[FFmpeg-devel] [PATCH 0/5] AV1 Annex B demuxer

[James Almer]

This includes a bitstream filter to merge Temporal Units split across different
AVPackets, given that Annex B encapsulation splits OBUs at the Temporal Unit,
Frame and OBU boundaries.
Bitstream reconstruction is required to prevent propagating AVPackets with
contents that could generate invalid files in other containers.

TODO: Changelog entries and lavc/lavf version bump.

James Almer (5):
  avcodec/cbs_av1: support one byte long OBUs when the size is not set
    in the bitstream
  avcodec: add an AV1 frame merge BSF
  avcodec/av1_parser: export bitstream timing info when available
  avcodec/libdav1d: export bitstream timing info when available
  avformat: add an AV1 Annex B demuxer
