DEBLOCKING FILTER FOR VIDEO CODING AND PROCESSING

A video decoder configured to obtain a first reconstructed block of video data that includes a first sample with a first value; apply deblocking filtering to the first reconstructed block to create a deblocking filtered block; determine a first clipping value for the first sample based on a location of the first sample relative to a boundary of the reconstructed block and based on a size of the reconstructed block; compare the first clipping value to an amount of modification to the first sample caused by the deblocking filtering; in response to the amount of modification to the first sample caused by the deblocking filtering being greater than the first clipping value, modify the first value by the first clipping value to determine a first filtered value for the first sample; and output a deblocking filtered block of video data with the first sample having the first filtered value.
