Barcode scanner web-app

html5 offers the getUserMedia() to capture the stream of camera data.

"getUserMedia()" is not supported by all browsers but it works with Chrome and Opera (but not FF) on Android when I tested it.

It seems to be an issue with auto-focus though, a few devices like HTC seem to work but most seem not to work. ref, ref

Example of barcode-libary that uses getUserMedia():
