Detailed Description

Internal (non type-safe) class used by DVBuffer2 to do the actual interfacing with the Firewire (IEE 1394) video hardware.

A wrapper for the libdc1394 library, it assumes that the firewire device is on /dev/video1394/0. Use DVBuffer2 if you want 8-bit greyscale or 24-bit colour.
