## Name

vkBindOpticalFlowSessionImageNV - Bind image to an optical flow session

Loading… please wait.

## C Specification

To bind a vulkan image to an optical flow session object, call:

    // Provided by VK_NV_optical_flow
    VkResult vkBindOpticalFlowSessionImageNV(
        VkDevice                                    device,
        VkOpticalFlowSessionNV                      session,
        VkOpticalFlowSessionBindingPointNV          bindingPoint,
        VkImageView                                 view,
        VkImageLayout                               layout);

## Parameters

- `device` is the device which owns the optical flow session object `session`.

- `session` is the optical flow session object to which the image view is to be bound.

- `bindingPoint` specifies the binding point VkOpticalFlowSessionBindingPointNV to which the image view is bound.

- `view` is a VkImageView to be bound.

- layout must specify the layout that the image subresources accessible from `view` will be in at the time the optical flow vectors are calculated with vkCmdOpticalFlowExecuteNV on a `VkDevice`.

## Description

Valid Usage (Implicit)

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

- VUID-vkBindOpticalFlowSessionImageNV-session-parameter
  `session` must be a valid VkOpticalFlowSessionNV handle

- VUID-vkBindOpticalFlowSessionImageNV-bindingPoint-parameter
  `bindingPoint` must be a valid VkOpticalFlowSessionBindingPointNV value

- VUID-vkBindOpticalFlowSessionImageNV-view-parameter
  If `view` is not VK_NULL_HANDLE, `view` must be a valid VkImageView handle

- VUID-vkBindOpticalFlowSessionImageNV-layout-parameter
  `layout` must be a valid VkImageLayout value

- VUID-vkBindOpticalFlowSessionImageNV-session-parent
  `session` must have been created, allocated, or retrieved from `device`

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

Return Codes

On success, this command returns

  - `VK_SUCCESS`

On failure, this command returns

  - `VK_ERROR_OUT_OF_HOST_MEMORY`

  - `VK_ERROR_INITIALIZATION_FAILED`
