GPAC 是一个为科研和学术领域开发的多媒体的框架，支持 MPEG-4, VRML, X3D, SVG, LASeR 等
GPAC 包括一个多媒体播放器 Osmo4 以及多媒体打包工具 MP4Box
GPAC is cross-platform. It is written in (almost 100% ANSI) C for portability reasons (embedded platforms and DSPs), attempting to keep the memory footprint as low as possible. It is currently running under Windows, Linux, WindowsCE (SmartPhone, PocketPC 2002/2003), Embedded Linux (familiar 8, GPE) and recent SymbianOS systems.
