VkVideoEncodeH264CapabilityFlagBitsEXT - Video encode H.264 capability flags Description

• VIDEO_ENCODE_H264_CAPABILITY_HRD_COMPLIANCE_BIT_EXT indicates if the implementation guarantees generating a HRD compliant bitstream if nal_hrd_parameters_present_flag or vcl_hrd_parameters_present_flag are enabled in StdVideoH264SpsVuiFlags.
• VIDEO_ENCODE_H264_CAPABILITY_PREDICTION_WEIGHT_TABLE_GENERATED_BIT_EXT indicates that when weighted_pred_flag is enabled or STD_VIDEO_H264_WEIGHTED_BIPRED_IDC_EXPLICIT from StdVideoH264WeightedBipredIdc is used, the implementation is able to internally decide syntax for pred_weight_table.
• VIDEO_ENCODE_H264_CAPABILITY_ROW_UNALIGNED_SLICE_BIT_EXT indicates 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).

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.
• VIDEO_ENCODE_H264_CAPABILITY_B_FRAME_IN_L0_LIST_BIT_EXT indicates support for using a B frame as L0 reference.
• VIDEO_ENCODE_H264_CAPABILITY_B_FRAME_IN_L1_LIST_BIT_EXT indicates support for using a B frame as L1 reference.
