Ugly Hack to generate a QR Code from the YouTube live RTMP server & key page

youtube.live-qr-url.js

// get the server URL
var server_url = $("[value^=rtmp]").value;

// get the current key
var stream_key = $(".stream-name-text").value;

// assemble the QR code, thanks http://stackoverflow.com/a/9447876
var div = $("#yt-masthead-content");
var qrIMG = 'https://chart.googleapis.com/chart?chl=' + server_url + '/' + stream_key + '&chld=M%7C0&cht=qr&chs=125x125';
var img = document.createElement('img');
img.src=qrIMG;
img.width=125;
img.height=125;
div.appendChild(img);
