## Signals

### create-element

    GstElement *
    create_element_callback (GstElement * object,
                             gpointer udata)

    def create_element_callback (object, udata):
        #python callback for the 'create-element' signal

    function create_element_callback(object: GstElement * object, udata: gpointer udata): {
        // javascript callback for the 'create-element' signal
    }

Will be emitted when we need the processing element/s that this bin will use
