Comment (by cehoyos):

 Replying to [comment:10 gemil]:
 > It looks like the first picture can be decoded, but something at the end
 of it makes the next picture and subsequent ones undecodable.

 The file format of the concatenated j2m file you uploaded is invalid and
 does not conform to any specification (to the best of my knowledge),
 Motion JPEG 2000 is defined as j2k in mov and (as far as decoding is
 concerned) supported by FFmpeg. I created ticket #5359 to allow decoding
 of such invalid files but this is completely unrelated to this ticket:
 Please explain what created the mxf file you uploaded. (Please do only
 explain it if you are interested in fixing your issue, if you are not
 interested in fixing it, do not explain anything.)
