我想将一堆位于桌面上的音乐文件（但是第一步只是尝试将其中的一个文件转换）从.aif转换为.mp3，但是我从ffmpeg收到错误代码1。
我已经安装了ffmpeg和pydub
代码：
from os import path
from pydub import AudioSegment
from pydub.utils import which
AudioSegment.converter = which("ffmpeg")
aif_audio = AudioSegment.from_file("C:/Users/Nick/Desktop/scratch/landonmusic1.aif", format="aif")
aif_audio.export("C:/Users/Nick/Desktop/scratch/landonmusic1.mp3", format="mp3")
我从Python Terminal收到以下反馈：
S C:\Users\Nick\OneDrive\ProgrammingProjects> & C:/Users/Nick/AppData/Local/Programs/Python/Python37-32/python.exe c:/Users/Nick/OneDrive/ProgrammingProjects/Classes/MusicFileConverter.py
Traceback (most recent call last):

File "C:\Users\Nick\AppData\Local\Programs\Python\Python37-32\lib\site-packages\pydub\audio_segment.py", line 704, in from_file
p.returncode, p_err))
pydub.exceptions.CouldntDecodeError: Decoding failed. ffmpeg returned error code: 1
ffmpeg / avlib的输出：
