GPAC Project on Advanced Content (GPAC, a recursive acronym) is an implementation of the MPEG-4 Systems standard written in ANSI C. GPAC provides tools for media playback, vector graphics and 3D rendering, MPEG-4 authoring and distribution.[5]
GPAC provides three sets of tools based on a core library called libgpac:
- A multimedia player, cross-platform command-line based MP4Client or with a GUI Osmo4
- A multimedia packager, MP4Box
- Some server tools, around multiplexing and streaming (under development).
GPAC is cross-platform. It is written in (almost 100% ANSI) C for portability reasons, attempting to keep the memory footprint as low as possible. It is currently running under Windows, Linux, Solaris, Windows CE (SmartPhone, PocketPC 2002/2003), iOS, Android, Embedded Linux (familiar 8, GPE) and recent Symbian OS systems.
The project is intended for a wide audience ranging from end-users or content creators with development skills who want to experiment the new standards for interactive technologies or want to convert files for mobile devices, to developers who need players and/or server for multimedia streaming applications.
The GPAC framework is being developed at École nationale supérieure des télécommunications (ENST) as part of research work on digital media.
