Question

运行脚本时出现此错误

TEST.py

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

Answer 1

在操作之前先安装ffmpeg。

pip install ffmpeg-python

Answer 2

即使添加了ffmpeg的依赖关系，很可能也不会读取该文件。由于pydub无法读取.m4a文件。主要是因为'ffmpeg'通过'libav'库不支持此类文件。

我也有麻烦。

Answer 3

我找到了解决方案。如果已安装ffmpeg或ffmpeg-python。卸载它。由于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.zeranoe.com/builds/

从此处下载ffmpeg并将其安装在C：\ ffmpeg中然后转到“环境变量”，然后在“路径”中添加新路径为-C：\ ffmpeg \ bin 由于此路径包含ffmpeg.exe 就是这样

现在假设您有要转换为TEST.mp3的TEST.m4a文件只需复制并粘贴文件名并运行以下脚本。注意：bewlo .py文件应与TEST.m4a位于同一目录中，否则您将需要在'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')

这对我来说非常理想。 :) 如果我不清楚答案，请在此告诉我，或者您可以给我发送邮件-kartikeyvaish99@gmail.com
