handoff

handoff_callback (GstElement * object,
                  GstBuffer * buffer,
                  gpointer udata)

def handoff_callback (object, buffer, udata):
    #python callback for the 'handoff' signal

function handoff_callback(object: GstElement * object, buffer: GstBuffer * buffer, udata: gpointer udata): {
    // javascript callback for the 'handoff' signal
}

This signal gets emitted after rendering the frame.
