Even though the CODA h.264 decoder always decodes complete macroblocks, we can
set the stride to the corresponding multiple of 16 and use a value smaller than
that as real width. Unfortunately the same doesn't work for height, as there
is no vertical linesperframe stride for discontiguous planar YUV frames.
