In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
This option adds support for the video1394 device files which enable
isochronous communication of user programs with IEEE 1394 devices,
especially video capture or export. This interface is used by all
libdc1394 based programs and by several other programs, in addition to
the raw1394 interface. It is generally not required for DV capture.

To compile this driver as a module, say M here: the module will be
called video1394.

video1394 is superseded by the newer firewire-core driver. See for
further information on how to switch to the new FireWire drivers.
