Camera / Mic Indicator is on when the camera was initialising user routed to different page.

I am using the below code to show the preview video before joining the call, but when the camera was initialising if the user navigates to a different page then the LED light indicator keeps on running on different route also. It should get closed as soon as the user leaves the page.

Previe Video Code

import {
	ConsoleLogger,
	DefaultDeviceController,
	LogLevel,
} from "amazon-chime-sdk-js";

const logger = new ConsoleLogger("sdk", LogLevel.INFO);
const deviceController = new DefaultDeviceController(logger, {
enableWebAudio: true,
});

const previewVideo = async () => {
  const audioList = await deviceController.listAudioInputDevices();
  const deviceList = await deviceController.listVideoInputDevices();
  await deviceController.chooseVideoInputDevice(deviceList[0]?.deviceId);
  deviceController.startVideoPreviewForVideoInput(videoElement.current);
};

Render: <video ref={videoElement}></video>

Thanks for reporting the issue. Yes, if JS SDK has already called getUserMedia as part of await deviceController.chooseVideoInputDevice(deviceList[0]?.deviceId); then the LED will go ON and any re-direction would not stop it automatically.

To turn the LED off, you have to follow this FAQ.

You also have to check for user re-direction though. You can use PageVisibility API to this and do the following:

// Handle page visibility change
document.addEventListener(visibilityChange, handleVisibilityChange, false);

async function handleVisibilityChange() {
  if (document.visibilityState === 'hidden') {
    // Select no video device (releases any previously selected device)
    await meetingSession.audioVideo.chooseVideoInputDevice(null);
    
    // Stop a video preview that was previously started (before session starts)
    meetingSession.audioVideo.stopVideoPreviewForVideoInput(previewVideoElement);
    
    // Stop the meeting session (audio and video)
    meetingSession.audioVideo.stop();
  }
}

Please let me know if this works for you or you have more questions.
