C Specification

The VkVideoProfileListInfoKHR structure is defined as:

// Provided by VK_KHR_video_queue
typedef struct VkVideoProfileListInfoKHR {
    VkStructureType                 sType;
    const void*                     pNext;
    uint32_t                        profileCount;
    const VkVideoProfileInfoKHR*    pProfiles;
} VkVideoProfileListInfoKHR;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • profileCount is the number of elements in the pProfiles array.

  • pProfiles is a pointer to an array of VkVideoProfileInfoKHR structures.

Description

Note:

Video transcoding is an example of a use case that necessitates the specification of multiple profiles in various contexts.

When the application provides a video decode profile and one or more video encode profiles in the profile list, the implementation ensures that any capabilitities returned or resources created are suitable for the video transcoding use cases without the need for manual data transformations.

Valid Usage

  • VUID-VkVideoProfileListInfoKHR-pProfiles-06813
    pProfiles must not contain more than one element whose videoCodecOperation member specifies a decode operation

Valid Usage (Implicit)

  • VUID-VkVideoProfileListInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_PROFILE_LIST_INFO_KHR

  • VUID-VkVideoProfileListInfoKHR-pProfiles-parameter
    If profileCount is not 0, pProfiles must be a valid pointer to an array of profileCount valid VkVideoProfileInfoKHR structures
