docs: Send an output frame.
  
          The frame is sent to each input the output is connected to. If
          there are no connections this is a null operation with little
          overhead.
  
          :param str output_name: the output to use. Must be a member of
              :py:attr:`~Component.outputs`.
  
          :param Frame frame: the frame to send.
