filterType
A PreferredFilter enumeration value specifying the desired filter type
A string of a filter's display name.
This method can be used to determine whether a preferred filter has been set by SetPreferredFilter. It will return NULL (if no preferred filter has been set) or a display name indicating the preferred filter. A display name uniquely identifies the filter. Display names have the following format:
@device:sw:GUID\GUID
For example, the display name for the LEAD MPEG2 Transport Demultiplexer is: @device:sw:{083863F1-70DE-11D0-BD40-00A0C911CE86}\{E2B7DF1A-38C5-11D5-91F6-00104BDB8FF9}
A list of display names for common filters can be found in Constants.PreferredFilters.
Please see SetPreferredFilter for more information on filter display names.
