    thanks for your replay, But I had found this from DFM file and done it.

      

    <audio id="player" height="0px" src="files/beep-digital.mp3" style="display:none"></audio>
<div>
  <video id="video" width="100%" height="100%" style="border: 1px solid gray"></video>
</div>

<div id="sourceSelectPanel" style="display:none">
  <label for="sourceSelect">Change video source:</label>
  <select id="sourceSelect" style="max-width:400px">
  </select>
</div>
