Abstract
An inter prediction method is provided, including: obtaining a first reference frame index and a first motion vector of a to-be-processed block (); deriving a second reference frame index from the first reference frame index, where the second reference frame index is different from the first reference frame index (); scaling the first motion vector to obtain a second motion vector (); obtaining a first reference block of the to-be-processed block according to the first reference frame index and the first motion vector (); obtaining a second reference block of the to-be-processed block according to the second reference frame index and the second motion vector (); and weighting the first reference block and the second reference block to obtain a combined prediction block (). Each reference list for inter prediction is allowed to include two groups of motion information, which helps improve an inter prediction effect.
