Changes

Added kmsgrab utility. To activate, compile and install plugin, then run:

sudo vkcapture-kmsgrab

In list of vkcapture sources you will find "vkcapture-kmsgrab", which is fullscreen capture, universal to X11, Wayland, and even virtual console.

OBS Linux Vulkan/OpenGL game capture

OBS plugin for Vulkan/OpenGL game capture on Linux.

AUR: obs-vkcapture-git

Flatpak:

• OBS plugin: com.obsproject.Studio.Plugin.OBSVkCapture
• Capture tools: org.freedesktop.Platform.VulkanLayer.OBSVkCapture

About Flatpak

If you use Flatpak OBS, you need to install Flatpak OBS plugin.
If you use Flatpak Steam, you need to install Flatpak Capture tools to be able to capture games running inside Flatpak Steam runtine.

For capturing games outside Flatpak runtime, you need native build regardless of if you are using Flatpak OBS or not.

Dependencies

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

Building

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 obs-gamecapture %command%.
3. (Recommended) Start the game with only Vulkan capture enabled env OBS_VKCAPTURE=1 %command%.

Known Issues

• OpenGL GLX capture doesn't work with NVIDIA driver

Troubleshooting

NVIDIA

Driver version >= 515.43.04 and nvidia-drm.modeset=1 kernel parameter are required.

Multiple GPUs

Try to run both OBS and the game on the same GPU.

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.
