+This is an example of how to use Playbin, and send its output somewhere other
+than local video/audio playback.
+
+Using the 'video-sink' and 'audio-sink' properties, different ends of the Playbin
+pipeline can be set.
+
+Try experimenting with the 'DISABLE_VIDEO' and 'DISABLE_AUDIO' constants below.
+When set to true, they allow the Playbin sink to be set to 'fakesink', which
+stops them from playing locally.
