需要先下载 ffmpeg, 把代码里面 ffmpeg.exe 的位置改了
把上面的文件放到跟视频同级目录下，然后执行
python convert.py 测试视频.mp4 C:
上面的C:是输出路径，可以改成别的
如果需要批量执行，可以用PowerShell，代码示例：
Get-ChildItem F:tmp | ForEach-Object -Process{ if($_ -is [System.IO.FileInfo] -and $_.Extension.ToString() -eq ".mp4") { Write-Host($_.name); python convert.py $_.name F:Capture }}
