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?

Thanks A couple of quick pointers to help you get more help: Looks like it's a hardware or driver problem as the camera is just not reporting that it has any capabilities. I hacked the code opencv code to ignore that and proceed blind and now it's working.
