<h1>Live<a class="headerlink" href="#live" title="Permalink to this headline">¶</a></h1>

<p>A typical live source is UDP multicast, which is the only live protocol

packager supports directly right now.</p>

<p>UDP file is of the form udp://ip:port[?options]. Here is the list of supported
|
|
options:</p>
