摘要:
A method performed by a video decoder includes receiving a coded video bitstream that includes a current picture with at least one block located at a boundary of the current picture. The method includes determining whether boundary filtering is enabled for the at least one block based on a syntax element in the received coded video stream. The method further includes, based on a determination that the boundary filtering is enabled: filtering one or more boundary samples corresponding to the at least one block to generate one or more filtered samples, and decoding the at least one block based on the generated one or more filtered samples. The method further includes based on a determination that the boundary filtering is not enabled, decoding the at least one block without filtering the one or more boundary samples.
