Qml usb camera shows picture with colored stripes



  • Hi,
    I am developing my application on Raspberry pi 4 with raspbian buster and qt5.12.7.
    Yesterday I created a image with a newer version of raspbian buster and now I have the problem that the cameras are not working.
    My application shows the following picture:
    camera.png

    Before the raspbian buster update the camera picture was shown correctly. I did not change the hardware nor the application itself.
    Does anybody know what this picutre means? Is there a problem with initializing the cameras or a general problem with the raspbian buster or maybe with the sd card?
    At the moment I have no idea what the problem is...

    Greetings



  • This looks like a kind of test image.
    Probably created by your Raspbian or QML as default image, when there is no camera picture or data available (haven't used both).

    How should it look like?
