Hey Kostadin, Thanks a lot for the video. It was really helpful. I'm that introvert who would watch videos and go silent without commenting in it. This video demands appreciation. Thanks again for the video.

Hello Kostadin. Your tutorial is very helpful. Can i know, how can i put the data that was printed into a variable. Then, i can just use the variable to play around with the data such as insert into a database. Thank you in advance for your help!

Hello, wonderful demo !!! Can you help me resolving the below issue pls ?

When I use import statement as "from pyzbar.pyzbar import decode" and run the code (without any other executable lines), am getting the error "ImportError: Unable to find zbar shared library".

P.S - I did brew the ZBAR and then installed the PYZBAR as mentioned in one of the forums but still no luck...

Thanks in advance !

*HELPFUL TIPS* (will update) :—

1. myVidCap = cv2.VideoCapture(0, cv2.CAP_DSHOW) # CAP_DSHOW api opens camera MUCH faster than CAP_MSMF, at least on Windows.
2. flippedHorizontal = cv2.flip(frame, 1) # Flipping the output about the Y-axis.
cv2.imshow("Testing-Code-Scan", flippedHorizontal) # Change "frame" to the operation carried out on it.

Hi,
This is great! May I ask if this would work with a Data Matrix?

[cocopalafox]

Great video, thanks for posting it. How do you stop the camera and get out of the while loop after reading ONE barcode? Thanks

[raghuram]

Do this code work for barcode scanning machine than webcam..?

[Mystery_Glitch]

I think it should be change to if the same code not get scan in a minute, it can rescan, it should be better if you make a bought list in supermarket
