Summary of the bug:
In the recent versions the normalize video filter broke. Previously it
stretched the contrast, now it blows up the color space towards white.
Comparison with v4.2.2 can be found here: https://github.com/fourMs/MGT-
python/issues/145#issuecomment-713516121
How to reproduce:
{{{
% ffmpeg -i input normalize output
ffmpeg version 4.3.1
built on Windows 10
}}}
Patches should be submitted to the ffmpeg-devel mailing list and not this
bug tracker.
