Re: Quickcam device driver for Linux

  Note that there already has been a linux kernel driver available
called "qcam-kernel-0.1". I doubt it's maintained because it's been
the same version for over a year now.. I use it for a realtime gif
or jpeg server push program I wrote. It only spits out raw image information,
but then I use libjpeg to compress it for me. I didn't see any need
for the image conversion to occur within the kernel module.
