NAME

       v4l-conf -  configure a video4linux driver

SYNOPSIS

       v4l-conf [ options ]

DESCRIPTION

       v4l-conf  is  a  small  helper tool.  It figures out the video mode and
       framebuffer base  address  of  the  graphics  board  and  configures  a
       video4linux driver like bttv.  This is needed for drivers which can DMA
       the video over PCI directly into the video memory.

       Usually it is not required  to  use  v4l-conf  manually,  xawtv(1)  and
       fbtv(1)  run  it  automatically  at  startup.   It  might be useful for
       trouble-shooting.  v4l-conf must be installed suid-root.

       v4l-conf knows three ways to get the informations:

        * Query the X-Server using  the  XF86  DGA  extention.   This  is  the
          default if the DISPLAY environment variable is set.

        * Query the framebuffer driver.  This is the default if DISPLAY is not
          set.

        * Query the console driver.  This is used on mklinux only.

OPTIONS

       -h  Print a short description of all command line options.

       -q  Be quiet.

       -d dpy
           Use the X11 display dpy to get the parameters.

       -f  Use the framebuffer driver to get the parameters.

       -c device
           Set the video4linux device.

       -b n
           enforce n bpp color depth.  Works for switching between  15/16  and
           24/32 bpp.

       -s n
           Shift the video display by n bytes.

       -a adr
           Set  framebuffer  address to adr.  The value should be specified in
           hex.  This option is allowed for root only.   You  can’t  overwrite
           the  autodetected  value,  this switch is only useful if autodetect
           doesn’t work because the X-Server lacks DGA support.  You  can  put
           this   into  /etc/conf.modules,  as  "post-install  bttv  ..."  for
           example.

BUGS

       Hope I havn’t any security flaws in there.  If you find one, drop me  a
       note.  Mails with patches are preferred :-)
