多媒体播放器1

 

最终的视频播放器的实现：

主要功能：

（1） 通过查找文件，打开本地视频

（2） 通过代理打开视频（需要服务计算的相关知识）

（3） 暂停，后退，前进

（4） 视频的进度条，点击进度条视频跳转到相应的位置

（5） 调节音量

（6） 其他功能可以自己添加

1． VLCJ

vlcj项目提供了一个Java框架，允许将本机VLC媒体播放器的实例嵌入到Java AWT窗口或Swing JFrame中。VLCJ学习网址：http://capricasoftware.co.uk/#/projects/vlcj/tutorial

2.VLCJ的配置

（1）下载vlc视频播放器，因为要使用里面的库函数。直接百度下载即可。

（2）http://capricasoftware.co.uk/#/projects/vlcj/tutorial/installation去这个地址下载相应的jar包

（3）配置完成后，可以做一个测试

package tutorial;

import uk.co.caprica.vlcj.binding.LibVlc;

import uk.co.caprica.vlcj.discovery.NativeDiscovery;

public class Tutorial {

public static void main(String[] args) {

boolean found = new NativeDiscovery().discover();

System.out.println(found);

System.out.println(LibVlc.INSTANCE.libvlc_get_version());

}

}

 

3.配置完成后就可以使用VLCJ写程序了

（1）创建视频播放器的窗口代码，为了代码更加具有可读性，把控件和控件对应的事件分开写。

各种事件的添加可以查看文档：

http://caprica.github.io/vlcj/javadoc/2.2.0/overview-summary.html

最主要的就是

EmbeddedMediaPlayerComponent mediaPlayerComponent;的使用

创建播放器窗口

videoName = new String[f.length];

i = 0;

for (File m : f) {

videoName[i++] = m.getName();

length++;

System.out.println(length);

}

}

public Window() {

frame = new JFrame("视频播放");

frame.setBounds(100, 100, 800, 600);

frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);

frame.addWindowListener(new WindowAdapter() {

@Override

public void windowClosing(WindowEvent e) {

mediaPlayerComponent.release();

System.exit(0);

}

});

menuBar = new JMenuBar();

setJMenuBar(menuBar);

mnFile = new JMenu("文件"); // 设置菜单名

menuBar.add(mnFile);

menuBar.add(service);

getVideoName();

for (int i = 0; i < length; i++) {

service.add(videoName[i]);

}

mnOpenVideo = new JMenuItem("打开文件"); // 设置文件菜单子目录打开文件

mnFile.add(mnOpenVideo);

mnOpenVideo.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

// TODO Auto-generated method stub

mainPlay.openVideo();

}

});

// 退出

mnExit.addActionListener(new ActionListener() {

@Override

public void actionPerformed(ActionEvent e) {

// TODO Auto-generated method stub

mainPlay.exit();

}

});

for (i = 0; i < length; i++) {

}

});

}

public MediaPlayer getMediaPlayer() {

// TODO Auto-generated method stub

return mediaPlayerComponent.getMediaPlayer();

}

public JProgressBar getProgerss() {

return progress;

}

}

 

（2）添加相应的事件

package 视频播放器;

import java.awt.EventQueue;
import java.io.File;

import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.SwingWorker;

import uk.co.caprica.vlcj.discovery.NativeDiscovery;
import video.VideoDir;
import video.VideoService;
import video.VideoServiceService;

public class mainPlay {
	static Window frame;
	private String dirVideo;

	public static void main(String[] args) {

		new NativeDiscovery().discover();

		// 创建主程序界面运行窗体
		EventQueue.invokeLater(new Runnable() {

			@Override
			public void run() {
				// TODO Auto-generated method stub
				try {
					frame = new Window();
					//frame.getMediaPlayer().playMedia("src/环保小视频.mp4"); // 控制播放视屏
					new SwingWorker<String, Integer>() {

						protected String doInBackground() throws Exception {
							// TODO Auto-generated method stub
							while (true) { // 获取视频播放进度并且按百分比显示
								long total = frame.getMediaPlayer().getLength();
								long curr = frame.getMediaPlayer().getTime();
								float percent = (float) curr / total;
								publish((int) (percent * 100));
								Thread.sleep(100);
							}
							// return null;
						}

						protected void process(java.util.List<Integer> chunks) {
							for (int v : chunks) {
								frame.getProgerss().setValue(v);
							}
						}
					}.execute();
				} catch (Exception e) {
					e.printStackTrace();
				}
			}
		});
	}

	

	//打开文件  
    public static void openVideo() { 
    	
        JFileChooser chooser=new JFileChooser();  
        int v=chooser.showOpenDialog(null);  
        if(v==JFileChooser.APPROVE_OPTION){  
            File file=chooser.getSelectedFile();  
            frame.getMediaPlayer().playMedia(file.getAbsolutePath());  
        }  
    }  
    public static void openVideo(String dir){
    	File file=new File(dir);
    	frame.getMediaPlayer().playMedia(file.getAbsolutePath()); 
    }
    //退出播放  
    public static void exit() {  
        frame.getMediaPlayer().release();  
        System.exit(0);  
    }  
	// 实现暂停按钮的方法
	public static void pause() {
		frame.getMediaPlayer().pause();
	}
	// 实现点击进度条跳转的方法
	public static void resume(){
		frame.getMediaPlayer().skip(-1000);
	}
	public static void skip(){
		frame.getMediaPlayer().skip(10000);
	}
	
	public static void jumpTo(float to) {
		frame.getMediaPlayer().setTime((long) (to * frame.getMediaPlayer().getLength()));
	}

	// 实现控制声音的方法
	public static void setVol(int v) {
		frame.getMediaPlayer().setVolume(v);
	}
}

（3）要想程序正常的运行有两种方法。

方法一：删除服务相关的内容，把服务对应的事件删除即可

方法二：学习服务计算相关知识

推荐选择方法二
