/**
 * An example of how to stream a media file using RTP and use the "duplicate" output to also display
 * the video locally in an embedded media player.
 * <p>
 * Note that the duplicated output does not play it's own <em>stream</em>, so video displayed by
 * client applications will lag the local duplicated output.
 * <p>
 * The client specifies an MRL of <code>rtp://@230.0.0.1:5555</code>
