1。简单地播放文件
#include <dshow.h>
#pragma comment (lib,"Ole32.lib")
#pragma comment (lib,"Strmiids.lib")
#define FILENAME L"C:\\Documents and Settings\\vs6\\桌面\\temp\\FL5007822001-500-2.avi"
bool g_bExit=false; //this APP will be exited when g_bExit=TURE
#define ture (bool)-1
int main()
{
IGraphBuilder *pGraphBuilder; //这是directshow的核心
IMediaControl *pMediaControl; //帮我们连接filter(媒体文件,解码器等)          //简单的说,它帮我们简单地打开和播放文件.
IVideoWindow *pVideoWindow; //用这个来控制directshow的视频窗口
//COM初始化
CoInitialize(NULL);

//建立FilterGraph
CoCreateInstance(CLSID_FilterGraph,NULL,CLSCTX_INPROC,IID_IGraphBuilder,
(LPVOID*)&pGraphBuilder);

// 向directshow询问MediaControl接口:
pGraphBuilder->QueryInterface(IID_IMediaControl,(LPVOID*)&pMediaControl);

//建立 Graph:
pMediaControl->RenderFile(FILENAME);

           //向directshow询问VideoWindow接口:
pGraphBuilder->QueryInterface(IID_IVideoWindow,(LPVOID*)&pVideoWindow);

// 全屏：
pVideoWindow->put_Visible(OATRUE);
pVideoWindow->put_FullScreenMode(OATRUE);

           //开始播放：
pMediaControl->Run();

// 等待：
MessageBox(NULL,"Block Execution","Block",MB_OK);
          
          //停止：
pMediaControl->Stop();
// release resource:
pVideoWindow->Release();
pMediaControl->Release();
pGraphBuilder->Release();

// COM 销毁:
CoUninitialize();

return 0;
}

2。在自己的window中循环播放。
接收到“播放结束”消息的时候，重新播放文件即可实现循环。
请建立Win32 App！

#include <dshow.h>
#include <windows.h>
#pragma comment (lib,"Ole32.lib")
#pragma comment (lib,"Strmiids.lib")

#define ture (bool)-1
//你应该替换这个文件名：
#define FILENAME L"C:\\Documents and Settings\\vs6\\桌面\\temp\\FL5007822001-500-2.avi"
#define WM_GRAPH_NOTIFY (WM_APP + 1) //g_pMediaEventEx的消息

bool g_bExit=false; //当g_bExit=TURE 时，程序结束
HWND g_hwnd=0; //我们的播放器的主窗口
IMediaEventEx *g_pMediaEventEx; //可以从directshow接受事件消息
//当媒体播放结束后，它会通知我们
IMediaControl *g_pMediaControl; //帮我们连接过滤器（文件，解码器。。。）             //简单地说，它帮我们简单的打开和播放文件
IMediaPosition *g_pMediaPosition; //用这个来取得/设置媒体播放的位置等。

void OnGraphNotify(); //当g_pMediaEventEx发消息通知我们时，我们就调用这个函数
LRESULT WINAPI WinProc(HWND hwnd,UINT msg,WPARAM wparam,LPARAM lparam);

int WINAPI WinMain(HINSTANCE hInst,HINSTANCE hPrevInst,LPSTR CmdLine,int nShowCmd)
{
IGraphBuilder *pGraphBuilder; //directshow的核心
IVideoWindow *pVideoWindow; //用这个来控制directshow的视频窗口

//COM初始化：

//向directshow询问MediaEventsEx接口:
pGraphBuilder->QueryInterface(IID_IMediaEventEx,(LPVOID*)&g_pMediaEventEx);

//这段代码是建立一个播放器主窗口并显示之：
WNDCLASSEX wc={sizeof(WNDCLASSEX),CS_CLASSDC,WinProc,0L,0L,
GetModuleHandle(0),0,0,0,0,"instemast",0};
RegisterClassEx(&wc);
//我们窗口的客户区坐标：

g_hwnd=CreateWindow("instemast","dshow",WS_OVERLAPPEDWINDOW,rect.left,rect.top,
rect.right-rect.left,rect.bottom-rect.top,0,0,wc.hInstance,0);
::ShowWindow(g_hwnd,nShowCmd);
//结束建立播放器主窗口

//我们将使用g_hwnd来接受directshow的消息：
g_pMediaEventEx->SetNotifyWindow((OAHWND)g_hwnd,WM_GRAPH_NOTIFY, NULL);

//建立Graph:
g_pMediaControl->RenderFile(FILENAME);

//向 directshow 询问 VideoWindow 接口:
pGraphBuilder->QueryInterface(IID_IVideoWindow,(LPVOID*)&pVideoWindow);

pVideoWindow->put_Owner((OAHWND)g_hwnd); //视频窗口是我们g_phwnd的子窗口！
pVideoWindow->put_WindowStyle(WS_CHILD|WS_CLIPSIBLINGS);
pVideoWindow->SetWindowPosition(0,0,rect.right-rect.left+1,rect.bottom-rect.top+1);
pVideoWindow->put_Visible(OATRUE);

//start playing media:
g_pMediaControl->Run();

MSG msg;
do
{
GetMessage(&msg,0,0,0);
::TranslateMessage(&msg);
::DispatchMessage(&msg);
if(msg.message==WM_GRAPH_NOTIFY)OnGraphNotify();
}while(!g_bExit); //消息循环,直到 g_bExit=TURE 时结束

//释放资源:
g_pMediaEventEx->Release();
pVideoWindow->Release();
g_pMediaControl->Release();
pGraphBuilder->Release();

//COM 终止:
CoUninitialize();

return 0;
}

void OnGraphNotify()
{
long evCode;
LONG param1, param2;
while(SUCCEEDED(g_pMediaEventEx->GetEvent(&evCode,&param1, &param2, 0)))
{
g_pMediaEventEx->FreeEventParams(evCode, param1, param2);
switch (evCode)
{
case EC_COMPLETE: //我们的媒体播放结束了
g_pMediaPosition->put_CurrentPosition(0); //重设播放位置为0，就是倒回的意思
g_pMediaControl->Run();//重新播放
                                //以上这样，就是循环播放！
break;  
};
};
}

LRESULT WINAPI WinProc(HWND hwnd,UINT msg,WPARAM wparam,LPARAM lparam)
{
switch(msg)
{
case WM_DESTROY:
g_pMediaControl->Stop(); //停止播放

break;
};
return DefWindowProc(hwnd,msg,wparam,lparam);

}

3。进一步实现游戏中的一些需要（播放暂停，循环，Esc跳过动画播放等）
使用另一种方式循环播放：
用一个定时器，每1000ms检查一下当前播放位置，如果播放到结束，就重放一遍。
