利用Nginx搭建http和rtmp协议的流媒体服务器

实验目的:让Nginx支持flv和mp4格式文件，同时支持Rtmp协议；同时打开rtmp的hls功能

 资料:
 HTTP Live Streaming（缩写是 HLS）是一个由苹果公司提出的基于HTTP的流媒体 网络传输协议。
 HLS只请求基本的HTTP报文，与实时传输协议（RTP)不同，HLS可以穿过任何允许HTTP数据通过的防火墙或者代理服务器。它也很容易使用内容分发网络来传输媒体流。
 使用ffmpeg来完成对flv、mp4、mp3等格式的转化（点播实验暂时不测试）
 
一、准备工作
 模块:nginx_mod_h264_streaming(支持h264编码的视频)
 模块:http_flv_module 支持flv
 模块:http_mp4_module 支持mp4
