A method for frame extraction processing of a video includes obtaining an encoded image of a video sequence; obtaining presentation time stamps (PTSes) and non-reference frame flags of the encoded image, wherein the encoded image has an encoding structure with time domain levels; determining frame dropping positions of the video sequence based on the time domain levels, the PTSes, and the non-reference frame flags; and performing a frame extraction operation on the video sequence based on the frame dropping positions.
