The + displayRect() property is used to set the region of the window the + video should be rendered to, and the aspectRatioMode() property + indicates how the video should be scaled to fit the displayRect(). + + \code + QVideoWindowControl *windowControl = mediaService->control<QVideoWindowControl *>(); + windowControl->setWinId(widget->winId()); + windowControl->setDisplayRect(widget->rect()); + windowControl->setAspectRatioMode(Qt::KeepAspectRatio); + \endcode + + QVideoWindowControl is one of number of possible video output controls, + in order to receive video it must be made the active video output + control by setting the output property of QVideoOutputControl to \l {QVideoOutputControl::WindowOutput}{WindowOutput}. + Consequently any QMediaService that implements QVideoWindowControl must + also implement QVideoOutputControl. + + \code + QVideoOutputControl *outputControl = mediaService->control<QVideoOutputControl *>(); + outputControl->setOutput(QVideoOutputControl::WindowOutput); + \endcode + + The interface name of QVideoWindowControl is \c com.nokia.Qt.QVideoWindowControl/1.0 as + defined in QVideoWindowControl_iid. + + \sa QMediaService::control(), QVideoOutputControl, QVideoWidget +*/ + +/*!
