【问题描述】:
我想使用 python ffmpeg 或 moviepy 将 mp4 视频文件转换为 mp3/wav 音频。 当我运行这个命令时
ffmpeg -i vid.mp4 -ar 44100 -vn audio.wav
返回
Output file #0 does not contain any stream
这是完整的日志

我在互联网上搜索过,但找不到解决方案
请告诉是否有办法用 ffmpeg 或其他方式做到这一点
我也尝试使用moviepy,但没有成功。
这里是moviepy日志
Traceback (most recent call last):
File "path\to\file\script.py", line 3, in <module>
clip.audio.write_audiofile(r'audio.mp3')
AttributeError: 'NoneType' object has no attribute 'write_audiofile'
这是我的moviepy代码
import moviepy.editor as mp
clip = mp.VideoFileClip('vid.mp4')
clip.audio.write_audiofile(r'audio.mp3')
【问题讨论】:
-
您的视频似乎缺少音频
-
是的,我的音频文件有音频
-
嗯 ffmpeg 不这么认为 :) 你能公开分享视频文件吗?
