Abstract
A video coding method includes obtaining an input video frame; determining down-sampling information corresponding to the input video frame in response to determining that a target processing manner corresponding to the input video frame is a down-sampling processing manner; encoding the input video frame according to the down-sampling information to obtain encoded data corresponding to the input video frame; and adding the down-sampling information to the encoded data according to a processing range corresponding to the down-sampling information. The down-sampling information is capable of identifying at least one of a down-sampling proportion and a down-sampling method for the input video frame or identifying a rule for identifying the at least one of a down-sampling proportion and a down-sampling method.
