C Specification

The VkVideoEncodeSessionParametersGetInfoKHR structure is defined as:

// Provided by VK_KHR_video_encode_queue
typedef struct VkVideoEncodeSessionParametersGetInfoKHR {
    VkStructureType                sType;
    const void*                    pNext;
    VkVideoSessionParametersKHR    videoSessionParameters;
} VkVideoEncodeSessionParametersGetInfoKHR;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • videoSessionParameters is the VkVideoSessionParametersKHR object to retrieve encoded parameter data from.

Description

Depending on the used video encode operation, additional codec-specific structures may need to be included in the pNext chain of this structure to identify the specific video session parameters to retrieve encoded parameter data for, as described in the corresponding sections.

Valid Usage (Implicit)

  • VUID-VkVideoEncodeSessionParametersGetInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_SESSION_PARAMETERS_GET_INFO_KHR

  • VUID-VkVideoEncodeSessionParametersGetInfoKHR-pNext-pNext
    Each pNext member of any structure (including this one) in the pNext chain must be either NULL or a pointer to a valid instance of VkVideoEncodeH264SessionParametersGetInfoKHR or VkVideoEncodeH265SessionParametersGetInfoKHR

  • VUID-VkVideoEncodeSessionParametersGetInfoKHR-sType-unique
    The sType value of each struct in the pNext chain must be unique

  • VUID-VkVideoEncodeSessionParametersGetInfoKHR-videoSessionParameters-parameter
    videoSessionParameters must be a valid VkVideoSessionParametersKHR handle
