* History:
* This source code is based heavily on the CPiA webcam driver which was
* written by Peter Pregler, Scott J. Bertin and Johannes Erdfelt
*
* 2001_07_07 - 0.1 - christopher: first version
* 2001_08_28 - 0.2 - pavel: messed it up, but for some fun, try
while true; do dd if=/dev/video of=/dev/fb0 bs=$[0x1e480] count=1 2> /dev/null; done
yep, moving pictures.
* 2001_08_29 - 0.3 - pavel: played a little bit more. Experimental mmap support. For some fun,
get gqcam-0.9, compile it and run. Better than dd ;-).
* 2001_08_29 - 0.4 - pavel: added shutter speed control (not much functional)
kill update_params if it does not seem to work for you.
* 2001_08_30 - 0.5 - pavel: fixed stupid bug with update_params & vicam_bulk
* Portions of this code were also copied from usbvideo.c
*
* FIXME: It crashes on rmmod with camera plugged.
*/
#define DEBUG 1
* Special thanks to the the whole team at Sourceforge for help making
* this driver become a reality. Notably:
* Andy Armstrong who reverse engineered the color encoding and
* Pavel Machek and Chris Cheney who worked on reverse engineering the
* camera controls and wrote the first generation driver.
