Stefano, thanks for useful hints. Is there some more detailed
documentation (than man 1 mplayer) about shared memory interface with
corevideo? How should I get frame size, pixel format, etc? From
mplayer stdout?
Or some code that can be looked at? Does MPlayer OSX Extended or
MPlayerX use this way of presenting video?
