1.如何在VS2008中使用jrtplib

   在网友＠向左向右走的一篇文章中说的很详细，参见原文链接：　 http://blog.csdn.net/sunloverain2/archive/2010/03/20/5398694.aspx 

　我补充一点：在VS2008中，lib库和头文件可以不加到VS的安装目录下，可以拷贝到自己所建的工程目录下，并在Solution Explorer窗口      下，在你所建的工程名上“右击”，选择“Properties"-->"Configuration Properties"-->"C/C++"-->"General"-->

   "Addtional  Include Directory" 把包含所有头文件的文件夹添加进去；把jrtplib.lib，jthread.lib拷贝到.cpp的同一目录下，在程序中使       用#pragma comment(lib,"jrtplib.lib")  和 #pragma comment(lib,"jthread.lib")即可。

   lib库在VS2008中还有另一种加载方法，可以在网上找找。

2.使用jrtplib写的一个简单服务器程序代码：

   该程序是从 官方下载jrtplib文件时所带的example的基础上 修改得到，代码如下：//先打开服务器端，然后打开客户端<br /> #include "rtpsession.h"<br /> #include "rtpudpv4transmitter.h"<br /> #include "rtpipv4address.h"<br /> #include "rtpsessionparams.h"<br /> #include "rtperrors.h"<br /> #include "rtppacket.h"<br /> #ifndef WIN32<br /> #include <netinet/in.h><br /> #include <arpa/inet.h><br /> #else<br /> #include <winsock2.h><br /> #endif // WIN32<br /> #include <stdlib.h><br /> #include <stdio.h><br /> #include <iostream><br /> #include <string><br /> #pragma comment(lib,"jrtplib.lib")<br /> #pragma comment(lib,"jthread.lib")<br /> #pragma comment(lib,"ws2_32.lib")<br /> //<br /> // This function checks if there was a RTP error. If so, it displays an error<br /> // message and exists.<br /> //<br /> void checkerror(int rtperr)<br /> {<br /> if (rtperr < 0)<br /> {<br /> std::cout << "ERROR: " << RTPGetErrorString(rtperr) << std::endl;<br /> exit(-1);<br /> }<br /> }<br /> //<br /> // The main routine<br /> //<br /> int main(void)<br /> {<br /> #ifdef WIN32<br /> WSADATA dat;<br /> WSAStartup(MAKEWORD(2,2),&dat);<br /> #endif // WIN32</p> <p> RTPSession sess;<br /> uint16_t portbase,destport;<br /> uint32_t destip;<br /> std::string ipstr;<br /> int status,i(1);<br /> int packetlen(0);<br /> unsigned char *ptr;<br /> // First, we'll ask for the necessary information</p> <p>// std::cout << "Enter local portbase:" << std::endl;<br /> // std::cin >> portbase;<br /> // std::cout << std::endl;<br /> portbase = 6000;</p> <p> // Now, we'll create a RTP session, set the destination, send some<br /> // packets and poll for incoming data.</p> <p> RTPUDPv4TransmissionParams transparams;<br /> RTPSessionParams sessparams;</p> <p> // IMPORTANT: The local timestamp unit MUST be set, otherwise<br /> // RTCP Sender Report info will be calculated wrong<br /> // In this case, we'll be sending 10 samples each second, so we'll<br /> // put the timestamp unit to (1.0/10.0)<br /> sessparams.SetOwnTimestampUnit(1.0/10.0); </p> <p> sessparams.SetAcceptOwnPackets(true);<br /> transparams.SetPortbase(portbase);<br /> status = sess.Create(sessparams,&transparams);<br /> checkerror(status);</p> <p> RTPIPv4Address addr(destip,destport);</p> <p> status = sess.AddDestination(addr);<br /> checkerror(status);</p> <p> do{<br /> sess.BeginDataAccess();</p> <p> // check incoming packets<br /> if (sess.GotoFirstSourceWithData())<br /> {<br /> do<br /> {<br /> RTPPacket *pack;</p> <p> while ((pack = sess.GetNextPacket()) != NULL)<br /> {<br /> // You can examine the data here<br /> ptr = (unsigned char *)(pack->GetPayloadData());<br /> packetlen = pack->GetPayloadLength();<br /> printf("Got packet %d: ", i);<br /> ++i;<br /> for(int ix=0;ix<packetlen;++ix)<br /> printf("%c",*ptr++);<br /> printf("/n");</p> <p> // we don't longer need the packet, so<br /> // we'll delete it<br /> sess.DeletePacket(pack);<br /> }<br /> } while (sess.GotoNextSourceWithData());<br /> }</p> <p> sess.EndDataAccess();</p> <p>#ifndef RTP_SUPPORT_THREAD<br /> status = sess.Poll();<br /> checkerror(status);<br /> #endif // RTP_SUPPORT_THREAD</p> <p> RTPTime::Wait(RTPTime(1,0));<br /> }while(1);</p> <p> sess.BYEDestroy(RTPTime(10,0),0,0);<br /> #ifdef WIN32<br /> WSACleanup();<br /> #endif // WIN32<br /> return 0;<br /> }<br />
