The invention concerns a method for encoding a video stream, an associated method for decoding a video stream, an associated encoder, an associated decoder and associated computer programs. The encoding method is directed to encoding a video stream comprising at least one video sequence, comprising, for the encoding of a square or rectangular block of a picture of a video sequence of the video stream, selecting a motion information predictor for said block from a list of candidate motion information predictors, and entropic encoding of an index representative of a position of the selected motion information predictor in said list. The encoding method further comprises computing statistics representative of a frequency of selection of each motion information predictor of said list on a first portion of a current video sequence, and, for a current block to encode of a second portion following said first portion of the current video sequence, selecting a current motion information predictor for said current block, and entropic encoding of an item of information representative of said selected current motion information predictor, said item of information and/or said entropic encoding being dependent on said computed statistics. |
