Multimedia resource coding and multimedia stream decoding methods and devices, equipment and medium

Abstract

The invention discloses multimedia resource coding and multimedia stream decoding methods and devices, equipment and a medium, and belongs to the field of network technology. The method comprises: acquiring, according to a picture feature of a multimedia resource to be coded, a target prediction mode set, the target prediction mode set comprises a partial prediction mode; acquiring, from the target prediction mode set, a prediction mode corresponding to each prediction unit in the multimedia resource; and coding the multimedia resource according to any one of the picture feature and the targetprediction mode set of the multimedia resource and the prediction mode corresponding to each prediction unit to obtain a multimedia stream, each prediction unit carrying identification information ofthe corresponding prediction mode. The identification information of the prediction mode carried by the multimedia stream is short, so that the number of bits occupied by the identification information is reduced, the code rate of the multimedia resource code is reduced, and the burden of coding, decoding or transmission of the multimedia resource is also reduced.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a multimedia resource encoding and multimedia stream decoding method, device, equipment and medium. Background technique [0002] With the development of network technology and the diversification of terminal functions, people can collect multimedia resources through multimedia resource collection equipment, and encode multimedia resources, and then send multimedia streams, and decoding equipment can decode the received multimedia streams . Wherein, the multimedia frame may be an image frame or a video frame. Generally, in the above encoding and decoding process, it is usually necessary to perform intra-frame prediction on the multimedia frame. Among them, the intra-frame prediction refers to the process of predicting the value of the encoded pixel or the decoded pixel and the value of the pixel to be encoded or the pixel to be decoded by using the spatial correlation ...
