I confirm this bug. I am using a Logitech QuickCam Pro for Notebooks with Jaunty on an HP xw4600 workstation. The camera works fine in other applications (Skype, guvcview). I always see one of the following behaviors.

1. The throbber throbs for awhile and then stops. During the throbbing I see that the camera is being probed for frame rates, capture sizes, etc. Once the throbbing stops, I am left with a blank image area. There is no "no webcam" message.

2. The throbber throbs. When the throbber stops, the video area shows the SMPTE test pattern. Again, there is no "no webcam" message.

3. The same as (2), except that the "no webcam" message actually does appear. This appears to be the rarest of these four cases.

4. The throbber throbs and then the camera works.

Sometimes, in the case of scenario (1), I can get the camera to work by going to preferences and changing the image size. If this does not work, a second attempt to change the video size will lock up the application.

I have tried the script running in a terminal as suggested in the comment of 2009-04-21, and this does not seem to make any difference. Doing cheese -v -gst-debug-level=3 only yields the warnings in the attached text file.

In general, when I have these problems I can successfully launch the web camera with the command:

gst-launch v4l2src ! 'image/x-raw-yuv,width=640,height=480,framerate=30/1' ! gconfvideosink.
