Gstreamer application using Qt

[Luca Santini]

If you only need a music/video player or camera capture and eventually 
plans to use QML, QtMultimediaKit is your way. you can implement a 
player with a single line of QML code...

Video { source: "myvideo.avi" }

But if you need more power (custom pipelines, capture from v4l2 generic 
devices etc.) this is definitively not the way to go: you need to link 
directly to gstreamer (as per Cedric example). The only side effect is 
you'll need some "major" tweaks to use it in QML (of course, only if you 
need it).
