GPAC is a multimedia framework based on the MPEG4 systems standard. It aims to integrate as many "rich media" technologies as possible. It already supports MPEG-4 BIFS, SVG, MPEG-4 LASeR, VRML, and X3D presentations, many audio/video codecs and formats, RTP/RTSP streaming, MPEG-2 TS broadcast, ISO File format and HTTP Streaming (MPEG-DASH and HLS). GPAC provides both a player (Osmo4 / MP4Client) and command line tools (MP4Box and MP42TS).
