我正在尝试使用以下代码：
HRESULT hResult;
HDC hDC;
IDXGISurface1 *pSurface = NULL;
hResult = m_flashTexture->QueryInterface(__uuidof(IDXGISurface1), (void**)&pSurface);
hResult = pSurface->GetDC(TRUE, &hDC);
assert(SUCCEEDED(hResult));
m_flashPlayer->DrawFrame(hDC);
drawFrame 在哪里...
void CFlashDXPlayer::DrawFrame(HDC dc)
{
if (m_dirtyFlag)
{
IViewObject* pViewObject = NULL;
m_flashInterface->QueryInterface(IID_IViewObject, (LPVOID*) &pViewObject);
if (pViewObject != NULL)
{
// Combine regions
HRGN unionRgn, first, second = NULL;
unionRgn = CreateRectRgnIndirect(&m_dirtyRects[0]);
if (m_dirtyRects.size() >= 2)
second = CreateRectRgn(0, 0, 1, 1);
for (std::vector<RECT>::iterator it = m_dirtyRects.begin() + 1; it != m_dirtyRects.end(); ++it)
{
// Fill combined region
first = unionRgn;
SetRectRgn(second, it->left, it->top, it->right, it->bottom);
unionRgn = CreateRectRgn(0, 0, 1, 1);
CombineRgn(unionRgn, first, second, RGN_OR);
DeleteObject(first);
}
if (second)
DeleteObject(second);
RECT clipRgnRect; GetRgnBox(unionRgn, &clipRgnRect);
RECTL clipRect = { 0, 0, m_width, m_height };
// Fill background
if (m_transpMode != TMODE_FULL_ALPHA)
{
// Set clip region
SelectClipRgn(dc, unionRgn);
COLORREF fillColor = GetBackgroundColor();
HBRUSH fillColorBrush = CreateSolidBrush(fillColor);
FillRgn(dc, unionRgn, fillColorBrush);
DeleteObject(fillColorBrush);
// Draw to main buffer
HRESULT hr = pViewObject->Draw(DVASPECT_TRANSPARENT, 1, NULL, NULL, NULL, dc, &clipRect, &clipRect, NULL, 0);
assert(SUCCEEDED(hr));
}
else
{
if (m_alphaBlackDC == NULL)
{
// Create memory buffers
BITMAPINFOHEADER bih = {0};
bih.biSize = sizeof(BITMAPINFOHEADER);
bih.biBitCount = 32;
bih.biCompression = BI_RGB;
bih.biPlanes = 1;
bih.biWidth = LONG(m_width);
bih.biHeight = -LONG(m_height);
m_alphaBlackDC = CreateCompatibleDC(dc);
m_alphaBlackBitmap = CreateDIBSection(m_alphaBlackDC, (BITMAPINFO*)&bih, DIB_RGB_COLORS, (void**)&m_alphaBlackBuffer, 0, 0);
SelectObject(m_alphaBlackDC, m_alphaBlackBitmap);
m_alphaWhiteDC = CreateCompatibleDC(dc);
m_alphaWhiteBitmap = CreateDIBSection(m_alphaWhiteDC, (BITMAPINFO*)&bih, DIB_RGB_COLORS, (void**)&m_alphaWhiteBuffer, 0, 0);
SelectObject(m_alphaWhiteDC, m_alphaWhiteBitmap);
}
HRESULT hr;
HBRUSH fillColorBrush;
// Render frame twice - against white and against black background to calculate alpha
SelectClipRgn(m_alphaBlackDC, unionRgn);
COLORREF blackColor = 0x00000000;
fillColorBrush = CreateSolidBrush(blackColor);
FillRgn(m_alphaBlackDC, unionRgn, fillColorBrush);
DeleteObject(fillColorBrush);
hr = pViewObject->Draw(DVASPECT_TRANSPARENT, 1, NULL, NULL, NULL, m_alphaBlackDC, &clipRect, &clipRect, NULL, 0);
assert(SUCCEEDED(hr));
// White background
SelectClipRgn(m_alphaWhiteDC, unionRgn);
COLORREF whiteColor = 0x00FFFFFF;
fillColorBrush = CreateSolidBrush(whiteColor);
FillRgn(m_alphaWhiteDC, unionRgn, fillColorBrush);
DeleteObject(fillColorBrush);
hr = pViewObject->Draw(DVASPECT_TRANSPARENT, 1, NULL, NULL, NULL, m_alphaWhiteDC, &clipRect, &clipRect, NULL, 0);
assert(SUCCEEDED(hr));
// Combine alpha
for (LONG y = clipRgnRect.top; y < clipRgnRect.bottom; ++y)
{
int offset = y * m_width * 4 + clipRgnRect.left * 4;
for (LONG x = clipRgnRect.left; x < clipRgnRect.right; ++x)
{
BYTE blackRed = m_alphaBlackBuffer[offset];
BYTE whiteRed = m_alphaWhiteBuffer[offset];
m_alphaBlackBuffer[offset + 3] = 255 - (whiteRed - blackRed);
offset += 4;
}
}
// Blit result to target DC
BitBlt(dc, clipRgnRect.left, clipRgnRect.top,
clipRgnRect.right - clipRgnRect.left,
clipRgnRect.bottom - clipRgnRect.top,
m_alphaBlackDC, clipRgnRect.left, clipRgnRect.top, SRCCOPY);
}
DeleteObject(unionRgn);
pViewObject->Release();
}
m_dirtyFlag = false;
m_dirtyRects.clear();
m_dirtyUnionRect.left = m_dirtyUnionRect.top = LONG_MAX;
m_dirtyUnionRect.right = m_dirtyUnionRect.bottom = -LONG_MAX;
}
}
我还应该提到我使用以下设置 m_flashTexture：
D3D11_TEXTURE2D_DESC textureDesc;
ZeroMemory(&textureDesc, sizeof(textureDesc));
textureDesc.Width = width;
textureDesc.Height = height;
textureDesc.MipLevels = 1;
textureDesc.ArraySize = 1;
textureDesc.Format = DXGI_FORMAT_B8G8R8A8_UNORM;
textureDesc.SampleDesc.Count = 1;
textureDesc.Usage = D3D11_USAGE_DEFAULT;
textureDesc.BindFlags = D3D11_BIND_SHADER_RESOURCE | D3D11_BIND_RENDER_TARGET;
textureDesc.MiscFlags = D3D11_RESOURCE_MISC_GDI_COMPATIBLE;
HRESULT hr = device->CreateTexture2D(&textureDesc, NULL, &m_flashTexture);
每当我运行此代码时（它还有更多内容，但它被埋在一堆其他类中，如果您认为其他东西有用，请告诉我。）我得到一个蓝屏死机，这是在 flashPlayer 的某个地方引起的->drawFrame() 函数。我不知道是什么导致了蓝屏。
任何想法或是否有人看到看起来会导致蓝屏的突出内容？
谢谢。
