I have a logitech quickcam chat that was working fine until I upgraded to Ubuntu 12.04.
I had to use preload v4l hack but since then it always worked for three consecutive ubuntu versions.
Now, when I start the webcam during a call, it works for a few seconds, then it freezes, sortof resets and starts updating the image every 5 seconds, like a slide show.
If I go to options and test the video it works fine. The webcam works fine as well with google talk.
Does anybody have the same problem?
