Solved: how to loop javafx media player

how to loop media player In the world of modern media, the ability to loop a media player has become a highly sought-after feature. This is especially true for those moments when we just cannot get enough of a song, video or any piece of media that we truly enjoy. Looping the media player ensures that the content continually plays, allowing users to enjoy it without having to restart it manually. This article addresses how to loop a media player using Java, a popular programming language, along with an in-depth, step-by-step guide on coding the solution. Let’s now dive into looping the media player and explore the libraries and functions involved in this process.

Using Java Media Framework (JMF) for looping

Java Media Framework (JMF) is a powerful library that enables the development of multimedia applications in Java. It provides support for audio, video, and other time-based media, making it the ideal choice for implementing looping functionality in a media player. In this section, we will delve into the JMF library and discuss how to loop media content using a step-by-step explanation of the code.


public class MediaPlayerLooper {
    public static void main(String[] args) {
        try {
            // Create a media locator from a file URL
            MediaLocator mediaLocator = new MediaLocator(new URL("file:///path/to/media/file"));

            // Create a Player from the media locator
            Player player = Manager.createPlayer(mediaLocator);

            // Add a controller listener to the player
            player.addControllerListener(new ControllerAdapter() {
                public void endOfMedia(EndOfMediaEvent e) {
                    // Set media time to zero and restart the player
                    player.setMediaTime(new Time(0));

            // Start playing the media
        } catch (Exception e) {

The code snippet above demonstrates the following steps:

1. Import JMF and other necessary libraries
2. Create a MediaPlayerLooper class
3. Utilize the MediaLocator to create a media object
4. Create a Player using the Manager class with the specified media object
5. Add a ControllerListener to the player to monitor its state changes
6. Handle the `endOfMedia` event, which occurs when the media finishes playing, by resetting the media time to zero and restarting the player
7. Start playing the media

Looping with MediaPlayer in JavaFX

JavaFX is another popular library for creating multimedia applications in Java. Its MediaPlayer class offers a built-in looping functionality, making it even simpler to loop media files. In this section, we’ll look into using JavaFX’s MediaPlayer to loop media content.

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.stage.Stage;

public class JavaFXMediaPlayerLooper extends Application {
    public void start(Stage primaryStage) {
        File mediaFile = new File("path/to/media/file");
        Media media = new Media(mediaFile.toURI().toString());
        MediaPlayer mediaPlayer = new MediaPlayer(media);
        MediaView mediaView = new MediaView(mediaPlayer);

        StackPane root = new StackPane();
        Scene scene = new Scene(root, 800, 600);
        primaryStage.setTitle("Media Player Looper");

    public static void main(String[] args) {

The JavaFX code example above introduces the following steps:

1. Import JavaFX libraries
2. Create a JavaFXMediaPlayerLooper class extending from Application
3. Load the media file using the Media class
4. Create a MediaPlayer object with the loaded media
5. Set the cycleCount attribute of the MediaPlayer to INDEFINITE for looping
6. Create a MediaView object and add it to the scene graph
7. Initialize the user interface components, such as the stage and scene
8. Start playing the media

In summary, looping a media player in Java can be achieved using libraries like JMF and JavaFX. By understanding the functions and classes provided by these libraries, developers can create efficient and engaging applications that cater to users’ media looping needs.
