--- Comment #15 from Nicolas Dufresne (ndufresne) <nicolas at ndufresne.ca> ---
Just to recap our IRC discussion, V4L2 Kernel API does not any API that really
match this. There is ways that user space could tell it's preferred stride,
with guaranty it will be used. UVC driver does not implement that (even though
it's doable). Downstream, in every cases, should be ready to copy (fallback
path) if the incoming alignment or stride does not match it's own requirement.
