python - 在 python 中找不到可执行文件 'ffmpeg'

Question

我正在尝试使用 python 压缩视频，但是有一个错误，我无法理解如何解决它，所以你能帮我吗？
我附上了一张图片和代码enter image description here

import ffmpy

input_name = input("Enter name of input file: ")
crf = int(input("Enter constant rate factor between 18 and 24: "))
output_name = input("Enter output file name: ")
inp = {input_name: None}
outp = {output_name: '-vcodec libx264 -crf %d'%crf}     #video  codec and compression rate
ff = ffmpy.FFmpeg(inputs=inp, outputs=outp)             #creates an FFmpeg object
print(ff.cmd)                                           #just to verify that it produces the correct ffmpeg command
ff.run()                                                #does the compression
print("done!")

运行，我明白了

Enter name of input file: newproject.mp4
Enter constant rate factor between 18 and 24: 20
Enter output file name: "com.mp4"
ffmpeg -i newproject.mp4 -vcodec libx264 -crf 20 com.mp4
Traceback (most recent call last):

    ff.run()                                                #does the compression

ffmpy 的包依赖项之一是 ffmpeg .事实上ffmpy是 ffmpeg 的包装器.要解决您的问题，请使用 pip 安装 ffmpeg .
