自己用的，没有充分测试！1和2只可用于Windows，Linux下无效！

需要python 3.6及以上版本。

set_jpg_timestamp.py

 python set_jpg_timestamp.py "jpg文件夹路径（不包含结尾的/）"。

set_mp4_timetamp.py

用法（需使用第三方库：pypiwin32）：

 python set_mp4_timestamp.py "mp4文件夹路径（不包含结尾的/）"

mp4parse.py

用法1：

 from collections import deque
 from os.path import getsize

 from mp4parse import parser

 mp4file = 'xxx'
 s = deque()
 with open(mp4file, 'rb') as f:
     g = parser(s, f, 0, getsize(mp4file))
     for box_info, box_stacks in g:
         pass

用法2（需使用第三方库：asciitree）：

 python mp4parse.py "mp4文件"

输出："mp4文件"中所有的box的信息及层次关系，每个节点格式为：box_type (@offset, length)
