There is a new overlay abstraction for hardware video planes in SurfaceFlinger. This code will be pushed out to android.git.kernel.org very soon. The code is not functional yet. There is just a few header files and some skeleton code in SurfaceFlinger, and nothing has been done yet in the media framework. However it should give you a good idea of where we are headed with the design.
