Claim 14:
15. An apparatus for processing video data, comprising:
at least one memory; and
at least one processor coupled to the at least one memory, the at least one processor being configured to:
obtain the video data comprising one or more pictures;
obtain a first block of a picture from the one or more pictures, the first block being located in a first slice of the picture;
determine that a second block is located at a top-left corner of the first block in a second slice of the picture, the second block including one or more pixels for use in performing loop filtering of a pixel of the first block;
determine that loop filtering across slice boundaries is disabled;
determine, based on the second block being located in the second slice and the loop filtering across slice boundaries being disabled, that the one or more pixels of the second block are unavailable for performing the loop filtering of the pixel of the first block; and
based on the one or more pixels of the second block being unavailable for performing the loop filtering of the pixel of the first block, use pixels of a third block of the first slice to replace the one or more pixels of the second block for performing the loop filtering of the pixel of the first block based on a converted slice boundary generated at a left border of the first block using a function modifying a variable associated with a left vertical boundary position.
