Hans V/Hans G,

There's a nasty bug at qv4l2 or at libv4l: it is not properly updating 
all info, if you change the video device. On my tests with uvcvideo (video0) 
and a gspca camera (pac7302, video1), it was showing the supported formats
for the uvcvideo camera when I changed from video0 to video1.

The net result is that the image were handled with the wrong decoder
(instead of using fourcc V4L2_PIX_FMT_PJPG, it were using BGR3), producing
a wrong decoding.

Could you please take a look on it?

Cheers,
Mauro
