Opening And Playing A Video File In Windows 10

Here we are using a FilePicker to open a file and a MediaElement to play the same.

Step 1: Open a blank app and add a MediaElement and a TextBlock either from the toolbox or by copying the following XAML code into your grid:

<TextBlock Text="Video" FontSize="20"></TextBlock>
<StackPanel Margin="0,40,0,0">
    <Button Name="open" Content="Open" Margin="15,0,0,0" Width="120" Height="30" Click="open_Click"></Button>
    <MediaElement x:Name="myMedia" AutoPlay="False" Margin="5" HorizontalAlignment="Stretch" AreTransportControlsEnabled="True"></MediaElement>
</StackPanel>

  

Step 2: Add the following namespaces to your project, which is needed in further C# code.

using Windows.Media.Core;
using Windows.Storage;
using Windows.Storage.Pickers;

Step 3: Copy and paste the following code to the cs pag, which will be called on button click event.

private async void open_Click(object sender, RoutedEventArgs e)
{
    FileOpenPicker openPicker = new FileOpenPicker();
    openPicker.ViewMode = PickerViewMode.Thumbnail;
    openPicker.SuggestedStartLocation = PickerLocationId.VideosLibrary;
    openPicker.FileTypeFilter.Add(".mp4");
    openPicker.FileTypeFilter.Add(".mkv");
    openPicker.FileTypeFilter.Add(".avi");

    StorageFile file = await openPicker.PickSingleFileAsync();

    myMedia.AutoPlay = true;
    myMedia.SetPlaybackSource(MediaSource.CreateFromStorageFile(file));
    myMedia.Play();
}

Step 4: Run your application and test yourself.
