Track not stopping

See original GitHub issue

Issue Description

Since 1.2.0 upgrade, it looks like stream tracks are not stopping, and the chrome red light is left on even after component unmount. Does anyone have the same issue ?

I tried to stop the stream tracks through a “VideoPreview” function component with no success !

const VideoPreview = ({ stream, status}) => {
  const videoRef = useRef()

  useEffect(() => {
    if (videoRef.current && stream) {
      videoRef.current.srcObject = stream;
    return () => {
      if (status == 'stopped') {
        stream.getTracks().forEach(track => track.stop())
        stream.getTracks().forEach(track => (track.enabled = false))
  }, [stream]);

  if (!stream)
    return null;

  return <video ref={videoRef} id="localVideo" className="video-preview" autoPlay muted/>;

Seems like there’s a missing opened stream left unstopped somewhere… Would that be a bug on our side ?

It is not fixed ❗

Use case: if the user “closes” the recorder before starting to record, then there is no way to stop audio tracks because mediaRecorder.current = null and previewVideo only contains video tracks (

Maybe consider providing a stopAudio render prop OR adding getters for mediaRecorder and mediaStream.
