Now I try fswebcam$ -r 800x600 image.jpg
--- Opening /dev/video0...
Trying source module v4l2...
/dev/video0 opened.
No input was specified, using the first.
Adjusting resolution from 800x600 to 160x120.
--- Capturing frame...
Captured frame in 0.00 seconds.
--- Processing captured image...
Writing JPEG image to 'image.jpg'.
No matter what resolution I emter I get this message and the image file displays garbage except for the time/date banner at the bottom.
I've tried on two different systems with the same result and as usual ant info I find acts like you are already an expert on v4l. Which, I am not.
Any help greatly appreciated.
