[FFmpeg-devel] [PATCH v3 0/7] APV support

[Mark Thompson <sw@jkqxz.net>]

v3:
* Updated to match specification v4 (released a week ago).  Main change is the bitstream signature which is mandatory and helpfully makes probing a lot easier.
* Demuxer changed to use bytestream (thanks to Andreas for his comments).
* Improvements to AVX2 code (thanks to James for his comments).
* Decoder metadata support (not well-tested, need proper samples).
* Raw muxer added for easier testing (round-trip through cbs is the identity).
* Some other minor changes.

Thanks,

- Mark
