C Specification

To destroy a video session, call:

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

Parameters

  • device is the logical device that destroys the video session.

  • videoSession is the video session to destroy.

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

Description

Valid Usage

  • VUID-vkDestroyVideoSessionKHR-videoSession-07192
    All submitted commands that refer to videoSession must have completed execution

  • VUID-vkDestroyVideoSessionKHR-videoSession-07193
    If VkAllocationCallbacks were provided when videoSession was created, a compatible set of callbacks must be provided here

  • VUID-vkDestroyVideoSessionKHR-videoSession-07194
    If no VkAllocationCallbacks were provided when videoSession was created, pAllocator must be NULL

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
