements
+~~~~~~~~~~~~
+
+Video4Linux must be either compiled into the kernel or
+available as a module.  Video4Linux2 is automatically detected and made
+available at compile time.
+
+Setup
+~~~~~
+
+Use 'modprobe cpia2' to load and 'modprobe -r cpia2' to unload. This
+may be done automatically by your distribution.
+
+Driver options
+~~~~~~~~~~~~~~
+
+==============  ========================================================
+Option		Description
+==============  ========================================================
+video_nr	video device to register (0=/dev/video0, etc)
+		range -1 to 64.  default is -1 (first available)
+		If you have more than 1 camera, this MUST be -1.
+buffer_size	Size for each frame buffer in bytes (default 68k)
+num_buffers	Number of frame buffers (1-32, default 3)
+alternate	USB Alternate (2-7, default 7)
+flicker_freq	Frequency for flicker reduction(50 or 60, default 60)
+flicker_mode	0 to disable, or 1 to enable flicker reduction.
+		(default 0). This is only effective if the camera
+		uses a stv0672 coprocessor.
+==============  ========================================================
+
+Setting the options
+~~~~~~~~~~~~~~~~~~~
+
+If you are using modules, edit /etc/modules.conf and add an options
+line like this:
+
+.. code-block:: none
+
+	options cpia2 num_buffers=3 buffer_size=65535
+
+If the driver is compiled into the kernel, at boot time specify them
+like this:
+
+.. code-block:: none
+
+	cpia2.num_buffers=3 cpia2.buffer_size=65535
+
+What buffer size should I use?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+The maximum image size depends on the alternate you choose, and the
+frame rate achieved by the camera.  If the compression engine is able to
+keep up with the frame rate, the maximum image size is given by the table
+below.
+
+The compression engine starts out at maximum compression, and will
+increase image quality until it is close to the size in the table.  As long
+as the compression engine can keep up with the frame rate, after a short time
+the images will all be about the size in the table, regardless of resolution.
+
+At low alternate settings, the compression engine may not be able to
+compress the image enough and will reduce the frame rate by producing larger
+images.
+
+The default of 68k should be good for most users.  This will handle
+any alternate at frame rates down to 15fps.  For lower frame rates, it may
+be necessary to increase the buffer size to avoid having frames dropped due
+to insufficient space.
+

+
+Table: Image size(bytes)
+
+
+How many buffers should I use?
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+For normal streaming, 3 should give the best results.  With only 2,
+it is possible for the camera to finish sending one image just after a
+program has started reading the other.  If this happens, the driver must drop
+a frame.  The exception to this is if you have a heavily loaded machine.  In
+this case use 2 buffers.  You are probably not reading at the full frame rate.
+If the camera can send multiple images before a read finishes, it could
+overwrite the third buffer before the read finishes, leading to a corrupt
+image.  Single and double buffering have extra checks to avoid overwriting.
+
+Using the camera
+~~~~~~~~~~~~~~~~
+
+We are providing a modified gqcam application to view the output. In
+order to avoid confusion, here it is called mview.  There is also the qx5view
+program which can also control the lights on the qx5 microscope. MJPEG Tools
+(http://mjpeg.sourceforge.net) can also be used to record from the camera.
+
+Notes to developers
+~~~~~~~~~~~~~~~~~~~
+
+   - This is a driver version stripped of the 2.4 back compatibility
+     and old MJPEG ioctl API. See cpia2.sf.net for 2.4 support.
+
+Programmer's overview of cpia2 driver
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+Cpia2 is the second generation video coprocessor from VLSI Vision Ltd (now a
+division of ST Microelectronics).  There are two versions.  The first is the
+STV0672, which is capable of up to 30 frames per second (fps) in frame sizes
+up to CIF, and 15 fps for VGA frames.  The STV0676 is an improved version,
+which can handle up to 30 fps VGA.  Both coprocessors can be attached to two
+CMOS sensors - the vvl6410 CIF sensor and the vvl6500 VGA sensor.  These will
+be referred to as the 410 and the 500 sensors, or the CIF and VGA sensors.
+
+The two chipsets operate almost identically.  The core is an 8051 processor,
+running two different versions of firmware.  The 672 runs the VP4 video
+processor code, the 676 runs VP5.  There are a few differences in register
+mappings for the two chips.  In these cases, the symbols defined in the
+header files are marked with VP4 or VP5 as part of the symbol name.
+
+The cameras appear externally as three sets of registers. Setting register
+values is the only way to control the camera.  Some settings are
+interdependant, such as the sequence required to power up the camera. I will
+try to make note of all of these cases.
+
+The register sets are called blocks.  Block 0 is the system block.  This
+section is always powered on when the camera is plugged in.  It contains
+registers that control housekeeping functions such as powering up the video
+processor.  The video processor is the VP block.  These registers control
+how the video from the sensor is processed.  Examples are timing registers,
+user mode (vga, qvga), scaling, cropping, framerates, and so on.  The last
+block is the video compressor (VC).  The video stream sent from the camera is
+compressed as Motion JPEG (JPEGA).  The VC controls all of the compression
+parameters.  Looking at the file cpia2_registers.h, you can get a full view
+of these registers and the possible values for most of them.
+
+One or more registers can be set or read by sending a usb control message to
+the camera.  There are three modes for this.  Block mode requests a number
+of contiguous registers.  Random mode reads or writes random registers with
+a tuple structure containing address/value pairs.  The repeat mode is only
+used by VP4 to load a firmware patch.  It contains a starting address and
+a sequence of bytes to be written into a gpio port.

+The cx2341x firmware upload
+---------------------------
+
+This document describes how to upload the cx2341x firmware to the card.
+
+How to find
+~~~~~~~~~~~
+
+See the web pages of the various projects that uses this chip for information
+on how to obtain the firmware.
+
+The firmware stored in a Windows driver can be detected as follows:
+
+- Each firmware image is 256k bytes.
+- The 1st 32-bit word of the Encoder image is 0x0000da7
+- The 1st 32-bit word of the Decoder image is 0x00003a7
+- The 2nd 32-bit word of both images is 0xaa55bb66
+
+How to load
+~~~~~~~~~~~
+
+- Issue the FWapi command to stop the encoder if it is running. Wait for the
+  command to complete.
+- Issue the FWapi command to stop the decoder if it is running. Wait for the
+  command to complete.
+- Issue the I2C command to the digitizer to stop emitting VSYNC events.
+- Issue the FWapi command to halt the encoder's firmware.
+- Sleep for 10ms.
+- Issue the FWapi command to halt the decoder's firmware.
+- Sleep for 10ms.
+- Write 0x00000000 to register 0x2800 to stop the Video Display Module.
+- Write 0x00000005 to register 0x2D00 to stop the AO (audio output?).
+- Write 0x00000000 to register 0xA064 to ping? the APU.

+  to re-enable the VPU.
+- Sleep for 1 second.
+- Issue status API commands to both firmware images to verify.
+
+
+How to call the firmware API
+----------------------------
+
+The preferred calling convention is known as the firmware mailbox. The
+mailboxes are basically a fixed length array that serves as the call-stack.
+
+Firmware mailboxes can be located by searching the encoder and decoder memory
+for a 16 byte signature. That signature will be located on a 256-byte boundary.
+
+Signature:
+
+.. code-block:: none
+
+	0x78, 0x56, 0x34, 0x12, 0x12, 0x78, 0x56, 0x34,
+	0x34, 0x12, 0x78, 0x56, 0x56, 0x34, 0x12, 0x78
+
+The firmware implements 20 mailboxes of 20 32-bit words. The first 10 are
+reserved for API calls. The second 10 are used by the firmware for event
+notification.
+
+  ====== =================
+  Index  Name
+  ====== =================
+  0      Flags
+  1      Command
+  2      Return value
+  3      Timeout
+  4-19   Parameter/Result
+  ====== =================
+
+
+The flags are defined in the following table. The direction is from the
+perspective of the firmware.
+
+  ==== ========== ============================================
+  Bit  Direction  Purpose
+  ==== ========== ============================================
+  2    O          Firmware has processed the command.
+  1    I          Driver has finished setting the parameters.
+  0    I          Driver is using this mailbox.
+  ==== ========== ============================================
+
+The command is a 32-bit enumerator. The API specifics may be found in this
+chapter.
+
+The return value is a 32-bit enumerator. Only two values are currently defined:
+
+- 0=success
+- -1=command undefined.
+
+There are 16 parameters/results 32-bit fields. The driver populates these fields
+with values for all the parameters required by the call. The driver overwrites
+these fields with result values returned by the call.
+
+The timeout value protects the card from a hung driver thread. If the driver
+doesn't handle the completed call within the timeout specified, the firmware
+will reset that mailbox.
+
+To make an API call, the driver iterates over each mailbox looking for the
+first one available (bit 0 has been cleared). The driver sets that bit, fills
+in the command enumerator, the timeout value and any required parameters. The
+driver then sets the parameter ready bit (bit 1). The firmware scans the
+mailboxes for pending commands, processes them, sets the result code, populates
+the result value array with that call's return values and sets the call
+complete bit (bit 2). Once bit 2 is set, the driver should retrieve the results
+and clear all the flags. If the driver does not perform this task within the
+time set in the timeout register, the firmware will reset that mailbox.
+
+Event notifications are sent from the firmware to the host. The host tells the
+firmware which events it is interested in via an API call. That call tells the
+firmware which notification mailbox to use. The firmware signals the host via
+an interrupt. Only the 16 Results fields are used, the Flags, Command, Return
+value and Timeout words are not used.

+
+This list has been worked out through trial and error. There will be mistakes
+and omissions. Some registers have no obvious effect so it's hard to say what
+they do, while others interact with each other, or require a certain load
+sequence. Horizontal filter setup is one example, with six registers working
+in unison and requiring a certain load sequence to correctly configure. The
+indexed colour palette is much easier to set at just two registers, but again
+it requires a certain load sequence.
+
+Some registers are fussy about what they are set to. Load in a bad value & the
+decoder will fail. A firmware reload will often recover, but sometimes a reset
+is required. For registers containing size information, setting them to 0 is
+generally a bad idea. For other control registers i.e. 2878, you'll only find
+out what values are bad when it hangs.

+		Decoder horizontal Y alias trigger
+
+	These six registers control the horizontal aliasing filter for the Y plane.
+	The first five registers must all be loaded before accessing the trigger
+	(2818), as this register actually clocks the data through for the first
+	five.
+
+	To correctly program set the filter, this whole procedure must be done 16
+	times. The actual register contents are copied from a lookup-table in the
+	firmware which contains 4 different filter settings.

+	2830
+	bits 0:31

+
+	These six registers control the horizontal aliasing for the UV plane.
+	Operation is the same as the Y filter, with 2830 being the trigger
+	register.

+
+	bits 16:31
+		Decoder UV destination width in pixels
+
+	NOTE: For both registers, the resulting image must be fully visible on
+	screen. If the image exceeds the right edge both the source and destination
+	size must be adjusted to reflect the visible portion. For the source width,
+	you must take into account the scaling when calculating the new value.

+
+	Most of these registers either control horizontal scaling, or appear linked
+	to it in some way. Register 2854 contains the 'master' value & the other
+	registers can be calculated from that one. You must also remember to
+	correctly set the divider in Reg 2874.
+
+	To enlarge:
+		Reg 2854 = (source_width * 0x00200000) / destination_width
+		Reg 2874 = No divide
+
+	To reduce from full size down to half size:
+		Reg 2854 = (source_width/2 * 0x00200000) / destination width
+		Reg 2874 = Divide by 2
+
+	To reduce from half size down to quarter size:
+		Reg 2854 = (source_width/4 * 0x00200000) / destination width
+		Reg 2874 = Divide by 4
+
+	The result is always rounded up.

+		Decoder output horizontal offset.
+
+	Horizontal offset moves the video image right. A small left shift is

+

+
+	In normal usage, the first plane is Y & the second plane is UV. Though the

+	can be swapped. This isn't much use for the Y plane, but can be useful for
+	the UV plane.

+	---------------
+	2908
+	bits 0:31
+		Decoder vertical Y alias trigger
+
+	These three registers control the vertical aliasing filter for the Y plane.
+	Operation is similar to the horizontal Y filter (2804). The only real
+	difference is that there are only two registers to set before accessing
+	the trigger register (2908). As for the horizontal filter, the values are
+	taken from a lookup table in the firmware, and the procedure must be

+
+	When the bits-per-pixel is set to 8, the colour mode is ignored and
+	assumed to be 8 bit indexed. For 16 & 32 bits-per-pixel the colour depth
+	is honoured, and when using a colour depth that requires fewer bytes than
+	allocated the extra bytes are used as padding. So for a 32 bpp with 8 bit
+	index colour, there are 3 padding bytes per pixel. It's also possible to
+	select 16bpp with a 32 bit colour mode. This results in the pixel width
+	being doubled, but the color key will not work as expected in this mode.
+
+	Colour key is as it suggests. You designate a colour which will become
+	completely transparent. When using 565, 555 or 444 colour modes, the
+	colour key is always 16 bits wide. The colour to key on is set in Reg 2A18.
+
+	Local alpha works differently depending on the colour mode. For 32bpp & 8
+	bit indexed, local alpha is a per-pixel 256 step transparency, with 0 being
+	transparent and 255 being solid. For the 16bpp modes 555 & 444, the unused
+	bit(s) act as a simple transparency switch, with 0 being solid & 1 being
+	fully transparent. There is no local alpha support for 16bit 565.
+
+	Global alpha is a 256 step transparency that applies to the entire osd,
+	with 0 being transparent & 255 being solid.
+
+	It's possible to combine colour key, local alpha & global alpha.

+
+The cx231xx DMA engine
+----------------------
+
+
+This page describes the structures and procedures used by the cx2341x DMA
+engine.
+
+Introduction
+~~~~~~~~~~~~
+
+The cx2341x PCI interface is busmaster capable. This means it has a DMA
+engine to efficiently transfer large volumes of data between the card and main
+memory without requiring help from a CPU. Like most hardware, it must operate
+on contiguous physical memory. This is difficult to come by in large quantities
+on virtual memory machines.
+
+Therefore, it also supports a technique called "scatter-gather". The card can
+transfer multiple buffers in one operation. Instead of allocating one large
+contiguous buffer, the driver can allocate several smaller buffers.
+
+In practice, I've seen the average transfer to be roughly 80K, but transfers
+above 128K were not uncommon, particularly at startup. The 128K figure is
+important, because that is the largest block that the kernel can normally
+allocate. Even still, 128K blocks are hard to come by, so the driver writer is
+urged to choose a smaller block size and learn the scatter-gather technique.
+
+Mailbox #10 is reserved for DMA transfer information.
+
+Note: the hardware expects little-endian data ('intel format').
+
+Flow
+~~~~
+
+This section describes, in general, the order of events when handling DMA
+transfers. Detailed information follows this section.
+
+- The card raises the Encoder interrupt.
+- The driver reads the transfer type, offset and size from Mailbox #10.
+- The driver constructs the scatter-gather array from enough free dma buffers
+  to cover the size.
+- The driver schedules the DMA transfer via the ScheduleDMAtoHost API call.
+- The card raises the DMA Complete interrupt.
+- The driver checks the DMA status register for any errors.
+- The driver post-processes the newly transferred buffers.
+
+NOTE! It is possible that the Encoder and DMA Complete interrupts get raised
+simultaneously. (End of the last, start of the next, etc.)
+
+Mailbox #10
+~~~~~~~~~~~
+
+The Flags, Command, Return Value and Timeout fields are ignored.
+
+- Name:       Mailbox #10
+- Results[0]: Type: 0: MPEG.
+- Results[1]: Offset: The position relative to the card's memory space.
+- Results[2]: Size: The exact number of bytes to transfer.
+
+My speculation is that since the StartCapture API has a capture type of "RAW"
+available, that the type field will have other values that correspond to YUV
+and PCM data.
+
+Scatter-Gather Array
+~~~~~~~~~~~~~~~~~~~~
+
+The scatter-gather array is a contiguously allocated block of memory that
+tells the card the source and destination of each data-block to transfer.
+Card "addresses" are derived from the offset supplied by Mailbox #10. Host
+addresses are the physical memory location of the target DMA buffer.
+
+Each S-G array element is a struct of three 32-bit words. The first word is
+the source address, the second is the destination address. Both take up the
+entire 32 bits. The lowest 18 bits of the third word is the transfer byte
+count. The high-bit of the third word is the "last" flag. The last-flag tells
+the card to raise the DMA_DONE interrupt. From hard personal experience, if
+you forget to set this bit, the card will still "work" but the stream will
+most likely get corrupted.
+
+The transfer count must be a multiple of 256. Therefore, the driver will need
+to track how much data in the target buffer is valid and deal with it
+accordingly.
+
+Array Element:
+
+- 32-bit Source Address
+- 32-bit Destination Address
+- 14-bit reserved (high bit is the last flag)
+- 18-bit byte count
+
+DMA Transfer Status
+~~~~~~~~~~~~~~~~~~~
+
+Register 0x0004 holds the DMA Transfer Status:
+
+- bit 0:   read completed
+- bit 1:   write completed
+- bit 2:   DMA read error
+- bit 3:   DMA write error
+- bit 4:   Scatter-Gather array error
+
+Non-compressed file format
+--------------------------
+
+The cx23416 can produce (and the cx23415 can also read) raw YUV output. The
+format of a YUV frame is specific to this chip and is called HM12. 'HM' stands
+for 'Hauppauge Macroblock', which is a misnomer as 'Conexant Macroblock' would
+be more accurate.
+
+The format is YUV 4:2:0 which uses 1 Y byte per pixel and 1 U and V byte per
+four pixels.
+
+The data is encoded as two macroblock planes, the first containing the Y
+values, the second containing UV macroblocks.
+
+The Y plane is divided into blocks of 16x16 pixels from left to right
+and from top to bottom. Each block is transmitted in turn, line-by-line.
+
+So the first 16 bytes are the first line of the top-left block, the
+second 16 bytes are the second line of the top-left block, etc. After
+transmitting this block the first line of the block on the right to the
+first block is transmitted, etc.
+
+The UV plane is divided into blocks of 16x8 UV values going from left
+to right, top to bottom. Each block is transmitted in turn, line-by-line.
+
+So the first 16 bytes are the first line of the top-left block and
+contain 8 UV value pairs (16 bytes in total). The second 16 bytes are the
+second line of 8 UV pairs of the top-left block, etc. After transmitting
+this block the first line of the block on the right to the first block is
+transmitted, etc.
+
+The code below is given as an example on how to convert HM12 to separate
+Y, U and V planes. This code assumes frames of 720x576 (PAL) pixels.
+
+The width of a frame is always 720 pixels, regardless of the actual specified
+width.
+
+If the height is not a multiple of 32 lines, then the captured video is
+missing macroblocks at the end and is unusable. So the height must be a
+multiple of 32.

