native libwebrtc desktop capture on Wayland

[V I]

Hello,

Did anyone manage to get screen capturing working in a native app on Linux/Wayland? I'm currently on Ubuntu 22.04 / 106 branch and the only way for me to make it work is to select Ubuntu on Xorg on the log-in screen. I've tried all the 9x and 10x release branches, all the gn PipeWire flags and defines - nothing helps, it either fails silently without delivering a single screenshot or spits out black if built or configured not to use PipeWire (i.e. falls back to X11).

At the same time it works in Chrome - it used to be broken for a long time, but not anymore. I just can't figure out what the difference is as I build libwebrtc with the same flags and all.

TIA
