OBS Studio Black Screen at recording games with obs-vkcapture

@Naarmu

I wonder should I just install Wayland Session at this point.

Thank you for your time, I really like manjaro and just arch generally but it seems OBS got the better of me.

You could install Wayland. You could also try reverting to the 6.1 LTS kernel, or maybe try the newly released 6.6 kernel. I can’t say whether these options will improve the situation, but they might.

I have [the repo version of] OBS installed (KDE, Wayland, amdgpu, 6.6 kernel) with no apparent issues. The obvious common denominator between your issue and those on the thread previously linked, is the use of Nvidia graphics. Some highlights:

@maycne.sonahoz

I, for one, don’t have such issue.
Comparing my output with yours, i note that you all seem to use a Nvidia GPU, while i have an AMD one. Would it be Nvidia related?

This user has a less than desirable solution, but it worked:

@9op93odlo3

I had the same OBS issue … [Their] fix is to remove the nvida drivers and use the basic linux video drivers … until there is a fix.

Remember, these issues were from back in January; the cause in your situation might be entirely different; although it seems to tick all the boxes.

[Naarmu]

I completely forgot the kernel change in my mind thanks for giving me some fresh new ideas.

But yeah I do believe its my RTX3070 is at fault here. My pc does have hard freezes when browsing with Firefox and Brave until I had to put in GRUB boot parameter pci=nommconf to stop that. I checked the logs and the error was PCIe Bus Error: severity=Corrected, type=Physical Layer, (Receiver ID).

The same freezes were also on Linux Mint Ubuntu.

But yeah I will jump to 6.6 kernel and if nothing I will jump to 6.1LTS, and if that won’t work then will try to use Wayland session.

@Naarmu

But yeah I will jump to 6.6 kernel and if nothing I will jump to 6.1LTS, and if that won’t work then will try to use Wayland session.

Another popular resolution (again, in the other thread) was to remove the libva-vdpau-driver completely. That might also be a valid option if there is an updated version forthcoming.

I mentioned reverting to the nvidia-linux driver earlier. This post (in the other thread) was also well received, with several claiming it solved their issue.

[Naarmu]

I did remove libva-vdpau-driver and nothing helped after that I installed libva-nvidia-driver also and still nothing.

I tried to change kernal to 6.6 and later to 6.1LTS and nothing helped. Just in case I also reinstalled nvidia driver to for each kernel.

About reverting to the nvidia-linux also did not helped my situation.

I tried to install plasma-wayland-session and I couldn’t even log in to Wayland session so back to x11.

Like the only thing I could think of is to do BIOS update.

[soundofthunder]

@Naarmu

I tried to install plasma-wayland-session and I couldn’t even log in to Wayland session so back to x11.

What was preventing you logging in?

Did you remember to select ‘Wayland’ (bottom left corner of SDDM)?

[Naarmu]

To be frankly honest I don’t know. When I installed Wayland, the system required a reboot. Once the system was booting it was stuck at Linux BIOS/bootting(sorry I can’t tell what it is) screen where is says bunch of OK OK OK for each line. In there the system couldn’t boot. I had to do a hard reset for the system and it booted normally as usually.

In the Login screen I selected Wayland session and all I see is a black screen for about 4 seconds and then returns back to the Login screen.

Disturbing, in itself.

You might have better luck installing it outside of the GUI. This tutorial explains how to perform an update in that way; it’s the same principle:

[Naarmu]

I also tried this to check regarding my ffmpeg with:

ffmpeg -y -vsync 0 -hwaccel cuda -hwaccel_output_format cuda \                                                                                    ✔ 
      -f lavfi -i testsrc -t 50 \

      -vf hwupload -c:a copy -c:v h264_nvenc -b:v 7M -f null -

And this is what I got:

I have no idea what this means but it seems I have an issue with ffmpeg

I will check about the updates as well thank you for the help

[soundofthunder]

@Naarmu

I have no idea what this means but it seems I have an issue with ffmpeg

Out of interest, what’s the resolution of whatever you’re trying to encode?

[Naarmu]

I am trying to record at 1920x1080 60fps.

So far I found about this https://github.com/keylase/nvidia-patch and trying to figure out if my NVIDIA has some sort of limitations placed in.

[soundofthunder]

@Naarmu

I am trying to record at 1920x1080 60fps.

