--- Comment #27 from Nicolas Dufresne (stormer) <nicolas.dufresne at collabora.co.uk> ---
Interesting, I had this reflection that the stride alignment was incompletly
applied.

I think doing so in the pools is best. Note that set_video_alignment() can't
really change the alloc params silently, as for most base class the parameters
need to be updated in the query, otherwise they get reset.

We are missing patches for the glpool, which is different. No need for a loop
in this case, since we have N allocation, just pick the max between the
parameters et de shocked stride align.

It's also likely xnimagesink need to be checked.
