Not all status changes where reported and setting the QCamera to LoadedState was not actually loading anything. State and status changes have been refactored. Camera status is now reported directly by the camera session. Setting the camera state to LoadedState now sets the camerabin to GST_STATE_READY, that allows to query for camera capabilities without having to start the camera (and have a valid viewfinder).
