Deblocking of subblock boundaries for affine motion compensated coding

Abstract:

An example device for decoding video data includes memory configured to store the video data and one or more processors implemented in circuitry and communicatively coupled to the memory. The one or more processors are configured to determine whether a coding mode for a current block of the video data is an affine mode. The one or more processors are also configured to determine whether pattern refined optical flow (PROF) is enabled in the sequence parameter set (SPS) for the current block. Based at least in part on the coding mode for the current block being the affine mode and PROF being enabled in the SPS for the current block, the one or more processors are configured to disable a deblocking filter for subblock boundaries of the current block and decode the current block with the deblocking filter disabled for the subblock boundaries of the current block.
