ILMVPredator Interface

Data Types:

REFERENCE_FRAME

enum REFERENCE_FRAME 
{ 
   REF_USEBUFFER, 
   REF_USENEXTFRAME, 
   REF_USECOLOR, 
};

HorizontalDirectionConstants

typedef [v1_enum] enum HorizontalDirectionConstants 
{ 
   HORIZONTAL_DIRECTION_LEFT = 0, 
   HORIZONTAL_DIRECTION_RIGHT = 1 
} HorizontalDirectionConstants;

VerticalDirectionConstants

typedef [v1_enum] enum VerticalDirectionConstants 
{ 
   VERTICAL_DIRECTION_UP = 0, 
   VERTICAL_DIRECTION_DOWN = 1 
} VerticalDirectionConstants;

Interface Properties:

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. If this is VARIANT_TRUE, the first frame in every play session will be set as the reference frame (Usually the first frame in a movie).
long	Threshold	Value used to control an object's detection level. A lower threshold provides stronger object detection. Range: 1 to 100.
long	HorizontalPixels	Gets or sets the number of horizontal displacement pixels. The value ranges from 0 to video width.
long	VerticalPixels	Gets or sets the number of vertical displacement pixels. The value ranges from 0 to video height.
HorizontalDirectionConstants	HorizontalDirection	Gets or sets the horizontal displacement direction. Possible value can be on of the following: HORIZONTAL_DIRECTION_LEFT: The pixels displace from right to left. HORIZONTAL_DIRECTION_RIGHT: The pixels displace from left to right.
VerticalDirectionConstants	VerticalDirection	Gets or sets the vertical displacement direction. Possible value can be on of the following: VERTICAL_DIRECTION_UP: The pixels displace from down to up. VERTICAL_DIRECTION_DOWN: The pixels displace from up to down.

Interface Methods:

HRESULT SetReferenceFrame(byte *pBuffer, long lRGBColor, REFERENCE_FRAME opt);

Parameters

pBuffer	Buffer contains the reference frame. This buffer should have the same dimensions (width and height), and the same bits per pixel as the movie.
lRGBColor	Pixel color (RGB 24-bit). The reference frame will be set as a solid frame with the color specified in this parameter.
opt	Flag that controls the reference frame. Possible values are:
	Value	Meaning
	REF_USEBUFFER	only the pBuffer member is used.
	REF_USENEXTFRAME	the next frame in the movie is taken as the reference frame.
	REF_USECOLOR	the lRGBColor parameter is used.

Description

Sets the reference frame of the movie.

Returns

S_OK if successful, < 0 if an error occurred.
