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.

Parameters

Description

SetReferenceFrame

byte* pBuffer, [in] long lRGBColor, [in] REFERENCE_FRAME opt

Sets the reference frame of the movie.

 

 

Parameters

Description

 

 

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.
