Oculus screen casting in custom web application

I'm trying to create a web application (for PC) that will display the screencasting from Oculus Quest. I don't want to create any native application for oculus to catch the stream, so I tried 2 approaches:

  1. Create a webpage for Oculus with screencasting option and then using webrtc stream it to the browser on PC - but this doesn't work I cannot get the screen stream - Oculus browser (based on Android Browser) doesn't support Screen Capture API - 
  2. Use Oculus Casting (this which works with oculus.com/casting or mobile Oculus application). Still, I cannot find any API documentation for that. I've tried to check how the oculus page works - it uses the webrtc under the hood, but when I tried to use the webrtc offer taken from graph.oculus.com/graphql - I get the following error:
ERROR Error: Uncaught (in promise): InvalidAccessError: Failed to execute 'setRemoteDescription' on 'RTCPeerConnection': Failed to set remote offer sdp: Called with SDP without DTLS fingerprint.
Error: Failed to execute 'setRemoteDescription' on 'RTCPeerConnection': Failed to set remote offer sdp: Called with SDP without DTLS fingerprint.

that means that the sdp from Oculus API doesn't contain the fingerprint. I tried to find a way to disable this chrome security check using the --disable-webrtc-encryption, but it doesn't work..

Have you any other suggestions or hints?

    I'd be interested in how you go with this.
    I want to have an app on a tablet that allows me to change settings on an app on the headset but be able to see what is in the headset.
    Both Unity apps

    Hi sseget.

    I'm doing work at the university I need to create a website that will display the screencasting of the Oculus Quest 2 in real time. Where can I start studying to be able to do it?

    This is an old thread for sure but in case anyone comes looking...I'm building such an app using Unity URS package.

    I'm sending my own camera feed from my unity app to my web app over webrtc. 

    I'd like to be able to stream the headset stream when my unity app has lost focus although I don't know this is possible.
