This was solved by setting the CMA pool at a fixed address in that range. However, in recent kernels there's something else that comes in and reserve some range that end up conflicting with our default pool requirement, and thus makes its reservation fail. The video codec will then use buffers from the usual default pool, outside of the range it can access, and will fail to decode anything. Since we're only concerned about that 256MB, we can however relax the allocation to just specify the range that's allowed, and not try to enforce a specific address.
