libraw1394 is the only supported interface to the kernel side raw1394 of
the Linux IEEE-1394 subsystem, which provides direct access to the connected
1394 buses to user space. Through libraw1394/raw1394, applications can directly
send to and receive from other nodes without requiring a kernel driver for the
protocol in question.
This library provides functionality to control any camera that conforms to the
1394-Based Digital Camera Specification (which can be found at
http://www.1394ta.org/Download/Technology/Specifications/Camera120.pdf). It
utilizes the lowlevel functionality provided by libraw1394 to communicate with
the camera.
unicap provides an uniform access to video capture devices. Currently you can access v4l, v4l2, IIDC 1394 ( DCAM ) cameras and video to firewire converters with a single API. New devices can be added via a plugin system
