How to get video from USB port?

[Wolf]

Hello!
I'm developing a program where I need to have video input.
It works fine if I use a video capture card. But how can I get it from a camera connected to the USB port? (Like a web camera)

If it doesn't work the same way its because the USB capture device doesn't provide a driver that exposes the VFW API calls.

I could be talking rubbish because I only scratched the surface in a recently developed app which takes live video input. I had similar problems to you when using USB and parallel port capture devices.

Also, I found that alot of Capture Cards do not provide NT4 drivers so I had even those problems to contend with!.

Did you use API calls yourself (way hard) or did you use a third party control when you got it working with the video capture card?

I'm using API calls.
So, if I can't use the AFW API calls, How can I do it then????
I havn't tryed my app with NT, but I'm not surprised if it's like you say.
