在JPanel中嵌入vlcj播放器 [英] Embed vlcj player in JPanel

问题描述

我正在尝试在jpanel中添加vlcj播放器.

Hi I am trying to add a vlcj player in a jpanel.

我正在使用这篇文章和

I am using this post and this post to realise this. I am also using a tutorial on how to use embeddedMediaPlayerComponent for this. I already got this working where the video is played in a JFrame. I want to place the vlcj-player in a JPanel now, but I am still getting erroneous behavior.

这是我在jframe中的主类代码

Here is my code of the main class with the jframe in

import java.awt.BorderLayout;
import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.util.ArrayList;
import java.util.Observable;

import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.SwingUtilities;

import com.sun.jna.NativeLibrary;

import uk.co.caprica.vlcj.component.EmbeddedMediaPlayerComponent;
import uk.co.caprica.vlcj.runtime.RuntimeUtil;

public class VlcPlay extends JFrame {

public static void main(final String[] args) {
    SwingUtilities.invokeLater(new Runnable() {
        @Override
        public void run() {
            new VlcPlay();
        }
    });
}

private VlcPlay() {
    this.setTitle("Test");

    /* Initialize the JFrame */
    this.setLocation(100, 100);
    this.setSize(1050, 600);
    this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);

    TestClass p = new TestClass(); // The panel

    this.add(p, BorderLayout.CENTER); // Add the panel

    this.setVisible(true);

    p.play();


}
}

这是嵌入媒体播放器的代码:

And this is the code where the mediaplayer is embedded :

import java.awt.BorderLayout;
import java.awt.Canvas;
import java.awt.Color;

import javax.swing.JPanel;

import com.sun.jna.NativeLibrary;

import uk.co.caprica.vlcj.component.EmbeddedMediaPlayerComponent;
import uk.co.caprica.vlcj.player.MediaPlayerFactory;
import uk.co.caprica.vlcj.player.embedded.EmbeddedMediaPlayer;
import uk.co.caprica.vlcj.runtime.RuntimeUtil;


public class TestClass extends JPanel {
private EmbeddedMediaPlayerComponent ourMediaPlayer;
TestClass(){
    NativeLibrary.addSearchPath(RuntimeUtil.getLibVlcLibraryName(), "C:\\Program Files\\VideoLAN\\VLC");

    ourMediaPlayer = new EmbeddedMediaPlayerComponent();



    /* Set the canvas */
    Canvas c = new Canvas();
    c.setBackground(Color.black);
    c.setVisible(true);

    /* Set the layout */
    this.setLayout(new BorderLayout());

    /* Add the canvas */
    this.add(c, BorderLayout.CENTER);
    this.setVisible(true);



}
public void play() {
    /* Play the video */
    ourMediaPlayer.getMediaPlayer().playMedia("Movie on 25-04-14 at 11.41.mp4");

}
}

我得到的错误如下:

任何帮助将不胜感激！

谢谢.
