VAAPI buffer alignment

[xrataj00]

Hello,

I have a pipeline that ends like this:

vaapipostproc ! video/x-raw,format=BGRx ! appsink

It is producing buffers with align=0. Is it possible to change the
allocation params to make buffers with align=7? I am playing with
GST_QUERY_ALLOCATION in appsink pad probe callback but no luck so far. Any
ideas? 

Thanks
Tomas.
