Has anyone scanned barcodes through a webcam attached to the Galileo? I attempted to use the zbar library, building it on my kubuntu machine just to try it out, but it seems that the stable release has deprecated (and unsupported) dependencies, while the latest github version has its own issues (can't find installed packages). I have never used opencv or v4l, so I am unaware how much effort it would be to write my own program to read barcodes. Has anyone completed a project similar to this one? Is there something obvious I am missing?
