@jsulm thanks alot

@najlou One simple way to do it is: create two images and toggle them in a qlabel with timer.

[najlou]

@jsulm please I added the image but when I activate the camera it will be hidden by the camera

[jsulm]

@najlou I did not say how you added the image...

[najlou]

@jsulm i added with label and i put in the scrollarea

[jsulm]

@najlou Can you post the code where you set up everything?

[najlou]

@jsulm
QString filename1=QDateTime::currentDateTime().toString(QString("'%1/CaméraAvant_'yyyy_MM_dd'_'hh_mm_ss'").arg(dossier));
//creation du filename qui contient l'emplacement du fichier et son nom
QFile file(filename1);
cameraAvant->setCaptureMode(QCamera::CaptureStillImage);//mode capture
cameraAvant->searchAndLock();//bloquage du camera
CameraImageCaptureAvant->capture(filename1);// prendre capture
cameraAvant->unlock();//debloquage du camera
QPixmap pix ("/home/pi/build-Rover-Desktop-Debug/Live.png");
ui->labelimage->setPixmap(pix);

@najlou This does not really help, as it does not show how the widgets are positioned (or put in layouts)...

[najlou]

@jsulm i placed the label in the scrollarea
so how can i do it please ?

if(ui->Cameratoggle->isChecked())
{
    ui->stackedWidget->setCurrentIndex(1);// la premiere page du stackedwidger qui contient la premiere camera
    ui->scrollArea_2->setLayout(layoutAvant);
    cameraAvant->start();
    cameraArriere->stop();

QPixmap pix ("/home/pi/build-Rover-Desktop-Debug/Live.png");
ui->labelimage->setPixmap(pix);

}
else {
    ui->stackedWidget->setCurrentIndex(0);
    ui->scrollArea->setLayout(layoutArriere);
    cameraArriere->start();
    cameraAvant->stop();

QPixmap pix ("/home/pi/build-Rover-Desktop-Debug/Live.png");
ui->labelimage->setPixmap(pix);

}

@najlou said in picture with a blinking effect:

i placed the label in the scrollarea

But how exactly? Is it over camera view? You need to really make it clear how everything is arranged exactly, else how should anybody know why the label disappears when you start to play video?