+Format of embedded V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data
+---------------------------------------------------------
+
+Author: Hans Verkuil <hverkuil@xs4all.nl>
+
+
+This section describes the V4L2_MPEG_STREAM_VBI_FMT_IVTV format of the VBI data
+embedded in an MPEG-2 program stream. This format is in part dictated by some
+hardware limitations of the ivtv driver (the driver for the Conexant cx23415/6
+chips), in particular a maximum size for the VBI data. Anything longer is cut
+off when the MPEG stream is played back through the cx23415.
+
+The advantage of this format is it is very compact and that all VBI data for
+all lines can be stored while still fitting within the maximum allowed size.
+
+The stream ID of the VBI data is 0xBD. The maximum size of the embedded data is
+4 + 43 * 36, which is 4 bytes for a header and 2 * 18 VBI lines with a 1 byte
+header and a 42 bytes payload each. Anything beyond this limit is cut off by
+the cx23415/6 firmware. Besides the data for the VBI lines we also need 36 bits
+for a bitmask determining which lines are captured and 4 bytes for a magic cookie,
+signifying that this data package contains V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data.
+If all lines are used, then there is no longer room for the bitmask. To solve this
+two different magic numbers were introduced:
+
+'itv0': After this magic number two unsigned longs follow. Bits 0-17 of the first
+unsigned long denote which lines of the first field are captured. Bits 18-31 of
+the first unsigned long and bits 0-3 of the second unsigned long are used for the
+second field.
+
+'ITV0': This magic number assumes all VBI lines are captured, i.e. it implicitly
+implies that the bitmasks are 0xffffffff and 0xf.
+
+After these magic cookies (and the 8 byte bitmask in case of cookie 'itv0') the
+captured VBI lines start:
+
+For each line the least significant 4 bits of the first byte contain the data type.
+Possible values are shown in the table below. The payload is in the following 42
+bytes.
+
+Here is the list of possible data types:
+
+.. code-block:: c
+
+	#define IVTV_SLICED_TYPE_TELETEXT       0x1     // Teletext (uses lines 6-22 for PAL)
+	#define IVTV_SLICED_TYPE_CC             0x4     // Closed Captions (line 21 NTSC)
+	#define IVTV_SLICED_TYPE_WSS            0x5     // Wide Screen Signal (line 23 PAL)
+	#define IVTV_SLICED_TYPE_VPS            0x7     // Video Programming System (PAL) (line 16)

+The cx88 driver
+===============
+
+Author:  Gerd Hoffmann
+
+This is a v4l2 device driver for the cx2388x chip.
+
+
+Current status
+--------------
+
+video
+	- Works.
+	- Overlay isn't supported.
+
+audio
+	- Works. The TV standard detection is made by the driver, as the
+	  hardware has bugs to auto-detect.
+	- audio data dma (i.e. recording without loopback cable to the
+	  sound card) is supported via cx88-alsa.
+
+vbi
+	- Works.
+
+
+How to add support for new cards
+--------------------------------
+
+The driver needs some config info for the TV cards.  This stuff is in
+cx88-cards.c.  If the driver doesn't work well you likely need a new
+entry for your card in that file.  Check the kernel log (using dmesg)
+to see whenever the driver knows your card or not.  There is a line

+		34xxx models [card=1,autodetected]
+
+If your card is listed as "board: UNKNOWN/GENERIC" it is unknown to
+the driver.  What to do then?
+
+1) Try upgrading to the latest snapshot, maybe it has been added
+   meanwhile.
+2) You can try to create a new entry yourself, have a look at
+   cx88-cards.c.  If that worked, mail me your changes as unified
+   diff ("diff -u").
+3) Or you can mail me the config information.  We need at least the
+   following information to add the card:
+
+     - the PCI Subsystem ID ("0070:3400" from the line above,
+       "lspci -v" output is fine too).
+     - the tuner type used by the card.  You can try to find one by
+       trial-and-error using the tuner=<n> insmod option.  If you
+       know which one the card has you can also have a look at the
+       list in CARDLIST.tuner

+
+Hauppauge WinTV cx88 IR information
+-----------------------------------
+
+The controls for the mux are GPIO [0,1] for source, and GPIO 2 for muting.
+
+====== ======== =================================================
+GPIO0  GPIO1
+====== ======== =================================================
+  0        0    TV Audio
+  1        0    FM radio
+  0        1    Line-In
+  1        1    Mono tuner bypass or CD passthru (tuner specific)
+====== ======== =================================================
+
+GPIO 16(I believe) is tied to the IR port (if present).
+
+
+From the data sheet:
+
+- Register 24'h20004  PCI Interrupt Status
+ - bit [18]  IR_SMP_INT Set when 32 input samples have been collected over
+ - gpio[16] pin into GP_SAMPLE register.
+
+What's missing from the data sheet:
+
+- Setup 4KHz sampling rate (roughly 2x oversampled; good enough for our RC5
+  compat remote)
+- set register 0x35C050 to  0xa80a80
+- enable sampling
+- set register 0x35C054 to 0x5
+- enable the IRQ bit 18 in the interrupt mask register (and
+  provide for a handler)
+
+GP_SAMPLE register is at 0x35C058
+
+Bits are then right shifted into the GP_SAMPLE register at the specified
+rate; you get an interrupt when a full DWORD is received.
+You need to recover the actual RC5 bits out of the (oversampled) IR sensor
+bits. (Hint: look for the 0/1and 1/0 crossings of the RC5 bi-phase data)  An
+actual raw RC5 code will span 2-3 DWORDS, depending on the actual alignment.
+
+I'm pretty sure when no IR signal is present the receiver is always in a
+marking state(1); but stray light, etc can cause intermittent noise values
+as well.  Remember, this is a free running sample of the IR receiver state
+over time, so don't assume any sample starts at any particular place.

+The ivtv driver
+===============
+
+Author: Hans Verkuil <hverkuil@xs4all.nl>
+
+This is a v4l2 device driver for the Conexant cx23415/6 MPEG encoder/decoder.
+The cx23415 can do both encoding and decoding, the cx23416 can only do MPEG
+encoding. Currently the only card featuring full decoding support is the
+Hauppauge PVR-350.
+
+.. note::
+
+   #) This driver requires the latest encoder firmware (version 2.06.039, size
+      376836 bytes). Get the firmware from here:
+
+      https://linuxtv.org/downloads/firmware/#conexant
+
+   #) 'normal' TV applications do not work with this driver, you need
+      an application that can handle MPEG input such as mplayer, xine, MythTV,
+      etc.
+
+The primary goal of the IVTV project is to provide a "clean room" Linux
+Open Source driver implementation for video capture cards based on the
+iCompression iTVC15 or Conexant CX23415/CX23416 MPEG Codec.
+
+Features
+--------
+
+ * Hardware mpeg2 capture of broadcast video (and sound) via the tuner or
+   S-Video/Composite and audio line-in.
+ * Hardware mpeg2 capture of FM radio where hardware support exists
+ * Supports NTSC, PAL, SECAM with stereo sound
+ * Supports SAP and bilingual transmissions.
+ * Supports raw VBI (closed captions and teletext).
+ * Supports sliced VBI (closed captions and teletext) and is able to insert
+   this into the captured MPEG stream.
+ * Supports raw YUV and PCM input.
+
+Additional features for the PVR-350 (CX23415 based)
+---------------------------------------------------
+
+ * Provides hardware mpeg2 playback
+ * Provides comprehensive OSD (On Screen Display: ie. graphics overlaying the
+   video signal)
+ * Provides a framebuffer (allowing X applications to appear on the video
+   device)
+ * Supports raw YUV output.

+
+Devices
+-------
+
+A maximum of 12 ivtv boards are allowed at the moment.
+
+Cards that don't have a video output capability (i.e. non PVR350 cards)
+lack the vbi8, vbi16, video16 and video48 devices. They also do not
+support the framebuffer device /dev/fbx for OSD.
+
+The radio0 device may or may not be present, depending on whether the
+card has a radio tuner or not.
+
+Here is a list of the base v4l devices:
+
+.. code-block:: none
+
+	crw-rw----    1 root     video     81,   0 Jun 19 22:22 /dev/video0

+
+Base devices
+------------
+
+For every extra card you have the numbers increased by one. For example,
+/dev/video0 is listed as the 'base' encoding capture device so we have:
+
+- /dev/video0  is the encoding capture device for the first card (card 0)
+- /dev/video1  is the encoding capture device for the second card (card 1)
+- /dev/video2  is the encoding capture device for the third card (card 2)
+
+Note that if the first card doesn't have a feature (eg no decoder, so no
+video16, the second card will still use video17. The simple rule is 'add
+the card number to the base device number'. If you have other capture
+cards (e.g. WinTV PCI) that are detected first, then you have to tell
+the ivtv module about it so that it will start counting at 1 (or 2, or
+whatever). Otherwise the device numbers can get confusing. The ivtv
+'ivtv_first_minor' module option can be used for that.
+
+
+- /dev/video0
+
+  The encoding capture device(s).
+
+  Read-only.
+
+  Reading from this device gets you the MPEG1/2 program stream.
+  Example:
+
+  .. code-block:: none
+
+	cat /dev/video0 > my.mpg (you need to hit ctrl-c to exit)
+
+
+- /dev/video16
+
+  The decoder output device(s)
+
+  Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
+
+  An mpeg2 stream sent to this device will appear on the selected video
+  display, audio will appear on the line-out/audio out.  It is only
+  available for cards that support video out. Example:
+
+  .. code-block:: none
+
+	cat my.mpg >/dev/video16
+
+
+- /dev/video24
+
+  The raw audio capture device(s).
+
+  Read-only
+
+  The raw audio PCM stereo stream from the currently selected
+  tuner or audio line-in.  Reading from this device results in a raw
+  (signed 16 bit Little Endian, 48000 Hz, stereo pcm) capture.
+  This device only captures audio. This should be replaced by an ALSA
+  device in the future.
+  Note that there is no corresponding raw audio output device, this is
+  not supported in the decoder firmware.
+
+
+- /dev/video32
+
+  The raw video capture device(s)
+
+  Read-only
+
+  The raw YUV video output from the current video input. The YUV format
+  is non-standard (V4L2_PIX_FMT_HM12).
+
+  Note that the YUV and PCM streams are not synchronized, so they are of
+  limited use.
+
+
+- /dev/video48
+
+  The raw video display device(s)
+
+  Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
+
+  Writes a YUV stream to the decoder of the card.
+
+
+- /dev/radio0
+
+  The radio tuner device(s)
+
+  Cannot be read or written.
+
+  Used to enable the radio tuner and tune to a frequency. You cannot
+  read or write audio streams with this device.  Once you use this
+  device to tune the radio, use /dev/video24 to read the raw pcm stream
+  or /dev/video0 to get an mpeg2 stream with black video.
+
+
+- /dev/vbi0
+
+  The 'vertical blank interval' (Teletext, CC, WSS etc) capture device(s)
+
+  Read-only
+
+  Captures the raw (or sliced) video data sent during the Vertical Blank
+  Interval. This data is used to encode teletext, closed captions, VPS,
+  widescreen signalling, electronic program guide information, and other
+  services.
+
+
+- /dev/vbi8
+
+  Processed vbi feedback device(s)
+
+  Read-only. Only present if the MPEG decoder (i.e. CX23415) exists.
+
+  The sliced VBI data embedded in an MPEG stream is reproduced on this
+  device. So while playing back a recording on /dev/video16, you can
+  read the embedded VBI data from /dev/vbi8.
+
+
+- /dev/vbi16
+
+  The vbi 'display' device(s)
+
+  Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
+
+  Can be used to send sliced VBI data to the video-out connector.

+
+Constraints
+-----------
+
+a) Image size for YUV422P format
+   All YUV422P images are enforced to have width x height % 16 = 0.
+   This is due to DMA constraints, which transfers only planes of 8 byte
+   multiples.
+
+
+Global video workflow
+---------------------
+
+a) QCI stopped
+   Initialy, the QCI interface is stopped.
+   When a buffer is queued (pxa_videobuf_ops->buf_queue), the QCI starts.
+
+b) QCI started
+   More buffers can be queued while the QCI is started without halting the
+   capture.  The new buffers are "appended" at the tail of the DMA chain, and
+   smoothly captured one frame after the other.
+
+   Once a buffer is filled in the QCI interface, it is marked as "DONE" and
+   removed from the active buffers list. It can be then requeud or dequeued by
+   userland application.
+
+   Once the last buffer is filled in, the QCI interface stops.

+
+DMA usage
+---------
+
+a) DMA flow
+     - first buffer queued for capture
+       Once a first buffer is queued for capture, the QCI is started, but data
+       transfer is not started. On "End Of Frame" interrupt, the irq handler
+       starts the DMA chain.
+     - capture of one videobuffer
+       The DMA chain starts transferring data into videobuffer RAM pages.
+       When all pages are transferred, the DMA irq is raised on "ENDINTR" status
+     - finishing one videobuffer
+       The DMA irq handler marks the videobuffer as "done", and removes it from
+       the active running queue
+       Meanwhile, the next videobuffer (if there is one), is transferred by DMA
+     - finishing the last videobuffer
+       On the DMA irq of the last videobuffer, the QCI is stopped.
+
+b) DMA prepared buffer will have this structure
+
+.. code-block:: none
+
+     +------------+-----+---------------+-----------------+
+     | desc-sg[0] | ... | desc-sg[last] | finisher/linker |
+     +------------+-----+---------------+-----------------+
+
+This structure is pointed by dma->sg_cpu.
+The descriptors are used as follows:
+
+- desc-sg[i]: i-th descriptor, transferring the i-th sg
+  element to the video buffer scatter gather
+- finisher: has ddadr=DADDR_STOP, dcmd=ENDIRQEN
+- linker: has ddadr= desc-sg[0] of next video buffer, dcmd=0
+
+For the next schema, let's assume d0=desc-sg[0] .. dN=desc-sg[N],
+"f" stands for finisher and "l" for linker.
+A typical running chain is :
+
+.. code-block:: none
+
+         Videobuffer 1         Videobuffer 2
+     +---------+----+---+  +----+----+----+---+
+     | d0 | .. | dN | l |  | d0 | .. | dN | f |
+     +---------+----+-|-+  ^----+----+----+---+
+                      |    |
+                      +----+
+
+After the chaining is finished, the chain looks like :
+
+.. code-block:: none
+
+         Videobuffer 1         Videobuffer 2         Videobuffer 3
+     +---------+----+---+  +----+----+----+---+  +----+----+----+---+
+     | d0 | .. | dN | l |  | d0 | .. | dN | l |  | d0 | .. | dN | f |
+     +---------+----+-|-+  ^----+----+----+-|-+  ^----+----+----+---+
+                      |    |                |    |
+                      +----+                +----+
+                                           new_link
+
+c) DMA hot chaining timeslice issue
+
+As DMA chaining is done while DMA _is_ running, the linking may be done
+while the DMA jumps from one Videobuffer to another. On the schema, that
+would be a problem if the following sequence is encountered :
+
+- DMA chain is Videobuffer1 + Videobuffer2
+- pxa_videobuf_queue() is called to queue Videobuffer3
+- DMA controller finishes Videobuffer2, and DMA stops
+
+.. code-block:: none
+
+      =>
+         Videobuffer 1         Videobuffer 2
+     +---------+----+---+  +----+----+----+---+
+     | d0 | .. | dN | l |  | d0 | .. | dN | f |
+     +---------+----+-|-+  ^----+----+----+-^-+
+                      |    |                |
+                      +----+                +-- DMA DDADR loads DDADR_STOP
+
+- pxa_dma_add_tail_buf() is called, the Videobuffer2 "finisher" is
+  replaced by a "linker" to Videobuffer3 (creation of new_link)
+- pxa_videobuf_queue() finishes
+- the DMA irq handler is called, which terminates Videobuffer2
+- Videobuffer3 capture is not scheduled on DMA chain (as it stopped !!!)
+
+.. code-block:: none
+
+         Videobuffer 1         Videobuffer 2         Videobuffer 3
+     +---------+----+---+  +----+----+----+---+  +----+----+----+---+
+     | d0 | .. | dN | l |  | d0 | .. | dN | l |  | d0 | .. | dN | f |
+     +---------+----+-|-+  ^----+----+----+-|-+  ^----+----+----+---+
+                      |    |                |    |
+                      +----+                +----+
+                                           new_link
+                                          DMA DDADR still is DDADR_STOP
+
+- pxa_camera_check_link_miss() is called
+  This checks if the DMA is finished and a buffer is still on the
+  pcdev->capture list. If that's the case, the capture will be restarted,
+  and Videobuffer3 is scheduled on DMA chain.
+- the DMA irq handler finishes
+
+.. note::
+
+     If DMA stops just after pxa_camera_check_link_miss() reads DDADR()
+     value, we have the guarantee that the DMA irq handler will be called back
+     when the DMA will finish the buffer, and pxa_camera_check_link_miss() will
+     be called again, to reschedule Videobuffer3.

