MediaView (JavaFX 25)
Description: declaration: module: javafx.media, package: javafx.scene.media, class: MediaView

# 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:
