Comment (by Tjoppen):
I took a quick look at both files using mxfdump. Some dark metadata indeed
gets lost after remuxing. The original file also uses a
!CDCIEssenceDescriptor with a !JPEG2000PictureSubDescriptor, while the
output of ffmpeg has no !JPEG2000PictureSubDescriptor. The errors about
zero BER length also seem relevant.
Getting the output of mxfenc.c to be in line with what metafier expects is
likely to take a bit of effort, since these analyzers tend to be picky. It
is certainly doable however, I've done similar things in the past. Would
you be willing to finance such an effort?
