VkVideoEncodeIntraRefreshModeFlagBitsKHR(3)
C Specification
The intra refresh modes are defined with the following enums:
// Provided by VK_KHR_video_encode_intra_refresh
typedef enum VkVideoEncodeIntraRefreshModeFlagBitsKHR {
VK_VIDEO_ENCODE_INTRA_REFRESH_MODE_NONE_KHR = 0,
VK_VIDEO_ENCODE_INTRA_REFRESH_MODE_PER_PICTURE_PARTITION_BIT_KHR = 0x00000001,
VK_VIDEO_ENCODE_INTRA_REFRESH_MODE_BLOCK_BASED_BIT_KHR = 0x00000002,
VK_VIDEO_ENCODE_INTRA_REFRESH_MODE_BLOCK_ROW_BASED_BIT_KHR = 0x00000004,
VK_VIDEO_ENCODE_INTRA_REFRESH_MODE_BLOCK_COLUMN_BASED_BIT_KHR = 0x00000008,
} VkVideoEncodeIntraRefreshModeFlagBitsKHR;Description
-
VK_VIDEO_ENCODE_INTRA_REFRESH_MODE_NONE_KHR specifies that intra refresh must not be used.
-
VK_VIDEO_ENCODE_INTRA_REFRESH_MODE_PER_PICTURE_PARTITION_BIT_KHR specifies the use of per picture partition intra refresh. In this mode each intra refresh region i corresponds to the encoded picture partition i.
-
VK_VIDEO_ENCODE_INTRA_REFRESH_MODE_BLOCK_BASED_BIT_KHR specifies the use of any block-based intra refresh. In this mode each intra refresh region encompasses a set of coding blocks, independent of encoded picture partitions but without any additional guarantees on the granularity at which the picture is split into intra refresh regions. When using this mode, the set of coding blocks comprising the intra refresh regions and the direction of intra refresh are implementation-defined.
-
VK_VIDEO_ENCODE_INTRA_REFRESH_MODE_BLOCK_ROW_BASED_BIT_KHR specifies the use of block-row-based intra refresh. This mode is a block-based intra refresh mode where each intra refresh region encompasses a set of coding block rows.
-
VK_VIDEO_ENCODE_INTRA_REFRESH_MODE_BLOCK_COLUMN_BASED_BIT_KHR specifies the use of block-column-based intra refresh. This mode is a block-based intra refresh mode where each intra refresh region encompasses a set of coding block columns.
