python - Pydub wma to mp3 修复“库配置不匹配”

Question

Python新手，希望改变这一点。

我正在尝试将歌曲从 wma 转换为 mp3，同时将元数据保留在歌曲上。这是我的代码。

#musicproject.py
import os
import glob
from pydub import AudioSegment

music_dir ='/mnt/c/renameproject'
extension_list = ('*.wma')

os.chdir(music_dir)
for extension in extension_list:
    for song in glob.glob(extension):
        mp3_filename = os.path.splitext(os.path.basename(song))[0] + '.mp3'
        AudioSegment.from_file(song).export(mp3_filename, format='mp3')

程序结束，歌曲在同一个文件夹中以 mp3 格式写入，播放效果很好。不幸的是，所有元数据都已从歌曲中删除。运行程序时，我在命令行收到以下警告。我对这个问题的理论是，就元数据库而言，pydub 和 ffmpeg 之间存在不匹配，因此 pydub 提供了 ffmpeg 不理解的东西，所以它会呕吐。我完全不知道从这里采取什么步骤来修复它。任何面包屑将不胜感激。谢谢。

File "./musicproject.py", line 12, in <module>
    AudioSegment.from_file(song).export(mp3_filename, format='mp3')
  File "/home/tom/.local/lib/python2.7/site-packages/pydub/audio_segment.py", line 725, in from_file
    p.returncode, p_err.decode(errors='ignore') ))
pydub.exceptions.CouldntDecodeError: Decoding failed. ffmpeg returned error code: 1
