Quirc is a small, dependency-free C library for extracting and decoding QR codes from images, fast enough for realtime video. It handles rotated, oblique, and multiple codes per frame and is easily embeddable with a tiny memory footprint.
Use cases
- decode qr codes from images in c
- realtime qr code scanning from camera video
- embed qr decoder in embedded device
- detect multiple qr codes in one image
- build a barcode scanner app
- decode rotated or skewed qr codes
When to choose
- you need a lightweight, portable QR decoder with no dependencies
- you need realtime decoding from video frames
- you need multithread-safe decoding of multiple codes per image
- you target embedded or resource-constrained platforms
When to avoid
- you need to decode barcode formats other than QR codes
- you want a high-level library with camera and UI integration built in
- you need pure Python/Java tooling rather than a C library
