No image in gUM, `xdp-screen-cast.py` #267

GladOSkar · 2023-04-20T15:43:26Z

My issue is very similar to #88 and #99 but i didn't want to necro those.

System:

OS: Void
Kernel: 6.1.21
x86_64-musl

Software:

xdg-desktop-portal 1.16.0
xdg-desktop-portal-wlr 0.6.0
pipewire + pipewire-media-session + gstreamer1-pipewire 0.3.68
sway 1.8.1
firefox 112.0
chromium 112.0.5615.49

gUM on FF:

on chromium it's a black square with NaN FPS and NaN resolution

Tried all of the Troubleshooting Checklist. Nothing helped. Some Info regarding the tips there:

Screen recording in OBS works fine
I'm not running pipewire as a runit service, but start it directly
I start sway with XDG_CURRENT_DESKTOP=sway dbus-run-session sway so dbus-update-activation-environment should not be needed, but i did try adding it to my sway config and it did not help.

$ echo $XDG_CURRENT_DESKTOP $WAYLAND_DISPLAY
sway wayland-1
$ < "/proc/$(pidof xdg-desktop-portal)/environ" tr '\0' '\n' | grep '^XDG_CURRENT_DESKTOP='
XDG_CURRENT_DESKTOP=sway

.config/xdg-desktop-portal-wlr/config:

[screencast]
output_name=eDP-1
max_fps=30
chooser_cmd=slurp -f %o -or
chooser_type=simple

The chooser does pop up and i can choose a display, as seen below, but then there is nothing to be seen.

^ This is the one thing i didn't find in any other issue, but it seems to just be a gstreamer thing?.

Thank you for any help, and thanks for your work in general! :)

I have the same issue on hyprland. What graphics card do you have? It also works in OBS for me but not in any other app (tried firefox, chromium, telegram desktop) although for me the the resolution and framerate seem fine, just output a black screen

GladOSkar · 2023-04-23T01:50:58Z

What graphics card do you have?

Just an internal Intel Alder Lake-P

spameier · 2023-04-25T04:46:34Z

@GladOSkar I have the same error on the latest version of Chromium and Firefox but not in Firefox ESR on Alpine Linux, which makes me think it's related to the Browser. Can you try with ESR aswell? Also related: #255.

GladOSkar · 2023-04-25T06:40:25Z

@spameier you're right, it works in Firefox ESR (102.9.0) for me as well

Update: I was using the mesa-git package which I had a lot of graphical bugs on. I have since switched to mesa-amdonly-gaming-git which seems to have resolved both my general graphical glitches in the mesa bug report but also my screenshare capabilities.

It's entirely possible that this was fixed in mesa HEAD and my switching of packages was a coincidence so I'll come back here and update once I've checked that.

GladOSkar · 2023-04-27T12:13:30Z

I use neither an AMD GPU nor do i have graphical glitches, so i doubt that'll help. But good to know!

ilya-zlobintsev · 2023-05-02T08:48:03Z

For me this issue does not seem to appear on the Flatpak version on Firefox, only on the Arch package version.

mailhost · 2023-05-05T10:16:03Z

Dropping pipewire to version 0.3.67 (from 0.3.69 and 0.3.70) resolved my issue; xdpw would report the same output as in this issue. Chrome/Chromium would report 'Failed to connect PipeWire context'. The Flatpak versions of things (Firefox/Chrome/Chromium) worked A-OK.

edit: xdp-screen-cast.py does not work, but after using firefox 114.0b9 and making sure my displays were 8-bit, now works.

GladOSkar · 2023-05-27T14:47:40Z

pipewire 0.3.71 does not work for me either.

GladOSkar · 2023-07-05T13:31:30Z

Tried it again today and suddenly it worked. Don't know what update was responsible, but here are my new versions:

xdg-desktop-portal 1.16.0
xdg-desktop-portal-wlr 0.7.0
pipewire + gstreamer1-pipewire 0.3.72
wireplumber 0.4.14
sway 1.8.1
firefox 114.0

I'll assume it was firefox, but who knows ¯\_(ツ)_/¯
