C:\Users\Administrator>youtube-dl
Usage: youtube-dl [OPTIONS] URL [URL...]

youtube-dl: error: You must provide at least one URL.
Type youtube-dl --help to see a list of all options.

3）下载ffmpeg组件：

备注:

如果不需要音频与视频文件合并时，是不需要安装该组件的。

官网地址：http://ffmpeg.org/

下载后，我把它解压到了D盘根目录下D:\ffmpeg-20170915-6743351-win64-static，找到目录：

将地址“D:\ffmpeg-20170915-6743351-win64-static\bin”追加到环境变量PATH后边，之后打开cmd运行窗口下运行ffmpeg -version来查看是否安装成功：

4）FQ软件下载运行：

同学给的FQ软件，下载后直接解压运行即可，IE下找到它的默认代理ip及端口号，记录下，后边有可能需要使用：

使用youtube-dl下载

1）打开“FQ”软件来启用系统代理，系统代理模式设置为全局模式，打开cmd，输入youtube-dl -F youtube视频链接，回车，会显示该视频可以下载的视频格式与分辨率。

youtube-dl -F http://www.youtube.com/watch?v=ozVRGho-cZQ
或者
youtube-dl --proxy socks5://127.0.0.1:8580 -F http://www.youtube.com/watch?v=ozVRGho-cZQ

其中上边是一个列表：第一列为format code（视频编码格式）、第二列为extension（视频文件扩展名）、第三列为resolution （分辨率）、第四列为note（描述信息）

绿色背景：这些都是单纯的音频（无视频）；

黄色背景：这些都是单纯的视频（无声音）；

蓝色背景：这些是音频&视频文件。

2）如何下载，借鉴《http://blog.csdn.net/u011475134/article/details/71023612》中的下载脚本：

文件名命名为：run_youtube-dl.bat

@echo off
:start
set /p dir=请输入保存路径：
set dir=%dir:/=\%
pushd %dir%
if /i not %dir%==%cd% goto :start
echo 保存路径：%cd%
:download
set /p input=请输入视频链接：
set input=%input:&=^^^&%
youtube-dl -F %input%
if errorlevel 1 goto :download
set /p code=请输入视频格式编号：
youtube-dl -f %code% %input%
goto :download

因此如果需要简单的下载，就可以直接选择“蓝色背景”这块的视频下载即可，但是这里的分辨率是有限的。

那么，如何实现自定义选择音频和视频本地组合呢？这个将在下边的例子中体现。

其中，如果需要单纯下载一个音频|视频文件，只需要在“请输入视频格式编号”输入“format code”对应的编号就可以。

但是，如果需要下载一个视频和一个音频文件，之后让它们两个文件合并，这就需要再在“请输入视频格式编号” 输入视频文件的“format code”+音频文件的“format code”，既可。

注意：

正是视频和音频文件合并这种情况下才会使用到“ffmpeg组件”，否则你可以不安装。

实际操作：运行“run_youtube-dl.bat”，之后一步一步的操作即可。
