Well, I'm still a newbie and I'm not sure I fully understand what you 
suggested... Anyway I'm going to try it and if I still have some doubts 
I'll come back here :-)

About gstreamer-1.0. I'm using gstreamer in Qt, and there is no 
qt-gstreamer-1.0 currently, afaik. So I'm stuck with gstreamer-0.10...

I'm sorry, I wasn't talking about switching the source on-the-fly. I'd 
like to have a working pipeline and change the source at compile time.

I'm studying that chapter and the others. The difficult ("my" difficult) 
is the guide doesn't explain when and why use an element rather than 
another. It just defines them.
