Consequently Vulkan Video adds video decode and encode queues, the presence of which can be queried by using VkQueueFlagBits.Īlso, the field of video codecs is continuously evolving, enabling ever more efficient video compression and decompression through increasingly advanced and domain-specific video coding tools-resulting in new codecs and codec extensions. In fact, some physical devices may support only video decode and/or video encode operations. GPUs typically contain dedicated video decode and encode acceleration engine(s) that are independent from other graphics and compute engines. We invite all developers to provide feedback so the finalized Vulkan Video 1.0 extensions can be finely tuned to provide exciting new capabilities for Vulkan applications everywhere! Vulkan Video Extensions Overview The Provisional Vulkan Video extensions closely integrate hardware accelerated video processing with Vulkan’s existing graphics, compute and display functionality. This will be complemented by open source Vulkan Video samples for a range of application use cases on Windows and Linux. To complement the low-level design of Vulkan Video, Khronos plans to add support in the Vulkan SDK with layers for validation and higher-level abstractions that will speed the development of video applications where simple frame-in-frame-out and black-box decoding and encoding is sufficient. Stages in typical Vulkan Video decode and encode applications Leveraging the existing Vulkan framework enables efficient, low-latency, low-overhead use of processing resources, including distributing stream processing tasks across multiple CPU cores and video codec hardware-all with application portability across multiple platforms and devices ranging from small embedded devices to high performance servers. Vulkan Video adheres to the Vulkan philosophy of providing flexible, fine-grained control over video processing scheduling, synchronization, and memory utilization to the application. This blog will give you an overview of Vulkan’s new video processing capabilities and we welcome feedback before the extensions are finalized so that they may provide effective acceleration for your video applications! Today, Khronos is releasing a set of Provisional Vulkan Video acceleration extensions : ‘Vulkan Video’. In early 2018 the Vulkan Working Group at Khronos started to explore how to seamlessly integrate hardware accelerated video compression and decompression into the Vulkan API.
