and then the Quickcam turns off and no video picture appears.  I can get the 9000 to work intermittently on Intrepid if I run luvcview which works fine, then gstreamer-properties and select the USB audio and UVC video.

The Mac quickcam exhibits the same behavior except that the video works in the test in gstreamer-properties (though it selects the max resolution of 1600x1200, so this appears to be a problem with how cheese is interpreting the capabilities information or it not setting up the audio correctly.




Steps to reproduce:
1. Connect webcam
2. Launch Cheese
3. 


Actual results:
See description

Expected results:
I would expect to get video.

Does this happen every time?
Yes.

Other information:
I will attach similar debug output from test with Quickcam 9000.
