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:Traceback (most recent call last):

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):

return cls.from_file(file, 'mp3', parameters=parameters)

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。关于python-3.x - 如何修复 FileNotFoundError : [WinError 2] The system cannot find the file specified with AudioSegment. from_mp3(),我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/55669182/
