已安装FFmpeg但PyDub无法定位问题求助（Windows11环境）

环境配置 #

• Windows 11系统
• Python 3.10.6
• PyDub 0.25.1
• FFmpeg版本：2023-04-12-git-1179bb703e-full_build

问题详情 #

已通过命令行确认FFmpeg安装配置正确并加入系统环境变量，其他依赖FFmpeg的模块（如moviepy）可正常运行，但使用PyDub加速MP3时，始终出现找不到FFmpeg的错误。即使在代码中手动指定FFmpeg绝对路径AudioSegment.ffmpeg_path = r"C:\ffmpeg\bin\ffmpeg.exe"，问题仍未解决。

尝试的代码 #

import os
from pydub import AudioSegment

file = r'test.mp3'

# 加载MP3文件
audio = AudioSegment.from_file(file, format="mp3")

# 加速音频
audio = audio.speedup(playback_speed=2, chunk_size=150)

# 导出修改后的文件覆盖原文件
audio.export(file, format="mp3")

# 删除原文件
os.remove(file)

其他模块验证（moviepy正常运行） #

from moviepy.editor import ColorClip

# 创建一个5秒的黑色视频片段
empty_clip = ColorClip(size=(640, 480), color=(0, 0, 0), duration=5)

# 将片段导出为视频文件
empty_clip.write_videofile("empty.mp4", codec="libx264", fps=25)