I found this similar issue with nvenc on StackOverflow. A workaround suggested was to use libx264 instead of h.264. You could also try encoding at a lower resolution, for the sake of testing, to see if it completes without:

[h264_nvenc @ 0x5624e69380c0] OpenEncodeSessionEx failed: out of memory (10): (no details)
zsh: segmentation fault (core dumped)  ffmpeg -y -vsync 0 -hwaccel cuda -hwaccel_output_format cuda -f lavfi -i  -t

Also, can you post the output of:

inxi --admin --verbosity=7 --filter --no-host --width

Update:-

This appears to be a known issue: OBS studio crashes upon clicking Start Recording #9764. No indication of a fix, however.

“A workaround: setting software encoder instead of NVENC HEVC/H.264 (both cause crash).”

So, it’s not just you; that’s some consolation, at least.

[Naarmu]

Well how to say I don’t want to sound greedy or anything just I need best performance for recording heavier demanding games.

I can record Screen Capture with (Xcomposite) on OBS but with all kinds of settings the quality is just not good.

Screen Capture with (Pipewire) does not even see any windows to select just blank.

So I wanted to use obs-vkcapture since people say its easier for the system to record with minimal loses of quality especially when recording heavy performance demanding games.

So yeah anyway from the inxi --admin --verbosity=7 --filter --no-host --width:

And software encoder also does not seem to work with obs-vkcapture.

I tried to record with different resolutions and so on but same problem.

Just to let people know I tried setting launch parameters in the game as obs-gamecapture #command# and obs_vkcapture=1 #command#. And all get is black screen with sounds.

At face value, it seems there’s nothing we can now suggest, until the OBS Project have addressed the linked issue #9764, and a fix filters down to the lower levels. The best you can do is keep monitoring there for a possible workaround in the meantime. It’s not a Manjaro issue.

[Naarmu]

Sine I saw OBS as native on Linux that’s pretty much why I jumped from Windows since I just don’t like their’s crazy terms of service agreements policies.

I don’t know who is at fault here is it obs or nvidia or both.

Thanks anyway for all your time and help. I will still keep on trying to find out anything. If I do I will report back.

Just an Update

I checked my Proton logs when launching steam game via proton.

I see this issue

[obs-vkcapture] missing device extension: VK_EXT_external_memory_dma_buf

This vulkan extension was implemented in 515 version for the driver, mine is 535 so not sure what is the deal here.

@Naarmu

This vulkan extension was implemented in 515 version for the driver, mine is 535 so not sure what is the deal here.

On the obs-vkcapture GitHub page it states that the “Nvidia Driver version >= 515.43.04 and nvidia-drm.modeset=1 kernel parameter are required” for game capture. So, the theory is that any higher version will support it.

You are currently using Nvidia 535 drivers. If there is any issue with them, a new version is in the pipeline. Nvidia 545 drivers are currently in Testing (or, at least, they were yesterday) – See Nvidia 545 drivers might have issues – They typically won’t reach the Stable branch until any current issues are resolved. Hopefully, that won’t take too long.

However, I could find nothing that positively suggests Nvidia drivers are at fault; they may contribute to some extent, but nothing more. An internet search revealed many references to VK_EXT_external_memory_dma_buf but I found nothing that seemed significant.

As mentioned, the culprit appears to be the NVENC HEVC/H.264 crash referenced by OBS Project issue #9764 (and also present in your logs), which triggers a segmentation fault when attempting to record.

Leave this unsolved for a while if you like, but there’s no guarantee how long the OBS Project may take to reproduce the error, and push a fix. When that happens, it will no doubt filter down to all relevant packages. It’s probably best to start a new thread at that time.

Cheers.

Okay I GOT IT TO WORK.

Not sure if OpenGL programs will work with NVIDIA but this is good enough.

You reminded me of nvidia-drm.modeset=1 again. I have tried this before but my games did not launch at all that time.

But since I thought I am now on Kernel 6.1 LTS I put back nvidia-drm.modeset=1 in GRUB file, and it WORKS.

There is a possibility that there could be other factors that came to play to make things work, so for people you might have problems(these are probably just optional steps).

I uninstalled libva-vdpau-driver and installed libva-nvidia-driver instead.

in /etc/environment text file I put OBS_USE_EGL=1 obs setting. (This is for X11)

Okay I GOT IT TO WORK.

Great. That saves a lot of wild geese.

Cheers.

Thank you for all the help and guides. I was about to give up until you mentioned about changing the modest.

God bless you.
