该是自己动手来写的时候了，最简单的代码能突出重点。
自己建个win32项目，选择空项目。

CMovie类来自于
Microsoft Platform SDK for Windows Server 2003 R2/Samples/Multimedia/DirectShow/VMR9/VMRPlayer/
中的vcdplyer.h，做了一点修改。

程序主体代码用了Direct3D Tutorial 3: Using Matrices的部分代码。

截图：
        播放

        不播放

项目配置：

#include <streams.h>

位于Microsoft Platform SDK for Windows Server 2003 R2/Samples/Multimedia/DirectShow/BaseClasses

链接：只有这三个d3d9.lib Strmiids.lib Quartz.lib

使用 Unicode 字符集
多线程调试 DLL (/MDd)

核心代码：
INT WINAPI WinMain( HINSTANCE hInst, HINSTANCE, LPSTR, INT )<br /> {<br /> // Register the window class<br /> WNDCLASSEX wc = { sizeof(WNDCLASSEX), CS_CLASSDC, MsgProc, 0L, 0L,<br /> GetModuleHandle(NULL), NULL, NULL, NULL, NULL,<br /> L"D3D Tutorial", NULL };<br /> RegisterClassEx( &wc );</p> <p> // Create the application's window<br /> g_hwnd = CreateWindow( L"D3D Tutorial", L"DShow CMovie Test",<br /> WS_OVERLAPPEDWINDOW, 100, 100, 300, 300,<br /> NULL, NULL, wc.hInstance, NULL );</p> <p> g_pMovie = new CMovie(g_hwnd);<br /> g_pMovie->OpenMovie(L"C://Program Files//Microsoft Platform SDK for Windows Server 2003 R2//Samples//Multimedia//DirectShow//Media//Video//ruby.avi");<br /> g_pMovie->PlayMovie();</p> <p> // Initialize Direct3D<br /> if( SUCCEEDED( InitD3D( g_hwnd ) ) )<br /> {<br /> // Show the window<br /> ShowWindow( g_hwnd, SW_SHOWDEFAULT );<br /> UpdateWindow( g_hwnd );</p> <p> // Enter the message loop<br /> MSG msg;<br /> ZeroMemory(&msg, sizeof(msg));<br /> while(msg.message != WM_QUIT)<br /> {<br /> if( PeekMessage( &msg, NULL, 0, 0, PM_REMOVE ) )<br /> {<br /> TranslateMessage( &msg );<br /> DispatchMessage( &msg );<br /> }<br /> else<br /> {<br /> Render();<br /> }<br /> }<br /> }</p> <p> UnregisterClass( L"D3D Tutorial", wc.hInstance );<br /> return 0;<br /> }

视频播放时d3d不渲染，不播放的时候才渲染

VOID Render()<br /> {</p> <p> if(g_pMovie->IsPlaying())<br /> {<br /> RECT rc;<br /> ::GetClientRect(g_hwnd, &rc);<br /> g_pMovie->PutMoviePosition(rc.left, rc.top, rc.right - rc.left, rc.bottom - rc.top);<br /> g_pMovie->RepaintVideo(g_hwnd, ::GetDC(g_hwnd));<br /> }<br /> else<br /> {<br /> if( NULL == g_pd3dDevice )<br /> return;</p> <p> // Clear the backbuffer to a blue color<br /> g_pd3dDevice->Clear( 0, NULL, D3DCLEAR_TARGET, D3DCOLOR_XRGB(0,0,255), 1.0f, 0 );</p> <p> // Begin the scene<br /> if( SUCCEEDED( g_pd3dDevice->BeginScene() ) )<br /> {<br /> // Rendering of scene objects can happen here<br /> // End the scene<br /> g_pd3dDevice->EndScene();<br /> }</p> <p> // Present the backbuffer contents to the display<br /> g_pd3dDevice->Present( NULL, NULL, NULL, NULL );<br /> }<br /> }
