Video Brush in WPF

Video Brush

A video brush is a brush similar to any other brush. Instead of painting an area with a color, a video brush paints an area with a video. The video contents are provided by a MediaElement. We can use a visualBrush to play a media by setting a MediaElement as its Visual attribute.

The following code snippet creates a MediaElement. The Source property of the MediaElement is the name of the video file.

The code snippet in Listing 27 creates a VisualBrush and sets its Visual attribute to a MediaElement.

Code

<VisualBrush >

Code

      <VisualBrush.Visual >

Java

<MediaElement Source="Lake.wmv"                              Name="McMediaElement" Width="450" Height="250" LoadedBehavior="Manual" UnloadedBehavior="Stop" Stretch="Fill />

Code

      </VisualBrush.Visual >

Code

</VisualBrush >

Listing 27

The code snippet in Listing 28 creates a MediaElement and sets it as the Visual property of a VisualBrush.

Code

MediaElement McMediaElement = new MediaElement();

Code

McMediaElement.Source = new Uri("Lake.wmv", UriKind.Relative);

Code

McMediaElement.IsMuted = false;

Code

VisualBrush videoBrush = new VisualBrush ();

Code

videoBrush.Visual = McMediaElement;
