Video Conference

The Video Conference component enables you to integrate reliable video conferences into your web application.

Before we start

Before utilizing the Video Conference, it is essential to initialize the room with a defined name and ID for the participant and the group.

How to use

To add a Video Conference to your web page, you can use the following code:

import { VideoConference } from "@superviz/sdk";

video = new VideoConference({
  avatars: [
    {
      imageUrl: "https://<PATH>",
      model3DUrl: "https://<PATH>"
    }
  ],
  camsOff: false,
  canShowAudienceList: true,
  chatOff: false,
	collaborationMode: {
    enabled: "true",
    position: "right",
    modalPosition: "right",
    initialView: "list"
  },
  defaultAvatars: false,
  defaultToolbar: false,
  devices: {
    audioInput: false,
    audioOutput: false,
    videoInput: false
  },
  enableFollow: false,
  enableGather: false,
  enableGoTo: false,
  language: "en-US",
  locales: [ ],
  screenshareOff: false,
  skipMeetingSettings: false,
  offset: {
    top: 0,
    bottom: 0,
    left: 0,
    right: 0
  },
  participantType: "host"
});

room.addComponent(video);

After being initialized, the Video Conference inserts a SuperViz-enabled iframe into the Document Object Model (DOM). Additionally, if necessary, it sends a request to the browser to consent to access the participant's camera and microphone.

With the necessary permissions consented, the participant can set up the input and output devices, like a camera and microphone, and enter the meeting room.

Properties

The Video Conference properties can be divided into four contexts: layout, presence controls, behavior, and 3D plugins. Please find below the available parameters:

Layout and languages

Here are properties that influence the visual layout and positioning of elements within the component. It includes settings for the offset, camera positioning, and color scheme.

Events

The Video Conference in SuperViz SDK offers a range of events that allow you to monitor and respond to several interactions and changes within the meeting. These events provide valuable insights into participant actions, meeting state transitions, and more.

For a comprehensive understanding of events associated with the Video Conference, please refer to the Video Conference Events documentation. This dedicated resource will provide you with detailed information on subscribing to, handling, and utilizing events specific to this component.

By visiting the component-specific documentation, you'll gain access to insights into events like participant join/leave notifications, meeting state changes, and other event-driven functionalities tailored to the Video Conference.

Callbacks

When using the Video Conference, you can define a range of callbacks to handle specific events and interactions within the meeting. These callbacks allow you to respond to participant actions, meeting state changes, and other event-driven functionalities.

To define a callback, you need to pass a function when creating the Video Conference, as shown in the example below:

const video = new VideoConference({
  callbacks: {
    onToggleMicrophone: () => {},
    onToggleCam: () => {},
    onToggleTranscript: () => {},
    onToggleChat: () => {},
    onToggleScreenShare: () => {},
    onClickHangup: () => {},
    onToggleMeetingSetup: () => {},
  },
});

When you pass a function to the callbacks object, the default behavior of the Video Conference will be overridden by the function you provide. This allows you to customize the behavior of the Video Conference to suit your specific requirements.

For example, when using onToggleChat(), the chat modal will not be displayed when the participant clicks the chat button, as a custom function has been provided by you. To ensure the chat modal is displayed, you need to include the logic to show the chat modal within the function you provide, like so:

const video = new VideoConference({
  callbacks: {
    onToggleChat: () => {
      // Your logic
      video.toggleChat();
    },
  },
});

`onToggleMicrophone`

This callback is triggered when the participant toggles their microphone on or off during the video conference.

If you just need to wrap the default behavior with your custom logic, you can use the toggleMicrophone() method inside the callback function to ensure the default behavior is maintained.

Example:

const video = new VideoConference({
  callbacks: {
    onToggleMicrophone: () => {
      // Your logic
      video.toggleMicrophone();
    },
  },
});

`onToggleCam`

This callback is triggered when the participant toggles their camera on or off during the video conference.

If you just need to wrap the default behavior with your custom logic, you can use the toggleCam() method inside the callback function to ensure the default behavior is maintained.

Example:

const video = new VideoConference({
  callbacks: {
    onToggleCam: () => {
      // Your logic
      video.toggleCam();
    },
  },
});

`onToggleTranscript`

This callback is triggered when the participant toggles the transcript feature on and off during the video conference.

If you just need to wrap the default behavior with your custom logic, you can use the toggleTranscript() method inside the callback function to ensure the default behavior is maintained.

Example:

const video = new VideoConference({
  callbacks: {
    onToggleTranscript: () => {
      // Your logic
      video.toggleTranscript();
    },
  },
});

`onToggleChat`

This callback is triggered when the participant toggles the chat modal on and off during the video conference.

If you just need to wrap the default behavior with your custom logic, you can use the toggleChat() method inside the callback function to ensure the default behavior is maintained.

Example:

const video = new VideoConference({
  callbacks: {
    onToggleChat: () => {
      // Your logic
      video.toggleChat();
    },
  },
});

`onToggleScreenShare`

This callback is triggered when the participant toggles the screen-sharing feature on and off during the video conference.

If you just need to wrap the default behavior with your custom logic, you can use the toggleScreenShare() method inside the callback function to ensure the default behavior is maintained.

Example:

const video = new VideoConference({
  callbacks: {
    onToggleScreenShare: () => {
      // Your logic
      video.toggleScreenShare();
    },
  },
});

`onClickHangup`

This callback is triggered when the participant leaves the video conference.

Example:

const video = new VideoConference({
  callbacks: {
    onClickHangup: () => {
      // Your logic
      video.hangUp();
    },
  },
});

`onToggleMeetingSetup`

This callback is triggered when the participant clicks the settings button in the video conference.

If you just need to wrap the default behavior with your custom logic, you can use the toggleMeetingSetup() method inside the callback function to ensure the default behavior is maintained.

Example:

const video = new VideoConference({
  callbacks: {
    onToggleMeetingSetup: () => {
      // Your logic
      video.toggleMeetingSetup();
    },
  },
});

Methods

`subscribe()`

The subscribe method allows you to register your application to listen for specific events within the Video Conference. By subscribing to events, you can capture and respond to important interactions or changes that occur during a video conference session.
