KDE Wayland Doesn't Provide Way To Pick Video Source

[Hatsune-Cthulhu]

When trying to start a stream on KDE Wayland there's no option choose a video source, and clicking start stream just seams to do nothing other than spam the following line into the console:

[userscript] Did not find 'discord-screenaudio-virtmic', trying again in 100ms

Seen other users state that it's caused by there being no default input, this is not the case for me as I always have a microphone plugged in and the application works fine under X11.

I also get this on app startup:

Any help would be appreciated because I don't want to switch back to X11 due to frame pacing issues when gaming

Streaming on kwin/wayland is definitely possible. To my knowledge it requires the following components:

1. PipeWire (So no PulseAudio or alsa setup)
2. pipewire-v4l2 (not 100% sure on that one, but installing pipewire-pulse, pipewire-alsa, pipewire-audio and pipewire-v4l2 is a good idea anyway for a normal setup)
3. WirePlumber (To my knowledge plasma still uses pipewire-media-session, but replacing it should be handled automatically by your package manager when you install wireplumber)
4. xdg-desktop-portal-kde (and of course xdg-desktop-portal, but that should be installed as dependency by your pm)
5. polkit and polkit-kde-agent

When all this is installed, it should work without any further configuration.

When this doesn't help, you need to provide more information about your system (a good idea anyway)
