Why we should drop such useful app just because it doesn't work on Cinnamon? It works on GNOME without ffpmeg and rpm fusion repo, see screenshot [1].
Please prevent your useless app from displaying in cinnamon menu, I'm sure Mate, XFCE and LXDE would also like it removed from their menus as well.
Add this to it's desktop file!
'OnlyShowIn=Gnome'
