String sURL = "http://yourDomain/YourFile.wmv";
    
    System.Net.WebRequest request = System.Net.WebRequest.Create(sURL);
    System.Net.WebResponse response = request.GetResponse();
    
    String outputBaseFilename = "d://test.gif";
    try
    {
        //Create the reader
        WMReader reader = new WMReader(response.GetResponseStream());
        Int32 index = reader.FrameCount/2;
       
        IFrame frame = reader.LoadFrame(index);
        //Save the frame using GetThumbnail()
        Aurigma.GraphicsMill.Bitmap image = new Aurigma.GraphicsMill.Bitmap();
        frame.GetThumbnail(image, 160, 120);
        image.Save(outputBaseFilename + @"1.gif");
        image.Dispose();
        reader.Dispose();
