C Specification

The rateControlStructure in VkVideoEncodeH264RateControlInfoEXT specifies one of the following video stream reference structures as a hint for the rate control implementation:

// Provided by VK_EXT_video_encode_h264
typedef enum VkVideoEncodeH264RateControlStructureEXT {
    VK_VIDEO_ENCODE_H264_RATE_CONTROL_STRUCTURE_UNKNOWN_EXT = 0,
    VK_VIDEO_ENCODE_H264_RATE_CONTROL_STRUCTURE_FLAT_EXT = 1,
    VK_VIDEO_ENCODE_H264_RATE_CONTROL_STRUCTURE_DYADIC_EXT = 2,
} VkVideoEncodeH264RateControlStructureEXT;

Description

  • VK_VIDEO_ENCODE_H264_RATE_CONTROL_STRUCTURE_UNKNOWN_EXT specifies a reference structure unknown at the time of stream rate control configuration.

  • VK_VIDEO_ENCODE_H264_RATE_CONTROL_STRUCTURE_FLAT_EXT specifies a flat reference structure.

  • VK_VIDEO_ENCODE_H264_RATE_CONTROL_STRUCTURE_DYADIC_EXT specifies a dyadic reference structure.
