Issue with wayland and OBS screen capture

charper_flow · 2023-12-18 18:11:49

I know this is a well documented issue but I have tried all of the solutions I have seen posted thusfar. I am trying to create a screen capture using OBS, however, I do not see screen capture as a potential source. I believe this is an issue with my pipewire. This is the debug file produced on launching obs:

I think my issues is highlighted in these two lines:

error: Source ID 'pipewire-desktop-capture-source' not found
error: Failed to create source 'Screen Capture (PipeWire)'!

I have the whole pipewire suite installed, and I have wireplumber and xdg-desktop-portal installed. I believe I am exporting my desktop variables correctly. This is what my .bash_profile file currently looks like:

# ~/.bash_profile
#

[[ -f ~/.bashrc ]] && . ~/.bashrc

if [ "$(tty)" = "/dev/tty1" ] ; then
        #Your environment variables
        export QT_QPA_PLATFORM=wayland
        export MOZ_ENABLE_WAYLAND=1
        export MOZ_WEBRENDER=1
        export XDG_BACKEND=wayland
        export XDG_SESSION_TYPE=wayland
        export SDL_VIDEODRIVER=wayland
        export XDG_CURRENT_DESKTOP=sway
        export GDK_BACKEND=wayland
        exec sway
fi

So I am quite at a loss of what to do next...Any and all help would be appreciated. I am happy to provide any more information

Is pipewire/wireplumber/xdg-desktop-portal-wlr installed and started?

systemctl --user status pipewire{,-media-session} wireplumber xdg-desktop-portal-wlr

charper_flow · 2023-12-19 00:46:33

I believe those are all installed. I don't have pipe-wire-media-session installed because it conflicts with wireplumber. When I run your request, I get the following results:

[charper@vinho ~]$ systemctl --user status pipewire{,-media-session} wireplumber xdg-desktop-portal-wlr

○ xdg-desktop-portal-wlr.service - Portal service (wlroots implementation)
     Loaded: loaded (/usr/lib/systemd/user/xdg-desktop-portal-wlr.service; static)
     Active: inactive (dead)

My guess is that I should do something like

systemctl --user enable xdg-desktop-portla-wlr.service

Would that be a reasonable next thing to try? It looks like pipwire is successfully started, but I'm not sure about those errors...

UPDATE

So I found a solution but I need a little bit of help to make it permanent:

dbus-update-activation-environment --systemd WAYLAND_DISPLAY XDG_CURRENT_DESKTOP=sway

systemctl --user stop pipewire wireplumber xdg-desktop-portal xdg-desktop-portal-wlr
systemctl --user start wireplumber

and then when I reload sway it all works! So, I need to execute these from from sway .config, which I know I can do with the

exec $file_name

command. But Im not exactly sure what file this should be...dose the extension matter? Is could I just call it activate_desktop_environ.sh?

Did you see the note in https://wiki.archlinux.org/title/Sway#Configuration? All of this should already happen granted you source the baseline properly.
