It entirely depends on the vaapipostproc capability to honour such
alignment. But overriding the ALLOCATION query (e.g. using a pad
probe) and adding an allocation parameter to that query is the right
approach. If that does not give any result, then you'll have to dig
into vaapipostproc and see if there is a way to honour that suggested
alignment.
