第一个dshow的playerdemo

 

[cpp]  

#include <iostream>  

#include <dshow.h>  

using namespace std;  

  

int main()  

{  

    cout<<"PlayerDemo"<<endl;  

  

    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->QueryInte易做图ce(IID_IMediaControl, (void**)&pControl);  

    hr = pGraph->QueryInte易做图ce(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。
