    <style>
      .box {
        width:600px;
        height:400px;
      }
    </style> 
</head>
<body>
    <div class="box">
      <div id="Player"></div>
    </div>
    <script>
      // 例項化播放器
      var Player = new WasmPlayer(null,'Player',callbackFun,{cbUserPtr:this, decodeType:"auto", openAudio:1, BigPlay:false, Height:true});
      // 呼叫播放
      Player.play('影片流地址', 1);

      //播放事件回撥
      function callbackFun(e) {
        console.log(e)
      }
    </script> 
</body>
 
</html>

  </head>
  <body>
    <div id="app"></div>
  </body>
</html>
