Methods and apparatuses for video decoding, computer device, and storage medium

Abstract

Aspects of the disclosure provide methods and apparatuses for video encoding / decoding, a computer device, and a storage medium. In some examples, an apparatus for video decoding includes receiving circuitry and processing circuitry. The processing circuitry decodes prediction information for a first block in a current picture from a coded video bitstream. The prediction information is indicative of an inter prediction mode that determines a first motion vector for the first block from a motion vector predictor. Then, the processing circuitry constructs, in responses to the inter prediction mode, a candidate list of candidate motion vector predictors with an exclusion from a plurality of second blocks that require one or more operations to finalize second motion vectors for the second blocks during a motion vector derivation. Further, the processing circuitry determines, based on the candidate list of candidate motion vector predictors, the first motion vector for the first block, and then reconstructs the first block according to the first motion vector for the first block.

[0001] Incorporated herein by reference [0002] This application claims priority to U.S. Provisional Application No. 62 / 698,012, entitled "Improved Constraints for Decoder-Side Motion Derivation and Correction," filed July 13, 2018, and filed December 2018 Priority to US Application No. 16 / 232,618, entitled "Method and Apparatus for Video Encoding," filed on the 26th, the entire contents of which are incorporated herein by reference. technical field [0003] The present application relates to video codec technology, and in particular to a video decoding method and device, computer equipment and storage media. Background technique [0004] Video encoding and decoding is possible through inter-picture prediction techniques with motion compensation. Uncompressed digital video may include a series of pictures, each picture having a spatial dimension of, for example, 1920x1080 luma samples and associated chrominance samples. The series of pictures has a fixed or variable pictu...
