    Hi,

    I have built and run the Camera Example project from the examples in Qt Creator.
    All went correctly.
    I can run the program and display video stream from my laptops camera (Lenovo X220) and from my phone (using DroidCam Client in the background).

    The example has many options, that you can change.
    I can use the sliders to adjust Exposure Compensation or Quality. But they do not appear to work.
    Nothing except form image capture does not appear to work. The same goes for the QML example.

    Is there a way to make the functions provided by the example work?
    Is there another way to make those changes?

    I am using Window 10 with the latest updates, but I have tried the example a couple moths ago, and the results were the same.

      Hi,

      You should add some check about the availability of the functions you are using. Not everything is available on all platforms.

        @SGaist Thank you for your answer.
        Could you point me to a place, where I can find some information about it?

          For example: QCameraImageProcessing
