After unsubscribe, seems camera is still active

[TLKG]

To utilize it:

import {WebcamImage, WebcamInitError, WebcamUtil} from 'ngx-webcam';
export class MyComponent implements OnInit, OnDestroy
{
...
private nextWebcam: Subject<boolean|string> = new Subject<boolean|string>();
constructor() { this.openWebCam();}
public get nextWebcamObservable(): Observable<boolean|string> 
    {
        return this.nextWebcam.asObservable();
    }
ngOnDestroy() 
{ 
  this.nextWebcam.unsubscribe(); 
...
}
}

After exiting the page, still shows

How to completely cancel this camera service?

"ngx-webcam": "^0.3.2"
"@angular/core": "^12.1.4"

Hi, not sure why first PR is waiting for such a long time. I faced that issue, too and executing this.mediaStream.removeTrack(track); really helps.

Unfortunately it does not resolve the issue always (there still might be some delay of turning camera off). What worked in my case is to call this.nextWebcam.complete(); on the code that closes camera connection (triggered in closeModal method in my case).

Just leaving my 2 cents on that for future users..PR created here: https://github.com/basst314/ngx-webcam/pull/155/commits/f5b237293b6e79299ec62a6ff2dabc762e963385
