Java获取文件中视频的时长

    public voidReadVideoTime(String path) {
        long sum = 0;
        long num = 0;
        File source = newFile(path[i]);
        Encoder encoder = newEncoder();
        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);
    }
