To: ffmpeg-devel; +Cc: Nuo Mi, Thomas Siedel
From: Thomas Siedel <thomas.ff@spin-digital.com>
Add muxer for vvcc byte stream format.
Add AV_CODEC_ID_VVC to ff_mp4_obj_type.
Add AV_CODEC_ID_VVC to ISO Media codec (VvcConfigurationBox vvi1,
vvc1 defined in ISO/IEC 14496-15:2021).
Add VvcConfigurationBox vvcC which extends FullBox type in
ISO/IEC 14496-15:2021.
Tested with:
ffmpeg -i NovosobornayaSquare_1920x1080.mp4 -c:v libvvenc test.mp4 && ffmpeg -i test.mp4 -f null -
ffmpeg -i NovosobornayaSquare_1920x1080.mp4 -c:v copy test.mp4 && ffmpeg -i test.mp4 -f md5 -

To: ffmpeg-devel; +Cc: Nuo Mi, Thomas Siedel
From: Thomas Siedel <thomas.ff@spin-digital.com>
Add transport stream stream type 0x33 for vvc.
Add STREAM_TYPE_VIDEO_VVC to MPEG-1/2 and MPEG-2 transport stream.
Add basic transport stream support for TS mux/demux.
Tested with:
ffmpeg -i NovosobornayaSquare_1920x1080.mp4 -c:v libvvenc test.ts && ffmpeg -i test.ts -f null -
ffmpeg -i NovosobornayaSquare_1920x1080.mp4 -c:v copy test.ts && ffmpeg -i test.ts -f md5 -
