opencv and v4l [was Re: Anyone got qc-usb working with kernel 2.6.28 and amd64?]
Turns out that the camera mostly works (camorama and v4lgrab.c both work, xinetv doesn't) seems that just opencv won't work with the camera with and error HIGHGUI ERROR: V4L: device /dev/video0 is unable to capture video memory. any ideas on what could this be?

Anyone got qc-usb working with kernel 2.6.28 and amd64?
I'm trying to get a Logitech, Inc. QuickCam Web (lego webcam based on logitec) working on my box running kernel 2.6.28 amd64 kernel. I managed to fix compilation errors using a patch I found on the bug tracking system plus some extra modifications. The resulting driver loads and recognizes the camera but xawtv doesn't give any output (black screen), the test program that comes with driver gives zeros for mem_map mode, it does seem to give and image for read mode. I also tried a sample program with opencv which complains HIGHGUI ERROR: V4L: device /dev/video0 is unable to capture video memory. I can't downgrade the kernel since I need the newest e1000e for my network card (anything older and the network card isn't supported).
