<h3>Demo details</h3>
<p>This demo showcases the functionality provided by the Streaming plugin.
In particular, it provides three different streaming approaches, namely:</p>
<p><ol>
<li>An on-demand stream originated by a file (a song, in this case):
different users accessing this stream would receive a personal view
of the stream itself.</li>
<li>A pseudo-live stream, still originated by a file (an audio recording
of a radio running commentary): different users accessing this stream
would all receive the same, shared view of the stream.</li>
<li>A live stream, originated by a gstreamer script: as for the pseudo-live
stream, different users will get the same feed.</li>
</ol></p>
<p>You can try them all within the same session: just choose the stream
you're interested in and press the <code>Watch</code> button to start
the playout. Stopping it will allow you to switch to a different one.</p>
<p>Press the <code>Start</code> button above to launch the demo.</p>
