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.
