一、使用 Nginx-rtmp-module 编译 Nginx

首先，我们需要通过Nginx-rtmp-module编译Nginx，推荐使用sergey-dryabzhinsky，该仓库一直在被积极开发中，相比于arut具有更多的修复与改进。

下载 Nginx-rtmp-module

git clone https://github.com/sergey-dryabzhinsky/nginx-rtmp-module.git	(Recommend)
git clone https://github.com/arut/nginx-rtmp-module.git					(original one)

安装 Nginx 依赖

sudo apt-get install build-essential libpcre3 libpcre3-dev libssl-dev

下载 Nginx

从 Nginx下载网站 选择最新的Nginx版本下载。
例如 nginx-1.24.0 可通过 https://nginx.org/download/nginx-1.24.0.tar.gz 获取。

wget https://nginx.org/download/nginx-1.24.0.tar.gz
tar -xf nginx-1.24.0.tar.gz
cd nginx-1.24.0

编译 Nginx

./configure --with-http_ssl_module --add-module=../nginx-rtmp-module   # Pay attention to the nginx-rtmp-module Path
make -j 1		# 1: The number of CPUs on U PC to accelerate the compilation
sudo make install

二、Nginx 配置文件

# 备份 nginx.conf
sudo cp /usr/local/nginx/conf/nginx.conf /usr/local/nginx/conf/nginx.conf.bak
# 配置 nginx.conf
sudo vim /usr/local/nginx/conf/nginx.conf

参考文档链接

worker_processes  auto;
events {worker_connections  1024;
}# RTMP configuration
rtmp {server {listen 1935; # Listen on standard RTMP portchunk_size 4000;application show {live on;# Turn on HLShls on;# Make sure Pernission of Nginx to writehls_path /mnt/hls/;hls_fragment 3;hls_playlist_length 60;# disable consuming the stream from nginx as rtmpallow play all;}}
}http {sendfile off;tcp_nopush on;aio on;directio 512;default_type application/octet-stream;server {listen 8080;#server_name ***.***.***.***;location / {# Disable cacheadd_header 'Cache-Control' 'no-cache';# CORS setupadd_header 'Access-Control-Allow-Origin' '*' always;add_header 'Access-Control-Expose-Headers' 'Content-Length';# allow CORS preflight requestsif ($request_method = 'OPTIONS') {add_header 'Access-Control-Allow-Origin' '*';add_header 'Access-Control-Max-Age' 1728000;add_header 'Content-Type' 'text/plain charset=UTF-8';add_header 'Content-Length' 0;return 204;}types {application/dash+xml mpd;application/vnd.apple.mpegurl m3u8;video/mp2t ts;}root /mnt/;}}
}

三、启动 Nginx 服务

方式一

安装nginx初始化脚本、获取nginx初始化脚本

wget https://raw.github.com/JasonGiedymin/nginx-init-ubuntu/master/nginx
sudo cp nginx /etc/init.d/
sudo chmod +x /etc/init.d/nginx
sudo update-rc.d nginx defaultssudo service nginx start
sudo service nginx stop

方式二

直接调用

# 开启
sudo /usr/local/nginx/sbin/nginx
# 关闭
sudo /usr/local/nginx/sbin/nginx -s stop

四、使用 RTMP 将视频推送到 Nginx

安装FFmpeg

sudo apt-get install ffmpeg

捕获网络摄像头 /dev/video0 并将其流式传输到 Nginx

ffmpeg -re -f video4linux2 -i /dev/video0 -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -f flv rtmp://localhost/show/stream

流式传输文件示例视频.mp4

ffmpeg -re -i example.mp4 -vcodec libx264 -vprofile baseline -g 30 -acodec aac -strict -2 -f flv rtmp://localhost/show/stream

流式传输另一个 rtmp 流

ffmpeg -i rtmp://example.com/appname/streamname -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -f flv rtmp://localhost/show/stream

浏览器获取视频流

http://localhost:8080/hls/stream.m3u8

补充

OBS 推流

检查 .m3u8 文件
