We could force the application to run -identify on the files in the
playlist beforehand, and setup a shm buffer large enough to accommodate
the largest overlay.

Your alternative suggestion (MPlayer creates the buffer but the
application destroys it) is a bit cumbersome, because what if a
subsequent file requires a new buffer?  In that case, MPlayer will
destroy the old one and create a new one.  So then the design would be
that MPlayer creates and destroys all buffers except for the last one,
which is the app's responsibility.  That's very sloppy, IMO.
