Texture Sharing between Vulkan and OpenGL instances

An API to share GPU texture memory between processes. Can be used to exchange images without performing a CPU roundtrip.

Available implementations:

• Godot: https://github.com/DigitOtter/gd_texture_share_vk.git
• OBS: https://github.com/DigitOtter/obs-plugin-texture-share-vk.git

Build

Linux

• Download repository
• Execute inside the repository directory:

  git submodule update --init --recursive
  cmake -S . -B build -DCMAKE_BUILD_TYPE=Release -GNinja
  cmake --build build
  sudo cmake --install build

Windows

• Currently not supported (I'd recommend using Spout2 on Windows)

Installation

Linux

Arch Linux

Available via the texture-share-vk-git AUR package:

pikaur -S texture-share-vk-git

Todos

• Documentation
• Fallback to sharing RAM memory if GPU does not support texture sharing or if Vulkan/OpenGL instances are running on different GPUs
• Maybe Windows version
