Yet, when I tried playing youtube videos in firefox nightly, they
played as normal.  I compile with cairo-gtk3 and with-X as options, so
maybe that has something to do with it.  But it doesn't make sense that
local players should have problems with local videos if firefox can play
remote videos.  For what it is worth, I also compile mplayer locally,
so it should be using the latest libraries too.

Puzzling.
