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.
