Want to show detect camera using QCamera

[xylo212]

Actually, I want to access camera inside oven and but In my case I'm it's showing camera not found...

When I try to run sample code for detecting the camera of my pc and I'm able to do it,
Can anyone tell what approach I need to do for detecting the camera inside oven

This is my code->>

layout = new QVBoxLayout(this);
QList<QCameraInfo> cameras = QCameraInfo::availableCameras();
if (cameras.isEmpty()) {
qDebug() << "No cameras found.";
return;
}
camera = new QCamera(cameras.first());
viewfinder = new QCameraViewfinder();
layout->addWidget(viewfinder);

    // Set the camera viewfinder
    camera->setViewfinder(viewfinder);
    camera->start();

Oven?! What oven? How is the camera connected to your device/computer?

actually, when I try to run qt application on my system/PC in which we access PC camera, easily

Hi,

That does not answer the how is the camera accessed.
It is a USB device ? A network camera ?

[xylo212]

USB camera

Do you mean Qt example code? If so then compare that code with what you're doing.

[xylo212]

yeah, I already done it but still not able to detect USB camera

What are you doing differently between your code and the working example ?

I assume @xylo212 is talking about a different camera... the camera from the computer works, while the "oven camera" (whatever it is) does not... maybe driver or connection issue.
No one can tell if @xylo212 doesn't provide more info.
