Exception running application javafxapplication4.JavaFXApplication4

But my code compile in net bean it work

public class JavaFXApplication4 extends Application {

private static String pathopencv;

@Override
public void start(Stage primaryStage) {
    System.setProperty("java.net.useSystemProxies", "true");
    ImageView live = new ImageView();
    threadCV1 cv = new threadCV1();
    //
    cv.opencvmera(pathopencv, live, 800, 600);

    StackPane root = new StackPane();
    root.getChildren().add(live);

    Scene scene = new Scene(root, 800, 600);

    primaryStage.setTitle("live Stream Link " + pathopencv);
    primaryStage.setScene(scene);
    primaryStage.show();

}

/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
   System.loadLibrary(Core.NATIVE_LIBRARY_NAME);
    System.load("C:\\opencv\\build\\bin\\opencv_ffmpeg401_64.dll");
    pathopencv = "rtsp://admin:[email protected]:554/Streaming/Channels/101/";
    System.out.println("pathopencv +++"+pathopencv);
    launch(args);
}}

And i set native library project properties>>run>>VM options is -Djava.library.path="C:\opencv\build\java\x64"
