將MP3轉換為WAV時出現2個錯誤

Question

我正在嘗試使用pyglet模塊播放mp3文件。 按照一些建議，我已經安裝了avbin64，並將avbin64.dll移到了我的python代碼所在的目錄中。 但仍然出現2個錯誤

import pyglet

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

pyglet.app.run()

錯誤代碼

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')

Answer 1

按照“加載媒體” ，您應該使用pyglet.media.load打開音頻（和視頻）文件：

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

您還必須安裝ffmpeg才能使pyglet能夠讀取mp3文件（根據支持的媒體類型 ）。 確保遵循安裝說明 。
