空閑 python Mac 上的 Ffmpeg

Question

我正在嘗試在 macOS Catalina 上的空閑 3.7.4 python 上使用 FFMPEG。

我運行brew install ffmpeg並成功安裝。

但是，當我轉到 IDLE 並運行我的腳本時（該腳本是將 .mp3 文件轉換為 .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")

這是我得到的回報：

  File "/Library/Frameworks/Python.framework/Versions/3.7/lib/python3.7/site-packages/pydub/utils.py", line 165
    warn("Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work", RuntimeWarning)

Answer 1

您的 python 執行環境無法找到您的 ffmpeg 安裝。 因為我只是簡單地復制粘貼了您的代碼並且它可以工作。

你的錯誤字面意思是No such file or directory: 'ffprobe': 'ffprobe'

還有一個警告： Couldn't find ffmpeg or avconv - defaulting to ffmpeg, but may not work

請檢查您的腳本正在執行的環境。 也許 IDLE 正在做某事。 嘗試通過終端運行您的腳本，您可以在其中獲得ffmpeg和ffprobe的輸出：

python3 script_file.py
