Well, I don't think it is obvious that the metadata buffersize depends on the
video width. Perhaps developers who are experienced with CSI know this, but
if you know little or nothing about CSI, then it can be unexpected (hey, that
was the case for me!).
I think it doesn't hurt to mention this relation.
