I am waiting for ideas on getting this task done.Thank you!

+1  A: 

If you want the movie to be accessible to webcam-related APIs and OS features, then yes, you would need to write (or find a thirdp-party) device driver that is usable by multimedia APIs.

+2  A: 

You'll want to take a look at the Windows Image Acquisition service. At first glance it looks like you're correct. You will probably have to write a user mode driver to do this. Once this is accomplished you should be able to stream your movie through any software that takes advantage of a webcam.

Just intercept the data that is being sent out on the web server.

I do not think the OP intends to send anything via a web server. It got the feeling he just wants to use it like any video source, on the same footage as TV tuners etc.
