I don't think this is directly possible. You could try to use QWidget::createWindowContainer to start a browser and capture its full window. Some smart event filtering could then resize and move ...

@mtalha2621 My bad, I misread the error messages. What I had in mind when answering is for you to use your custom pipeline with OpenCV.

Hi, Please provide a minimal compilable example that shows the situation.

Hi and welcome to devnet, Did you build that software yourself ? Where did you get the sources from ? Which version of Qt are you using ? How did you install it ?

@Cedric-air No, that shows it is not optional, it shows that you should not be trying to alter itemInfo in the signal/slot. But your commented out/erroneous code was trying to set that visible.

@Chs_QtLearner Please check config.log file to see why Open62541 security was disable (most probably some lib is missing).
