Abstract
The invention discloses a method and system for optimizing media-on-demand based on real-time file format conversion, and realizes transmission of a small data set video file header through quick file format conversion, so that the repeated multiplexing of a file by a server can be realized. The method adopts a technical scheme as follows: a client transmits an http request of a file to a server; and after receiving the http request, the server analyzes the http request to find out the file corresponding to the http request; and after determining that the network broadcasting quality of the file is lower than an expected value, the server starts real-time file format conversion, converts the data encapsulation format of the file to maintain basic coding and decoding information in accordance with file transmission in a file header, and transmits the file subjected to the data encapsulation format conversion to the client to play.
Description
Technical field
The present invention relates to the optimisation technique of streaming media on demand, relate in particular to the method and system of optimizing streaming media on demand by the real-time files format conversion.
Background technology
VOD (video on demand) based on http protocol is current popular streaming media on demand mode, and the user can watch the video file (mp4, flv etc.) of various forms in this way.When client need be play certain video, send the http request by player to http-server, server sends to client with video file by the http agreement after the request of receiving.
Existing this mode has the following disadvantages:
(1) the different file encapsulation format of identical video/audio have different emphasis aspect broadcasting performance.Some encapsulation format leaves all coding/decoding informations, broadcast information in file header, and the performance excellence that this form is play in this locality is swift in response when dragging at random; Some form then only is placed on file header with the most basic coding/decoding information, and this form lays particular emphasis on netcast and uses, and plays to begin response rapidly.In the vod system,, then at first must send the head of a big data quantity if transmission is the file of first kind of form, and the duration of file is long more, and this stature is just big more, under the network condition of low speed, the time of playing the required wait of beginning is also long more, and user experience is subjected to very big influence.
(2) video server need be supported the playing request of different players usually, and the form of different player requests is often different, in order to satisfy various players, server need be stored the file of many parts of different-formats, though these files to look audio content just the same.This just has a very big requirement to memory space.
(3) video code conversion of ordinary meaning need be decoded, recode the video/audio data, and this process will expend a large amount of cpu computational resources, and especially for senior coded system (as h264), decoding again, encoding calculation amount is very huge.Therefore, this mode is very high for the requirement of computing capability on the one hand, and owing to complexity of calculation, real-time also can not get guaranteeing completely on the other hand.
Summary of the invention
The objective of the invention is to address the above problem, a kind of method of the optimization streaming media on demand based on the real-time files format conversion is provided, realized the transmission of small data quantity video file head can realizing the repeatedly multiplexing of a file of server by the conversion of file format fast.
Another object of the present invention is to provide the method for another kind based on the optimization streaming media on demand of real-time files format conversion, realized the transmission of small data quantity video file head can realizing the repeatedly multiplexing of a file of server by the conversion of file format fast.
Another purpose of the present invention has been to provide a kind of system of the optimization streaming media on demand based on the real-time files format conversion, has realized the transmission of small data quantity video file head can realizing the repeatedly multiplexing of a file of server by file format conversion fast.
