Last time I looked my webcam wasn't supported well/at all although
there was a driver. I found the graphics stuff to play with video
streaming very disjointed, hard to run/compile and generally not worth
the effort. 

e.g. barely available software A  depends on codecs B, C, or D &
E, and can use a binary G  with package F. Half a page of
aspirations as the docs :-/. 

I trust things have improved a little. If things have changed much, let 
us know!
