[FFmpeg-user] xyz to rgb conversion

I too am in need of raw XYZ output from a DCI MXF and I tested output to a
TIFF file since that would allow for XYZ colour space without the need to
convert to Rec.709 RGB. However, the output TIF seems to always be RGB
Rec.709.

Is there any way to disable the automatic conversion from XYZ to RGB when
decoding JPEG2000?

The command line I used was:
ffmpeg -i videofile.MXF -pix_fmt xyz12le -f image2 -vframes 1 output.tiff

The output.tiff is in RGB Rec.709.

I used the Sep 18 ffmpeg build.

Thanks anyone that can help!
