Public bug reported:
After putting karmic on my laptop, the webcam stopped working on cheese and
gstreamer-properties. It used to work fine under intrepid.
I went to the webcam help site, and i tried putting this in the terminal:
mplayer tv:// -tv driver=v4l2:width=640:height=480:device=/dev/video0
the webcam then started to work again and gave this output:
ha...@hamza-laptop:~$ mplayer tv:// -tv
driver=v4l2:width=640:height=480:device=/dev/video0
MPlayer UNKNOWN-4.4.1 (C) 2000-2009 MPlayer Team

HOWEVER when I exited the terminal and put it in again, it gave this:
