Problem\bug with scanner.html + feature suggestion

[iuvi7]

Hello!

I found bug with a scanner of QR codes:

When i use my PC web-cam in offline mode without internet - it works straight forward and i can recive files throught QR codes from my phone

But, when i start scanner.html on my phone to recive something from PC - it does not "get" my camera, not show it up and even don't ask permission in my browser to use it (it is allowed in settings and i try different browsers too). Only version with internet connection works really well on my phone - so that's why i stuck :( It would be cool to use it fully no-connection to the world

• I would like to suggest to make speed controller of broadcasting QR codes, because sometimes 1-2-3 QR's are get lost due high speed of showing up

Thank you for your work :)
