Hey Daniel, I haven't used libVLC before so I can't comment on using it with Qt. You can start here: http://wiki.videolan.org/LibVLC. I've used gstreamer before (only for audio), but there's an excellent Qt wrapper for gstreamer you can check out here if you're interested: http://gstreamer.freedesktop.org/wiki/QtGStreamer
