python 视频下载神器(you-get)的具体使用

you-get是github上python的一个开源库(https://github.com/soimort/you-get)，使用you-get你只需要取得视频所在网页链接地址就可以很轻松的下载下来，目前you-get所支持的网站包含国内外几十个网站(youtube、twitter、腾讯、爱奇艺、优酷、bilibili等)，基本上可以满足你的需求。

1.you-get可以直接通过命令行使用

前提是你要先安装you-get：pip install you-get

下载命令：you-get  your-url

l例如：

you-get https://www.bilibili.com/bangumi/play/ep118488?from=search&seid=5050973611974373611

效果如下：（我直接在pycharm的终端命令行执行）

2.通过python 简单调用you-get库

 # 视频网站的地址

 # 视频输出的位置
 path = "G:/test"
 download(url, path)

3.python 简单集成 tkinter，通过GUI的形式展现（单线程，未做优化，后续做优化处理）

注：由于视频窗口是单线程，所以下载过程会一直卡顿（是正常的，因为处于下载中，下载完后会恢复），后续将会优化
