Here is what I told Richard:

Look at the "MediaPlayer" example: you can play any video files (or 
sound files)  with it.

It is based on the gb.media component which is a simplified interface to 
the GStreamer multimedia library.

That library (and so gb.media) works by putting "plugins" together. It's 
like Legos.

The MediaPlayer is based on a big GStreamer plugin that implements a 
full media player.

Hopefully, GStreamer has a plugin named "v4l2src" that gets images from 
a Video4Linux device.

So, by replacing the "file" input plugin by the "v4l2src" plugin in the 
MediaPlayer, you can see your webcam anywhere on the screen.

It should be just a matter of setting the right properties of the 
"v4l2src" plugin. Google and a little elbow grease should help there.

If someone has more time than me *and* a webcam to test if the gb.v4l 
component can easily be replaced by gb.media, it would be cool! :-)
