[Solved] C# – Upload video and read QR codes in it

by


Sounds like there are two parts to this question:

1. Getting an image from a video

I suppose you manage to do this since you did not provide any info on the video file format.

2. Detecting a QR code in an image.

Multiple options exist:

  1. Use the AForgeTry using AForge.NET library for capturing the video from your webcam, and then ZXing.Net library for reading the QR codes: see QR code webcam scanner c#

  2. See Decode QR-Code in WPF By Zxing
