|AlignmentY||Gets or sets the vertical alignment of content in the TileBrush base tile. (Inherited from TileBrush.)|
|Dispatcher||Gets the Dispatcher this object is associated with. (Inherited from DependencyObject.)|
|Opacity||Gets or sets the degree of opacity of a Brush. (Inherited from Brush.)|
|RelativeTransform||Gets or sets the transformation that is applied to the brush using relative coordinates. (Inherited from Brush.)|
|SourceName||Gets or sets the name of the MediaElement to use as the source of the VideoBrush.|
|Stretch||Gets or sets a value that specifies how the content of this TileBrush stretches to fit its tiles. (Inherited from TileBrush.)|
|Transform||Gets or sets the transformation that is applied to the brush. (Inherited from Brush.)|

|ClearValue||Clears the local value of a dependency property. (Inherited from DependencyObject.)|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before the Object is reclaimed by garbage collection. (Inherited from Object.)|
|GetAnimationBaseValue||Returns any base value established for a Silverlight dependency property, which would apply in cases where an animation is not active. (Inherited from DependencyObject.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|GetValue||Returns the current effective value of a dependency property from a DependencyObject. (Inherited from DependencyObject.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ReadLocalValue||Returns the local value of a dependency property, if a local value is set. (Inherited from DependencyObject.)|
|SetSource(CaptureSource)||Sets the source of the VideoBrush using a video capture source|
|SetSource(MediaElement)||Sets the source of the VideoBrush using a media file source from an intermediary MediaElement control.|

A detailed walkthrough of how to use a VideoBrush is documented in VideoBrush Overview.
A VideoBrush is a type of Brush object similar to a LinearGradientBrush or an ImageBrush. However, instead of painting an area with a solid color, a gradient, or an image, it paints an area with video content. This video content is provided by a MediaElement. Just like the other brush types, you can use a VideoBrush to paint the Fill of a shape such as a Rectangle or the geometry contents of a Path, the Background of a Canvas, or the Foreground of a TextBlock or Run.
To use a VideoBrush, you create a MediaElement, apply the VideoBrush to the object that you want to paint, and set the VideoBrush object's SourceName property to the name of the MediaElement that you created.
Silverlight 4 introduces an overload of SetSource(CaptureSource) that is used for webcam scenarios. For this scenario, you set the source video for a VideoBrush using a CaptureSource. For more information on obtaining a CaptureSource and webcam scenarios, see CaptureSource and VideoSink.
