libdc1394

libdc1394 provides Java bindings for the libdc1394 library, which offers high-level API for controlling IEEE 1394 (FireWire) digital cameras following IIDC/DCAM specifications. The library enables cross-platform camera management and control, supporting approximately 500 camera models with features including camera detection, comprehensive feature controls, multiple video mode support, high-performance video capture using DMA, color space conversion capabilities, and demosaicing of Bayer color pattern images.

import java.io.*;

// Initialize libdc1394 system

Architecture

libdc1394 is built around several key components:

System Context: dc1394_t provides the main library context for all operations
Camera Management: Discovery, initialization, and control of individual cameras through dc1394camera_t
Video Capture: Frame-based image acquisition with DMA transfer support
Feature Control: Comprehensive camera parameter control (exposure, gain, white balance, etc.)
Format7 Support: Scalable image format with ROI (Region of Interest) capabilities
Image Conversion: Built-in color space conversion and Bayer demosaicing
Trigger Control: External and software trigger support for synchronized capture
