Detailed Description¶

The winId() property QVideoWindowControl allows a platform specific window ID to be set as the video render target of a QMediaService . 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() .
QVideoWindowControl *windowControl = mediaService->requestControl<QVideoWindowControl *>();
windowControl->setWinId(widget->winId());
windowControl->setDisplayRect(widget->rect());
windowControl->setAspectRatioMode(Qt::KeepAspectRatio);
QVideoWindowControl is one of a number of possible video output controls.

The interface name of QVideoWindowControl is org.qt-project.qt.videowindowcontrol/5.0 as defined in QVideoWindowControl_iid .
