You don't mention which image you're using as your base.

You probably need to increase the CMA allocation on the kernel command line.

Running "dmesg | grep -i CMA" will likely give you the information you need.

Also note the rpi media offload stuff isn't yet upstream so won't work
to do HW accelerated video decode.
