 Summary of the bug:
 Movflags write_colr not working for Prores encoded mov files. Works with
 h264 encoding. Output shows the color metadata to be written, but it's not
 readable with ffprobe or ffmpeg, or any other software. Doesn't seem to
 work in 4.1, 4.2 or git-master, but works in 4.0.
 How to reproduce:
 {{{
 ffmpeg -f lavfi -i testsrc=duration=10:size=1920x1080:rate=24000/1001
 -pix_fmt yuv422p10le -colorspace bt709 -color_primaries bt709 -color_trc
 bt709 -movflags write_colr -c:v prores_ks -profile:v hq testsrc.mov

 ffprobe -i testsrc.mov -show_streams

 ffmpeg version 4.1.4
 }}}

 Patches should be submitted to the ffmpeg-devel mailing list and not this
 bug tracker.
