Andropid Media Library issue

Hi Friends,

Am trying to get Android video recorder Thumbnail image. "thumbnailimageAttime" methos is not supporting for Android so i decided to using "Android Media Library Module" with passing my video url via trying to get Blob object for videothumbnailimage. but i can't get blob object from my url. Please check my below code if i did any mistakenly correct and post here. if you have any other idea about this please post me immideatly for urgent development purpose.

This is my code:-

    ~~~ 

    var videourl = "http://www.broken-links.com/tests/media/BBB_480_HB.mp4";
    alert(JSON.stringify(videourl));

    var list = media.getItems(media.MEDIA_TYPE_VIDEO);

    var thumbBlob = media.getImageAtTime(videourl,500);
    alert("thumb: "+thumbBlob); //can't get Blob object 

    ~~~

This is Module Example code:-

    ~~~ 
    var masterWin = Ti.UI.createWindow({
    navBarHidden : false,
    backgroundColor : "#fff"
    });
    masterWin.open();

    * MEDIA_TYPE_ALL - returns list of all media items
     *
     * To get only images and videos
    * media.getItems(media.MEDIA_TYPE_IMAGE, media.MEDIA_TYPE_VIDEO);
    */
    var list = media.getItems(media.MEDIA_TYPE_ALL);
    Ti.API.info(JSON.stringify(list));
    /*
