ffmpeg rtsp转flv挂载到web端（Linux版）

ffmpeg rtsp转flv挂载到web端（Linux版）

1. 下载ffmpeg

解压目录

Linux安装nginx集成nginx-http-flv-module

Linux安装nginx运行环境

• 安装gcc-c++编译器

  yum install gcc-c++
  yum install -y openssl openssl-devel
  

• 安装pcre，zlib包

  yum install -y pcre pcre-devel
  yum install -y zlib zlib-devel
  

下载安装nginx和nginx-http-flv-module

• 下载安装包nginx，nginx-http-flv-module

  Nginx

  nginx-http-flv-module

• 新建目录/usr/local/mysoft,将下载好的压缩包放到mysoft目录下

• 解压nginx

  tar -zxvf nginx-1.18.0.tar.gz
  cd nginx-1.18.0
  

• 执行命令将nginx-http-flv-module模块添加到nginx执行安装

  ./configure --add-module=/usr/local/mysoft/nginx-http-flv-module --with-http_ssl_module
  make && make install
  

• nginx会被安装到/usr/local/nginx目录下

• 配置nginx.conf
