[SOLVED][Wayland] Crash On Pipewire Screen Capture obs-studio 31.0.0-1

Nyctfall · 2024-12-13 18:24:51

Hello Arch Linux community, thank you for your consideration and time! I tried to fix this myself, but I'm low on troubleshooting time.

The closest similar issues that were found: (GitHub obsproject/obs-studio "Crash when initializing PipeWire screen sharing since 31.0.0 (GNOME Wayland) #11617", GitHub obsproject/obs-studio "libobs/util: Crash on bmalloc(0) #11181"), which seems to confirm my suspicions that the crash's characteristics indicate this is intentionally done by the OBS Project's devs. After troubleshooting this since doing a pacman upgrade on 2024-12-09, it appears that others are getting the same crash as well. According to GitHub obsproject/obs-studio "Memory allocator cleanups #6721", OBS dev "notr1ch" said it shouldn't be a bug in OBS directly, but in a 3rd party plugin. However, I do not have any external 3rd party OBS plugins, just the dependencies and optional dependencies for the package (See foonotes * and **).

Question:

Should I make an Arch Linux GitLab bug report for "obs-studio 31.0.0-1" having intentional bugs by the upstream OBS devs?

Problem:

When trying to use OBS for screen capture with Wayland, the 'Screen Capture (PipeWire)' mode will cause the app to crash under Wayland or XWayland when a screen/app capture source is selected. Under an X.Org KDE desktop session, the "Open Selector" button for "Screen Capture (PipeWire)" will not open a "Screen Sharing" KDE dialog menu window, making selecting a capture source non-functional (as well as any previously configured capture sources for PipeWire screen capture also being non-functional).
This was noticed after upgrading "obs-studio (30.2.1-2 -> 31.0.0-1)".

Steps to reproduce:

Arch Linux (Installed according to Arch Wiki),
Linux kernel (linux 6.12.4.arch1-1),
Desktop Manager (gdm 47.0-2) and Wayland (wayland 1.23.1-1), with KDE Plasma 6 (plasma-desktop 6.2.4-1, plasma-meta 6.1-1) or GNOME 47 (gnome-desktop 1:44.1-1, gnome-session 47.0.1-1, gnome-shell 1:47.2-1)
Pipewire (libpipewire 1:1.2.7-1, pipewire 1:1.2.7-1) with WirePlummer (libwireplumber 0.5.7-1, wireplumber 0.5.7-1)
OBS Studio (obs-studio 31.0.0-1, ffmpeg 2:7.1-3, alsa-lib 1.2.13-1, glibc 2.40+r16+gaa533d58ff-2, gcc-libs 14.2.1+r134+gab884fffe3fc-1, systemd-libs 257-1, pam 1.7.0-1, pipewire-audio 1:1.2.7-1, mesa 1:24.3.1-3)
Start a Wayland desktop session,
Open OBS (through .desktop file, terminal, or with GDB)
Click the "+" ("Add Source") button in the "Sources" section, and select "Screen Capture (PipeWire)" option,
In the "Properties for 'Screen Capture (PipeWire)'" OBS pop-up window, click the "Open Selector" button. (This step will fail under an X.Org desktop session.)
In the "Screen Sharing" GNOME/KDE pop-up dialog menu window, select any of the options under either the "screens" tab or the "windows" tab (for attached/virtual monitors or open application windows respectively),
Immediate crash (SIGTRAP under GNU Debugger)
Get a SystemD coredump file added to /var/lib/systemd/coredump
...
Profit?

Details:

Starting OBS with "--verbose" (GDM, KDE, Wayland), and without selecting a capture source that will crash OBS, outputs: http://0x0.st/XFqo.txt (X.Org X11: http://0x0.st/XFBw.txt, doesn't crash, but instead will error "warning: [pipewire] Failed to create session, denied or cancelled by user")

This seems to indicate some sort of permissions issue with Pipewire or WirePlumber and Wayland portals, as a "Monitor Source" option is not available under the "+ (Add Sources)" menu.

Checking a core dump from one of the OBS crashes shows: http://0x0.st/XFmb.txt

$  coredumpctl -1 gdb
# ...

Which appears to indicate the call to 'bmalloc' is the cause of the crash.

GDB appears to confirm this when running 'obs --verbose': http://0x0.st/XFme.txt (XWayland: http://0x0.st/XFB4.txt)

See: https://wiki.archlinux.org/title/Downgr … cman_cache or https://aur.archlinux.org/packages/downgrade
I have to downgrade to a working version... haven't done so yet.

Worksforme™ obs, ffmpeg and KDE from the repos, are you using a custom ffmpeg version? Are the corresponding xdg-desktop-portal installed, do you maybe have a conflict in started xdg portals if you have gnome and KDE installed at the same time? What GPU?

