http直播（RTMP+ffmpeg）平台简单搭建笔记

直播平台大致流程

该图片转自其他网络

实时传输协议有：RTMP、HLS、HDL（HTTP-FLV）

编译环境

apt-get install build-essential

nginx安装

 安装pcre（目前最新8.44）

./configure
make && make install

pcre-config --version //查看版本

下载nginx-rtmp-module源

git 下载https://github.com/arut/nginx-rtmp-module

安装nginx（目前最新1.17.9）

./configure --add-module=../nginx-rtmp-module --prefix=/usr/local/nginx --with-http_stub_status_module --with-http_ssl_module --with-pcre=/usr/local/pcre-8.44

make

make install

启动nginx

./sbin/nginx -c /usr/local/nginx/conf/nginx.conf

obs studio视频直播录制软件安装（debian尽量9以上，因为ops有要求，不然自己编译有点麻烦）

https://obsproject.com/download

ffmpeg转码安装

https://obsproject.com/wiki/install-instructions#linux里有安装流程

或者低版本的

sh -c 'echo "deb http://www.deb-multimedia.org jessie main" >> /etc/apt/sources.list'

apt-get update

apt-get install deb-multimedia-keyring

apt-get install ffmpeg

rtmp参数配置

nginx.conf点播配置

 
#播放地址示例: rtmp://localhost/live/qq.mp4 
rtmp { #RTMP服务
 server {
 listen 1935; #//服务端口
 chunk_size 4096; #//数据传输块的大小
 application live {
 play /usr/local/nginx/video; #//视频文件存放位置。
 }
}
}

nginx.conf直播配置

worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

        }


     application hls {
            live on;        #直播

             #回看功能 视频切片变成ts文件
            hls on;                                 #这个参数把直播服务器改造成实时回放服务器。
            wait_key on;                           #对视频切片进行保护，这样就不会产生马赛克了。
            hls_path /usr/local/nginx/video/hls;       #切片视频文件存放位置。
            hls_fragment 10s;                       #每个视频切片的时长。
            hls_playlist_length 120;                #总共可以回看的事件，这里设置的是1分钟。
            hls_continuous on;                      #连续模式。
            #hls_cleanup on;                         #对多余的切片进行删除。
            #hls_nested on;                          #嵌套模式。

重启nginx

sudo ./sbin/nginx -s reload

开启 ffmpeg

ffmpeg -re -i /usr/local/nginx/video/test.mp4 -vcodec libx264 -vprofile baseline -acodec aac -strict -2 -f flv rtmp://localhost/hls/stream

结果

http直接播放
