title: Kurento : Rewinding a live video stream
body: <p>I was wondering if we can rewind a live video stream or maybe use recorder endpoint to show a different video element on the screen and then rewind the video using recorder endpoint. Is it possible to achieve this by RecorderEndpoint or can it be achieved by writing some custom kurento module using some gstreamer plugins?</p>
  
  <p>Any help is much appreciated. </p>
