您是否看到过霍乔尔(Hachoir)?它从多媒体文件中提取元数据".
Have you seen Hachoir? It 'extracts metadata from multimedia files'.
不同的文件格式解析器会提供不同级别的详细信息，但这可能正是您所需要的.这是从AVI文件中提取元数据的示例:
The different file format parsers give differing levels of detail, but it might be what you are looking for. Here's an example of metatdata extraction from an AVI file:
$ hachoir-metadata pacte_des_gnous.avi
