Мой код использует JavaFX для воспроизведения видео и возвращает исключение java.lang.reflect.InvocationTargetException. Для этого я использую MediaPlayer и MediaView. Я не уверен, почему он выбрасывает это исключение, поскольку это практически тот же код, который я видел на javatpoint для добавления MediaPLayer.
package application;
import java.io.File;
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene; `enter code here`
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;
import javafx.stage.Stage;
public class Main extends Application
{
@Override
public void start(Stage primaryStage) throws Exception {
String path = "C:\\Users\\fbstudent\\Downloads\\Urgent Message.mp4";
Media media = new Media(new File(path).toURI().toString());
MediaPlayer mediaPlayer = new MediaPlayer(media);
MediaView mediaView = new MediaView(mediaPlayer);
mediaPlayer.setAutoPlay(true);
Group root = new Group();
root.getChildren().add(mediaView);
Scene scene = new Scene(root,500,400);
primaryStage.setScene(scene);
primaryStage.setTitle("Playing video");
primaryStage.show();
}
public static void main(String[] args) {
launch(args);
}
}
Он возвращает следующее сообщение об ошибке в консоли. Любая помощь в решении этой проблемы будет принята с благодарностью!
