Abstract
Embodiments of this application relate to the field of video picture coding technologies, and disclose a bidirectional inter prediction method and apparatus, to improve coding efficiency. The method includes: obtaining indication information, where the indication information is used to indicate that second motion information is determined based on first motion information, the first motion information is motion information of a current picture block in a first direction, and the second motion information is motion information of the current picture block in a second direction; obtaining the first motion information; determining the second motion information based on the first motion information; and determining prediction samples of the current picture block based on the first motion information and the second motion information.
