[FFmpeg-devel] [PATCH v6 02/11] avcodec: add cbs for H266/VVC
Thomas Siedel
thomas.ff at spin-digital.com
Fri Feb 10 19:40:57 EET 2023
From: Nuo Mi <nuomi2021 at gmail.com>
Add CodedBitstreamContext to parse VPS,SPS,PPS in VVC nal units.
Implement parsing and writing of SPS,PPS,VPS,PH,AUD,SEI and slices.
Add ff_cbs_type_h266 to cbs types tables and AV_CODEC_ID_H266
to cbs codec ids.
