title: How to use HTTP Live Streaming's EXT-X-MEDIA?
body: <p>I'm currently working on a project that has been filmed several times during the year, at different seasons.</p>
  <p>The different video tracks are time synced, so I'd like to take advantage of HTTP Live Streaming's <strong><a href="https://datatracker.ietf.org/doc/html/draft-pantos-http-live-streaming-07#section-3.3.9" rel="nofollow noreferrer">EXT-X-MEDIA</a></strong> to let the users switch between seasons on iOS-devices.</p>
  <p>I've setup an M3U8 playlist containing the video, but I can't seem to expose the <em>controls</em> in the Quicktime player – neither on the iPhone nor the iPad.</p>
  <p>Here's my playlist:</p>
  <pre><code>#EXTM3U
  #EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID=&quot;500kbs&quot;,NAME=&quot;Winter&quot;,AUTOSELECT=YES,DEFAULT=YES
  #EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID=&quot;500kbs&quot;,NAME=&quot;Spring&quot;,AUTOSELECT=NO,DEFAULT=NO,URI=&quot;spring.m3u8&quot;
  #EXT-X-MEDIA:TYPE=VIDEO,GROUP-ID=&quot;500kbs&quot;,NAME=&quot;Summer&quot;,AUTOSELECT=NO,DEFAULT=NO,URI=&quot;summer.m3u8&quot;
  
  #EXT-X-MEDIA:TYPE=AUDIO,GROUP-ID=&quot;aac&quot;,LANGUAGE=&quot;eng&quot;,NAME=&quot;English&quot;,AUTOSELECT=YES, \
  DEFAULT=YES,URI=&quot;audio.m3u8&quot;
  #EXT-X-STREAM-INF:PROGRAM-ID=1,BANDWIDTH=754857,VIDEO=&quot;500kbs&quot;,AUDIO=&quot;aac&quot;,CODECS=&quot;avc1.42e01e,mp4a.40.2&quot;
  ./winter.m3u8
  </code></pre>
  <p>Shouldn't this work?</p>
