Hi  
I want to play just a video, it work great in processing IDE with the librairy processing.video.\*;  
But with Eclipse i can’t play anything, it seems that there is a problem with gstreamer.  
I have this error.  
Can you help me, i’m stuck.

```auto

```

With this code :

```Processing
package core; 

import processing.core.*;
import processing.video.*;

import java.io.File;

public class Loop extends PApplet {

    Movie movie;

    public void settings() {
        size(560, 406); // Définit la taille de la fenêtre
    }

    public void setup() {
        background(0);

        // Vérifier si le fichier vidéo est bien accessible
        String videoPath = sketchPath("launch2.mp4");
        File videoFile = new File(videoPath);
        if (!videoFile.exists()) {
            System.err.println("Erreur : La vidéo 'launch2.mp4' n'a pas été trouvée dans le dossier 'data/'.");
            exit();
        }

        // Charger et jouer la vidéo en boucle
        movie = new Movie(this, videoPath);
        movie.loop();
    }

    public void movieEvent(Movie m) {
        m.read(); // Lire les nouvelles frames de la vidéo
    }

    public void draw() {
        if (movie.width > 0 && movie.height > 0) {
            image(movie, 0, 0, width, height);
        } else {
            background(0); // Écran noir en attendant la vidéo
        }
    }

    public static void main(String[] passedArgs) {
        PApplet.main(core.Loop.class.getName()); // Appelle la classe Loop avec son package
    }
}

```
