1、环境配置
(1)下载VLC VlC官网http://www.videolan.org/ 各个版本的下载地址http://download.videolan.org/pub/videolan/vlc/last/ 里面有32位和64位的区分,按照自己的系统下载对应的vlc版本,下载解压后提取;
(2)下载VLCJ (http://capricasoftware.co.uk/#/projects/vlcj)把下载文件解压后将其目录下的jna-3.5.2.jar、platform-3.5.2.jar、vlcj-3.8.0.jar(不同版本后缀数字可能会不同)三个文件复制到对应的java工程目录(新建 lib 文件夹)下;
(3)下载slf4j(http://www.slf4j.org/),下载文件后解压将其目录下的slf4j-api-1.7.13.jar、slf4j- nop-1.7.13.jar(不同版本后缀数字可能会不同)两个文件复制到对应的java工程目录(新建 lib 文件夹)下;
(4)将vlc安装目录下的libvlc.dll、libvlccore.dll 两个文件以及plugins问佳佳复制到对应的java工程目录下;
将lib文件中的jar包导入到工程项目中。配置好的项目目录如下图所示
(5)具体代码如下
播放器主类代码
package deng.test; import java.awt.EventQueue; import java.io.File; import javax.swing.JFileChooser; import javax.swing.SwingWorker; import com.sun.jna.Native; import com.sun.jna.NativeLibrary; import uk.co.caprica.vlcj.binding.LibVlc; import uk.co.caprica.vlcj.runtime.RuntimeUtil; public class PlayerMain { static Window frame; private static int times=1; private static boolean flag=true; // private static final String NATIVE_LIBRARY_SEARCH_PATH = "D:\Program // Files\VideoLAN\VLC\sdk\lib"; public static void main(String[] args) { // 环境配置,将vlc sdk导入到eclipse // if(RuntimeUtil.isWindows()){ } // NativeLibrary.addSearchPath(RuntimeUtil.getLibVlcLibraryName(), // "D:\vlc\vlc-2.2.6\sdk\lib"); //导入的路径是vlc的安装路径 NativeLibrary.addSearchPath(RuntimeUtil.getLibVlcLibraryName(), "vlcj//lib"); // 导入的路径是vlc的安装路径 Native.loadLibrary(RuntimeUtil.getLibVlcLibraryName(), LibVlc.class); // System.out.println(LibVlc.INSTANCE.libvlc_get_version()); // 创建主程序界面运行窗体 EventQueue.invokeLater(new Runnable() { @Override public void run() { try { frame = new Window(); frame.setVisible(true); frame.getMediaPlayer().playMedia("video//style.avi"); // 直接播放视屏,参数是视屏文件的绝对路径 // frame.getMediaPlayer().prepareMedia("video//test.mp4"); // //控制即将播放的视频 new SwingWorker<String, Integer>() { @Override protected String doInBackground() throws Exception { // TODO Auto-generated method stub while (flag) { // 获取视频播放进度并且按百分比显示 long total = frame.getMediaPlayer().getLength(); if(total==-1){//如果视频播放完,循环播放视频 play(); times++; System.out.println(times+"******************"); } 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.getProgressBar().setValue(v); } } }.execute(); } catch (Exception e) { e.printStackTrace(); } } }); } //关闭播放器释放资源 public static void dispose(){ flag=false; frame.getMediaPlayer().stop(); frame.dispose(); } // 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()); } } // 退出播放 public static void exit() { frame.getMediaPlayer().release(); System.exit(0); } // 实现播放按钮的方法 public static void play() { frame.getMediaPlayer().play(); } // 实现暂停按钮的方法 public static void pause() { frame.getMediaPlayer().pause(); } // 实现停止按钮的方法 public static void stop() { frame.getMediaPlayer().stop(); } // 实现点击进度条跳转的方法 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); } }
播放器窗体类:
package deng.test; import java.awt.BorderLayout; import java.awt.event.ActionEvent; import java.awt.event.ActionListener; import java.awt.event.MouseAdapter; import java.awt.event.MouseEvent; import javax.swing.JButton; import javax.swing.JFrame; import javax.swing.JMenu; import javax.swing.JMenuBar; import javax.swing.JMenuItem; import javax.swing.JPanel; import javax.swing.JProgressBar; import javax.swing.JSlider; import javax.swing.border.EmptyBorder; import javax.swing.event.ChangeEvent; import javax.swing.event.ChangeListener; import uk.co.caprica.vlcj.component.EmbeddedMediaPlayerComponent; import uk.co.caprica.vlcj.player.embedded.EmbeddedMediaPlayer; @SuppressWarnings("serial") public class Window extends JFrame{ private JPanel contentPane; //顶层容器,整个播放页面的容器 private JMenuBar menuBar; //菜单栏 private JMenu mnFile,mnSetting,mnHelp; //文件菜单 private JMenuItem mnOpenVideo,mnExit; //文件菜单子目录,打开视屏、退出 private JPanel panel; //控制区域容器 private JProgressBar progress; //进度条 private JPanel progressPanel; //进度条容器 