Testing WebRTC. Devices and Operating systems that support WebRTC or not.

Internet Explorer and the legacy version of Edge do not work!

Overview

Windows 10: Chrome, Firefox or the new Edge based in Chromium work
Mac: Safari, Chrome and Firefox work
iPad only works with Safari
iPhone works with Safari

I have positively tested WebRTC in these Platforms and browsers

The latest version of Edge (Based on Chromium)
Opera (current versions)
Avast Secure Browser
Brave
QQ Browser
Vivaldi
Yandex Browser

Mac:

Avast Secure Browser
Brave
Vivaldi
Yandex Browser

iPad:

Amazon Fire HD 10 Tablet:

Raspberry Pi 4 B:

Operating system Ubuntu 20.10 Desktop: Chromium 86 64-bit and above, Firefox 81 64-bit and above

Banana Pi Zero M2 A7 CPU H2+:

Operating system Ubuntu Desktop: Using Atollo USB Hub for Webcamera and Microphone. Massive lag however technically works

Linux & Unix-like:

CentOS
Debian
Mint
openSUSE
Ubuntu

Google Chromecast Sabrina:

You need a Webcam, Microphone and maybe Speakers in case your TV does not have those devices.
I used as USB Hub an Anker (8-in-1 USB-C Hub, PowerExpand USB-C Adapter, 100W Power Delivery), Amazon and
a more powerful power charger than the one supplied by Google, a RAVPower USB C, Charger PD, 90W, Amazon
Google Duo also works under this setup

Facebook Oculus Quest 2:

Using the ImmersedVR virtual Webcam on a Mac and the ImmersedVR app on the Oculus
Zoom also works with the Oculus using ImmersedVR virtual camera

WebRTC NOT supported or with issues

All Platforms:
- Internet Explorer, legacy Edge (Beware; both are standards in many corporations)
- (Issue) Firefox is very well supported and after Chrome recommended HOWEVER it has a known feature whereby speakers cannot be selected. We must wait for the Firefox developers to support this so we can use it in Bayron
- Tor Browser
Mac: The QQ Browser is not supported

Windows 8.1 and lower

Linux & Unix-like:
- FreeBSD 12.2 32-bit. After activating a camera via "$webcamd -d ugen<1.2> -i 0 -v 0 -B", using KDE Plasma 5.19.5.20.08.3, all 3 tested browsers Konqueror 20.08.3, Firefox 83.0 32-bit, and Chromium 84.0.4147.135 32-bit recognize a camera as tested in WebRTC samples, but only a black screen is shown
- OmniOS
- OpenIndiana

Xbox One or lower

Playstation 4 or lower

Raspberry Pi 4 B:
- RISC OS: 5.28 and below. No support for camera or mic at the OS level. Also, the only available browser, NetSurf 3.10, has limited JavaScript support, which is disabled by default btw

Your browser will ask you for permission to access your camera and microphone. Maybe your firewall also will ask. Some browsers may also present a checkbox asking if it should remember that decision. You better click on it
