+ * The fakesrc element is a multipurpose element that can generate

+ *
+ * It is mostly used as a testing element, one trivial example for testing
+ * basic <application>GStreamer</application> core functionality is:
+ *
+ * <refsect2>
+ * <title>Example launch line</title>
+ * |[
+ * gst-launch -v fakesrc num-buffers=5 ! fakesink
+ * ]| This pipeline will push 5 empty buffers to the fakesink element and then
+ * sends an EOS.
