How to use MediaElement and play . wmv file (video file) in WPF application?

WPF applications can be used for playing videos by using MediaElement class. Various video files can be played in different sytem's windows shapes. I have used Ellipse.

To play video file. Video will be shown in Ellipse at runtime.
Create WPF application and add this code in MainWindow.xaml

<Window x:Class="exampleMediaElement.MainWindow"
        xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
        xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
        WindowStyle="None"          
        Background="Transparent"
        AllowsTransparency="True"
        MouseLeftButtonDown="Window_MouseLeftButtonDown"
        Title="MainWindow" 
        Height="450" Width="650">
<Grid>
  <TextBlock Text="Welcome" FontSize="20"
                   FontWeight="ExtraBold"
                   HorizontalAlignment="Center"
                   VerticalAlignment="Center"/>
<Ellipse>
  <Ellipse.Fill>
     <VisualBrush>
           <VisualBrush.Visual>
               <MediaElement Source="videofilepath\filename.wmv"
                LoadedBehavior="Play"/>
            </VisualBrush.Visual>
                </VisualBrush>
  </Ellipse.Fill>
</Ellipse>
</Grid>
</Window>