+The Radiotrack radio driver
+===========================
+
+Author: Stephen M. Benoit <benoits@servicepro.com>
+
+Date:  Dec 14, 1996
+
+ACKNOWLEDGMENTS
+----------------
+
+This document was made based on 'C' code for Linux from Gideon le Grange
+(legrang@active.co.za or legrang@cs.sun.ac.za) in 1994, and elaborations from
+Frans Brinkman (brinkman@esd.nl) in 1996.  The results reported here are from
+experiments that the author performed on his own setup, so your mileage may
+vary... I make no guarantees, claims or warranties to the suitability or
+validity of this information.  No other documentation on the AIMS
+Lab (http://www.aimslab.com/) RadioTrack card was made available to the
+author.  This document is offered in the hopes that it might help users who
+want to use the RadioTrack card in an environment other than MS Windows.
+
+WHY THIS DOCUMENT?
+------------------
+
+I have a RadioTrack card from back when I ran an MS-Windows platform.  After
+converting to Linux, I found Gideon le Grange's command-line software for
+running the card, and found that it was good!  Frans Brinkman made a
+comfortable X-windows interface, and added a scanning feature.  For hack
+value, I wanted to see if the tuner could be tuned beyond the usual FM radio
+broadcast band, so I could pick up the audio carriers from North American
+broadcast TV channels, situated just below and above the 87.0-109.0 MHz range.
+I did not get much success, but I learned about programming ioports under
+Linux and gained some insights about the hardware design used for the card.
+
+So, without further delay, here are the details.
+
+
+PHYSICAL DESCRIPTION
+--------------------
+
+The RadioTrack card is an ISA 8-bit FM radio card.  The radio frequency (RF)
+input is simply an antenna lead, and the output is a power audio signal
+available through a miniature phone plug.  Its RF frequencies of operation are
+more or less limited from 87.0 to 109.0 MHz (the commercial FM broadcast
+band).  Although the registers can be programmed to request frequencies beyond
+these limits, experiments did not give promising results.  The variable
+frequency oscillator (VFO) that demodulates the intermediate frequency (IF)
+signal probably has a small range of useful frequencies, and wraps around or
+gets clipped beyond the limits mentioned above.
+
+
+CONTROLLING THE CARD WITH IOPORT
+--------------------------------
+
+The RadioTrack (base) ioport is configurable for 0x30c or 0x20c.  Only one
+ioport seems to be involved.  The ioport decoding circuitry must be pretty
+simple, as individual ioport bits are directly matched to specific functions
+(or blocks) of the radio card.  This way, many functions can be changed in
+parallel with one write to the ioport.  The only feedback available through
+the ioports appears to be the "Stereo Detect" bit.
+
+The bits of the ioport are arranged as follows:
+
+.. code-block:: none
+
+	MSb                                                         LSb
+	+------+------+------+--------+--------+-------+---------+--------+
+	| VolA | VolB | ???? | Stereo | Radio  | TuneA | TuneB   | Tune   |
+	|  (+) |  (-) |      | Detect | Audio  | (bit) | (latch) | Update |
+	|      |      |      | Enable | Enable |       |         | Enable |

+The saa7134 driver
+==================
+
+Author Gerd Hoffmann
+
+
+This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV
+boards.  See http://www.semiconductors.philips.com/pip/saa7134hl for a
+description.
+
+
+Status
+------
+
+Almost everything is working.  video, sound, tuner, radio, mpeg ts, ...
+
+As with bttv, card-specific tweaks are needed.  Check CARDLIST for a
+list of known TV cards and saa7134-cards.c for the drivers card
+configuration info.
+
+
+Build
+-----
+
+Pick up videodev + v4l2 patches from http://bytesex.org/patches/.
+Configure, build, install + boot the new kernel.  You'll need at least
+these config options:
+
+.. code-block:: none
+
+	CONFIG_I2C=m
+	CONFIG_VIDEO_DEV=m
+
+Type "make" to build the driver now.  "make install" installs the
+driver.  "modprobe saa7134" should load it.  Depending on the card you
+might have to pass card=<nr> as insmod option, check CARDLIST for
+valid choices.
+
+
+Changes / Fixes
+---------------
+
+Please mail me unified diffs ("diff -u") with your changes, and don't
+forget to tell me what it changes / which problem it fixes / whatever
+it is good for ...
+
+
+Known Problems
+--------------
+
+* The tuner for the flyvideos isn't detected automatically and the
+  default might not work for you depending on which version you have.
+  There is a tuner= insmod option to override the driver's default.
+
+Card Variations:
+----------------
+
+Cards can use either of these two crystals (xtal):
+
+- 32.11 MHz -> .audio_clock=0x187de7
+- 24.576MHz -> .audio_clock=0x200000 (xtal * .audio_clock = 51539600)
+
+Some details about 30/34/35:
+
+- saa7130 - low-price chip, doesn't have mute, that is why all those
+  cards should have .mute field defined in their tuner structure.
+
+- saa7134 - usual chip
+
+- saa7133/35 - saa7135 is probably a marketing decision, since all those
+  chips identifies itself as 33 on pci.

+The Silicon Labs Si4713 FM Radio Transmitter Driver
+===================================================
+
+Copyright |copy| 2009 Nokia Corporation
+
+Contact: Eduardo Valentin <eduardo.valentin@nokia.com>
+
+
+Information about the Device
+----------------------------
+
+This chip is a Silicon Labs product. It is a I2C device, currently on 0x63 address.
+Basically, it has transmission and signal noise level measurement features.
+
+The Si4713 integrates transmit functions for FM broadcast stereo transmission.
+The chip also allows integrated receive power scanning to identify low signal
+power FM channels.
+
+The chip is programmed using commands and responses. There are also several
+properties which can change the behavior of this chip.
+
+Users must comply with local regulations on radio frequency (RF) transmission.
+
+Device driver description
+-------------------------
+
+There are two modules to handle this device. One is a I2C device driver
+and the other is a platform driver.
+
+The I2C device driver exports a v4l2-subdev interface to the kernel.
+All properties can also be accessed by v4l2 extended controls interface, by
+using the v4l2-subdev calls (g_ext_ctrls, s_ext_ctrls).
+
+The platform device driver exports a v4l2 radio device interface to user land.
+So, it uses the I2C device driver as a sub device in order to send the user
+commands to the actual device. Basically it is a wrapper to the I2C device driver.
+
+Applications can use v4l2 radio API to specify frequency of operation, mute state,
+etc. But mostly of its properties will be present in the extended controls.
+
+When the v4l2 mute property is set to 1 (true), the driver will turn the chip off.
+
+Properties description
+----------------------
+
+The properties can be accessed using v4l2 extended controls.

+RNL
+---
+
+This device also has an interface to measure received noise level. To do that, you should
+ioctl the device node. Here is an code of example:
+
+.. code-block:: none
+
+	int main (int argc, char *argv[])
+	{
+		struct si4713_rnl rnl;
+		int fd = open("/dev/radio0", O_RDWR);
+		int rval;
+
+		if (argc < 2)
+			return -EINVAL;
+
+		if (fd < 0)
+			return fd;
+
+		sscanf(argv[1], "%d", &rnl.frequency);
+
+		rval = ioctl(fd, SI4713_IOC_MEASURE_RNL, &rnl);
+		if (rval < 0)
+			return rval;
+
+		printf("received noise level: %d\n", rnl.rnl);
+
+		close(fd);
+	}
+
+The struct si4713_rnl and SI4713_IOC_MEASURE_RNL are defined under
+include/linux/platform_data/media/si4713.h.
+
+Stereo/Mono and RDS subchannels
+-------------------------------
+
+The device can also be configured using the available sub channels for
+transmission. To do that use S/G_MODULATOR ioctl and configure txsubchans properly.
+Refer to the V4L2 API specification for proper use of this ioctl.
+
+Testing
+-------
+Testing is usually done with v4l2-ctl utility for managing FM tuner cards.
+The tool can be found in v4l-dvb repository under v4l2-apps/util directory.
+
+Example for setting rds ps name:
+
+.. code-block:: none
+
+	# v4l2-ctl -d /dev/radio0 --set-ctrl=rds_ps_name="Dummy"

+The SI476x Driver
+=================
+
+Copyright |copy| 2013 Andrey Smirnov <andrew.smirnov@gmail.com>
+
+TODO for the driver
+-------------------
+
+- According to the SiLabs' datasheet it is possible to update the
+  firmware of the radio chip in the run-time, thus bringing it to the
+  most recent version. Unfortunately I couldn't find any mentioning of
+  the said firmware update for the old chips that I tested the driver
+  against, so for chips like that the driver only exposes the old
+  functionality.
+
+
+Parameters exposed over debugfs
+-------------------------------
+SI476x allow user to get multiple characteristics that can be very
+useful for EoL testing/RF performance estimation, parameters that have
+very little to do with V4L2 subsystem. Such parameters are exposed via
+debugfs and can be accessed via regular file I/O operations.
+
+The drivers exposes following files:
+
+* /sys/kernel/debug/<device-name>/acf
+  This file contains ACF(Automatically Controlled Features) status
+  information. The contents of the file is binary data of the
+  following layout:
+

+Infrared remote control support in video4linux drivers
+======================================================
+
+Authors: Gerd Hoffmann, Mauro Carvalho Chehab
+
+Basics
+------
+
+Most analog and digital TV boards support remote controllers. Several of
+them have a microprocessor that receives the IR carriers, convert into
+pulse/space sequences and then to scan codes, returning such codes to
+userspace ("scancode mode"). Other boards return just the pulse/space
+sequences ("raw mode").
+
+The support for remote controller in scancode mode is provided by the
+standard Linux input layer. The support for raw mode is provided via LIRC.
+
+In order to check the support and test it, it is suggested to download
+the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_. It provides
+two tools to handle remote controllers:
+
+- ir-keytable: provides a way to query the remote controller, list the
+  protocols it supports, enable in-kernel support for IR decoder or
+  switch the protocol and to test the reception of scan codes;
+
+- ir-ctl: provide tools to handle remote controllers that support raw mode
+  via LIRC interface.
+
+Usually, the remote controller module is auto-loaded when the TV card is
+detected. However, for a few devices, you need to manually load the
+ir-kbd-i2c module.
+
+How it works
+------------
+
+The modules register the remote as keyboard within the linux input
+layer, i.e. you'll see the keys of the remote as normal key strokes
+(if CONFIG_INPUT_KEYBOARD is enabled).
+
+Using the event devices (CONFIG_INPUT_EVDEV) it is possible for
+applications to access the remote via /dev/input/event<n> devices.
+The udev/systemd will automatically create the devices. If you install
+the `v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_, it may also
+automatically load a different keytable than the default one. Please see
+`v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ ir-keytable.1
+man page for details.
+
+The ir-keytable tool is nice for trouble shooting, i.e. to check
+whenever the input device is really present, which of the devices it
+is, check whenever pressing keys on the remote actually generates
+events and the like.  You can also use any other input utility that changes
+the keymaps, like the input kbd utility.
+
+
+Using with lircd
+================
+
+The latest versions of the lircd daemon supports reading events from the
+linux input layer (via event device). It also supports receiving IR codes
+in lirc mode.
+
+
+Using without lircd
+===================
+
+Xorg recognizes several IR keycodes that have its numerical value lower
+than 247. With the advent of Wayland, the input driver got updated too,
+and should now accept all keycodes. Yet, you may want to just reasign
+the keycodes to something that your favorite media application likes.
+
+This can be done by setting
+`v4l-utils <https://git.linuxtv.org/v4l-utils.git/>`_ to load your own
+keytable in runtime. Please read  ir-keytable.1 man page for details.

+CEC (Consumer Electronics Control)
+----------------------------------
+
+If there are HDMI inputs then a CEC adapter will be created that has
+the same number of input ports. This is the equivalent of e.g. a TV that
+has that number of inputs. Each HDMI output will also create a
+CEC adapter that is hooked up to the corresponding input port, or (if there
+are more outputs than inputs) is not hooked up at all. In other words,
+this is the equivalent of hooking up each output device to an input port of
+the TV. Any remaining output devices remain unconnected.
+
+The EDID that each output reads reports a unique CEC physical address that is
+based on the physical address of the EDID of the input. So if the EDID of the
+receiver has physical address A.B.0.0, then each output will see an EDID
+containing physical address A.B.C.0 where C is 1 to the number of inputs. If
+there are more outputs than inputs then the remaining outputs have a CEC adapter

