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).

I was being stupid. It just iterates through the modes and uses the 1920x1080 below. I thought it tried the 3840x2160 from double framebuffer size, not thinking much (that it would be 4 times the 1920x1080...).
Anyway. I will fiddle around a little. Since I will be away for 10 days, it will be some time before I let you know if I progress

The library is included in the same repository. There was an dependency issue in the Makefile, please compile on a single core (i.e. don't use -j X). Then it should work.

if you mean the jarvis branch from my xbmc repository. Yes this one is stable, and the latest one using OpenGLES for displaying videos.
The latest development is master_allwinner_layered_vdpau, but this one is using an interface closer to the hardware for displaying videos. Gives better performance on FullHD resolutions.
