title: How to setup HLS and DVR functionality and read it?
body: <p>I want to create an audio stream live with the DVR functionality.</p>
  
  <p>In my player I want to listen live or seek the past stream (few minutes ago).</p>
  
  <p>I use nginx to serve the hls stream.
  How to setup the DVR functionality? Do I use a specific module in nginx for live stream and past stream with a param like past.m3u8?seek=timestamp</p>
  
  <p>I'm also looking for a web player in html5 and fallback in flash to read the live stream and can seek the past.m3u8 stream.</p>
