1 year ago @columbarius Chromium on Arch fails like @WhyNotHugo described for me, and the version from flatpak fails the same:

Chromium 113.0.5672.126 In fact it's actually slightly worse - the flatpak version shows the same pw_thread_loop_wait and then seems to crash.

1 year ago i have the same error when trying to share my screen with chromium:

1 year ago I encountered the same issue. For me it works when I uninstall xdg-desktop-portal-gnome
I think the next release of xdg-desktop-portal will fix this.
https://gitlab.gnome.org/GNOME/xdg-desktop-portal-gnome/-/issues/74 https://github.com/flatpak/xdg-desktop-portal/pull/985 https://github.com/flatpak/xdg-desktop-portal/pull/1018
for the time being I have just following packages installed
❯ yay -Q | grep xdg-desktop-portal
xdg-desktop-portal 1.16.0-2
xdg-desktop-portal-gtk 1.14.1-1
xdg-desktop-portal-wlr 0.7.0-1I only have xdg-desktop-portal, xdg-desktop-portal-gtk, and xdg-desktop-portal-wlr installed, so @romanstingler's workaround isn't fixing it for me, FYI.

1 year ago afaict this is caused by the now-infamous webrtc bug (https://bugs.chromium.org/p/webrtc/issues/detail?id=15174), because applying the webrtc fix in question to firefox fixes it for me (will test chromium after it builds)
mvdan
commented
1 year ago What is the easiest way to apply the fix? Or, do we know if any firefox or chromium pre-release include the fix? It doesn't look like chromium has decided whether or not to include the fix in the upcoming v114, for example.
romanstingler
commented
1 year ago that is interesting. I am on Arch (testing) and use firefox-nightly 115.0a1+20230509.1+hfaf51404785d-1 and it works for me also with chromium 113.0.5672.126-1

1 year ago What is the easiest way to apply the fix?
you would have to apply the patch to the webrtc in the tarball of chromium or firefox and build it yourself (or get your distro to do it), and yes, that won't fix flatpak and similar..
an example for firefox and chromium
a noted hacky other workaround is PIPEWIRE_DEBUG=4 (yes, really), but that didn't fix it for me
It doesn't look like chromium has decided whether or not to include the fix in the upcoming v114, for example.
yes, seemingly that will be all the way in 115.. for firefox, it's in 114b, so also will be in 114 https://bugzilla.mozilla.org/show_bug.cgi?id=1832770
that said, it's not guaranteed this would fix it, you might also have other issues

1 year ago Thank you @nekopsykose, that's very helpful. I can confirm that Firefox 114.0b8 can screenshare for me, when 113.0.2 could not :)

1 year ago just updated chromium to 113.0.5672.126-r2, works :) (alpine edge)
mvdan
commented
1 year ago Chromium 114 on Arch, which presumably hasn't been patched by the distro for this, still doesn't work. So I imagine upstream might include the webrtc fix in the 115 beta. For now, back to Firefox for video calls :)

1 year ago Oh is screen capture with 10-bit an xdg-desktop-portal-wlr issue or a pipewire issue? As the errors I get when I have render_bit_depth 10 in my sway config, are talking about pipewire.

11 months ago Hi. I have this problem on Debian testing. Black screen with frozen mouse cursor.
But It seems that Chromium, Chrome and Firefox do not even attempt to connect to portals or pipewire.
pw-dump does not list any of them when attempting screen sharng.
If laucnhed without DISPLAY, eliminating Xwayland, screen sharing becomes totally disabled (Chrom* show only Tab, Firefox refuses to share outright).
All browsers run wayland-native, ozone and webrtc flags in Crhom* are applied.
Other wayland apps, like screenshots and screen recorders are working.
I have a feeling that I'm missing something trivial.

9 months ago for me in chromium it works intermittently on my notebook with external monitor. Sharing a tab or an area works. Sharing a display doesn't works every time.
I tried sharing my external one, was black. Then I tried sharing my internal display that worked and then sharing the external worked. Sometimes I have to try more often.
but I have only these installed
xdg-desktop-portal 1.18.2-1.1
xdg-desktop-portal-hyprland 1.3.1-3.1
I'm running
xdg-desktop-portal. It only yields a bunch of unrelated output:Another terminal is running
usr/libexec/xdg-desktop-portal-wlr, which also provides no useful output:On chrome, when I try to screencast at https://mozilla.github.io/webrtc-landing/gum_test.html, if I pick "Entire Screen" it logs:
But the screencast area is just solid black with "FPS now: NaN , entire capture: NaN".
Firefox logs nothing, and shows nothing (e.g.: not even a black region).
