## Name

VkVideoEncodeH265VclFrameInfoEXT - Structure specifies H.265 encode frame parameters

Loading… please wait.

## C Specification

The VkVideoEncodeH265VclFrameInfoEXT structure representing a frame encode operation is defined as:

    // Provided by VK_EXT_video_encode_h265
    typedef struct VkVideoEncodeH265VclFrameInfoEXT {
        VkStructureType                                sType;
        const void*                                    pNext;
        const VkVideoEncodeH265ReferenceListsEXT*      pReferenceFinalLists;
        uint32_t                                       naluSliceSegmentEntryCount;
        const VkVideoEncodeH265NaluSliceSegmentEXT*    pNaluSliceSegmentEntries;
        const StdVideoEncodeH265PictureInfo*           pCurrentPictureInfo;
    } VkVideoEncodeH265VclFrameInfoEXT;

## Members

- `sType` is the type of this structure.

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

- `pReferenceFinalLists` is `NULL` or a pointer to a VkVideoEncodeH265ReferenceListsEXT structure specifying the reference lists to be used for the current picture.

- `naluSliceSegmentEntryCount` is the number of slice segment NALUs in the frame.

- `pNaluSliceSegmentEntries` is a pointer to an array of VkVideoEncodeH265NaluSliceSegmentEXT structures specifying the division of the current picture into slice segments and the properties of these slice segments.

- `pCurrentPictureInfo` is a pointer to a `StdVideoEncodeH265PictureInfo` structure specifying the syntax and other codec-specific information from the H.265 specification, associated with this picture.

## Description

Valid Usage (Implicit)

- VUID-VkVideoEncodeH265VclFrameInfoEXT-sType-sType
  `sType` must be `VK_STRUCTURE_TYPE_VIDEO_ENCODE_H265_VCL_FRAME_INFO_EXT`

- VUID-VkVideoEncodeH265VclFrameInfoEXT-pReferenceFinalLists-parameter
  If `pReferenceFinalLists` is not `NULL`, `pReferenceFinalLists` must be a valid pointer to a valid VkVideoEncodeH265ReferenceListsEXT structure

- VUID-VkVideoEncodeH265VclFrameInfoEXT-pNaluSliceSegmentEntries-parameter
  `pNaluSliceSegmentEntries` must be a valid pointer to an array of `naluSliceSegmentEntryCount` valid VkVideoEncodeH265NaluSliceSegmentEXT structures

- VUID-VkVideoEncodeH265VclFrameInfoEXT-pCurrentPictureInfo-parameter
  `pCurrentPictureInfo` must be a valid pointer to a valid `StdVideoEncodeH265PictureInfo` value

- VUID-VkVideoEncodeH265VclFrameInfoEXT-naluSliceSegmentEntryCount-arraylength
  `naluSliceSegmentEntryCount` must be greater than `0`
