空闲 python Mac 上的 Ffmpeg

Question

我正在尝试在 macOS Catalina 上的空闲 3.7.4 python 上使用 FFMPEG。

我运行brew install ffmpeg并成功安装。

但是，当我转到 IDLE 并运行我的脚本时（该脚本是将 .mp3 文件转换为 .wav）：

from os import path
from pydub import AudioSegment    

src = "transcript.mp3"
dst = "test.wav"         

sound = AudioSegment.from_mp3(src)
sound.export(dst, format="wav")

这是我得到的回报：

    warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)

Answer 1

您的 python 执行环境无法找到您的 ffmpeg 安装。 因为我只是简单地复制粘贴了您的代码并且它可以工作。

你的错误字面意思是No such file or directory: 'ffprobe': 'ffprobe'

还有一个警告： Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work

请检查您的脚本正在执行的环境。 也许 IDLE 正在做某事。 尝试通过终端运行您的脚本，您可以在其中获得ffmpeg和ffprobe的输出：
