VkVideoEncodeH264NaluSliceInfoKHR

The VkVideoEncodeH264NaluSliceInfoKHR structure is defined as:

typedef struct VkVideoEncodeH264NaluSliceInfoKHR {
    VkStructureType sType;
    const void* pNext;
    int32_t constantQp;
    const StdVideoEncodeH264SliceHeader* pStdSliceHeader;
} VkVideoEncodeH264NaluSliceInfoKHR;

• sType is a VkStructureType value identifying this structure.
• pNext is NULL or a pointer to a structure extending this structure.
• constantQp is the QP to use for the slice if the current rate control mode configured for the video session is VK_VIDEO_ENCODE_RATE_CONTROL_MODE_DISABLED_BIT_KHR.
• pStdSliceHeader is a pointer to a StdVideoEncodeH264SliceHeader structure specifying H.264 slice header parameters for the slice.

Std Slice Header Parameters

The members of the StdVideoEncodeH264SliceHeader structure pointed to by pStdSliceHeader are interpreted as follows:

• flags.reserved and reserved1 are used only for padding purposes and are otherwise ignored;
• if pWeightTable is not NULL, then it is a pointer to a StdVideoEncodeH264WeightTable that is interpreted as follows:
  • flags.reserved is used only for padding purposes and is otherwise ignored;
  • all other members of StdVideoEncodeH264WeightTable are interpreted as defined in section 7.4.3.2 of the ITU-T H.264 Specification;
• all other members are interpreted as defined in section 7.4.3 of the ITU-T H.264 Specification.
