The interface looked like a good idea around the time Clutter 0.2 was out, but in reality we never had a proper, and supported implementation outside of clutter-gst - thus, ClutterMedia was acting like a wrapper around GStreamer, leading to hilarious issues of impedence mismatch between API and all sorts of indirection issues typical of wrong abstractions. In theory, ClutterMedia should have been deprecated and removed before we hit 1.0, but we kept flip-flopping on the issue. For 2.0, it's time to take it out. And shoot it in the face.
