Constants

D3D12DDI_VIDEO_ENCODER_AV1_FRAME_SUBREGION_LAYOUT_CONFIG_VALIDATION_0095_FLAG_NONE Value: 0x0 No flags are specified.
D3D12DDI_VIDEO_ENCODER_AV1_FRAME_SUBREGION_LAYOUT_CONFIG_VALIDATION_0095_FLAG_NOT_SPECIFIED Value: 0x1 When this flag is set, indicates that the requested tiles configuration is not supported due to a reason not specified by any of the other flag categories.
D3D12DDI_VIDEO_ENCODER_AV1_FRAME_SUBREGION_LAYOUT_CONFIG_VALIDATION_0095_FLAG_CODEC_CONSTRAINT Value: 0x2 When this flag is set, indicates that the requested tiles configuration is not supported due to codec constraints. An example on this for AV1 would be D3D12DDI_FEATURE_DATA_VIDEO_ENCODER_FRAME_SUBREGION_LAYOUT_CONFIG_0095.Level.
D3D12DDI_VIDEO_ENCODER_AV1_FRAME_SUBREGION_LAYOUT_CONFIG_VALIDATION_0095_FLAG_HARDWARE_CONSTRAINT Value: 0x4 When this flag is set, indicates that the requested tiles configuration is not supported due to hardware constraints.
D3D12DDI_VIDEO_ENCODER_AV1_FRAME_SUBREGION_LAYOUT_CONFIG_VALIDATION_0095_FLAG_ROWS_COUNT Value: 0x8 When this flag is set, indicates that the number of tile rows requested is not supported.
D3D12DDI_VIDEO_ENCODER_AV1_FRAME_SUBREGION_LAYOUT_CONFIG_VALIDATION_0095_FLAG_COLS_COUNT Value: 0x10 When this flag is set, indicates that the number of tile columns requested is not supported.
D3D12DDI_VIDEO_ENCODER_AV1_FRAME_SUBREGION_LAYOUT_CONFIG_VALIDATION_0095_FLAG_WIDTH Value: 0x20 When this flag is set, indicates that one or more tiles widths in the requested configuration is not supported.
D3D12DDI_VIDEO_ENCODER_AV1_FRAME_SUBREGION_LAYOUT_CONFIG_VALIDATION_0095_FLAG_AREA Value: 0x40 When this flag is set, indicates that one or more tiles areas in the requested configuration is not supported.
D3D12DDI_VIDEO_ENCODER_AV1_FRAME_SUBREGION_LAYOUT_CONFIG_VALIDATION_0095_FLAG_TOTAL_TILES Value: 0x80 When this flag is set, indicates that the total number of tiles in the requested partition exceeds the total supported tiles count. Please see D3D12DDI_VIDEO_ENCODER_RESOLUTION_SUPPORT_LIMITS_0080_2.MaxSubregionsNumber.
