## Overview

This repository is a collection of WebRTC experiments, browser libraries, and demos rather than one application. Its common user-to-result pattern is to select or capture media, then record, mix, share, or connect it; signaling supports peer communication where needed. The map preserves the README’s major library capabilities and treats them as independent product branches. The README documents several behaviors, but source excerpts are limited, so wiring is shown only where documented or sampled code supports it.

Main entry points: [`RTCMultiConnection/dev/RTCMultiConnection.js`](https://github.com/muaz-khan/webrtc-experiment/blob/master/RTCMultiConnection/dev/RTCMultiConnection.js) (RTCMultiConnection), [`RecordRTC/RecordRTC.js`](https://github.com/muaz-khan/webrtc-experiment/blob/master/RecordRTC/RecordRTC.js) (RecordRTC), [`DataChannel/DataChannel.js`](https://github.com/muaz-khan/webrtc-experiment/blob/master/DataChannel/DataChannel.js) (DataChannel), [`MultiStreamsMixer/MultiStreamsMixer.js`](https://github.com/muaz-khan/webrtc-experiment/blob/master/MultiStreamsMixer/MultiStreamsMixer.js) (MultiStreamsMixer)
