Great video, I'm having trouble getting the web cam to scan my barcode. The program is working, but the specific barcode I need to use it with doesn't scan.

Hey, I am able to import the zbar libary but when i do import pyzbar.pyzbar import decode it is giving an error.

[hamas]

Thanks for this helpful tutorial, but can I know if pyzbar need some kind of internet to recognize the zbars? case main can't recognize any bar, its like that it didn't enter the loop.

[aleynaabanuz]

Thanks for THY video but I can’t install pyzbar. I mean I installed pyzbar but when I run the codes return some error. I tried install pyzbar via pip but it is same. There are many error message about dependencies. What is my mistake?

[ramister]

Thanks for your explanation! I do still have a question: stead of open a camera, can I read my screen and capture a QR code data from a video?

[lykapascual]

Hey man, It works great and without any problems.

[thanawintipyathon]

Thank a lot for this tutorial.
You can scan the code Then the program will show the value once And you can also scan the previous code again !?
