[FFmpeg-devel] [PATCH v2] avcodec/hevc/ps: add a range check for sps_max_sub_layers

It can't be higher than vps_max_sub_layers. Do this while keeping the workaround for qsvenc_hevc calling ff_hevc_parse_sps() without a vps_list, as in some cases it needs to parse an sps to generate a fake vps derived from it. Signed-off-by: James Almer --- libavcodec/hevc/ps.c | 9 +++-- 1
