FIWARE Stream Oriented Generic Enabler - Overview


The Stream Oriented Generic Enabler (GE) provides a framework devoted to simplify the development of complex interactive multimedia applications through a rich family of APIs and toolboxes. It provides a media server and a set of client APIs making simple the development of advanced video applications for WWW and smartphone platforms. The Stream Oriented GE features include group communications, transcoding, recording, mixing, broadcasting and routing of audiovisual flows. It also provides advanced media processing capabilities involving computer vision, video indexing, augmented reality and speech analysis.

The Stream Oriented GE modular architecture makes simple the integration of third party media processing algorithms (i.e. speech recognition, sentiment analysis, face recognition, etc.), which can be transparently used by application developers as the rest of built-in features.

The Stream Oriented GE’s core element is a Media Server, responsible for media transmission, processing, loading and recording. It is implemented in low level technologies based on GStreamer to optimize the resource consumption. It provides the following features:

  • Networked streaming protocols, including HTTP (working as client and server), RTP and WebRTC.
  • Group communications (MCUs and SFUs functionality) supporting both media mixing and media routing/dispatching.
  • Generic support for computational vision and augmented reality filters. - Media storage supporting writing operations for WebM and MP4 and playing in all formats supported by GStreamer.
  • Automatic media transcodification between any of the codecs supported by GStreamer including VP8, H.264, H.263, AMR, OPUS, Speex, G.711, etc.