+    kernel-include
+    ~~~~~~~~~~~~~~
+
+    Implementation of the ``kernel-include`` reST-directive.
+
+    :copyright:  Copyright (C) 2016  Markus Heiser
+    :license:    GPL Version 2, June 1991 see linux/COPYING for details.
+
+    The ``kernel-include`` reST-directive is a replacement for the ``include``
+    directive. The ``kernel-include`` directive expand environment variables in
+    the path name and allows to include files from arbitrary locations.
+
+    .. hint::
+
+      Including files from arbitrary locations (e.g. from ``/etc``) is a
+      security risk for builders. This is why the ``include`` directive from
+      docutils *prohibit* pathnames pointing to locations *above* the filesystem
+      tree where the reST document with the include directive is placed.
+
+    Substrings of the form $name or ${name} are replaced by the value of
+    environment variable name. Malformed variable names and references to
+    non-existing variables are left unchanged.

-1. Introduction
-
-	This is a driver for STMicroelectronics's CPiA2 (second generation
-Colour Processor Interface ASIC) based cameras. This camera outputs an MJPEG
-stream at up to vga size. It implements the Video4Linux interface as much as
-possible.  Since the V4L interface does not support compressed formats, only
-an mjpeg enabled application can be used with the camera. We have modified the
-gqcam application to view this stream.
-
-	The driver is implemented as two kernel modules. The cpia2 module
-contains the camera functions and the V4L interface.  The cpia2_usb module
-contains usb specific functions.  The main reason for this was the size of the
-module was getting out of hand, so I separated them.  It is not likely that
-there will be a parallel port version.
-
-FEATURES:
-   - Supports cameras with the Vision stv6410 (CIF) and stv6500 (VGA) cmos
-     sensors. I only have the vga sensor, so can't test the other.
-   - Image formats: VGA, QVGA, CIF, QCIF, and a number of sizes in between.
-     VGA and QVGA are the native image sizes for the VGA camera. CIF is done
-     in the coprocessor by scaling QVGA.  All other sizes are done by clipping.
-   - Palette: YCrCb, compressed with MJPEG.
-   - Some compression parameters are settable.
-   - Sensor framerate is adjustable (up to 30 fps CIF, 15 fps VGA).
-   - Adjust brightness, color, contrast while streaming.
-   - Flicker control settable for 50 or 60 Hz mains frequency.
-
-2. Making and installing the stv672 driver modules:
-
-	Requirements:
-	-------------
-	This should work with 2.4 (2.4.23 and later) and 2.6 kernels, but has
-only been tested on 2.6.  Video4Linux must be either compiled into the kernel or
-available as a module.  Video4Linux2 is automatically detected and made
-available at compile time.
-
-	Compiling:
-	----------
-	As root, do a make install.  This will compile and install the modules
-into the media/video directory in the module tree. For 2.4 kernels, use
-Makefile_2.4 (aka do make -f Makefile_2.4 install).
-
-	Setup:
-	------
-	Use 'modprobe cpia2' to load and 'modprobe -r cpia2' to unload. This
-may be done automatically by your distribution.
-
-3. Driver options
-
-	Option		Description
-	------		-----------
-	video_nr	video device to register (0=/dev/video0, etc)
-			range -1 to 64.  default is -1 (first available)
-			If you have more than 1 camera, this MUST be -1.
-	buffer_size	Size for each frame buffer in bytes (default 68k)
-	num_buffers	Number of frame buffers (1-32, default 3)
-	alternate	USB Alternate (2-7, default 7)
-	flicker_freq	Frequency for flicker reduction(50 or 60, default 60)
-	flicker_mode	0 to disable, or 1 to enable flicker reduction.
-			(default 0). This is only effective if the camera
-			uses a stv0672 coprocessor.
-
-	Setting the options:
-	--------------------
-	If you are using modules, edit /etc/modules.conf and add an options
-line like this:
-	options cpia2 num_buffers=3 buffer_size=65535
-
-	If the driver is compiled into the kernel, at boot time specify them
-like this:
-	cpia2.num_buffers=3 cpia2.buffer_size=65535
-
-	What buffer size should I use?
-	------------------------------
-	The maximum image size depends on the alternate you choose, and the
-frame rate achieved by the camera.  If the compression engine is able to
-keep up with the frame rate, the maximum image size is given by the table
-below.
-	The compression engine starts out at maximum compression, and will
-increase image quality until it is close to the size in the table.  As long
-as the compression engine can keep up with the frame rate, after a short time
-the images will all be about the size in the table, regardless of resolution.
-	At low alternate settings, the compression engine may not be able to
-compress the image enough and will reduce the frame rate by producing larger
-images.
-	The default of 68k should be good for most users.  This will handle
-any alternate at frame rates down to 15fps.  For lower frame rates, it may
-be necessary to increase the buffer size to avoid having frames dropped due
-to insufficient space.
-
-			     Image size(bytes)
-	Alternate  bytes/ms   15fps    30fps
-	    2         128      8533     4267
-	    3         384     25600    12800
-	    4         640     42667    21333
-	    5         768     51200    25600
-	    6         896     59733    29867
-	    7        1023     68200    34100
-
-	How many buffers should I use?
-	------------------------------
-	For normal streaming, 3 should give the best results.  With only 2,
-it is possible for the camera to finish sending one image just after a
-program has started reading the other.  If this happens, the driver must drop
-a frame.  The exception to this is if you have a heavily loaded machine.  In
-this case use 2 buffers.  You are probably not reading at the full frame rate.
-If the camera can send multiple images before a read finishes, it could
-overwrite the third buffer before the read finishes, leading to a corrupt
-image.  Single and double buffering have extra checks to avoid overwriting.
-
-4. Using the camera

-	We are providing a modified gqcam application to view the output. In
-order to avoid confusion, here it is called mview.  There is also the qx5view
-program which can also control the lights on the qx5 microscope. MJPEG Tools
-(http://mjpeg.sourceforge.net) can also be used to record from the camera.
-
-5. Notes to developers:
-
-   - This is a driver version stripped of the 2.4 back compatibility
-     and old MJPEG ioctl API. See cpia2.sf.net for 2.4 support.
-
-6. Thanks:

-   - Peter Pregler <Peter_Pregler@email.com>,
-     Scott J. Bertin <scottbertin@yahoo.com>, and
-     Jarl Totland <Jarl.Totland@bdc.no> for the original cpia driver, which
-     this one was modelled from.

-cx8800 release notes
-====================
-
-This is a v4l2 device driver for the cx2388x chip.
-
-
-current status
-==============
-
-video
-	- Basically works.
-	- For now, only capture and read(). Overlay isn't supported.
-
-audio
-	- The chip specs for the on-chip TV sound decoder are next
-	  to useless :-/
-	- Neverless the builtin TV sound decoder starts working now,
-	  at least for some standards.
-	  FOR ANY REPORTS ON THIS PLEASE MENTION THE TV NORM YOU ARE
-	  USING.
-	- Most tuner chips do provide mono sound, which may or may not
-	  be useable depending on the board design.  With the Hauppauge
-	  cards it works, so there is mono sound available as fallback.
-	- audio data dma (i.e. recording without loopback cable to the
-	  sound card) is supported via cx88-alsa.
-
-vbi
-	- Code present. Works for NTSC closed caption. PAL and other
-	  TV norms may or may not work.
-
-
-how to add support for new cards
-================================
-
-The driver needs some config info for the TV cards.  This stuff is in
-cx88-cards.c.  If the driver doesn't work well you likely need a new
-entry for your card in that file.  Check the kernel log (using dmesg)
-to see whenever the driver knows your card or not.  There is a line
-like this one:
-
-	cx8800[0]: subsystem: 0070:3400, board: Hauppauge WinTV \
-		34xxx models [card=1,autodetected]
-
-If your card is listed as "board: UNKNOWN/GENERIC" it is unknown to
-the driver.  What to do then?
-
- (1) Try upgrading to the latest snapshot, maybe it has been added
-     meanwhile.
- (2) You can try to create a new entry yourself, have a look at
-     cx88-cards.c.  If that worked, mail me your changes as unified
-     diff ("diff -u").
- (3) Or you can mail me the config information.  I need at least the
-     following information to add the card:
-
-     * the PCI Subsystem ID ("0070:3400" from the line above,
-       "lspci -v" output is fine too).
-     * the tuner type used by the card.  You can try to find one by
-       trial-and-error using the tuner=<n> insmod option.  If you
-       know which one the card has you can also have a look at the
-       list in CARDLIST.tuner
-
-Have fun,
-
-  Gerd

-infrared remote control support in video4linux drivers
-======================================================
-
-
-basics
-------
-
-Current versions use the linux input layer to support infrared
-remote controls.  I suggest to download my input layer tools
-from http://bytesex.org/snapshot/input-<date>.tar.gz
-
-Modules you have to load:
-
-  saa7134	statically built in, i.e. just the driver :)
-  bttv		ir-kbd-gpio or ir-kbd-i2c depending on your
-		card.
-
-ir-kbd-gpio and ir-kbd-i2c don't support all cards lirc supports
-(yet), mainly for the reason that the code of lirc_i2c and lirc_gpio
-was very confusing and I decided to basically start over from scratch.
-Feel free to contact me in case of trouble.  Note that the ir-kbd-*
-modules work on 2.6.x kernels only through ...
-
-
-how it works
-------------
-
-The modules register the remote as keyboard within the linux input
-layer, i.e. you'll see the keys of the remote as normal key strokes
-(if CONFIG_INPUT_KEYBOARD is enabled).
-
-Using the event devices (CONFIG_INPUT_EVDEV) it is possible for
-applications to access the remote via /dev/input/event<n> devices.
-You might have to create the special files using "/sbin/MAKEDEV
-input".  The input layer tools mentioned above use the event device.
-
-The input layer tools are nice for trouble shooting, i.e. to check
-whenever the input device is really present, which of the devices it
-is, check whenever pressing keys on the remote actually generates
-events and the like.  You can also use the kbd utility to change the
-keymaps (2.6.x kernels only through).
-
-
-using with lircd
-================
-
-The cvs version of the lircd daemon supports reading events from the
-linux input layer (via event device).  The input layer tools tarball
-comes with a lircd config file.
-
-
-using without lircd
-===================
-
-XFree86 likely can be configured to recognise the remote keys.  Once I
-simply tried to configure one of the multimedia keyboards as input
-device, which had the effect that XFree86 recognised some of the keys
-of my remote control and passed volume up/down key presses as
-XF86AudioRaiseVolume and XF86AudioLowerVolume key events to the X11
-clients.
-
-It likely is possible to make that fly with a nice xkb config file,
-I know next to nothing about that through.
-
-
-Have fun,
-
-  Gerd

-ivtv release notes
-==================
-
-This is a v4l2 device driver for the Conexant cx23415/6 MPEG encoder/decoder.
-The cx23415 can do both encoding and decoding, the cx23416 can only do MPEG
-encoding. Currently the only card featuring full decoding support is the
-Hauppauge PVR-350.
-
-NOTE: this driver requires the latest encoder firmware (version 2.06.039, size
-376836 bytes). Get the firmware from here:
-
-http://dl.ivtvdriver.org/ivtv/firmware/
-
-NOTE: 'normal' TV applications do not work with this driver, you need
-an application that can handle MPEG input such as mplayer, xine, MythTV,
-etc.
-
-The primary goal of the IVTV project is to provide a "clean room" Linux
-Open Source driver implementation for video capture cards based on the
-iCompression iTVC15 or Conexant CX23415/CX23416 MPEG Codec.
-
-Features:
- * Hardware mpeg2 capture of broadcast video (and sound) via the tuner or
-   S-Video/Composite and audio line-in.
- * Hardware mpeg2 capture of FM radio where hardware support exists
- * Supports NTSC, PAL, SECAM with stereo sound
- * Supports SAP and bilingual transmissions.
- * Supports raw VBI (closed captions and teletext).
- * Supports sliced VBI (closed captions and teletext) and is able to insert
-   this into the captured MPEG stream.
- * Supports raw YUV and PCM input.
-
-Additional features for the PVR-350 (CX23415 based):
- * Provides hardware mpeg2 playback
- * Provides comprehensive OSD (On Screen Display: ie. graphics overlaying the
-   video signal)
- * Provides a framebuffer (allowing X applications to appear on the video
-   device)
- * Supports raw YUV output.
-
-IMPORTANT: In case of problems first read this page:
-	   http://www.ivtvdriver.org/index.php/Troubleshooting
-

-
-----------------------------------------------------------
-
-Devices
-=======
-
-A maximum of 12 ivtv boards are allowed at the moment.
-
-Cards that don't have a video output capability (i.e. non PVR350 cards)
-lack the vbi8, vbi16, video16 and video48 devices. They also do not
-support the framebuffer device /dev/fbx for OSD.
-
-The radio0 device may or may not be present, depending on whether the
-card has a radio tuner or not.
-
-Here is a list of the base v4l devices:
-crw-rw----    1 root     video     81,   0 Jun 19 22:22 /dev/video0
-crw-rw----    1 root     video     81,  16 Jun 19 22:22 /dev/video16
-crw-rw----    1 root     video     81,  24 Jun 19 22:22 /dev/video24
-crw-rw----    1 root     video     81,  32 Jun 19 22:22 /dev/video32
-crw-rw----    1 root     video     81,  48 Jun 19 22:22 /dev/video48
-crw-rw----    1 root     video     81,  64 Jun 19 22:22 /dev/radio0
-crw-rw----    1 root     video     81, 224 Jun 19 22:22 /dev/vbi0
-crw-rw----    1 root     video     81, 228 Jun 19 22:22 /dev/vbi8
-crw-rw----    1 root     video     81, 232 Jun 19 22:22 /dev/vbi16
-
-Base devices
-============
-
-For every extra card you have the numbers increased by one. For example,
-/dev/video0 is listed as the 'base' encoding capture device so we have:
-
- /dev/video0  is the encoding capture device for the first card (card 0)
- /dev/video1  is the encoding capture device for the second card (card 1)
- /dev/video2  is the encoding capture device for the third card (card 2)
-
-Note that if the first card doesn't have a feature (eg no decoder, so no
-video16, the second card will still use video17. The simple rule is 'add
-the card number to the base device number'. If you have other capture
-cards (e.g. WinTV PCI) that are detected first, then you have to tell
-the ivtv module about it so that it will start counting at 1 (or 2, or
-whatever). Otherwise the device numbers can get confusing. The ivtv
-'ivtv_first_minor' module option can be used for that.
-
-
-/dev/video0
-The encoding capture device(s).
-Read-only.
-
-Reading from this device gets you the MPEG1/2 program stream.
-Example:
-
-cat /dev/video0 > my.mpg (you need to hit ctrl-c to exit)
-
-
-/dev/video16
-The decoder output device(s)
-Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
-
-An mpeg2 stream sent to this device will appear on the selected video
-display, audio will appear on the line-out/audio out.  It is only
-available for cards that support video out. Example:
-
-cat my.mpg >/dev/video16
-
-
-/dev/video24
-The raw audio capture device(s).
-Read-only
-
-The raw audio PCM stereo stream from the currently selected
-tuner or audio line-in.  Reading from this device results in a raw
-(signed 16 bit Little Endian, 48000 Hz, stereo pcm) capture.
-This device only captures audio. This should be replaced by an ALSA
-device in the future.
-Note that there is no corresponding raw audio output device, this is
-not supported in the decoder firmware.
-
-
-/dev/video32
-The raw video capture device(s)
-Read-only
-
-The raw YUV video output from the current video input. The YUV format
-is non-standard (V4L2_PIX_FMT_HM12).
-
-Note that the YUV and PCM streams are not synchronized, so they are of
-limited use.
-
-
-/dev/video48
-The raw video display device(s)
-Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
-
-Writes a YUV stream to the decoder of the card.
-
-
-/dev/radio0
-The radio tuner device(s)
-Cannot be read or written.
-
-Used to enable the radio tuner and tune to a frequency. You cannot
-read or write audio streams with this device.  Once you use this
-device to tune the radio, use /dev/video24 to read the raw pcm stream
-or /dev/video0 to get an mpeg2 stream with black video.
-
-
-/dev/vbi0
-The 'vertical blank interval' (Teletext, CC, WSS etc) capture device(s)
-Read-only
-
-Captures the raw (or sliced) video data sent during the Vertical Blank
-Interval. This data is used to encode teletext, closed captions, VPS,
-widescreen signalling, electronic program guide information, and other
-services.
-
-
-/dev/vbi8
-Processed vbi feedback device(s)
-Read-only. Only present if the MPEG decoder (i.e. CX23415) exists.
-
-The sliced VBI data embedded in an MPEG stream is reproduced on this
-device. So while playing back a recording on /dev/video16, you can
-read the embedded VBI data from /dev/vbi8.
-
-
-/dev/vbi16
-The vbi 'display' device(s)
-Write-only. Only present if the MPEG decoder (i.e. CX23415) exists.
-
-Can be used to send sliced VBI data to the video-out connector.

-What is it?
-===========
-
-This is a v4l2/oss device driver for saa7130/33/34/35 based capture / TV
-boards.  See http://www.semiconductors.philips.com/pip/saa7134hl for a
-description.
-
-
-Status
-======
-
-Almost everything is working.  video, sound, tuner, radio, mpeg ts, ...
-
-As with bttv, card-specific tweaks are needed.  Check CARDLIST for a
-list of known TV cards and saa7134-cards.c for the drivers card
-configuration info.
-
-
-Build
-=====
-
-Pick up videodev + v4l2 patches from http://bytesex.org/patches/.
-Configure, build, install + boot the new kernel.  You'll need at least
-these config options:
-
-	CONFIG_I2C=m
-	CONFIG_VIDEO_DEV=m
-
-Type "make" to build the driver now.  "make install" installs the
-driver.  "modprobe saa7134" should load it.  Depending on the card you
-might have to pass card=<nr> as insmod option, check CARDLIST for
-valid choices.
-
-
-Changes / Fixes
-===============
-
-Please mail me unified diffs ("diff -u") with your changes, and don't
-forget to tell me what it changes / which problem it fixes / whatever
-it is good for ...
-
-
-Known Problems
-==============
-
-* The tuner for the flyvideos isn't detected automatically and the
-  default might not work for you depending on which version you have.
-  There is a tuner= insmod option to override the driver's default.
-
-Card Variations:
-================
-
-Cards can use either of these two crystals (xtal):
- - 32.11 MHz -> .audio_clock=0x187de7
- - 24.576MHz -> .audio_clock=0x200000
-(xtal * .audio_clock = 51539600)
-
-Some details about 30/34/35:
-
- - saa7130 - low-price chip, doesn't have mute, that is why all those
- cards should have .mute field defined in their tuner structure.
-
- - saa7134 - usual chip
-
- - saa7133/35 - saa7135 is probably a marketing decision, since all those
- chips identifies itself as 33 on pci.
-

-Developed by TelSignal(?), OEMed by many vendors (Typhoon, Anubis, Dynalink)
-
-  Card series:
-    CPH01x: BT848 capture only
-    CPH03x: BT848
-    CPH05x: BT878 with FM
-    CPH06x: BT878 (w/o FM)
-    CPH07x: BT878 capture only
-
-  TV standards:
-     CPH0x0: NTSC-M/M
-     CPH0x1: PAL-B/G

-
-  CPH03x was often sold as "TV capturer".
-
-  Identifying:
-  1) 878 cards can be identified by PCI Subsystem-ID:
-      144f:3000 = CPH06x
-      144F:3002 = CPH05x w/ FM
-      144F:3005 = CPH06x_LC (w/o remote control)
-  1) The cards have a sticker with "CPH"-model on the back.
-  2) These cards have a number printed on the PCB just above the tuner metal box:
-      "80-CP2000300-x" = CPH03X
-      "80-CP2000500-x" = CPH05X
-      "80-CP2000600-x" = CPH06X / CPH06x_LC
-
-  Askey sells these cards as "Magic TView series", Brand "MagicXpress".
-  Other OEM often call these "Tview", "TView99" or else.
-
-Lifeview Flyvideo Series:
--------------------------
-  The naming of these series differs in time and space.
-
-  Identifying:
-  1) Some models can be identified by PCI subsystem ID:
-      1852:1852 = Flyvideo 98 FM
-      1851:1850 = Flyvideo 98
-      1851:1851 = Flyvideo 98 EZ (capture only)
-  2) There is a print on the PCB:
-      LR25       = Flyvideo (Zoran ZR36120, SAA7110A)
-      LR26 Rev.N = Flyvideo II (Bt848)
-	   Rev.O = Flyvideo II (Bt878)
-      LR37 Rev.C = Flyvideo EZ (Capture only, ZR36120 + SAA7110)
-      LR38 Rev.A1= Flyvideo II EZ (Bt848 capture only)
-      LR50 Rev.Q = Flyvideo 98 (w/eeprom and PCI subsystem ID)
-	   Rev.W = Flyvideo 98 (no eeprom)
-      LR51 Rev.E = Flyvideo 98 EZ (capture only)

-Note: "modinfo <module>" prints various information about a kernel
-module, among them a complete and up-to-date list of insmod options.
-This list tends to be outdated because it is updated manually ...
-
-==========================================================================
-
-bttv.o
-	the bt848/878 (grabber chip) driver
-
-	insmod args:
-		card=n		card type, see CARDLIST for a list.
-		tuner=n		tuner type, see CARDLIST for a list.
-		radio=0/1	card supports radio
-		pll=0/1/2	pll settings
-			0: don't use PLL
-			1: 28 MHz crystal installed
-			2: 35 MHz crystal installed
-
-		triton1=0/1     for Triton1 (+others) compatibility
