When creating MOV files, setting the -color_range option does not seem to have
any effect. What am I doing wrong? Could it have anything to do with the
removal of the yuvj pixel formats?
Is setting this metadata even possible in the MOV container, or is it something
that is expected to be flagged at the stream level? I was having difficulty
finding info on where this info is even located in a file in both:
https://developer.apple.com/library/archive/technotes/tn2162/_index.html and
https://developer.apple.com/library/archive/documentation/QuickTime/QTFF/QTFFPreface/qtffPreface.html
Worrying, if I set a value of jpeg, mpeg, or 0, ffprobe says that the file has
TV range.
How to replicate:
$ ./ffmpeg -f lavfi -i testsrc -color_range jpeg -c:v prores -t 1

However, when setting the same flag '-color_range jpeg' using Matroska,
mediainfo picks up on the colour range flag, but ffprobe still says tv:
