There's also issues with structure changes which won't be caught that 
way. libwmapro sounds like the sanest solution, short of doing the same 
thing with Wine.

Cool, I didn't know about libwmapro. It does look like exactly what we
need, but I'm concerned about it being so out of date. ffmpeg's wma
files alone have over 400 commits since 2011.

I don't know what was added later in ffmpeg but libwmapro definitely plays
WMA files on my Sansa Clip+ running RockBox 3.13.

This is what I would do:

   - Take libwmapro as-is to replace the ffmpeg dependency in your xinput2
   implementation

   - If something is missing, or does not work as expected, contact the
   libwmapro maintainers and ask them why they haven't kept up to date with
   ffmpeg. Maybe those changes are only adaptations to new ffmpeg APIs, or
   unimportant changes. And maybe they will even say "it's a good idea,
we'll
   look into updating libwmapro"

   - If everything else fails, take ffmpeg and spend a non-negligible
   amount of time isolating a "libwinewma", which you'll have to
maintain
   yourself and everything in the future.
