所以基本上我想把我在webm中从youtube下载的歌曲转换成mp3
当我只想用song.export("neco.mp3")导出歌曲时，它不太适用
我在工作文件夹中有ffmpeg.exe和ffprobe.exe
这是代码
from pydub import AudioSegment
song = AudioSegment.from_file(downloaded.webm,"webm")
print("Loaded")
song.export("neco.mp3", format="mp3", bitrate="320k")
print("Converted and saved")
这是控制台的输出

我认为这是编解码器的问题，但我不知道该怎么做
在ffmpeg.exe(4.3.1(中也有类似的问题，
但在ffmpeg-20200802-b48397e-win64-static中一切都很好，
因为在那里的标准容器中没有使用mp3_mf(WAV/MP3在你的问题中，AVI在我的问题中(。
因此，如果您不能切换到不同的ffmpeg版本，
您应该强制它使用libmp3lame，而不仅仅是mp3
和使用(System？(-编解码器mp3_mf：
所以不要使用：-f mp3
而是使用(或添加(：-c:a libmp3lame
