C Specification
Bits which can be set in
VkVideoEncodeH264RateControlInfoEXT::flags, specifying H.264
rate control flags, are:
// Provided by VK_EXT_video_encode_h264
typedef enum VkVideoEncodeH264RateControlFlagBitsEXT {
VK_VIDEO_ENCODE_H264_RATE_CONTROL_ATTEMPT_HRD_COMPLIANCE_BIT_EXT = 0x00000001,
VK_VIDEO_ENCODE_H264_RATE_CONTROL_REGULAR_GOP_BIT_EXT = 0x00000002,
VK_VIDEO_ENCODE_H264_RATE_CONTROL_REFERENCE_PATTERN_FLAT_BIT_EXT = 0x00000004,
VK_VIDEO_ENCODE_H264_RATE_CONTROL_REFERENCE_PATTERN_DYADIC_BIT_EXT = 0x00000008,

} VkVideoEncodeH264RateControlFlagBitsEXT;
Description
-
VK_VIDEO_ENCODE_H264_RATE_CONTROL_ATTEMPT_HRD_COMPLIANCE_BIT_EXTspecifies that rate control should attempt to produce an HRD compliant bitstream. -
VK_VIDEO_ENCODE_H264_RATE_CONTROL_REGULAR_GOP_BIT_EXTspecifies that the application intends to use a regular GOP structure according to the parameters specified in thegopFrameCount,idrPeriod, andconsecutiveBFrameCountmembers of the VkVideoEncodeH264RateControlInfoEXT structure. -
VK_VIDEO_ENCODE_H264_RATE_CONTROL_REFERENCE_PATTERN_FLAT_BIT_EXTspecifies that the application intends to follow a flat reference pattern. -
VK_VIDEO_ENCODE_H264_RATE_CONTROL_REFERENCE_PATTERN_DYADIC_BIT_EXTspecifies that the application intends to follow a dyadic reference pattern. -
VK_VIDEO_ENCODE_H264_RATE_CONTROL_TEMPORAL_LAYER_PATTERN_DYADIC_BIT_EXTspecifies that the application intends to follow a dyadic temporal layer pattern.
