media: vidtv: fix decoding with gstreamer and Vlc

2020-10-01T07:24:54Z

Neither Vlc nor Gstreamer likes the PES_scrambling_control bits. In the case of GST, this can be seen with: $ GST_DEBUG=2 LANG=C gst-play-1.0 pcm_audio.ts ... 0:00:00.097973439 12308 0x55f7ddd155e0 WARN pesparser pesparse.c:411:mpegts_parse_pes_header: Wrong '0x10' marker before PES_scrambling_control (0x40) 0:00:00.097987026 12308 0x55f7ddd155e0 WARN tsdemux tsdemux.c:2314:gst_ts_demux_parse_pes_header: Error parsing PES header. pid: 0x111 stream_type: 0x6 ... So, change, it. After such change, the stream now plays fine with Vlc, Gstreamer, ffmpeg - and with programs that use such libraries, like Kaffeine. Signed-off-by: Mauro Carvalho Chehab

media: vidtv: rewrite the adaption field logic

2020-10-01T07:24:33Z

When compared with a stream generated via ffmpeg, it can be noticed that the PES doesn't contain any PCR info. That could cause problems with userspace decoding. So, rewrite the logic that fills the adaptation info, in order to allow it to add PCR frames without breaking frame alignment. Signed-off-by: Mauro Carvalho Chehab

media: vidtv: simplify parameters for vidtv_pes_write_stuffing()

2020-10-01T07:22:00Z

Instead of passing struct pes_ts_header_write_args fields as function parameters, just pass a pointer to the struct. That would allow adding more args without needing to change the function prototype. Signed-off-by: Mauro Carvalho Chehab

media: vidtv: cleanup PSI version numbers

2020-10-01T07:20:56Z

There's no reason to use static vars to store PSI version numbers. Also, currently, version numbers are starting with 0x01, because there's a code being called that increases it to 1 for all table initializer code, as the code may support dynamic changes at the PS tables on some future. So, let's just initialize them to 0x1f, in order for the versions to be reported as starting from 0. Signed-off-by: Mauro Carvalho Chehab

media: vidtv: fix initialization of the network_id field at SDT

2020-10-01T07:20:35Z

This field should point to the network ID, and has different ranges for cable, terrestrial or satellite. It also has an special range for temporary private usage. For now, let's use the temporary private one. Once the Network Information Table (NIT) gets added, this should be reviewed. Signed-off-by: Mauro Carvalho Chehab

media: vidtv: remove more ENDIAN_BITFIELD nonsense

2020-10-01T07:20:09Z

Changeset 870e350d4e39 ("media: vidtv: get rid of ENDIAN_BITFIELD nonsense") was incomplete. There are still some wrong endannes logic at the driver. Get rid of them. Signed-off-by: Mauro Carvalho Chehab

media: vidtv: simplify PCR logic to get jiffies

2020-10-01T07:19:48Z

There's no need to have a check when setting timing.past_jiffies, as we can simply do the initialization earlier at vidtv_mux_init(). Signed-off-by: Mauro Carvalho Chehab

media: vivid: Add support to the CSC API

2020-09-26T08:21:34Z

The CSC API (Colorspace conversion) allows userspace to try to configure the colorspace, transfer function, Y'CbCr/HSV encoding and the quantization for capture devices. This patch adds support to the CSC API in vivid. Using the CSC API, userspace is allowed to do the following: - Set the colorspace. - Set the xfer_func. - Set the ycbcr_enc function for YUV formats. - Set the hsv_enc function for HSV formats - Set the quantization for YUV and RGB formats.
