VkVideoEncodeAV1RateControlFlagBitsKHR

AV1 encode rate control bits

Bits which can be set in VkVideoEncodeAV1RateControlInfoKHR::flags, specifying AV1 rate control flags, are:

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;
  • 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 gopFrameCount and keyFramePeriod members 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.
