详细描述
The QVideoRendererControl class provides a media control for rendering video to a QAbstractVideoSurface.
Using the surface() property of QVideoRendererControl a QAbstractVideoSurface may be set as the video render target of a QMediaService.
QVideoRendererControl *rendererControl = mediaService->requestControl<QVideoRendererControl *>(); rendererControl->setSurface(myVideoSurface);
QVideoRendererControl is one of a number of possible video output controls.
The interface name of QVideoRendererControl is org.qt-project.qt.videorenderercontrol/5.0 as defined in QVideoRendererControl_iid.
参见 QMediaService::requestControl() and QVideoWidget.
