                      GstBuffer * buffer,
                      GstPad * pad,
                      gpointer udata)

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

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

This signal gets emitted before unreffing the buffer.
