Grabs images from NetBSD's or FreeBSD's /dev/bktr and ov511+ based
USB webcams and saves it as jpeg. That makes a nice console based
webcam program. 
This project started as bktr2jpeg and was (for several years) a
single C-source file that supported bktr-based devices only. After
adding support for USB webcams further features got added and the
list includes now an XML-based config file and a built-in mini
webserver for static and streaming images. There is a nice interface
between the camera driver and the rest of the program, so adding new
devices is not hard (beside writing the driver). Includes rc-scripts
for NetBSD's rc.d startup and shutdown scripts. 

For NetBSD's rc.d:
cambevao=YES    cambevao_flags="/usr/pkg/share/cambevao/cambevao.xml"

Full list for OV511-based cameras: http://alpha.dyndns.org/ov511/cameras.html

Every camera with an OV511+ bridge and an OV7620 sensor will
work. Other combinations will not work, yet, but are easy to
support. All I need is a willing tester or better a camera.

Recommended largest sizes for capturing:
bktr:
 PAL  is 768 x 576
 NTSC is 640 x 480
The driver will do the sizing in hardware and can do bigger, but
as the source ist that size it makes no sense to scale that up.

ov511:
 640 x 480
This is the biggest resolution the hardware can do. But there are
smaller modes which result in a much better picture quality. So
if you use something like 400x300, you'll be surprised.
All you need to know is, that width*height*2 should be smaller
then 524288.
So, the biggest "good" value is 640x408.
