You can do everything necessary with the video stream from within a
QuickTime digitizer component that resides in user-space.
Tiger ships with a VDIG that support USB cameras that adhere to the
Video Device Class spec. It is implemented entirely with the
QuickTime component.

Dear all,
I am preparing to write a driver for a USB camera. It is just a
normal USB camera for chatting on PC. It uses ISO transferring for
video.
Because I am a new one for Mac OS X. I am not sure whether I should
write a driver inside the kernel mode, or, just put it into user
space. My target is to write a driver and let common applications
like HackTV and so on to work with the driver. Is it possible?
And now, on my opinion, two components are needed, one is driver
inside kernel or user space, the other is the QT
component(digitizer). Is it correct?
Thanks
VL
