Consider adding vgmstream plugin
Please consider adding vgmstream as an official plugin
The project's upstream source is https://github.com/losnoco/vgmstream
I have been able to get this working on a Fedora 29 machine with relatively little effort.

The plugin is an input plugin which adds support for a number of obscure formats used by recent Nintendo consoles, GCN - WiiU.
People have ripped the tracks out of Super Smash Bros Brawl in particular, which was known for its large tracklist and soon began substituting other tracks in, which meant turning into a compatible format. Examples can be found at http://smashcustommusic.com/game/36
Notes on the license are currently at https://github.com/losnoco/vgmstream/blob/master/COPYING
I am not the author, I do not know how to contact users on github
Obscure formats which I do not believe are covered by ffmpeg are BRSTM, BCSTM, BFSTM
