Hi, This patch exports the full umid of packages as metadata. ffmpeg currently only exports the material number portion of the umid.
The new format is <ISO label>-<length>-<instance number>-<material number> example: 060a2b340101010101010f00-13-000000-53dc416b9a770251060e2b347f7f2a80 Some applications use the umids to link to mxf media instead using file paths. I've been using ffmpeg for some AAF work and have encountered MXF files with different ISO labels and having just the material number alone is not enough to link to media for Media Composer. For more on umids, this paper explains them pretty well http://www.digitalpreservationeurope.eu/publications/briefs/UMID_Unique%20Material%20Identifier.pdf umids also have a optional extened 32 bytes, but I've yet to see a file that has them.
