ILMVGhost Interface

Data Types

This filter has no specific data types, but offers the following enumeration for use with its programming interface:

Specifies the reference frame.

enum REFERENCE_FRAME 
{ 
   REF_USEBUFFER, 
   REF_USENEXTFRAME, 
   REF_USECOLOR, 
};

Only the pBuffer member is used.

The next frame in the movie is taken as the reference frame.

The lRGBColor parameter is used.

Type	Name	Description
VARIANT_BOOL	Enabled	Enables or disables the effect. If set to VARIANT_FALSE, the filter will pass the video samples intact.
VARIANT_BOOL	FirstFrameIsReference	Enables or disables setting the first frame in every play session as the reference frame. Possible values are:
		• VARIANT_TRUE - the first frame in every play session will be set as the reference frame (Usually the first frame in a movie).
		• VARIANT_FALSE - then the reference frame should be set manually after a number of frames. Setting this property after the stream starts will have no effect.
long	Threshold	Value used to control an object's detection level. A lower threshold provides stronger object detection. Range : 1 to 100.
