TCC89播放代码与 LOG 对应

阅读与测试 Telechips 平台下音频播放 Filter，同时对比 WinCE 下标准的 Overlay 音频播放过程。了解音频播放过程，记录如下：

(1) CheckCoCreateInstance(hr, CLSID_FilterGraph, IID_IGraphBuilder, (void **)&mpGraph, TEXT("CLSID_FilterGraph fail")); 
  原型: BOOL CFilterControl::CheckCoCreateInstance(HRESULT &hr, REFCLSID rclsid, REFIID riid, LPVOID* ppv, LPCTSTR pszErrorMessage)
  调用 CoCreateInstance 的代码 : hr = ::CoCreateInstance(rclsid, NULL, CLSCTX_INPROC_SERVER, riid, ppv);
加载模块: quartz.dll
加载模块: mmtimer.dll
加载模块: waveapic.dll

(2) hr = CoCreateInstance((REFCLSID)CLSID_AudioRender, NULL, CLSCTX_INPROC, (REFIID)IID_IBaseFilter, (void **)&m_pAudioRenderFilter);
    hr = mpGraph->AddFilter(m_pAudioRenderFilter,L"Audio Renderer");
    
    hr = mpGraph->AddFilter(m_pAudioOutputControlFilter,L"TCC Audio Output Control Filter");
加载模块: TCCAudioOutputControlFilter.dll
对应实现: TWS893x_200\Filters\TCCAudioOutputControlFilter\TCCAudioOutputControlFilter.cpp
  CFactoryTemplate g_Templates[] = 
  {
    {
      L"TCC Audio Output Control Filter",
      &CLSID_TCCAudioOutputControlFilter,
      CAudioOutputControlFilter::CreateInstance,      // Create a new instance of this class
      NULL,
      &sudTCCAudioOutputControlFilter
    },
  };

(3) hr = CoCreateInstance((REFCLSID)CLSID_TCCDEQ, NULL, CLSCTX_INPROC, (REFIID)IID_IBaseFilter, (void **)&m_pDEQFilter);
    // DEQ Filter Add
    if(SUCCEEDED(hr))
      hr = mpGraph->AddFilter(m_pDEQFilter,L"TCC DEQ Filter");
加载模块: TCCDEQFilter.dll

(4) hr = mpGraph->RenderFile(FileName,NULL);
