JAVA项目（一）——基于VLC的简易视频播放器

1.下载并安装与系统适配的VLC版本；

2.将如下以下文件添加到lib中，并添加到build path中；

注：采用jna-4的版本的时候，可能会出现找不到vlc的报错的兼容性问题，可采用换为低版本的jna解决；

3.创建两个类，一个为窗体，一个为主程序。

主程序：

package com.caihui.videoplayer.main;

import java.awt.EventQueue;

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

import com.caihui.videoplayer.views.MainWindow;
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 PlayMain {//程序开启的方法

	static MainWindow frame;
	
	public static void main(String[] args) {
		// TODO Auto-generated method stub
		NativeLibrary.addSearchPath(RuntimeUtil.getLibVlcLibraryName(), "C:\\Program Files\\VideoLAN\\VLC");//VLC的外部库路径		
		Native.loadLibrary(RuntimeUtil.getLibVlcLibraryName(),LibVlc.class);//加载
		
		//创建窗体
		EventQueue.invokeLater(new  Runnable() {
			public void run() {
				try {
					frame = new MainWindow();
					frame.setVisible(true);
					String options[] = {"--subsdec-encoding=GB18030"};//声明中文编码
					frame.getMediaPlayer().prepareMedia("video//2、工程创建与配置.mp4",options);//准备媒体文件
					new SwingWorker() {
						
						@Override
						protected String doInBackground() throws Exception {
							// TODO Auto-generated method stub
							while(true) {
							long totalTime = frame.getMediaPlayer().getLength();//获取视频长度，以毫秒记，长整型
							long currentTime = frame.getMediaPlayer().getTime();//目前的进度
							float percent = (float)currentTime/totalTime;
							publish((int)(percent*100));
							Thread.sleep(100);
							}
						};
				
						
						protected void process(java.util.List chunks) {
							for (int v : chunks) {
								frame.getprograssBar().setValue(v);
							}
						};
		
					}.execute();
					
				} catch (Exception e) {
					// TODO Auto-generated catch block
					e.printStackTrace();
				}
			}
		});
	}
	
	public static void play() {
		frame.getMediaPlayer().play();
	}
	
	public static void pause() {
		frame.getMediaPlayer().pause();
	}
	public static void stop() {
		frame.getMediaPlayer().stop();;
	}
	public static void jumpto(float to) {
		frame.getMediaPlayer().setTime((long)(to*frame.getMediaPlayer().getLength()));
	}
	public static void openVideo() {
		JFileChooser chooser = new JFileChooser();
		int v = chooser.showOpenDialog(null);
		if (v == JFileChooser.APPROVE_OPTION) {
			java.io.File file =chooser.getSelectedFile();
			frame.getMediaPlayer().playMedia(file.getAbsolutePath());
			
		}
	}
	
	public static void opensubtitle() {
		JFileChooser chooser = new JFileChooser();
		int v = chooser.showOpenDialog(null);
		if (v == JFileChooser.APPROVE_OPTION) {
			java.io.File file =chooser.getSelectedFile();
			frame.getMediaPlayer().setSubTitleFile(file.getAbsolutePath());
			
		}
		
	}
	
	public static void exit() {
		frame.getMediaPlayer().release();
		System.exit(0);
	}
	
	public static void setVol(int v) {
		frame.getMediaPlayer().setVolume(v);
	}
	
}

主要实现功能：播放，暂停，停止，音量调节，进度调节，文件打开菜单栏等。
