Impossible d'encoder la vidéo avec Xuggler

Question

Je suis en train de créer l'application simple avec Xuggler, qui doit séquence encode des images en vidéo. J'ai installé xuggler, comme décrit dans le site officiel. Voici exemple de code (que j'ai effectivement trouvé sur le site de Xuggler)

import java.awt.Color;
import java.awt.Graphics2D;
import java.awt.image.BufferedImage;

import org.slf4j.Logger;
import org.slf4j.LoggerFactory;

import com.xuggle.mediatool.IMediaViewer;
import com.xuggle.mediatool.IMediaWriter;
import com.xuggle.mediatool.ToolFactory;
import com.xuggle.xuggler.ICodec;

import static com.xuggle.xuggler.Global.DEFAULT_TIME_UNIT;
import static java.util.concurrent.TimeUnit.SECONDS;
import static java.util.concurrent.TimeUnit.MILLISECONDS;


public class Test {

    private static final Logger log = LoggerFactory.getLogger(Test.class);
    {
        log.trace("<init>");
    }

    public static void main(String[] args) {

        final long duration = DEFAULT_TIME_UNIT.convert( 3, SECONDS );

        final int videoStreamIndex = 0;
        final int videoStreamId = 0;
        final long frameRate = DEFAULT_TIME_UNIT.convert(15, MILLISECONDS);
        final int width = 320;
        final int height = 200;

        long nextFrameTime = 0;

        final IMediaWriter writer = ToolFactory.makeWriter("/out.mov");

        writer.addVideoStream(videoStreamIndex, videoStreamId, 
                      width, height);

        while ( nextFrameTime < duration )
            {
                BufferedImage frame = new BufferedImage( 320, 200, BufferedImage.TYPE_INT_RGB );
                Graphics2D gr = (Graphics2D) frame.getGraphics();
                gr.setColor(Color.RED);
                gr.drawLine(0, 0, 200, 200);
                writer.encodeVideo(videoStreamIndex, frame, nextFrameTime, 
                       DEFAULT_TIME_UNIT);
                nextFrameTime += frameRate;
            }

        writer.close();

    }

}

Après le lancement, j'ai exception:

Exception in thread "main" java.lang.UnsupportedOperationException: No converter "null" found.
    at com.xuggle.xuggler.video.ConverterFactory.createConverter(ConverterFactory.java:313)
    at com.xuggle.mediatool.MediaWriter.convertToPicture(MediaWriter.java:967)
    at com.xuggle.mediatool.MediaWriter.encodeVideo(MediaWriter.java:812)
    at Test.main(Test.java:48)

Pouvez-vous me conseiller quelque chose pour résoudre ce problème? Merci

Xuggler is complaining that it cannot find a converter for the BufferedImage.

Create the BufferedImage with BufferedImage.TYPE_3BYTE_BGR instead of BufferedImage.TYPE_INT_RGB
