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

Question

我一直在尝试找到视频音频中音频静音空间的位置，但我无法通过在 python 3 中使用 pydub 导入音频文件

我已经尝试将 pydub 检查 ffmpeg 的目录更改为项目内的目录，并且该文件位于我运行脚本的目录中，但它似乎仍然返回相同的错误。

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 音频段存储到变量中，audi但它返回：

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

音频.mp3

并且代码在我尝试导入音频时停止运行

音频 = AudioSegment.from_mp3("audio.mp3")

Answer 1

出于比较原因，答案的第一部分尝试重现 OP 错误。此后通过更新 1 找到解决方案，最后通过更新 2 找到解决方案。文件夹名称 x、y 用于缩短路径长度。

复制它给我带来了以下错误：

错误一：

c:\x\lib\site-packages\pydub\utils.py:165: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work
      warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)
c:\x\lib\site-packages\pydub\utils.py:193: RuntimeWarning: Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work
      warn("Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work", RuntimeWarning)

错误二：

    Traceback (most recent call last):
      File "C:\y\lol.py", line 16, in <module>
        audi = AudioSegment.from_mp3("audio.mp3")
      File "c:\x\lib\site-packages\pydub\audio_segment.py", line 716, in from_mp3
        return cls.from_file(file, 'mp3', parameters=parameters)
      File "c:\x\lib\site-packages\pydub\audio_segment.py", line 665, in from_file
        info = mediainfo_json(orig_file)
      File "c:\x\lib\site-packages\pydub\utils.py", line 263, in mediainfo_json
        res = Popen(command, stdin=stdin_parameter, stdout=PIPE, stderr=PIPE)
      File "c:\x\lib\subprocess.py", line 676, in __init__
        restore_signals, start_new_session)
      File "c:\x\lib\subprocess.py", line 957, in _execute_child
        startupinfo)
    FileNotFoundError: [WinError 2] The system cannot find the file specified

下面的代码是检查是否可以找到ffmpeg和ffprobe：

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

1) C:\y\ffmpeg\bin\ffmpeg.exe

和：

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

给出：

2) 音频.mp3

建议的解决方案：

包含以下特定代码行来指定 ffmpeg 所在的位置：

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：

您遇到的错误是由于在“my_file”中使用文件名而不是AudioSegment.from_mp3(my_file). 通过提供文件路径，这可以修复引发的[WinError2]问题。

当您运行下面的脚本时，AttributeError: 'WindowsPath' object has no attribute 'read'会发生错误。该错误与 pydub 0.22 版本相关pathlib，并且应该已在github 上讨论的 pydub 0.22 版本中修复。我已经在 Github 上提出了这个问题。

提出的问题file.read()与 python 版本相关（2.7 与 3.5），因为它不再位于其内置库中。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.

更新2：

由于更新 1 解决了平台版本问题，如果更新 1 中的解决方案 1 尚未解决，则更新 2 会同时解决错误一和错误二中的问题。

在导入语句之后直接在脚本中包含以下行：

    Traceback (most recent call last):
      File "C:\y\lol.py", line 16, in <module>
        audi = AudioSegment.from_mp3("audio.mp3")
      File "c:\x\lib\site-packages\pydub\audio_segment.py", line 716, in from_mp3
        return cls.from_file(file, 'mp3', parameters=parameters)
      File "c:\x\lib\site-packages\pydub\audio_segment.py", line 665, in from_file
        info = mediainfo_json(orig_file)
      File "c:\x\lib\site-packages\pydub\utils.py", line 263, in mediainfo_json
        res = Popen(command, stdin=stdin_parameter, stdout=PIPE, stderr=PIPE)
      File "c:\x\lib\subprocess.py", line 676, in __init__
        restore_signals, start_new_session)
      File "c:\x\lib\subprocess.py", line 957, in _execute_child
        startupinfo)
    FileNotFoundError: [WinError 2] The system cannot find the file specified

打印输出显示您是否已包含 FFmpeg 文件的位置。如果没有，您需要重新启动 Windows，因为当您当前处于 Python 环境/编辑器中时，Windows 环境路径不会更新。

就我而言，重新启动后c:\y\FFmpeg\出现在“PATH”下，错误一和错误二中的所有警告都消失了。
