D3D12_FEATURE_DATA_VIDEO_ENCODER_OUTPUT_RESOLUTION structure (d3d12video.h)

  • Article

Provides data for calls to ID3D12VideoDevice::CheckFeatureSupport when the feature specified is D3D12_FEATURE_VIDEO_ENCODER_OUTPUT_RESOLUTION. Retrieves the list of supported resolutions for the specified codec.

Syntax

typedef struct D3D12_FEATURE_DATA_VIDEO_ENCODER_OUTPUT_RESOLUTION {
  UINT                                              NodeIndex;

  BOOL                                              IsSupported;
  D3D12_VIDEO_ENCODER_PICTURE_RESOLUTION_DESC       MinResolutionSupported;
  D3D12_VIDEO_ENCODER_PICTURE_RESOLUTION_DESC       MaxResolutionSupported;
  UINT                                              ResolutionWidthMultipleRequirement;
  UINT                                              ResolutionHeightMultipleRequirement;
  D3D12_VIDEO_ENCODER_PICTURE_RESOLUTION_RATIO_DESC *pResolutionRatios;
} D3D12_FEATURE_DATA_VIDEO_ENCODER_OUTPUT_RESOLUTION;

Members

NodeIndex

For single GPU operation, set this to zero. If there are multiple GPU nodes, set a bit to identify the node (the device's physical adapter) to which the command queue applies. Each bit in the mask corresponds to a single node. Only 1 bit may be set.

Codec

A member of the D3D12_VIDEO_ENCODER_CODEC enumeration specifying the codec for which the supported resolutions are being queried.

ResolutionRatiosCount

The number of resolution ratios to retrieve. This number must match the number in the D3D12_FEATURE_DATA_VIDEO_ENCODER_OUTPUT_RESOLUTION_RATIOS_COUNT.ResolutionRatiosCount field returned from a call to ID3D12VideoDevice::CheckFeatureSupport with D3D12_FEATURE_VIDEO_ENCODER_OUTPUT_RESOLUTION_RATIOS_COUNT specified as the feature.

IsSupported

Receives a boolean indicating if the query inputs are supported.

MinResolutionSupported

Receives the minimum resolution supported for the specified codec.

MaxResolutionSupported

Receives the maximum resolution supported for the specified codec.

ResolutionWidthMultipleRequirement

A UINT specifying a number by which the resolution width component must be divisible.

ResolutionHeightMultipleRequirement

A UINT specifying a number by which the resolution height component must be divisible.

pResolutionRatios

Receives a list of D3D12_VIDEO_ENCODER_PICTURE_RESOLUTION_RATIO_DESC representing the supported resolution ratios for the specified codec as irreducible fractions. The caller must allocate the memory for this array based on the ResolutionRatiosCount field, and assign it to the query struct the call to ID3D12VideoDevice::CheckFeatureSupport.
