C Specification

The VkVideoDecodeH265SessionParametersCreateInfoEXT structure is defined as:

// Provided by VK_EXT_video_decode_h265
typedef struct VkVideoDecodeH265SessionParametersCreateInfoEXT {
    VkStructureType                                        sType;
    const void*                                            pNext;
    uint32_t                                               maxSpsStdCount;
    uint32_t                                               maxPpsStdCount;
    const VkVideoDecodeH265SessionParametersAddInfoEXT*    pParametersAddInfo;
} VkVideoDecodeH265SessionParametersCreateInfoEXT;

Members

  • sType is the type of this structure.

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

  • maxSpsStdCount is the maximum number of SPS parameters that the VkVideoSessionParametersKHR can contain.

  • maxPpsStdCount is the maximum number of PPS parameters that the VkVideoSessionParametersKHR can contain.

  • pParametersAddInfo is NULL or a pointer to a VkVideoDecodeH265SessionParametersAddInfoEXT structure specifying H.265 parameters to add upon object creation.

Description

A VkVideoDecodeH265SessionParametersCreateInfoEXT structure holding one H.265 SPS and at least one H.265 PPS paramater set must be chained to VkVideoSessionParametersCreateInfoKHR when calling vkCreateVideoSessionParametersKHR to store these parameter set(s) with the decoder parameter set object for later reference. The provided H.265 SPS/PPS parameters must be within the limits specified during decoder creation for the decoder specified in VkVideoSessionParametersCreateInfoKHR.

Valid Usage (Implicit)
  • VUID-VkVideoDecodeH265SessionParametersCreateInfoEXT-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_DECODE_H265_SESSION_PARAMETERS_CREATE_INFO_EXT

  • VUID-VkVideoDecodeH265SessionParametersCreateInfoEXT-pParametersAddInfo-parameter
    If pParametersAddInfo is not NULL, pParametersAddInfo must be a valid pointer to a valid VkVideoDecodeH265SessionParametersAddInfoEXT structure
