Hello, I have a server connected to a GoPro camera, which sends the images in base64 format, and can be seen on localhost, now I need to capture screenshot, but I can not, any ideas?

HTML

<html>
  <head>
    <title>Go Pro cliente</title>
    <script src="http://code.jquery.com/jquery-1.10.1.min.js"></script>
    <script type="text/javascript" charset="utf-8">
    var flag = false;
    var imgArray = new Array();


      $(document).ready(function(){
         if ("WebSocket" in window) {
            var ws_path = 'ws://' + window.location.host + window.location.pathname + 'ws';
            //alert(ws_path);
            var ws = new WebSocket (ws_path);
            //alert(ws);
            ws.onopen = function () {
               ws.send(1);
            };
            ws.onmessage = function (msg) 
            {
               $("#cam").attr('src', 'data:image/jpg;base64,' + msg.data);
                   if ( flag == true) 
                    {
                        $("#img").attr('src', 'data:image/jpg;base64,' + msg.data);
                        flag = false; 
                        var url = img.src.replace('data:image/jpg;base64,' + msg.data);
                    }
               ws.send(1);
            };
            ws.onerror = function (e) {
               console.log(e);
               ws.send(1);
            };
         } else {
             alert("WebSocket no soportado");
         }
      });

      function capture() 
      {
            flag = true;
      };
