C Specification

The VkVideoEncodeH265SessionParametersGetInfoKHR structure is defined as:

// Provided by VK_KHR_video_encode_h265
typedef struct VkVideoEncodeH265SessionParametersGetInfoKHR {
    VkStructureType    sType;
    const void*        pNext;
    VkBool32           writeStdVPS;
    VkBool32           writeStdSPS;
    VkBool32           writeStdPPS;
    uint32_t           stdVPSId;
    uint32_t           stdSPSId;
    uint32_t           stdPPSId;
} VkVideoEncodeH265SessionParametersGetInfoKHR;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • writeStdVPS indicates whether the encoded H.265 video parameter set identified by stdVPSId is requested to be retrieved.

  • writeStdSPS indicates whether the encoded H.265 sequence parameter set identified by the pair constructed from stdVPSId and stdSPSId is requested to be retrieved.

  • writeStdPPS indicates whether the encoded H.265 picture parameter set identified by the triplet constructed from stdVPSId, stdSPSId, and stdPPSId is requested to be retrieved.

  • stdVPSId specifies the H.265 video parameter set ID used to identify the retrieved H.265 video, sequence, and/or picture parameter set(s).

  • stdSPSId specifies the H.265 sequence parameter set ID used to identify the retrieved H.265 sequence and/or picture parameter set(s) when writeStdSPS and/or writeStdPPS is set to VK_TRUE.

  • stdPPSId specifies the H.265 picture parameter set ID used to identify the retrieved H.265 picture parameter set when writeStdPPS is set to VK_TRUE.

Description

When this structure is specified in the pNext chain of the VkVideoEncodeSessionParametersGetInfoKHR structure passed to vkGetEncodedVideoSessionParametersKHR, the command will write encoded parameter data to the output buffer in the following order:

  1. The H.265 video parameter set identified by stdVPSId, if writeStdVPS is set to VK_TRUE.

  2. The H.265 sequence parameter set identified by the pair constructed from stdVPSId and stdSPSId, if writeStdSPS is set to VK_TRUE.

  3. The H.265 picture parameter set identified by the triplet constructed from stdVPSId, stdSPSId, and stdPPSId, if writeStdPPS is set to VK_TRUE.

Valid Usage

  • VUID-VkVideoEncodeH265SessionParametersGetInfoKHR-writeStdVPS-08290
    At least one of writeStdVPS, writeStdSPS, and writeStdPPS must be set to VK_TRUE

Valid Usage (Implicit)

  • VUID-VkVideoEncodeH265SessionParametersGetInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H265_SESSION_PARAMETERS_GET_INFO_KHR
