Abstract

A video encoding method, a video decoding method, an apparatus, a device, and a storage medium include parsing a first flag from the video bitstream when a video bitstream is allowed to be decoded by referencing a library picture corresponding to a library picture bitstream, using a value of a target parameter of the video bitstream as a value of a target parameter of the library picture bitstream referenced by the video bitstream when a value of the first flag is a first value, and reconstructing, based on the value of the target parameter of the library picture bitstream referenced by the video bitstream and the library picture bitstream referenced by the video bitstream to obtain the library picture corresponding to the library picture bitstream referenced by the video bitstream.
