I know why you are doing this (and I recommended it often) 
but it makes detection of xyz impossible.

We should probably work on this but I suspect the easiest 
solution is to compile without "--disable-encoder" and 
specify the decoder you want:
$ ffmpeg -vcodec libopenjpeg -i input.mxf
This will use the internal decoder only to decide the 
pix_fmt but will use the (bitexact!) libopenjpeg 
decoder for actual decoding.
