If you want access to video devices, Microsoft DirectShow is a great place
to start. I have been working on a machine vision app using Smalltalk MT,
and am able to get video easily from usb cams, frame grabbers, ip cameras,
fire wire etc. You will find that DirectShow support is available from many
many camera vendors. I am just wrapping the com interfaces of directshow.
I'm not familiar with Dolphin, but being Windows only, I imagine the support
for com should be good. There are type libraries available for creating
your smalltalk com wrappers, and there is a very active newsgroup for
DirectShow development at microsoft.public.win32.programmer.directx.video.
