## Name

VkVideoProfileListInfoKHR - Structure enumerating the video profiles

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 the type of this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `profileCount` is an integer which holds the number of video profiles included in `pProfiles`.

- `pProfiles` is a pointer to an array of VkVideoProfileInfoKHR structures. Each VkVideoProfileInfoKHR structure must chain the corresponding codec-operation specific extension video profile structure.

## Description

Video transcoding is an example of a use case that necessitates numerous profiles. When the application provides one or more video decode and encode profiles in the list of profiles, the implementation ensures that the video formats and parameters reported produce video resources suitable for the transcoding use cases without the need for manual transformation.

Valid Usage

- VUID-VkVideoProfileListInfoKHR-pProfiles-06813
  If the `pProfiles` list contains more than one VkVideoProfileInfoKHR entry, then it must not contain more than one entry 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
