parsing

import { parse } from "@webrtc-toolbox/sdp-parser";

const sessionDescription = parse(sdp);

printing

import { print } from "@webrtc-toolbox/sdp-parser";

const sdp = print(sessionDescription);

munging

import { parse, print } from "@webrtc-toolbox/sdp-parser";

const sessionDescription = parse(sdp);

sessionDescription.mediaDescription[0].attributes.ssrcs.push({
  ssrcId: "1024",
  attributeName: "label",
  attributeValue: "oTwikEfJsdv0",
});

const mungedSdp = print(sessionDescription);

roadmap

• Better error report while parsing
• Performance improvements
