New Vulkan SDKs Add Four Video Extensions

Today, LunarG released new Windows, Linux, and macOS SDKs for Vulkan header 1.3.239, with four new video decode extensions and additional updates. These new extensions provide fully accelerated H.264 and H.265 decode and enable “efficient, low-latency, low-overhead use of processing resources.” This SDK also includes Validation Layer support for the new video decode extensions.

Additional SDK Updates for All OSs

  • The Vulkan Configurator (vkconfig) has been updated to improve quality and stability.
  • Improved validation coverage. VUID validation coverage documentation (validation_error_database.csv and validation_error_database.html) has been updated to represent the validation layer VUID coverage status.

macOS-Specific SDK Updates

  • The SDK has been updated to MoltenVK version 1.2.2!
