SAM9x5 v4l2 video output for Mplayer


The SAM9x5 parts with a LCD controller have an overlay layer which supports some hardware acceleration for video playback.
Those functions (color space conversion, alpha blending, scaling) are highly CPU consuming and video playback can be really accelerated when they are performed by hardware.

MPlayer is a famous free and open source media player and is available on many different operating systems including Linux and especially for embedded Linux.
