Error in console

Hello! I need help with getting video stream from camera.

[Angular 6] Problem description:

The error is invoked only in Safari webrowser (updated to the latest version) and only on Mac. When we're trying to get video stream from camera through method navigator.mediaDevices.getUserMedia({video: true}, the webbrowser returns error: 
"NotReadableError: The I/O read operation failed.".

Ofcourse the camera device is connected, and it's not used by the another process.

The strange thing is that this error is invoked randomly - it means that one day we cannot reproduce error, and on the other day we can't get video stream through whole day. Important information - this error is invoked only if we try to het video stream from Angular app, if we try to get stream without Angular method works perfectly.

We tried to use runOutsideAngular method from zone.js, but without any success.

Does anybody had this kind of problem? Could you help us with that?
