Windows requirements

Device family	Windows 10 (introduced in 10.0.10240.0)
API contract	Windows.Foundation.UniversalApiContract (introduced in v1.0)

Remarks

Using one of the factory methods, you can create an instance of MediaSource from many different media source representations, including:

After getting a MediaSource instance, create a new MediaPlaybackItem wrapping the media source and pass the MediaPlaybackItem to one of the media playback objects, such as MediaPlayer or MediaElement.

For how-to guidance for using MediaSource to play back media, see Media items, playlists, and tracks.
