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 VkVideoEncodeH265RateControlStructureFlagBitsEXT {
    VK_VIDEO_ENCODE_H265_RATE_CONTROL_STRUCTURE_UNKNOWN_EXT = 0,
    VK_VIDEO_ENCODE_H265_RATE_CONTROL_STRUCTURE_FLAT_BIT_EXT = 0x00000001,
    VK_VIDEO_ENCODE_H265_RATE_CONTROL_STRUCTURE_DYADIC_BIT_EXT = 0x00000002,
} VkVideoEncodeH265RateControlStructureFlagBitsEXT;

Description

  • VK_VIDEO_ENCODE_H265_RATE_CONTROL_STRUCTURE_UNKNOWN_EXT is 0, and specifies a reference structure unknown at the time of stream rate control configuration.

  • VK_VIDEO_ENCODE_H265_RATE_CONTROL_STRUCTURE_FLAT_BIT_EXT specifies a flat reference structure.

  • VK_VIDEO_ENCODE_H265_RATE_CONTROL_STRUCTURE_DYADIC_BIT_EXT specifies a dyadic reference structure.
