示例1: GetCreateVideoAcceleratorData

STDMETHODIMP CVideoDecOutputPin::GetCreateVideoAcceleratorData(const GUID *pGuid, LPDWORD pdwSizeMiscData, LPVOID *ppMiscData)
{
	HRESULT								hr						= E_UNEXPECTED;
	AMVAUncompDataInfo					UncompInfo;
	AMVACompBufferInfo					CompInfo[30];
	DWORD								dwNumTypesCompBuffers	= countof(CompInfo);
	CComQIPtr<IAMVideoAccelerator>		pAMVideoAccelerator		= GetConnected();
	DXVA_ConnectMode*					pConnectMode;

	if (pAMVideoAccelerator) {
		memcpy (&UncompInfo.ddUncompPixelFormat, &m_ddUncompPixelFormat, sizeof (DDPIXELFORMAT));
		UncompInfo.dwUncompWidth		= m_pVideoDecFilter->PictWidthRounded();
		UncompInfo.dwUncompHeight		= m_pVideoDecFilter->PictHeightRounded();
		hr = pAMVideoAccelerator->GetCompBufferInfo(&m_GuidDecoderDXVA1, &UncompInfo, &dwNumTypesCompBuffers, CompInfo);

		if (SUCCEEDED (hr)) {
			hr = m_pVideoDecFilter->CreateDXVA1Decoder (pAMVideoAccelerator, pGuid, m_dwDXVA1SurfaceCount);

			if (SUCCEEDED (hr)) {
				m_pVideoDecFilter->SetDXVA1Params (&m_GuidDecoderDXVA1, &m_ddUncompPixelFormat);

				pConnectMode					= (DXVA_ConnectMode*)CoTaskMemAlloc (sizeof(DXVA_ConnectMode));
				pConnectMode->guidMode			= m_GuidDecoderDXVA1;
				pConnectMode->wRestrictedMode	= m_pVideoDecFilter->GetDXVA1RestrictedMode();
				*pdwSizeMiscData				= sizeof(DXVA_ConnectMode);
				*ppMiscData						= pConnectMode;
			}
		}
