I found out that a IMX50 mxf file encoded with FFmbc and the IMX50 mxf file

color_range=tv
color_space=smpte170m
color_transfer=bt709
color_primaries=bt470bg
FFMPEG IMX FILE stream 0:0:

I want to set these metadata flags to the same values, but with FFmpeg.
How can I produce the same output like ffmbc with these 4 metadata flags?
I didnt found a answer to that in the ffmpeg documentation :/
You can manually specify these settings to force them being set with these
parameters:
-color_primaries 5
-color_trc 1
-colorspace 6
What does not work as far as I know in ffmpeg is to actually get these
settings from the source video, even if ffprobe detects them.
