How to: Paint an Area with a Video
This example shows how to paint an area with media. One way to paint an area with media is to use a xref:System.Windows.Controls.MediaElement together with a xref:System.Windows.Media.VisualBrush. Use the xref:System.Windows.Controls.MediaElement to load and play the media, and then use it to set the xref:System.Windows.Media.VisualBrush.Visual%2A property of the xref:System.Windows.Media.VisualBrush. You can then use the xref:System.Windows.Media.VisualBrush to paint an area with the loaded media.
Use a MediaElement with a VisualBrush
The following example uses a xref:System.Windows.Controls.MediaElement and a xref:System.Windows.Media.VisualBrush to paint the xref:System.Windows.Controls.TextBlock.Foreground%2A of a xref:System.Windows.Controls.TextBlock control with video. This example sets the xref:System.Windows.Controls.MediaElement.IsMuted%2A property of the xref:System.Windows.Controls.MediaElement to true so that it produces no sound.

Use the VisualBrush with the loaded media
Because xref:System.Windows.Media.VisualBrush inherits from the xref:System.Windows.Media.TileBrush class, it provides several tiling modes. By setting the xref:System.Windows.Media.TileBrush.TileMode%2A property of a xref:System.Windows.Media.VisualBrush to xref:System.Windows.Media.TileMode.Tile and by setting its xref:System.Windows.Media.TileBrush.Viewport%2A property to a value smaller than the area that you are painting, you can create a tiled pattern.
The following example is identical to the previous example, except that the xref:System.Windows.Media.VisualBrush generates a pattern from the video.
