Capturing QR codes using mergAV - how to?

[Terry Judd]

Hi – I’m trying to build a simple iOS app to capture and decode QR codes (for marking student attendance at compulsory activities) and am a bit stuck getting the mergAV external to work its magic.

I can capture an image ok using the mergAVPick() function with the rear camera but I was thinking that perhaps I should be using mergAVCamCaptureImage instead? If so then I’m going wrong somewhere as it does nothing when I call that command. I’m assuming I need to call mergAVCamCreate first and then set it up using the mergAVCamSet command. Is that right?

I seem to recall someone mentioning that they were using mergAV successfully to ‘scan’ QR codes a while back (and that it was superior to mergXZing in that regard). Does anyone have any tips/samples they would be willing to share?

Best regards.
