快速构建简单的流媒体服务概述系统配置RTMP协议概述Red5概述Red5服务构建
前言
最近自己在研究流媒体播放的相关技术，但是网上的资料很少。 在查阅开源精神和资料的各位的帮助下，把自己的心得记录下来，便于共享和今后的维护。
在此强烈感谢并推荐雷神(懦弱的气氛)

系统要构成完整的流媒体系统，需要三个部分：编码器、流媒体服务器和播放器。
编码器对MP3文件和麦克风输入等内容源进行编码，并将编码的内容发送到流式服务器。流式服务器向互联网公开，客户端播放器连接到流式服务器即可
这次构建过程是基于RTMP协议进行的。
RTMP协议概述
播放RTMP协议的流媒体需要经过握手、建立连接、建立流和播放几个步骤。
rmp连接从握手开始。
1 )连接建立阶段用于在客户端和服务器之间建立“网络连接”；2 )流建立阶段用于在客户端和服务器之间建立“网络流”；3 )播放阶段是视频数据Red5概述Red5是一台使用Java开发开源的Flash流媒体服务器。 开源使软件更容易扩展，下载后可以修改源代码更经济，与FMS的昂贵费用相比，Red5可以为常见的APP应用程序节省大量费用，同时服务器端面向Java对象的语言为fmms 考虑到Red5的各种好处，它在推出后不久就被很多用户接受了。
Red 5支持：
将音频(MP3 )和视频(FLV、F4V、MP4、3gp )转换为播放流
录制客户端的播放流，将摄像机、麦克风等发送的音视频录制保存到服务器中
共享对象；
现场流分发
远程呼叫；
协议：RTMP、RTMPT、RTMPS和and RTMPE。
Red5服务器构建并自行安装JDK本文不进行演示

下载Red5:(本人使用版本：1.0.10 )。
官网： http://red5.org/
github:https://github.com/red5/red5-server/releases
下载并解压缩到自己的固定文件夹中。 图：
或者，可以在conf/red5.properties文件下更改IP和端口号
