 Replying to [comment:2 heleppkes]:
 > The dolby vision enhancement layer doesn't actually use NAL units 63 and
 62,

 But have you read
 https://www.reddit.com/r/ffmpeg/comments/a32yv4/in_the_future_would_it_be_possible_to_remux_a/

 It is even more difficult, no?

 Besides that can you comment on
 https://bitbucket.org/multicoreware/x265/commits/all?search=dolby+vision
 They added support for dolby vision and hdr10+. What part of it is
 implemented and is "Dolby Vision Enhancement Layer" implemented?
 Are you going to support it? And in NVENC support also added:
 https://github.com/rigaya/NVEnc/issues/119

 Also I want to ask about this patch for ffmpeg
 https://patchwork.ffmpeg.org/patch/10708/
 It has new MKTAG('v','d','e','p'), so I suppose it is important. And this
 one?https://patchwork.ffmpeg.org/patch/11828/


 "It's still writing to an AVBufferRef in set_side_data() that may or may
 not be writable." And so what? Solve it and pull already.
