运行程序，利用ffmpeg将mp4转成wav报错

二·、原因与解决方法

文件路径中包含空格，你需要在命令行中将这个路径用引号括起来。以下是修改后的代码

import subprocess

def convert_mp4_to_wav(mp4_path, wav_path):
    command = f'ffmpeg -i "{mp4_path}" -vn -acodec pcm_s16le -ac 1 -ar 44100 -f wav "{wav_path}"'
    subprocess.call(command, shell=True)

# 测试函数
mp4_path = r'L:\webTTS\acdb\roles\Hina Suguta\Marin Kitagawa\4.mp4'
wav_path = r'L:\webTTS\audio.wav'
convert_mp4_to_wav(mp4_path, wav_path)

利用“”将含有空格的文件路径框起来，bug解决
