Im just playing around with the raspberry pi 3b and live scanning qr codes. Already tried CV2 library for scanning qr codes, but the live stream on rasp pi starts lagging and has a 5 sec video delay. Hence there is not enough ram (mine has 1gb)
Is there any less ram demanding library that could work good on rasp pi 3b and efficiently scan qr codes. (Just in case I need only qr codes, not any other)
Thanks in advance!
