Screen sharing with Wayland

How is the status of screen sharing on Wayland? Recently this has become an essential topic for people who telecommute.

I am trying to share my screen on Google Chrome 88 with WebRTC and I run GNOME 3.36 with Wayland with the following packages:

• pipewire 0.3.11
• xdg-desktop-portal 1.8.0
• xdg-desktop-portal-gtk 1.8.0

I tried to setup everything from scratch with the following steps:

1. Build the packages with autotools and install the required dependencies along with their .pc files for pkg-config
2. Copy the .so shared libraries for pipewire to /usr/local/lib/x86_64-linux-gnu and run ldconfig to refresh the config
3. Copy the unit files in /usr/local/lib/systemd/user for systemctl and start the services

With everything correctly installed, I enabled chrome://flags/#enable-webrtc-pipewire-capturer and tried this demo and it says "Success!" but I only see a black screen...

If someone could help me with that, I would be grateful forever!

The easy solution is to use ubuntu 21.04 or later which properly integrates pipewire. Ubuntu 21.04 also defaults to wayland (intel and amd only) so pipewire screen sharing should work out of the box.

The reason is this ubuntu bug which seems to have been solved for 21.04. This issue is not caused by firefox or chromium/chrome.

You may also have some success backporting packages from 21.04 into 20.04 LTS. Unfortunately in this case the only easy solution cannot be used in ubuntu LTS until 2022 (when 22.04 LTS gets wayland and pipewire by default).

I got this info from a reddit comment where the same question is asked.
