Description
Technical field
The invention belongs to the audio frequency and video technical field, relate in particular to parallel code-transferring method of a kind of video burst and system.
Background technology
Along with the fast development of audio frequency and video play-back technology, the user is also increasingly high to the requirement of audio frequency and video playing function.
When video was carried out transcoding, traditional mode was that former video file is cut into slices, and is cut into a plurality of piece of video, then to a plurality of piece of video of cutting out one by one carry out transcoding.For example, for existing big video, suppose that video can cutting 7 sections, every section transcoding needs n second, then 7n after second the user just can watch the video file behind the transcoding.
The shortcoming that above transcoding mode exists is exactly, owing to need carrying out transcoding one by one to a plurality of piece of video, when piece of video more for a long time, will spend great amount of time, cause with the voice playing time inconsistently, user's viewing is caused great influence.
How reducing the transcoding time to video file, improve transcoding efficiency, guarantee the texture of picture, is one of direction of audio frequency and video play-back technology area research.
Summary of the invention
The purpose of the embodiment of the invention is to provide a kind of video burst code-transferring method that walks abreast, and is intended to reduce the transcoding time to video file, improves transcoding efficiency, guarantees the texture of picture.
The embodiment of the invention is achieved in that a kind of video burst code-transferring method that walks abreast, and said method comprising the steps of:
Former video file is decomposed a plurality of first piece of video;
It is second piece of video that a plurality of first piece of video after decomposing are carried out transcoding simultaneously;
A plurality of second piece of video behind the transcoding are combined into the video file of new form.
Another purpose of the embodiment of the invention is to provide a kind of video code conversion device, and said device comprises:
Former video file resolving cell is used for former video file is decomposed a plurality of first piece of video;
A plurality of transcoding modules, being used for simultaneously first piece of video being carried out transcoding is second piece of video;
Composite module is used for a plurality of second piece of video behind the transcoding are combined into the video file of new form.
An also purpose of the embodiment of the invention is to provide a kind of video burst trans-coding system that walks abreast, and said system comprises the video code conversion device that the embodiment of the invention provides.
The embodiment of the invention is through being decomposed into former video file a plurality of first piece of video; It is second piece of video that a plurality of first piece of video are carried out transcoding simultaneously; Second piece of video behind the transcoding is combined as the video file of new form, has not only saved the transcoding time greatly, improved transcoding efficiency; Also well guarantee the texture of picture, be beneficial to the popularization of playing audio/video.

Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
Fig. 1 shows the flow process of the video transcoding method that the embodiment of the invention provides.
In step S101, receive user's transcoding instruction;
In step S102, former video file is decomposed a plurality of first piece of video;
In step S103, it is second piece of video that a plurality of first piece of video after decomposing are carried out transcoding simultaneously;
Wherein, when carrying out transcoding, be that the piece of video after according to the instruction of the transcoding in step S101 former video file being decomposed is carried out transcoding.
In step S104, a plurality of second piece of video behind the transcoding are combined into the video file of new form;
In step S105, the video file of new form is play.
Wherein, it is the very first time that former video file is decomposed one first used time of piece of video, and it is that time of second piece of video was second time that single first piece of video is carried out transcoding, and wherein, the said very first time is less than said second time.
For example, see also Fig. 2, Fig. 2 is for carrying out the sketch map of transcoding to video file.
As far as needing the former video file of transcoding, suppose that the former video file of a slice can be cut to 7 sections, the time that each section cuts out is 1m second, and the time of each section transcoding is 1n second, and 1m is little more a lot of than 1n.Only need just to have begun 1m just can obtain one first piece of video second, just can carry out transcoding to first first piece of video that cuts out this moment; , first first piece of video can continue from former video file, to cut out second first piece of video when being carried out transcoding; Because 1m is little more a lot of than 1n; So need not wait first first piece of video transcoding to accomplish, second first piece of video will be cut out from former video file, and can carry out the transcoding of second first piece of video simultaneously; And by that analogy, cut up to all the other 5 first piece of video.
If 1m＜1n/7 then need not to wait first first piece of video transcoding to accomplish, all the other 6 first piece of video can cut; Then 7 first piece of video transcoding that carries out that can walk abreast is handled altogether, and then the former video file of this sheet is changed, and only needs the time of 1m+1n; And simultaneously the video file behind the transcoding is play, the time that this sheet video file supplies the user to watch is 1P second, 1P is much larger than 1n; And the time of following a slice video file transcoding is much smaller than 1n; So the user need not to wait for the transcoding of video file, directly watch getting final product very convenient user's use.
Fig. 3 shows the structure of the video code conversion device that the embodiment of the invention provides.
Wherein, transcoding command reception module 31 is used to receive user's transcoding instruction;
Former video file resolving cell 32 is used for former video file is decomposed a plurality of first piece of video;
In the practical implementation process, the embodiment of the invention includes a plurality of transcoding modules 33.
Video file playing module 35 is used for the video file of new form is play.
Wherein, it is the very first time that former video file is cut out one first used time of piece of video, and it is that time of second piece of video was second time that single first piece of video is carried out transcoding, and wherein, the said very first time is less than said second time.
The embodiment of the invention also provides a kind of video burst trans-coding system that walks abreast, and said system comprises the video code conversion device that the embodiment of the invention provides, in view of this device in the existing detailed description of preceding text, repeat no more here.
The embodiment of the invention is through being decomposed into former video file a plurality of first piece of video; It is second piece of video that a plurality of first piece of video are carried out transcoding simultaneously; Second piece of video behind the transcoding is combined as the video file of new form, has not only saved the transcoding time greatly, improved transcoding efficiency; Also well guarantee the texture of picture, be beneficial to the popularization of playing audio/video.
The above is merely preferred embodiment of the present invention, not in order to restriction the present invention, all any modifications of within spirit of the present invention and principle, being done, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
