Sat Jan 27 06:15:12 EET 2024


From: Thomas Siedel <thomas.ff at 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 -
