<video id="video" class="video-js vjs-default-skin" controls> //  replace these own video files.       <source src="video.m4v" type="video/mp4" />      html5 video required example. </video>  <audio id="myaudio" class="video-js vjs-default-skin"></audio>  <script> var player = videojs("myaudio", {     controls: true,     autoplay: true,     loop: false,     width: 600,     height: 300,     plugins: {         wavesurfer: {             src: "media/heres_johnny.wav",             msdisplaymax: 10,             wavecolor: "grey",             progresscolor: "black",             cursorcolor: "black",             hidescrollbar: true         }     } }); </script>
