Hi Doug - just an update... video is still working fine with this USB cam. I've noticed that if I click on the Menu button in the main Vic window the colour saturation goes up to max, hitting Reset in the "Video4Linux2 grabber controls" pane (or sliding the saturation back to middle) takes the saturation back to normal. It's not a big problem, just took me a minute to figure out what was going weird with the image!

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.
