C Specification
Bits which can be set in
VkVideoEncodeH265RateControlInfoKHR::flags, specifying H.265
rate control flags, are:
// Provided by VK_KHR_video_encode_h265

} VkVideoEncodeH265RateControlFlagBitsKHR;Description
-
VK_VIDEO_ENCODE_H265_RATE_CONTROL_ATTEMPT_HRD_COMPLIANCE_BIT_KHR specifies that rate control should attempt to produce an HRD compliant bitstream, as defined in annex C of the ITU-T H.265 Specification.
-
VK_VIDEO_ENCODE_H265_RATE_CONTROL_REGULAR_GOP_BIT_KHR specifies that the application intends to use a regular GOP structure according to the parameters specified in the
gopFrameCount,idrPeriod, andconsecutiveBFrameCountmembers of the VkVideoEncodeH265RateControlInfoKHR structure. -
VK_VIDEO_ENCODE_H265_RATE_CONTROL_REFERENCE_PATTERN_FLAT_BIT_KHR specifies that the application intends to follow a flat reference pattern in the GOP.
-
VK_VIDEO_ENCODE_H265_RATE_CONTROL_REFERENCE_PATTERN_DYADIC_BIT_KHR specifies that the application intends to follow a dyadic reference pattern in the GOP.
-
VK_VIDEO_ENCODE_H265_RATE_CONTROL_TEMPORAL_SUB_LAYER_PATTERN_DYADIC_BIT_KHR specifies that the application intends to follow a dyadic temporal sub-layer pattern.
