Abstract
This application relates to a video decoding method performed at a computer device. The method includes: obtaining encoded data corresponding to a current video frame; obtaining a processing parameter corresponding to the current video frame; determining a target processing manner corresponding to the current video frame according to the processing parameter, the target processing manner being one of candidate processing manners, the candidate processing manners comprising at least one of a full resolution processing manner and a downsampling processing manner, and the processing parameter being consistent with a corresponding processing parameter in an encoding process; and decoding the encoded data corresponding to the current video frame according to the target processing manner, to obtain a corresponding decoded video frame. In the encoding method, a processing manner for a video frame can be flexibly selected, thereby improving video encoding quality in the case of limited bandwidth.
