From: Niklas Haas <git@haasn.dev> To allow internally re-using it for both the encoder and decoder. This is based on HEVC only, H.264/AV1 use their own (hopefully correctly signalled) profiles (and in particular, the AV1 decoders implicitly default the correct profile in the absence of a configuration record). --- libavcodec/dovi_rpu.c | 4 ++-- libavcodec/dovi_rpu.h | 11 +++++++++++ 2 files changed, 13 insertions(+), 2 deletions(-)
