--- Comment #1 from Nicolas Dufresne (stormer) <nicolas at ndufresne.ca> ---
I figure-out that if videoconvert looks at video meta when selecting the
width/height it would fix this issue, because it would convert the full image.
Though, it would be inefficient, because cropping reduces the surface to
convert, and cropping is cheaper (it's "just" a smaller copy).

So I'm not completely certain which way, the fix is trivial both ways
(filter-out crop meta vs look at video meta width/height). If convertion is to
be done in software anyway, and cropping is small and handle without copy at
display, then this new approach would be better then dropping the meta.
