D3D11_FEATURE_DATA_VIDEO_DECODER_HISTOGRAM structure (d3d11_4.h)

Provides data for calls to ID3D11VideoDevice2::CheckFeatureSupport when the feature specified is D3D11_FEATURE_VIDEO_DECODER_HISTOGRAM. Retrieves the histogram capabilities for the specified decoder configuration.

Syntax

typedef struct D3D11_FEATURE_DATA_VIDEO_DECODER_HISTOGRAM {
  D3D11_VIDEO_DECODER_DESC                      DecoderDesc;
  D3D11_VIDEO_DECODER_HISTOGRAM_COMPONENT_FLAGS Components;
  UINT                                          BinCount;
  UINT                                          CounterBitDepth;
} D3D11_FEATURE_DATA_VIDEO_DECODER_HISTOGRAM;

Members

DecoderDesc

A D3D11_VIDEO_DECODER_DESC structure containing the decoder description for the decoder to be used with decode histogram.

Components

A bitwise OR combination of values from the D3D11_VIDEO_DECODER_HISTOGRAM_COMPONENT_FLAGS enumeration specifying the components of a DXGI_FORMAT for which histogram support will be queried.

BinCount

The number of per component bins supported. This value must be greater than or equal to 64 and must be a power of 2 (e.g. 64, 128, 256, 512...).

CounterBitDepth

The bit depth of the bin counter. The counter is always stored in a 32-bit value and therefore this value must specify 32 bits or less. The counter is stored in the lower bits of the 32-bit storage. The upper bits are set to zero. If the bin count exceeds this bit depth, the value is set to the maximum counter value. Valid values for CounterBitDepth are 16, 24, and 32.
