java读取视频时长
最近需要用java处理视频文件，读取视频的时长，在网上查，没找到合适的方法，用JMF吧，支持的格式太少，用JNI去读取其他语言写的API，但比较麻烦。无意中找到了jave这个开源的项目，看了看介绍，是用java来处理多种视频格式之间的转换的，下载了下来，看了看，还真找到了获取视频时长的方法。记录下来，给需要朋友做个参考。
下载jave的网址http://www.sauronsoftware.it/projects/jave/index.php
总共只有一个jar包，API也非常简单，不说了，贴代码：
package com.jave;
import it.sauronsoftware.jave.Encoder;
import it.sauronsoftware.jave.MultimediaInfo;
import java.io.File;
public class ReadVideo {