-		vsfx=0/1	yet another chipset bug compatibility bit
-				see README.quirks for details on these two.
-
-		bigendian=n	Set the endianness of the gfx framebuffer.
-				Default is native endian.
-		fieldnr=0/1	Count fields.  Some TV descrambling software
-				needs this, for others it only generates
-				50 useless IRQs/sec.  default is 0 (off).
-		autoload=0/1	autoload helper modules (tuner, audio).
-				default is 1 (on).
-		bttv_verbose=0/1/2  verbose level (at insmod time, while
-				looking at the hardware).  default is 1.
-		bttv_debug=0/1	debug messages (for capture).
-				default is 0 (off).
-		irq_debug=0/1	irq handler debug messages.
-				default is 0 (off).
-		gbuffers=2-32	number of capture buffers for mmap'ed capture.
-				default is 4.
-		gbufsize=	size of capture buffers. default and
-				maximum value is 0x208000 (~2MB)
-		no_overlay=0	Enable overlay on broken hardware.  There
-				are some chipsets (SIS for example) which
-				are known to have problems with the PCI DMA
-				push used by bttv.  bttv will disable overlay
-				by default on this hardware to avoid crashes.
-				With this insmod option you can override this.
-		no_overlay=1	Disable overlay. It should be used by broken
-				hardware that doesn't support PCI2PCI direct
-				transfers.
-		automute=0/1	Automatically mutes the sound if there is
-				no TV signal, on by default.  You might try
-				to disable this if you have bad input signal
-				quality which leading to unwanted sound
-				dropouts.
-		chroma_agc=0/1	AGC of chroma signal, off by default.
-		adc_crush=0/1	Luminance ADC crush, on by default.
-		i2c_udelay=     Allow reduce I2C speed. Default is 5 usecs
-				(meaning 66,67 Kbps). The default is the
-				maximum supported speed by kernel bitbang
-				algorithm. You may use lower numbers, if I2C
-				messages are lost (16 is known to work on
-				all supported cards).
-
-		bttv_gpio=0/1
-		gpiomask=
-		audioall=
-		audiomux=
-				See Sound-FAQ for a detailed description.
-
-	remap, card, radio and pll accept up to four comma-separated arguments
-	(for multiple boards).
-
-tuner.o
-	The tuner driver.  You need this unless you want to use only
-	with a camera or external tuner ...
-
-	insmod args:
-		debug=1		print some debug info to the syslog
-		type=n		type of the tuner chip. n as follows:
-				see CARDLIST for a complete list.
-		pal=[bdgil]	select PAL variant (used for some tuners
-				only, important for the audio carrier).
-
-tvaudio.o
-	new, experimental module which is supported to provide a single
-	driver for all simple i2c audio control chips (tda/tea*).
-
-	insmod args:
-		tda8425  = 1	enable/disable the support for the
-		tda9840  = 1	various chips.
-		tda9850  = 1	The tea6300 can't be autodetected and is
-		tda9855  = 1	therefore off by default, if you have
-		tda9873  = 1	this one on your card (STB uses these)
-		tda9874a = 1	you have to enable it explicitly.
-		tea6300  = 0	The two tda985x chips use the same i2c
-		tea6420  = 1	address and can't be disturgished from
-		pic16c54 = 1	each other, you might have to disable
-				the wrong one.
-		debug = 1	print debug messages
-
-	insmod args for tda9874a:
-		tda9874a_SIF=1/2	select sound IF input pin (1 or 2)
-					(default is pin 1)
-		tda9874a_AMSEL=0/1	auto-mute select for NICAM (default=0)
-					Please read note 3 below!
-		tda9874a_STD=n		select TV sound standard (0..8):
-					0 - A2, B/G
-					1 - A2, M (Korea)
-					2 - A2, D/K (1)
-					3 - A2, D/K (2)
-					4 - A2, D/K (3)
-					5 - NICAM, I
-					6 - NICAM, B/G
-					7 - NICAM, D/K (default)
-					8 - NICAM, L
-
-	Note 1: tda9874a supports both tda9874h (old) and tda9874a (new) chips.
-	Note 2: tda9874h/a and tda9875 (which is supported separately by
-	tda9875.o) use the same i2c address so both modules should not be
-	used at the same time.
-	Note 3: Using tda9874a_AMSEL option depends on your TV card design!
-		AMSEL=0: auto-mute will switch between NICAM sound
-			 and the sound on 1st carrier (i.e. FM mono or AM).
-		AMSEL=1: auto-mute will switch between NICAM sound
-			 and the analog mono input (MONOIN pin).
-	If tda9874a decoder on your card has MONOIN pin not connected, then
-	use only tda9874_AMSEL=0 or don't specify this option at all.
-	For example:
-	  card=65 (FlyVideo 2000S) - set AMSEL=1 or AMSEL=0
-	  card=72 (Prolink PV-BT878P rev.9B) - set AMSEL=0 only
-
-msp3400.o
-	The driver for the msp34xx sound processor chips. If you have a
-	stereo card, you probably want to insmod this one.
-
-	insmod args:
-		debug=1/2	print some debug info to the syslog,
-				2 is more verbose.
-		simple=1	Use the "short programming" method.  Newer
-				msp34xx versions support this.  You need this
-				for dbx stereo.  Default is on if supported by
-				the chip.
-		once=1		Don't check the TV-stations Audio mode
-				every few seconds, but only once after
-				channel switches.
-		amsound=1	Audio carrier is AM/NICAM at 6.5 Mhz.  This
-				should improve things for french people, the
-				carrier autoscan seems to work with FM only...
-
-tea6300.o - OBSOLETE (use tvaudio instead)
-	The driver for the tea6300 fader chip.  If you have a stereo
-	card and the msp3400.o doesn't work, you might want to try this
-	one.  This chip is seen on most STB TV/FM cards (usually from
-	Gateway OEM sold surplus on auction sites).
-
-	insmod args:
-		debug=1		print some debug info to the syslog.
-
-tda8425.o - OBSOLETE (use tvaudio instead)
-	The driver for the tda8425 fader chip.  This driver used to be
-	part of bttv.c, so if your sound used to work but does not
-	anymore, try loading this module.
-
-	insmod args:
-		debug=1		print some debug info to the syslog.
-
-tda985x.o - OBSOLETE (use tvaudio instead)
-	The driver for the tda9850/55 audio chips.
-
-	insmod args:
-		debug=1		print some debug info to the syslog.
-		chip=9850/9855	set the chip type.

-- The memory of some S3 cards is not recognized right:
-
-  First of all, if you are not using XFree-3.2 or newer, upgrade AT LEAST to
-  XFree-3.2A! This solved the problem for most people.
-
-  Start up X11 like this: "XF86_S3 -probeonly" and write down where the
-  linear frame buffer is.
-  If it is different to the address found by bttv install bttv like this:
-  "insmod bttv vidmem=0xfb0"
-  if the linear frame buffer is at 0xfb000000 (i.e. omit the last 5 zeros!)
-
-  Some S3 cards even take up 64MB of memory but only report 32MB to the BIOS.
-  If this 64MB area overlaps the IO memory of the Bt848 you also have to
-  remap this. E.g.: insmod bttv vidmem=0xfb0 remap=0xfa0
-
-  If the video memory is found at the right place and there are no address
-  conflicts but still no picture (or the computer even crashes),
-  try disabling features of your PCI chipset in the BIOS setup.
-
-  Frank Kapahnke <frank@kapahnke.prima.ruhr.de> also reported that problems
-  with his S3 868 went away when he upgraded to XFree 3.2.
-
-
-- I still only get a black picture with my S3 card!
-
-  Even with XFree-3.2A some people have problems with their S3 cards
-  (mostly with Trio 64 but also with some others)
-  Get the free demo version of Accelerated X from www.xinside.com and try
-  bttv with it. bttv seems to work with most S3 cards with Accelerated X.
-
-  Since I do not know much (better make that almost nothing) about VGA card
-  programming I do not know the reason for this.
-  Looks like XFree does something different when setting up the video memory?
-  Maybe somebody can enlighten me?
-  Would be nice if somebody could get this to work with XFree since
-  Accelerated X costs more than some of the grabber cards ...
-
-  Better linear frame buffer support for S3 cards will probably be in
-  XFree 4.0.
-
-- Grabbing is not switched off when changing consoles with XFree.
-  That's because XFree and some AcceleratedX versions do not send unmap
-  events.
-
-- Some popup windows (e.g. of the window manager) are not refreshed.
-
-  Disable backing store by starting X with the option "-bs"
-
-- When using 32 bpp in XFree or 24+8bpp mode in AccelX 3.1 the system
-  can sometimes lock up if you use more than 1 bt848 card at the same time.
-  You will always get pixel errors when e.g. using more than 1 card in full
-  screen mode. Maybe we need something faster than the PCI bus ...
-
-
-- Some S3 cards and the Matrox Mystique will produce pixel errors with
-  full resolution in 32-bit mode.
-
-- Some video cards have problems with Accelerated X 4.1

-Release notes for bttv
-======================
-
-You'll need at least these config options for bttv:
-	CONFIG_I2C=m
-	CONFIG_I2C_ALGOBIT=m
-	CONFIG_VIDEO_DEV=m
-
-The latest bttv version is available from http://bytesex.org/bttv/
-
-
-Make bttv work with your card
------------------------------
-
-Just try "modprobe bttv" and see if that works.
-
-If it doesn't bttv likely could not autodetect your card and needs some
-insmod options.  The most important insmod option for bttv is "card=n"
-to select the correct card type.  If you get video but no sound you've
-very likely specified the wrong (or no) card type.  A list of supported
-cards is in CARDLIST.bttv
-
-If bttv takes very long to load (happens sometimes with the cheap
-cards which have no tuner), try adding this to your modules.conf:
-	options i2c-algo-bit bit_test=1
-
-For the WinTV/PVR you need one firmware file from the driver CD:
-hcwamc.rbf.  The file is in the pvr45xxx.exe archive (self-extracting
-zip file, unzip can unpack it).  Put it into the /etc/pvr directory or
-use the firm_altera=<path> insmod option to point the driver to the
-location of the file.
-
-If your card isn't listed in CARDLIST.bttv or if you have trouble making
-audio work, you should read the Sound-FAQ.
-
-
-Autodetecting cards
--------------------
-
-bttv uses the PCI Subsystem ID to autodetect the card type.  lspci lists
-the Subsystem ID in the second line, looks like this:
-
-00:0a.0 Multimedia video controller: Brooktree Corporation Bt878 (rev 02)
-	Subsystem: Hauppauge computer works Inc. WinTV/GO
-	Flags: bus master, medium devsel, latency 32, IRQ 5
-	Memory at e2000000 (32-bit, prefetchable) [size=4K]
-
-only bt878-based cards can have a subsystem ID (which does not mean
-that every card really has one).  bt848 cards can't have a Subsystem
-ID and therefore can't be autodetected.  There is a list with the ID's
-in bttv-cards.c (in case you are intrested or want to mail patches
-with updates).
-
-
-Still doesn't work?
--------------------
-
-I do NOT have a lab with 30+ different grabber boards and a
-PAL/NTSC/SECAM test signal generator at home, so I often can't
-reproduce your problems.  This makes debugging very difficult for me.
-If you have some knowledge and spare time, please try to fix this
-yourself (patches very welcome of course...)  You know: The linux
-slogan is "Do it yourself".
-
-There is a mailing list: linux-media@vger.kernel.org
-http://vger.kernel.org/vger-lists.html#linux-media
-
-If you have trouble with some specific TV card, try to ask there
-instead of mailing me directly.  The chance that someone with the
-same card listens there is much higher...
-
-For problems with sound:  There are a lot of different systems used
-for TV sound all over the world.  And there are also different chips
-which decode the audio signal.  Reports about sound problems ("stereo
-does'nt work") are pretty useless unless you include some details
-about your hardware and the TV sound scheme used in your country (or
-at least the country you are living in).
-
-
-Finally: If you mail some patches for bttv around the world (to
-linux-kernel/Alan/Linus/...), please Cc: me.
-
-
-Have fun with bttv,
-
-  Gerd

-Support for the Leadtek WinView 601 TV/FM by Jon Tombs <jon@gte.esi.us.es>
-
-This card is basically the same as all the rest (Bt484A, Philips tuner),
-the main difference is that they have attached a programmable attenuator to 3
-GPIO lines in order to give some volume control. They have also stuck an
-infra-red remote control decoded on the board, I will add support for this
-when I get time (it simple generates an interrupt for each key press, with
-the key code is placed in the GPIO port).
-
-I don't yet have any application to test the radio support. The tuner
-frequency setting should work but it is possible that the audio multiplexer
-is wrong. If it doesn't work, send me email.
-
-
-- No Thanks to Leadtek they refused to answer any questions about their
-hardware. The driver was written by visual inspection of the card. If you
-use this driver, send an email insult to them, and tell them you won't
-continue buying their hardware unless they support Linux.
-
-- Little thanks to Princeton Technology Corp (http://www.princeton.com.tw)
-who make the audio attenuator. Their publicly available data-sheet available
-on their web site doesn't include the chip programming information! Hidden
-on their server are the full data-sheets, but don't ask how I found it.
-
-To use the driver I use the following options, the tuner and pll settings might
-be different in your country

-insmod tuner type=1 debug=0

-If the box freezes hard with bttv ...
-=====================================
-
-It might be a bttv driver bug.  It also might be bad hardware.  It also
-might be something else ...
-
-Just mailing me "bttv freezes" isn't going to help much.  This README
-has a few hints how you can help to pin down the problem.
-
-
-bttv bugs
----------
-
-If some version works and another doesn't it is likely to be a driver
-bug.  It is very helpful if you can tell where exactly it broke
-(i.e. the last working and the first broken version).
-
-With a hard freeze you probably doesn't find anything in the logfiles.
-The only way to capture any kernel messages is to hook up a serial
-console and let some terminal application log the messages.  /me uses
-screen.  See Documentation/serial-console.txt for details on setting
-up a serial console.
-
-Read Documentation/oops-tracing.txt to learn how to get any useful
-information out of a register+stack dump printed by the kernel on
-protection faults (so-called "kernel oops").
-
-If you run into some kind of deadlock, you can try to dump a call trace
-for each process using sysrq-t (see Documentation/sysrq.txt).
-This way it is possible to figure where *exactly* some process in "D"
-state is stuck.
-
-I've seen reports that bttv 0.7.x crashes whereas 0.8.x works rock solid
-for some people.  Thus probably a small buglet left somewhere in bttv
-0.7.x.  I have no idea where exactly, it works stable for me and a lot of
-other people.  But in case you have problems with the 0.7.x versions you
-can give 0.8.x a try ...
-
-
-hardware bugs
--------------
-
-Some hardware can't deal with PCI-PCI transfers (i.e. grabber => vga).
-Sometimes problems show up with bttv just because of the high load on
-the PCI bus. The bt848/878 chips have a few workarounds for known
-incompatibilities, see README.quirks.
-
-Some folks report that increasing the pci latency helps too,
-althrought I'm not sure whenever this really fixes the problems or
-only makes it less likely to happen.  Both bttv and btaudio have a
-insmod option to set the PCI latency of the device.
-
-Some mainboard have problems to deal correctly with multiple devices
-doing DMA at the same time.  bttv + ide seems to cause this sometimes,
-if this is the case you likely see freezes only with video and hard disk
-access at the same time.  Updating the IDE driver to get the latest and
-greatest workarounds for hardware bugs might fix these problems.
-
-
-other
------
-
-If you use some binary-only yunk (like nvidia module) try to reproduce
-the problem without.
-
-IRQ sharing is known to cause problems in some cases.  It works just
-fine in theory and many configurations.  Neverless it might be worth a
-try to shuffle around the PCI cards to give bttv another IRQ or make
-it share the IRQ with some other piece of hardware.  IRQ sharing with
-VGA cards seems to cause trouble sometimes.  I've also seen funny
-effects with bttv sharing the IRQ with the ACPI bridge (and
-apci-enabled kernel).

-Below is what the bt878 data book says about the PCI bug compatibility
-modes of the bt878 chip.

-The triton1 insmod option sets the EN_TBFX bit in the control register.

-
-Normal PCI Mode
----------------
-
-The PCI REQ signal is the logical-or of the incoming function requests.
-The inter-nal GNT[0:1] signals are gated asynchronously with GNT and
-demultiplexed by the audio request signal. Thus the arbiter defaults to
-the video function at power-up and parks there during no requests for
-bus access. This is desirable since the video will request the bus more
-often. However, the audio will have highest bus access priority. Thus
-the audio will have first access to the bus even when issuing a request
-after the video request but before the PCI external arbiter has granted
-access to the Bt879. Neither function can preempt the other once on the
-bus. The duration to empty the entire video PCI FIFO onto the PCI bus is
-very short compared to the bus access latency the audio PCI FIFO can
-tolerate.
-
-
-430FX Compatibility Mode
-------------------------
-
-When using the 430FX PCI, the following rules will ensure
-compatibility:
-
- (1) Deassert REQ at the same time as asserting FRAME.
- (2) Do not reassert REQ to request another bus transaction until after
-     finish-ing the previous transaction.
-
-Since the individual bus masters do not have direct control of REQ, a
-simple logical-or of video and audio requests would violate the rules.
-Thus, both the arbiter and the initiator contain 430FX compatibility
-mode logic. To enable 430FX mode, set the EN_TBFX bit as indicated in
-Device Control Register on page 104.
-
-When EN_TBFX is enabled, the arbiter ensures that the two compatibility
-rules are satisfied. Before GNT is asserted by the PCI arbiter, this
-internal arbiter may still logical-or the two requests. However, once
-the GNT is issued, this arbiter must lock in its decision and now route
-only the granted request to the REQ pin. The arbiter decision lock
-happens regardless of the state of FRAME because it does not know when
-FRAME will be asserted (typically - each initiator will assert FRAME on
-the cycle following GNT). When FRAME is asserted, it is the initiator s
-responsibility to remove its request at the same time. It is the
-arbiters responsibility to allow this request to flow through to REQ and
-not allow the other request to hold REQ asserted. The decision lock may
-be removed at the end of the transaction: for example, when the bus is
-idle (FRAME and IRDY). The arbiter decision may then continue
-asynchronously until GNT is again asserted.
-
-
-Interfacing with Non-PCI 2.1 Compliant Core Logic
--------------------------------------------------
-
-A small percentage of core logic devices may start a bus transaction
-during the same cycle that GNT is de-asserted. This is non PCI 2.1
-compliant. To ensure compatibility when using PCs with these PCI
-controllers, the EN_VSFX bit must be enabled (refer to Device Control
-Register on page 104). When in this mode, the arbiter does not pass GNT
-to the internal functions unless REQ is asserted. This prevents a bus
-transaction from starting the same cycle as GNT is de-asserted. This
-also has the side effect of not being able to take advantage of bus
-parking, thus lowering arbitration performance. The Bt879 drivers must
-query for these non-compliant devices, and set the EN_VSFX bit only if
-required.

-bttv and sound mini howto
-=========================
-
-There are a lot of different bt848/849/878/879 based boards available.
-Making video work often is not a big deal, because this is handled
-completely by the bt8xx chip, which is common on all boards.  But
-sound is handled in slightly different ways on each board.
-
-To handle the grabber boards correctly, there is a array tvcards[] in
-bttv-cards.c, which holds the information required for each board.
-Sound will work only, if the correct entry is used (for video it often
-makes no difference).  The bttv driver prints a line to the kernel
-log, telling which card type is used.  Like this one:
-
-	bttv0: model: BT848(Hauppauge old) [autodetected]
-
-You should verify this is correct.  If it isn't, you have to pass the
-correct board type as insmod argument, "insmod bttv card=2" for
-example.  The file CARDLIST has a list of valid arguments for card.
-If your card isn't listed there, you might check the source code for
-new entries which are not listed yet.  If there isn't one for your
-card, you can check if one of the existing entries does work for you
-(just trial and error...).
-
-Some boards have an extra processor for sound to do stereo decoding
-and other nice features.  The msp34xx chips are used by Hauppauge for
-example.  If your board has one, you might have to load a helper
-module like msp3400.o to make sound work.  If there isn't one for the
-chip used on your board:  Bad luck.  Start writing a new one.  Well,
-you might want to check the video4linux mailing list archive first...
-
-Of course you need a correctly installed soundcard unless you have the
-speakers connected directly to the grabber board.  Hint: check the
-mixer settings too.  ALSA for example has everything muted by default.
-
-
-How sound works in detail
-=========================
-
-Still doesn't work?  Looks like some driver hacking is required.
-Below is a do-it-yourself description for you.
-
-The bt8xx chips have 32 general purpose pins, and registers to control
-these pins.  One register is the output enable register
-(BT848_GPIO_OUT_EN), it says which pins are actively driven by the
-bt848 chip.  Another one is the data register (BT848_GPIO_DATA), where
