<h1>Packager Documentation<a class="headerlink" href="#packager-documentation" title="Permalink to this headline"></a></h1>
<p>Shaka Packager is a tool and a media packaging SDK for DASH and HLS packaging
and encryption. It can transmux input media files from one container to another
container.</p>
<div class="admonition note">
<p class="first admonition-title">Note</p>
<p class="last">Shaka Packager does not do transcoding. Content must be pre-encoded before
passing to packager.</p>
</div>
<p>Packager operates in <em>streams</em>, described by <em>stream_descriptor</em>. The streams
can be read from the same “file” or different “files”, which can be regular
files, pipes, udp streams, etc.</p>
<p>This page is the documentation on using the <em>packager</em> tool. If you are
interested in integrating <em>packager</em> library into your own tool, please see
<a class="reference internal" href="library.html"><span class="doc">Shaka Packager Library</span></a>.</p>
