In April 2021, the Vulkan® Working Group at Khronos® released a set of provisional extensions, collectively referred to as ‘Vulkan Video’ which provide seamless encoding and decoding of video streams using a variety of video coding standards. The December 2022 release of Vulkan 1.3.238 saw the finalization of the extensions to decode H.264 and H.265, and today, with the release of Vulkan 1.3.274, Khronos has finalized their counterpart: the extensions to enable encoding of H.264 and H.265 video streams. Leveraging the Vulkan framework, they provide a standardized, seamless, low-overhead, and highly controllable way to produce H.264 and H.265 video via hardware accelerators, with applications ranging from real-time, low-latency streaming to offline server-scale transcoding.

In a world where 3D content creation and distribution are rapidly evolving, the need for seamless interoperability and shared standards has never been more critical. That's why the Alliance for OpenUSD (AOUSD) and Khronos Group have signed a liaison agreement to align and enhance OpenUSD and glTF technologies. This liaison marks a significant step towards unified 3D asset creation and deployment, streamlining the process for developers and end-users alike.

SYnergy research project enables energy efficient C++ based heterogeneous parallel programming with the Khronos SYCL API In high performance computing, creating energy efficiencies has become critical - from the design of cooling systems to the development of low-power hardware architectures. Processor hardware can help reduce power consumption by using dynamic voltage and frequency scaling.  Many GPU vendors provide APIs to take

glTF is the most portable and accessible asset format for bringing 3D content to diverse platforms, including the web. This open, royalty-free specification minimizes the runtime processing to unpack and process 3D assets, while also supporting sophisticated graphics functionality, rich textures, and diverse materials. Broad industry support for glTF includes adoption of glTF 2.0 as an ISO/IEC International Standard. Now, Khronos is pleased to announce an open-source native iOS app, “Khronos glTF Viewer,” that enables users to view and interact with glTF assets on iOS devices, including in AR. This app is distinct from the glTF Sample Viewer, the official browser-based reference viewer from Khronos. Rather, it is squarely focused on bringing glTF viewing capabilities to iOS devices, bridging a crucial gap for the “JPEG of 3D” and hastening a future where content creators can deploy glTF assets on any target platform. “Khronos glTF Viewer” is live on the Apple App Store with source code immediately available on GitHub under the Apache 2.0 license; developer participation and feedback is welcome
