D3DKMDT_VIDPN_PRESENT_PATH_IMPORTANCE enumeration

The D3DKMDT_VIDPN_PRESENT_PATH_IMPORTANCE enumeration indicates the importance of a video present path.

Syntax


typedef enum _D3DKMDT_VIDPN_PRESENT_PATH_IMPORTANCE { 
  D3DKMDT_VPPI_UNINITIALIZED  = 0,
  D3DKMDT_VPPI_PRIMARY        = 1,
  D3DKMDT_VPPI_SECONDARY      = 2,
  D3DKMDT_VPPI_TERTIARY       = 3,
  D3DKMDT_VPPI_QUATERNARY     = 4,
  D3DKMDT_VPPI_QUINARY        = 5,
  D3DKMDT_VPPI_SENARY         = 6,
  D3DKMDT_VPPI_SEPTENARY      = 7,
  D3DKMDT_VPPI_OCTONARY       = 8,
  D3DKMDT_VPPI_NONARY         = 9,
  D3DKMDT_VPPI_DENARY         = 10
} D3DKMDT_VIDPN_PRESENT_PATH_IMPORTANCE;

Constants

D3DKMDT_VPPI_UNINITIALIZED

Indicates that a variable of type D3DKMDT_VIDPN_PRESENT_PATH_IMPORTANCE has not yet been assigned a meaningful value.

D3DKMDT_VPPI_PRIMARY

Indicates importance level 1.

D3DKMDT_VPPI_SECONDARY

Indicates importance level 2.

D3DKMDT_VPPI_TERTIARY

Indicates importance level 3.

D3DKMDT_VPPI_QUATERNARY

Indicates importance level 4.

D3DKMDT_VPPI_QUINARY

Indicates importance level 5.

D3DKMDT_VPPI_SENARY

Indicates importance level 6.

D3DKMDT_VPPI_SEPTENARY

Indicates importance level 7.

D3DKMDT_VPPI_OCTONARY

Indicates importance level 8.

D3DKMDT_VPPI_NONARY

Indicates importance level 9.

D3DKMDT_VPPI_DENARY

Indicates importance level 10.

Remarks

As the numeric value of a D3DKMDT_VIDPN_PRESENT_PATH_IMPORTANCE value increases, the importance decreases. For example, level 3 is less important than level 2.

A variable of type D3DKMDT_VIDPN_PRESENT_PATH_IMPORTANCE can have any integer value in the range 0 through 255, but only the values 0 through 10 have names.

It is useful to rank the video present paths in a video present network (VidPN) according to importance. For example, a path that represents the primary view can be assigned a higher importance than other paths so that it gets the best source and target mode sets.

The ImportanceOrdinal member of the D3DKMDT_VIDPN_PRESENT_PATH structure is a D3DKMDT_VIDPN_PRESENT_PATH_IMPORTANCE value. Path importance ordinal numbers are unique within a given VidPN topology.
