* GstPlay is a simple class for audio and video playback.
* It's job is to get the media (supplied by a URI) played.
* More specific it should get the media from source to the output elements.
* How that is done should not be relevant for developers using this class.
* A user using this class should not have to know very much about how
* GStreamer works, other than that it plays back media.
* Additionally it supplies signals to get information about the current
* playing state.
