dmesg after load uvcvideo with trace=0xfff

This dmesg output seems to indicate that the frame is propperly processed by uvcvideo, maybe this problem is in gst?

There is still no change up to today.

Is it only me who is affected?

Comment 3 Fabian Deutsch 2011-11-10 09:25:19 UTC
Okay, this seems to be a problem on the wnidow side, not the camera.
If I use a Clutter Texture to view the webcam picture, everything goes well. So this seems to be something on the sink side.
