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.
