C++ (Cpp) ComPointer::SetAspectRatioMode Examples

Example #1

File: videorenderer_evr.cpp Project: selebro/qt

VideoRendererEVR::VideoRendererEVR(QWidget *target) : m_target(target)
{
    m_filter = Filter(CLSID_EnhancedVideoRenderer, IID_IBaseFilter);
    if (!m_filter) {
        return;
    }

    ComPointer<IMFVideoDisplayControl> filterControl = getService<IMFVideoDisplayControl>(m_filter, MR_VIDEO_RENDER_SERVICE, IID_IMFVideoDisplayControl);

    filterControl->SetVideoWindow(reinterpret_cast<HWND>(target->winId()));
    filterControl->SetAspectRatioMode(MFVideoARMode_None); // We're in control of the size
}
