 Replying to [comment:2 heleppkes]:

 But have you read

 It is even more difficult, no?

 Besides that can you comment on
 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:

 Also I want to ask about this patch for ffmpeg
 It has new MKTAG('v','d','e','p'), so I suppose it is important. And this

 "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.
