C++ (Cpp) QMediaObject Examples

Example #1

File: cameramodecontrol.cpp Project: Quent-in/Textractor

void CameraModeControl::setDevice(const QString &device)
{
    if(device != m_device)
    {
        m_device = device;

        if(m_camera)
        {
            QMediaObject *mediaObject =
                    m_camera ? qobject_cast<QMediaObject *>(m_camera->property("mediaObject").value<QObject*>())
                             : nullptr;

            if(mediaObject)
            {
                QVideoDeviceSelectorControl *videoDevice =
                        mediaObject->service()->requestControl<QVideoDeviceSelectorControl*>();

                if(videoDevice)
                {
                    const int value = ("primary" == device) ? 0 : 1;

                    if(videoDevice->selectedDevice() != value)
                    {
                        videoDevice->setSelectedDevice(value);
                    }
                }
            }
        }

        emit deviceChanged(m_device);
    }
}
