Hello everybody,

i have two versions of chrome on my laptop

Version 84.0.4147.105 (Build officiel) (64 bits) => WORKING
Version 86.0.4221.3 (Build officiel) dev (64 bits) => NOT WORKING

Complementing:

a similar problem happened to me

when executing the code on a mobile device

if (navigator.mediaDevices.getUserMedia) {
            console.log('getUserMedia supported.');
            const constraints = {audio: true};
            let chunks = [];

            let onSuccess = function (stream) {

                if (!navigator.mediaDevices || !navigator.mediaDevices.enumerateDevices) {
                    console.log("enumerateDevices() not supported.");
                    return false;
                }

                //List microphones.
                navigator.mediaDevices.enumerateDevices().then(function (devices) {
                    devices.forEach(function (device) {

                        if (device.kind === "audioinput") {
                            console.log(device.label);//Other parameters device.kind/device.deviceId
                        }

                    });
                }).catch(function (err) {
                    console.log(err.name + ": " + err.message);
                });

            }

            let onError = function (err) {
                console.log('The following error occured: ' + err);
            }

            navigator.mediaDevices.getUserMedia(constraints).then(onSuccess, onError);

        } else {
            console.log('getUserMedia not supported on your browser!');
        }

the following error appears

• The following error occured: NotReadableError: Could not start audio source

Device : asus_z00lda , android 8.1.0

@larbijirari @alexandremsouza1 If console log navigator.mediaDevices.enumerateDevices() does it return anything at all?

Hi, i get the same error, but i not sure it due to the same problem. Previously I added the "resolution" parameter on component:

<vue-web-cam
          ref="webcam"
          :device-id="deviceId"
          width="100%"
          height="100%"
          :resolution = {width: 720, height: 720}
          @error="onError"
          @cameras="onCameras"
          @camera-change="onCameraChange"
        />

but this causes problems on some mobile phone. After remove "resolution" parameter than application goes normally
