Java SE (Java Platform, Standard Edition)

I've been testing Canvas performance on a very fast machine (quad core Xeon) with a one of the latest NVidia graphics boards, but I'm unable to render full screen 1920x1080 video with this setup using the Canvas.

Is this simply too much to hope for or am I missing some obvious performance improvements?

Here's the code I used:

import java.nio.ByteBuffer;

import javafx.application.Application;
import javafx.scene.Scene;
import javafx.scene.canvas.Canvas;
import javafx.scene.image.PixelFormat;
import javafx.scene.image.PixelWriter;
import javafx.scene.image.WritablePixelFormat;
import javafx.scene.layout.BorderPane;
import javafx.stage.Stage;
import uk.co.caprica.vlcj.component.DirectMediaPlayerComponent;

import com.sun.jna.Memory;
import com.sun.jna.NativeLibrary;

public class VLCDirectTest extends Application {

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

  private DirectMediaPlayerComponent mp;

  @Override
  public void start(Stage primaryStage) throws Exception {
    NativeLibrary.addSearchPath("libvlc", "c:/program files (x86)/videolan/vlc");

    BorderPane borderPane = new BorderPane();
    final Canvas canvas = new Canvas(1920, 1080);
    borderPane.setCenter(canvas);
    System.out.println(">>> " + canvas.getGraphicsContext2D().getPixelWriter().getPixelFormat());
    Scene scene = new Scene(borderPane);
    final PixelWriter pixelWriter = canvas.getGraphicsContext2D().getPixelWriter();
    final WritablePixelFormat<ByteBuffer> byteBgraInstance = PixelFormat.getByteBgraInstance();

    mp = new DirectMediaPlayerComponent("RV32", 1920, 1080, 1920*4) {
      @Override
      public void display(Memory nativeBuffer) {
        ByteBuffer byteBuffer = nativeBuffer.getByteBuffer(0, nativeBuffer.size());
        pixelWriter.setPixels(0, 0, 1920, 1080, byteBgraInstance, byteBuffer, 1920*4);
      }
    };

    mp.getMediaPlayer().playMedia("L:\\test-movies\\2012.mkv");

    primaryStage.setScene(scene);
    primaryStage.show();
  }
}

It works, but it hickups and distorts a lot when it hickups. Lowering the resolution to say 1600x900 makes it almost smooth. Lowering it further gets the expected 24 frames per second.
