[RTMP]Flash P2P应用AS3源代码示例
经过两天两夜的艰苦努力,史上第一个Flash P2P源代码终于被我老虫搞出来啦!
再来看使用方法:
在A、B两台具有静态IP的机器上打开本页后,程序首先生成一个随机的用户名myName并自动连接到Adobe官方的stratus服务器,连接成功后,程序会自动获取一个myID号。将A中的myName和myID复制粘贴到B中的oppName和oppID中,单击B中的Call按钮呼叫A,当A中有呼叫的提示信息时,在A中单击Accept按钮,这样P2P连接就建立了!P2P连接建立后,可以播放对方视频,可以进行文本聊天。
通过该示例你可以:
1、了解如何使用新的RTMFP协议连接到远程服务器。
2、了解如何建立P2P连接。
3、了解如何发布和接收P2P流。
4、了解如何进行文本聊天。
已知问题:
1、(后经测试,是可以在广域网使用的!)。
2、在进行P2P呼叫的时候速度慢,即使是在同一个局域网内。
SWF文件在下面,你可以将它另存到桌面上使用,要注意允许SWF访问网络及相关的安全设置:
