I think we should start by fixing the stride in the colorspace, then fix the
plugins that assume incorrect strides (maybe we should open another bug for that?).

For I420, the stride of the U and V plane is half the size of the Y plane. So,
for a width of 300, the stride of U and V will be 150. I don't know much about
the other YUV formats, but for U and V they all seem to use either half the size
or the full size of Y.
