Answer 1

我得到以下建议

Make sure that if you are switching cameras to stop any existing tracks. Stop all tracks in an active stream before acquiring a new one.

我尝试了以下并解决了

## OK
navigator.mediaDevices.getUserMedia(video: true,audio: true).then((mediaStream) =>
        mediaStream.getTracks().forEach((track) => track.stop())
)
## NG
localStream.getVideoTrack().stop()
localStream.getAudioTrack().stop()
