## Name

vkDestroyVideoSessionKHR - Destroy decode session object

Loading… please wait.

## C Specification

To destroy a decode session object, call:

    // Provided by VK_KHR_video_queue
    void vkDestroyVideoSessionKHR(
        VkDevice                                    device,
        VkVideoSessionKHR                           videoSession,
        const VkAllocationCallbacks*                pAllocator);

## Parameters

- `device` is the device that was used for the creation of the video session.

- `videoSession` is the decode or encode video session to be destroyed.

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

## Description

Valid Usage (Implicit)

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

- VUID-vkDestroyVideoSessionKHR-videoSession-parameter
  If `videoSession` is not VK_NULL_HANDLE, `videoSession` must be a valid VkVideoSessionKHR handle

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

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

Host Synchronization

- Host access to `videoSession` must be externally synchronized
