Web DevelopmentCreating your own streaming app with WebRTC

Introduction

In today's world, video communication has become an essential part of our personal and professional lives. Whether it's virtual meetings with colleagues, online classes, or catching up with friends and family, video communication tools like Google Meets, Teams, or Zoom have become ubiquitous. But have you ever considered creating your custom video communication platform that caters to your specific needs?

WebRTC as solution

The answer for you may be WebRTC. WebRTC is a free and open-source project that provides real-time communication capabilities to web browsers and mobile applications through simple APIs. It enables peer-to-peer communication between browsers and mobile devices, as well as between browsers and servers. WebRTC offers a variety of features that are essential for video communication, including audio and video codecs, network protocols, and security mechanisms. It also provides APIs for handling user media, creating peer-to-peer connections, and controlling media streams. WebRTC is supported by all major browsers, including Chrome, Firefox, Safari, and Edge, as well as by Android and iOS devices. It may solve your implementation issues, however, you must remember that it still will be a quite complex thing to implement. 

In Mobile Reality we have analyzed dozens of potential ideas from our clients and they still are more willing to choose plug-n-play tools like Castr or Boxcast. 

WebRTC difficulties

You may ask yourself: “Where is the problem when you can do it with WebRTC?”. That’s a good question. The answer is simple. WebRTC comes with simple methods which can be used with your browsers (you can check if it’s supported here) but it doesn’t come with the whole infrastructure needed for this undertaking. It’s vital to understand the costs behind it. And you can ask again: “What kind of costs? WebRTC is designed to do p2p calls so it relies on the connection of its peers”. And again it’s partially true but how would you connect these peers with yourself? At the first glance, it looks like a cost-free solution but it’s not. If you want to have real products for your customers you need to rely on your infrastructure or pay for using someone else. A good example of such a tool is Meltered. 

Setting up steps

Okay so let me show the needed things for setting up your communicator:

1. You need a server and database for your application so Backend implementation

The server is responsible for handling requests and responses between the client side and the database, which stores data used by the application.

2. You need your STUN server

This is a server used for NAT traversal, which allows devices on a private network to communicate with devices on the public internet.

3. You need your TURN server

This is a server used for relaying data between clients in the case that a direct peer-to-peer connection cannot be established.

4. You need WebRTC for your application so Frontend implementation

Here is a good visualization of what I’m talking about:

Conclusion 

Every point is related to costs that need to be covered. These costs may include expenses related to purchasing equipment, hiring staff, acquiring software, and other resources necessary for the project. Additionally, after the initial implementation of a project or business operation, there may be monthly fixed costs associated with maintaining and operating these resources. 

However, some clients may not be fully aware of the financial implications of starting a new project or implementing a new business operation. As a result, they may prefer to use established and tested tools and resources that have a proven track record of success, in order to minimize costs and reduce risks.
