I don't think there's any reason mediainfo[1] 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.
Thanks,
Richard
