Hi Claudio ...

I'll look into patching ffplay.c with my OpenGL changes and submitting 
the code once I've gotten the direct rendering problem sorted out.

I am aware of the performance loss caused by OpenGL. It was chosen over 
overlays because it makes adding in special effects much easier, 
especially time critical stuff.
