See this example on webcam capturing in python

问题

When I run this script on my machine ( ubuntu 10.04 32 bit ):

http://pygstdocs.berlios.de/pygst-tutorial/webcam-viewer.html

I click on "Start" button and then I get this error:

# python example-webcam.py 
example-webcam.py: Fatal IO error 0 (Success) on X server :0.0.

Why ?
