Video coding method and device, video decoding method and device, electronic equipment and storage medium

The invention provides a video coding method and device, a video decoding method and device, electronic equipment and a storage medium. The video coding method comprises the following steps: acquiring a motion information candidate list of a current block; performing offset processing on each candidate motion vector in the motion information candidate list to obtain an extended motion vector set; selecting a target extended motion vector from the extended motion vector set as a predicted motion vector of the current block; obtaining coding information of the current block based on the predicted motion vector of the current block; wherein under the condition that the plurality of candidate motion vectors comprise the bidirectional motion vector, a plurality of candidate offset strategies of the bidirectional motion vector are acquired, and the plurality of candidate offset strategies comprise a plurality of offset strategies of offset in the same direction, offset in the opposite direction and zero offset for
