<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.

Use the gst_elementfactory_find() and gst_elementfactory_create() functions

to create these elements.

The following code example shows you how to create a GstDiskSrc element.
