你好，我有一个MP4视频，我想使用ffmepg更改creation_time，而不更改其余的元数据。但是我面临一些问题。。
大多数品牌和更多的东西都改变了。我希望这些都是一样的。如果我把它放在ffprobe.exe中，这就是我看到的：
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from '6.mp4':

当我运行时，我想更改视频的creation_time
ffmpeg.exe-i 6.mp4-元数据创建时间="；2013-06-22 15:00:00"-acodec复制-vcodec复制输出.mp4
我得到：

根据输出-acodec拷贝-vcodec拷贝"；一切都应该保持不变。但是当我为新创建的.mp4文件运行ffprobe时。这是输出：
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'output.mp4':

minor_version : 512

b/s

正如你所看到的，一切都变了，尽管我选择保持一切不变。
请帮我一下。谢谢
现有的解决方案使用python脚本。
-
安装Python 3.3.2（它可能与2.7系列的最后一个兼容，但未经过测试）
-
从GitHub 下载movmd.py
movmd.py可以更改mp4中的所有日期（非常快）
python movmd.py mp4File.mp4 "2013-07-29 00:00:00"
用ffmpeg提取了mp4信息，我得到了：
