@Faisal_Ali You didn't explain/show what you tried so far. Can you show your code?

@Faisal_Ali See here http://doc.qt.io/qt-5/qcamera.html

QList<QCameraInfo> cameras = QCameraInfo::availableCameras();
foreach (const QCameraInfo &cameraInfo, cameras) {
    if (cameraInfo.deviceName() == "mycamera")
        camera = new QCamera(cameraInfo);
}

You just need one QCamera instance for each of your cameras. Then you can use one QCameraViewfinder/QMediaRecorder for each of those QCamera instances.

Hi,

Since you are using OpenCV to grab images from your camera, why not ask that question to the OpenCV folks ?