-you can get/set the status if these pins.  They can be used for input
-and output.
-
-Most grabber board vendors use these pins to control an external chip
-which does the sound routing.  But every board is a little different.
-These pins are also used by some companies to drive remote control
-receiver chips.  Some boards use the i2c bus instead of the gpio pins
-to connect the mux chip.
-
-As mentioned above, there is a array which holds the required
-information for each known board.  You basically have to create a new
-line for your board.  The important fields are these two:
-
-struct tvcard
-{
-	[ ... ]
-	u32 gpiomask;
-	u32 audiomux[6]; /* Tuner, Radio, external, internal, mute, stereo */
-};
-
-gpiomask specifies which pins are used to control the audio mux chip.
-The corresponding bits in the output enable register
-(BT848_GPIO_OUT_EN) will be set as these pins must be driven by the
-bt848 chip.
-
-The audiomux[] array holds the data values for the different inputs
-(i.e. which pins must be high/low for tuner/mute/...).  This will be
-written to the data register (BT848_GPIO_DATA) to switch the audio
-mux.
-
-
-What you have to do is figure out the correct values for gpiomask and
-the audiomux array.  If you have Windows and the drivers four your
-card installed, you might to check out if you can read these registers
-values used by the windows driver.  A tool to do this is available
-from ftp://telepresence.dmem.strath.ac.uk/pub/bt848/winutil, but it
-does'nt work with bt878 boards according to some reports I received.
-Another one with bt878 support is available from
-http://btwincap.sourceforge.net/Files/btspy2.00.zip
-
-You might also dig around in the *.ini files of the Windows applications.
-You can have a look at the board to see which of the gpio pins are
-connected at all and then start trial-and-error ...
-
-
-Starting with release 0.7.41 bttv has a number of insmod options to
-make the gpio debugging easier:
-
-bttv_gpio=0/1		enable/disable gpio debug messages
-gpiomask=n		set the gpiomask value
-audiomux=i,j,...	set the values of the audiomux array
-audioall=a		set the values of the audiomux array (one
-			value for all array elements, useful to check
-			out which effect the particular value has).
-
-The messages printed with bttv_gpio=1 look like this:
-
-	bttv0: gpio: en=00000027, out=00000024 in=00ffffd8 [audio: off]
-
-en  =	output _en_able register (BT848_GPIO_OUT_EN)
-out =	_out_put bits of the data register (BT848_GPIO_DATA),
-	i.e. BT848_GPIO_DATA & BT848_GPIO_OUT_EN
-in  = 	_in_put bits of the data register,
-	i.e. BT848_GPIO_DATA & ~BT848_GPIO_OUT_EN
-
-
-
-Other elements of the tvcards array
-===================================
-
-If you are trying to make a new card work you might find it useful to
-know what the other elements in the tvcards array are good for:
-
-video_inputs    - # of video inputs the card has
-audio_inputs    - historical cruft, not used any more.
-tuner           - which input is the tuner
-svhs            - which input is svhs (all others are labeled composite)
-muxsel          - video mux, input->registervalue mapping
-pll             - same as pll= insmod option
-tuner_type      - same as tuner= insmod option
-*_modulename    - hint whenever some card needs this or that audio
-		  module loaded to work properly.
-has_radio	- whenever this TV card has a radio tuner.
-no_msp34xx	- "1" disables loading of msp3400.o module
-no_tda9875	- "1" disables loading of tda9875.o module
-needs_tvaudio	- set to "1" to load tvaudio.o module
-
-If some config item is specified both from the tvcards array and as
-insmod option, the insmod option takes precedence.
-
-
-
-Good luck,
-
-  Gerd
-
-
-PS: If you have a new working entry, mail it to me.

-			Programmer's View of Cpia2
-
-Cpia2 is the second generation video coprocessor from VLSI Vision Ltd (now a
-division of ST Microelectronics).  There are two versions.  The first is the
-STV0672, which is capable of up to 30 frames per second (fps) in frame sizes
-up to CIF, and 15 fps for VGA frames.  The STV0676 is an improved version,
-which can handle up to 30 fps VGA.  Both coprocessors can be attached to two
-CMOS sensors - the vvl6410 CIF sensor and the vvl6500 VGA sensor.  These will
-be referred to as the 410 and the 500 sensors, or the CIF and VGA sensors.
-
-The two chipsets operate almost identically.  The core is an 8051 processor,
-running two different versions of firmware.  The 672 runs the VP4 video
-processor code, the 676 runs VP5.  There are a few differences in register
-mappings for the two chips.  In these cases, the symbols defined in the
-header files are marked with VP4 or VP5 as part of the symbol name.
-
-The cameras appear externally as three sets of registers. Setting register
-values is the only way to control the camera.  Some settings are
-interdependant, such as the sequence required to power up the camera. I will
-try to make note of all of these cases.
-
-The register sets are called blocks.  Block 0 is the system block.  This
-section is always powered on when the camera is plugged in.  It contains
-registers that control housekeeping functions such as powering up the video
-processor.  The video processor is the VP block.  These registers control
-how the video from the sensor is processed.  Examples are timing registers,
-user mode (vga, qvga), scaling, cropping, framerates, and so on.  The last
-block is the video compressor (VC).  The video stream sent from the camera is
-compressed as Motion JPEG (JPEGA).  The VC controls all of the compression
-parameters.  Looking at the file cpia2_registers.h, you can get a full view
-of these registers and the possible values for most of them.
-
-One or more registers can be set or read by sending a usb control message to
-the camera.  There are three modes for this.  Block mode requests a number
-of contiguous registers.  Random mode reads or writes random registers with
-a tuple structure containing address/value pairs.  The repeat mode is only
-used by VP4 to load a firmware patch.  It contains a starting address and
-a sequence of bytes to be written into a gpio port.

-The cx23416 can produce (and the cx23415 can also read) raw YUV output. The
-format of a YUV frame is specific to this chip and is called HM12. 'HM' stands
-for 'Hauppauge Macroblock', which is a misnomer as 'Conexant Macroblock' would
-be more accurate.
-
-The format is YUV 4:2:0 which uses 1 Y byte per pixel and 1 U and V byte per
-four pixels.
-
-The data is encoded as two macroblock planes, the first containing the Y
-values, the second containing UV macroblocks.
-
-The Y plane is divided into blocks of 16x16 pixels from left to right
-and from top to bottom. Each block is transmitted in turn, line-by-line.
-
-So the first 16 bytes are the first line of the top-left block, the
-second 16 bytes are the second line of the top-left block, etc. After
-transmitting this block the first line of the block on the right to the
-first block is transmitted, etc.
-
-The UV plane is divided into blocks of 16x8 UV values going from left
-to right, top to bottom. Each block is transmitted in turn, line-by-line.
-
-So the first 16 bytes are the first line of the top-left block and
-contain 8 UV value pairs (16 bytes in total). The second 16 bytes are the
-second line of 8 UV pairs of the top-left block, etc. After transmitting
-this block the first line of the block on the right to the first block is
-transmitted, etc.
-
-The code below is given as an example on how to convert HM12 to separate
-Y, U and V planes. This code assumes frames of 720x576 (PAL) pixels.
-
-The width of a frame is always 720 pixels, regardless of the actual specified
-width.
-
-If the height is not a multiple of 32 lines, then the captured video is
-missing macroblocks at the end and is unusable. So the height must be a
-multiple of 32.

-Format of embedded V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data
-=========================================================
-
-This document describes the V4L2_MPEG_STREAM_VBI_FMT_IVTV format of the VBI data
-embedded in an MPEG-2 program stream. This format is in part dictated by some
-hardware limitations of the ivtv driver (the driver for the Conexant cx23415/6
-chips), in particular a maximum size for the VBI data. Anything longer is cut
-off when the MPEG stream is played back through the cx23415.
-
-The advantage of this format is it is very compact and that all VBI data for
-all lines can be stored while still fitting within the maximum allowed size.
-
-The stream ID of the VBI data is 0xBD. The maximum size of the embedded data is
-4 + 43 * 36, which is 4 bytes for a header and 2 * 18 VBI lines with a 1 byte
-header and a 42 bytes payload each. Anything beyond this limit is cut off by
-the cx23415/6 firmware. Besides the data for the VBI lines we also need 36 bits
-for a bitmask determining which lines are captured and 4 bytes for a magic cookie,
-signifying that this data package contains V4L2_MPEG_STREAM_VBI_FMT_IVTV VBI data.
-If all lines are used, then there is no longer room for the bitmask. To solve this
-two different magic numbers were introduced:
-
-'itv0': After this magic number two unsigned longs follow. Bits 0-17 of the first
-unsigned long denote which lines of the first field are captured. Bits 18-31 of
-the first unsigned long and bits 0-3 of the second unsigned long are used for the
-second field.
-
-'ITV0': This magic number assumes all VBI lines are captured, i.e. it implicitly
-implies that the bitmasks are 0xffffffff and 0xf.
-
-After these magic cookies (and the 8 byte bitmask in case of cookie 'itv0') the
-captured VBI lines start:
-
-For each line the least significant 4 bits of the first byte contain the data type.
-Possible values are shown in the table below. The payload is in the following 42
-bytes.
-
-Here is the list of possible data types:
-
-#define IVTV_SLICED_TYPE_TELETEXT       0x1     // Teletext (uses lines 6-22 for PAL)
-#define IVTV_SLICED_TYPE_CC             0x4     // Closed Captions (line 21 NTSC)
-#define IVTV_SLICED_TYPE_WSS            0x5     // Wide Screen Signal (line 23 PAL)
-#define IVTV_SLICED_TYPE_VPS            0x7     // Video Programming System (PAL) (line 16)

-This page describes how to make calls to the firmware api.
-
-How to call
-===========
-
-The preferred calling convention is known as the firmware mailbox. The
-mailboxes are basically a fixed length array that serves as the call-stack.
-
-Firmware mailboxes can be located by searching the encoder and decoder memory
-for a 16 byte signature. That signature will be located on a 256-byte boundary.
-
-Signature:
-0x78, 0x56, 0x34, 0x12, 0x12, 0x78, 0x56, 0x34,
-0x34, 0x12, 0x78, 0x56, 0x56, 0x34, 0x12, 0x78
-
-The firmware implements 20 mailboxes of 20 32-bit words. The first 10 are
-reserved for API calls. The second 10 are used by the firmware for event
-notification.
-
-  Index  Name
-  -----  ----
-  0      Flags
-  1      Command
-  2      Return value
-  3      Timeout
-  4-19   Parameter/Result
-
-
-The flags are defined in the following table. The direction is from the
-perspective of the firmware.
-
-  Bit  Direction  Purpose
-  ---  ---------  -------
-  2    O          Firmware has processed the command.
-  1    I          Driver has finished setting the parameters.
-  0    I          Driver is using this mailbox.
-
-
-The command is a 32-bit enumerator. The API specifics may be found in the
-fw-*-api.txt documents.
-
-The return value is a 32-bit enumerator. Only two values are currently defined:
-0=success and -1=command undefined.
-
-There are 16 parameters/results 32-bit fields. The driver populates these fields
-with values for all the parameters required by the call. The driver overwrites
-these fields with result values returned by the call. The API specifics may be
-found in the fw-*-api.txt documents.
-
-The timeout value protects the card from a hung driver thread. If the driver
-doesn't handle the completed call within the timeout specified, the firmware
-will reset that mailbox.
-
-To make an API call, the driver iterates over each mailbox looking for the
-first one available (bit 0 has been cleared). The driver sets that bit, fills
-in the command enumerator, the timeout value and any required parameters. The
-driver then sets the parameter ready bit (bit 1). The firmware scans the
-mailboxes for pending commands, processes them, sets the result code, populates
-the result value array with that call's return values and sets the call
-complete bit (bit 2). Once bit 2 is set, the driver should retrieve the results
-and clear all the flags. If the driver does not perform this task within the
-time set in the timeout register, the firmware will reset that mailbox.
-
-Event notifications are sent from the firmware to the host. The host tells the
-firmware which events it is interested in via an API call. That call tells the
-firmware which notification mailbox to use. The firmware signals the host via
-an interrupt. Only the 16 Results fields are used, the Flags, Command, Return
-value and Timeout words are not used.

-Decoder firmware API description
-================================
-
-Note: this API is part of the decoder firmware, so it's cx23415 only.
-
--------------------------------------------------------------------------------
-
-Name 	CX2341X_DEC_PING_FW
-Enum 	0/0x00
-Description
-	This API call does nothing. It may be used to check if the firmware
-	is responding.
-
--------------------------------------------------------------------------------
-
-Name 	CX2341X_DEC_START_PLAYBACK
-Enum 	1/0x01
-Description
-	Begin or resume playback.
-Param[0]
-	0 based frame number in GOP to begin playback from.
-Param[1]
-	Specifies the number of muted audio frames to play before normal
-	audio resumes. (This is not implemented in the firmware, leave at 0)
-
--------------------------------------------------------------------------------
-
-Name 	CX2341X_DEC_STOP_PLAYBACK
-Enum 	2/0x02
-Description
-	Ends playback and clears all decoder buffers. If PTS is not zero,
-	playback stops at specified PTS.
-Param[0]
-	Display 0=last frame, 1=black
-	Note: this takes effect immediately, so if you want to wait for a PTS,
-	then use '0', otherwise the screen goes to black at once.
-	You can call this later (even if there is no playback) with a 1 value
-	to set the screen to black.
-Param[1]
-	PTS low
-Param[2]
-	PTS high
-
--------------------------------------------------------------------------------
-
-Name 	CX2341X_DEC_SET_PLAYBACK_SPEED
-Enum 	3/0x03
-Description
-	Playback stream at speed other than normal. There are two modes of
-	operation:
-	    Smooth: host transfers entire stream and firmware drops unused
-		    frames.
-	    Coarse: host drops frames based on indexing as required to achieve
-		    desired speed.
-Param[0]
-	Bitmap:
-	    0:7  0 normal
-		 1 fast only "1.5 times"
-		 n nX fast, 1/nX slow
-	    30   Framedrop:
-		     '0' during 1.5 times play, every other B frame is dropped
-		     '1' during 1.5 times play, stream is unchanged (bitrate
-			 must not exceed 8mbps)
-	    31   Speed:
-		     '0' slow
-		     '1' fast
-	Note: n is limited to 2. Anything higher does not result in
-	faster playback. Instead the host should start dropping frames.
-Param[1]
-	Direction: 0=forward, 1=reverse
-	Note: to make reverse playback work you have to write full GOPs in
-	reverse order.
-Param[2]
-	Picture mask:
-	    1=I frames
-	    3=I, P frames
-	    7=I, P, B frames
-Param[3]
-	B frames per GOP (for reverse play only)
-	Note: for reverse playback the Picture Mask should be set to I or I, P.
-	Adding B frames to the mask will result in corrupt video. This field
-	has to be set to the correct value in order to keep the timing correct.
-Param[4]
-	Mute audio: 0=disable, 1=enable
-Param[5]
-	Display 0=frame, 1=field
-Param[6]
-	Specifies the number of muted audio frames to play before normal audio

-PVR350 Video decoder registers 0x02002800 -> 0x02002B00
-=======================================================
-
-This list has been worked out through trial and error. There will be mistakes
-and omissions. Some registers have no obvious effect so it's hard to say what
-they do, while others interact with each other, or require a certain load
-sequence. Horizontal filter setup is one example, with six registers working
-in unison and requiring a certain load sequence to correctly configure. The
-indexed colour palette is much easier to set at just two registers, but again
-it requires a certain load sequence.
-
-Some registers are fussy about what they are set to. Load in a bad value & the
-decoder will fail. A firmware reload will often recover, but sometimes a reset
-is required. For registers containing size information, setting them to 0 is
-generally a bad idea. For other control registers i.e. 2878, you'll only find
-out what values are bad when it hangs.

----------------
-2818
-      bits 0:31
-	Decoder horizontal Y alias trigger
-
-     These six registers control the horizontal aliasing filter for the Y plane.
-     The first five registers must all be loaded before accessing the trigger
-     (2818), as this register actually clocks the data through for the first
-     five.
-
-     To correctly program set the filter, this whole procedure must be done 16
-     times. The actual register contents are copied from a lookup-table in the
-     firmware which contains 4 different filter settings.

-	Decoder horizontal UV alias trigger
-
-     These six registers control the horizontal aliasing for the UV plane.
-     Operation is the same as the Y filter, with 2830 being the trigger
-     register.

-      bits 0:15
-	Decoder UV source width in pixels
-
-      bits 16:31
-	Decoder UV destination width in pixels
-
-     NOTE: For both registers, the resulting image must be fully visible on
-     screen. If the image exceeds the right edge both the source and destination
-     size must be adjusted to reflect the visible portion. For the source width,
-     you must take into account the scaling when calculating the new value.

-
-     Most of these registers either control horizontal scaling, or appear linked
-     to it in some way. Register 2854 contains the 'master' value & the other
-     registers can be calculated from that one. You must also remember to
-     correctly set the divider in Reg 2874.
-
-     To enlarge:
-	     Reg 2854 = (source_width * 0x00200000) / destination_width
-	     Reg 2874 = No divide
-
-     To reduce from full size down to half size:
-	     Reg 2854 = (source_width/2 * 0x00200000) / destination width
-	     Reg 2874 = Divide by 2
-
-     To reduce from half size down to quarter size:
-	     Reg 2854 = (source_width/4 * 0x00200000) / destination width
-	     Reg 2874 = Divide by 4
-
-     The result is always rounded up.

---------------------------------------------------------------------------------
-288C
-      bits 0:15
-	osd ?? unknown
-	  Appears to affect the osd position stability. The higher the value the
-	  more unstable it becomes. Decoder output remains stable.
-
-      bits 16:31
-	osd ?? unknown
-	  Same as bits 0:15
-
---------------------------------------------------------------------------------
-2890
-      bits 0:11
-	Decoder output horizontal offset.
-
-     Horizontal offset moves the video image right. A small left shift is
-     possible, but it's better to use reg 2870 for that due to its greater
-     range.
-
-     NOTE: Video corruption will occur if video window is shifted off the right
-     edge. To avoid this read the notes for 2834 & 2838.
---------------------------------------------------------------------------------
-2894
-      bits 0:23
-	Decoder output video surround colour.
-
-     Contains the colour (in yuv) used to fill the screen when the video is
-     running in a window.
---------------------------------------------------------------------------------
-2898
-      bits 0:23
-	Decoder video window colour
-	  Contains the colour (in yuv) used to fill the video window when the
-	  video is turned off.
-
-      bit 24
-	Decoder video output
-	  0 = Video on
-	  1 = Video off
-
-      bit 28
-	Decoder plane order
-	  0 = Y,UV
-	  1 = UV,Y
-
-      bit 29
-	Decoder second plane byte order
-	  0 = Normal (UV)
-	  1 = Swapped (VU)
-
-     In normal usage, the first plane is Y & the second plane is UV. Though the
-     order of the planes can be swapped, only the byte order of the second plane
-     can be swapped. This isn't much use for the Y plane, but can be useful for
-     the UV plane.

-289C
-      bits 0:15
-	Decoder vertical field offset 1
-
-      bits 16:31
-	Decoder vertical field offset 2
-
-     Controls field output vertical alignment. The higher the number, the lower
-     the image on screen. Known starting values are 0x011E0017 (NTSC) &

-28A0
-      bits 0:15
-	Decoder & osd width in pixels

-	Decoder & osd height in pixels
-
-     All output from the decoder & osd are disabled beyond this area. Decoder
-     output will simply go black outside of this region. If the osd tries to
-     exceed this area it will become corrupt.
---------------------------------------------------------------------------------
-28A4
-      bits 0:11

-      bits 0:31
-	Decoder vertical Y alias register 2
----------------
-2908
-      bits 0:31
-	Decoder vertical Y alias trigger
-
-     These three registers control the vertical aliasing filter for the Y plane.
-     Operation is similar to the horizontal Y filter (2804). The only real
-     difference is that there are only two registers to set before accessing
-     the trigger register (2908). As for the horizontal filter, the values are
