我一直试图在视频的音频中找到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 正在检查 ffmpeg 的目录更改为项目中的一个目录,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 audi 中,但它返回:

按预期返回


print(my_file) returns

按预期返回



并且代码在我尝试导入音频时停止运行

最佳答案

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

重现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 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)



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

给出:



提议的解决方案 :

包括以下特定代码行以指定 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 :

您提出的错误是由于在“my_file”处使用了文件名,而不是 AudioSegment.from_mp3(my_file) 要求的“filepath”。通过提供文件路径,这修复了引发的 [WinError2] 问题。

当您在脚本下方运行时,会发生 AttributeError: 'WindowsPath' object has no attribute 'read' 错误。该错误与 pathlib 相关,应该已在 pydub 0.22 版本中修复,如 github 上的 here 所讨论的那样。我在 Github 上提出了 issue

提出的 file.read() 问题与 python 版本相关(2.7 与 3.5),因为它不再包含在其内置库中。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 同时解决错误 1 ​​和错误 2 中的问题。

在导入语句之后直接在脚本中包含以下几行:


mypaths = os.getenv('PATH').split(';')  # replace 'PATH' by 'your search path' if needed.

 for i in mypaths:
     if i.find('python'):
         print(i)

打印输出显示您是否包含 FFmpeg 文件的位置。如果不是,您需要重新启动 Windows,因为当您当前处于 python 环境/编辑器时,Windows 环境路径不会更新。

在我的情况下,重启后 c:\y\FFmpeg\ 出现在“PATH”下,错误一和二中的所有警告都消失了。
