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 is ALPHA software. Really! Important features are missing and
there are lots of bugs. The code is currently only tested on a Linux
2.4 system with a Hauppauge WinTV video card.
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 backend configuration file (see also description of
The static library implementing this backend.
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 order).
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. Frequency
and geometry selection is missing.
