* Demo application for librygel-renderer-gst.
*
* Creates a simple stand-alone UPnP renderer that renders any visual content
* fullscreen.
*
* Usage:
* fullscreen-renderer [<network device>]
*
* If no network device is given on the commandline, the program falls back to
* eth0.
*
* To do anything useful, another UPnP server + UPnP controller is necessary
* to tell it which media file to show.
