I have a problem with the JavaFX Media module on Linux (Ubuntu Budgie). Every time I try to create javafx.scene.media.MediaPlayer
, I have this happening:

Exception running application Test.MediaTest
Here is the code:
import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.layout.Pane;
import javafx.scene.media.Media;
import javafx.scene.media.MediaPlayer;
import javafx.scene.media.MediaView;
import javafx.stage.Stage;
public class MediaTest extends Application{
private static final String MEDIA_URL = "file:///home/michael/eclipse-workspace/JFXTest/VideoExample.mp4";
@Override
public void start(Stage stage) throws Exception {
Pane pane = new Pane();
pane.setPrefSize(640, 480);
Media media = new Media(MEDIA_URL);
MediaPlayer mediaPlayer = new MediaPlayer(media);
mediaPlayer.setOnReady(new Runnable(){
@Override
public void run() {
System.out.println(media.getWidth() +" x "+ media.getHeight() +" : "+ media.getDuration());
mediaPlayer.play();
}
});
Scene scene = new Scene(pane, 640, 480);
MediaView mediaView = new MediaView(mediaPlayer);
pane.getChildren().add(mediaView);
stage.setTitle("Why it doesn't work?");
stage.setScene(scene);
stage.show();
}
public static void main(String[] args) {
launch();
}
}
I know there are some questions on Stackoverflow regarding this issue, but none of them (the ones I found and checked) helps me.
I tried:
new Media(new File(MEDIA_URL).toURI().toString())
instead of new Media(MEDIA_URL)
http://download.oracle.com/otndocs/products/javafx/oow2010-2.flv
instead of local videojmods
libavcodec58
and libavformat58
(as noted in JavaFX 2 Certified System ConfigurationsGLIB
2.31 (Ubuntu GLIBC 2.31-0ubuntu9.2)I have no ideas what else I could be missing or done wrong. I would be grateful for any help!
The problem resolved itself (Hmm?).
jmod
s instead of jar
s and recompiled => didn't work;
