C Specification

The VkVideoEncodeH264SessionParametersGetInfoKHR structure is defined as:

// Provided by VK_KHR_video_encode_h264
typedef struct VkVideoEncodeH264SessionParametersGetInfoKHR {
    VkStructureType    sType;
    const void*        pNext;
    VkBool32           writeStdSPS;
    VkBool32           writeStdPPS;
    uint32_t           stdSPSId;
    uint32_t           stdPPSId;
} VkVideoEncodeH264SessionParametersGetInfoKHR;

Members

  • sType is a VkStructureType value identifying this structure.

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

  • writeStdSPS indicates whether the encoded H.264 sequence parameter set identified by stdSPSId is requested to be retrieved.

  • writeStdPPS indicates whether the encoded H.264 picture parameter set identified by the pair constructed from stdSPSId and stdPPSId is requested to be retrieved.

  • stdSPSId specifies the H.264 sequence parameter set ID used to identify the retrieved H.264 sequence and/or picture parameter set(s).

  • stdPPSId specifies the H.264 picture parameter set ID used to identify the retrieved H.264 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.264 sequence parameter set identified by stdSPSId, if writeStdSPS is set to VK_TRUE.

  2. The H.264 picture parameter set identified by the pair constructed from stdSPSId and stdPPSId, if writeStdPPS is set to VK_TRUE.

Valid Usage

  • VUID-VkVideoEncodeH264SessionParametersGetInfoKHR-writeStdSPS-08279
    At least one of writeStdSPS and writeStdPPS must be set to VK_TRUE

Valid Usage (Implicit)

  • VUID-VkVideoEncodeH264SessionParametersGetInfoKHR-sType-sType
    sType must be VK_STRUCTURE_TYPE_VIDEO_ENCODE_H264_SESSION_PARAMETERS_GET_INFO_KHR
