Build WebRTC Signalling Video & Voice Chat Application for Web/Mobile With MirrorFly

“WebRTC is Popularizing in the Global Market and estimated to grow at a CAGR of 34.37% with rocketing the marketing value of about $ 300 Billion”

With remembering a couple of years ago, creating a web chat application relatively a solid strain for developers. Gradually, the days of utilizing the Flash technology and some licensing codec was fading and the real-time video call chatting landscape was thriving the chat experience to next level of technology.

What does MirrorFly bring Web Real-Time Communication (WebRTC) to you?

MirrorFly, a Superlative Chat app solution delivers an impeccable video/voice call enabled chat application using WebRTC. The emergence and popularity of WebRTC have created immense potentiality of browsers to deliver and tackle peer-to-peer communication through video and audio calls in real-time.

WebRTC was built in a great accordance to the developers which provides the ability to deliver High pixel-rate audio and live video chat apps using Javascript APIs. Though MirrorFly is enabled with in-built WebRTC signaling which in result slashes the pay-for-what-you-use pricing methodologies completely.

Browser & Mobile signaling in WebRTC


Chrome, Firefox, Opera


Android & iOS support


Before getting into the building of a real-time WebRTC video chat app, let us be clear in identifying the functional dependencies to be used to build WebRTC Android/iOS and Web chat App.

Thorough WebRTC Library:

A Complete WebRTC peer-to-peer native code package is required for every developer who wishes to integrate WebRTC for browsers and WebRTC API for Android chat app development.


jQuery is used to handle the event, manipulation and simpler the HTML with the easy to use of APIs that works on several browsers.

Semantic UI CSS:

A framework used to contrive responsive layouts through human-friendly HTML with an elegant CSS framework that works on embellishing the user experience of the Chat Platform.


A Compatible template provides the potential power to build semantic templates in HTML language that brings significant changes in the mobile devices to embed simple WebRTC messaging platform on Android and iOS platforms.

Apart from these dependencies, there are several frameworks and functionalities required to build a chat app for video and voice calling enabled with WebRTC.

Build your own WebRTC Video App with our API

How does Video/Audio Transmission of Chat Application takes place?

webrtc video call androidInitially, both the video and voice call depends on the potentiality of streaming media between two client server connected to each other. Voice Over Internet Protocol (VoIP) is one of the most familiar and trusted standard techniques for voice and live video chat app over the Web.

As we are very much aware that, WebRTC is the significant implementation for streaming of media content from one client-server to another.

  • Signaling
  • STUN Server
  • TURN Server

Signaling – Peer to Peer Connection

Signaling Websockets are used to setup call connection between the client servers. The client connection must adapt to each other by sending messages, data and media over public IP address of both the clients webrtc signaling servers. To get the IP address, We use STUN Server.

STUN Server – Local IP Address

With the use of NAT (Network Address Translation) which provides the local IP address of the device to have peer to peer connection. To make this connection using WebRTC, we need to get the public IP address where STUN Server provides it.

TURN Server – Mediator

This server acts as a mediator to connect both the clients if case peer to peer fails. It sends data from one client to another over signaling process. This methodology works for webRTC video and Audio calls on android/iOS chat app and also for media to create support for the messaging applications.

If you are about to integrate WebRTC into your android/iOS chat app then probably you must have a clear idea on three WebRTC APIs which plays crucial in developing your WebRTC Video/Voice Chat on Android or iOS. Now, let us dig deeper into WebRTC APIs.

A Comprehensive Insight into WebRTC APIs for iOS/Android Chat Application


This allows you to obtain the access over the camera, screen or microphone of the device used by the user. It also provides additional layers as a security where it only allows access if the user is connecting from an (HTTP) secure connection which allows the user to stream their entire media library. This getUserMedia have three parameters namely:

  • A Constraints object
  • A Success Callback method
  • A Failure Callback Method


This webrtc allows the user to communicate directly to have a peer-to-peer connection in order with the transcoding of the media files. It encodes and decodes the entire media content and voice/video chat that is sent to the remote server and from your local machine in receiving your media files.


It helps in transferring the data directly between the two peer users connected in a bi-directional data channel. This also helps in creating a secure connection to send data at a real-time function.

Some of the Highlights that includes in implementing the Interface:

Text Communication:

This allows the user to communicate over text in a real-time chat experience on all the Webrtc audio and video-enabled iOS/Android chat apps.

Voice Communication:

Based on Voice-over IP technology in real-time over the Internet through Chat Application. Low latency is carried to make 1 to 1 or 1 to many webrtc voice chat app connections across all the devices.

