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
v4l-conf must be installed suid-root.
v4l-conf knows three ways to get the informations:
Query the X-Server using the XF86 DGA extension. This is the default
if the DISPLAY environment variable is set.
Query the framebuffer driver. This is the default if DISPLAY is not
Query the console driver. This is used on mklinux only.
