Could you provide the output of 'luvcview -L' which list the available resolutions and pixelformats, I've appended the ouput from a Creative UVC webcam at the bottom of this email. > I've built the latest uvcvideo kernel module source from > http://linux-uvc.berlios.de/ > vic-2.8ucl1.4.0-0.1.20080714svn.fc8 > > V4L2: start > V4L2: format cifdecimate: 2 > V4L2: setting input port to 0 > V4L2: failed to set format! requested 352x288, got 176x144 It's the UVC driver, not VIC which selects 176x144 as the nearest resolution to 352x288, hopefully the 'luvcview -L' output will explain why.
