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. +.PP +.SH "DEVICE NAMES" +This backend expects device names of the form: +.PP +.RS +.I special +.RE +.PP +Where +.I 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 +.I /dev/video0 +or +.IR /dev/bttv0 . +.SH CONFIGURATION +The contents of the +.I 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: +.PP +.RS +/dev/bttv0 +.br +# this is a comment +.br +/dev/video3 +.RE +.SH FILES +.TP +.I /etc/sane.d/v4l.conf +The backend configuration file (see also description of +.B SANE_CONFIG_DIR +below). +.TP +.I /usr/lib64/sane/libsane\-v4l.a +The static library implementing this backend. +.TP +.I /usr/lib64/sane/libsane\-v4l.so +The shared library implementing this backend (present on systems that +support dynamic loading). +.SH ENVIRONMENT +.TP +.B SANE_CONFIG_DIR +This environment variable specifies the list of directories that may +contain the configuration file. On *NIX systems, 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 +.IR /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 +.B SANE_CONFIG_DIR +to "/tmp/config:" would result in directories +.IR tmp/config , +.IR . , +and +.I /etc/sane.d +being searched (in this order). +.TP +.B SANE_DEBUG_V4L +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. +.SH AUTHOR +Juergen G. Schimmer, Henning Meier-Geinitz + +.SH BUGS: +If more than one video card is present, a crash may occur. Frequency and geometry +selection is missing. +.br +Send bug reports to the SANE mailing list: +.IR sane\-devel@alioth-lists.debian.net . +You must be subscribed to the list to send mail.
