I don't think there's any reason mediainfo can't go in Fedora, but I
figured the most likely user base would be here in RPM Fusion.
This has been a useful utility for me giving very detailed media
information and I'm considering submitting it for review anyway, but it
requires two other libraries that are not yet in Fedora and I've got enough
packages to take care of as it is.
That being said, if someone will help with the reviews and offer to
co-maintain, I'd consider submitting them for review.
