What is libdc1394?
libdc1394 is a library that provides a complete high level application programming interface (API) for developers who wish to control IEEE 1394 based cameras that conform to the 1394-based Digital Camera Specifications (also known as the IIDC or DCAM Specifications). The library is currently the only one to run on all three major platforms (Linux, Mac OSX and Windows). On Linux, both the legacy drivers (raw1394/video1394) and the new 'juju' stack (firewire-ohci) are supported and auto-detected.
libdc1394 provides a complete API that includes camera detection (hotplug coming soon), broadcast commands, bus ressource management (basic), full feature controls (including absolute values), memory channels, external and software trigger, support for all video modes (including 16bit modes and 1394B modes at 800Mb/s), video capture using DMA and full Format_7 control. Moreover, libdc1394 also includes a number extras such as the support of vendor specific features for Allied Vision Technologies (AVT), Basler and PixelInk. The library also includes video conversion tools such as color space conversion (YUV, RGB, MONO, etc...) and the demosaicing of Bayer color pattern images (with 8 different algorithms and including 16bit modes). All these features in combination with the multi-platform compatibility makes libdc1394 the most versatile and performant SDK for IIDC cameras. Moreover, it's open source (license: LGPL) and it's free! Several examples are also provided to put you quickly on the right tracks.
The QImaging CCD family of scientific cameras are designed with solutions for electrophysiology, long stare, color imaging, documentation and live cell imaging. Software All cameras are controllable with the PVCAM driver and supported in Ocular software. Laptops and netbooks:: thinkpad s series laptops:: thinkpad s440contentdetail - Lenovo Support US.
libdc1394 works with every camera that follows the IIDC standard, which is about 500 models. Check the IEEE1394 Digital Camera List for more information.
The libdc1394 project was started by Gord Peters in July 2000. At the time the offer of IIDC cameras was very limited but the advantages of Firewire cameras quickly brought help from other early developers such as Chris Urmson, Dan Dennedy and myself. It was the only API available that was not vendor dependent, and although more existed at the peak of firewire adoption, libdc1394 may be the last one remaining today.
Source code:
For official releases of the source code of libdc1394 you can go to the Sourceforge website. The source code will allow to build the library on Linux, Mac OSX and Windows (the latter via the MinGW compiler). Source packages may be available for your Linux distribution, but these are not maintained by the libdc1394 team.
For bleeding edge code you can also access the project's GIT repository, also on Sourceforge. For example, to get the latest tree type:

Binaries:
Binaries are currently not available on Sourceforge. However, most linux distributions have libdc1394 binaries in their package management system (APT, RPM, YUM, etc...) so you should be able to get them instantly. If you intent to develop code, don't forget to get the '-dev' or '-devel' package which contains the header files, among others.
No binaries are provided for Mac OSX or Windows at this time.
