Please describe your bug.

I am encountering an issue with FaceLivenessDetectorCore while implementing face liveness detection for users. After the face liveness process is completed, the camera light remains on, indicating that the camera is not being released properly.

It seems that FaceLivenessDetectorCore continues to access the user's camera permissions and does not release the camera resource once the face liveness process is finished.

What's the expected behaviour?

After the face liveness process is completed, the camera should be released, and the camera light should turn off.

Help us reproduce the bug!

1. Run FaceLivenessDetectorCore independently, and it will request camera permissions.
2. Complete the face liveness check.
3. After the process is completed, the camera light remains on.

Code Snippet

import { FaceLivenessDetectorCore } from '@aws-amplify/ui-react-liveness'

<FaceLivenessDetectorCore
    sessionId={sessionId}
    region={AWS_AMPLIFY_REGION}
    onAnalysisComplete={handleAnalysisComplete}
    onError={handleLivenessComponentError}
    config={getLivenessConfig()}
/>

Hello, @rishabhgupta1234 and thank you for opening this issue. We'll investigate this further and reproduce on our side, but for further clarity are we talking about the webcam light that shows the camera is in use? Can you clarify what version and OS you're using as well?

Hi @cwomack thanks for replying

Please find the details below

1. Yes, about webcam light
2. @aws-amplify/ui-react-liveness version is 3.1.1
3. Ubuntu 24.04.1

@rishabhgupta1234 What are you rendering once the analysis is complete? It's the responsibility of the developer to render another screen using onAnalysisComplete, at which point the video will no longer be rendered in the DOM.
