--- Comment #20 from Nicolas Dufresne (stormer) <nicolas at ndufresne.ca> ---
All those patches are wrong, because the CAPS arrives before the segment. The
test dec->input_segment.format will always be undefined until you re-negotiate.
Combine with the poor quality of the parser (which call memory_map/unmap
multiple time for the same buffer), this cause a massive performance regression
with v4l2src/dmabuf jpegs.
