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

视频播放时d3d不渲染，不播放的时候才渲染

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