Reverse-engineered VPU driver (CedarX) for AllWinner A10 plays mpeg1, mpeg2, H.264 with hardware acceleration as CNX-Software reports here:

Little more details can be found at the site of highly talented hackers who made it possible. Sure, it's still work in progress, and scaling of video to real device's screen resolution doesn't work just yet, but the proof of the concept is here:
Together with Lima open graphics driver for Mali 200, 400 series GPU which is incidentally more advanced than what manufacturers' binary blobs can offer, it's a great achievement on the path of open hardware movement. It also means that at one point the cheapest ($20...$30) single core Allwinner A10 powered HDMI sticks will run better, hardware accelerated Linux and XBMC than, say, more expensive quad-core RK3188 powered devices.
As these Allwinner A10 are way too weak to run full featured Linux, next targets for reverse engineers could be Allwinner A31 and Rockchip RK3188 chips (just a little of wishful thinking...)
