Abstract
A reference frame selection method and apparatus, a device, and a medium, relating to the field of video coding. The method includes: acquiring m candidate reference frames of a target coding unit, the target coding unit being one of a plurality of coding units of a video frame, m being an integer greater than 1; scoring the m candidate reference frames based on quality score information of the m candidate reference frames, the quality score information indicating coding quality of the target coding unit performing inter-frame prediction through the m candidate reference frames; and selecting an optimal reference frame of the target coding unit according to scoring results of the m candidate reference frames. The described technical solution simplifies the process of determining the optimal reference frame, and greatly accelerates the coding speed of the target coding unit.
