How to implement background blur in React Native Demo app for IOS

[ashirkhan94]

Hi, Can you give an example for implementing background blur on the amazon-chime-react-native-demo app in ios?. I have not much knowledge of objective c. thanks in advance

Hi I can add the feature request for now, but to unblock you sooner, you might want to translate https://github.com/aws/amazon-chime-sdk-ios/blob/master/guides/background_video_filters.md#implementing-background-blur-in-your-application into objective c.

can you show me the necessary imports. I have integrated AmazonChimeSDKMachineLearning in my app and am importing the necessary headers #import <AmazonChimeSDKMachineLearning/cwt.h> but on creating instances for the classes below I get not found. What else do I need to import. BackgroundBlurVideoFrameProcessor BackgroundReplacementVideoFrameProcessor BackgroundBlurConfiguration

Here's a list of my complete imports

import "NativeMobileSDKBridge.h"

import <AVFoundation/AVFoundation.h>

import "RNVideoViewManager.h"

import <AmazonChimeSDKMedia/AmazonChimeSDKMedia.h>

import "MeetingObservers.h"

import <React/RCTUIManager.h>

import <BackgroundTasks/BackgroundTasks.h>

import <Foundation/Foundation.h>

import <React/RCTBridgeModule.h>

import <React/RCTEventEmitter.h>

import <AmazonChimeSDK/AmazonChimeSDK-Swift.h>

hello @hokyungh, i tried to convert that swift code into obj-c but i could not managed to do it. could you please help me on this?

below you can find my code piece.

RCT_EXPORT_METHOD(setBackgroundBlur:(BOOL)isOn)
{
  logger = [[ConsoleLogger alloc] initWithName:@"NativeMobileSDKBridge" level:LogLevelDEFAULT];

  BackgroundBlurConfiguration *backgroundBlurConfigurations = [[BackgroundBlurConfiguration alloc] initWithLogger:[[ConsoleLogger alloc] initWithName:@"BackgroundBlurProcessor"] blurStrength:BackgroundBlurStrengthLow];
  BackgroundBlurVideoFrameProcessor *backgroundBlurVideoFrameProcessor = [[BackgroundBlurVideoFrameProcessor alloc] initWithBackgroundBlurConfiguration:backgroundBlurConfigurations];

  DefaultCameraCaptureSource *cameraCaptureSource = [[DefaultCameraCaptureSource alloc] initWithLogger:[[ConsoleLogger alloc] initWithName:@"DefaultCameraCaptureSource"]];

  // Add the background blur processor as sink to the video source (e.g. `DefaultCameraCaptureSource`)
  [cameraCaptureSource addVideoSinkWithSink:backgroundBlurVideoFrameProcessor];

  // Use background blur processor as source
  [meetingSession.audioVideo startLocal:backgroundBlurVideoFrameProcessor];
}

as well as i dont know what to import on this bridge file, could you please help?

thank you,
