Question

我一直在尝试寻找视频音频中音频无声空间的位置，但是我无法克服仅使用python 3中的pydub导入音频文件的问题

我已经尝试在项目中将pydub正在检查ffmpeg的目录更改为一个目录，并且该文件位于我正在运行脚本的目录中，但它似乎仍返回相同的错误。

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)

我希望它将mp3音频段存储到变量audi中，但它返回：

FileNotFoundError: [WinError 2] The system cannot find the file specified

print(AudioSegment.ffmpeg)

按预期返回

C：\ Users \ ratee \ PycharmProjects \ untitled \ ffmpeg \ bin \ ffmpeg.exe

print(my_file) returns

按预期返回

audio.mp3

并且代码在我尝试导入音频的位置停止运行

audio = AudioSegment.from_mp3（“ audio.mp3”）

Answer 1

我遇到了同样的问题，但是显然即使添加了ffmpeg路径，它仍然会给出相同的错误。我在Linux中尝试了此操作，没有使用AudioSegment.converter = 'path\to\ffmpeg'这样的附加命令，它工作正常，问题出在Windows IDE（pycharm，spyder等）上。尝试直接从Windows中的提示符（anaconda，cmd等）运行脚本。应该可以。

这不是一个尝试，只是出于比较原因而尝试重现OP错误的尝试。文件夹名称x，y用于缩短路径长度。

FileNotFoundError: [WinError 2] The system cannot find the file specified

以下代码：

AudioSegment.ffmpeg = os.getcwd()+"\\ffmpeg\\bin\\ffmpeg.exe"
print (AudioSegment.ffmpeg)

1）C：\ y \ ffmpeg \ bin \ ffmpeg.exe

并且：

my_file = Path("audio.mp3")
print (my_file)

给予：

2）audio.mp3

建议的解决方案 ：

包括以下特定代码行以指定ffmpeg的位置：

pydub.AudioSegment.converter = r"C:\\path\\to\\ffmpeg.exe"，其中 path \ to \ 是实际路径

你应该没事。

更新1 ：

引发您的错误是由于使用了“ my_file”中的文件名而不是AudioSegment.from_mp3(my_file)所要求的“ filepath”。通过提供文件路径，可以解决出现的 [WinError2] 问题。

在以下脚本中运行时，会发生AttributeError: 'WindowsPath' object has no attribute 'read'错误。该错误与pathlib相关，并且应该已经在pydub 0.22版本中进行了修复，如github上的here所述。我在Github上提出了issue。

引发的file.read()问题与python版本相关（2.7与3.5），因为它不再存在于内置库中。因此，.read()会触发AttributeError: 'WindowsPath' object has no attribute 'read'错误。

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.

Answer 3

我遇到了同样的问题。

pydub.AudioSegment.converter = os.getcwd()+ "\\ffmpeg.exe"                    
pydub.AudioSegment.ffprobe   = os.getcwd()+ "\\ffprobe.exe"
sound = pydub.AudioSegment.from_mp3(os.getcwd()+"\\sample.mp3")

一切正常

如何修复FileNotFoundError：[WinError 2]系统找不到用AudioSegment.from_mp3（）指定的文件
