JavaFX provides comprehensive media playback capabilities through its Media, MediaPlayer, and MediaView classes. This guide covers everything from basic audio/video playback to advanced features and custom media players.

Basic Media Playback

1. Simple Audio Player

SimpleAudioPlayer.java:

import javafx.application.Application; import javafx.scene.Scene; import javafx.scene.control.Button; import javafx.scene.control.Label; import javafx.scene.control.Slider; import javafx.scene.layout.VBox; import javafx.stage.Stage; import javafx.scene.media.Media; import javafx.scene.media.MediaPlayer; import javafx.util.Duration; public class SimpleAudioPlayer extends Application { private MediaPlayer mediaPlayer; private Label statusLabel; private Slider volumeSlider; private Slider progressSlider; @Override public void start(Stage primaryStage) { // Create UI components Button playButton = new Button("Play"); Button pauseButton = new Button("Pause"); Button stopButton = new Button("Stop"); Button loadButton = new Button("Load Audio"); statusLabel = new Label("No media loaded"); volumeSlider = new Slider(0, 100, 50); progressSlider = new Slider(0, 100, 0); // Layout VBox root = new VBox(10); root.setStyle("-fx-padding: 20; -fx-alignment: center;"); root.getChildren().addAll( statusLabel, playButton, pauseButton, stopButton, loadButton, new Label("Volume:"), volumeSlider, new Label("Progress:"), progressSlider ); // Event handlers playButton.setOnAction(e -> playMedia()); pauseButton.setOnAction(e -> pauseMedia()); stopButton.setOnAction(e -> stopMedia()); loadButton.setOnAction(e -> loadMedia()); volumeSlider.valueProperty().addListener((obs, oldVal, newVal) -> setVolume(newVal.doubleValue())); Scene scene = new Scene(root, 400, 300); primaryStage.setTitle("JavaFX Audio Player"); primaryStage.setScene(scene); primaryStage.show(); } private void loadMedia() { try { // Replace with your audio file path String audioFile = getClass().getResource("/audio/sample.mp3").toString(); Media media = new Media(audioFile); if (mediaPlayer != null) { mediaPlayer.dispose(); } mediaPlayer = new MediaPlayer(media); setupMediaPlayer(); statusLabel.setText("Media loaded: " + getFileName(audioFile)); } catch (Exception e) { statusLabel.setText("Error loading media: " + e.getMessage()); } } private void setupMediaPlayer() { mediaPlayer.setOnReady(() -> { statusLabel.setText("Media ready to play"); progressSlider.setMax(mediaPlayer.getTotalDuration().toSeconds()); }); mediaPlayer.currentTimeProperty().addListener((obs, oldTime, newTime) -> { if (!progressSlider.isValueChanging()) { progressSlider.setValue(newTime.toSeconds()); } }); progressSlider.valueProperty().addListener((obs, oldVal, newVal) -> { if (progressSlider.isValueChanging()) { mediaPlayer.seek(Duration.seconds(newVal.doubleValue())); } }); mediaPlayer.setOnEndOfMedia(() -> { statusLabel.setText("Playback finished"); mediaPlayer.stop(); }); mediaPlayer.setVolume(volumeSlider.getValue() / 100.0); } private void playMedia() { if (mediaPlayer != null) { mediaPlayer.play(); statusLabel.setText("Playing..."); } } private void pauseMedia() { if (mediaPlayer != null) { mediaPlayer.pause(); statusLabel.setText("Paused"); } } private void stopMedia() { if (mediaPlayer != null) { mediaPlayer.stop(); statusLabel.setText("Stopped"); } } private void setVolume(double volume) { if (mediaPlayer != null) { mediaPlayer.setVolume(volume / 100.0); } } private String getFileName(String path) { return path.substring(path.lastIndexOf("/") + 1); } public static void main(String[] args) { launch(args); } }

2. Basic Video Player
