C Specification

To attach memory to a video session object, call:

// Provided by VK_KHR_video_queue
VkResult vkBindVideoSessionMemoryKHR(
    VkDevice                                    device,
    VkVideoSessionKHR                           videoSession,
    uint32_t                                    videoSessionBindMemoryCount,
    const VkVideoBindMemoryKHR*                 pVideoSessionBindMemories);


  • device is the logical device that owns the video session’s memory.

  • videoSession is the video session to be bound with device memory.

  • videoSessionBindMemoryCount is the number of pVideoSessionBindMemories to be bound.

  • pVideoSessionBindMemories is a pointer to an array of VkVideoBindMemoryKHR structures specifying memory regions to be bound to a device memory heap.


Valid Usage (Implicit)
  • VUID-vkBindVideoSessionMemoryKHR-device-parameter
    device must be a valid VkDevice handle

  • VUID-vkBindVideoSessionMemoryKHR-videoSession-parameter
    videoSession must be a valid VkVideoSessionKHR handle

  • VUID-vkBindVideoSessionMemoryKHR-pVideoSessionBindMemories-parameter
    pVideoSessionBindMemories must be a valid pointer to an array of videoSessionBindMemoryCount valid VkVideoBindMemoryKHR structures

  • VUID-vkBindVideoSessionMemoryKHR-videoSessionBindMemoryCount-arraylength
    videoSessionBindMemoryCount must be greater than 0

  • VUID-vkBindVideoSessionMemoryKHR-videoSession-parent
    videoSession must have been created, allocated, or retrieved from device
