In the openvidu-call app there is a screen where you can select input devices before connecting  
[https://openvidu.io/docs/demos/openvidu-call/](https://openvidu.io/docs/demos/openvidu-call/)

How is this done?  
Can it be done on the insecure-js.

I can’t seem to see any information on it.

Hello @Benjamin_Harris

You can get the video and audio devices with [getDevices()](https://openvidu.io/api/openvidu-browser/classes/openvidu.html#getdevices) method that openvidu-browser provide us.

And of course, you can add this feature into insecure-js app with using the [WebRTC API](https://developer.mozilla.org/es/docs/Web/API/MediaDevices) :

`navigator.mediaDevices.enumerateDevices()`
