[FFmpeg-devel] [PATCH] HDR Transcode VUI Info Copy

This patch adds copy of HDR  VUI info from decode ctx to encode ctx. Currently, information under colour_description_present_flag (eg. colour primaries, transfer_characteristics, matrix_coeffs) do not get copied to output stream when trancode happens.

Testing performed:
ffmpeg.exe -y -hwaccel cuvid -vcodec hevc_cuvid -i input.h265 -vcodec hevc_nvenc output.h265
Ensure the output bitstream contains the same colour_description_present_flag fields as input.

Also attaching previous discussion on this subject.
