python - 将 MP3 转换为 WAV 时出现 2 个错误

Question

我正在尝试使用 pyglet 模块播放 mp3 文件。按照一些建议，我已经安装了 avbin64 并将 avbin64.dll 移动到我的 python 代码所在的目录。但是，我仍然收到 2 个错误

import pyglet

music = pyglet.resource.media('song.mp3')
music.play()

pyglet.app.run()

错误代码

Traceback (most recent call last):
  File "F:\PycharmProjects\test\venv\lib\site-packages\pyglet\media\codecs\wave.py", line 59, in __init__
    self._wave = wave.open(file)
  File "C:\Users\udit\AppData\Local\Programs\Python\Python37\lib\wave.py", line 510, in open
    return Wave_read(f)
  File "C:\Users\udit\AppData\Local\Programs\Python\Python37\lib\wave.py", line 164, in __init__
    self.initfp(f)
  File "C:\Users\udit\AppData\Local\Programs\Python\Python37\lib\wave.py", line 131, in initfp
    raise Error('file does not start with RIFF id')
wave.Error: file does not start with RIFF id

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "F:/PycharmProjects/test/test2.py", line 3, in <module>
    music = pyglet.resource.media('song.mp3')

    return media.load(path, streaming=streaming)

    raise first_exception

    raise WAVEDecodeException(e)

Answer 1

根据 "Loading media" ，您应该使用 pyglet.media.load 打开音频(和视频)文件:

music = pyglet.media.load('song.mp3')

您还必须为 pyglet 安装 ffmpeg 才能读取 mp3 文件(根据 Supported media types )。确保遵循 installation instructions .
