Comment (by Djfe):
someone just informed me, that the file I uploaded doesn't contain any
information about which color matrix it conforms to.
FFmpeg obviously guessed BT.709 since it's a full hd video.
But in fact it was BT.601
The only issue I can see here, is that FFmpeg has to guess the color
matrix, but doesn't warn the user about that.
But the original issue might be a different one, so don't close this, yet
;)
