How to use QR codes on Mobian Sid(unstable) Pinephone Pro - biketool - 01-02-2025

With Mobian Sid we get a working libcamera so we can pipewire the sensors to the camera app.
Unlike Megapixels, which doesn't work yet on PPpro(some have succeeded in compiling in trixie), the system Camera app doesn't have a built-in QR reader.
It is a bit of a kludge but installing qtqr (it is a desktop package and needs scaling in Mobile Settings to work correctly, bring reading glasses)

Code:
sudo apt install qtqr

lets you snap a photograph, then load that photo as a file in qtqr and either directly open a web link or load the text into the editor window on qtqr.
unless you really want a record of all the QR codes you read delete the files when finished. Qtqr cannot currently find the camera device so itonly works in this indirect way.
A kludge for now, extra steps, but I use my camera more to read QR codes than to shoot pictures.

I mostly use simple QR code plugin for firefox to generate QR weblinks on computer that I read with my phone.

package "zbar-tools" in debian is worth mentioning. it bring "zbarimg" console program, which can scan image files for qr codes and other code standards.
