<a name="gst-plugins-bad-plugins-mplex.description"></a><h2>Description</h2>
<p>
This element is an audio/video multiplexer for MPEG-1/2 video streams
and (un)compressed audio streams such as AC3, MPEG layer I/II/III.
It is based on the <a class="ulink" href="http://mjpeg.sourceforge.net/" target="_top">mjpegtools</a> library.
Documentation on creating MPEG videos in general can be found in the
<a class="ulink" href="https://sourceforge.net/docman/display_doc.php?docid=3456&amp;group_id=5776" target="_top">MJPEG Howto</a>
and the man-page of the mplex tool documents the properties of this element,
which are shared with the mplex tool.

<div class="refsect2" title="Example pipeline">
<a name="id504643"></a><h3>Example pipeline</h3>
<div class="informalexample"><pre class="programlisting">
gst-launch -v videotestsrc num-buffers=1000 ! mpeg2enc ! mplex ! filesink location=videotestsrc.mpg
</pre></div> This example pipeline will encode a test video source to an
MPEG1 elementary stream and multiplexes this to an MPEG system stream.
<p>
If several streams are being multiplexed, there should (as usual) be
a queue in each stream, and due to mplex' buffering the capacities of these
may have to be set to a few times the default settings to prevent the
pipeline stalling.
