This Week's Activity

avformat: add fields to AVProgram/AVStream for PMT change tracking
FFmpeg - Aman Gupta: These fields will allow the mpegts demuxer to expose details about the PMT/program which created the AVProgram and its AVStreams. In mpegts, a PMT which advertises streams has a version number which can be incremented at any time.

avformat/mpegts: add merge_pmt_versions option
FFmpeg - Aman Gupta: This new optional flag makes it easier to deal with mpegts samples where the PMT is updated and elementary streams move to different PIDs in the middle of playback. Previously, new AVStreams were created per PID, and it was up to the user to figure out which streams had migrated to a new PID (by iterating over the list of AVProgram and making guesses), and switch seamlessly to the new AVStream during playback. Transcoding or remuxing these streams with ffmpeg on the CLI was also quite painful, and the user would need to extract each set of PIDs into a separate file and then stitch them back together. With this new option, the mpegts demuxer will automatically detect PMT changes and feed data from the new PID to the original AVStream that was created for the orignal PID.

avfilter/vf_lut2: add timeline support to tlut2 filter
FFmpeg - Paul B Mahol

avformat/mpegts: parse sections with multiple tables
FFmpeg - Aman Gupta: Fixes PMT parsing in some mpegts streams which contain multiple tables within the PMT pid.

lavd/v4l2: Add ARGB and XRGB packed pixel formats
FFmpeg - Anton Leontiev: Formats ARGB32, XRGB32, ABGR32, and XBGR32 were added to V4L2 instead of ill-defined deprecated RGB32/BGR32 pixel formats. When pixel format is not specified explicitly FFmpeg tries formats in order in which they are stored in the table.

vaapi_encode_h265: Insert mastering display colour volume
FFmpeg - Haihao Xiang: '-sei xxx' is added to control SEI insertion, so far only mastering display colour volume is available for testing.

cbs_h265: read/write HEVC PREFIX SEI
FFmpeg - Haihao Xiang: Similar to H264, cbs_h265_{read, write}_nal_unit() can handle HEVC prefix SEI NAL units.
