## Class MediaView

- java.lang.Object
- - javafx.scene.Node
  - - javafx.scene.media.MediaView

- All Implemented Interfaces:
    `Styleable`, `EventTarget`

      public class MediaView
      extends Node

  A `Node` that provides a view of `Media` being played by a `MediaPlayer`.

  The following code snippet provides a simple example of an `Application.start()` method which displays a video:

       public void start(Stage stage) {
           // Create and set the Scene.
           Scene scene = new Scene(new Group(), 540, 209);
           stage.setScene(scene);

           // Name and display the Stage.
           stage.setTitle("Hello Media");
           stage.show();

           // Create the media source.
           String source = getParameters().getRaw().get(0);
           Media media = new Media(source);

           // Create the player and set to play automatically.
           MediaPlayer mediaPlayer = new MediaPlayer(media);
           mediaPlayer.setAutoPlay(true);

           // Create the view and add it to the Scene.
           MediaView mediaView = new MediaView(mediaPlayer);
           ((Group) scene.getRoot()).getChildren().add(mediaView);
       }

  The foregoing code will display the video as:
