Phonegap Android Webview Video plays only audio

I've started to play around with phonegab today. When I was trying to capture video its working fine. Now I wanna show the captured video in the webview. so I was trying as below.

var captureSuccess = function(mediaFiles) {
     var i, path, len;
     for (i = 0, len = mediaFiles.length; i < len; i += 1) {
         path = mediaFiles[i].fullPath;
         videoString = "<video width='320' height='240' controls='controls'><source src="+path+" type='video/mp4' /> <source src="+path+" type='video/ogg' />   <source src="+path+" type='video/webm' />Your browser does not support the video tag.</video>";
         $('#myVideo').html(videoString);
     }
 
 
 };
 
 // capture error callback
 var captureError = function(error) {
     navigator.notification.alert('Error code: ' + error.code, null, 'Capture Error');
 };
 
 // start video capture
 function takeVideo(){
     navigator.device.capture.captureVideo(captureSuccess, captureError, {limit:1});
 }
 

but in the UI I see the player being appended but it plays only the audio not the video.. wot could be the problem.??

Any help appreciated and thanks for your time in advance.
