UniMRCP API Reference

1.1.0

Introduction

UniMRCP is an open source project compliant with the IETF RFC6787 (MRCPv2) and RFC4463 (MRCPv1) specifications. The project encapsulates SIP, RTSP, SDP, MRCPv2, and RTP/RTCP stacks and provides an MRCP version independent API to client user applications. It also defines a plugin interface for integration of media resource engines into the UniMRCP server.

Source Tree Structure

Libraries

apr-toolkit - Set of utilities built on top of the APR and APR-util libraries (task abstraction, logging, etc).
mpf - Media processing framework.
mrcp - Implementation of MRCP basics (message, parser, resources).
mrcpv2-transport - Implementation of the MRCPv2 transport layer.
mrcp-signaling - Abstract MRCP signaling (session management) interface.
mrcp-engine - Abstract resource engine interface.
mrcp-client - Implementation of an MRCP client stack based on the abstract signaling interface.
mrcp-server - Implementation of an MRCP server stack based on the abstract signaling and engine interfaces.
uni-rtsp - Implementation of a minimal RTSP stack required for MRCPv1.

Modules

mrcp-sofiasip - Implementation of the abstract signaling interface using the SofiaSIP library.
mrcp-unirtsp - Implementation of the abstract signaling interface using the UniRTSP library.

Plugins
