Pipewire fails to initialize in Wayland #138

Closed roblem closed 3 years ago

roblem commented 3 years ago

Fedora 34 Workstation with pipewire, xdg-desktop-portal-gtk, and xdg-desktop-portal installed. I have two machines like this both running Wayland sessions. On one, pipewire support initializes and I have pipewire screencapture sources in obs. On the other, it persists with X11 (so only X11 screen capture sources are available) even when running under wayland session. From the terminal I ran flatpak run com.obsproject.Studio on both and captured stdout and stderr and here is the diff:

The one that works with pipewire is an upgraded machine that was running older obs versions with wayland support, so I suspect I am missing a dependency.

The one that doesn't work is running on top of X11:

-info: Window System: X11.0, Vendor: The X.Org Foundation, Version: 1.21.1

The PipeWire capture only works on Wayland, or on X11 with the OBS_USE_EGL=1 environment variable

roblem commented 3 years ago

Yes, that message confused me as I am running a wayland session and launching obs when the x11 window system message appears:

info: Distribution: "KDE Flatpak runtime" "5.15"
info: Session Type: wayland
info: Window System: X11.0, Vendor: The X.Org Foundation, Version: 1.21.1

Do I have to invoke the flatpak a certain way in wayland to use wayland rather than x11?

Also, for sure I am using wayland not x11 in gnome: wayland

roblem commented 3 years ago

If I launch with QT_QPA_PLATFORM=wayland flatpak run com.obsproject.Studio, I see the pipewire sources and I have

info: Platform: Wayland
info: Session Type: wayland

This env variable is unset on the machine that works.

GeorgesStavracas commented 3 years ago

This is really odd. Qt 5.15 indeed doesn't use the Wayland backend when you're running GNOME, but the KDE platform in Flathub removes this behavior. I'm not sure what's going on; perhaps there's any Qt env var to debug which backend is it picking, and why?

roblem commented 3 years ago

Not sure, but it is possible that some/all of the kde platform files were installed in an x11 session as I switched over to x11 early on in setting this computer up and forgot to switch back. Since both now work under Wayland I'll keep things as is in case anyone has ideas about how to debug the backend.

roblem commented 3 years ago

OK, the issue was the "bad" machine was setting

export QT_QPA_PLATFORM='xcb'

I removed that and it works as expected.
