Comment (by Balling):
It will never be obsolete, because Nvidia (nvenc) and Intel (mediasdk) are
supporting it. Again we need to first implement dynamic metadata then we
can see and look what metadata should be preserved. Also please don't
forget that ffmpeg is a library. One should preserve only such values that
could not usually change (it is right with tags (like MP3)) and many other
stuff, like HDR metadata inside (!) frames. But outside metadata can
change and you must understand that the part of the program which is doing
that is not ffmpeg, it is h265 codec.
