使用you-get下载youtube视频

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'

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!
