第一个dshow的playerdemo

　　书上的源码是：

　　[cpp]

　　#include

　　#include

　　using namespace std;

　　int main()

　　{

　　cout<<"PlayerDemo"<

　　IGraphBuilder * pGraph = NULL;

　　IMediaControl * pControl = NULL;

　　IMediaEvent * pEvent = NULL;

　　HRESULT hr = CoInitialize(NULL);

　　if (FAILED(hr))

　　{

　　printf("ERROR - Could not initialize COM library");

　　return 0;

　　}

　　hr = CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC_SERVER,

　　IID_IGraphBuilder, (void**)&pGraph);

　　if (FAILED(hr))

　　{

　　printf("ERROR - Could not create the Filter Graph Manager.");

　　return 0;

　　}

　　hr = pGraph->QueryInterface(IID_IMediaControl, (void**)&pControl);

　　hr = pGraph->QueryInterface(IID_IMediaEvent, (void**)&pEvent);

　　hr = pGraph->RenderFile(L"C:\\DXSDK\\Samples\\Media\\CLOCKTXT.avi", NULL);

　　if (SUCCEEDED(hr))

　　{

　　hr = pControl->Run();

　　if (SUCCEEDED(hr))

　　{

　　long evCode;

　　pEvent->WaitForCompletion(INFINITE, &evCode);

　　}

　　}

　　pControl->Release();

　　pEvent->Release();

　　pGraph->Release();

　　CoUninitialize();

　　return 0;

　　}

　　linker->input 里面包含Strmbasd.lib库。
