Hi 🙂🖐

In this post, i will show you how to Detect QR codes in videos using Python

step 1

You need any video that contains a QR code.

step 2

import libraries


from pyzbar.pyzbar import decode
from PIL import Image

import moviepy.editor as mp

step 2

Write Qrcode Detector



from pyzbar.pyzbar import decode
from PIL import Image

import moviepy.editor as mp


def decode_image(image_array):
    result = decode(Image.fromarray(image_array))
    return result

def get_frames():
    video = mp.VideoFileClip('test.mp4')
    for i, frame in enumerate(video.iter_frames()):
        result = decode_image(frame)
        if result:
            print(f' Qrcode code detected in frame : {i} 🙂')
            print(f'Qrcode date : {str(result[0][0])}')



get_frames()

Result :

 Qrcode code detected in frame : 149 🙂
 Qrcode data : b'123'
 Qrcode code detected in frame : 150 🙂
 Qrcode data : b'123'
 Qrcode code detected in frame : 151 🙂
 Qrcode data : b'123'
