## Name

VkVideoEncodeSessionParametersGetInfoKHR - Structure specifying parameters for retrieving encoded video session parameter data

Loading… please wait.

## C Specification

The `VkVideoEncodeSessionParametersGetInfoKHR` structure is defined as:

    // Provided by VK_KHR_video_encode_queue
    typedef struct VkVideoEncodeSessionParametersGetInfoKHR {
        VkStructureType                sType;
        const void*                    pNext;
        VkVideoSessionParametersKHR    videoSessionParameters;
    } VkVideoEncodeSessionParametersGetInfoKHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

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

- `videoSessionParameters` is the VkVideoSessionParametersKHR object to retrieve encoded parameter data from.

## Description

Depending on the used video encode operation, additional codec-specific structures may need to be included in the `pNext` chain of this structure to identify the specific video session parameters to retrieve encoded parameter data for, as described in the corresponding sections.

Valid Usage (Implicit)

- VUID-VkVideoEncodeSessionParametersGetInfoKHR-sType-sType
  `sType` must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_SESSION_PARAMETERS_GET_INFO_KHR

- VUID-VkVideoEncodeSessionParametersGetInfoKHR-pNext-pNext
  Each `pNext` member of any structure (including this one) in the `pNext` chain must be either `NULL` or a pointer to a valid instance of VkVideoEncodeH264SessionParametersGetInfoKHR or VkVideoEncodeH265SessionParametersGetInfoKHR

- VUID-VkVideoEncodeSessionParametersGetInfoKHR-sType-unique
  The `sType` value of each structure in the `pNext` chain must be unique

- VUID-VkVideoEncodeSessionParametersGetInfoKHR-videoSessionParameters-parameter
  `videoSessionParameters` must be a valid VkVideoSessionParametersKHR handle
