Description

In HM6.1, the deblocking filter will disable filtering for the left and top boundaries of a losslessly coded block, while still filtering the bottom and right edges.

It is suggested to replace the following code in HM functions xEdgeFilterLuma and xEdgeFilterChroma:

"#if LOSSLESS_CODING
        // check if each of PUs is lossless coded
        bPartPNoFilter = bPartPNoFilter || (pcCU->isLosslessCoded(uiAbsZorderIdx) );
        bPartQNoFilter = bPartQNoFilter || (pcCU->isLosslessCoded(uiAbsZorderIdx) );
#endif
"

with

"#if LOSSLESS_CODING
        // check if each of PUs is lossless coded
        bPartPNoFilter = bPartPNoFilter || (pcCUP->isLosslessCoded(uiPartPIdx) );
        bPartQNoFilter = bPartQNoFilter || (pcCUQ->isLosslessCoded(uiPartQIdx) );
#endif.
"
