sane-v4l - SANE interface for Video for Linux API
The sane-v4l library implements a SANE (Scanner Access Now Easy) backend
that provides generic access to video cameras and similar equipment
using the V4L (Video for Linux) API.
This backend expects device names of the form:
Where special is the UNIX path-name for the special device that corresponds
to the v4l device. The special device name must be a v4l device
or a symlink to such a device. For example, such a device name could
be /dev/video0 or /dev/bttv0.
The contents of the v4l.conf file is a list of device names that correspond
to v4l devices. Empty lines and lines starting with a hash mark
(#) are ignored. A sample configuration file is shown below:

The shared library implementing this backend (present on systems
that support dynamic loading).
This environment variable specifies the list of directories that
may contain the configuration file. Under UNIX, the directories
are separated by a colon (`:'), under OS/2, they are separated
by a semi-colon (`;'). If this variable is not set, the configuration
file is searched in two default directories: first, the
current working directory (".") and then in /etc/sane.d. If the
value of the environment variable ends with the directory separator
character, then the default directories are searched after
the explicitly specified directories. For example, setting
SANE_CONFIG_DIR to "/tmp/config:" would result in directories
"tmp/config", ".", and "/etc/sane.d" being searched (in this
SANE_DEBUG_V4L [Toc] [Back]
If the library was compiled with debug support enabled, this
environment variable controls the debug level for this backend.
E.g., a value of 128 requests all debug output to be printed.
Smaller levels reduce verbosity.

If more than one video card is present, a crash may occur.
