live555实现H264实时流进行RTSP发送

liveMedia 项目(http://www.live555.com/)的源代码包括四个基本的库，各种测试代码以及Media Server。四个基本的库分别是: UsageEnvironment&TaskScheduler, groupsock, liveMedia和BasicUsageEnvironment。UsageEnvironment 和TaskScheduler 类用于事件的调度，实现异步读取事件的句柄的设置以及错误信息的输出。另外，还有一个HashTable 类定义了一个通用的hash 表，其它代码要用到这个表。这些都是抽象类，在应用程序中基于这些类来实现自己的子类。groups

#include “H264framedLiveSource.hh“
