OpenLibraries 0.3.0 is out

 

LONDON—The Jahshaka Project (www.jahshaka.org <http://www.jahshaka.org/> )
today announces the availability of the OpenLibraries 0.3.0
(www.openlibraries.org <http://www.openlibraries.org/> ), a powerful,
cross-platform set of C++ libraries that provide developers with key
components to create, test and deploy rich media applications. Currently in
pre-alpha phase, the OpenLibraries support Linux, OS X and Windows operating
systems, and are licensed under the GNU LGPL agreement.  

The OpenLibraries were created to support the Jahshaka Project, a
collaborative effort to develop an open source, real-time editing and visual
effects application, by providing it with a solid, multimedia framework. The
libraries have a unified plugin architecture and can be used for the
development of nonlinear editing applications, 2D and 3D compositing
applications, 2D and 3D players, and image processing applications. Core
modules comprise asset management, image management, 3D object management,
media management, image processing, network management and plugin
development.

“OpenLibraries offers a  core set of libraries and an asset system that is
easy to use,” said Gonçalo de Carvalho, Lead Developer of Open Libraries.
“Although it is new technology, the architecture has been established for
nearly two years and was developed from the start as open source.”

The alpha version includes working implementations of the libraries’ object,
media and image modules. Additionally, the libraries’ plugin module features
a stable architecture for feature abstraction and development. Other key
features include support for high-dynamic range images and 3D. The media
module includes support for media and image sequence playback, with and
without cache. 

OpenLibraries is the technology behind a professional-quality player called
Jahplayer. “Our goal is to create a set of libraries with a totally free
architecture,” said Gonçalo de Carvalho, lead developer of OpenLibraries.
“It will ultimately be a robust, professional-grade, full-featured,
open-source toolkit rivaling anything that is available commercially.”

Please visit www.openlibraries <http://www.openlibraries/>  for more
information and to download the binaries. Please visit www.jahshaka.org
<http://www.jahshaka.org/>  for Jahshaka and Jahplayer, which are built on
the libraries.
