我的目标是创建一个将 AVI 文件作为输入的程序，然后执行任何必要的操作将其刻录到 DVD。
目前，我使用三个独立的程序来完成此任务。第一个工具需要我将它从 AVI 文件转换为 MPEG。第二个工具采用 MPEG 并创建 DVD 文件（一个 VIDEO_TS 文件夹，其中包含一些文件）。第三个工具将文件夹刻录到 DVD。我想将这三个工具合二为一，如果可能的话，跳过 AVI 到 MPEG 的转换，只创建 DVD 文件并刻录它们。
目标平台是 Windows 7，我要使用的语言是 C++。
哪些库或命令行程序将帮助我追求荣耀？
编辑：澄清一下，我想创建一个视频 DVD 来在 DVD 播放器上播放电影。（谢谢杰瑞）
编辑 2：我最终在 Linux 上使用 Python 来自动化一切。这是脚本以防万一有人需要它。（注意：这是我的第一个 python 脚本，所以它可能不是很好）
