Video downloading method, server and clients

Abstract

An embodiment of the invention discloses a video downloading method. The video downloading method includes that a server receives a video downloading request transmitted by an optional client, and the video downloading request comprises a network path of a requested original video file and expected transcoding parameters; the server acquires the original video file requested by the client according to the network path of the requested original video file; the server acquires a transcoding file of the original video file requested by the client according to the expected transcoding parameters and the original video file; and the server returns the transcoding file to the client. The embodiment of the invention further discloses the server and clients. Transcoding files are directly provided for the various clients by the server, so that each transcoding process and a corresponding video downloading process are synchronously completed, the video downloading efficiency is improved, and resource wastage caused by individual video transcoding for each client is eliminated.

Description

Technical field [0001] The present invention relates to the technical field of video downloading, in particular to a video downloading method, server and client. Background technique [0002] Transcoding is the process of converting a video from a format to another format. Transcoding parameters include: a set of data such as output container format, audio and video encoding, and video resolution. Network path refers to any method that can identify a file, such as: http (Hyper Text Transfer Protocol), ed2k (eDonkey2000 network, file sharing network) and other URI (Uniform Resource Identifier) Symbol), or bt (bit torrent, bit stream) seed file. [0003] At present, the formats of the video files that can be downloaded on the Internet are very different. Take the container format (often called the video format) as an example. The container format is a data organization method used to hold the video stream and audio stream of the video file. There are: AVI (Audio Video Interleaved,...

AI Technical Summary

Problems solved by technology

At present, transcoding software that can be applied to clients on the market, such as: FFmpeg (Fast Forward MPEG, an open source free cross-platform video and audio streaming solution), format factory, etc., are all stand-alone software, which cannot be used for the same video files and the same Transcoding parameters transcoding other clients share the same transcoding file. Therefore, in the existing video downloading scheme, after each client downloads the original video file from the server, each client performs the transcoding process independently. It will consume a lot of time, causing users to wait too long; at the same time, the transcoding process for the same video file and the same transcoding parameters is repeated multiple times on each client, resulting in a serious waste of resources
