I'm trying to use the library zbar to scan qr codes using Raspberry pi's camera module. I've connected and tested the camera, but I don't know how to access that from the library because it isn't on /dev/video0 or any location I can find. So I went here and followed these instructions:
raspberrypi ~ $ uv4l --driver raspicam --auto-video_nr --encoding h264 --width 1920 --height 1080
After that I can use my camera and can find it on /dev/video0 through " ls /dev/video* " . However, when I run zbar through python, it doesn't work and, afterwards, " ls /dev/video* " returns no results!
The code I use is very similar to the one in here
