用pydub访问ff探头

Question

我试图让https://github.com/jiaaro/pydub在Docker的AlpinLinux3.7.3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'

我用诗歌加上了ff探针和相关的ffmpeg软件包，这一切似乎都很好：

 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]

关于如何使这些内容在https://github.com/jiaaro/pydub/issues/62中可用，有很多讨论

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

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'

关于如何使这个包可供pydub使用，有什么想法吗？

对我来说，当我将FFMPEG二进制文件复制到拥有Mp3文件的同一个目录中时，它起了作用。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。
