下面这段 ahk 代码，"把 ffmpeg 加到 path 里面"和"mp4 文件不要带空格“两个要求满足的时候应该就可以批量转了

#Requires AutoHotkey v2.0
#SingleInstance Force

; Get list of files matching a prefix under a folder.

video_files.Push(A_LoopFileName)

ffmpeg_rotate(video_file){

Run concat4("ffmpeg -display_rotation:v:0 90 -i ", video_file, " -c copy rotated_", video_file)
}

concat3(x, y, z) {
Return x y z
}

concat4(w, x, y, z) {
Return w x y z
}
