Comment (by Leo Izen):
Replying to [ticket:11443 Jay123210599]:
> I heard that if you add colorimetry flags to videos without them, or for
videos with colorimetry flags already present, if you make PNG files out
of it, the ffmpeg PNGs will display incorrect colors in many programs,
including browsers because of gAMA and cHRM tag issues. Is that true, and
if so, why? How do I fix it?
This is not true, so there's no need to fix it. If you have an actual PNG
that you believe is displaying incorrectly in a browser that is generated
by FFmpeg then you should open a separate issue. Preferably you should
only open issues if you have observed the bug, rather than "have heard"
about it.
