This is needed to handle differing API requirements (e.g. libx265 requires the NAL RBSP, but CBS BSF requires the unescaped bytes). --- libavcodec/dovi_rpu.h | 16 ++++++++++------ libavcodec/dovi_rpuenc.c | 22 ++++++++++------------ libavcodec/libaomenc.c | 3 ++- libavcodec/libsvtav1.c | 3 ++- libavcodec/libx265.c | 2 +- 5 files changed, 25 insertions(+), 21 deletions(-)
