[ This article is for Windows 8.x and Windows Phone 8.x developers writing Windows Runtime apps. If you’re developing for Windows 10, see the latest documentation ]

This section contains topics on playing audio and video in your Windows Runtime app using C++, C#, or Visual Basic.

It covers how to play audio and video using the MediaElement class, share or stream media with Play To, and use effects and custom media extensions.

The control to play audio and video media is MediaElement. This is defined in the Windows.UI.Xaml.Controls namespace. The majority of the API to playback media are in Windows.Media, Windows.Media.MediaProperties, Windows.Media.PlayTo, and Windows.Media.Transcoding.

For samples that use audio and video in a Windows Runtime app using C++, C#, or Visual Basic, see the XAML media playback sample and the other samples listed in the Samples section in the Related topics below.

To see many of features in action as part of a complete media-playback sample, see Media playback, start to finish.
