WebRTC Semantic SDP

Minimal SDP information semantic data model and parsing tools.

Motivation

Have you ever tried to mangle or process an SDP and got stuck about how to you change the information instead of what information do you want to access?

This project provies an abstraction layer on top of SDP that allows to acces and modify the information semantically, that is, it stores the SDP information and their relationships and allows you to get free of the acutal SDP semantics.

As it is meant to be used on WebRTC to WebRTC scenarios, so some SDP information can be safelly ignored, allowing to provide a simple and intuitive API.

Both Unified and Plan B are currently supported

Assumptions

We assume that:

Bundle is used
Trickle ICE or ICE lite is used
DTLS is used
RTCP mux is used

For the future

If you think it further exchanging the SDP information is all that it is needed to perform a peer to peer SDP exchange, so the intention is to provide serialization functions to be able to use this over the wire and only parse/serialize it on the endpoints or server side.

Note also that there is some similarity ORTC RTP parameters, but well done 😉

Install

npm i --save semantic-sdp

Usage

const SemanticSDP = require('semantic-sdp');
