Comprehensive Typescript implementation of Adobe's Real Time Messaging Protocol (RTMP) using Bitstream

Motivation

This library is intended to provide an approachable and comprehensive RTMP implementation for Node.js using Typescript.
It uses similar concepts to those of Adobe Flash / Flash Media Server / Flex in exposing RTMP to users. Supports AMF v0
and v3 via @astronautlabs/amf

Installation

``
npm i @astronautlabs/rtmp
`

Examples

Server

`typescript
import 'reflect-metadata';
import 'source-map-support/register';

import { Socket } from 'net';
import * as RTMP from '@astronautlabs/rtmp';

class MyServer extends RTMP.Server {
protected createSession(socket: Socket): RTMP.Session {
return new MySession(this, socket);
}
}

class MySession extends RTMP.Session {
protected createStream(id: number): RTMP.ServerMediaStream {
return new MyStream(this, id);
}
}

class MyStream extends RTMP.ServerMediaStream {
play(streamName: string, start: number, duration: number, reset: boolean): void {
// Client wants to receive this stream.

this.notifyBegin();

this.sendVideo(Buffer.from([ ... ]));
this.sendAudio(Buffer.from([ ... ]));
}

publish(streamName : string) {
// Client is publishing this stream
}

receiveVideo(data : Uint8Array) {
// Do something with the video packets
}

receiveAudio(data : Uint8Array) {
// Do something with the audio packets
}
}

let server = new MyServer();
server.listen();
`

Custom RPC

`typescript
import 'reflect-metadata';
import 'source-map-support/register';

import { Socket } from 'net';
import * as RTMP from '.';

class MyServer extends RTMP.Server {
protected createSession(socket: Socket): RTMP.Session {
return new MySession(this, socket);
}
}

class MySession extends RTMP.Session {
protected createStream(id: number): RTMP.ServerMediaStream {
return new MyStream(this, id);
}
}

class MyStream extends RTMP.ServerMediaStream {

/**
* Mark any method with @RPC() to expose it as an RTMP command.
* Here the command 'customMethod' gets mapped to this method, with
* its parameters automatically converted from AMF0/3 to the appropriate
* Javascript types, and the return value being sent back in a "_result"
* response. If an exception is thrown, an "_error" response is sent back with
* a summary of the error.
*/
@RPC() customMethod(foo : string, bar : number[]) {
return { message: 'All done!' };
}

play(streamName: string, start: number, duration: number, reset: boolean): void {
console.log(play('${streamName}', ${start}, ${duration}, ${reset}));
super.play(streamName, start, duration, reset);
}
}

let server = new MyServer();
server.listen();
