There are many tutorials how to show video from camera on screen (like this one). I need to modify video stream with simple but custom filter. Stream may be low-res, so CPU should have enough juice.
What is the best way to modify live video stream?

Self comment - Raspberry camera board seems to do some DMA to framebuffer trick, bypassing CPU. May bu quite hard then. – tomash Feb 7 '14 at 23:29
