Yet another QR Code reader - Raspberry Pi Forums
i'm trying use library zbar scan qr codes using raspberry pi's camera module. i've connected , tested camera, don't know how access library because isn't on /dev/video0 or location can find. went http://www.linux-projects.org/modules/s ... e&artid=16 , followed these instructions: after can use camera , can find on /dev/video0 through " ls /dev/video* " . however, when run zbar through python, doesn't work and, afterwards, " ls /dev/video* " returns no results!
code use similar 1 in here:http://nullege.com/codes/show/src@z@b@z ... .processor
not sure path should taking make zbar work or, worse, read qr codes @ all. so, glad other ideas, specially if they're simpler 1 i'm trying now.
thank you

there have ended being 2 v4l2 drivers on pi - closed source uv4l2 have found, , more normal kernel driver provided foundation can loaded (it isn't loaded default steals load of memory on loading isn't helpful many other applications).
if have code should sort of work, push github or similar , 1 of people involved in developing driver may able (no promises though). based on code link to, i'd guess can't cope h264 data , wants yuv or rgb format , can't see setting up.

sudo modprobe bcm2835-v4l2
