 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-
 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
