将 .m4a 文件转换为 .mp3 时出现此错误

Question

我在如图所示运行脚本时遇到此错误

TEST.py

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

wav_audio.export("audio1.mp3", format="mp3")

错误如下图

Answer 1

运行前pip install ffmpeg

pip install ffmpeg-python

Answer 2

即使添加了 ffmpeg 的依赖项，也很可能无法读取文件。由于 pydub 不读取 .m4a 文件。主要是因为 'ffmpeg' 不通过 'libav' 库支持这种类型的文件。

我也有这个问题。

Answer 3

我得到了解决方案。如果你已经安装了ffmpeg或者ffmpeg-python。卸载它。因为它不会工作运行这个命令

pip uninstall ffmpeg
pip uninstall ffmpeg-python

现在转到这个linkhttps://ffmpeg.org/download.html

从这里下载ffmpeg并安装到C:\ffmpeg 然后转到环境变量并在路径中添加一个新路径 - C:\ffmpeg\bin 由于此路径包含 ffmpeg.exe 就是这样

现在假设您有 TEST.m4a 文件要转换为 TEST.mp3 只需复制并粘贴文件名和运行下面的脚本。注意：bewlo .py 文件应与 TEST.m4a 位于同一目录中，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。 :) 如果我的回答不清楚，请在此处告诉我，或者您可以发邮件给我 - kartikeyvaish99@gmail.com
