将.m4a文件转换为.mp3时出现此错误

Question

我在运行如所示的脚本时遇到此错误

测试

from pydub import AudioSegment
wav_audio = AudioSegment.from_file("Broken Summer.m4a", format="m4a")
wav_audio.export("audio1.mp3", format="mp3")    

错误如下所示

C:Pythonlibsite-packagespydubutils.py:170: RuntimeWarning: Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work

Answer 1

即使添加了ffmpeg的依赖项，文件也很可能无法读取。由于pydub不读取.m4a文件。主要是因为"ffmpeg"不支持通过"libav"库的这种类型的文件。

我在这方面也遇到了麻烦。

Answer 2

pip在操作前安装ffmpeg。

pip install ffmpeg-python

Answer 3

我得到了解决方案。如果您已经安装了ffmpeg或ffmpeg-python。卸载它。因为它不起作用运行此命令

pip uninstall ffmpeg
pip uninstall ffmpeg-python

现在转到此链接https://ffmpeg.org/download.html

从这里下载ffmpeg并将其安装在C:\ffmpeg中然后转到"环境变量"，在"路径"中添加一个新路径，名称为-C:\ffmpeg\bin由于此路径包含ffmpeg.exe就是

现在假设您有TEST.m4a文件，要将其转换为TEST.mp3只需复制并粘贴文件名，然后运行以下脚本。注意：bewlo.py文件应该与TEST.m4a在同一目录中，否则您需要在"CurrentFileName"变量中添加正确的路径现在只需创建一个.py文件并粘贴此代码

import subprocess
CurrentFileName = 'TEST.m4a'
FinalFileName = 'TEST.mp3'
try:
subprocess.call(['ffmpeg', '-i', f'{CurrentFileName}', f'{FinalFileName}'])
except Exception as e:
print(e)
print('Error While Converting Audio')
ch = input('Press Enter to Close')

这完全符合我的要求。：(如果我的答案不清楚，请在这里告诉我，或者你可以给我发邮件[e-mail]
