Ah - Farkas Levente is a well-known name around the EL community, but that repo is not among those on the CentOS Repositories page.

Thanks for reporting back. Marking this thread [SOLVED] for posterity.

Yes, you can mark the post as SOLVED. I install libv4l-0.4.2-1.i386.rpm from here!.

Please let us know if you are confident the problem has been resolved, and where you got libv4l, so the issue can be marked appropriately.

I think I resolved the problem. Just remove kmod-video4linux and dkms packages and install libv4l - restart and now the cam works.

OK! Yesterday the cam with skype just worked. I reinstall packages like kmod-video4linux, dkms-x.x.x.x.x.el5.noarchI, I also installed and driver for my NVIDIA and I don't know what is happened but the camera just worked. Today I push my computer and find that the camera doesn't work again :( I am so confused! I tried to reinstall kmod-video4linux, dkms-x.x.x.x.x.el5.noarchI packages again but nothing. Everything I see when try to put my camera is

# gstreamer-properties

It seems the first thing to do is to fix the problem with Skype. If it is crashing it doesn't matter if the camera is working or not.

Hey, guys! Where are you? Please help me. I tried a various of methods but nothing. The strange is I tried again System ---> Preferences ---> More Preferences ---> Multimedia Systems Selector and the video just worked with v4l plugin. But the problem with the skype remains. And now when I tried to test the video from skype options the skype just closes itself. When I start Skype from console when the program is crashed i see this:

$ skype 
Segmentation fault

Any idea?

I installed Kopete in CentOS 5 but the camera doesn't work too neither in Skyper nor in Kopete. In Kopete I see only black screen and the LED indicator of the camera shows that the camera works.

Those seem to be mutually contradictory statements.

Hmm. The correct driver is present and loaded. It could be that the camera is outputting data in a format that the test software cannot understand.

Did you try with the original Video for Linux (v4l)?

Assuming you use a Gnome desktop then, while running kernel-ml-2.6.39-4.1.el5.elrepo, take the following sequence for testing --

System ---> Preferences ---> More Preferences ---> Multimedia Systems Selector

Now select the Video tab, set the Default Input Plugin to Video for Linux 2 (v4l2) and left-click on Test. If the correct driver has been selected and loaded, you should see a test display showing the image that the camera is capturing.

I'd go with the LiveDVD unless you have a reason to do otherwise - more features.

Whilst running kernel-ml-2.6.39-4.1.el5.elrepo, what does the following command line show --

grep -i 0ac8 /lib/modules/*/modules.alias | grep -i 303b

The gspca_zc3xx module, perhaps? If so, is it loaded?

/sbin/lsmod | grep gspca_zc3xx

I installed kernel-ml. First I had the problem with startX and I had to uninstall Nvidia driver to be able to startX.

I success startx without Nvidia driver. Now I tried camera with Skype but it still doesn't work. Is it possible to be a problem that the system starts without Nvidia driver or doesn't matter?
