ppt2mp4 (Python2.7)

将ppt文件转成mp4视频。GitHub

前提

1.需要Windows系统，并且启用了Windows多媒体播放器。需要安装Office 2010已上版本。因为PowerPoint把ppt转成视频需要依赖Windows多媒体播放器，如果没启用的话需要从设置里启用桌面体验功能。启用步骤可以参考：https://www.omnivex.com/suppo...

使用

1.安装Office 2010或更高版本

2.启用桌面体验功能(如果没启用的话)。

3.编辑convert.py，修改ppt_path,mp4_path路径，然后运行python convert.py。
