Code rate reduction processing method for data file and server

Abstract

The embodiment of the invention discloses a code rate reduction processing method for a data file and a server, which can reduce the download delay of a user and reduce the load added by multiple queries of a server. The method includes the following steps that: the server receives an upload application request sent by a first client; the server queries a second-transmission index from a storage warehouse according to the upload application request, wherein the second-transmission index is used to record associated information of fileids of a plurality of original data files pre-stored in thestorage warehouse and a fileid of a corresponding code rate-reducing data file; if the second-transmission index is hit, the server sends a first second-transmission hit instruction to the first client, wherein the first second-transmission hit instruction includes a second fileid; the server receives a first download application request sent by a second client; and the server acquires a first code rate-reducing data file from the storage warehouse according to the second fileid, and sends the first code rate-reducing data file to the second client.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data file code reduction processing method and a server. Background technique [0002] With the rapid development of network and multimedia technology, the demand of users to watch video content through the network has been more and more widely used. In the prior art, users can transmit video files when using social tools to chat, in order to reduce the number of video files To download the traffic required, social servers usually need to downcode the video files uploaded by users. [0003] In the prior art, the code reduction method designed by the social server for video files may include the following steps: user A uploads the original video file to the social server, the social server transcodes the original video file, and stores the newly generated video file with reduced code rate At the same time, the server records the association index between the fileid of the ori...

Problems solved by technology

[0004] In the above existing technologies, the traditional solution queries the associated index every time the user requests a download, which increases the user's download delay

In addition, in a group chat scenario, usually the number of downloads of video files is dozens of times that of uploaded files. For each user's download request, the social server needs to query the associated index once, so there is still a need to query the associated index during the download phase The problem of request amplification, that is, it is necessary to repeatedly query the fileid shared by the same user, which increases the load on the social server
