我们经常会有各种影片,没有预览图,封面图,等等比如欧美大姐姐自制视频.这个时候怎么办呢?
我自己写了一个python脚本来自动截图
1.在群晖中添加第三方源:https://packages.synocommunity.com/
2.在源中找到ffmpeg 安装!
3.用新的源替换ffmpeg
mv /usr/bin/ffmpeg /usr/bin/ffmpeg_bak
cp -r /usr/local/ffmpeg/bin/ffmpeg /usr/bin/ffmpeg4.安装python3,安装源中的python3
如果你不想每次都输入地址可以使用
cp -r /usr/local/python3/bin/python3 /usr/bin/python3
5.复制粘贴我的截图I脚本

make_thumb()5.在吧这个python内容,复制到 你需要截图的视频的根目录,新建一个 jietu.py 会自动遍历所有子目录.并且在视频的位置,生成和视频文件同名的 .JPG文件.
6.在群晖中添加计划任务 python3 /web/jietu.py