Video Communication:

Video Connection helps in making quality webrtc enabled video and audio calls on android/iOS chat apps continuously at low latency. With adaptive bitrate which reduces the complexity of video/audio chat at a high pixel rate.

Bottom Line:

These methodologies are quite bewildering right! To make this more compatible and easier, MirrorFly is inbuilt with all these technologies and features embedded with WebRTC that in resultant to deliver a highly successful WebRTC enabled Voice/Video Chat App that runs seamlessly on iOS/Android and Web browsers.

    I am working on a iOS 10 app with the functionality of p2p video chat just like Skype. I surfing on search engine, there is no libraries for iOS 10 native?

    So, then I decided to go with WebRTC. How can I
    create a video chat native iOS client with the use of these libraries?

      An old version of Internet Explorer & safari(MacOS default) has support in flash only. Now they integrate WebRTC into their browsers. Just update your browsers & let’s try.

      SimpleWebRTC — the WebRTC library
      Semantic UI CSS — an elegant CSS framework
      jQuery — used for selecting elements on the page and event handling.
      Handlebars — a JavaScript templating library, which we’ll use to generate HTML for the messages
      Express — NodeJS server.

      An old one, Using Flash and proprietary codecs. Currently, video call technology has transformed and Flash is no longer required.

      Now WebRTC maintained by top browsers like Google, Mozilla, Opera etc. WebRTC allows you to easily build real-time communication among the browser and is being standardized at the W3C & IETF levels. Using WebRTC, you can build real-time video chat applications that actually work well!

      Yes Alisha, Contus Fly WebRTC Solution supports all cross-platform communications in Android, iOS & Web.

        1. Masi Post author Reply

          That’s only I point out in the previous comment about cross-platform communication. A VOIP functionality purpose is to call from app to landline or application to web etc..

      WebSocket is a protocol which bases on HTTP, so you can send or receive any data via WebSocket. But WebSocket cannot capture video data.

          1. Masi Post author

            Of course, you need a signal server to exchange SDP for WebRTC. You can use WebSocket to build the signal server.

    1. Masi Post author Reply

      Encryption is mandatory for all WebRTC components, and its JavaScript APIs can only be used from secure HTTPS or localhost. Signaling mechanisms aren’t defined by WebRTC standards, so it’s up to you make sure to use secure protocols like a firewall (TURN server).

        1. Masi Post author Reply

          You can use WSS which make WebSocket more secure, of course, you can choose WS to build a WebSocket connection. WebRTC is base on DTLS, so it is more secure. You must use WebRTC via https or WSS, or it rejects to run.

    We are currently, a VoIP service provider. a couple of weeks back I contacted your team. I believe we are now in a position to move forward. am contacting you again for better understanding of your WebRTC capabilities, the MirrorFly services for voice (seems a new service from Contus). In brief, we are seeking solutions/services/technology partners to facilitate our transformation from a pure SIP trunking provider to Cloud communications company. Our primary focus is the voice (We might consider voice/chat later). At the same time, we are focusing on desktop applications (mobile is our secondary priority). We would like to offer our voice service as a integratable service to CRMs, standalone Click2call plugin. We would like to understand your solutions that could compliment and transform our services.

    I want to make an app. This app will be an entertaining app based on video calls with people around the world who want to play the game. I do not want to add too much detail for security reasons. The camera has to be on the player at all times otherwise it will not work. Another thing, is there any way the camera could detect smoke? Is this something that can be made on this site? Please email back. Thank you, Heather

    We are looking for a chat API for our ******** Network App… just to give you a quick overview, we need all the features available in WhatsApp/Telegram and one more in particular that I’ll explain below.

    General features list:

    Private (one-on-one) & Public (group) chats End-to-end Encryption Push Notifications Text & Emojis Media sharing Location features: share real-time live location, specific places location (list & map view) Join/leave group channels Reply/forward messages Mute/unmute notifications Block/unblock users Search within chat Analytics White-label

    Specific feature:

    We noticed that when you share a specific place location in WhatsApp or Telegram, they use the “Foursquare API” to show a list of all the nearby places around you… we want this same feature but instead of sharing a place location, we want to redirect users to a public chat room of that specific place…

    I have a few question about your API. We are developing mobile applications for iOS and Android with Webrtc technology. And we want to integrate it to our app as video call and chat. We have a couple questions. Do you have any log system about the calls which users meet? or Do we record the call as video or audio? Can you give us a demo sample for IOS and Android for seeing useable on our apps? And the last one,

    what is the cost for video call(not conf) with/without chat?

    Thanks in advance.
    Have a good day
