Trying to change video source file using createObjectDataURL. It is working fine with Firefox but not working in Chrome (version 12.0.742.122 m). code is not throwing any error but returns undefined for createObjectDataURL. I tried all the possibilities but it always returns undefined.

<!DOCTYPE html>
<html>
<head>
<title>Check CreateObjectURL</title>
</head>
<script type="text/javascript" language="javascript">

window.URL = window.URL || window.webkitURL;

function ChangeProperty()
{
        var v = document.getElementById("myvideo");
        var file = document.getElementById("fileControl").files[0];
        v.setAttribute("src",window.URL.createObjectURL(file));
}
</script>
<body>
<div >
    <video id="myvideo" src="movie.ogg" controls ></video>
    <input type="file" id="fileControl" /> 
    <button id="btnprops" onClick="ChangeProperty()" >update</button>
</div>
</body>
</html>

Please help me. It has already taken lot of time. Thanks in Advance.

This seems to be a bug in Chromium, though the status of the bug is unclear to me: http://code.google.com/p/chromium/issues/detail?id=91136

Crossposting my comment there:

I can confirm this issue on Windows Chrome 17.0.932.0 dev-m. An easy way to confirm [the bug] is this page: http://html5-demos.appspot.com/static/a.download.html. It works when used online. After saving to disk, the download fails.

Edit: Just found this similar bug report (FileReader API not working for local content): http://code.google.com/p/chromium/issues/detail?id=60889 This is marked won't fix for a reason that appears applicable to the bug discussed here.
