Comment (by Arnaud):

 Replying to [comment:9 cehoyos]:
 > I did mention that I disagree with your assumption that I am able to
 reproduce the issue. But even if not, why should I have posted your
 (exact) command line with the actual console output (that differs from the
 one you posted)?

 My bad: I just read your comment and didn't have a look the the console
 output.

 > You didn't remember it when I told you that you have local patches
 applied?

 I thought by "local changes" you were referring to the workaround I've
 found (so my confusion)

 > Ideally you would send a patch (only the mxf.c part) made with {{{git
 format-patch}}} to the development mailing list.

 As you already submitted a patch ("Support more mxf files with codec_ul"
 if I'm right), do you think it's worth it?

 > Can you make the dvvideo sample available?

 Regarding the diff in riff.c? I don't know why we needed this, not sure if
 I have a sample. Will try to find one.
