Error while playing video

Question

I know this is very easy stuff but I cannot make it work. I added video file (.wmv) to my project and tried to play it with a media Element. But I always have an error that is : MF_MEDIA_ENGINE_ERR_SRC_NOT_SUPPORTED : HRESULT - 0x80004005

Here is the code :

<Page
    x:Class="MyMobileApp.MainPage"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    xmlns:local="using:MyMobileApp"
    xmlns:d="http://schemas.microsoft.com/expression/blend/2008"
    xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006"
    mc:Ignorable="d"
    Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">
    <Grid>
        <MediaElement x:Name="MyMediaElement" Height="640" Width="400" Source="GOPR0179.wmv" MediaFailed="MediaElement_MediaFailed"/>
    </Grid>
</Page>

Can you please help me?

Here is the code behind :

private void MediaElement_MediaFailed(object sender, ExceptionRoutedEventArgs e)
    {
        System.Diagnostics.Debug.WriteLine(e.ErrorMessage);
    }
