前端使用jsmpeg+websocket播放（4-9）个监控视频出现严重卡顿情况

Question

3个以上监控同时播放导致视频延迟严重，卡顿严重。使用stop(）方法停止一部分监控，情况会减轻。
前端具体代码：

监控1

<canvas></canvas>

Answer 1

<div class="main-item" >
       <p>监控1</p>
       <div>
           <canvas></canvas>
       </div>
   </div> 
    <script src="./js/jsmpeg.min.js"></script>
    <script type="text/javascript"> 
    let listEl = document.getElementsByClassName('main-item');
    for (let i = 0; i < listEl.length; i++) {
        let canvas = listEl[i].getElementsByClassName('canvas')[0];
        let port = canvas.getAttribute('prop-port');
        let url = 'ws://192.168.1.106:8088';
        _this._players[i] = new JSMpeg.Player(url, {
            canvas: canvas,
            disableGl: false
        });
    } 
    </script>
