Comment (by mario66):

 Libav was focused on getting things right before working on fancy new
 stuff. This was the absolute correct thing to focus on. Unfortunately, it
 got abandoned because, like I said, doing things right doesn't attract
 developers. It's the fancy new stuff that attracts developers, because
 they just want to have fun while coding. This is how "open source
 development" always works. Libav was the rare exception but too few people
 followed them. It's so sad. I would definitively use it if it was actively
 developed, this I can tell you.

 HDR is just not usable with ffmpeg because of this. It was not developed
 until the end. Probably something more fancy was on the way.

 "ffmpeg HDR metadata" is the among the top 4 (!) suggestions in Google if
 you type "ffmpeg HDR". Because everyone who wants to encode HDR will
 stumble across this. HDR is already in the mass marked. Even cheap TV
 supports it. I would consider this as a major drawback of ffmpeg that it
 cannot properly handle HDR. And I am sure some people haven't even noticed
 but they will screwed once they find out that in their media backup
 collection important metadata is missing.

 I'm just telling the truth.
