pydvdid的Python项目详细描述
概述
pydvdid是windows apiIDvdInfo2::GetDiscID方法的纯python实现，windows媒体中心使用它来计算用于元数据检索的“实际唯一”64位CRC。
动机
我需要一个零知识的方法来恢复一些关于插入的DVD或安装的ISO映像的基本信息，同时在搜索中找到dvdid。编译后的解决方案不符合我的要求，所以我将其重新实现为一个python模块。克里斯托弗·基因最初开发了dvdid并将算法记录得如此彻底而受到赞誉。
PYDVDID可用于DVD翻录脚本、自定义咆哮通知和媒体中心相关的家庭自动化任务。
兼容性
适用于python版本2和3，从2.6到夜间构建。

来自python：
pydvdid有一个非常简单的api，其中重要的位导入到包级别，因此可以方便地直接从包中导入。
