Method and apparatus for processing video stream, method for generating video stream

Abstract

The application discloses a video stream processing method and device, and a video stream generation method. The method comprises the following steps: receiving an input video stream, and generating a target feature vector according to multi-dimensional description information of the input video stream, wherein the multi-dimensional description information is used for describing video content recorded by the input video stream from different dimensions; searching for a candidate memory entry in a first memory bank according to the target feature vector; determining a reconstruction cost generated by a reconstruction operation of the candidate memory entry by using each encoding method; determining a target encoding method from multiple encoding methods according to multiple reconstruction costs corresponding to the multiple encoding methods, extracting to-be-encoded information corresponding to the target encoding method from the candidate memory entry and the input video stream, and executing the target encoding method on the to-be-encoded information to obtain an encoding result; and outputting the encoding result to a decoding end, wherein the encoding result is used for searching for a memory entry in the decoding end.
