[Bf-committers] can we update ffmpeg to have RTSP support?

What if the Blender game engine receives only a very simple 
(uncompressed pixel?) stream from a fifo and an external program 
converts the required format? Or instead of a fifo, maybe it is possible 
to use shared memory mapping.

I'm sure it is possible in Linux but perhaps not in Windows. Is the game 
engine able to do this?
