使用you-get下载youtube视频
有时候需要从视频网站下载视频，很多软件都需要收费，最近发现一个可以免费下载视频完整开源工具you-get，支持视频网站比较多，废话不多说，先按说明搭建试试。虽然中间遇到很多坑，最终终于搞定。
1、环境搭建
下面是官网要求环境：
Prerequisites
The following dependencies are necessary:
安装python运行环境、下载FFmpeg（我这里是windows环境、下载后设置环境变量）详细步骤不在赘述。
2、安装you-get
官网介绍安装方式比较多，这里选择pip安装具体命令如下
pip3 install you-get
上面就完成you-get所有安装
3、开始使用
接着按照官网说明开始抓取视频文件，下面是官网实例：
$ you-get -i 'https://www.youtube.com/watch?v=jNQXAC9IVRw'
site: YouTube
title: Me at the zoo
streams: # Available quality and codecs

执行上面脚本报如下错误：
you-get: [error] oops, something went wrong.
you-get: don't panic, c'est la vie. please try the following steps:
you-get: (1) Rule out any network problem.
you-get: (2) Make sure you-get is up-to-date.
you-get: (3) Check if the issue is already known, on
you-get: https://github.com/soimort/you-get/wiki/Known-Bugs
you-get: https://github.com/soimort/you-get/issues
you-get: (4) Run the command with '--debug' option,
you-get: and report this issue with the full output.
增加debug日志、查找wiki发现视频地址参数不能用单引号，但是视频网站参数去掉单引号，国内视频可以正常下载，youtube还是不行（需要正确上网）。继续排查可以能需要代理，安装代理
pip3 install pysocks
抓取视频信息
you-get -i https://www.youtube.com/watch?v=MAXeCR7iNmU -s 127.0.0.1:1080 --debug
显示结果成功！
