ILMVPredator Interface

Data Types

REFERENCE_FRAME

Summary

Specifies the reference frame.

Syntax

enum REFERENCE_FRAME 
{ 
   REF_USEBUFFER, 
   REF_USENEXTFRAME, 
   REF_USECOLOR, 
}; 

Members

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.

HorizontalDirectionConstants

Summary

Specifies the horizontal displacement direction.

Syntax

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

Members

HORIZONTAL_DIRECTION_LEFT

The pixels displace from right to left.

HORIZONTAL_DIRECTION_RIGHT

The pixels displace from left to right.

VerticalDirectionConstants

Summary

Specifies the vertical displacement direction.

Syntax

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

Members

VERTICAL_DIRECTION_UP

The pixels displace from down to up.

VERTICAL_DIRECTION_DOWN

The pixels displace from up to down.

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.
VerticalDirectionConstants VerticalDirection Gets or sets the vertical displacement direction.

Methods

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

Description

Sets the reference frame of the movie.

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.

Returns

Return Description
S_OK Successful.
< 0 An error occurred.
