Bonsoir tout le monde. Pour m'exercer j'essaie de faire un simple lecteur vidéo mais je n'arrive pas à exécuter mon code pourtant il y a aucun problème lors de la compilation. Je pense qui c'est lié à l'IDE (Intellij IDEA) car je n'ai aucun problème avec Netbeans.

Voilà le code:

package sample;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.StackPane;
import javafx.scene.layout.VBox;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;
import javafx.stage.Stage;

import java.net.URL;

public class Main extends Application {

    @Override
    public void start(Stage primaryStage) {

        StackPane root = new StackPane();

        VBox box = new VBox();

        URL maVideo = getClass().getResource("video.mp4");
        Media media = new Media(maVideo.toString()); //Erreur ici apparemment

        MediaPlayer mediaPlayer = new MediaPlayer(media);
        mediaPlayer.setAutoPlay(true);

        MediaView mediaView = new MediaView(mediaPlayer);

        box.getChildren().add(mediaView);
        root.getChildren().add(box);

        Scene scene = new Scene(root, 800, 600);

        primaryStage.setTitle("Hello World!");
        primaryStage.setScene(scene);
        primaryStage.show();
    }


    public static void main(String[] args) {
        launch(args);
    }
}

Voici le message d'erreur:

il manque peut-être un import javafx.graphics; ?
