Subject: [bug#52492] [PATCH 0/7] Improve screen sharing support under Wayland
Date: Tue, 14 Dec 2021 22:45:02 +0100

Hello,

This patchset updates and improves various packages related to screen
sharing/screeshotting on Wayland, and especially wlroots-based
compositors.

I can get screensharing working in icecat on sway by manually starting
pipewire then wireplumber (and then xdg-desktop-portal-wlr followed by
xdg-desktop-portal if they're not installed in your profile, otherwise
your user DBus session will launch them automatically), and starting
icecat with

`LD_LIBRARY_PATH="$(./pre-inst-env guix build
pipewire)/lib:$LD_LIBRARY_PATH" icecat`

since the pipewire library is dlopened by libwebrtc rather than
statically or dynamically linked.  We could possibly add this to the
icecat package, as it has a wrapper doing a similar thing for other
libraries.

Another way to test screensharing without icecat would be to use this
python script [1], using `guix shell python python-pygobject
gst-plugins-bad pipewire python-dbus -- python3 xdp-screen-cast.py`.

I also took the liberty to patch xdg-desktop-portal-wlr's
screenshotting process, as it simply execl'd to slurp and grim.  Along
with an update to flameshot, I can use the latter properly on sway as
well.

Best,
Josselin
