Hi Doug, yup that's looking better, normal CIF this time... V4L2: start V4L2: format cifdecimate: 2 V4L2: setting input port to 0 V4L2: setting format: width=352 height=288

Hi Doug, I'm running FC8 on i386 I'll also have a dig around see if there's any Creative cam's around the place. All this is for a small AG 'piggy' node setup in a spare office across the hall from our larger AG venue. To be used when there's only one or two bods booked for AG sessions. I'll probably endup dual-booting Win/Linux, I'm doing the Linux one first because the hardware can be tricker to setup.

Which Fedora 8 are you running (i386 or x86-64)? I'll build a RPM for you to test out. I like the Creative Live UVC cameras as they support uncompressed video for the common resolutions.

Thanks Doug, it looks like the closest YUYV mode is 176x144. Is there a way I can use the MJPEG stream? Otherwise, my next question is... are there recommended USB cam's for Linux?

If I run 'luvcview' I can get something that resembles 352x288/CIF although i'm not sure what size it is exactly! 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.
