live555 實作一個最簡單的RTSP伺服器及其makefile

myser.cpp 和makefile 放在live\mediaServer檔案夾中

myser.cpp

#include <BasicUsageEnvironment.hh>

#include "liveMedia.hh"

static ServerMediaSession* createNewSMS(UsageEnvironment& env, char const* fileName);

int main()

{

    TaskScheduler* scheduler;

    UsageEnvironment* env ;

    RTSPServer* rtspServer;

    ServerMediaSession* sms;

    //建立任務調用器

    scheduler = BasicTaskScheduler::createNew();

    //建立互動環境

    env = BasicUsageEnvironment::createNew(*scheduler);

    //建立RTSP伺服器

    rtspServer = RTSPServer::createNew(*env,554);    //使用554端口

    if(rtspServer == NULL)

    {

        rtspServer = RTSPServer::createNew(*env,8554);   //554端口被占用，就使用8554端口

    }

    //列印伺服器位址

    *env << "Play streams from this server using the URL\n\t"

         << rtspServer->rtspURLPrefix() << "<filename>.\n";

    //建立session

    sms = createNewSMS(*env, "test.mpg");

    rtspServer->addServerMediaSession(sms);

    //添加其它檔案對應的session...

    //進行事件循環

    env->taskScheduler().doEventLoop(); // does not return

    return 0;

}

static ServerMediaSession* createNewSMS(UsageEnvironment& env, char const* fileName)

{

    char const* extension = strrchr(fileName, '.');

    ServerMediaSession* sms = NULL;

    Boolean reuseSource = False;    //不重用source

    sms = ServerMediaSession::createNew(env, fileName);  //建立一個session

    //

    //在session中添加subssesion

    //

    if(strcmp(extension, ".aac") == 0)

    {

        sms->addSubsession(ADTSAudioFileServerMediaSubsession::createNew(env, fileName, reuseSource));

    }

    else if(strcmp(extension, ".264") == 0)

    {

        sms->addSubsession(H264VideoFileServerMediaSubsession::createNew(env, fileName, reuseSource));

    }

    else if(strcmp(extension, ".mpg") == 0)
