Ffmpeg on idle python Mac

问题

I am trying to use FFMPEG on idle 3.7.4 python on macOS Catalina.

I ran brew install ffmpeg and it successfully installed.

However, when I go to IDLE and run my script (the script is to convert a .mp3 file to a .wav):

from os import path
from pydub import AudioSegment    

src = "transcript.mp3"
dst = "test.wav"         

sound = AudioSegment.from_mp3(src)
sound.export(dst, format="wav")

This is what I get in return:

Warning (from warnings module):
  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pydub/utils.py", line 165
    warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)

回答1:

Your python execution environment is not able to find your ffmpeg installation. Because I simply copy pasted your code and it works.

Your error literally says No such file or directory: 'ffprobe': 'ffprobe'

There's also a warning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work

please check the environment in which your script is executing. Maybe IDLE is doing something. Try running your script via the terminal in which you get an output for ffmpeg and ffprobe as:

python3 script_file.py
