NameDescription
System_CAPS_pubmethodApplyAnimationClock(DependencyProperty, AnimationClock)

Clears the local value of a read-only property. The property to be cleared is specified by a DependencyPropertyKey. (Inherited from DependencyObject.)

System_CAPS_pubmethodClone()

Creates a modifiable clone of this Animatable, making deep copies of this object's values. When copying this object's dependency properties, this method copies resource references and data bindings (but they might no longer resolve) but not animations or their current values. (Inherited from Animatable.)

System_CAPS_pubmethodCloneCurrentValue()

Creates a modifiable clone (deep copy) of the Freezable using its current values.(Inherited from Freezable.)

System_CAPS_protmethodCloneCurrentValueCore(Freezable)

Makes this instance a modifiable deep copy of the specified MediaPlayer using current property values. Resource references, data bindings, and animations are not copied, but their current values are.(Overrides Freezable.CloneCurrentValueCore(Freezable).)

System_CAPS_pubmethodClose()

Closes the underlying media.

System_CAPS_pubmethodCoerceValue(DependencyProperty)

Coerces the value of the specified dependency property. This is accomplished by invoking any CoerceValueCallback function specified in property metadata for the dependency property as it exists on the calling DependencyObject.(Inherited from DependencyObject.)

System_CAPS_protmethodCreateInstance()

Initializes a new instance of the Freezable class. (Inherited from Freezable.)

System_CAPS_protmethodCreateInstanceCore()

System_CAPS_pubmethodGetAnimationBaseValue(DependencyProperty)

Returns the non-animated value of the specified DependencyProperty.(Inherited from Animatable.)

System_CAPS_pubmethodGetAsFrozen()

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.
