将嵌入式媒体播放器组件添加到 JPanel 时出错

Question

我尝试使用此代码在简单的 jframe 上显示视频：

package com.company;

import javax.swing.*;
import java.awt.*;

import uk.co.caprica.vlcj.player.component.EmbeddedMediaPlayerComponent;

public class Main {

    static EmbeddedMediaPlayerComponent myMedia = new EmbeddedMediaPlayerComponent();

    public static void main(String[] args) {
        JFrame j = new JFrame("Stream player");

        JPanel jp = new JPanel();
        jp.setBounds(0, 0, 700, 300);
        jp.setLayout(null);

        myMedia.mediaPlayer().media().start("C:\Users\cikko\Downloads\Video\144.mp4");
        myMedia.setBounds(0, 0, 700, 280);

        jp.setBackground(Color.BLACK);
        jp.add(myMedia);

        j.add(jp);

        j.setSize(700, 300);
        j.setLayout(null);
        j.setVisible(true);
    }

}

但它给出了错误。我尝试更改 jpanel 布局，但它也没有用。如何解决？谢谢

在播放媒体之前，您必须使框架可见。
