navigator.mediaDevices is undefined

Question

So I've made a WebRTC screen sharing app as a self-hosted alternative to Chrome Remote Desktop and other common remote desktop / game streaming services.

My dilemma isn't navigator.mediaDevices undefinded. Whenever I launch the app over a file:/// scheme it works perfectly; the same with https:// as mentioned within Mozilla's docs. But the problem is I don't want to host it as it has a few major security issue(s). So how would I host it on 192.168.XXX.XXXX without it giving the error? (I would like to host it on my local network so I can test it on other mobile devices.)

Solution 1

APIs with functions like getUserMedia, getDisplayMedia and enumerateDevices require a secure context, access to these from http: origins has been removed in Chrome back in 2019

For development, the easiest solution may be to create a self-signed certificate.

--UPDATE--

For development the easiest solution is to run from localhost, as that's considered secure - see https://blog.mozilla.org/webrtc/camera-microphone-require-https-in-firefox-68/ and https://w3c.github.io/webappsec-secure-contexts/#localhost

Solution 2

in mozilla developer go to about:config set to true media.devices.insecure.enabled and media.getusermedia.insecure.enabled

Actually, for development the easiest solution it to run from localhost, as that's considered secure - see blog.mozilla.org/webrtc/… and w3c.github.io/webappsec-secure-contexts/#localhost

The answer I've accepted is technically correct, but this one is very useful for rapid prototyping. I would recommend this if you are unable to host on localhost like the above answer.

MilkyDeveloper - you can't use your localhost server on other devices

I was losing my mind for a while trying about:config in Chrome and Brave, but that page only seems to exist in Firefox.
