MATLAB调用rtsp,C++ RTSP/RTP流媒体客户端源码

以下是MATLAB调用rtsp的示例代码：

url = 'rtsp://username:password@ip_address:port/path'; % RTSP URL
vidObj = VideoReader(url); % 创建VideoReader对象
while hasFrame(vidObj)
   img = readFrame(vidObj); % 读取视频帧
   imshow(img); % 显示视频帧
end

对于C++ RTSP/RTP流媒体客户端，可以使用开源的Live555库。以下是示例代码：

#include <liveMedia.hh>
#include <BasicUsageEnvironment.hh>
#include <stdio.h>

int main(int argc, char** argv) {
  TaskScheduler* scheduler = BasicTaskScheduler::createNew();
  UsageEnvironment* env = BasicUsageEnvironment::createNew(*scheduler);

  RTSPClient* rtspClient = RTSPClient::createNew(*env, "rtsp://username:password@ip_address:port/path", 0, "username:password");
  if (rtspClient == NULL) {
    fprintf(stderr, "Failed to create RTSP client\n");
    exit(1);
  }

  RTSPStream* rtspStream = rtspClient->streamingOverTCP() ? (RTSPStream*)new TCPStreamSink(*env) : (RTSPStream*)new UDPStreamSink(*env);
  if (rtspStream == NULL) {
    fprintf(stderr, "Failed to create RTSP stream\n");
    exit(1);
  }

  rtspClient->sendDescribeCommand(continueAfterDESCRIBE, rtspStream);
  env->taskScheduler().doEventLoop(); // 进入事件循环

  Medium::close(rtspStream);
  Medium::close(rtspClient);
  env->reclaim();
  delete scheduler;

  return 0;
}

void continueAfterDESCRIBE(RTSPClient* rtspClient, int resultCode, char* resultString) {
  if (resultCode == 0) {
    rtspClient->sendSetupCommand(continueAfterSETUP, False, False);
  } else {
    fprintf(stderr, "Failed to send DESCRIBE command: %s\n", resultString);
    exit(1);
  }
}

void continueAfterSETUP(RTSPClient* rtspClient, int resultCode, char* resultString) {
  if (resultCode == 0) {
    rtspClient->sendPlayCommand(continueAfterPLAY);
  } else {
    fprintf(stderr, "Failed to send SETUP command: %s\n", resultString);
    exit(1);
  }
}

void continueAfterPLAY(RTSPClient* rtspClient, int resultCode, char* resultString) {
  if (resultCode != 0) {
    fprintf(stderr, "Failed to send PLAY command: %s\n", resultString);
    exit(1);
  }
}

需要注意的是，在使用Live555库时需要将其编译后才能使用。具体编译方法可以参考官方文档。
