java 获取视频的时长、大小、格式等信息

1、最近有一个小的视频处理需求，根据传入视频的url获取视频的时长、大小、格式等信息。下面将记录一下：

package Void;

/**

import it.sauronsoftware.jave.Encoder;
import java.io.File;
import java.io.FileInputStream;
import java.io.IOException;
import java.math.BigDecimal;
import java.math.RoundingMode;
import java.nio.channels.FileChannel;
import java.util.HashMap;
import java.util.Map;

public class VoidUtils {
	public static void main(String[] args){
		File source = new File("http://flv4.people.com.cn/videofile3//CCTV1/2018/1/14/CCTV1_1500000_20181114_30322514_0_113_android_l.mp4");
		Encoder encoder = new Encoder();
		FileChannel fc= null;
		String size = "";
		try {
			it.sauronsoftware.jave.MultimediaInfo m = encoder.getInfo(source);
			long ls = m.getDuration();
			System.out.println("此视频时长为:"+ls/60000+"分"+(ls)/1000+"秒！");
			//视频帧宽高
			System.out.println("此视频高度为:"+m.getVideo().getSize().getHeight());
			System.out.println("此视频宽度为:"+m.getVideo().getSize().getWidth());
			System.out.println("此视频格式为:"+m.getFormat());
			FileInputStream fis = new FileInputStream(source);
			fc= fis.getChannel();
			BigDecimal fileSize = new BigDecimal(fc.size());
			size = fileSize.divide(new BigDecimal(1048576), 2, RoundingMode.HALF_UP) + "MB";
			System.out.println("此视频大小为"+size);
		}catch (Exception e) {
			e.printStackTrace();
		}finally {
			if (null!=fc){
				try {
					fc.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
	}
	
	/**
	 * @param path
	 * @return Map
	 */
	public static Map getVoideMsg(String path){
		
		Map map = new HashMap();
		File file = new File(path);
		Encoder encoder = new Encoder();
		FileChannel fc= null;
		String size = "";
		
		if(file != null){
			try {
				it.sauronsoftware.jave.MultimediaInfo m = encoder.getInfo(file);
				long ls = m.getDuration();
				
				FileInputStream fis = new FileInputStream(file);
				fc= fis.getChannel();
				BigDecimal fileSize = new BigDecimal(fc.size());
				size = fileSize.divide(new BigDecimal(1048576), 2, RoundingMode.HALF_UP) + "MB";
				
				map.put("height", m.getVideo().getSize().getHeight());
				map.put("width", m.getVideo().getSize().getWidth());
				map.put("format", m.getFormat());
			}catch (Exception e) {
				e.printStackTrace();
			}finally {
				if (null!=fc){
					try {
						fc.close();
					} catch (IOException e) {
						e.printStackTrace();
					}
				}
			}
		}
		
		return map;	
	}
}

该工具类需要的依赖：

			it.sauronsoftware
			jave
			1.0.2
			system
			${project.basedir}/src/main/resources/lib/jave-1.0.2.jar
		
		
		
			commons-codec
			commons-codec
			1.10
		


		
		
			org.apache.httpcomponents
			httpclient
			4.3.1
		

其中jave-1.0.2.jar 这个maven中没有 ，需要自己下载：

下载后在resource下创建lib放在里面

此时因为是外部包 不是maven自带的需要scope内system
${project.basedir}/src/main/resources/lib/jave-1.0.2.jar为项目中jar的路径

			it.sauronsoftware
			jave
			1.0.2
			system
			${project.basedir}/src/main/resources/lib/jave-1.0.2.jar
		

当scope为system的时候打包不会自动打包进去的，所以要添加一个参数才能打包进去的
