Abstract

The present application relates to an encoding method and an encoding device, a decoding method and a decoding device, and a storage medium. Specifically, an encoding method for motion information predictor index, the method comprising: generating a list of motion information predictor candidates; in the case of using affine merge mode, selecting one of the motion information predictor candidates in the list as an affine merge mode predictor; in the case of using non-affine merge mode, selecting one of the motion information predictor candidates in the list as a non-affine merge mode predictor; and using CABAC encoding to generate a motion information predictor index for the selected motion information predictor candidate, one or more bits of the motion information predictor index being bypass CABAC encoded.
