C Specification
Bits which may be set in
VkVideoEncodeAV1CapabilitiesKHR::stdSyntaxFlags, indicating the
capabilities related to the AV1 syntax elements, are:
// Provided by VK_KHR_video_encode_av1
typedef enum VkVideoEncodeAV1StdFlagBitsKHR {
VK_VIDEO_ENCODE_AV1_STD_UNIFORM_TILE_SPACING_FLAG_SET_BIT_KHR = 0x00000001,
VK_VIDEO_ENCODE_AV1_STD_SKIP_MODE_PRESENT_UNSET_BIT_KHR = 0x00000002,
VK_VIDEO_ENCODE_AV1_STD_PRIMARY_REF_FRAME_BIT_KHR = 0x00000004,
VK_VIDEO_ENCODE_AV1_STD_DELTA_Q_BIT_KHR = 0x00000008,
} VkVideoEncodeAV1StdFlagBitsKHR;Description
-
VK_VIDEO_ENCODE_AV1_STD_UNIFORM_TILE_SPACING_FLAG_SET_BIT_KHR specifies whether the implementation supports using the application-provided value for
StdVideoAV1TileInfoFlags::uniform_tile_spacing_flagin the AV1 tile parameters when that value is1, regardless of the coded extent of the encode input picture and the number of tile columns and rows requested in theTileColsandTileRowsmembers ofStdVideoAV1TileInfo. -
VK_VIDEO_ENCODE_AV1_STD_SKIP_MODE_PRESENT_UNSET_BIT_KHR specifies whether the implementation supports using the application-provided value for
StdVideoEncodeAV1PictureInfoFlags::skip_mode_presentwhen that value is0. -
VK_VIDEO_ENCODE_AV1_STD_PRIMARY_REF_FRAME_BIT_KHR specifies whether the implementation supports using the application-provided value for
StdVideoEncodeAV1PictureInfo::primary_ref_frame. -
VK_VIDEO_ENCODE_AV1_STD_DELTA_Q_BIT_KHR specifies whether the implementation supports using the application-provided values for the
DeltaQYDc,DeltaQUDc,DeltaQUAc,DeltaQVDc, andDeltaQVAcmembers ofStdVideoAV1Quantization.
These capability flags provide information to the application about specific AV1 syntax element values that the implementation supports without having to override them and do not otherwise restrict the values that the application can specify for any of the mentioned AV1 syntax elements.
