QCameraViewfinder: How to remove last frame after disconnection
I hava a QCameraViewfinder connected to
a QCamera. After the device disconnection, the
last received frame still in the viewfinder.
How can I make the app reset the viewfinder
to a Black Screen automatically? There are signals for this? Or properties?
Thanks in advice.
from your QCameraViewfinder object, get the QMediaObject pointer.
[virtual] QMediaObject *mediaObject() const
then, from this pointer get the QMediaService * pointer.
[virtual] QMediaService *QMediaObject::service() const
This pointer gives you access to the mediaplayer controle
QMediaPlayerControl *control = qobject_cast<QMediaPlayerControl *>(
