I suggest you get a card with 4 or more brooktree capture chips
on it. You might get some help from the techwell link below on
getting the card to switch video inputs (you would probably have
to make your own software). Get a copy of the vidcap32.exe from
the below links and see if it recognizes your card. If it does,
then most other webcam applications should be able to use your
card. You should be able to use the BDLCam (for cam control) and
a webcam application at the same time (would need to be running
on different ports) on the same web page. Note that a webcam
application and the pico2000soft ware cannot be running at the
same time under normal conditions. Bottom link shows a way to
send the bytes to the serial port from a web page.
