# vkCmdControlVideoCodingKHR(3) Manual Page

## Name

vkCmdControlVideoCodingKHR - set encode rate control parameters

Loading… please wait.

## C Specification

To apply dynamic controls to video decode or video operations, call:

    // Provided by VK_KHR_video_queue
    void vkCmdControlVideoCodingKHR(
        VkCommandBuffer                             commandBuffer,
        const VkVideoCodingControlInfoKHR*          pCodingControlInfo);

## Parameters

- `commandBuffer` is the command buffer to be filled by this function for setting encode rate control parameters.

- `pCodingControlInfo` is a pointer to VkVideoCodingControlInfoKHR.

## Description

Valid Usage (Implicit)

- VUID-vkCmdControlVideoCodingKHR-commandBuffer-parameter
  `commandBuffer` must be a valid VkCommandBuffer handle

- VUID-vkCmdControlVideoCodingKHR-pCodingControlInfo-parameter
  `pCodingControlInfo` must be a valid pointer to a valid VkVideoCodingControlInfoKHR structure

- VUID-vkCmdControlVideoCodingKHR-commandBuffer-recording
  `commandBuffer` must be in the recording state

- VUID-vkCmdControlVideoCodingKHR-commandBuffer-cmdpool
  The `VkCommandPool` that `commandBuffer` was allocated from must support decode, or encode operations

- VUID-vkCmdControlVideoCodingKHR-renderpass
  This command must only be called outside of a render pass instance

- VUID-vkCmdControlVideoCodingKHR-bufferlevel
  `commandBuffer` must be a primary `VkCommandBuffer`

Host Synchronization

- Host access to the `VkCommandPool` that `commandBuffer` was allocated from must be externally synchronized

Command Properties

Command Buffer Levels | Render Pass Scope | Supported Queue Types | Pipeline Type
--- | --- | --- | ---
Primary | Outside | Decode Encode |
