C Specification
Bits which can be set in
VkVideoEncodeAV1RateControlInfoKHR::flags, specifying AV1 rate
control flags, are:
// Provided by VK_KHR_video_encode_av1
typedef enum VkVideoEncodeAV1RateControlFlagBitsKHR {
VK_VIDEO_ENCODE_AV1_RATE_CONTROL_REGULAR_GOP_BIT_KHR = 0x00000001,
VK_VIDEO_ENCODE_AV1_RATE_CONTROL_TEMPORAL_LAYER_PATTERN_DYADIC_BIT_KHR = 0x00000002,
VK_VIDEO_ENCODE_AV1_RATE_CONTROL_REFERENCE_PATTERN_FLAT_BIT_KHR = 0x00000004,
VK_VIDEO_ENCODE_AV1_RATE_CONTROL_REFERENCE_PATTERN_DYADIC_BIT_KHR = 0x00000008,
} VkVideoEncodeAV1RateControlFlagBitsKHR;Description
-
VK_VIDEO_ENCODE_AV1_RATE_CONTROL_REGULAR_GOP_BIT_KHR specifies that the application intends to use a regular GOP structure according to the parameters specified in the
gopFrameCountandkeyFramePeriodmembers of the VkVideoEncodeAV1RateControlInfoKHR structure. -
VK_VIDEO_ENCODE_AV1_RATE_CONTROL_TEMPORAL_LAYER_PATTERN_DYADIC_BIT_KHR specifies that the application intends to follow a dyadic temporal layer pattern.
-
VK_VIDEO_ENCODE_AV1_RATE_CONTROL_REFERENCE_PATTERN_FLAT_BIT_KHR specifies that the application intends to follow a flat reference pattern in the GOP.
-
VK_VIDEO_ENCODE_AV1_RATE_CONTROL_REFERENCE_PATTERN_DYADIC_BIT_KHR specifies that the application intends to follow a dyadic reference pattern in the GOP.
