If not supported, the implementation decides the number of macroblocks in each slice based on VkVideoEncodeH264VclFrameInfoEXT::naluSliceEntryCount.
• VIDEO_ENCODE_H264_CAPABILITY_ROW_UNALIGNED_SLICE_BIT_EXT reports that each slice in a frame with multiple slices may begin or finish at any offset in a macroblock row. If not supported, all slices in the frame must begin at the start of a macroblock row (and hence each slice must finish at the end of a macroblock row).
• VIDEO_ENCODE_H264_CAPABILITY_DIFFERENT_SLICE_TYPE_BIT_EXT reports that when VIDEO_ENCODE_H264_CAPABILITY_MULTIPLE_SLICE_PER_FRAME_BIT_EXT is supported and a frame is encoded with multiple slices, the implementation allows encoding each slice with a different StdVideoEncodeH264SliceHeader::slice_type. If not supported, all slices of the frame must be encoded with the same slice_type which corresponds to the picture type of the frame. For example, all slices of a P-frame would be encoded as P-slices.

VK_VIDEO_ENCODE_H264_INPUT_MODE_FRAME_BIT_EXT, VK_VIDEO_ENCODE_H264_INPUT_MODE_SLICE_BIT_EXT, VK_VIDEO_ENCODE_H264_INPUT_MODE_NON_VCL_BIT_EXT

VkVideoEncodeH264InputModeFlagBitsEXT - Video encode H.264 input modes

Description

• VIDEO_ENCODE_H264_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_H264_INPUT_MODE_NON_VCL_BIT_EXT is not supported.
• VIDEO_ENCODE_H264_INPUT_MODE_SLICE_BIT_EXT indicates that a single command buffer must at least encode a single slice. Any non-VCL NALUs must be encoded using the same command buffer as the first slice of the frame if VIDEO_ENCODE_H264_INPUT_MODE_NON_VCL_BIT_EXT is not supported.
• VIDEO_ENCODE_H264_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_H264_INPUT_MODE_FRAME_BIT_EXT or VIDEO_ENCODE_H264_INPUT_MODE_SLICE_BIT_EXT.

If VIDEO_ENCODE_H264_INPUT_MODE_SLICE_BIT_EXT is not supported, the following two additional restrictions apply for frames encoded with multiple slices. First, all frame slices must have the same pRefList0ModOperations and the same pRefList1ModOperations. Second, the order in which slices appear in VkVideoEncodeH264VclFrameInfoEXT::pNaluSliceEntries or in the command buffer must match the placement order of the slices in the frame.

VK_VIDEO_ENCODE_H264_OUTPUT_MODE_FRAME_BIT_EXT, VK_VIDEO_ENCODE_H264_OUTPUT_MODE_SLICE_BIT_EXT, VK_VIDEO_ENCODE_H264_OUTPUT_MODE_NON_VCL_BIT_EXT

VkVideoEncodeH264OutputModeFlagBitsEXT - Video encode H.264 output modes

Description

• VIDEO_ENCODE_H264_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_H264_OUTPUT_MODE_NON_VCL_BIT_EXT is not supported.
• VIDEO_ENCODE_H264_OUTPUT_MODE_SLICE_BIT_EXT indicates that each begin/end pair must encode at least one slice. Any non-VCL NALUs must be encoded within the same begin/end pair as the first slice of the frame if VIDEO_ENCODE_H264_OUTPUT_MODE_NON_VCL_BIT_EXT is not supported.
• VIDEO_ENCODE_H264_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_H264_OUTPUT_MODE_FRAME_BIT_EXT or VIDEO_ENCODE_H264_OUTPUT_MODE_SLICE_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.264 standard).

The supported input modes must be coarser or equal to the supported output modes. For example, it is illegal to report slice 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
• Input: Frame, Output: Slice and Non-VCL
• Input: Slice, Output: Slice
• Input: Slice, Output: Slice and Non-VCL
• Input: Frame and Non-VCL, Output: Frame and Non-VCL
• Input: Frame and Non-VCL, Output: Slice and Non-VCL
• Input: Slice and Non-VCL, Output: Slice and Non-VCL

Description

• VIDEO_ENCODE_H264_CREATE_DEFAULT_EXT is 0, and specifies no additional creation flags.
• VIDEO_ENCODE_H264_CREATE_RESERVED_0_BIT_EXT The current version of the specification has reserved this value for future use.
