C Specification

The VkVideoCodingControlInfoKHR structure is defined as:

// Provided by VK_KHR_video_queue
typedef struct VkVideoCodingControlInfoKHR {
    VkStructureType                 sType;
    const void*                     pNext;
    VkVideoCodingControlFlagsKHR    flags;
} VkVideoCodingControlInfoKHR;

Members

  • sType is the type of this structure.

  • pNext is NULL or a pointer to a structure extending this structure.

  • flags is a bitmask of VkVideoCodingControlFlagsKHR specifying control flags.

Description

Valid Usage

  • VUID-VkVideoCodingControlInfoKHR-flags-07018
    If flags includes VK_VIDEO_CODING_CONTROL_ENCODE_RATE_CONTROL_BIT_KHR, then the pNext chain must include a VkVideoEncodeRateControlInfoKHR structure

  • VUID-VkVideoCodingControlInfoKHR-flags-07019
    If flags includes VK_VIDEO_CODING_CONTROL_ENCODE_RATE_CONTROL_LAYER_BIT_KHR, then the pNext chain must include a VkVideoEncodeRateControlLayerInfoKHR structure

  • VUID-VkVideoCodingControlInfoKHR-flags-07020
    If flags includes VK_VIDEO_CODING_CONTROL_ENCODE_RATE_CONTROL_BIT_KHR, then it must not also include VK_VIDEO_CODING_CONTROL_ENCODE_RATE_CONTROL_LAYER_BIT_KHR

  • VUID-VkVideoCodingControlInfoKHR-flags-07021
    If flags includes VK_VIDEO_CODING_CONTROL_ENCODE_RATE_CONTROL_BIT_KHR, the rateControlMode member of VkVideoEncodeRateControlInfoKHR included in the pNext chain is not VK_VIDEO_ENCODE_RATE_CONTROL_MODE_DEFAULT_KHR or VK_VIDEO_ENCODE_RATE_CONTROL_MODE_DISABLED_BIT_KHR, and the bound video session was created with the video codec operation VK_VIDEO_CODEC_OPERATION_ENCODE_H264_BIT_EXT, then the pNext chain must include a VkVideoEncodeH264RateControlInfoEXT structure

  • VUID-VkVideoCodingControlInfoKHR-pNext-07022
    If the pNext chain includes a VkVideoEncodeRateControlInfoKHR, and VkVideoEncodeRateControlInfoKHR::layerCount is greater than 1, then VkVideoEncodeH264RateControlInfoEXT::temporalLayerCount must be equal to layerCount

  • VUID-VkVideoCodingControlInfoKHR-flags-07023
    If flags includes VK_VIDEO_CODING_CONTROL_ENCODE_RATE_CONTROL_LAYER_BIT_KHR and the bound video session was created with the video codec operation VK_VIDEO_CODEC_OPERATION_ENCODE_H264_BIT_EXT, then the pNext chain must include a VkVideoEncodeH264RateControlLayerInfoEXT structure

  • VUID-VkVideoCodingControlInfoKHR-flags-07024
    If flags includes VK_VIDEO_CODING_CONTROL_ENCODE_RATE_CONTROL_BIT_KHR, the rateControlMode member of VkVideoEncodeRateControlInfoKHR included in the pNext chain is not VK_VIDEO_ENCODE_RATE_CONTROL_MODE_DEFAULT_KHR or VK_VIDEO_ENCODE_RATE_CONTROL_MODE_DISABLED_BIT_KHR, and the bound video session was created with the video codec operation VK_VIDEO_CODEC_OPERATION_ENCODE_H265_BIT_EXT, then the pNext chain must include a VkVideoEncodeH265RateControlInfoEXT structure

  • VUID-VkVideoCodingControlInfoKHR-pNext-07025
    If the pNext chain includes a VkVideoEncodeRateControlInfoKHR, and VkVideoEncodeRateControlInfoKHR::layerCount is greater than 1, then VkVideoEncodeH265RateControlInfoEXT::subLayerCount must be equal to layerCount

  • VUID-VkVideoCodingControlInfoKHR-flags-07026
    If flags includes VK_VIDEO_CODING_CONTROL_ENCODE_RATE_CONTROL_LAYER_BIT_KHR and the bound video session was created with the video codec operation VK_VIDEO_CODEC_OPERATION_ENCODE_H265_BIT_EXT, then the pNext chain must include a VkVideoEncodeH265RateControlLayerInfoEXT structure
