    @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.

    @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).
