Hi Mark & all,
Happy new year!
I have implemented the h266 metadata bsf. For all vvdec decodable clips,
the metadata pass-through mode can get a bit matched result.
Could you align with James about the name convention, so I can send the
second patchset?
BTW: could you share the hevc aud adding command line?
I tried "ffmpeg -i input.265 -c:v copy -bsf h266_metadata -aud insert
output.265", but the output.265 has no aud.
thanks
