creating a new device

creating a new device

[Norman Specht]

Hi,

i'm trying to develop a image preprocessor which takes the image from a
webcam (e.g /dev/video0), modifies it and render it to a second
device (e.g /dev/myVideo0).

Grabbing the picture from the webcam isn't the problem but my problem is: How can i create a device which behaves like a webcam?

I'm running a ubuntu 8.10, and i tried including the kernel headers (media/v4l2-common.h, etc.) in many different ways to make my g++ compile my program. Is there some special way to do this?

Bye

Norman Specht
