Presence – always

Direction – sink

Object type – GstPad

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): {
