I have mic and camera but I was getting the same error. I was pretty sure that was related to laptop setting, because I tried everything. turns out my laptop was blocking access to the media. I am using linux and laptop brand name is MSI, I started to look for any sign that related to the camera setting. On F6 button, my laptop has a webcam icon. So I clicked on

fn + F6

It works now. most likely sometimes I click on fn+* keys to see any difference and I blocked the camera access.

This issue can also occur on some mobile devices (Sony XA2 running Android) if you had previously already created a MediaStream.

The solution that I found was to make sure to stop all the tracks of previous streams that you created.

 this.stream.getTracks().forEach(t => {
    t.stop();
    // I don't think removeTrack is necessary, but just keeping it.
    this.stream.removeTrack(t);
 });

Without the previous code you can't seem to toggle camera on certain Android devices: (Demo), (Code) The error shown was DOMException: Requested device not found

By stopping previous tracks: you are able to start a new stream: (Demo) Code

Use this line to initialize the webcam and microphone:

navigator.mediaDevices.getUserMedia({ audio: true, video: true });

In my case i have connected external camera through USB i was able to get the devices, i was getting kind of devices as audiooutput and videoinput, and there was no audioinput(microphone device) but while i was requesting for devices i passed constraints as..

function Webcam(){
  this.constraints = {
    video: true,
    audio: true
  }
  this.userMedia = null;
  this.mediaDevices = navigator.mediaDevices;
  this.initialize = function(){
    this.userMedia = this.mediaDevices.getUserMedia(this.constraints);
  }
}

let webcam = new Webcam();
    webcam.initialize();

So Promise not satisified and getting error as Requested device not found.

This happens when you dont have any device to capture video or capture audio

try checking if your webcam and your microphone are working fine

try changing this line:

_video.src = window.URL.createObjectURL(stream);

with this one:

_video.srcObject = stream;
