This filter has no specific data types, but offers the following enumeration for use with its programming interface:
Specifies the reference frame.
Only the pBuffer member is used.
The next frame in the movie is taken as the reference frame.
The lRGBColor parameter is used.
|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.|
Sets the reference frame of the movie.
Buffer contains the reference frame. This buffer should have the same dimensions (width and height), and the same bits per pixel as the movie.
Pixel color (RGB 24-bit). The reference frame will be set as a solid frame with the color specified in this parameter.
Flag that controls the reference frame.