Hi @V1del,
I'm honored to be in the presence of a legendary Archer, hope your day is going well!

According to GitHub user "AngryPenguinPL" on the GitHub obsproject/obs-studio "Crash when initializing PipeWire screen sharing since 31.0.0 (GNOME Wayland) #11617" thread, unfortunately this is an upstream issue.

It's confirmed to be fixed with the upstream patch: GitHub obsproject/obs-studio "libobs-opengl: Avoid trying to allocate 0 byte on Linux #11618", but GitHub obsproject/obs-studio "libobs-opengl: Fix for formats with zero modifiers #11638" looks like a more concise (untested) solution.

Since the only solution is a complete package rebuild and recompilation, I suppose that means this problem should either: 1) be on the GitLab Bug Tracker, or 2) be the reason why (foreshadowing) a potentially borked update in OBS Studio shouldn't be the go to decision made by upstream when they notice more rigorous testing methodologies are needed (see: GitHub obsproject/obs-studio "Memory allocator cleanups #6721" and GitHub obsproject/obs-studio "libobs/util: Crash on bmalloc(0) #11181").

Answer: Yes. And I am not experienced in identifying conflicts with GNOME and KDE Wayland Portals... but I do not believe that to be the case.

According to the official OBS Project's website OBS Studio download page: OBS Project download OBS Studio on 2024-12-06 (Date of pkg update to "obs-studio" "v31.0.0-1" by Arch Linux GitLab packager @svenstaro in official Arch repos), and OBS Project download OBS Studio on 2024-12-15 (closest snapshot to today's date).
Linux was NOT supposed to get the update to "obs-studio" v31.0.0 to all Linux users!

The official Arch Linux "extra" repo version of "obs-studio" should still be "v30.2.3-2", Arch Linux GitLab Packages/obs-studio "upgpkg: 30.2.3-2: Rebuild for Python 3.13", while the "extra-testing" repo version of "obs-studio" should now have "v31.0.0-1" (or "v31.0.0-2") Arch Linux GitLab Packages/obs-studio "upgpkg: 31.0.0-1".

My apologies, I was corrected by upstream OBS Project dev @tytan652:

We had an issue while publishing the Flatpak so the website reflects Flathub version, nothing more.

According to: GitHub obsproject/obs-studio "CI: Disable Flatpak bundling on publish #11592", GitHub Actions v3 has recently been deprecated just before the release of OBS v31.0.0. This seems to be why the FlatHub release is delayed. As referenced upstream (here), the GitHub obsproject/obs-studio "Publish Repository" GitHub Action was affected by GitHub @actions/upload-artifact > "v4 - What's new" > "Breaking Changes" > 2:

`actions/upload-artifact@v3` is scheduled for deprecation on November 30, 2024. Learn more. Similarly, `v1`/`v2` are scheduled for deprecation on June 30, 2024. Please update your workflow to use `v4` of the artifact actions. This deprecation will not impact any existing versions of GitHub Enterprise Server being used by customers.

Uploading to the same named Artifact multiple times. Due to how Artifacts are created in this new version, it is no longer possible to upload to the same named Artifact multiple times. You must either split the uploads into multiple Artifacts with different names, or only upload once. Otherwise you will encounter an error.

GitHub Blog "Deprecation notice: v3 of the artifact actions"

Starting January 30th, 2025, GitHub Actions customers will no longer be able to use `v3` of `actions/upload-artifact` or `actions/download-artifact`. Customers should update workflows to begin using `v4` of the artifact actions as soon as possible. While `v4` of the artifact actions improves upload and download speeds by up to 98% and includes several new features, there are key differences from previous versions that may require updates to your workflows.

Arch Linux GitLab packager @svenstaro just released a possible fix in the official Arch Linux "extra-testing/obs-studio" repo (upgpkg: 31.0.0-3: Try to fix #9)

I'm testing it now...

Having the same problem! Pleas tell me if you find a solution.

The [extra-testing]/obs-studio v31.0.0-4 fixes the bug in my testing, upgpkg: 31.0.0-4: Fix #8.
See: Arch Linux Wiki > Official Repositories > Testing Repositories for info on installing from repo, I personally used the PKGBUILD like an AUR script.

See logs:

Try to rebuild ALL of your packages, this worked for me, I was getting similar crashes for libc.so.6 on KDE Arch / EndeavourOS for various random applications.

@SlayerTheChikken
Hey man, welcome to the forums!

I would like to point out that this thread has already been solved and is entirely conclusive with the solutions upstreamed to fix the upstream bug in obs-studio 31.0.0-1 with [extra-testing]/obs-studio 31.0.0-3.

It seems like you meant to reply to the "Kernel" topic thread 2219162 "amd gpu problems".
