## Name

VkVideoProfileListInfoKHR - Structure specifying one or more video profiles used in conjunction

Loading… please wait.

## 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
