Comment (by Balling):

 Okay, I think you are right. Thought metadata insertion is not the first
 priority, we should add support for Atmos, Dolby Vision ICtCp
 https://github.com/sekrit-twc/zimg/issues/117 and HDR10+ (both encoding in
 h.265 (just activate it in h.265 encoder) and decoding with already
 present patches https://patchwork.ffmpeg.org/patch/11828/, etc). Those
 codecs require dynamic metadata manipulation, so we will need it or ask
 this guy https://github.com/rigaya/NVEnc/issues/119. After that we can do
 (and finally consider) what metadata and when should be the default.