-     taken from a lookup table in the firmware, and the procedure must be
-     repeated 16 times to fully program the filter.

-      bits 0:15
-	Decoder UV source height in pixels divided by 2
-
-      bits 16:31
-	Decoder UV destination height in pixels
-
-     NOTE: For both registers, the resulting image must be fully visible on
-     screen. If the image exceeds the bottom edge both the source and
-     destination size must be adjusted to reflect the visible portion. For the
-     source height, you must take into account the scaling when calculating the

-
-     When the bits-per-pixel is set to 8, the colour mode is ignored and
-     assumed to be 8 bit indexed. For 16 & 32 bits-per-pixel the colour depth
-     is honoured, and when using a colour depth that requires fewer bytes than
-     allocated the extra bytes are used as padding. So for a 32 bpp with 8 bit
-     index colour, there are 3 padding bytes per pixel. It's also possible to
-     select 16bpp with a 32 bit colour mode. This results in the pixel width
-     being doubled, but the color key will not work as expected in this mode.
-
-     Colour key is as it suggests. You designate a colour which will become
-     completely transparent. When using 565, 555 or 444 colour modes, the
-     colour key is always 16 bits wide. The colour to key on is set in Reg 2A18.
-
-     Local alpha works differently depending on the colour mode. For 32bpp & 8
-     bit indexed, local alpha is a per-pixel 256 step transparency, with 0 being
-     transparent and 255 being solid. For the 16bpp modes 555 & 444, the unused
-     bit(s) act as a simple transparency switch, with 0 being solid & 1 being
-     fully transparent. There is no local alpha support for 16bit 565.
-
-     Global alpha is a 256 step transparency that applies to the entire osd,
-     with 0 being transparent & 255 being solid.
-
-     It's possible to combine colour key, local alpha & global alpha.

-This page describes the structures and procedures used by the cx2341x DMA
-engine.
-
-Introduction
-============
-
-The cx2341x PCI interface is busmaster capable. This means it has a DMA
-engine to efficiently transfer large volumes of data between the card and main
-memory without requiring help from a CPU. Like most hardware, it must operate
-on contiguous physical memory. This is difficult to come by in large quantities
-on virtual memory machines.
-
-Therefore, it also supports a technique called "scatter-gather". The card can
-transfer multiple buffers in one operation. Instead of allocating one large
-contiguous buffer, the driver can allocate several smaller buffers.
-
-In practice, I've seen the average transfer to be roughly 80K, but transfers
-above 128K were not uncommon, particularly at startup. The 128K figure is
-important, because that is the largest block that the kernel can normally
-allocate. Even still, 128K blocks are hard to come by, so the driver writer is
-urged to choose a smaller block size and learn the scatter-gather technique.
-
-Mailbox #10 is reserved for DMA transfer information.
-
-Note: the hardware expects little-endian data ('intel format').
-
-Flow
-====
-
-This section describes, in general, the order of events when handling DMA
-transfers. Detailed information follows this section.
-
-- The card raises the Encoder interrupt.
-- The driver reads the transfer type, offset and size from Mailbox #10.
-- The driver constructs the scatter-gather array from enough free dma buffers
-  to cover the size.
-- The driver schedules the DMA transfer via the ScheduleDMAtoHost API call.
-- The card raises the DMA Complete interrupt.
-- The driver checks the DMA status register for any errors.
-- The driver post-processes the newly transferred buffers.
-
-NOTE! It is possible that the Encoder and DMA Complete interrupts get raised
-simultaneously. (End of the last, start of the next, etc.)
-
-Mailbox #10
-===========
-
-The Flags, Command, Return Value and Timeout fields are ignored.
-
-Name:       Mailbox #10
-Results[0]: Type: 0: MPEG.
-Results[1]: Offset: The position relative to the card's memory space.
-Results[2]: Size: The exact number of bytes to transfer.
-
-My speculation is that since the StartCapture API has a capture type of "RAW"
-available, that the type field will have other values that correspond to YUV
-and PCM data.
-
-Scatter-Gather Array
-====================
-
-The scatter-gather array is a contiguously allocated block of memory that
-tells the card the source and destination of each data-block to transfer.
-Card "addresses" are derived from the offset supplied by Mailbox #10. Host
-addresses are the physical memory location of the target DMA buffer.
-
-Each S-G array element is a struct of three 32-bit words. The first word is
-the source address, the second is the destination address. Both take up the
-entire 32 bits. The lowest 18 bits of the third word is the transfer byte
-count. The high-bit of the third word is the "last" flag. The last-flag tells
-the card to raise the DMA_DONE interrupt. From hard personal experience, if
-you forget to set this bit, the card will still "work" but the stream will
-most likely get corrupted.
-
-The transfer count must be a multiple of 256. Therefore, the driver will need
-to track how much data in the target buffer is valid and deal with it
-accordingly.
-
-Array Element:
-
-- 32-bit Source Address
-- 32-bit Destination Address
-- 14-bit reserved (high bit is the last flag)
-- 18-bit byte count
-
-DMA Transfer Status
-===================
-
-Register 0x0004 holds the DMA Transfer Status:
-
-Bit
-0   read completed
-1   write completed
-2   DMA read error
-3   DMA write error
-4   Scatter-Gather array error

-This document describes the cx2341x memory map and documents some of the register
-space.
-
-Note: the memory long words are little-endian ('intel format').
-
-Warning! This information was figured out from searching through the memory and
-registers, this information may not be correct and is certainly not complete, and
-was not derived from anything more than searching through the memory space with
-commands like:
-
-	ivtvctl -O min=0x02000000,max=0x020000ff
-
-So take this as is, I'm always searching for more stuff, it's a large
-register space :-).
-
-Memory Map
-==========
-
-The cx2341x exposes its entire 64M memory space to the PCI host via the PCI BAR0
-(Base Address Register 0). The addresses here are offsets relative to the
-address held in BAR0.
-
-0x00000000-0x00ffffff Encoder memory space
-0x00000000-0x0003ffff Encode.rom
-      ???-???         MPEG buffer(s)
-      ???-???         Raw video capture buffer(s)
-      ???-???         Raw audio capture buffer(s)
-      ???-???         Display buffers (6 or 9)
-
-0x01000000-0x01ffffff Decoder memory space
-0x01000000-0x0103ffff Decode.rom
-      ???-???         MPEG buffers(s)
-0x0114b000-0x0115afff Audio.rom (deprecated?)
-
-0x02000000-0x0200ffff Register Space
-
-Registers
-=========
-
-The registers occupy the 64k space starting at the 0x02000000 offset from BAR0.
-All of these registers are 32 bits wide.
-
-DMA Registers 0x000-0xff:
-
- 0x00 - Control:
-	0=reset/cancel, 1=read, 2=write, 4=stop
- 0x04 - DMA status:
-	1=read busy, 2=write busy, 4=read error, 8=write error, 16=link list error
- 0x08 - pci DMA pointer for read link list
- 0x0c - pci DMA pointer for write link list
- 0x10 - read/write DMA enable:
-	1=read enable, 2=write enable
- 0x14 - always 0xffffffff, if set any lower instability occurs, 0x00 crashes
- 0x18 - ??
- 0x1c - always 0x20 or 32, smaller values slow down DMA transactions
- 0x20 - always value of 0x780a010a
- 0x24-0x3c - usually just random values???
- 0x40 - Interrupt status
- 0x44 - Write a bit here and shows up in Interrupt status 0x40
- 0x48 - Interrupt Mask
- 0x4C - always value of 0xfffdffff,
-	if changed to 0xffffffff DMA write interrupts break.
- 0x50 - always 0xffffffff
- 0x54 - always 0xffffffff (0x4c, 0x50, 0x54 seem like interrupt masks, are
-	3 processors on chip, Java ones, VPU, SPU, APU, maybe these are the
-	interrupt masks???).
- 0x60-0x7C - random values
- 0x80 - first write linked list reg, for Encoder Memory addr
- 0x84 - first write linked list reg, for pci memory addr
- 0x88 - first write linked list reg, for length of buffer in memory addr
-	(|0x80000000 or this for last link)
- 0x8c-0xdc - rest of write linked list reg, 8 sets of 3 total, DMA goes here
-	from linked list addr in reg 0x0c, firmware must push through or
-	something.
- 0xe0 - first (and only) read linked list reg, for pci memory addr
- 0xe4 - first (and only) read linked list reg, for Decoder memory addr
- 0xe8 - first (and only) read linked list reg, for length of buffer
- 0xec-0xff - Nothing seems to be in these registers, 0xec-f4 are 0x00000000.
-
-Memory locations for Encoder Buffers 0x700-0x7ff:
-
-These registers show offsets of memory locations pertaining to each
-buffer area used for encoding, have to shift them by <<1 first.
-
-0x07F8: Encoder SDRAM refresh
-0x07FC: Encoder SDRAM pre-charge
-
-Memory locations for Decoder Buffers 0x800-0x8ff:

-This document describes how to upload the cx2341x firmware to the card.
-
-How to find
-===========
-
-See the web pages of the various projects that uses this chip for information
-on how to obtain the firmware.
-
-The firmware stored in a Windows driver can be detected as follows:
-
-- Each firmware image is 256k bytes.
-- The 1st 32-bit word of the Encoder image is 0x0000da7
-- The 1st 32-bit word of the Decoder image is 0x00003a7
-- The 2nd 32-bit word of both images is 0xaa55bb66
-
-How to load
-===========
-
-- Issue the FWapi command to stop the encoder if it is running. Wait for the
-  command to complete.
-- Issue the FWapi command to stop the decoder if it is running. Wait for the
-  command to complete.
-- Issue the I2C command to the digitizer to stop emitting VSYNC events.
-- Issue the FWapi command to halt the encoder's firmware.
-- Sleep for 10ms.
-- Issue the FWapi command to halt the decoder's firmware.
-- Sleep for 10ms.
-- Write 0x00000000 to register 0x2800 to stop the Video Display Module.
-- Write 0x00000005 to register 0x2D00 to stop the AO (audio output?).
-- Write 0x00000000 to register 0xA064 to ping? the APU.
-- Write 0xFFFFFFFE to register 0x9058 to stop the VPU.
-- Write 0xFFFFFFFF to register 0x9054 to reset the HW blocks.
-- Write 0x00000001 to register 0x9050 to stop the SPU.
-- Sleep for 10ms.
-- Write 0x0000001A to register 0x07FC to init the Encoder SDRAM's pre-charge.

-- Write 0x80000640 to register 0x08F8 to init the Decoder SDRAM's refresh to 1us.
-- Sleep for 512ms. (600ms is recommended)
-- Transfer the encoder's firmware image to offset 0 in Encoder memory space.
-- Transfer the decoder's firmware image to offset 0 in Decoder memory space.
-- Use a read-modify-write operation to Clear bit 0 of register 0x9050 to
-  re-enable the SPU.
-- Sleep for 1 second.
-- Use a read-modify-write operation to Clear bits 3 and 0 of register 0x9058

-Constraints
------------
-  a) Image size for YUV422P format
-     All YUV422P images are enforced to have width x height % 16 = 0.
-     This is due to DMA constraints, which transfers only planes of 8 byte
-     multiples.
-
-
-Global video workflow
----------------------
-  a) QCI stopped
-     Initialy, the QCI interface is stopped.
-     When a buffer is queued (pxa_videobuf_ops->buf_queue), the QCI starts.
-
-  b) QCI started
-     More buffers can be queued while the QCI is started without halting the
-     capture.  The new buffers are "appended" at the tail of the DMA chain, and
-     smoothly captured one frame after the other.
-
-     Once a buffer is filled in the QCI interface, it is marked as "DONE" and
-     removed from the active buffers list. It can be then requeud or dequeued by
-     userland application.
-
-     Once the last buffer is filled in, the QCI interface stops.
-
-  c) Capture global finite state machine schema

-
-DMA usage
----------
-  a) DMA flow
-     - first buffer queued for capture
-       Once a first buffer is queued for capture, the QCI is started, but data
-       transfer is not started. On "End Of Frame" interrupt, the irq handler
-       starts the DMA chain.
-     - capture of one videobuffer
-       The DMA chain starts transferring data into videobuffer RAM pages.
-       When all pages are transferred, the DMA irq is raised on "ENDINTR" status
-     - finishing one videobuffer
-       The DMA irq handler marks the videobuffer as "done", and removes it from
-       the active running queue
-       Meanwhile, the next videobuffer (if there is one), is transferred by DMA
-     - finishing the last videobuffer
-       On the DMA irq of the last videobuffer, the QCI is stopped.
-
-  b) DMA prepared buffer will have this structure
-
-     +------------+-----+---------------+-----------------+
-     | desc-sg[0] | ... | desc-sg[last] | finisher/linker |
-     +------------+-----+---------------+-----------------+
-
-     This structure is pointed by dma->sg_cpu.
-     The descriptors are used as follows :
-      - desc-sg[i]: i-th descriptor, transferring the i-th sg
-        element to the video buffer scatter gather
-      - finisher: has ddadr=DADDR_STOP, dcmd=ENDIRQEN
-      - linker: has ddadr= desc-sg[0] of next video buffer, dcmd=0
-
-     For the next schema, let's assume d0=desc-sg[0] .. dN=desc-sg[N],
-     "f" stands for finisher and "l" for linker.
-     A typical running chain is :
-
-         Videobuffer 1         Videobuffer 2
-     +---------+----+---+  +----+----+----+---+
-     | d0 | .. | dN | l |  | d0 | .. | dN | f |
-     +---------+----+-|-+  ^----+----+----+---+
-                      |    |
-                      +----+
-
-     After the chaining is finished, the chain looks like :
-
-         Videobuffer 1         Videobuffer 2         Videobuffer 3
-     +---------+----+---+  +----+----+----+---+  +----+----+----+---+
-     | d0 | .. | dN | l |  | d0 | .. | dN | l |  | d0 | .. | dN | f |
-     +---------+----+-|-+  ^----+----+----+-|-+  ^----+----+----+---+
-                      |    |                |    |
-                      +----+                +----+
-                                           new_link
-
-  c) DMA hot chaining timeslice issue
-
-     As DMA chaining is done while DMA _is_ running, the linking may be done
-     while the DMA jumps from one Videobuffer to another. On the schema, that
-     would be a problem if the following sequence is encountered :
-
-      - DMA chain is Videobuffer1 + Videobuffer2
-      - pxa_videobuf_queue() is called to queue Videobuffer3
-      - DMA controller finishes Videobuffer2, and DMA stops
-      =>
-         Videobuffer 1         Videobuffer 2
-     +---------+----+---+  +----+----+----+---+
-     | d0 | .. | dN | l |  | d0 | .. | dN | f |
-     +---------+----+-|-+  ^----+----+----+-^-+
-                      |    |                |
-                      +----+                +-- DMA DDADR loads DDADR_STOP
-
-      - pxa_dma_add_tail_buf() is called, the Videobuffer2 "finisher" is
-        replaced by a "linker" to Videobuffer3 (creation of new_link)
-      - pxa_videobuf_queue() finishes
-      - the DMA irq handler is called, which terminates Videobuffer2
-      - Videobuffer3 capture is not scheduled on DMA chain (as it stopped !!!)
-
-         Videobuffer 1         Videobuffer 2         Videobuffer 3
-     +---------+----+---+  +----+----+----+---+  +----+----+----+---+
-     | d0 | .. | dN | l |  | d0 | .. | dN | l |  | d0 | .. | dN | f |
-     +---------+----+-|-+  ^----+----+----+-|-+  ^----+----+----+---+
-                      |    |                |    |
-                      +----+                +----+
-                                           new_link
-                                          DMA DDADR still is DDADR_STOP
-
-      - pxa_camera_check_link_miss() is called
-        This checks if the DMA is finished and a buffer is still on the
-        pcdev->capture list. If that's the case, the capture will be restarted,
-        and Videobuffer3 is scheduled on DMA chain.
-      - the DMA irq handler finishes
-
-     Note: if DMA stops just after pxa_camera_check_link_miss() reads DDADR()
-     value, we have the guarantee that the DMA irq handler will be called back
-     when the DMA will finish the buffer, and pxa_camera_check_link_miss() will
-     be called again, to reschedule Videobuffer3.

-NOTES ON RADIOTRACK CARD CONTROL
-by Stephen M. Benoit (benoits@servicepro.com)  Dec 14, 1996
-----------------------------------------------------------------------------
-
-Document version 1.0
-
-ACKNOWLEDGMENTS
-----------------
-This document was made based on 'C' code for Linux from Gideon le Grange
-(legrang@active.co.za or legrang@cs.sun.ac.za) in 1994, and elaborations from
-Frans Brinkman (brinkman@esd.nl) in 1996.  The results reported here are from
-experiments that the author performed on his own setup, so your mileage may
-vary... I make no guarantees, claims or warranties to the suitability or
-validity of this information.  No other documentation on the AIMS
-Lab (http://www.aimslab.com/) RadioTrack card was made available to the
-author.  This document is offered in the hopes that it might help users who
-want to use the RadioTrack card in an environment other than MS Windows.
-
-WHY THIS DOCUMENT?
-------------------
-I have a RadioTrack card from back when I ran an MS-Windows platform.  After
-converting to Linux, I found Gideon le Grange's command-line software for
-running the card, and found that it was good!  Frans Brinkman made a
-comfortable X-windows interface, and added a scanning feature.  For hack
-value, I wanted to see if the tuner could be tuned beyond the usual FM radio
-broadcast band, so I could pick up the audio carriers from North American
-broadcast TV channels, situated just below and above the 87.0-109.0 MHz range.
-I did not get much success, but I learned about programming ioports under
-Linux and gained some insights about the hardware design used for the card.
-
-So, without further delay, here are the details.
-
-
-PHYSICAL DESCRIPTION
---------------------
-The RadioTrack card is an ISA 8-bit FM radio card.  The radio frequency (RF)
-input is simply an antenna lead, and the output is a power audio signal
-available through a miniature phone plug.  Its RF frequencies of operation are
-more or less limited from 87.0 to 109.0 MHz (the commercial FM broadcast
-band).  Although the registers can be programmed to request frequencies beyond
-these limits, experiments did not give promising results.  The variable
-frequency oscillator (VFO) that demodulates the intermediate frequency (IF)
-signal probably has a small range of useful frequencies, and wraps around or
-gets clipped beyond the limits mentioned above.
-
-
-CONTROLLING THE CARD WITH IOPORT
---------------------------------
-The RadioTrack (base) ioport is configurable for 0x30c or 0x20c.  Only one
-ioport seems to be involved.  The ioport decoding circuitry must be pretty
-simple, as individual ioport bits are directly matched to specific functions
-(or blocks) of the radio card.  This way, many functions can be changed in
-parallel with one write to the ioport.  The only feedback available through
-the ioports appears to be the "Stereo Detect" bit.
-
-The bits of the ioport are arranged as follows:
-
-  MSb                                                         LSb
-+------+------+------+--------+--------+-------+---------+--------+
-| VolA | VolB | ???? | Stereo | Radio  | TuneA | TuneB   | Tune   |
-|  (+) |  (-) |      | Detect | Audio  | (bit) | (latch) | Update |
-|      |      |      | Enable | Enable |       |         | Enable |
-+------+------+------+--------+--------+-------+---------+--------+
-
-
-VolA . VolB  [AB......]
------------
-0 0 : audio mute
-0 1 : volume +    (some delay required)
-1 0 : volume -    (some delay required)
-1 1 : stay at present volume
-
-Stereo Detect Enable [...S....]
---------------------
-0 : No Detect
-1 : Detect
-
-  Results available by reading ioport >60 msec after last port write.
-  0xff ==> no stereo detected,  0xfd ==> stereo detected.
-
-Radio to Audio (path) Enable [....R...]
-----------------------------
-0 : Disable path (silence)
-1 : Enable path  (audio produced)
-
-TuneA . TuneB [.....AB.]
--------------
-0 0 : "zero" bit phase 1
-0 1 : "zero" bit phase 2
-
-1 0 : "one" bit phase 1
-1 1 : "one" bit phase 2
-
-  24-bit code, where bits = (freq*40) + 10486188.
-  The Most Significant 11 bits must be 1010 xxxx 0x0 to be valid.
-  The bits are shifted in LSb first.
-
-Tune Update Enable [.......T]
-------------------
-0 : Tuner held constant
-1 : Tuner updating in progress
-
-

-Driver for I2C radios for the Silicon Labs Si4713 FM Radio Transmitters
-
-Copyright (c) 2009 Nokia Corporation
-Contact: Eduardo Valentin <eduardo.valentin@nokia.com>
-
-
-Information about the Device
-============================
-This chip is a Silicon Labs product. It is a I2C device, currently on 0x63 address.
-Basically, it has transmission and signal noise level measurement features.
-
-The Si4713 integrates transmit functions for FM broadcast stereo transmission.
-The chip also allows integrated receive power scanning to identify low signal
-power FM channels.
-
-The chip is programmed using commands and responses. There are also several
-properties which can change the behavior of this chip.
-
-Users must comply with local regulations on radio frequency (RF) transmission.
-
-Device driver description
-=========================
-There are two modules to handle this device. One is a I2C device driver
-and the other is a platform driver.
-
