I tried to reproduce your bug but for me zbarcam works without problem. Can you give some more information about the camera you used?

It's one of the built-in cameras on a TravelMate Spin B311R-31

Anything other information that may be relevant?

Interesting, can you try with the other camera? Probably
zbarcam /dev/video1

I imagine this could also be something in the kernel rather than in zbar-tools
but I haven't looked into that yet.

you can try:

mpv av://v4l2:/dev/video0

to test.

Cheers Jochen
