GetMerit Method

Java
C++

public int GetMerit( 
   string Name
)

'Declaration

Public Function GetMerit( _
   ByVal Name As String _
) As Integer

'Usage

Dim instance As FilterEnum
Dim Name As String
Dim value As Integer
 
value = instance.GetMerit(Name)

public:
int GetMerit( 
   String^ Name
)

Parameters

Name: String used as the Display Name or Friendly Name of the filter. It is best to use the "Display Name" since it is unique and no two filters can have the same Display Name. On the contrary, two or more filters can have the same Friendly Name. If two or more filters have the same Friendly Name, this function works on the first filter it internally enumerates with the specified friendly name.

Return Value

An integer value that represents the merit of a DirectShow filter.

For more information, refer to the Microsoft documentation for DirectShow Merits http://msdn.microsoft.com/en-us/library/dd390674(VS.85).aspx http://msdn.microsoft.com/en-us/library/aa920889.aspx http://msmvps.com/blogs/chrisl/articles/40395.aspx A Display Name uniquely identifies a DirectShow filter (or any filter). Display names for software filters have the following format: @device:sw:GUID\\GUID, example: Microsoft's “MPEG-2 Splitter” display name is: @device:sw:{083863F1-70DE-11D0-BD40-00A0C911CE86}\\{3AE86B20-7BE8-11D1-ABE6-00A0C905F375}. A Friendly Name is not unique and one or more filters can have the same name. However, it is ideal for presenting a descriptive name in user interfaces. For example, the Friendly Name for Microsoft's MPEG-2 Splitter is "MPEG-2 Splitter"
