nginx+rtmp服务器+ffmeg推流+ffpaly播放（支持rtmp和hls流两种）

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：

#    location / {
#        root   html;

}
如果需要支持HLS流：
则修改如下：
rtmp {
server {
listen 1935;
chunk_size 4000;
application hls { #rtmp推流请求路径
live on;
hls on;
hls_path C:\nginx\hls;
hls_fragment 5s;
}
}
}
说明：hls_path 为m3u8，及ts文件存储路径； hls_fragment为每个ts的时长

• 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
