I tested this with this sample http://www.opencubetech.com/userdoc/mxf_samples_files/xdcamimx-30mbps-ntsc.mxf using ffmpeg 2.2.3.

If I run as suggested:
ffmpeg -i xdcamimx-30mbps-ntsc.mxf -c copy -bsf:v imx_dump_header xdcamimx-30mbps-ntsc.mov

Conversion failed!

I didn't see imx_dump_header in git. Is there a patch I'm missing? Also I don't think the original documentation would work in Final Cut properly unless you set the vtag to mx[3,4,5][n,p] as imx.
