Hello, I had this problem too. The right palette to use is VIDEO_PALETTE_JPEG if you are using the Labtec Webcam Pro with V4L. But the image captured seems not complete. The bottom of image was grey (there was an other post on that problem but I can't find it :s). I had many troubles to use this cam with V4L/V4L2. I manage to make it work very well on my laptop with V4L2 but not on the foxboard. My application crashes with V4L2 on the fox. I will give you more details tonight with my source code.
