使用 pydub 访问 ffprobe

Question

我正在尝试让 https://github.com/jiaaro/pydub 在 Docker 中的 Alpine Linux 3.7.3 上使用 ffprobe 和 ffmpeg 解码器。

错误是：

/usr/lib/python3.6/site-packages/pydub/utils.py:198: RuntimeWarning: Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work
  warn("Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work", RuntimeWarning)
[Errno 2] No such file or directory: 'ffprobe': 'ffprobe'

我已经添加了 ffprobe 和相关的 ffmpeg 包，看起来一切正常：

 development  ➜ app  poetry show ffprobe
Skipping virtualenv creation, as specified in config file.
name         : ffprobe
version      : 0.5
description  : Wrapper around ffprobe command to extract metadata from media files
 development  ➜ app  poetry show ffmpeg
Skipping virtualenv creation, as specified in config file.
name         : ffmpeg
version      : 1.4
description  : ffmpeg python package url [https://github.com/jiashaokun/ffmpeg]

这里有很多关于如何使这些对 ffmpeg 可用的讨论https://github。com/jiaaro/pydub/issues/62

我一直按照建议手动设置 AudioSegment.converter、AudioSegment.ffmpeg 和 AudioSegment.ffprobe，包括使用 ipdb 以确保已设置：

ipdb> AudioSegment.converter
'/usr/lib/python3.6/site-packages/ffprobe/ffprobe.py'
ipdb> mp3_audio = AudioSegment.from_file(output, format="mp3")
/usr/lib/python3.6/site-packages/pydub/utils.py:198: RuntimeWarning: Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work
  warn("Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work", RuntimeWarning)
*** FileNotFoundError: [Errno 2] No such file or directory: 'ffprobe': 'ffprobe'
ipdb> ffprobe
<module 'ffprobe' from '/usr/lib/python3.6/site-packages/ffprobe/__init__.py'>
ipdb> AudioSegment.ffmpeg
<module 'ffmpeg' from '/usr/lib/python3.6/site-packages/ffmpeg/__init__.py'>
ipdb> AudioSegment.ffprobe
'/usr/lib/python3.6/site-packages/ffprobe/ffprobe'
ipdb> AudioSegment.ffprobe = '/usr/lib/python3.6/site-packages/ffprobe/ffprobe.py'
ipdb> mp3_audio = AudioSegment.from_file(output, format="mp3")
/usr/lib/python3.6/site-packages/pydub/utils.py:198: RuntimeWarning: Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work
  warn("Couldn't find ffprobe or avprobe - defaulting to ffprobe, but may not work", RuntimeWarning)
*** FileNotFoundError: [Errno 2] No such file or directory: 'ffprobe': 'ffprobe'

关于如何使该包可用于 pydub 的任何想法？

Answer 1

对我来说，当我将 FFMPEG 二进制文件复制到我拥有 Mp3 文件的同一目录时，它就起作用了。我尝试调整路径变量等，但最后复制二进制文件对我有用。您可以从这里下载 ffmpeg 二进制文件：https://ffmpeg.org/download.html
