Package: pipewire Version: 1.4.2-1 Severity: normal Dear Maintainer,
for some weeks I am unable to use screen sharing in video conferences using MS Teams. This applies to Firefox, Chrome and the MS Teams PWA. Screen sharing used to work fine for several months before. I am not aware of any relevant changes to the system I could have made. In order to get some insights I started Google Chrome in a terminal to see some output. Below is the output that is produced when I start Chrome, visit teams.microsoft.com, start a test call, and try to do screen sharing. > [0514/154506.166900:WARNING:chrome/app/chrome_main_linux.cc:80] Read channel > stable from /opt/google/chrome/CHROME_VERSION_EXTRA > Created TensorFlow Lite XNNPACK delegate for CPU. > [359294:359307:0514/154527.366983:ERROR:services/network/p2p/socket_tcp.cc:331] > Error when reading from TCP socket: -101 > [359224:359319:0514/154537.991896:ERROR:content/browser/browser_main_loop.cc:278] > GLib: g_main_context_pop_thread_default: assertion 'stack != NULL' failed > [359224:359317:0514/154537.991896:ERROR:content/browser/browser_main_loop.cc:278] > GLib: g_main_context_pop_thread_default: assertion 'stack != NULL' failed > [359224:359318:0514/154537.991906:ERROR:content/browser/browser_main_loop.cc:278] > GLib: g_main_context_pop_thread_default: assertion 'stack != NULL' failed > 'loop->recurse > 0' failed at ../src/pipewire/thread-loop.c:425 > pw_thread_loop_wait() In the application the error message I see is that "Chrome is unable to access camera." I tried to do screen sharing with Firefox and Jitsi which seemed to work. I also tried to start an KDE-X11 session, which did not help. The problem exists regardless of whether I use the laptops monitor or an external one. My system has set the environment variables WAYLAND_DISPLAY to wayland-0 and XDG_CURRENT_DESKTOP to KDE. The packages xdg-desktop-portal, -gtk and -kde are installed. I am reporting the bug to pipewire due to the error message above. If another package is more suitable, I would appreciate if you could let me know, so I could report the bug there. -- System Information: Debian Release: trixie/sid APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 6.14.5-bindeb-pkg-oldconfig+ (SMP w/4 CPU threads; PREEMPT) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=de Shell: /bin/sh linked to /usr/bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages pipewire depends on: ii adduser 3.150 ii init-system-helpers 1.68 ii libpipewire-0.3-modules 1.4.2-1 ii pipewire-bin 1.4.2-1 pipewire recommends no packages. pipewire suggests no packages. -- no debconf information
