There exists no documentation considering this subject.
All v4l capable video devices should be supported, please do take into account
you'll need a webcam which can focus.
To compile with webcam support use ccmake (as stated before in this thread) &
make sure the ENABLE_WEBCAM option is set to ON. Recompile afterwards.
You'll need the libv4l* & libksane* packages.
Afterwards when running Tellico make sure your webcam device is plugged in &
available. If so, when opening the Internet Search dialog a new dialog will
appear showing your webcams output, also a thread is started, taking images
from the video & attempting to recognise the barcode.
Hope this helps somewhat.
