命令行下载软件ykdl介绍

鉴于上次You-get教程的介绍写到后面写不下去了。这次，简洁一点，不写那么详细。就一个简单的入门介绍。

一、绪论

ykdl是基于You-get开发的一个更适合国内用户使用的开源软件。因为是一个命令行软件，所以全平台可用（Win、Mac、linux等通通都可以）。同样基于 Python 3 。几乎可以下载网络上任何可以看的视频、可以听的音乐、可以看的图片。已测试支持的网站有腾讯、优酷、网易云等（因为我自己基本上都是用的IDM下载）。

二、准备工作

跟You-get一样需要以下软件作为前提

1、Python 3 （这是一个脚本语言，但是在这里我们可以很不负责任地把它理解为一个应用商店）

2、F Fmpeg （这是一个开源的格式工具，几乎所有的格式转换软件都内置了它。它在ykdl里的作用就是把从网络上下载下来的分段或者flv等视频转换成一个完整的MP4）

三、安装环境和软件

1、下载并安装 Python 3

点击上面链接，找到适合自己的版本。（如果访问缓慢或者无法访问，文末提供了文件下载）

2、下载并安装 F Fmpeg

可以有两种方法
（1）去官网下载，自己配置好环境。（不推荐。太麻烦，我懒得写。）
（2）直接用Python 3 安装

Windows用户打开Cmd或者Windows PowerShell（建议不要以管理员身份打开）
Mac用户打开终端
输入下面的代码，回车。等待安装完成。

pip3 install FFmpeg

3、安装ykdl

有很多种方式，我推荐直接用下面这行代码，windows和Mac通用

pip3 install ykdl

输入上面代码，回车。等待安装完成。

You are using pip version 19.0.3, however version 19.1.1 is available.
You should consider upgrading via the 'python -m pip install --upgrade pip' command.

到这里安装已经完成，接下来就是怎么使用了。

四、ykdl的使用

windows下使用cmd或者Windows PowerShell（建议不要以管理员身份打开），Mac下使用终端。

视频下载的格式如下：
ykdl 'https://v.qq.com/x/page/t066111fk0u.html'
音频下载同理。
这个语法默认下载最好画质的视频。

使用 -i 可以查看并选择可下载的视频尺寸和格式，语法如下：
ykdl -i 'https://v.qq.com/x/page/t066111fk0u.html'
这个语法还会列出视频的真实地址，可以复制到迅雷、IDM等下载软件下载。

1、如上，如果我们需要下载1080蓝光的视频，则只需要
ykdl --format=BD [URL]
即 ykdl --format=BD 'https://v.qq.com/x/page/t066111fk0u.html'
2、Real urls: 后面的是真实地址可以复制到下载工具下载。这个视频里面有五个分段，所以每个清晰度后面都有五个地址。

PS C:\Users\ZhouShiQi> ykdl --format=BD 'https://v.qq.com/x/page/t066111fk0u.html'
site:                腾讯视频 (QQ)
title:               直播吧！支书
artist:              None
streams:
    - format:        BD
      container:     mp4
      video-profile: 蓝光;(1080P)
      size:          557.3 MiB (584400736 bytes)
    # download-with: ykdl --format=BD [URL]

Download: 直播吧！支书_BD part 1
Download: 直播吧！支书_BD part 2
Download: 直播吧！支书_BD part 3
Download: 直播吧！支书_BD part 4
 100%

下载完正常情况下会将五个分段合成为一个Mp4视频。文件位置
在Win系统下一般在用户文件夹。比如上面就在 C:\Users\ZhouShiQi> 路径下面
在Mac系统下最近文件就可以找到
