I'm starting to like the idea of the application creating an excessively
large buffer for OSD.  It will still need to check MPlayer's stdout to
know what dimensions the overlay is, but the buffer is fixed and can be
reused across invocations, and it solves the atexit problem.

I think the biggest video MPlayer can play is 2000x2000, so a buffer
that's 2000*2000*4 is 16M.
