The v4l api draft isn't terribly descriptive. You do it in kernel space because you want to plug into videodev.o interface. The driver will be very simple, it only needs to give prepared frames to anyone who cares to read. usbvideo module has several routines to fake video frames, but I am afraid this code is too big to be a good prototype. I believe there was a multi-part publication on LinuxToday or something, about a year ago, which contained several good samples. Dmitri -- Atlantis was lost because of the Y2K problem.
