OBS Linux Vulkan/OpenGL game capture

OBS plugin for Vulkan/OpenGL game capture on Linux.

Requires OBS >= 27. On X11 you need to explicitly enable EGL: OBS_USE_EGL=1 obs.

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)

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

• Vulkan capture requires VK_EXT_external_memory_dma_buf (NVIDIA driver >= 515.43.04)
• OpenGL GLX capture doesn't work with NVIDIA driver

Troubleshooting

Cannot create EGLImage: Arguments are inconsistent

If you get this error with Vulkan capture, try starting the game with OBS_VKCAPTURE_LINEAR=1 environment variable.

No Game Capture source available in OBS

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