New Vulkan SDKs include provisional Video Support and other new extensions

LunarG releases new Windows, Linux, and macOS SDKs for Vulkan header 1.2.176. These SDKs include support for many new extensions, including provisional Video. The prior SDK supported Vulkan API revision 1.2.170.  Read on for information about the new extensions.

Overview of new extensions in Vulkan SDK

The Vulkan headers now include the following new extensions. Note that extensions are optional and may not be implemented by the underlying driver/ICD. Applications can now query for the presence of these new features.

  • VK_EXT_extended_dynamic_state2
  • VK_EXT_color_write_enable
  • VK_EXT_vertex_input_dynamic_state
  • VK_EXT_ycbcr_2plane_444_format
  • VK_NV_inherited_viewport_scissor
  • VK_KHR_video_queue
  • VK_KHR_video_decode_queue
  • VK_KHR_video_encode_queue
  • VK_EXT_video_decode_h264
  • VK_EXT_video_decode_h265
  • VK_EXT_video_encode_h264
  • VK_FUCHSIA_external_memory
  • VK_FUCHSIA_external_semaphore
  • VK_QNX_screen_surface

The API interface library for the DirectX Shader Compiler has been added to the SDK. In addition, the Vulkan Configurator (vkconfig) has been updated to improve quality and stability. See the Vulkan Configurator documentation for more information.

macOS Updates

The macOS version of the SDK has been updated to MoltenVK version 1.1.3 with the following highlights:

  • Added support for HDR10 colorspace via VK_COLOR_SPACE_HDR10_HLG_EXT and VK_COLOR_SPACE_HDR10_ST2084_EXT
  • Always explicitly set CAMetalLayer colorspace property based on Vulkan parameters, not Metal default values
  • Fixed MVKPhysicalDevice::getSurfaceFormats() returning VK_FORMAT_UNDEFINED
  • Log enhanced command buffer errors in debug mode
  • Updated to latest SPIRV-Cross version
