A method, apparatus, and computer-readable storage medium for coding multimedia data with adaptive reference frame management. The method codes a current multimedia frame using a corresponding long-term reference frame to obtain a current coded multimedia frame. Coding quality is obtained for the long-term reference frame and calculated for the current coded multimedia frame. The type of the current coded multimedia frame is determined based on motion vectors of its coding blocks. The long-term reference frame is updated based on the coding quality of both frames and the frame type. Subsequent multimedia frames are then coded using the updated long-term reference frame, enabling improved coding efficiency through intelligent reference frame adaptation.
