Include CoglGst
CoglGst is a GStreamer integration library that facilitates video playback using the Cogl API. It works by retrieving each video frame from the GStreamer pipeline and attaching it to a Cogl pipeline in the form of a Cogl texture along with possible color model conversion shaders. The pipeline is then retrieved by the user during each draw. An example use of the CoglGst API is included in the examples directory.
