## C Specification

Possible values of VkVideoEncodeH265RateControlInfoEXT::`rateControlStructure`, specifying a video stream reference structure as a hint for the rate control implementation, are:

    // Provided by VK_EXT_video_encode_h265
    typedef enum VkVideoEncodeH265RateControlStructureEXT {
        VK_VIDEO_ENCODE_H265_RATE_CONTROL_STRUCTURE_UNKNOWN_EXT = 0,
        VK_VIDEO_ENCODE_H265_RATE_CONTROL_STRUCTURE_FLAT_EXT = 1,
        VK_VIDEO_ENCODE_H265_RATE_CONTROL_STRUCTURE_DYADIC_EXT = 2,
    } VkVideoEncodeH265RateControlStructureEXT;

## Description

- `VK_VIDEO_ENCODE_H265_RATE_CONTROL_STRUCTURE_UNKNOWN_EXT` specifies a reference structure unknown at the time of stream rate control configuration.

- `VK_VIDEO_ENCODE_H265_RATE_CONTROL_STRUCTURE_FLAT_EXT` specifies a flat reference structure.

- `VK_VIDEO_ENCODE_H265_RATE_CONTROL_STRUCTURE_DYADIC_EXT` specifies a dyadic reference structure.
