I see, so that's why Fedora has mp4v2 while Mandriva has it in an
unofficial repository only.

OK, after looking at the implementation, it seems you are right:

MP4File::GetMetadataCoverArt extracts an image from the property
moov.udta.meta.ilst.covr.data[index].metadata, while
MP4File::SetMetadataCoverArt writes to
moov.udta.meta.ilst.covr.data.metadata only.

So there's room for improvement in the mp4v2 library.
