Embodiment 1

[0132] When the encoding method is applied in practice, take the server-side encoding the mask data as an example, the streaming end transmits the video information to the server through the wireless network, the streaming end watches the live video through the wireless network or wired network, and pulls the video information to the server. The user at the streaming end transmits the sent bullet screen information to the server, and the server processes the video information using the encoding method of the above embodiment to generate mask data, and then forwards the streaming media data carrying the mask and the corresponding bullet screen data through the network. To the streaming end, the streaming end uses the above decoding method to decode the bullet screen data, so that the user of the client can watch the video with the masked bullet screen and improve the user experience.

Embodiment 2

[0134] When the encoding method is actually applied, take the client using the encoding method to encode the mask data file as an example, the client extracts the mask data in the online or offline video file, and uses the above encoding method to encode the mask data, The mask data is packaged into streaming media data and sent to the server; after receiving the streaming media data carrying the mask data, the server decodes and restores the mask data file by using the decoding method in the above embodiment.

Abstract

The invention discloses encoding and decoding methods, computer equipment and a readable storage medium, and belongs to the field of multimedia file structures. According to the encoding method provided by the invention, each target data and the corresponding type are encoded according to the target data in the scalable vector graphic file and the corresponding type, and the binary file marked with the target data type is generated, so that the data compression rate is improved, the data storage space is saved, and the data transmission is facilitated. The decoding method comprises the following steps: decoding each key value pair in a binary file marked with a target data type one by one; according to the type of the key in the key value pair, the value corresponding to the key is effectively converted into the target data corresponding to the type of the key, so that the scalable vector graphic file is restored, and the integrity of the data is ensured.

Description

technical field [0001] The present invention relates to the field of multimedia file structures, and in particular to encoding and decoding methods, computer equipment and readable storage media. Background technique [0002] At present, most Scalable Vector Graphics (SVG for short) use Extensible Markup Language (XML for short) to describe two-dimensional vector graphics. SVG graphics are scalable and can maintain their graphic quality when changing sizes. SVG can use some predefined shape elements to describe graphics, such as: rectangles, lines, paths, etc. XML, a subset of the Standard Universal Markup Language, is a markup language used to mark up electronic documents to make them structured. XML can be used to mark data, define data types, and is a source language that allows users to define their own markup language. XML is a cross-platform, content-dependent technology in the Internet environment and an effective tool for processing distributed structured informat...
