OBS Linux Vulkan/OpenGL Game Capture

OBS plugin for Vulkan/OpenGL game capture on Linux.

Installation

AUR

64 bit: obs-vkcapture-git

32 Bit: lib32-obs-vkcapture-git

Flatpak

flatpak install com.obsproject.Studio.Plugin.OBSVkCapture

flatpak install org.freedesktop.Platform.VulkanLayer.OBSVkCapture

OBS plugin: com.obsproject.Studio.Plugin.OBSVkCapture

• This ONLY gives the plugin.
• You will need to install native obs-vkcapture if you want to capture native games.
• You will need to install Flatpak Capture Tools if you want to capture Flatpak games.

Capture Tools: org.freedesktop.Platform.VulkanLayer.OBSVkCapture

• This is needed for Flatpak games. It doesn't matter whether you are running Flatpak OBS or native OBS.

Manual

Dependencies

• cmake
• libobs
• libvulkan
• libgl
• libegl
• libX11 (optional)
• libxcb (optional)
• libwayland-client (optional)
• wayland-scanner (optional)

To install system-wide you need to use sudo make install

    mkdir build && cd build
    cmake -DCMAKE_INSTALL_PREFIX=/usr ..
    make && make install

Usage

1. Add Game Capture to your OBS scene.

2. Start the game with capture enabled:

   1. If Vulkan, use env OBS_VKCAPTURE=1 <APP>
   2. If OpenGL, use obs-gamecapture <APP>
   3. If obs-gamecapture doesn't work on Flatpak for OpenGL, try:

   flatpak run --env=LD_PRELOAD=/usr/lib/extensions/vulkan/OBSVkCapture/lib/x86_64-linux-gnu/libobs_glcapture.so <APP>

• Replace <APP> with the application you are trying to start.
• If using Steam launch options, replace <APP> with %command%

Troubleshooting

NVIDIA

Driver version >= 515.43.04 and nvidia-drm.modeset=1 kernel parameter are required. In Wayland session make sure OBS is running on Wayland and not XWayland.

OpenGL game crashing or not capturing video

A potential workaround for this is to use Zink for converting OpenGL to Vulkan and then using Vulkan capture instead. May cause issues or reduced framerates with certain games/programs.

env MESA_LOADER_DRIVER_OVERRIDE=zink OBS_VKCAPTURE=1 <APP>

No Game Capture source available in OBS 27

If you are on X11, make sure you run OBS with EGL enabled: OBS_USE_EGL=1 obs.
