DirectDraw7::CreateSurface failed!

直接贴代码，在我的机器上能创建成功，别人机器上不行，还有就是如何判断显卡是否直接显示YUV图像

if (FAILED(DirectDrawCreateEx(NULL, (void **)&g_lpDDraw, IID_IDirectDraw7, NULL)))

		{

			AfxMessageBox("Create DirectDraw failed!");

			return;

		}

		g_lpDDraw->SetCooperativeLevel(GetDlgItem(IDC_PLAYWND)->m_hWnd, DDSCL_NORMAL);



		DDSURFACEDESC2 ddsd;

		memset(&ddsd, 0, sizeof(ddsd));

		ddsd.dwSize = sizeof(ddsd);

		ddsd.dwFlags = DDSD_CAPS;

		ddsd.ddsCaps.dwCaps = DDSCAPS_PRIMARYSURFACE;

		if (FAILED(g_lpDDraw->CreateSurface(&ddsd, &g_lpDDSurfacePrimary, NULL)))

		{

			AfxMessageBox("Create Primary Surface failed!");

			_close(g_fdread);

			g_fdread = -1;

			g_lpDDraw->Release();

			g_lpDDraw = NULL;

			return;

		}

		

		DDPIXELFORMAT ddpf;

		memset(&ddpf, 0, sizeof(ddpf));

		ddpf.dwSize = sizeof(ddpf);

		g_lpDDSurfacePrimary->GetPixelFormat(&ddpf);

		ddpf.dwFlags = DDPF_FOURCC;

		ddpf.dwFourCC = mmioFOURCC('I', '4', '2', '0');



		memset(&ddsd, 0, sizeof(ddsd));

		ddsd.dwSize = sizeof(ddsd);

		ddsd.dwFlags = DDSD_CAPS | DDSD_HEIGHT | DDSD_WIDTH | DDSD_PIXELFORMAT;

		ddsd.ddsCaps.dwCaps = DDSCAPS_OFFSCREENPLAIN | DDSCAPS_VIDEOMEMORY;

		ddsd.dwHeight = 288;

		ddsd.dwWidth = 352;

		ddsd.ddpfPixelFormat = ddpf;

		if (FAILED(g_lpDDraw->CreateSurface(&ddsd, &g_lpDDSurfaceOffscreen, NULL))) //这里就会失败

		{

			AfxMessageBox("Create offscreen Surface failed!");

                 }
