How to: Play Media using a VideoDrawing
To play an audio or video file, you use a VideoDrawing and a MediaPlayer. There are two ways to load and play media. The first is to use a MediaPlayer and a VideoDrawing by themselves, and the second way is to create your own MediaTimeline to use with the MediaPlayer and VideoDrawing.

When distributing media with your application, you cannot use a media file as a project resource, like you would an image. In your project file, you must instead set the media type to |
Example
The following example uses a VideoDrawing and a MediaPlayer to play a video file once.
//
// Create a VideoDrawing.
//
MediaPlayer player = new MediaPlayer();
player.Open(new Uri(@"sampleMedia\xbox.wmv", UriKind.Relative));
VideoDrawing aVideoDrawing = new VideoDrawing();
aVideoDrawing.Rect = new Rect(0, 0, 100, 100);
aVideoDrawing.Player = player;
// Play the video once.
player.Play();
To gain additional timing control over the media, use a MediaTimeline with the MediaPlayer and VideoDrawing objects. The MediaTimeline enables you to specify whether the video should repeat.
The following example uses a MediaTimeline with the MediaPlayer and VideoDrawing objects to play a video repeatedly.
//
// Create a VideoDrawing that repeats.
//
// Create a MediaTimeline.
MediaTimeline mTimeline =
new MediaTimeline(new Uri(@"sampleMedia\xbox.wmv", UriKind.Relative));
// Set the timeline to repeat.
mTimeline.RepeatBehavior = RepeatBehavior.Forever;
// Create a clock from the MediaTimeline.
MediaClock mClock = mTimeline.CreateClock();
MediaPlayer repeatingVideoDrawingPlayer = new MediaPlayer();
repeatingVideoDrawingPlayer.Clock = mClock;
VideoDrawing repeatingVideoDrawing = new VideoDrawing();
repeatingVideoDrawing.Rect = new Rect(150, 0, 100, 100);
repeatingVideoDrawing.Player = repeatingVideoDrawingPlayer;
Note that, when you use a MediaTimeline, you use the interactive ClockController returned from the Controller property of the MediaClock to control media playback instead of the interactive methods of MediaPlayer.
