    <p>Hi all</p>
    <p>Does webrtcbin 1.19.2 allow a sequence like this, adding video
      after connection is established?</p>
    <ol>
      <li>open peer connection (with offer from remote browser client)<br>
      </li>
      <li>wait for signalling to reach stable state</li>
      <li>add new elements to the pipeline supply video to the <i>webrtcbin</i>
        element<br>
      </li>
      <li>re-negotiate connection by sending new offer to client &
        wait for answer<br>
      </li>
      <li>profit</li>
    </ol>
    <p>It seems that it should do, but I've had not much success making
      it work.  Sometimes the video will appear in the browser client,
      but at extremely low, intermittent 1-5 fps</p>
    <p>Also, should adding elements to the pipeline automatically
      trigger the <i>on-negotiation-needed</i> event<i>?</i><br>
    </p>
    <p>cheers<br>
