需求
本文介绍的是利用nginx和ffmpeg搭建流媒体服务器的过程。例如这种场景:公司内部需要同时观看在线直播时,如果每个人直接观看必然给出口带宽带来压力,影响正常访问外网的同事。所以可以在内网通过nginx+ffmpeg拉一路直播流,然后内网的用户访问内网的这台流媒体服务器即可。通过nginx+ffmpeg还可以实现推流、拉流、转推甚至利用FFmpeg实时切片、视频处理等,实现一套直播服务模型。
环境
系统环境:CentOS release 6.7 (Final)
步骤
安装ffmpeg
安装过程参考官方文档:https://trac.ffmpeg.org/wiki/CompilationGuide
安装Nginx
这里采用了编译安装的方式,需要注意的是:一定要添加nginx-rtmp-module模块
git clone https://github.com/arut/nginx-rtmp-module.git#编译的时候添加nginx-rtmp-module模块--add-module=path_of_/nginx-rtmp-module
我的nginx编译参数
./configure --prefix=/opt/nginx --user=nginx --group=nginx --with-http_ssl_module --with-http_gzip_static_module --with-http_stub_status_module --with-pcre=/opt/software/pcre-8.35 --with-zlib=/opt/software/zlib-1.2.8 --with-openssl=/opt/software/openssl-1.0.1i --add-module=/opt/software/nginx-1.8.1/modules/nginx-rtmp-module
修改nginx配置文件nginx.conf
