* @short_description: Push empty (no data) buffers around
* @short_description: Generate (meaningless) buffers
* @see_also: #GstFakeSink
*
* Dummy source that generates empty buffers.
* <refsect2>
* <para>
* The fakesrc element is a multipurpose element that can generate
* a wide range of buffers and can operate in various scheduling modes.
* </para>
* <para>
* It is mostly used as a testing element, one trivial example for testing
* basic <application>GStreamer</application> core functionality is:

* <title>Example launch line</title>
* <para>
* <programlisting>
* gst-launch -v fakesrc num-buffers=5 ! fakesink
* </programlisting>
* This pipeline will push 5 empty buffers to the fakesink element and then
* sends an EOS.
