hardware acceleration on allwinner A10/A20 with vdpau and OpenGLES (zero-copy)
I don't have a 4k display, therefore I can't tell anything to that configuration. Only that 4k decoding is not supported by A20.
But the configuration fb0_framebuffer_num = 2 is correct, you need 2 buffers for double buffering.

The memory allocation for CMA is important, but there is no change required to what we already discussed in this thread (min 128MB for CMA).
