zbar
ZBar is an open source software suite for reading bar codes from various sources, including webcams. As its development stopped in 2012, I took the task of keeping it updated with the V4L2 API. This is the main repository for it. There's a clone at at LinuxTV.org, and another one at gitlab. (by mchehab)

Is there an open source QR code reader for Windows?
If it is in OpenCV probably you can use code from tutorials? (https://learnopencv.com/opencv-qr-code-scanner-c-and-python/) Or ZBar: http://zbar.sourceforge.net/ https://github.com/mchehab/zbar - there are builds for Windows

Is this a special type of barcode? What can I know about it?
I'm interested in getting the information this barcode means - as a sequence of numbers / letters or what ever. I didn't manage to get information with zbar. If it's not possible to detect the information itself, I'd be glad to be able to tell how much information this format can hold.

How to decode a QR-code image in (preferably pure) Python?
ZBar (website here) claims to be "an open source software suite for reading bar codes from various sources, such as image files." So I tried installing it on Mac OSX running sudo pip install zbar. This fails with error: command 'cc' failed with exit status 1. I tried to suggestions in the answers to this SO question, but I can't seem to solve it. So I decided to move on again:
