Has anyone got GStreamer and camera to work on Harmattan (N950) devices? I tried to follow the example for Maemo  (converted to Qt) but I could not get it working (it compiles of course but fails to show the camera viewfinder or record video).
I also included the AEGIS permissions manually and tried different video sources (auto, subdev, ...) all without success.
Then there is another nice interface to gStreamer for Qt "Qt-GStreamer" (http://gstreamer.freedesktop.org/wiki/QtGStreamer) with a sample application "Recorder". This application shows an error message "Cannot open /dev/video0".
The Qt mobility project also uses gStreamer for camera/video.
