简介和安装

Nginx 本身是一个非常出色的HTTP服务器，OBS (Open Broadcaster Software) 是一个免费且开源的，全平台支持的视频录制和直播软件。这两个东西通过一个nginx的模块nginx-rtmp-module组合在一起，即可以搭建一个功能流媒体服务器。这个流媒体服务器可以支持RTMP和HLS(Live Http Stream)。

FFmpeg也是一个非常优秀的音视频解决软件。但OBS的界面更加友好，且支持屏幕捕获，所以我选择OBS。其实是因为FFmpeg没有GUI界面，所以我懒得再去研究它。

关于Nginx的安装，可以参考这里。在Linux端的Nginx与RTMP模块的安装，可以参考这里。RTMP模块的Github地址在这里，你可以在这里看到更为详尽的使用说明。

作者在Windows环境下搭建服务器，并且仅仅以最简单的方式实现作者需要的功能。

配置

假定你已经安装好了Nginx和RTMP插件，现在是使用它的时候了。

首先，定义一个Nginx的配置文件nginx-win-rmtp.conf。

# location / {

# root html;

# index index.html index.htm;

# }

#}

}

挑重点的说，我们需要注意的是

rtmp {

server {

listen 1935;

chunk_size 4000;

application live {

live on;

}

}

}

此处的listen指的是你的rtmp开在了本地的哪个端口，当你需要链接服务器的时候，别忘了把端口号加上，如果设备处于内网，那么记得打开端口映射，防火墙选择放行。因为我们关注的只有rtmp服务器，所以无需关注其他端口。

OBS推流

打开OBS。

1.进入推流设置，将服务设置为“自定义”。

2.服务器设置为rtmp://IP:Port/APP。

3.串流秘钥不填写，作者不会使用权限控制的功能。想要进行权限设置，可以参考这里。

因为在配置文件中我们创建的app名字就叫live，所以在这里APP填写为live。如rtmp://192.168.1.110:1935/live。

运行

我写了一个Powershell脚本来运行nginx。可以在一个PS窗口中非常方便的运行和结束nginx。

该脚本默认nginx-win-rtmp.conf配置文件在nginx.exe目录下的\conf目录中。

而nginx.exe的路径在D:\Hider\Tools\FFmpeg+nginx+LIVE\nginx-1.7.11.3-Gryphon中，请根据实际情况自行修改。

cd "D:\Hider\Tools\FFmpeg+nginx+LIVE\nginx-1.7.11.3-Gryphon"

# 若nginx已经运行，则停止

Get-Process -Name "nginx" | Stop-Process

$job = Start-Job -ScriptBlock {

cd "D:\Hider\Tools\FFmpeg+nginx+LIVE\nginx-1.7.11.3-Gryphon";

.\nginx.exe -c conf\nginx-win-rtmp.conf;

}

Write-Host "Starting...`n"

sleep 2

Get-Job

Write-Host "`n"

Get-Process -Name "nginx" | Format-Table

do {

Write-Host "`nNginx is running, finish it?`n";

$exit = Read-Host "Type Y to finish";

Write-Host "`n"

} while ($exit -ne "Y")

Write-Host "Before:"

Get-Process -Name "nginx" | Format-Table

.\nginx.exe -s quit

# 先平稳关闭，若失败则强制结束进程

Get-Process -Name "nginx" | Stop-Process

sleep 1

Write-Host "`nAfter:"

Get-Process -Name "ngin*" | Format-Table

Write-Host "(It has been finished if there were no output.)"

Write-Host "`nNginx has been finished.`n"

pause

拉流

让OBS开始推流，如果一切都没有问题，此时应该是可以正常运行的。接下来，我们要让客户端拉取直播。

作者使用Potplayer，各个(靠谱的)播放器播放流的方法都大同小异：

1.菜单 - 打开 - 打开流(或 打开链接 等)

2.输入刚刚你推流的rtmp://网址，和OBS推流地址相同。

完成

到此为止，你应该已经成功的在本地搭建了一个简单的nginx直播服务器，并且能够正常观看。

十分感谢您的阅读，这是我第一次写博客，希望能够得到更多的指教，包括技术方面和写作方面的。
