I used to have screensharing working until it broke after running apt upgrade a month ago or so.

Sharing a window on Chromium currently does not work, it fails with:

pipewire[1613]: pw.context: params Spa:Enum:ParamId:EnumFormat: 0:0 Invalid argument (input format (no more input forma>

I tried upgrading wireplumber, pipewire and xdg-desktop-portal-wlr to more recent versions directly from source but no luck. Finally I found:

https://gitlab.gnome.org/-/snippets/39

Which, after installing gstreamer:

  1. Works itself
  2. While it is running, screeensharing on Chromium also works. If you close the script abruptly, the screensharing keeps working (as I am assuming, the pipewire sources are not destroyed). If you however, close the script gracefully, the screencast freezes (I am assuming the script is closing the sources), and I get:

Workaround

Use the script https://gitlab.gnome.org/-/snippets/39 before sharing the screen on Chromium, then terminate the script abruptly.