-The I2C device driver exports a v4l2-subdev interface to the kernel.
-All properties can also be accessed by v4l2 extended controls interface, by
-using the v4l2-subdev calls (g_ext_ctrls, s_ext_ctrls).
-
-The platform device driver exports a v4l2 radio device interface to user land.
-So, it uses the I2C device driver as a sub device in order to send the user
-commands to the actual device. Basically it is a wrapper to the I2C device driver.
-
-Applications can use v4l2 radio API to specify frequency of operation, mute state,
-etc. But mostly of its properties will be present in the extended controls.
-
-When the v4l2 mute property is set to 1 (true), the driver will turn the chip off.
-
-Properties description
-======================
-
-The properties can be accessed using v4l2 extended controls.
-Here is an output from v4l2-ctl util:
-/ # v4l2-ctl -d /dev/radio0 --all -L

-/ #
-
-Here is a summary of them:
-
-* Pilot is an audible tone sent by the device.
-
-pilot_frequency - Configures the frequency of the stereo pilot tone.
-pilot_deviation - Configures pilot tone frequency deviation level.
-pilot_enabled - Enables or disables the pilot tone feature.
-
-* The si4713 device is capable of applying audio compression to the transmitted signal.
-
-acomp_enabled - Enables or disables the audio dynamic range control feature.
-acomp_gain - Sets the gain for audio dynamic range control.
-acomp_threshold - Sets the threshold level for audio dynamic range control.
-acomp_attack_time - Sets the attack time for audio dynamic range control.
-acomp_release_time - Sets the release time for audio dynamic range control.
-
-* Limiter setups audio deviation limiter feature. Once a over deviation occurs,
-it is possible to adjust the front-end gain of the audio input and always
-prevent over deviation.
-
-limiter_enabled - Enables or disables the limiter feature.
-limiter_deviation - Configures audio frequency deviation level.
-limiter_release_time - Sets the limiter release time.
-
-* Tuning power
-
-power_level - Sets the output power level for signal transmission.
-antenna_capacitor - This selects the value of antenna tuning capacitor manually
-or automatically if set to zero.
-
-* RDS related
-
-rds_ps_name - Sets the RDS ps name field for transmission.
-rds_radio_text - Sets the RDS radio text for transmission.
-rds_pi - Sets the RDS PI field for transmission.
-rds_pty - Sets the RDS PTY field for transmission.
-
-* Region related
-
-preemphasis - sets the preemphasis to be applied for transmission.
-
-RNL
-===
-
-This device also has an interface to measure received noise level. To do that, you should
-ioctl the device node. Here is an code of example:
-
-int main (int argc, char *argv[])
-{
-	struct si4713_rnl rnl;
-	int fd = open("/dev/radio0", O_RDWR);
-	int rval;
-
-	if (argc < 2)
-		return -EINVAL;
-
-	if (fd < 0)
-		return fd;
-
-	sscanf(argv[1], "%d", &rnl.frequency);
-
-	rval = ioctl(fd, SI4713_IOC_MEASURE_RNL, &rnl);
-	if (rval < 0)
-		return rval;
-
-	printf("received noise level: %d\n", rnl.rnl);
-
-	close(fd);
-}
-
-The struct si4713_rnl and SI4713_IOC_MEASURE_RNL are defined under
-include/linux/platform_data/media/si4713.h.
-
-Stereo/Mono and RDS subchannels
-===============================
-
-The device can also be configured using the available sub channels for
-transmission. To do that use S/G_MODULATOR ioctl and configure txsubchans properly.
-Refer to the V4L2 API specification for proper use of this ioctl.
-
-Testing
-=======
-Testing is usually done with v4l2-ctl utility for managing FM tuner cards.
-The tool can be found in v4l-dvb repository under v4l2-apps/util directory.
-
-Example for setting rds ps name:
-# v4l2-ctl -d /dev/radio0 --set-ctrl=rds_ps_name="Dummy"

-SI476x Driver Readme
-------------------------------------------------
-	Copyright (C) 2013 Andrey Smirnov <andrew.smirnov@gmail.com>
-
-TODO for the driver
-------------------------------
-
-- According to the SiLabs' datasheet it is possible to update the
-  firmware of the radio chip in the run-time, thus bringing it to the
-  most recent version. Unfortunately I couldn't find any mentioning of
-  the said firmware update for the old chips that I tested the driver
-  against, so for chips like that the driver only exposes the old
-  functionality.
-
-
-Parameters exposed over debugfs
--------------------------------
-SI476x allow user to get multiple characteristics that can be very
-useful for EoL testing/RF performance estimation, parameters that have
-very little to do with V4L2 subsystem. Such parameters are exposed via
-debugfs and can be accessed via regular file I/O operations.
-
-The drivers exposes following files:
-
-* /sys/kernel/debug/<device-name>/acf
-  This file contains ACF(Automatically Controlled Features) status
-  information. The contents of the file is binary data of the
-  following layout:

-/**
- * DOC: Digital TV Demux
- *
- * The Kernel Digital TV Demux kABI defines a driver-internal interface for
- * registering low-level, hardware specific driver to a hardware independent
- * demux layer. It is only of interest for Digital TV device driver writers.
- * The header file for this kABI is named demux.h and located in
- * drivers/media/dvb-core.
- *
- * The demux kABI should be implemented for each demux in the system. It is
- * used to select the TS source of a demux and to manage the demux resources.
- * When the demux client allocates a resource via the demux kABI, it receives
- * a pointer to the kABI of that resource.
- *
- * Each demux receives its TS input from a DVB front-end or from memory, as
- * set via this demux kABI. In a system with more than one front-end, the kABI
- * can be used to select one of the DVB front-ends as a TS source for a demux,

- * The functions that implement the abstract interface demux should be defined
- * static or module private and registered to the Demux core for external
- * access. It is not necessary to implement every function in the struct
- * &dmx_demux. For example, a demux interface might support Section filtering,
- * but not PES filtering. The kABI client is expected to check the value of any
- * function pointer before calling the function: the value of NULL means
- * that the function is not available.
- *
- * Whenever the functions of the demux API modify shared data, the
- * possibilities of lost update and race condition problems should be
- * addressed, e.g. by protecting parts of code with mutexes.
- *
- * Note that functions called from a bottom half context must not sleep.
- * Even a simple memory allocation without using %GFP_ATOMIC can result in a
- * kernel thread being put to sleep if swapping is needed. For example, the
- * Linux Kernel calls the functions of a network device interface from a
- * bottom half context. Thus, if a demux kABI function is called from network

- *
- * This kernel-space API comprises the callback functions that deliver filtered
- * data to the demux client. Unlike the other DVB kABIs, these functions are
- * provided by the client and called from the demux code.
- *
- * The function pointers of this abstract interface are not packed into a

- * registered and used independent of each other. As an example, it is possible
- * for the API client to provide several callback functions for receiving TS
- * packets and no callbacks for PES packets or sections.
- *
- * The functions that implement the callback API need not be re-entrant: when
- * a demux driver calls one of these functions, the driver is not allowed to
- * call the function again before the original call returns. If a callback is
- * triggered by a hardware interrupt, it is recommended to use the Linux
- * bottom half mechanism or start a tasklet instead of making the callback
- * function call directly from a hardware interrupt.
- *
- * This mechanism is implemented by dmx_ts_cb() and dmx_section_cb()
- * callbacks.

+The reason why cec.c is still in staging is that I would like
+to have a bit more confidence in the uABI. The kABI is fine,
+no problem there, but I would like to let the public API mature
+a bit.
+
+Once I'm confident that I didn't miss anything then the cec.c source
+can move to drivers/media and the linux/cec.h and linux/cec-funcs.h
+headers can move to uapi/linux and added to uapi/linux/Kbuild to make
+them public.
+
+Hopefully this will happen later in 2016.
+
+Other TODOs:
+
+- Add a flag to inhibit passing CEC RC messages to the rc subsystem.
+  Applications should be able to choose this when calling S_LOG_ADDRS.
+- Convert cec.txt to sphinx.
+- If the reply field of cec_msg is set then when the reply arrives it
+  is only sent to the filehandle that transmitted the original message
+  and not to any followers. Should this behavior change or perhaps
+  controlled through a cec_msg flag?
+- Should CEC_LOG_ADDR_TYPE_SPECIFIC be replaced by TYPE_2ND_TV and TYPE_PROCESSOR?
+  And also TYPE_SWITCH and TYPE_CDC_ONLY in addition to the TYPE_UNREGISTERED?
+  This should give the framework more information about the device type
+  since SPECIFIC and UNREGISTERED give no useful information.

-Driver general quality is not good enough for mainline. Also, other
-device drivers (USB-bridge, tuner) needed for Astrometa receiver in
-question could need some changes. However, if that driver is mainlined
-due to some other device than Astrometa, unrelated TODOs could be
-skipped. In that case rtl28xxu driver needs module parameter to prevent
-driver loading.
-
-Required TODOs:
-* missing lock flags
-* I2C errors
-* tuner sensitivity
-
-*Do not* send any patch fixing checkpatch.pl issues. Currently it passes
-checkpatch.pl tests. I don't want waste my time to review this kind of
-trivial stuff. *Do not* add missing register I/O error checks. Those are
-missing for the reason it is much easier to compare I2C data sniffs when
-there is less lines. Those error checks are about the last thing to be added.
-
-Patches should be submitted to:
-linux-media@vger.kernel.org and Antti Palosaari <crope@iki.fi>

+ * struct cec_msg - CEC message structure.
+ * @ts:		Timestamp in nanoseconds using CLOCK_MONOTONIC. Set by the
+ *		driver. It is set when the message transmission has finished
+ *		and it is set when a message was received.
+ * @len:	Length in bytes of the message.
+ * @timeout:	The timeout (in ms) that is used to timeout CEC_RECEIVE.
+ *		Set to 0 if you want to wait forever. This timeout can also be
+ *		used with CEC_TRANSMIT as the timeout for waiting for a reply.
+ *		If 0, then it will use a 1 second timeout instead of waiting
+ *		forever as is done with CEC_RECEIVE.
+ * @sequence:	The framework assigns a sequence number to messages that are
+ *		sent. This can be used to track replies to previously sent
+ *		messages.
+ * @flags:	Set to 0.
+ * @rx_status:	The message receive status bits. Set by the driver.
+ * @tx_status:	The message transmit status bits. Set by the driver.
+ * @msg:	The message payload.
+ * @reply:	This field is ignored with CEC_RECEIVE and is only used by
+ *		CEC_TRANSMIT. If non-zero, then wait for a reply with this
+ *		opcode. Set to CEC_MSG_FEATURE_ABORT if you want to wait for
+ *		a possible ABORT reply. If there was an error when sending the
+ *		msg or FeatureAbort was returned, then reply is set to 0.
+ *		If reply is non-zero upon return, then len/msg are set to
+ *		the received message.
+ *		If reply is zero upon return and status has the
+ *		CEC_TX_STATUS_FEATURE_ABORT bit set, then len/msg are set to
+ *		the received feature abort message.
+ *		If reply is zero upon return and status has the
+ *		CEC_TX_STATUS_MAX_RETRIES bit set, then no reply was seen at
+ *		all. If reply is non-zero for CEC_TRANSMIT and the message is a
+ *		broadcast, then -EINVAL is returned.
+ *		if reply is non-zero, then timeout is set to 1000 (the required
+ *		maximum response time).
+ * @tx_arb_lost_cnt: The number of 'Arbitration Lost' events. Set by the driver.
+ * @tx_nack_cnt: The number of 'Not Acknowledged' events. Set by the driver.
+ * @tx_low_drive_cnt: The number of 'Low Drive Detected' events. Set by the
+ *		driver.
+ * @tx_error_cnt: The number of 'Error' events. Set by the driver.

-/**
- * DOC: Media Controller
- *
- * The media controller userspace API is documented in DocBook format in
- * Documentation/DocBook/media/v4l/media-controller.xml. This document focus
- * on the kernel-side implementation of the media framework.
- *
- * * Abstract media device model:
- *
- * Discovering a device internal topology, and configuring it at runtime, is one
- * of the goals of the media framework. To achieve this, hardware devices are
- * modelled as an oriented graph of building blocks called entities connected
- * through pads.
- *
- * An entity is a basic media hardware building block. It can correspond to
- * a large variety of logical blocks such as physical hardware devices
- * (CMOS sensor for instance), logical hardware devices (a building block
- * in a System-on-Chip image processing pipeline), DMA channels or physical
- * connectors.
- *
- * A pad is a connection endpoint through which an entity can interact with
- * other entities. Data (not restricted to video) produced by an entity
- * flows from the entity's output to one or more entity inputs. Pads should
- * not be confused with physical pins at chip boundaries.
- *
- * A link is a point-to-point oriented connection between two pads, either
- * on the same entity or on different entities. Data flows from a source
- * pad to a sink pad.
- *
- *
- * * Media device:
- *
- * A media device is represented by a struct &media_device instance, defined in
- * include/media/media-device.h. Allocation of the structure is handled by the
- * media device driver, usually by embedding the &media_device instance in a
- * larger driver-specific structure.
- *
- * Drivers register media device instances by calling
- *	__media_device_register() via the macro media_device_register()
- * and unregistered by calling
- *	media_device_unregister().
- *
- * * Entities, pads and links:
- *
- * - Entities
- *
- * Entities are represented by a struct &media_entity instance, defined in
- * include/media/media-entity.h. The structure is usually embedded into a
- * higher-level structure, such as a v4l2_subdev or video_device instance,
- * although drivers can allocate entities directly.
- *
- * Drivers initialize entity pads by calling
- *	media_entity_pads_init().
- *
- * Drivers register entities with a media device by calling
- *	media_device_register_entity()
- * and unregistred by calling
- *	media_device_unregister_entity().
- *
- * - Interfaces
- *
- * Interfaces are represented by a struct &media_interface instance, defined in
- * include/media/media-entity.h. Currently, only one type of interface is
- * defined: a device node. Such interfaces are represented by a struct
- * &media_intf_devnode.
- *
- * Drivers initialize and create device node interfaces by calling
- *	media_devnode_create()
- * and remove them by calling:
- *	media_devnode_remove().
- *
- * - Pads
- *
- * Pads are represented by a struct &media_pad instance, defined in
- * include/media/media-entity.h. Each entity stores its pads in a pads array
- * managed by the entity driver. Drivers usually embed the array in a
- * driver-specific structure.
- *
- * Pads are identified by their entity and their 0-based index in the pads
- * array.
- * Both information are stored in the &media_pad structure, making the
- * &media_pad pointer the canonical way to store and pass link references.
- *
- * Pads have flags that describe the pad capabilities and state.
- *
- *	%MEDIA_PAD_FL_SINK indicates that the pad supports sinking data.
- *	%MEDIA_PAD_FL_SOURCE indicates that the pad supports sourcing data.
- *
- * NOTE: One and only one of %MEDIA_PAD_FL_SINK and %MEDIA_PAD_FL_SOURCE must
- * be set for each pad.
- *
- * - Links
- *
- * Links are represented by a struct &media_link instance, defined in
- * include/media/media-entity.h. There are two types of links:
- *
- * 1. pad to pad links:
- *
- * Associate two entities via their PADs. Each entity has a list that points
- * to all links originating at or targeting any of its pads.
- * A given link is thus stored twice, once in the source entity and once in
- * the target entity.
- *
- * Drivers create pad to pad links by calling:
- *	media_create_pad_link() and remove with media_entity_remove_links().
- *
- * 2. interface to entity links:
- *
- * Associate one interface to a Link.
- *
- * Drivers create interface to entity links by calling:
- *	media_create_intf_link() and remove with media_remove_intf_links().
- *
- * NOTE:
- *
- * Links can only be created after having both ends already created.
- *
- * Links have flags that describe the link capabilities and state. The
- * valid values are described at media_create_pad_link() and
- * media_create_intf_link().
- *
- * Graph traversal:
- *
- * The media framework provides APIs to iterate over entities in a graph.
- *
- * To iterate over all entities belonging to a media device, drivers can use
- * the media_device_for_each_entity macro, defined in
- * include/media/media-device.h.
- *
- * 	struct media_entity *entity;
- *
- * 	media_device_for_each_entity(entity, mdev) {
- * 		// entity will point to each entity in turn
- * 		...
- * 	}
- *
- * Drivers might also need to iterate over all entities in a graph that can be
- * reached only through enabled links starting at a given entity. The media
- * framework provides a depth-first graph traversal API for that purpose.
- *
- * Note that graphs with cycles (whether directed or undirected) are *NOT*
- * supported by the graph traversal API. To prevent infinite loops, the graph
- * traversal code limits the maximum depth to MEDIA_ENTITY_ENUM_MAX_DEPTH,
- * currently defined as 16.
- *
- * Drivers initiate a graph traversal by calling
- *	media_entity_graph_walk_start()
- *
- * The graph structure, provided by the caller, is initialized to start graph
- * traversal at the given entity.
- *
- * Drivers can then retrieve the next entity by calling
- *	media_entity_graph_walk_next()
- *
- * When the graph traversal is complete the function will return NULL.
- *
- * Graph traversal can be interrupted at any moment. No cleanup function call
- * is required and the graph structure can be freed normally.
- *
- * Helper functions can be used to find a link between two given pads, or a pad
- * connected to another pad through an enabled link
- *	media_entity_find_link() and media_entity_remote_pad()
- *
- * Use count and power handling:
- *
- * Due to the wide differences between drivers regarding power management
- * needs, the media controller does not implement power management. However,
- * the &media_entity structure includes a use_count field that media drivers
- * can use to track the number of users of every entity for power management
- * needs.
- *
- * The &media_entity.@use_count field is owned by media drivers and must not be
- * touched by entity drivers. Access to the field must be protected by the
- * &media_device.@graph_mutex lock.
- *
- * Links setup:
- *
- * Link properties can be modified at runtime by calling
- *	media_entity_setup_link()
- *
- * Pipelines and media streams:
- *
- * When starting streaming, drivers must notify all entities in the pipeline to
- * prevent link states from being modified during streaming by calling
- *	media_entity_pipeline_start().
- *
- * The function will mark all entities connected to the given entity through
- * enabled links, either directly or indirectly, as streaming.
- *
- * The &media_pipeline instance pointed to by the pipe argument will be stored
- * in every entity in the pipeline. Drivers should embed the &media_pipeline
- * structure in higher-level pipeline structures and can then access the
- * pipeline through the &media_entity pipe field.
- *
- * Calls to media_entity_pipeline_start() can be nested. The pipeline pointer
- * must be identical for all nested calls to the function.
- *
- * media_entity_pipeline_start() may return an error. In that case, it will
- * clean up any of the changes it did by itself.
- *
- * When stopping the stream, drivers must notify the entities with
- *	media_entity_pipeline_stop().
- *
- * If multiple calls to media_entity_pipeline_start() have been made the same
- * number of media_entity_pipeline_stop() calls are required to stop streaming.
- * The &media_entity pipe field is reset to NULL on the last nested stop call.
- *
- * Link configuration will fail with -%EBUSY by default if either end of the
- * link is a streaming entity. Links that can be modified while streaming must
- * be marked with the %MEDIA_LNK_FL_DYNAMIC flag.
- *
- * If other operations need to be disallowed on streaming entities (such as
- * changing entities configuration parameters) drivers can explicitly check the
- * media_entity stream_count field to find out if an entity is streaming. This
- * operation must be done with the media_device graph_mutex held.
- *
- * Link validation:
- *
- * Link validation is performed by media_entity_pipeline_start() for any
- * entity which has sink pads in the pipeline. The
- * &media_entity.@link_validate() callback is used for that purpose. In
- * @link_validate() callback, entity driver should check that the properties of
- * the source pad of the connected entity and its own sink pad match. It is up
- * to the type of the entity (and in the end, the properties of the hardware)
- * what matching actually means.
- *
- * Subsystems should facilitate link validation by providing subsystem specific
- * helper functions to provide easy access for commonly needed information, and
- * in the end provide a way to use driver-specific callbacks.
