LEAD Video Deblocking Filter

The LEAD Video Deblocking filter is a DirectShow transform filter that performs deblocking on a video stream. The deblocking is applied to raw RGB data and is not related to a specific decoder output. The filter accepts block size and first block offset parameters to deblocking paths and the beginning of the blocked area. If the block size and first block offset do not match the blocks in the passed video sample, the filter is not expected to give satisfactory results. Two algorithms are currently offered to perform deblocking, 2-Lines and 4-Lines. The filter exposes its functionality through both user and programming interfaces.
