Today, with the release of Vulkan 1.3.302, Khronos is proud to announce two new Vulkan Video encode extensions. First, the highly anticipated Encode AV1 extension enhances Vulkan Video by adding AV1 encode functionality to complement its existing AV1 decode support. This milestone means that Vulkan Video now provides full decode AND encode acceleration for the H.264, H.265 and AV1 codec standards. Additionally, the new Encode Quantization Map extension introduces advanced encoding features for all supported codecs to Vulkan Video developers for the first time. We are confident these extensions provide the necessary building blocks for your advanced Vulkan Video applications!

The open-source Intel "ANV" Vulkan driver within Mesa is now more capable for its Vulkan Video support with the H.264 and H.265 encode support now wired up for Mesa 24.3.

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.

Nsight Graphics 2022.7 is available now, adding support for the finalized release of Vulkan Video decode. You can frame capture applications that use Vulkan Video to inspect events and resource allocation.

Vulkan Video gives developers the choice of a powerful new API for accessing video processing acceleration. NVIDIA is expanding its commitment to Vulkan Video with tools and samples to help applications efficiently harness this significant new functionality. In this NVIDIA blog post, they will help you discover whether Vulkan Video is right for your application—and if so, how to get started.

The Khronos Group announces that LunarG has released the Vulkan Software Development Kit (SDK) version 1.3.239.0 for Windows and Linux with full support for the four Vulkan Video extensions finalized in December 2022, including header upgrades and Validation Layer integration. Together with drivers shipping from multiple GPU vendors, developers are now equipped with the essential tools to use Vulkan Video-accelerated H.264 and H.265 decode in frameworks and applications.

In April 2021, the Vulkan® Working Group at Khronos® released a set of provisional extensions, collectively called ‘Vulkan Video’, for seamlessly integrating hardware-accelerated video compression and decompression into the Vulkan API. Today, Khronos is releasing finalized extensions that incorporate industry feedback and expose core and decode Vulkan Video functionality to provide fully accelerated H.264 and H.265 decode.

Khronos will release an ongoing series of Vulkan Video extensions to enable additional codecs and accelerated encode as well as decode. This blog is a general overview of the Vulkan Video architecture and also provides details about the finalized extensions and links to important resources to help you create your first Vulkan Video applications.

The Khronos Group BOF day is today, July 31. For those folks that really wanted to catch some of the BOF Day sessions, but couldn't make, we have it covered for you. Starting at 9AM PT, the morning livestream will start on YouTube. The afternoon sessions will be on a second afternoon livestream also on YouTube. Learn more about the Khronos Group BOF Day and all of the various sessions on our SIGGRAPH 2019 event page.

All of the presentations and videos from the Khronos OpenVX workshop at the 2019 Embedded Vision Summit are now online. If you were unable to attend this workshop, you may now watch the seven sessions online and follow along with the slide presentations:

• Introduction and OpenCL Overview & Update – Neil Trevett, NVIDIA: slides, video
• OpenCL & SYCL – Andrew Richards, Codeplay: slides, video

This week, Neil Trevett spoke at the 2019 Open AR Cloud Symposium. Neil's presentation focused on OpenXR and glTF covering how these Open Standards fit into the rest of the Khronos Ecosystem. Presentation slides and video are available online.

Neil Trevett, President of the Khronos Group, delivers the presentation “Update on Khronos Standards for Vision and Machine Learning” at the Embedded Vision Alliance’s September 2018 Vision Industry and Technology Forum. Neil Trevett shares updates on recent, current and planned Khronos standardization activities aimed at streamlining the deployment of embedded vision and AI.

In this talk from the 2018 Game Dev Days, Jörg Müller answers questions you may have about the Vulkan API. with the knowledge and experience I gained during over a year of using it. Jörg is currently a PhD student at the Insitute for Computer Graphics and Vision at Graz University of Technology under the supervision of Ass. Prof. Markus Steinberger and Prof. Dieter Schmalstieg. From 2015 to 2016 Jörg worked as a researcher in the Advanced Concepts Team of the European Space Agency in the field of Artificial Intelligence.

SIGGRAPH is next week! The conference is August 12–16 in Vancouver Canada. For those going, Khronos will be hosting several Birds of a Feather sessions. For all those folks that will not be present, we will be offering live streaming of all our sessions (glTF, WebGL, OpenXR, Vulkan and OpenGL) on the Khronos Group YouTube Channel, and will follow up with recorded video the following week. For complete details on all the sessions, please ask your friends and co-workers to take a look at our SIGGRAPH event page! A special thanks to our Diamond sponsor NVIDIA, Gold Sponsor LunarG, and Silver sponsors Cesium and AMD, for making possible the Khronos Networking Reception at the end of the day.

Khronos hosted a webinar on July 31st covering "glTF 2.0 – Status and Outlook." If you missed the webinar, which was hosted by Nobert Nopper from UX3D, we have you covered with the video and presentations available online. All the links are in our Developer Library here.

Be sure to also watch the Khronos workshop from the Embedded Vision summit. Video and Presentation slides are online. For the full version of this video, along with hundreds of others on various embedded vision topics, please visit the Embedded Vision website.
