libavg is a high-level development platform for media-centric applications. libavg allows programmers, media artists and designers to quickly develop media applications. It uses python as scripting language and is written in high-speed C++. The project has been under constant development since it's inception in 2003. Since 2007, development is being sponsored by Archimedes Exhibitions, which uses libavg for it's exhibits. libavg has a clear and consistent interface and is easy to learn and use. It delivers professional-quality graphics by default. Above all, however, libavg is fast. The C++ core is written with performance in mind, all graphics processing is hardware-accelerated through OpenGL, and GPU Shaders are used to accelerate critical parts like video decoding, compositing and visual effects.
