![]() | Changed | |
![]() | MediaEnded | Occurs when the media has finished playback. |

![]() | ScriptCommand | Occurs when a script command has been encountered within the media. |
Although you can declare an instance of this class in Extensible Application Markup Language (XAML), you cannot load and play its media without using code. To play media in XAML only, use a MediaElement. Also, if you declare an instance in XAML, the only practical use is to fill property element syntax for the Player property.
When distributing media with your application, you cannot use a media file as a project resource. In your project file, you must instead set the media type to Content and set CopyToOutputDirectory to PreserveNewest or Always.
MediaPlayer can be used in two different modes, depending on what is driving the player: independent mode or clock mode. In independent mode, the MediaPlayer is analogous to an image and the media opened through the Open method drives playback. In Clock mode, the MediaPlayer can be thought of as a target for an animation, and thus it will have corresponding Timeline and Clock entries in the Timing tree which controls playback. For more information on media modes, see the Multimedia Overview.
MediaPlayer is different from a MediaElement in that it is not a control that can be added directly to the user interface (UI) of an application. To display media loaded using MediaPlayer, a VideoDrawing or DrawingContext must be used.
