Embed Video Call on Website with Prebuilt SDK

#javascript #webdev #programming #webrtc

This article will introduce how to embed Video Call into your website using the Prebuilt SDK with two lines of code.

Video call function: how to implement it?

Information transmission has evolved from text to pictures and now to video.

Video calls are becoming more and more a necessary feature for applications.

From IM, dating, and meetings to live streaming and education, applications in all walks of life will integrate the video call function.

For this function to be implemented, If you don't use the prebuilt SDK, there are some complex tasks to accomplish. For instance:

Interactive interface development - Although the video call has only one page, there are various interactive buttons; each button has multiple states, that can be switched in different ways, rendering the interactive interface quite hard to handle.
Audio and video management - Audio and video management require a lot of testing and verification to ensure the stability of calls, such as different platforms, devices, system versions, and network environments which all need to be targeted. It's a time-consuming effort.
User permissions, call status, and other business-related - includes camera and microphone switch permissions, call permissions, call duration, hang up, waiting, and call status. These states seem simple, but since each of them has multiple modification paths, the logic underpinning a correct state is complex. For example, if the call is 'hung up', there can be 'active hang-up', 'passive hang-up', network 'error hang-up', 'insufficient quota', etc.

Not every team can invest a lot of workforce in solving this heavy R&D work, yet Video Call is an essential product function. The solution is to use the Prebuilt SDK to implement the Video Call function quickly.

What is the Prebuilt SDK?

Video Call Prebuilt SDK sorts out the personalized interface and interaction in Video Calls by:

abstracting the standard functions and logic in Video Call
encapsulating these standardized functions and logic in the Prebuilt SDK.
integrating personalized interfaces and interactions into configuration items. Users only need two lines of code to implement the Video Call function; personalized interface and interaction can be achieved through item configuration.

ZEGOCLOUD Prebuilt web SDK

ZEGOCLOUD Prebuilt SDK is a set of standard solutions sorted out from the integration process of thousands of customers in Video Call customers.

Two lines of code complete the access

ZEGOCLOUD's prebuilt SDK only needs two lines of code to complete SDK access.

Call the init interface to complete the SDK initialization.
Call the joinRoom interface to join the audio and video call.

        leftScreen: true; // leave the room page, default is
  });
