video player for AIR to play local files

Hi All,

I am developing an AIR application which can <b>play videos from local directory</b> as well as from server or Youtube. I am using JW Flash player for that.
I am able to play videos from server or Youtube, but when I give the path(relative to HTML page containing player). It gives an error: "Video not found: video.flv"
where video.flv is the video file that I am trying to play. And the video & HTML page are in the same directory.

<b>Please help me out in playing videos from local directory.</b>

Code Snippet is as follows:
<script type="text/javascript" src="swfobject.js"></script>
<script type='text/javascript' src='/embed/swfobject.js'></script>

<div id='preview'>This div will be replaced</div>

<script type='text/javascript'>
var s1 = new SWFObject('player.swf','ply','320','200','9','#ffffff');
s1.addParam('allowfullscreen','true');
s1.addParam('allowscriptaccess','always');
s1.addParam('wmode','opaque');
s1.addParam('flashvars','file=video.flv');
s1.write('preview');
</script>
