获取视频时长

解决办法：
      调用DLL文件，只要找到一个可以比较好解析播放时长的DLL，然后JNI调用，CPP或者Delphi都好，只要能实现就oK了，DLL放在BIN目录；

public class CtrlFtpFile {
	//读取Dll
	static {
		System.loadLibrary("GetPlayTime");
	}

	public native String getMediaTime(String arg);

	public static void main(String[] args) {

		CtrlFtpFile hw = new CtrlFtpFile();
//		System.out.println(hw.getMediaTime("D:\\TDDOWNLOAD\\小强.mp3"));
		System.out.println(hw.getMediaTime("file:///G:/tomcat/apache-tomcat-6.0.18/webapps/mbs/ftp/0/real/B1224487037153.mpeg"));
		//file:///G:\tomcat\apache-tomcat-6.0.18\webapps\mbs\ftp\0/real/B1224487037153.mpeg
		
	}
}
