现在搭一个环境测试一下

多次点播不出图像的问题

刚收到数据的时候写下了文件

       FILE * output1 = fopen("D:\\amplesky\\software_ps\\web\\log\\OUT1.mp4", "w+b");
       if (output1 != NULL)
       {
        fwrite(&pTmpBuffer[hdr],sizeof(char),1,output1);
       }
       
       只针对单个源的测试
       
       
        if(lpReqTCP->iStreamType == STREAM_VIDEO)
     {
      bool needIframe =false;
      this0->m_iFrameNum = 0;
      if(!this0->OpenDeviceChannel(lpReqTCP->iChannel - 1))
      {
       needIframe = true;
       AMP_STRU_REPLY_TCP_PREVIEW_EX sReplyTCP;
       memset(&sReplyTCP, 0, sizeof(AMP_STRU_REPLY_TCP_PREVIEW_EX));
       sReplyTCP.iErrorCode = AMP_NETSDK_NOERROR;
       memcpy(&(sReplyTCP.sHeader), &(this0->m_channel[lpReqTCP->iChannel-1].m_sHeader), sizeof(TSTREAM_HEADER));

       char tmp[512];
       sprintf(tmp,"AMP_REPLY_TCP_PREVIEW already open  recv tickcount %d \n",GetTickCount());
       AMP_PS_DEBUG(tmp);

       SendMessageToDevice(acceptsocket, AMP_REPLY_TCP_PREVIEW, sizeof(AMP_STRU_REPLY_TCP_PREVIEW_EX), &sReplyTCP);
       EnterCriticalSection(&this0->m_channel[lpReqTCP->iChannel-1].m_csVideoSocket);
       this0->m_channel[lpReqTCP->iChannel-1].m_setVideoSendSocket.insert(acceptsocket);
       LeaveCriticalSection(&this0->m_channel[lpReqTCP->iChannel-1].m_csVideoSocket);
      }
      //现在测试一下
      //EnterCriticalSection(&this0->m_channel[lpReqTCP->iChannel-1].m_csVideoSocket);
      //this0->m_channel[lpReqTCP->iChannel-1].m_setVideoSendSocket.insert(acceptsocket);
      //LeaveCriticalSection(&this0->m_channel[lpReqTCP->iChannel-1].m_csVideoSocket);
      if (needIframe)
      {
                            this0->m_needIframe  = true;
      }
     }
     else
     {
      AMP_STRU_REPLY_TCP_PREVIEW sReplyTCP;
      memset(&sReplyTCP, 0, sizeof(AMP_STRU_REPLY_TCP_PREVIEW));
      sReplyTCP.iErrorCode = AMP_NETSDK_NOERROR;
      SendMessageToDevice(acceptsocket, AMP_REPLY_TCP_PREVIEW, sizeof(AMP_STRU_REPLY_TCP_PREVIEW), &sReplyTCP);
      EnterCriticalSection(&this0->m_channel[lpReqTCP->iChannel-1].m_csAudioSocket);
      this0->m_channel[lpReqTCP->iChannel-1].m_setAudioSendSocket.insert(acceptsocket);
      LeaveCriticalSection(&this0->m_channel[lpReqTCP->iChannel-1].m_csAudioSocket);
     }
     
     只有视频才会向3G设备请求
     
     OpenDeviceChannel
     
      只是在没有对讲且没有视频socket的时候，才会向3G设备请求
     
      CloseDeviceChannel
     
        也就是说打开和关闭都是在没有视频socket的情况下才会进行
       
        那么在什么情况下调用呢？
       
        对方是怎么关闭的？
       
        打开是直接建立socket thread 在各自socket上发送请求
       
        关闭是直接关闭socket，线程退出  在命令通道上发送关闭请求
       
        对这边有影响么？
       
        设备回应
       
        LPAMP_STRU_REPLY_TCP_PREVIEW_EX lpReplyTCP = (LPAMP_STRU_REPLY_TCP_PREVIEW_EX)lpPDU->iMessageBody;
     this0->SendMessageToNETSDK(acceptsocket, AMP_REPLY_TCP_PREVIEW, sizeof(AMP_STRU_REPLY_TCP_PREVIEW_EX), lpReplyTCP);
     if(ntohl(lpReplyTCP->iErrorCode == AMP_PROXY_NOERROR))
     {
      this0->SetStreamHeader(acceptsocket, ntohl(lpReplyTCP->iChannel) - 1, &(lpReplyTCP->sHeader));
     }
     
     设备回应 相当重要的一个东西就是编码头了
              
  m_mapSocketInfo 存放了所有的接受socket
  
 并且存放了所有的socket上存放的信息类型
     
 bool bRet = false;
 EnterCriticalSection(&m_csLockSocket);
 std::map<SOCKET, int>::iterator iterSocket = m_mapSocketInfo.begin();
 while (iterSocket != m_mapSocketInfo.end())
 {

  if(iMessType == iterSocket->second + 1)
  {
  // AMP_PS_DEBUG("SendMessageToDevice\n");
   SendMessageToDevice(iterSocket->first, iMessType, uiMessLen, pMessBody);

#ifdef _DEBUG
   char tmp[512];
   sprintf(tmp,"op = %d, last op = %d\n", iMessType, iterSocket->second);
   AMP_PS_DEBUG(tmp);
#endif
   if (iMessType == AMP_REPLY_TCP_PREVIEW) 
   {

#ifdef _DEBUG
    char tmp[512];
    sprintf(tmp,"AMP_REPLY_TCP_PREVIEW op = %d, last op = %d\n", iMessType, iterSocket->second);
    AMP_PS_DEBUG(tmp);
#endif
    EnterCriticalSection(&m_channel[0].m_csVideoSocket);
    m_channel[0].m_setVideoSendSocket.insert(iterSocket->first);
    LeaveCriticalSection(&m_channel[0].m_csVideoSocket);
   }
   iterSocket->second = iMessType;
   bRet = true;
   break;
  }
  iterSocket++;
 }
 LeaveCriticalSection(&m_csLockSocket);
