跑制作精灵.py关于debian 9

Question

我试着跑制作精灵.py（https://github.com/vlanard/videoscripts/blob/master/sprites/makesprites.py）在.mp4文件上使用以下命令：

对于480/*.mp4中的f；执行python制作精灵.py$f；完成

我的ffmpeg版本： ffmpeg版本3.2.8-1~deb9u1版权所有（c）2000-2017 ffmpeg开发者 使用gcc 6.3.0（Debian 6.3.0-18）20170516构建

但我有个错误：

root@vps47509:~/test# for f in 480/*.mp4; do python makesprites.py $f; done
