Description

VK_KHR_video_maintenance1 adds a collection of minor video coding features, none of which would warrant an entire extension of their own.

The new features are as follows:

• Allow creating buffers that can be used in video coding operations, independent of the used video profile, using the new buffer creation flag VK_BUFFER_CREATE_VIDEO_PROFILE_INDEPENDENT_BIT_KHR.
• Allow creating images that can be used as decode output or encode input pictures, independent of the used video profile, using the new image creation flag VK_IMAGE_CREATE_VIDEO_PROFILE_INDEPENDENT_BIT_KHR.
• Allow specifying queries used by video coding operations as part of the video coding command parameters, instead of using begin/end query when the video session is created using the new video session creation flag VK_VIDEO_SESSION_CREATE_INLINE_QUERIES_BIT_KHR.

New Structures

• Extending VkPhysicalDeviceFeatures2, VkDeviceCreateInfo:
  • VkPhysicalDeviceVideoMaintenance1FeaturesKHR
• Extending VkVideoDecodeInfoKHR, VkVideoEncodeInfoKHR:
  • VkVideoInlineQueryInfoKHR
