Hi there, I have been experimenting with the UI experimental browser feature and seeing what kinds of features the browser supports. In the online documentation, I can’t see which browser this UI Widget feature is based on. Is it a particular build of the Chromium Embedded Framework (CEF)? If so, is there a way to find this in the source code so we can extend it (or update it)? In particular, what I would like to know is will the browser support WebRTC? I have tried using the experimental browser to log into several WebRTC applications, but none of them seem to connect and display shared video or audio from the person on the other side. The site will load, but audio and video shared by other participants in the call will not. I tried using these two demo WebRTC apps: [https://apprtc.appspot.com/](https://apprtc.appspot.com/) and [https://rabb.it/](https://rabb.it/) I also can’t seem to find a way to give permission to the website to have access to my PC’s webcam or microphone. Ideally, this would be a nice feature for folks who want to take advantage of WebRTC’s low latency video and audio sharing. As a side note: When looking at the release notes for Version 4.12, one of the fixes mentions WebRTC on the PS4. This is the only mention of WebRTC I could find anywhere. > **[Unreal Engine 4.12 Released!](https://www.unrealengine.com/en-US/blog/unreal-engine-4-12-released)** > > Unreal Engine 4.12 has been released and it is packed with loads of new content, including 106 updates from the talented developer community via GitHub! In this release, you'll find Sequencer, our new, non-linear cinematic tool, Daydream VR support,... And before anyone asks, yes I did look into Coherent GT and BLUI, but neither of these are the built-in experimental browser. That is the browser I am asking about. ---

UE4 use raw CEF ([Chromium Embedded Framework - Wikipedia](https://en.wikipedia.org/wiki/Chromium_Embedded_Framework)) which is web browser engine taken off Chromium (Chrome practicly, also note that web browser engine is thing that displays website in the browser) and it seems it does not support WebRTC out of the box, it something that browser using CEF need to implement. I find this, it mentions some 3rd party patch to WebRTC in CEF, if you skilled enouth you might try to experiment with this: > **[Log in with Atlassian account](https://id.atlassian.com/login?application=bitbucket&continue=https%3A%2F%2Fbitbucket.org%2Faccount%2Fsignin%2F%3Fnext%3D%252Fchromiumembedded%252Fcef%252Fissues%252F1065%26redirectCount%3D1)** > > Log in to Jira, Confluence, and all other Atlassian Cloud products here.

Thanks for the reply! Do you know where the location of the CEF files are in the UE4 engine directory? If I wanted to modify and patch the CEF files to support WebRTC, where do I need to look in my local directory? ---

You could also look into Unreal’s [XMPP](https://xmpp.org/uses/webrtc.html) integration: [here](https://docs.unrealengine.com/latest/INT/API/Runtime/XMPP/index.html). ---
