stop the webcam streaming of getUserMedia without page refreshing [duplicate]

Answer 1

To get rid of the red symbol at browser's tab and for disabling both, the video and audio streams upon receiving one of these errors

Uncaught TypeError: localStream.stop is not a function
Uncaught TypeError: _webRTCStream.stop is not a function // TokBox, OpenTok

iterate over found tracks and stop them all.

if (_webRTCStream.stop) {
  _webRTCStream.stop() // idk what this does, left here for legacy reasons..?
} else {
  _webRTCStream.getTracks().forEach(function(track) { track.stop() })
}

note: _webRTCStream equals localStream, depends on a library you are using.