private JPanel controlPanel; //控制按钮容器 private JButton btnStop,btnPlay,btnPause; //控制按钮,停止、播放、暂停 private JSlider slider; //声音控制块 EmbeddedMediaPlayerComponent playerComponent; //媒体播放器组件 public static void main(String[] args) { } //MainWindow构造方法,创建视屏播放的主界面 public Window(){ setTitle(" 小婷婷专属播放器 Copyright@dengchaoqun"); setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); setBounds(200,80,900,600); contentPane=new JPanel(); contentPane.setBorder(new EmptyBorder(5, 5, 5, 5)); contentPane.setLayout(new BorderLayout(0,0)); setContentPane(contentPane); /*视频播放窗口中的菜单栏*/ menuBar=new JMenuBar(); setJMenuBar(menuBar); mnFile=new JMenu("文件"); //设置菜单名 menuBar.add(mnFile); mnSetting=new JMenu("设置"); menuBar.add(mnSetting); mnHelp=new JMenu("帮助"); menuBar.add(mnHelp); mnOpenVideo =new JMenuItem("打开文件"); //设置文件菜单子目录打开文件 mnFile.add(mnOpenVideo); mnExit =new JMenuItem("退出"); //设置文件菜单子目录退出 mnFile.add(mnExit); //打开文件 mnOpenVideo.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub PlayerMain.openVideo(); } }); //退出 mnExit.addActionListener(new ActionListener() { @Override public void actionPerformed(ActionEvent e) { // TODO Auto-generated method stub PlayerMain.exit(); } }); /*视屏窗口中播放界面部分*/ JPanel videoPane=new JPanel(); contentPane.add(videoPane, BorderLayout.CENTER); videoPane.setLayout(new BorderLayout(0,0)); playerComponent=new EmbeddedMediaPlayerComponent(); videoPane.add(playerComponent); /*视屏窗口中控制部分*/ panel=new JPanel(); //实例化控制区域容器 videoPane.add(panel,BorderLayout.SOUTH); progressPanel=new JPanel(); //实例化进度条容器 panel.add(progressPanel, BorderLayout.NORTH); //添加进度条 progress=new JProgressBar(); progressPanel.add(progress); //panel.add(progress,BorderLayout.NORTH); progress.addMouseListener(new MouseAdapter() { @Override public void mouseClicked(MouseEvent e){ //点击进度条调整视屏播放进度 int x=e.getX(); PlayerMain.jumpTo((float)x/progress.getWidth()); } }); progress.setStringPainted(true); controlPanel=new JPanel(); //实例化控制按钮容器 panel.add(controlPanel,BorderLayout.SOUTH); //添加停止按钮 btnStop=new JButton("停止"); btnStop.addMouseListener(new MouseAdapter() { @Override public void mouseClicked(MouseEvent e) { // TODO Auto-generated method stub PlayerMain.stop(); } }); controlPanel.add(btnStop); //添加播放按钮 btnPlay=new JButton("播放"); btnPlay.addMouseListener(new MouseAdapter() { @Override public void mouseClicked(MouseEvent e) { // TODO Auto-generated method stub PlayerMain.play(); } }); controlPanel.add(btnPlay); //添加暂停按钮 btnPause=new JButton("暂停"); btnPause.addMouseListener(new MouseAdapter() { @Override public void mouseClicked(MouseEvent e) { // TODO Auto-generated method stub //PlayerMain.dispose(); PlayerMain.pause(); } }); controlPanel.add(btnPause); //添加声音控制块 slider=new JSlider(); slider.setValue(80); slider.setMaximum(100); slider.addChangeListener(new ChangeListener() { @Override public void stateChanged(ChangeEvent e) { // TODO Auto-generated method stub PlayerMain.setVol(slider.getValue()); } }); controlPanel.add(slider); } //获取播放媒体实例(某个视频) public EmbeddedMediaPlayer getMediaPlayer() { return playerComponent.getMediaPlayer(); } //获取进度条实例 public JProgressBar getProgressBar() { return progress; } }
效果如下:
(6)在视频播放面板上操作视频接口方法:
playerComponent = new EmbeddedMediaPlayerComponent(); panel.add(playerComponent); //视频表面的鼠标事件监听 playerComponent.getVideoSurface().addMouseListener(new MouseListener() { @Override public void mouseReleased(MouseEvent e) { // TODO Auto-generated method stub } @Override public void mousePressed(MouseEvent e) { // TODO Auto-generated method stub } @Override public void mouseExited(MouseEvent e) { // TODO Auto-generated method stub } @Override public void mouseEntered(MouseEvent e) { // TODO Auto-generated method stub } @Override public void mouseClicked(MouseEvent e) { // TODO Auto-generated method stub System.out.println("**************"); } });
(7)项目总结:应用了开源vlc,运用了jna技术,实现了多媒体视频播放。
