我想使用
http://snipplr.com/view/4025/mp3-checksum-in-id3-tag/中的脚本为我的 mp3 收藏配备 md5 校验和。该脚本可以添加一个自定义 ID3 标签来保存音频数据的校验和，并且它还具有删除该校验和的选项。不幸的是，由于多种原因，添加和删除校验和无法通过往返测试。我想改变它。一个原因是脚本运行时会创建一个“标记时间”字段，但在删除校验和时不会删除该字段，甚至会更新时间。IIUC 该--no-tagging-time-frame选项将阻止命令行上的 eyed3 工具执行此操作，但我找不到 python 等效项。如何防止在 python 中更改或设置标记时间？
更多细节：
我在原始文件的副本上添加并随后删除了校验和，并比较了两个文件。这是最佳情况下二进制数据的差异：

在其他文件中引入了更多更改，当第一个问题解决后，我将回到那个问题。
