ILMVDeblock Interface

Data Types

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

DEBLOCKMETHOD

enum DEBLOCKMETHOD 
{ 
   DEBLOCK_TWOLINES = 0, 
   DEBLOCK_FOURLINES 
}; 

Describes the deblocking algorithms.

Properties

Type Name Description
VARIANT_BOOL Enabled Enable/Disable Deblocking. If set to VARIANT_FALSE, the filter will pass the video samples intact.
long DeblockAlgorithm One of the supported deblocking algorithms offered by this filter. For possible values, refer to DEBLOCKMETHOD.
long BlockWidth The expected block width in the passing stream. Possible values range from 2 to half of the passing sample width. If the filter input pin is not connected, the filter assumes dimensions of 1600 X 1600. For any value below the lower limit, a minimum value of 2 will be used. For any value beyond the upper limit, the maximum possible value will be used. Default value is 8.
long BlockHeight The expected block height in the passing stream. Possible values range from 2 to half of the passing sample height. If the filter input pin is not connected, the filter assumes dimensions of 1600 X 1600. For any value below the lower limit, a minimum value of 2 will be used. For any value beyond the upper limit, the maximum possible value will be used. Default value is 8.
long HorizontalOffset Offset from the beginning of the sample buffer to the actual (desired) horizontal start. Default value is zero.
long VerticalOffset Offset from the beginning of the sample buffer to the actual (desired) vertical start. Default value is zero.
BYTE EdgeThreshold The threshold is used to preserve hard edges in the image. If the edge in the video sample is greater than the threshold, then it will be preserved, otherwise it is smoothed. A value of 0 preserves all the edges in the original video sample, while a value of 255 will smooth all the edges. Modify the Threshold value if you want to preserve some edges. If you do not wish to preserve any edges, set EdgeThreshold to 255. This property is only used if the DeblockAlgorithm property is DEBLOCK_FOURLINES. If the DeblockAlgorithm is DEBLOCK_TWOLINES, the EdgeThreshold property is ignored.
VARIANT_BOOL IsLEADInputPinConnected Read only. Gets the filters input pin connection state. Possible values are:
• VARIANT_TRUE - Connected.
• VARIANT_FALSE - Otherwise.
VARIANT_BOOL IsLEADOutputPinConnected Read only. Gets the filters output pin connection state. Possible values are:
• VARIANT_TRUE - Connected.
• VARIANT_FALSE - Otherwise.
long InWidth Read only. Gets the input video stream width in pixels. Should hold the same value as the OutWidth property.
long InHeight Read only. Gets the input video stream height in pixels. Should hold the same value as the OutHeight property.
long OutWidth Read only. Gets the output video stream width in pixels. Should hold the same value as the InWidth property.
long OutHeight Read only. Gets the output video stream height in pixels. Should hold the same value as the InHeight property.
long InBits Read only. Gets the input video stream bits per pixel. Should hold the same value as the OutBits property.
long OutBits Read only. Gets the input video stream bits per pixel. Should hold the same value as the InBits property.
