8.public class ReadVideo {
9.
10. public static void main(String[] args){
11. File source = new File("E:\\测试视频\\R41.avi");
12. Encoder encoder = new Encoder();
13. try {
14. MultimediaInfo m = encoder.getInfo(source);
15. long ls = m.getDuration();
16. System.out.println("此视频时长为:"+ls/60000+"分"+(ls`000)/1000+"秒！");
17. } catch (Exception e) {
18. e.printStackTrace();
