+ *
+ * The #GstControlSource is a base class for control value sources that could
+ * be used by #GstController to get timestamp-value pairs.
+ *
+ * A #GstControlSource is used by first getting an instance, binding it to a
+ * #GParamSpec (for example by using gst_controller_set_control_source()) and
+ * then by having it used by the #GstController or calling
+ * gst_control_source_get_value() or gst_control_source_get_value_array().
+ *
+ * For implementing a new #GstControlSource one has to implement a
+ * #GstControlSourceBind method, which will depending on the #GParamSpec set up
+ * the control source for use and sets the #GstControlSourceGetValue and
+ * #GstControlSourceGetValueArray functions. These are then used by
+ * gst_control_source_get_value() or gst_control_source_get_value_array()
+ * to get values for specific timestamps.
