C Specification

The VkVideoEncodeH265SessionParametersCreateInfoEXT structure is defined as:

// Provided by VK_EXT_video_encode_h265
typedef struct VkVideoEncodeH265SessionParametersCreateInfoEXT {
    VkStructureType                                        sType;
    const void*                                            pNext;
    uint32_t                                               maxVpsStdCount;
    uint32_t                                               maxSpsStdCount;
    uint32_t                                               maxPpsStdCount;
    const VkVideoEncodeH265SessionParametersAddInfoEXT*    pParametersAddInfo;
} VkVideoEncodeH265SessionParametersCreateInfoEXT;

Members

  • sType is the type of this structure.

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

  • maxVpsStdCount is the maximum number of entries of type StdVideoH265VideoParameterSet within VkVideoSessionParametersKHR.

  • maxSpsStdCount is the maximum number of entries of type StdVideoH265SequenceParameterSet within VkVideoSessionParametersKHR.

  • maxPpsStdCount is the maximum number of entries of type StdVideoH265PictureParameterSet within VkVideoSessionParametersKHR.

  • pParametersAddInfo is NULL or a pointer to a VkVideoEncodeH265SessionParametersAddInfoEXT structure specifying the video session parameters to add upon creation of this object.

Description

When a VkVideoSessionParametersKHR object contains maxVpsStdCount StdVideoH265VideoParameterSet entries, no additional StdVideoH265VideoParameterSet entries can be added to it, and VK_ERROR_TOO_MANY_OBJECTS will be returned if an attempt is made to add these entries. When a VkVideoSessionParametersKHR object contains maxSpsStdCount StdVideoH265SequenceParameterSet entries, no additional StdVideoH265SequenceParameterSet entries can be added to it, and VK_ERROR_TOO_MANY_OBJECTS will be returned if an attempt is made to add these entries. When a VkVideoSessionParametersKHR object contains maxPpsStdCount StdVideoH265PictureParameterSet entries, no additional StdVideoH265PictureParameterSet entries can be added to it, and VK_ERROR_TOO_MANY_OBJECTS will be returned if an attempt is made to add these entries.

Valid Usage (Implicit)

  • VUID-VkVideoEncodeH265SessionParametersCreateInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H265_SESSION_PARAMETERS_CREATE_INFO_EXT

  • VUID-VkVideoEncodeH265SessionParametersCreateInfoEXT-pParametersAddInfo-parameter
    If pParametersAddInfo is not NULL, pParametersAddInfo must be a valid pointer to a valid VkVideoEncodeH265SessionParametersAddInfoEXT structure
