Abstract:
Aspects of the disclosure provide methods and apparatuses for video encoding/decoding. In some examples, an apparatus for video decoding includes processing circuitry that determines, from a coded video bitstream, a portion of a block is subject to a zero-out operation based on a threshold number of samples being less than a number of samples in one of a height dimension or a width dimension of the block. The processing circuitry determines whether a mixture of a lossless coding mode and one or more lossy coding modes is allowed in the coded video bitstream. The processing circuitry reconstructs the block based on the one or more lossy coding modes in response to (i) the mixture of the lossless coding mode and the one or more lossy coding modes being allowed in the coded video bitstream and (ii) the portion of the block being subject to the zero-out operation.
