* | lavd/v4l2: allow devices not implementing VIDIOC_G_PARMNiklas Söderlund2016-06-16
| | | | | | | | | | | | | | | | | | | | | | Not all v4l2 devices implement the VIDIOC_G_PARM ioctl. This patch allow ffmpeg to open such device and treat it the same as devices that do implement the ioctl but returns that it do not implement the V4L2_CAP_TIMEPERFRAME capability.

| * lavf: replace AVStream.codec with AVStream.codecparAnton Khirnov2016-02-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, AVStream contains an embedded AVCodecContext instance, which is used by demuxers to export stream parameters to the caller and by muxers to receive stream parameters from the caller. It is also used internally as the codec context that is passed to parsers. In addition, it is also widely used by the callers as the decoding (when demuxer) or encoding (when muxing) context, though this has been officially discouraged since Libav 11. There are multiple important problems with this approach: - the fields in AVCodecContext are in general one of * stream parameters * codec options * codec state However, it's not clear which ones are which. It is consequently unclear which fields are a demuxer allowed to set or a muxer allowed to read. This leads to erratic behaviour depending on whether decoding or encoding is being performed or not (and whether it uses the AVStream embedded codec context). - various synchronization issues arising from the fact that the same context is used by several different APIs (muxers/demuxers, parsers, bitstream filters and encoders/decoders) simultaneously, with there being no clear rules for who can modify what and the different processes being typically delayed with respect to each other. - avformat_find_stream_info() making it necessary to support opening and closing a single codec context multiple times, thus complicating the semantics of freeing various allocated objects in the codec context. Those problems are resolved by replacing the AVStream embedded codec context with a newly added AVCodecParameters instance, which stores only the stream parameters exported by the demuxers or read by the muxers.

| * Deprecate avctx.coded_frameVittorio Giovara2015-07-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rationale is that coded_frame was only used to communicate key_frame, pict_type and quality to the caller, as well as a few other random fields, in a non predictable, let alone consistent way. There was agreement that there was no use case for coded_frame, as it is a full-sized AVFrame container used for just 2-3 int-sized properties, which shouldn't even belong into the AVCodecContext in the first place. The appropriate AVPacket flag can be used instead of key_frame, while quality is exported with the new AVPacketSideData quality factor. There is no replacement for the other fields as they were unreliable, mishandled or just not used at all. Signed-off-by: Vittorio Giovara <vittorio.giovara@gmail.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | As of September 14 2012, v4l_enumstd() will return ENODATA when a device's std field is set to 0. That is, the device does not have a standard format. In order to properly handle this case, v4l2_set_parameters should catch the ENODATA code and break instead of failing. Below is the v4l2-core commit describing this change. >>commit a5338190efc7cfa8c99a6856342a77d21c9a05cf >>Author: Hans Verkuil <hans.verkuil@cisco.com> >>Date: Fri Sep 14 06:45:43 2012 -0300 >> >> [media] v4l2-core: tvnorms may be 0 for a given input, handle that case >> >> Currently the core code looks at tvnorms to see whether ENUMSTD >> or G_PARM should be enabled.
