## Name

vkDestroyVideoSessionParametersKHR - Destroy video session parameters object

Loading… please wait.

## C Specification

To destroy a video session parameters object, call:

    // Provided by VK_KHR_video_queue
    void vkDestroyVideoSessionParametersKHR(
        VkDevice                                    device,
        VkVideoSessionParametersKHR                 videoSessionParameters,
        const VkAllocationCallbacks*                pAllocator);

## Parameters

- `device` is the logical device that destroys the video session parameters object.

- `videoSessionParameters` is the video session parameters object to destroy.

- `pAllocator` controls host memory allocation as described in the Memory Allocation chapter.

## Description

Valid Usage

- VUID-vkDestroyVideoSessionParametersKHR-videoSessionParameters-07212
  All submitted commands that refer to `videoSessionParameters` must have completed execution

- VUID-vkDestroyVideoSessionParametersKHR-videoSessionParameters-07213
  If `VkAllocationCallbacks` were provided when `videoSessionParameters` was created, a compatible set of callbacks must be provided here

- VUID-vkDestroyVideoSessionParametersKHR-videoSessionParameters-07214
  If no `VkAllocationCallbacks` were provided when `videoSessionParameters` was created, `pAllocator` must be `NULL`

Valid Usage (Implicit)

- VUID-vkDestroyVideoSessionParametersKHR-device-parameter
  `device` must be a valid VkDevice handle

- VUID-vkDestroyVideoSessionParametersKHR-videoSessionParameters-parameter
  If `videoSessionParameters` is not VK_NULL_HANDLE, `videoSessionParameters` must be a valid VkVideoSessionParametersKHR handle

- VUID-vkDestroyVideoSessionParametersKHR-pAllocator-parameter
  If `pAllocator` is not `NULL`, `pAllocator` must be a valid pointer to a valid VkAllocationCallbacks structure

- VUID-vkDestroyVideoSessionParametersKHR-videoSessionParameters-parent
  If `videoSessionParameters` is a valid handle, it must have been created, allocated, or retrieved from `device`

Host Synchronization

- Host access to `videoSessionParameters` must be externally synchronized
