rtp.js

RTP stack for Node.js and browser written in TypeScript. rtp.js provides with an API to parse, generate and modify RTP and RTCP packets.

Installation

npm install rtp.js

Usage

• API documentation

• All RTP and RTCP classes, types and packet related helpers are exported by the packets module:

  import {
  	isRtp,
  	isRtcp,
  	RtpPacket,
  	CompoundPacket,
  	ReceiverReportPacket,
  	SenderReportPacket,
  	ReceptionReport,
  	ByePacket,
  	SdesPacket,
  	NackPacket,
  	SrReqPacket,
  	EcnPacket,
  	PliPacket,
  	SliPacket,
  	RpsiPacket,
  	XrPacket,
  	ExtendedJitterReportsPacket,
  	GenericPacket,
  	// etc.
  } from 'rtp.js/packets';
  
  const rtpPacket = new RtpPacket();

• The utils module exports some generic helpers and utilities:

  import {
  	padTo4Bytes,
  	nodeBufferToDataView,
  	dataViewToNodeBuffer,
  	nodeBufferToArrayBuffer,
  	arrayBufferToNodeBuffer,
  	numericArrayToDataView,
  	numberToDataView,
  	dataViewToString,
  	arrayBufferToString,
  	stringToDataView,
  	getStringByteLength,
  	// etc.
  } from 'rtp.js/utils';
  
  const view = stringToDataView('fooœæ€ñ#¢∞Ω©bar');

• CommonJS is also supported:

  const { RtpPacket /* etc. */ } = require('rtp.js/packets');
  const { padTo4Bytes /* etc. */ } = require('rtp.js/utils');

• Single entry point ("main" or "module" entries in package.json) is also supported for backwards compatibility:

  // Using ESM:
  import { packets as rtpJsPackets, utils as rtpJsUtils } from 'rtp.js';
  
  // Using CJS:
  const { packets: rtpJsPackets, utils: rtpJsUtils } = require('rtp.js');
  
  const { RtpPacket /* etc. */ } = rtpJsPackets;
  const { padTo4Bytes /* etc. */ } = rtpJsUtils;

Note about TypeScript

rtp.js is written in TypeScript with module: NodeNext, meaning that TypeScript projects that want to import rtp.js using its exposed entry points ("rtp.js/packets" and "rtp.js/utils") must have moduleResolution set to "node16", 'NodeNext" or "bundler" in their tsconfig.json file.
