<body>

<video controls ondurationchange="myFunction()">
  <source src="video.mp4" type="video/mp4">
  <source src="video.ogg" type="video/ogg">
  Your browser does not support HTML5 video.
</video>/*w  ww.  j a  v  a2  s .c o  m*/

<p id="demo"></p>
<script>
function myFunction() {
  document.getElementById("demo").innerHTML = "The video duration has changed";
}
