The DXVAHDDDI_DEVICE_USAGE enumeration contains values that identify how the decode device plays video.

Syntax


typedef enum _DXVAHDDDI_DEVICE_USAGE { 
  DXVAHDDDI_DEVICE_USAGE_PLAYBACK_NORMAL  = 0,
  DXVAHDDDI_DEVICE_USAGE_OPTIMAL_SPEED    = 1,
  DXVAHDDDI_DEVICE_USAGE_OPTIMAL_QUALITY  = 2
} DXVAHDDDI_DEVICE_USAGE;

A value that specifies that the device plays video at normal speed.

DXVAHDDDI_DEVICE_USAGE_OPTIMAL_SPEED

A value that specifies that the device plays video at optimal speed.

DXVAHDDDI_DEVICE_USAGE_OPTIMAL_QUALITY

A value that specifies that the device plays video at optimal quality.

Remarks

A DXVAHDDDI_DEVICE_USAGE-typed value is specified in the Usage member of a DXVAHDDDI_DEVICE_DESC structure to help describe a decode device.
