Design Of Batch Audio/Video Conversion Platform Based On JavaEE

With the rapid development of digital publishing industry,audio and video publishing direction presents a variety of audio and video file coding standards,data and other significant features of massive.As the amount of data and data types is very large,how quickly and efficiently converted into a unified coding format for the publishing agency is a great problem.Based on the architecture of Spring + SpringMVC + Mybatis,this paper proposes a distributed audio and video format conversion platform with B/S structure combined with open source FMPEG format conversion tool.Based on the java language,this paper analyzes the key technologies and strategies designed in the process of platform architecture design,and develops an efficient audio and video format conversion system,which consists of "core dispatch server","conversion server" and "database".To solve the batch audio and video format conversion,this paper adopts the way of server cluster,discusses several key technologies of how to deploy cluster conversion server involved effectively;in order to guarantee the operation rights of different users,the paper studies the authority control system of the platform;in order to improve the transmission efficiency between the client and the server,this paper makes a comprehensive comparison and study of the advantages and disadvantages of various file transmission methods;in order to improve the accuracy and efficiency of audio and video file format conversion,different format conversion tools are studied in depth.The main innovations in this paper are as follows:(1)In audio and video processing,through the processing of audio and video files,the problem of low conversion efficiency when a single file is too large is solved.Firstly,we classify the audio and video files,then we extract the large audio or video files from the single file based on the algorithm,after that,the segmented files are merged separately and transformed into audio-video files.(2)In the transfer server scheduling,combined with the consistency Hash algorithm,the effective allocation problem of conversion task is effectively solved when the server cluster is converted.In the multi transformation server cluster,we use the consistent Hash algorithm to assign the transformation task to each server equally,so that each transformation server can be effectively utilized.At the same time,when the number of servers changes,the Hash calculation is not needed again,which effectively improves the stablilty and expansibiity of the system.In order to verify the proposed batch audio and video format conversion platform is efficient and available,this paper designs the test scheme and compares the traditional transformation methods.The test results show that,compared with the ordinary audio and video conversion scheme,the use of batch audio and video format conversion platform can effectively improve the conversion efficiency of audio and video files,and reduce the complexity of the work.Practice has proved that the key technology discussed in this paper can be applied in the field of large batch file processing,and has certain practical application value.
