Summary0002846: Some perfectly playable files result in a "TrackType missing" exception
DescriptionI came across some releases, all by the same user, that cannot be dumped with avdump2 for some reason; they throw an exception with the text "Failed to create MatroskaProvider TrackType missing", which naturally leads to no dump being sent back to AniDB.

The releases in question are under this account:

The files can be played just fine in MPC-HC at the very least. Sorry that I can't narrow the problem further for you, not really sure what's so different about these as opposed to other Matroska files.

I would inspect the metadata provided by the MediaInfo utility ( Avdump2 uses the mediainfo library (though likely an older version).

Some metadata problems or other irregularities, or corruption, are worked around by media splitters, codecs, and players but still may stump Avdump2. Or, there could of course be a bug somewhere ;)

That's what I already checked before, but I guess I could add a sample output to this bug report for convenience.

I recently submitted files for 3 animes (12080, 13031, 12602) just like I always did. It took me some time to notice that while avdump2 actually finished like always, it didn't work.
At the end it said "Failed: 0" and created the ed2k I used for adding the files, but it didn't send the data in the background. If you expand the ADL releases, you'll see what I mean.
After looking around I found the error xml files it created, and they are all like the one below. Can anybody fix that so I can resubmit the files?

Tried to manually update the MediaInfo_x64.dll/MediaInfo_x86.dll libraries with the latest official ones, but it seems avdump2 hardcodes a dependency on old versions:
"Mediainfo library version mismatch. Needed: v0.7.42, Used: MediaInfoLib - v0.7.99"

obviously. we can't have users change the format willy nilly and mess with the expected data.

This issue was fixed by Avdump2 v7070+ at the start of the year, at least for the files I had problems with, so this should probably just be marked as resolved now.
