This simple example program shows how to instantiate the renderer then configure its GStreamer playbin element and connect it to a network interface, rendering the content to stdout as ASCII.

/*
 * Demo application for librygel-renderer-gst.
 *
 * Creates a simple stand-alone UPnP renderer that renders any visual content
 * in ASCII-art using GStreamer's cacasink element.
 *
 * Usage:
 *   standalone-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.
