[FFmpeg-devel] [PATCH v2 09/13] lavc/vaapi_hevc: Add vaapi profile parse support for SCC

Fei Wang fei.w.wang at intel.com
Mon Dec 5 08:09:25 EET 2022


From: Linjie Fu <linjie.fu at intel.com>

Note that Screen-Extended Main 4:4:4 and 4:4:4 10 supports
chroma_format_idc from 0, 1 or 3, hence both 420 and 444 are
supported.
