JavaFX periodically playing FLV video in JFXPanel

I am developing in Java SE 7. I am using JavaFX in Swing application for periodically playing flv video in JFXPanel.

public class MyVideoPlayer {

public MyVideoPlayer(final JLayeredPane myPanel, final String mediaURI) {
    SwingUtilities.invokeLater(new Runnable() {
        @Override
        public void run() {
            initAndShowGUI(ballMixerPnl, mediaURI);
        }
    });
}

private static void initAndShowGUI(JLayeredPane myPanel, final String mediaURI) {
    // This method is invoked on the EDT thread
    final JFXPanel fxPanel = new JFXPanel();
    myPanel.add(fxPanel);

    Platform.runLater(new Runnable() {
        @Override
        public void run() {
            initAndPlayVideo(fxPanel, mediaURI);
        }
    });

}

private static void initAndPlayVideo(JFXPanel fxPanel, String mediaURI) {
    Group root = new Group();
    Scene scene = new Scene(root, 444, 260);

    Media media = new Media(mediaURI);
    MediaPlayer mediaPlayer = new MediaPlayer(media);
    mediaPlayer.setCycleCount(MediaPlayer.INDEFINITE);
    mediaPlayer.setAutoPlay(true);

    // create mediaView and add media player to the viewer
    MediaView mediaView = new MediaView(mediaPlayer);
    mediaView.setScaleX(0.92);
    mediaView.setScaleY(0.92);
    mediaView.setX(-23);
    mediaView.setY(-13);
    root.getChildren().add(mediaView);
    fxPanel.setScene(scene);
    fxPanel.setVisible(true);
}

public static void removeMyVideoPlayer() {
    Platform.setImplicitExit(false);
}}

I am playing video by creating

new MyVideoPlayer(myPanel, mediaURI);

and I am stopping it by calling

MyVideoPlayer.removeMyVideoPlayer();

After a couple of successful iterations my application freezes and stop responding.

Please advise what I am doing wrong here? Maybe some better solution for this problem?

Thanks.
