* Make the "default" string a valid device name that has the same effectratchov2012-05-235-15/+29

| | | | | | | | | | | | | | | | single aucat instance to handle all audio and MIDI services. Since this partially breaks compatibility, this is a opportunitiy to fix few other design mistakes (eg ':' being used by inet6, type name vs api name confusion, etc..). This leads to the following names: type[@hostname][,unit]/devnum[.option] The device number is the minor device number for direct hardware access (ie the 'N' in /dev/audioN). For aucat, this is the occurence number of the -f (or -M) option. There's a compatibility hook to keep old names working if only one aucat server is running.

| | | | | | | | | with almost the same syntax (roughly an extra -M option). Thru boxes are created with aucat, and corresponding MIDI port names have the "aucat" prefix instead of "midithru". The old device name will still work some time for backward compatibility. ok deraadt

| | | | | | | | | | | | | | | | | | | work over TCP, for instance, to expose the sound card of one machine with other machines of the network. The first client generates a 128-bit random number (aka the session cookie), saves it in $HOME/.aucat_cookie and sends it to the server. Successive clients load the cookie from $HOME/.aucat_cookie and send it to the server but the server accepts only clients whose cookie matches the session cookie. When all clients are gone, the session is over, and another cookie could start a new session, and so on. TCP is enabled on the server with the new -L option, and on the client side hostnames are specified with a new optional component in the device name. hints from damien, dlg and deraadt, tweaks from jmc

* remove aucat(1) and midicat(1) socket paths from the FILES sections.ratchov2011-04-161-9/+3
| | | | | Besides being wrong, they are part of sndio internals and don't need to be exposed in such a high level man page.
* for unix domain socket addresses use AUCAT_PATH and MIDICAT_PATHratchov2011-04-162-5/+5

| | | | | | with the server. As we're at it use the same protocol for midi and audio. Now, both audio and midi code use the same SNDIO_DEBUG environment variable to turn on/off DPRINTF's.

* don't try to get the current stream postion when the device is stopped,ratchov2010-09-171-9/+9

* polish the code: remove few unused #includes, add missing ones,ratchov2010-08-201-2/+5
| | | | fix NULL vs 0, etc. No behaviour change.
* If audio interrupts are missed (as this happens on some MP systemsratchov2010-08-061-18/+22
| | | | | | | | | | | | | | | now), play and record directons may be out of sync, and since the play direction is used as clock source, we may end up with data ariving _before_ the time it was recorded. This breaks the sndio ``device model'' and most full-duplex apps relying on it, starting with aucat in its default mode. Workaround this by using the direction that's ahead as clock source, ensuring that recorded data never arrives before the clock tick it was recorded. This prevents apps from crashing but won't fix stuttering caused by missed interrupts. ok deraadt@

* add two new members to structs audio_encoding and audio_prinfo.jakemsr2010-07-151-7/+7
| | | | | | | | | | for both structs, the new members are 'bps' and 'msb', which describe the number of bytes per sample and data alignment in the sample, respectively. drivers must properly set these fields in the 'query_encoding', 'set_parameters' and 'get_default_params' hardware interface methods. discussed with ratchov, deraadt
* Handle all streams the same way because there's no actualratchov2010-07-061-4/+18
| | | | | | | | | | | | difference between audio files and client connections. Clean up the way command line options are handled and clarify this in the manual page: stream parameters (-Ccehjmrtvx) must precede stream definitions (-ios) and per-device parameters (-abz) and stream definitions (-ios) must precede device definitions (-f). Since there's no ``server'' and ``non-server'' modes anymore, make the -l option just detach the process. ok and help from jakemsr and jmc
* don't prime server buffers, because it's ugly and conceptuallyratchov2010-06-051-4/+6

* Don't send the initial position as a clock tick with a negative delta.ratchov2010-06-051-9/+12

| | | | | | | full-duplex, we may detect a xrun in the play direction and discard the clock tick, this would cause sio_revents() to return POLLIN without the clock being advanced, causing apps relying on the clock for flow control to enter a busy loop.
