VC6.0下DirectShow开发环境配置

1 下载SDK：DirectX9.0b (要含有directshow的DirectX) 然后安装

2 编译
打开<SDK root>/Samples/C++/DirectShow/BaseClasses/baseclasses.dsp，degug编译得到Strmbasd.lib。release 编译得到strmbase.lib。

3 添加inlude和lib信息（Tools->Options->Directories ）
Include - 添加<SDK root>/Include
-添加<SDK root>/SAMPLES/C++/DIRECTSHOW/BASECLASSES[注1]

Lib - 添加<SDK root>/Lib
- <SDK root>/SAMPLES/C++/DirectShow/BASECLASSES/DEBUG

4 在Project->Setting->Link 中添加Strmbasd.lib 注[2]

[注1]：此处添加streams.h所在路径，路径可能有所不同
[注2]：步骤4缺，将导致
error LNK2001: unresolved external symbol _IID_IMediaEvent
error LNK2001: unresolved external symbol _IID_IMediaControl
error LNK2001: unresolved external symbol _CLSID_FilterGraph
error LNK2001: unresolved external symbol _IID_IGraphBuilder
Debug/Howtoplayafile.exe : fatal error LNK1120: 4 unresolved externals
Error executing link.exe.

测试代码：

void main(void)

{
IGraphBuilder *pGraph = NULL;

IMediaControl *pControl = NULL;

IMediaEvent   *pEvent = NULL;

// Initialize the COM library.

HRESULT hr = CoInitialize(NULL);

if (FAILED(hr))

{

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

return;

}

// Create the filter graph manager and query for interfaces.

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;

}

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

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

// Build the graph. IMPORTANT: Change this string to a file on your system.

//    hr = pGraph->RenderFile(L"C://Example.avi", NULL);

hr = pGraph->RenderFile(L"C://DXSDK//Samples//Media//chicken.wmv", NULL); // 打开一个媒体文件

if (SUCCEEDED(hr))

{

// Run the graph.

hr = pControl->Run();

if (SUCCEEDED(hr))

{

// Wait for completion.

long evCode;

pEvent->WaitForCompletion(INFINITE, &evCode);

// Note: Do not use INFINITE in a real application, because it

// can block indefinitely.

}

}

pControl->Release();

pEvent->Release();

pGraph->Release();

CoUninitialize();

}
