Is there a way to tell libv4l2 which native source format it should

YUYV and MJPG (see output below)

So it picks up YUYV as source format. I had a look at
v4lconvert_try_format but can see no way how to do this.
If I understand the source correctly the table at [1] is the brain of
the conversion. MJPEG has a rank of 7, YUYV has a rank of 5. So YUYV is
chosen. The function that picks the conversion path is at [2].
Currently there is no way to influence the decision. Why do you want to
do this?
Thanks,
Gregor
