Unable to use <audio> and <video> tag in webview

Qjay

Hey all i have a very simple html file which i want to be displayed in webview .

the html file is as follows

<!doctype html>
<head>
	<title>Live audio </title>
</head>

<body>
        <audio controls preload="none">
<source src="http://dl.jatt.link/cdn8.jatt.link/057e667d427bd8fd751b66d2e7376183/wsezv/Main Tera Tu Meri-(Mr-Jatt.com).mp3" type="audio/mpeg">
Your browser does not support the audio element.
</audio>

</body>
</html>

the html file works fine when i load it in chrome or firefox . But when i load it in webview in my application it doesn't play it . Any idea why ??

this is how i am loading the file :

import QtQuick 2.0
import QtMultimedia 5.5
import QtWebView 1.1


Item{

    WebView {
           id: webView
           anchors.fill: parent
           url: "qrc:/documents/live_audio.html"
       }

}
