在MacOS上为MoviePy安装ffmpeg失败，并显示SSL错误 [英] ffmpeg installation on macOS for MoviePy fails with SSL error

问题描述

我正在尝试编写一个Python程序，该程序在Mac OS 10.11.16上使用MoviePy将MP4文件转换为GIF.我使用:

I'm trying to write a Python program that uses MoviePy on Mac OS 10.11.16 to convert an MP4 file to GIF. I use:

import moviepy.editor as mp

，我收到一条错误消息，说我需要致电imageio.plugins.ffmpeg.download()，以便我可以下载ffmpeg.我使用:

and I get an error saying I need to call imageio.plugins.ffmpeg.download() so I can download ffmpeg. I use:

import imageio
imageio.plugins.ffmpeg.download()

这给了我以下错误:

Imageio: 'ffmpeg.osx' was not found on your computer; downloading it now.

我肯定有互联网连接.我找到了此链接，并尝试使用Homebrew和Static版本进行安装，但均未成功.对于我自己来说，似乎编译起来有点太高级了(我只是简要地研究了一下).我在IDLE上使用了imageio.plugins.ffmpeg.download().我读到一些有关使用PyCharm运行MoviePy代码的信息，但出现相同的初始错误. ffmpeg当前在我的/usr/local/bin文件夹中.欢迎任何建议.感谢您的帮助.

I definitely have an internet connection. I found this link, and tried installing with Homebrew and Static builds, but neither have worked. It seems like compiling it myself would be a little too advanced for me (I've only briefly looked into it). I used imageio.plugins.ffmpeg.download() on IDLE. I read something about using PyCharm to run the MoviePy code, but I get the same initial error. ffmpeg is currently in my /usr/local/bin folder. Any suggestions are welcome. Thank for your help.

我正在使用Python 3.6.1

推荐答案

我能够通过调试提取脚本找到macOS的解决方法:

1. 手动下载构建的文件(这是发生SSL错误的地方): https://github.com/imageio/imageio -binaries/raw/master/ffmpeg/ffmpeg-osx-v3.2.4

1. manually download the built (this is where the SSL error occurs): https://github.com/imageio/imageio-binaries/raw/master/ffmpeg/ffmpeg-osx-v3.2.4

将文件粘贴到以下路径:/Users/yourusername/Library/Application\ Support/imageio/ffmpeg/

paste the file to the path: /Users/yourusername/Library/Application\ Support/imageio/ffmpeg/

重新运行代码

什么不能解决我的问题:

• 使用pip升级moviepy，然后通过导入movie.editor
提示ffmpeg下载
• 明确导入imageio并执行imageio.plugins.ffmpeg.download()
• brew install ffmpeg

what didn't solve my problem:

• upgrading moviepy with pip, then prompting the ffmpeg download through importing movie.editor
• explicitly importing imageio and executing imageio.plugins.ffmpeg.download()
• brew install ffmpeg
