问题
I've been trying to find the position of spaces of audio silence in the audio of a video, but I can't get past just importing an audio file with pydub in python 3
I've already tried changing the directory that pydub is checking for ffmpeg to one within the project, and the file is in the directory I'm running the script from but it still seems to return the same error.
from moviepy import editor
from pydub import silence, AudioSegment
from pathlib import Path
import os
AudioSegment.converter = r"C:\\Users\\ratee\\PycharmProjects\\untitled\\ffmpeg\\bin\\ffmpeg.exe"
vid = editor.VideoFileClip("video.mp4")
print(AudioSegment.ffmpeg)
my_file = Path("audio.mp3")
if not my_file.is_file():
vid.audio.write_audiofile("audio.mp3")
audio = AudioSegment.from_mp3("audio.mp3")
print(audio)
I expect it to store the mp3 audio segment into the variable audi but it returns:

audio.mp3
and the code stops running at the point where I try to import audio
audio = AudioSegment.from_mp3("audio.mp3")

First part of the answer tries to reproduce OPs error for comparison reason. Thereafter finding a solution via update 1 and finally update 2. The folder-names x, y are used to shorten pathlengths.
Reproducing it threw me the following errors:
Error One:

FileNotFoundError: [WinError 2] The system cannot find the file specified
The following code is to check if ffmpeg and ffprobe can be found:
AudioSegment.ffmpeg = os.getcwd()+"\\ffmpeg\\bin\\ffmpeg.exe"
print (AudioSegment.ffmpeg)
1) C:\y\ffmpeg\bin\ffmpeg.exe
And:
my_file = Path("audio.mp3")
print (my_file)
gives:
2) audio.mp3
Proposed solution:
Include the following specific codeline to specify where the ffmpeg is located:
pydub.AudioSegment.converter = r"C:\\path\\to\\ffmpeg.exe" where path\to\ is the actual path
And you should be fine.
Update 1:
You're raised error is due to the use of the filename at "my_file" and not "filepath" as required by AudioSegment.from_mp3(my_file). By providing the filepath this fixes the raised [WinError2] issue.
When you run below script the AttributeError: 'WindowsPath' object has no attribute 'read' error occurs. The error is related to pathlib and should have be been fixed in pydub 0.22 version as discussed here at github. I've raised the issue at Github.
The file.read() issue raised is python version related (2.7 vs. 3.5) because its nolonger in its build-in library. Therefore the .read() triggers the AttributeError: 'WindowsPath' object has no attribute 'read' error.
from pydub import silence, AudioSegment
from pathlib import Path
import os, sys
print (sys.version)
#AudioSegment.ffmpeg = os.getcwd()+"\\ffmpeg\\bin\\ffmpeg.exe"
AudioSegment.converter = r"C:\\x\\build\\win\\64\\ffmpeg.exe"
AudioSegment.ffprobe = r"C:\\x\\build\\win\\64\\ffprobe.exe"
#print (AudioSegment.converter)
#print (AudioSegment.ffprobe)
my_file = Path("C:\\y\\audio.mp3")
print ('ID1 : %s' % my_file)
audio = AudioSegment.from_mp3(my_file) # solves ***[WinError2]*** issue.
Update 2:
As update 1 solves a platform version issue update 2 solves the issue in error one and two at the same time if solution 1 in update 1 doesn't solve it yet.
Include in your script directly after the import statements the following lines:
mypaths = os.getenv('PATH').split(';') # replace 'PATH' by 'your search path' if needed.
for i in mypaths:
if i.find('python'):
print(i)
The printout shows you whether you have included the location of FFmpeg files or not. If not you need to reboot windows due to the fact the windows environment paths are not updated while you are currently in a python environment/editor.
In my case after reboot c:\y\FFmpeg\ showed up under 'PATH' and all warnings in error one and two were gone.
回答2:
I encountered the same problem but apparently even after adding ffmpeg path it still gives the same error. I tried this in Linux without extra commands like AudioSegment.converter = 'path\to\ffmpeg' it works fine, the problem is with Windows IDEs (pycharm, spyder, etc). Try running script directly from your prompt(anaconda, cmd, etc.) in windows. It should work.
