Recording doesn't start with gnome-shell 41

[adangel]

Now that debian testing is also updated to gnome-shell 41, screencast seems to be broken in general.

E.g. ctrl+alt+shift+R doesn't start the gnome-shell built-in Screencast. Since EasyScreenCast uses the same dbus service, it also doesn't work.

Expected Behavior

Click on "Start recording" should start the recording. The timer should start counting. No errors should be reported.

Current Behavior

The timer does not start. There is a recording indicator visible (probably from gnome). After a few seconds, an error notification is displayed.

Logs

• Use journalctl /usr/bin/gnome-shell -f to monitor Gnome shell activity. Maybe the crash will log something.

There is no clear error message. The error "this.notifications is undefined" is probably something different and unrelated (but still also a bug).

Your Environment

• Gnome shell version: 41.0

• Operating System and version: Debian Testing

• Display server: Wayland

It seems, that wireplumber is required now. It replaces pipewire-media-session. As described in https://github.com/emersion/xdg-desktop-portal-wlr/wiki/%22It-doesn't-work%22-Troubleshooting-Checklist

If the service does not exist, your distro may package it as a separate package named something like pipewire-media-session. Screencasts will be stuck in the "paused" state without a session manager.

And pipewire-media-session has been replaced with Debian Testing now - https://metadata.ftp-master.debian.org/changelogs//main/p/pipewire/pipewire_0.3.39-1_changelog

• Don't build the pipewire-media-session binary package anymore,
  media-session has moved to a separate module to accelerate its
  deprecation in favour of WirePlumber.

Maybe it's not installed automatically yet and you need apt install wireplumber.
