D3D12_VIDEO_ENCODER_PICTURE_CONTROL_FLAGS enumeration (d3d12video.h)

Specifies video encoder picture control flags.

Syntax

typedef enum D3D12_VIDEO_ENCODER_PICTURE_CONTROL_FLAGS {
  D3D12_VIDEO_ENCODER_PICTURE_CONTROL_FLAG_NONE,
  D3D12_VIDEO_ENCODER_PICTURE_CONTROL_FLAG_USED_AS_REFERENCE_PICTURE,
  D3D12_VIDEO_ENCODER_PICTURE_CONTROL_FLAG_ENABLE_QUANTIZATION_MATRIX_INPUT,
  D3D12_VIDEO_ENCODER_PICTURE_CONTROL_FLAG_ENABLE_DIRTY_REGIONS_INPUT,
  D3D12_VIDEO_ENCODER_PICTURE_CONTROL_FLAG_ENABLE_MOTION_VECTORS_INPUT
} ;

Constants

 
D3D12_VIDEO_ENCODER_PICTURE_CONTROL_FLAG_NONE
None.
D3D12_VIDEO_ENCODER_PICTURE_CONTROL_FLAG_USED_AS_REFERENCE_PICTURE
The associated frame will be used as a reference frame in future encode commands. Indicates that the reconstructed picture along with the bitstream should be output for the host to place it in future calls in the reconstructed pictures reference list.

Note that there might be limitations for some frame types to be marked as references. Check feature support before setting this value.
D3D12_VIDEO_ENCODER_PICTURE_CONTROL_FLAG_ENABLE_QUANTIZATION_MATRIX_INPUT
Enable GPU quantization map input via D3D12_VIDEO_ENCODER_QUANTIZATION_OPAQUE_MAP. Also requires D3D12_VIDEO_ENCODER_RATE_CONTROL_FLAG_ENABLE_DELTA_QP to be set.
D3D12_VIDEO_ENCODER_PICTURE_CONTROL_FLAG_ENABLE_DIRTY_REGIONS_INPUT
Enable dirty regions input via D3D12_VIDEO_ENCODER_DIRTY_REGIONS. The associated ID3D12VideoEncoderHeap must have been created with D3D12_VIDEO_ENCODER_HEAP_FLAG_ALLOW_DIRTY_REGIONS.
D3D12_VIDEO_ENCODER_PICTURE_CONTROL_FLAG_ENABLE_MOTION_VECTORS_INPUT
Enable motion vectors input via D3D12_VIDEO_ENCODER_FRAME_MOTION_VECTORS.

Remarks

Values from this enumeration are used by D3D12_VIDEO_ENCODER_PICTURE_CONTROL_DESC.

If this flag is not set, the D3D12_VIDEO_ENCODER_RECONSTRUCTED_PICTURE.pReconstructedPicture can be nullptr in the associated call to ID3D12VideoEncodeCommandList2::EncodeFrame.
