1. A video decoding method, performed by a video processing device, the method comprising:
obtaining, from video frames that have been decoded, reference decoding parameters of a reference frame associated with a target video frame, the reference decoding parameters comprising two or more of the following: (i) a reciprocal of a ratio between a quantity of blocks in the reference frame that are decoded in a skip mode and a total quantity of blocks in the reference frame, (ii) a ratio of a first quantity of intra-frame decoded blocks to a second quantity of inter-frame decoded blocks in the reference frame, (iii) an energy parameter of a motion vector (MV) in the reference frame, and (iv) a ratio between a quantity of blocks of a first size in the reference frame and a quantity of blocks of a second size in the reference frame, the first size being less than the second size;
obtaining a decoding indication parameter by performing weighted summation on the two or more reference decoding parameters, and determining a target resolution based on the decoding indication parameter; and
decoding the target video frame by using the target resolution.
