nginx+rtmp服务器+ffmeg推流+ffpaly播放

简单的直播搭建流程

本微博在借鉴其他大牛之后，觉得应该写一个直播的完整流程，虽然简单，但是会有一个宏观感受：

• 搭建nginx服务器
  工具：
  nginx下载地址：https://nginx.org/download/nginx-1.13.6.zip
  nginx-rtmp-module-master.zip下载地址：https://github.com/arut/nginx-rtmp-module/

使用方法：
将两个工具文件解压，然后将这个nginx-rtmp-module-master放到nginx解压文件的一级目录底下

配置文件conf\nginx-win-rtmp.conf的方法：
见http://blog.csdn.net/fireroll/article/details/51985688
#user nobody;
# multiple workers works !
worker_processes 2;

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

events {
worker_connections 8192;
# max value 32768, nginx recycling connections+registry optimization =
# this.value * 20 = max concurrent connections currently tested with one worker
# C1000K should be possible depending there is enough ram/cpu power
# multi_accept on;
}

rtmp {
server {
listen 1935;
chunk_size 4000;
application live {
live on;
}
}
}

}

• 启动服务器
  进入windows的cmd;
  cd nginx-1.7.11.3-Gryphon
  nginx.exe -c conf\nginx-win-rtmp.conf

• 验证是否配置成功
  打开浏览器，输入localhost，如果出现
  
  表示连接成功

• 使用ffmpeg推流
  使用的资源为mp4，命名为test.mp4（本人处理时，为了方便，将视频文件放到ffmpeg目录底下）
  进入win cmd，cd到ffmpeg目录，如果不是管理员，可使用如下形式：
  （cd +/d +路径）的方式进入，然后输入命令：
  ffmpeg -re -i localFile.mp4 -c copy -f flv rtmp://localhost/live/streamName
  注意：直接推mp4流失败，得先remux成flv（毕竟flv和rtmp都是Adobe公司的，配套使用）

• 使用ffplay拉流
  ffplay rtmp://localhost/live/streamName

• 结论
  这样就可以完成一个简单的直播流程了
