• VIDEO_ENCODE_H265_CAPABILITY_ROW_UNALIGNED_SLICE_SEGMENT_BIT_EXT reports that each slice segment in a frame with a single or multiple tiles per slice may begin or finish at any offset in a CTB row. If not supported, all slice segments in such a frame must begin at the start of a CTB row (and hence each slice segment must finish at the end of a CTB row). Also reports that each slice segment in a frame with multiple slices per tile may begin or finish at any offset within the enclosing tile’s CTB row. If not supported, slice segments in such a frame must begin at the start of the enclosing tile’s CTB row (and hence each slice segment must finish at the end of the enclosing tile’s CTB row).

If not supported, all slice segments of the frame must be encoded with the same slice_type which corresponds to the picture type of the frame. For example, all slice segments of a P-frame would be encoded as P-slices.

VK_VIDEO_ENCODE_H265_INPUT_MODE_FRAME_BIT_EXT, VK_VIDEO_ENCODE_H265_INPUT_MODE_SLICE_SEGMENT_BIT_EXT, VK_VIDEO_ENCODE_H265_INPUT_MODE_NON_VCL_BIT_EXT

VkVideoEncodeH265InputModeFlagBitsEXT - Video encode H.265 input modes

Description

• VIDEO_ENCODE_H265_INPUT_MODE_FRAME_BIT_EXT indicates that a single command buffer must at least encode an entire frame. Any non-VCL NALUs must be encoded using the same command buffer as the frame if VIDEO_ENCODE_H265_INPUT_MODE_NON_VCL_BIT_EXT is not supported.
• VIDEO_ENCODE_H265_INPUT_MODE_SLICE_SEGMENT_BIT_EXT indicates that a single command buffer must at least encode a single slice segment. Any non-VCL NALUs must be encoded using the same command buffer as the first slice segment of the frame if VIDEO_ENCODE_H265_INPUT_MODE_NON_VCL_BIT_EXT is not supported.
• VIDEO_ENCODE_H265_INPUT_MODE_NON_VCL_BIT_EXT indicates that a single command buffer may encode a non-VCL NALU by itself.

An implementation must support at least one of VIDEO_ENCODE_H265_INPUT_MODE_FRAME_BIT_EXT or VIDEO_ENCODE_H265_INPUT_MODE_SLICE_SEGMENT_BIT_EXT.

If VIDEO_ENCODE_H265_INPUT_MODE_SLICE_SEGMENT_BIT_EXT is not supported, the following two additional restrictions apply for frames encoded with multiple slice segments. First, all frame slice segments must have the same pReferenceFinalLists. Second, the order in which slice segments appear in VkVideoEncodeH265VclFrameInfoEXT::pNaluSliceSegmentEntries or in the command buffer must match the placement order of the slice segments in the frame.

VK_VIDEO_ENCODE_H265_OUTPUT_MODE_FRAME_BIT_EXT, VK_VIDEO_ENCODE_H265_OUTPUT_MODE_SLICE_SEGMENT_BIT_EXT, VK_VIDEO_ENCODE_H265_OUTPUT_MODE_NON_VCL_BIT_EXT

VkVideoEncodeH265OutputModeFlagBitsEXT - Video encode H.265 output modes

Description

• VIDEO_ENCODE_H265_OUTPUT_MODE_FRAME_BIT_EXT indicates that calls to generate all NALUs of a frame must be included within a single begin/end pair. Any non-VCL NALUs must be encoded within the same begin/end pair if VIDEO_ENCODE_H265_OUTPUT_MODE_NON_VCL_BIT_EXT is not supported.
• VIDEO_ENCODE_H265_OUTPUT_MODE_SLICE_SEGMENT_BIT_EXT indicates that each begin/end pair must encode at least one slice segment. Any non-VCL NALUs must be encoded within the same begin/end pair as the first slice segment of the frame if VIDEO_ENCODE_H265_OUTPUT_MODE_NON_VCL_BIT_EXT is not supported.
• VIDEO_ENCODE_H265_OUTPUT_MODE_NON_VCL_BIT_EXT indicates that each begin/end pair may encode only a non-VCL NALU by itself. An implementation must support at least one of VIDEO_ENCODE_H265_OUTPUT_MODE_FRAME_BIT_EXT or VIDEO_ENCODE_H265_OUTPUT_MODE_SLICE_SEGMENT_BIT_EXT.

A single begin/end pair must not encode more than a single frame.

The bitstreams of NALUs generated within a single begin/end pair are written continuously into the same bitstream buffer (any padding between the NALUs must be compliant to the H.265 standard).

The supported input modes must be coarser or equal to the supported output modes. For example, it is illegal to report slice segment input is supported but only frame output is supported.

An implementation must report one of the following combinations of input/output modes:

• Input: Frame, Output: Frame
• Input: Frame, Output: Frame and Non-VCL
• Input: Frame, Output: Slice Segment
• Input: Frame, Output: Slice Segment and Non-VCL
• Input: Slice Segment, Output: Slice Segment
• Input: Slice Segment, Output: Slice Segment and Non-VCL
• Input: Frame and Non-VCL, Output: Frame and Non-VCL
• Input: Frame and Non-VCL, Output: Slice Segment and Non-VCL
• Input: Slice Segment and Non-VCL, Output: Slice Segment and Non-VCL
