Comment:
Yeah, absolutely. There are so many things going on in terms of HDR but no
one in the ffmpeg community seems to care. So when I have to deal with HDR
content, I just think "oh shit, no way, this is not going to work", then I
will look for the same content in SDR format, so that I can convert it to
my desired format. It's lower quality for sure but at least it will be
played as intended by the creator. As an alternative you could just leave
the HDR content untouched which may waste disk space. This is sad. ffmpeg
is all about converting from one format to the other, but when HDR videos
is involved, the best thing is to just not convert it. Then ffmpeg will be
obsolete. So I think this is even critical. It is a substantial thread to
ffmpeg itself. If ffmpeg will not be able to deal with HDR, there will be
no use case for ffmpeg in the future. It will be a relic of the past, when
people still used SDR. This is the most critical thing I can imagine.
Also it is sad to see that the system still works as before. People just
submit code based on what they think is best for them or what made the
most fun to code but still no one tries to balance forces and to
incentivize people to do actual needed things.
