Remarks

The Media playback section of the documentation contains how-to articles that provide detailed guidance for adding media playback features to your app. The following table lists some of the available articles.

Topic	Description
Play audio and video with MediaPlayer	Shows you how to take advantage of the new features and improvements to the media playback system for UWP apps.

IsLoopingEnabled	Gets or sets a Boolean value indicating if the media will playback in a repeating loop.
IsMuted	Gets or sets a Boolean value indicating if the audio is muted.
IsProtected	Gets a Boolean value indicating if the content is protected by a digital rights management system. Note MediaPlayer.IsProtected may be altered or unavailable after Windows 10, version 1607. Instead, use the MediaPlayer.PlaybackSession property to get a MediaPlaybackSession object and then use the IsProtected property.
IsVideoFrameServerEnabled	Gets a value indicating whether video frame server mode is enabled for the MediaPlayer instance.
NaturalDuration	Get the actual duration of the media without applying the PlaybackRate. Note MediaPlayer.NaturalDuration may be altered or unavailable after Windows 10, version 1607. Instead, use the MediaPlayer.PlaybackSession property to get a MediaPlaybackSession object and then use the MediaPlaybackSession.NaturalDuration property.
PlaybackMediaMarkers	Gets the collection of timeline markers for the media. Note MediaPlayer.PlaybackMediaMarkers may be altered or unavailable after Windows 10, version 1607. Instead, use MediaPlaybackItem.TimedMetadataTracks to manage data or text cues. For more information, see Media playback with MediaSource.
