2
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.

## Architecture
83

84
libdc1394 is built around several key components:
85

86
- **System Context**: `dc1394_t` provides the main library context for all operations
87
- **Camera Management**: Discovery, initialization, and control of individual cameras through `dc1394camera_t`
88
- **Video Capture**: Frame-based image acquisition with DMA transfer support
89
- **Feature Control**: Comprehensive camera parameter control (exposure, gain, white balance, etc.)
90
- **Format7 Support**: Scalable image format with ROI (Region of Interest) capabilities
91
- **Image Conversion**: Built-in color space conversion and Bayer demosaicing
92
- **Trigger Control**: External and software trigger support for synchronized capture
