[FFmpeg-user] How can I set in a D10 MXF (IMX50) file the flags for output color_range, -space, -transfer and primaries?

Wed Apr 29 23:22:14 CEST 2015

I found out that a IMX50 mxf file encoded with FFmbc and the IMX50 mxf file encoded with actual ffmpeg builds are different in these mxf metadata flags (by reading out via ffprobe - show_streams)

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

FFMPEG IMX FILE stream 0:0:
color_range=tv
color_space=unknown
color_transfer=unknown
color_primaries=unknown

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 :/

Best Regards
CHristoph
