Java获取文件中视频的时长

    public void ReadVideoTime(String path) {

        long sum = 0;

        long num = 0;

        File source = new File(path[i]);

        Encoder encoder = new Encoder();

        File[] file = source.listFiles();

        for (File file2 : file) {

            try {

                MultimediaInfo m = encoder.getInfo(file2);

                long ls = m.getDuration() / 1000;// ls是获取到的秒数

                sum += ls;

                num++;

            } catch (Exception e) {

                e.printStackTrace();

            }

        }

        double sum1 = (double) sum;

        double sum2 = sum1 / 3600;// 转换成为了小时

        System.out.println(sum2);

        System.out.println(num);

    }
