System and method for realizing cloud transcoding on various code rates and encoding formats of audio and video contents

Abstract

The invention relates to a system and a method for realizing cloud transcoding on various code rates and encoding formats of audio and video contents. The system comprises a cloud publishing subsystem for displaying an audio and video publishing interface, a cloud storage subsystem for storing transcoded files, and a cloud transcoding subsystem which comprises a transcoding factor library, a transcoding preprocessing module and transcoding modules, wherein the transcoding preprocessing module is used for analyzing formats of audio and video files selected during cloud publishing, decoding the audio and video files and calling corresponding transcoding function units from the transcoding factor library to form the corresponding transcoding modules. According to the system and the method for realizing the cloud transcoding on various code rates and the encoding formats of the audio and video contents, by the adoption of the structure, the transcoding modules can be assembled according to a transcoding requirement selected during the cloud publishing; each transcoding module has different functions; a large-scale transcoding demand is met, and various audio and video encoding formats and files with various code rates can be generated; the transcoding speed is greatly increased, the transcoding rate is improved, and a large application range is realized.

Description

technical field [0001] The present invention relates to the technical field of file transcoding, in particular to the field of transcoding of various code rates and encoding formats of audio and video content based on cloud computing, and specifically refers to a cloud transcoding that realizes multiple code rates and encoding formats of audio and video content systems and methods. Background technique [0002] The development of new media will be a new trend in the development of future media. The Internet audio and video industry is also developing rapidly, and the demand for audio and video files is increasing. At the same time, different platforms and terminals require audio and video with different encoding formats and bit rates. File, audio and video transcoding work is an indispensable work. [0003] In the existing transcoding technology, there are still the following deficiencies: [0004] 1. The transcoding efficiency of a single transcoder is low, which can no l...

AI Technical Summary

Problems solved by technology

[0004] 1. The transcoding efficiency of a single transcoder is low, which can no longer meet the needs of the rapid development of the current audio and video industry;

[0005] 2. The current cloud transcoding system uses multiple transcoders, but the collaboration between transcoders is inefficient, and it cannot solve the problems of uploading files from multiple terminals and generating files with multiple bit rates and multi-coding formats at the same time. ;

[0006] 3. The current cloud transcoding system rarely cooperates with cloud storage and cannot make cloud transcoding more efficient
