Virtual Background(BETA) - Flutter

Virtual backgrounds let you replace your real background during video calls or meetings with a digital image or video. This can be useful for:

• Privacy: Hide your messy room or anything you don't want others to see.

• Focus: Minimize distractions and keep the focus on the conversation.

• Fun: Liven up the call with a cool background theme.

note

Virtual background is currently in BETA and may not perform optimally on certain devices or with custom tracks that have high resolutions.

Virtual Background using VideoSDKMediaEffects plugin

The VideoSDKMediaEffects plugin enables the integration of sophisticated virtual background effects within your video applications.

Apply Virtual Background

• The applyVirtualBackground() method from the VideoSDKMediaEffects plugin allows users to dynamically change the video background during a live session. By passing a URI of the desired background image, this method seamlessly integrates the virtual background into the video stream.

Change Virtual Background

• The changeVirtualBackground() method from the VideoSDKMediaEffects plugin enables users to effortlessly switch their current virtual background to a new image. This functionality allows for dynamic customization and enhances the user's video experience by providing the ability to update their background on the fly. By passing a URI of the new background image, this method seamlessly integrates the new virtual background into the video stream.

Remove Virtual Background

• The removeVirtualBackground() method from the VideoSDKMediaEffects plugin provides users with a convenient way to revert their video background to its original state, removing any previously applied virtual background. This functionality ensures flexibility for users to switch between virtual and real backgrounds as needed.

Example Code:

import 'package:flutter/material.dart';
import 'package:videosdk/videosdk.dart';
//Import the plugin
import 'package:videosdk_media_effects/videosdk_media_effects.dart';

class MeetingScreen extends StatefulWidget {
  //Existing configuration
}

class _MeetingScreenState extends State<MeetingScreen> {
  late Room _room;

  @override
  void initState() {
    //Existing configuration
  }

  @override
  Widget build(BuildContext context) {
    return Column(
      children:[
        //To Apply Virtual Background
        ElevatedButton(
          onPressed:(){
            Uri backgroundImageURI = Uri.parse("https://cdn.videosdk.live/virtual-background/cloud.jpeg");
            VideosdkMediaEffects.applyVirtualBackground(backgroundSource: backgroundImageURI);
          },
          child: const Text("Apply Virtual Background"),

          onPressed:(){
            Uri newBackgroundImageURI = Uri.parse("https://cdn.videosdk.live/virtual-background/san-fran.jpeg");
            VideosdkMediaEffects.changeVirtualBackground(backgroundSource: newBackgroundImageURI);
          },
          child: const Text("Change Virtual Background"),
        ),
        //To Remove Virtual Background
        ElevatedButton(
          onPressed:(){
            VideosdkMediaEffects.removeVirtualBackground();
          },
