Comment (by mario66):
Then the bug here is not fixed. It's as simple as that. You are telling a
lot of technical stuff about VLC, Google, Dolby Vision, FEL, MEL etc. And
of course I appreciate your technical expertise you donate to this
project. But I just want to be sure that we are on the same page. The page
where everyone should be is the bug I reported initially. For ffmpeg. Not
for any other application. This is the first step, this should be
prioritized. This is often the problem with ffmpeg that you do the second
step before the first step. HRD10+, Dolby Vision etc. Yes this is all
relevant for the future. But now I'm talking about a simple HDR10 static
metadata example. This is what's deployed in the real world now. This you
should now make rock solid. Then you can move to HDR10+ and Dolby Vision,
then 12 Bit or whatever. In this order. And then again you should keep
implementing all those features until they are rock solid.
If you continue with the current attitude we will have neither HDR10 nor
any advanced dynamic meta data HDR usable in the real world. Just people
who ''started'' to implement something that works under laboratory
conditions but never finish the actual integration for real world usage to
the end. This is the core problem here, in my opinion. Developers do the
first 80% of development, where it makes fun to code and you make a lot of
progress. Then, when it comes to completing the implementation and making
the software to work in the real world with all the little details you
have to consider, like to make sure not ''loose'' the meta data during
transcode, developers quickly loose interest...
