What are the servers required for video calling?

WebRTC is a well-known tech in video chat application making from a technology standpoint. It’s an open-source internet protocol that helps users make videos in real-time using straightforward APIs. The great tech is used to establish and perform a peer-to-peer connection; without the guidance of a top-notch web server from a third party. This is how WebRTC will keep on submitting media content. In brief, WebRTC can effectively be used together with four APIs, which are the following:

  • RTC DataChannel
    It offers a peer-to-peer communication network for data generalisation.
  • MediaStream
    This one allows chatting between clients using either a video camera or a microphone.
  • OpenTOK
    Although it’s not a specific API, an open-source library and PaaS platform can be used to authorise cross-platform video chats.
  • RTCPeerConnection
    This API is liable for the protection of video chats, as it authorizes video and audio data transfer with top-notch access control and encryption support.

Where can we use WebRTC technology?

A wide array of fascinating use cases exist for WebRTC. The best utilisations are shown below:

  • Broadcasting
    WebRTC can be utilised to distribute single-way media transmissions, for example, speeches, videos, podcasts, and concerts. In addition, users can acquire a real-time solution, such as attendance information, with the help of a solution, PubNub.
  • Audio Calling
    The audio and video in WebRTC work seamlessly by using codecs, which are well-known algorithms used to compress and decompress audio and video data. Moreover, Ficode has previous experience integrating audio calling in web and mobile applications. That’s why with the help of WebRTC, our developers can build the best video chat app.
  • Share screen
    Sharing screen is another use case of WebRTC technology, which helps you get explicit notions about the work and its outcomes. After Ficode’s involvement in making seamless video chat apps with WebRTC technology for your business, you can see your sales reps grow.


The most significant benefits of choosing Node.Js for real-time video chat application development projects are the following:

  • A Node.Js framework is renowned for its event-driven competency, making it hassle-free for Ficode’s web developers to track I/O bound tasks. Also, its streams are UNIX-based and that’s why the framework can be read clearly and decode the input from its source and send it back to its original destination.
  • By selecting Node.JS to create a video chat app, the developers can ensure straightforward data transfer between the server and client. Also, this server can make sure data readability and transferability between the server and client.

Where can we use Node.JS technology?

Following are the leading areas where Node.JS proves itself an ideal tech partner:

  • Data streaming applications
  • Single page applications
  • Data Intensive Real-time Applications (DIRT)
  • JSON APIs based apps

How does Ficode help create a video chat application?

Video calls are similar to ordinary phone calls, where you can see that person and hear his/her voice. Most video calling apps frequently provide additional features, such as video group calling and video sharing facilities. The best examples of video chat applications are:

  • Video calling apps: FaceTime, Facebook Messenger, and Whatsapp
  • Conferencing apps: Skype, Zoom, and Hangouts
  • Entertaining apps: Rave, Houseparty, and Discord
