Automatically, the code, mentioned below will be generated in XAML code view, after we are finished in the design view.

  1. <Page x:Class="UWPSimpleAdaMedStream.MainPage" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:local="using:UWPSimpleAdaMedStream" xmlns:d="http://schemas.microsoft.com/expression/blend/2008" xmlns:mc="http://schemas.openxmlformats.org/markup-compatibility/2006" mc:Ignorable="d">  
  2.     <Grid Background="{ThemeResource ApplicationPageBackgroundThemeBrush}">  
  3.         <TextBlock x:Name="tblTitle" HorizontalAlignment="Left" Margin="206,10,0,0" TextWrapping="Wrap" Text="Simple Adaptive Streaming Demo" VerticalAlignment="Top" FontWeight="Bold" />  
  4.         <MediaPlayerElement x:Name="MPEAdaptive" HorizontalAlignment="Stretch" AreTransportControlsEnabled="True" />  
  5.     </Grid>  
  6. </Page>  
Step 4

Add the namespace, mentioned below in Mainpage.xaml.cs for media core, using Windows.Media.Core.

  1. System.Uri mfestUri = new Uri("http://amssamples.streaming.mediaservices.windows.net/91492735-c523-432b-ba01-faba6c2206a2/AzureMediaServicesPromo.ism/manifest(format=m3u8-aapl)");  
  2. MPEAdaptive.Source = MediaSource.CreateFromUri(mfestUri);  
  3. MPEAdaptive.MediaPlayer.Play();
