Video decode statistics for a query.

Syntax

typedef struct D3D12DDI_QUERY_DATA_VIDEO_DECODE_STATISTICS_0022 {
  UINT64        Status;
  UINT64        NumMacroblocksAffected;
  DXGI_RATIONAL FrameRate;
  UINT          BitRate;
} D3D12DDI_QUERY_DATA_VIDEO_DECODE_STATISTICS_0022;

Members

Status

Specifies the status of an operation as a D3D12DDI_VIDEO_DECODE_STATUS value. This value is extended to 64bits to accommodate predication.

NumMacroblocksAffected

The number of blocks affected. If the Status value is not 0, this member contains an estimate from the accelerator of the number of super-blocks in the decoded frame that were adversely affected by the reported problem. If the accelerator does not provide an estimate, the value is 0xFFFFFFFFFFFFFFFF.

FrameRate

The frame rate.

BitRate

When the Status value returned is D3D12DDI_VIDEO_DECODE_STATUS_RATE_EXCEEDED, this member reports the required bit rate. This value may be used to recreate the decode stream and try again. The updated value is relative to the frame rate with which the stream was created. A value of zero (0) is valid to indicate that the worst case bit rate should be assumed. For all other Status values, BitRate is not used and is set to zero.
