一些MFC,VS2008及DirectShow的小技巧

註冊DLL檔的方法:

regsvr32 //註冊動態連結檔
regsvr32 -u //解除動態連結檔

[錯誤訊息] 正在停用的啟用內容不是最近啟動的那一個
0xC015000F: The activation context being deactivated is not the most recently activated one.

程式碼中加入

CWinApp::InitInstance();
afxAmbientActCtx = FALSE;

[警告訊息] 二進位碼不是以偵錯資訊而建置

專案屬性 -> 組態屬性 -> C/C++ ->最佳化 -> 停用
專案屬性 -> 組態屬性 -> 連結器 -> 命令列 -> 輸入 /debug

[DirectShow] 控制MPEG-2 Demultiplexer Filter的Pin

IMpeg2Demultiplexer *pDemux = NULL;

hr = m_pDemux->QueryInterface(IID_IMpeg2Demultiplexer, (void**)&pDemux);
GRAPH_LOG(gcMsgLog.LogToFile("QueryInterface()= %x",hr));


if (SUCCEEDED(hr))
{
        pDemux->DeleteOutputPin(L"004"); //刪除Pin腳

        // Define the media type.
        AM_MEDIA_TYPE mt;
        ZeroMemory(&mt, sizeof(AM_MEDIA_TYPE));
        mt.majortype = MEDIATYPE_Audio;
        mt.subtype = MEDIASUBTYPE_MPEG2_AUDIO;
        mt.formattype = FORMAT_WaveFormatEx;

        // Create a new output pin.
        IPin *pPin;

        hr = pDemux->CreateOutputPin(&mt, L"PSI Pin", &pPin);
 GRAPH_LOG(gcMsgLog.LogToFile("CreatOutputPin()= %x",hr));
 if (SUCCEEDED(hr))
 {
                // Map the PID.
  IMPEG2PIDMap *pPidMap = NULL;
  hr = pPin->QueryInterface(IID_IMPEG2PIDMap, (void**)&pPidMap);
  if (SUCCEEDED(hr))
  {
  
   ULONG cPid = 1;
   ULONG Pid[] = {0x00} ; // Map any desired PIDs.
   hr = pPidMap->MapPID(cPid, Pid, MEDIA_MPEG2_PSI);
   //pPidMap->Release();
  }else
   GRAPH_LOG(gcMsgLog.LogToFile("QueryTinterface__()=%x",hr));
  //pPin->Release();
 }
