<para>
This library provides a Manager that maintains a list of dynamically
controlable parameters for a GstElement.
Just think of a volume slider in a mixer.
</para>
<para>
To use this library one needs to add some code to initialize it.
<example>
<title>Adding the control library to a project</title>
<programlisting>
...
&hash;include &lt;gst/gst.h&gt;
&hash;include &lt;gst/control/control.h&gt;
...
gst_init(&amp;argc,&amp;argv);
gst_control_init(&amp;argc,&amp;argv);
...
</programlisting>
</example>
The next step is to get hold of the GstDParamManager instance of a GstElement.
