if we use libva in embeded env,there is a GPU and video accelerate module on soc ,what should i do to use libva to accelerate video decode or encode? I know that the answer is the drive in user mode,and i know the process in pc is libva ->drm->|drm in kernel->driver in kernel mode.but now i want run libva in embeded system,so how to make it in all process from kernel mode driver to user mode driver and libva in user mode? thanks a lot
