title: Single Manifest file for different audio and video segments created using MP4Box (MPEG DASH)
body: <p>I have three questions</p>
  
  <p>1) Does dash.js support audio and video content multiplexed in a single segment?</p>
  
  <p>2) If not how to merge audio.mpd and video.mpd created using MP4Box into a single out.mpd, that is supported by dash.js player?</p>
  
  <p>3) It works if AdaptationSet is copied manually from audio.mpd and placed in video.mpd and video.mpd is played using dash.js. How to automate it?</p>
  
  <pre><code>MP4Box -dash 4000 -frag 4000 -rap -bs-switching no -profile dashavc264:live -segment-name ./video/segment_ -out video.mpd video.mp4#video
