<title>GStreamer Standard Elements</title>
<para>
libgstelements.la provide some basic elements like a disk source
and sink. The use of these elements is strictly though the gtk_object_get() and
gtk_object_set() functions and the GStreamer Core Library functions.
</para>
<para>
Use the gst_elementfactory_find() and gst_elementfactory_create() functions
to create these elements.
</para>
<para>
The following code example shows you how to create a GstDiskSrc element.
