title: Playing audio.mpd and video.mpd together in dash.js
body: <p>For MPEG DASH streaming, I have audio.mpd and video.mpd separately for a video.mp4 file generated using following command.</p>
  
  <pre><code>MP4Box -dash 5000 -frag 5000 -rap -bs-switching no -profile dashavc264:live -segment-name ./video/$2_segment_ -out ./mpds/$2_video.mpd $2.mp4#video
  
  MP4Box -dash 5000 -frag 5000 -rap -bs-switching no -profile dashavc264:live -segment-name ./audio/$2_segment_ -out ./mpds/$2_audio.mpd $2.mp4#audio 
  </code></pre>
  
  <p>Each mpd plays separately in dash.js. Is it possible to play them together using dash.js?</p>
  
  <p>Or is there any way to merge both using MP4Box?</p>
