1. 安装ffmpeg

   #安装h264视频编解码库
   sudo apt-get update
   sudo apt-get install libx264-dev
   
   #安装ffmpeg
   #通过源安装>>>>>>>>
   sudo add-apt-repository ppa:djcj/hybrid #添加源
   sudo apt-get update
   sudo apt-get install ffmpeg
   sudo ffmpeg -version #验证是否安装成功
   #源码安装>>>>>>>>
   wget http://ffmpeg.org/releases/ffmpeg-3.0.9.tar.bz2
   sudo tar jxvf ffmpeg-3.0.9.tar.bz2
   cd ffmpeg-3.0.9/
   sudo ./configure --enable-shared --enable-pthreads --enable-gpl  --enable-avresample $ --enable-libx264 --enable-libtheora  --disable-yasm
   sudo make   
   sudo make install
   

2. 安装nginx

   #源码安装>>>>>>>>
   #安装依赖
   sudo apt-get install build-essential
   sudo apt-get install libtool
   sudo apt-get update
   sudo apt-get install libpcre3 libpcre3-dev
   sudo apt-get install zlib1g-dev
   sudo apt-get install openssl
   #安装
   sudo mkdir nginx
   cd nginx
   git clone https://github.com/arut/nginx-rtmp-module.git
   sudo wget http://nginx.org/download/nginx-1.12.0.tar.gz
   sudo tar -zxvf nginx-1.12.0.tar.gz
   cd nginx-1.12.0/
   sudo ./configure --prefix=/usr/local/nginx --with-http_ssl_module --add-module=../nginx-rtmp-module
   sudo make
   sudo make install
   #启动：
   sudo /usr/local/nginx/sbin/nginx
   #or
   sudo /usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf
   

3. 配置Nginx流媒体服务器

   #停止
   sudo /usr/local/nginx/sbin/nginx -s stop 
   sudo vim /usr/local/nginx/conf/nginx.conf
   #添加
   rtmp {
       server {
               listen 1935;
               chunk_size 4096;
   
               application live {
                       live on;
                       record on;
                       }
       }
   }
   #重新启动
   sudo /usr/local/nginx/sbin/nginx
   

4. ffmpeg 推流

   ffmpeg -re -i /home/test.mp4 -vcodec copy -acodec copy -b:v 800k -b:a 32k -f flv rtmp://localhost/live
   

5. 客户端拉流

   使用vlc打开网络串流,输入流媒体服务器地址:rtmp://服务器IP:1935/live/ ,即可播放

nginx的删除

$ sudo service nginx stop
$ sudo apt-get --purge remove nginx
$ sudo apt-get autoremove
$ dpkg --get-selections|grep nginx
#结果:nginx-common
$ sudo apt-get --purge remove nginx-common
