使用SwingNode在JavaFX中显示VlcJ [英] Display VlcJ in JavaFX using SwingNode

问题描述

FXMLController初始化方法：

FXMLController initialize method:

@FXML
private VBox vbContainer;
MediaPlayerVLC m_mediaPlayer;

public void initialize(URL url, ResourceBundle rb) {
        final SwingNode swingNode = new SwingNode();

        m_mediaPlayer = new MediaPlayerVLC();
        createAndSetSwingContent(swingNode, m_mediaPlayer);

        vbContainer.getChildren().add(0, swingNode);
    }

和createAndSetSwingContent（）：

And createAndSetSwingContent():

private void createAndSetSwingContent(final SwingNode swingNode, JComponent jComponent) {
        SwingUtilities.invokeLater(new Runnable() {
            @Override
            public void run() {
                swingNode.setContent(jComponent);
            }
        });
    }

MediaPlayerVLC类：

MediaPlayerVLC class:

package javafxswing;

import javax.swing.JPanel;
import uk.co.caprica.vlcj.component.EmbeddedMediaPlayerComponent;

public class MediaPlayerVLC extends JPanel {

    private final EmbeddedMediaPlayerComponent mediaPlayerComponent;

    public MediaPlayerVLC() {

        setSize(350, 320);
        setVisible(true);        
        mediaPlayerComponent = new EmbeddedMediaPlayerComponent();
        mediaPlayerComponent.setSize(350, 320);
        add(mediaPlayerComponent);
    }

    public MediaPlayer getMediaPlayer() {
        return mediaPlayerComponent.getMediaPlayer();
    }
}

我点击一个按钮播放媒体FXMLController：

And I play the media by clicking a button, in FXMLController:

@FXML
private void handleButtonAction(ActionEvent event) {
     System.out.println("You clicked me!");
     m_currentVideo = "video.mov";
     m_mediaPlayer.getMediaPlayer().playMedia(m_currentVideo);
}

现在，问题是：视频开始播放但我看不到图像。我说它开始播放因为我能听到音频。我做错了什么？

Now, the problem: The video starts to play but I can see no image. I say it starts to play because I can hear the audio. What am I doing wrong?

任何帮助高度赞赏。

推荐答案

简而言之，它不会以这种方式工作。

In short, it won't work this way.

来自Javdoc的 SwingNode 这里： http://docs.oracle.com/javase/8/ javafx / api / javafx / embed / swing / SwingNode.html

From the Javdoc for SwingNode here: http://docs.oracle.com/javase/8/javafx/api/javafx/embed/swing/SwingNode.html

它表示部分：

JComponent实例中包含的组件层次结构不应包含任何重量级组件，否则SwingNode可能无法绘制它。

The hierarchy of components contained in the JComponent instance should not contain any heavyweight components, otherwise SwingNode may fail to paint it.

在vlcj的情况下， EmbeddedMediaPlayerComponent 扩展 Panel ，一个重量级的AWT组件。

In the case of vlcj, the EmbeddedMediaPlayerComponent extends Panel, a heavyweight AWT component.

要与vlcj一起使用JavaFX，您可能需要自己直接渲染视频数据。这就是vlcj所谓的 DirectMediaPlayerComponent 的用途。这种方法的本质是 DirectMediaPlayerComponent 接收要渲染的每帧视频数据，然后你自己使用 PixelWriter 或你提出的其他一些方法。

To use with vlcj with JavaFX you will likely have to render the video data directly yourself. This is what vlcj's so-called DirectMediaPlayerComponent is for. The essence of this approach is that the DirectMediaPlayerComponent receives each frame of video data to render, and you would then render this yourself using a PixelWriter or some other means that you come up with.

这里有一个vlcj-javafx项目 https://github.com/caprica/vlcj-javafx ，这种方法适用于Java7。由于错误的线程，它不能与Java8一起使用，在此处记录： https://github.com / caprica / vlcj-javafx / issues / 3

There is a vlcj-javafx project here https://github.com/caprica/vlcj-javafx, and this approach works up to Java7. It does not work with Java8 due to wrong threading, documented here: https://github.com/caprica/vlcj-javafx/issues/3
