/**
* The #GstControlSource is a base class for control value sources that could
* be used to get timestamp-value pairs. A control source essentially is a
* function over time.
*
* A #GstControlSource is used by first getting an instance of a specific
* control-source, creating a binding for the control-source to the target property
* of the element and then adding the binding to the element. The binding will
* convert the data types and value range to fit to the bound property.
*
* For implementing a new #GstControlSource one has to implement
* #GstControlSourceGetValue and #GstControlSourceGetValueArray functions.
* These are then used by gst_control_source_get_value() and
* gst_control_source_get_value_array() to get values for specific timestamps.
