流媒体文件是目前非常流行的网络媒体格式之一,这种文件允许用户一边下载一边播放,从而大大减少了用户等待播放的时间。另外通过网络播放流媒体文件时,文件本身不会在本地磁盘中存储,这样就节省了大量的磁盘空间开销。正是这些优点,使得流媒体文件被广泛应用于网络播放。
流媒体服务器是通过建立发布点来发布流媒体内容和管理用户连接的。流媒体服务器能够发布从视频采集卡或摄像机等设备中传来的实况流,也可以发布事先存储的流媒体文件,并且发布实况流和流媒体文件的结合体。一个媒体流可以由一个媒体文件构成,也可以由多个媒体文件组合而成,还可以由一个媒体文件目录组成。
Flash Media Server,简称 FMS,是 Flash 大家庭里的一员,被称为是目前开发 Web 音视频应用程序(比如,视频聊天室、视频会议系统、播客系统、音视频留言等等)的最方便最快捷的解决方案。也在 web 应用程序开发上有着越来越广泛的应用。当然 FMS 这种优良功能并不是免费提供给广大用户的,几千美金每个点的价格让很多开发人员望而却步。于是,大家开始尝试寻找一种更合适的解决方案,开源的 Red5 便成为了人们的新宠。
Red5 是一个采用 Java 开发的开源的 Flash 流媒体服务器,功能上与 FMS 类似。它支持:把音频(MP3)和视频(FLV)转换成播放流;录制客户端播放流(只支持 FLV);共享对象;现场直播流发布;远程调用。Red5 使用 RSTP 作为流媒体传输协议,包括在线录制,Flash 流媒体播放,在线聊天,视频会议等一些基本功能。国内外基于 Red5 的流媒体应用产品也在不断推广,例如在线视频会议 Openmeeting,大型 Flash 网游功夫之王 2。
Red5 是一个采用 Java 开发开源的 Flash 流媒体服务器。免费开源使软件更加容易扩展,下载后你可以对源代码进行修改;更加经济,比起 FMS 高昂的费用,Red5 能为一般的应用节约大笔费用;同时服务器端的 Java 面向对象语言比起 FMS 服务器端的 ActionScript2 语言更加成熟。鉴于 Red5 的种种优势,推出不久便被广大用户所接受。
Red 5 支持:
JDK自行安装 下载Red5
https://github.com/Red5/red5-server/releases
解压到自己的一个能记住的文件夹中 eg:F:\Red5
修改red5.properties配置文件..\conf\red5.properties
只需要配置HTTP 和RMTP节点的host和port即可 默认也行host配置成0.0.0.0 输入局域网IP或者127.0.0.1都可以正常访问
