# VkVideoDecodeH264InlineSessionParametersInfoKHR(3) Manual Page

## Name

VkVideoDecodeH264InlineSessionParametersInfoKHR - Structure specifies inline H.264 decoder parameter set information

Loading… please wait.

## C Specification

The `VkVideoDecodeH264InlineSessionParametersInfoKHR` structure is defined as:

    // Provided by VK_KHR_video_decode_h264 with VK_KHR_video_maintenance2
    typedef struct VkVideoDecodeH264InlineSessionParametersInfoKHR {
        VkStructureType                            sType;
        const void*                                pNext;
        const StdVideoH264SequenceParameterSet*    pStdSPS;
        const StdVideoH264PictureParameterSet*     pStdPPS;
    } VkVideoDecodeH264InlineSessionParametersInfoKHR;

## Members

- `sType` is a VkStructureType value identifying this structure.

- `pNext` is `NULL` or a pointer to a structure extending this structure.

- `pStdSPS` is `NULL` or a pointer to an instance of the `StdVideoH264SequenceParameterSet` structure describing the active H.264 SPS.

- `pStdPPS` is `NULL` or a pointer to an instance of the `StdVideoH264PictureParameterSet` structure describing the active H.264 PPS.

## Description

If `pStdSPS` or `pStdPPS` is not `NULL`, the issued video decode operations will use the parameter sets specified by them, respectively, instead of the corresponding parameter sets being sourced from the bound video session parameters object.

Valid Usage (Implicit)

- VUID-VkVideoDecodeH264InlineSessionParametersInfoKHR-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_VIDEO_DECODE_H264_INLINE_SESSION_PARAMETERS_INFO_KHR`

- VUID-VkVideoDecodeH264InlineSessionParametersInfoKHR-pStdSPS-parameter
  If `pStdSPS` is not `NULL`, `pStdSPS` must be a valid pointer to a valid `StdVideoH264SequenceParameterSet` value

- VUID-VkVideoDecodeH264InlineSessionParametersInfoKHR-pStdPPS-parameter
  If `pStdPPS` is not `NULL`, `pStdPPS` must be a valid pointer to a valid `StdVideoH264PictureParameterSet` value
