Tellico: using webcam to scan ISBN barcode
In theory it works like this: You hold the book's barcode closely in
front of the webcam, a snapshot is taken and interpreted and the
resulting numbers are inserted into the ISBN field.
In practice this has never worked for me. I've never made it even to the
point where a snapshot is taken of the barcode. Which left me wondering
if this feature works for anyone at all, or if the problem is related to
my setup.
I have a Logitech QuickCam Pro 9000, which ought to be good enough, but
unfortunately, is from a series whose firmware has issues with Linux[*].
However, it does work in Skype and [gl]uvcview, and in Tellico, when I
open the "Search the Internet" dialog, a functional camera window pops-
up in addition. As far as I can tell, the problem may be that the image
simply isn't sharp when I hold the barcode close enough to the camera.
I'm using Tellico 2.1.1-2, the system is a current Debian/unstable.

My exemplar has USB BCD 0x0008, but I'm not affected by the "hanging"
camera issue.
