does it display an image, iow does cheese work before you try to quit? I think you might be hitting a known libv4l bug, please try this libv4l update: http://koji.fedoraproject.org/koji/buildinfo?buildID=72926 Please let us know if this update fixes this. No, it doesn't work. The update doesn't fix this. Hmm, Ok, I *think* that you've got the logitech cam with the manufacture:device id of: 046d:09a6 You can confirm this by running the "lsusb" command in a terminal. If this is the case, chances are you've got a cam with a hardware bug, see: http://www.quickcamteam.net/hcl/linux/logitech_device_list_v2.pdf And notice how this cam has footnote 7: "7 Incompatibilities with some USB controllers on Linux. The camera may hang when starting the stream multiple times. This affects cameras with the USB BCD 0x0009" please run: lsusb -d 046d:09a6 -v | grep bcdDevice If the output is 0.09, your cam has the hardware bug, for more on this see: http://www.quickcamteam.net/documentation/faq/how-many-versions-of-the-quickcam-pro-9000-are-there. --- The uvcvideo driver in kernels >= 2.6.27.5-121, has a workaround for a similar bug in other model camera's which might work here too. To try this, make sure you are running a kernel >= 2.6.27.5-121. If you need to update your kernel for that, please first check if the update itself fixes things and then as root do: rmmod uvcvideo modprobe uvcvideo quirks=64 Let me know if that helps. Yup, sure enough. That's it. I tried kernel-2.6.27.7-134.fc10 from updates-testing and the problem went away. (In reply to comment #4) > Yup, sure enough. That's it. > > I tried kernel-2.6.27.7-134.fc10 from updates-testing and the problem went > away. Thats good news! Did you need to use "modprobe uvcvideo quirks=64", or did it work right away ? I want to know because if you needed the quirsk=64 option then I will add your cam to the list of cams with quirks so that this happens automatically. It Just Worked; I didn't need the quirks=64 option. I don't think I'm getting the 30 fps at 640x480 that this camera is supposed to be capable of (and quirks=64 doesn't apper to help with this); but I am getting the higher resolution that the camera can do (1600x1200). Ok, thanks. Closing this then :) |
