html5 - How to turn off the local camera when using the getUserMedia method?

Question

I used the navigator.mediaDevices.getUserMedia() method to open the local camera. I need to close it after taking the photo, but how to close it? Help...

Answer 1

stream.getTracks()[0].stop();

stream is the instance in getUserMedia onSuccess callback

Please refer to the documentation

Answer 2

navigator.mediaDevices.getUserMedia(constraints).then(function(stream) {
      var track = stream.getTracks()[0];  // if only one media track
        // ...
       track.stop();
}).catch(function(err) {
  /* handle the error */
});
