<a name="gst-plugins-good-plugins-jackaudiosrc.description"></a><h2>Description</h2>
<p>A Src that inputs data from Jack ports.</p>
<p>It will create N Jack ports named in_&lt;name&gt;_&lt;num&gt; where
&lt;name&gt; is the element name and &lt;num&gt; is starting from 1.
Each port corresponds to a gstreamer channel.</p>
<p>The samplerate as exposed on the caps is always the same as the samplerate of
the jack server.</p>
<p>When the <a class="link" href="gst-plugins-good-plugins-jackaudiosrc.html#GstJackAudioSrc--connect" title="The “connect” property"><span class="type">“connect”</span></a> property is set to auto, this element
will try to connect each input port to a random physical jack output pin. </p>
<p>When the <a class="link" href="gst-plugins-good-plugins-jackaudiosrc.html#GstJackAudioSrc--connect" title="The “connect” property"><span class="type">“connect”</span></a> property is set to none, the element will
accept any number of output channels and will create (but not connect) an
input port for each channel.</p>
<p>The element will generate an error when the Jack server is shut down when it
was PAUSED or PLAYING. This element does not support dynamic rate and buffer
size changes at runtime.</p>
