Kurento: The Webrtc Modular Media Server

In this paper we introduce Kurento Media Server: an open source WebRTC Media Server providing a toolbox of capabilities which include group communications, recording, routing, transcoding and mixing. Kurento supports a large number of media protocols such as WebRTC, plain RTP, RTSP or HTTP and bunch of codecs including VP8, VP9, H.264, H.263, OPUS, Speex, PCM or AMR. Kurento Media Server is based on a modular architecture, which makes it possible for developers to extend and customize its native capabilities with advanced media processing features such as computer vision, augmented reality or speech analysis. Kurento is ideal for WWW developers who find natural programming with its Java and JavaScript APIs following the traditional three tiered WWW development model.
