QRCode autoscanning freeze app

Hi, i need to create an app that auto scan the camera every 0.5s to find a qrcode.

The app works but when i call the funcion

I tried with a separate thread but I can make some funcion like GetPixels32() outside the main thread.

I tried with a Dispatcher, with IJobParallelFor with task…

EVERYTHING freeze my app for a couple of frame when the funcion is called.

can anyone please help me?

to read the qrcode i used this:

Have you used a QR code recently outside of your app? On every phone I use, reading a QR code also freezes the entire phone for a few frames. I’m not sure it is Unity you’re having the problem with, and I’m not 100% sure what all that ZXing DLL attempts to do. You might want to contact the author of that package for more help.
