Abstract
This application provides a method and an apparatus for constructing a motion information list in video encoding and decoding and a device, which relates to the field of video encoding and decoding technologies. The method includes: constructing a space domain motion information list, the space domain motion information list including motion information of a space domain neighboring block of a current block, and the space domain neighboring block including at least an intra string copy (ISC) block; and obtaining at least one piece of motion information from the space domain motion information list when motion information in a candidate motion information list is insufficient, and filling the candidate motion information list using the at least one piece of motion information. According to this application, by filling the candidate motion information list using the space domain adjacent motion information when the motion information included in the candidate motion information list is insufficient, content of the candidate motion information list is expanded, so that more displacement vectors that are more effective are provided in the candidate motion information list to achieve a better displacement vector prediction effect, thereby improving the video compression performance.
