C Specification

Additional information about the video decode use case can be provided by adding a VkVideoDecodeUsageInfoKHR structure to the pNext chain of VkVideoProfileInfoKHR.

The VkVideoDecodeUsageInfoKHR structure is defined as:

// Provided by VK_KHR_video_decode_queue
typedef struct VkVideoDecodeUsageInfoKHR {
    VkStructureType               sType;
    const void*                   pNext;
    VkVideoDecodeUsageFlagsKHR    videoUsageHints;
} VkVideoDecodeUsageInfoKHR;

Members

  • sType is a VkStructureType value identifying this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • videoUsageHints is a bitmask of VkVideoDecodeUsageFlagBitsKHR specifying hints about the intended use of the video decode profile.

Description

Valid Usage (Implicit)

  • VUID-VkVideoDecodeUsageInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_DECODE_USAGE_INFO_KHR

  • VUID-VkVideoDecodeUsageInfoKHR-videoUsageHints-parameter
    videoUsageHints must be a valid combination of VkVideoDecodeUsageFlagBitsKHR values
