Abstract
The invention discloses cloud transcoding method and system for video files and aims to greatly increase transcoding speed and improve transcoding efficiency. According to the technical scheme, the method includes: segmenting a video file into a plurality of intermediate-format files recognizable to transcoders; distributing the segmented intermediate-format files to multiple transcoders; and merging the transcoded files.
Description
Technical field
The present invention relates to the file code-transferring method, relate in particular to code-transferring method and the system for video file that can significantly improve transcoding speed.
Background technology
Video file has the Multi-encoding form, the form of dissimilar player supports also is not quite similar, therefore the provider of internet video business is in order to satisfy the video playback demand of the user on the different platform, often the coded format of video file need to be changed, video code conversion work is the work of Internet enterprises normalization.
In the prior art; when carrying out transcoding; same video file is undertaken by a transcoding machine; but the defective of this code-transferring method also is apparent; when this video file is very huge; the time that transcoding needs will become very long, often can be because transcoding delays the time that new video is shown.
Summary of the invention
The object of the invention is to address the above problem, a kind of cloud code-transferring method and system of video file is provided, can significantly improve transcoding speed, promote transcoding efficiency.
Technical scheme of the present invention is: the present invention has disclosed a kind of cloud code-transferring method of video file, comprising:
Be the file of a plurality of intermediate forms that can be identified by the transcoding machine with the video file cutting;
Carry out transcoding for many transcoding machines the file allocation of a plurality of intermediate forms after the cutting;
File behind the transcoding is synthesized.
According to an embodiment of the cloud code-transferring method of video file of the present invention, the cutting process of video file further comprises:
Video file is divided into a plurality of video-frequency bands;
From the file header of video file, find respectively the description document corresponding with each video-frequency band;
Each video-frequency band and corresponding description document are synthesized the file of intermediate form.
The present invention has disclosed a kind of cloud trans-coding system of video file, comprising:
The video file cutting device is the file of a plurality of intermediate forms that can be identified by the transcoding machine with the video file cutting;
File transcoding distributor carries out transcoding for many transcoding machines the file allocation of a plurality of intermediate forms after the cutting;
Transcoding file synthesis device synthesizes the file behind the transcoding.
According to an embodiment of the cloud trans-coding system of video file of the present invention, the video file cutting device comprises:
The video-frequency band cutting unit is divided into a plurality of video-frequency bands with video file;
Description document is searched the unit, finds respectively the description document corresponding with each video-frequency band from the file header of video file;
The intermediate file synthesis unit synthesizes each video-frequency band and corresponding description document the file of intermediate form.
The present invention contrasts prior art following beneficial effect: the solution of the present invention is the file that former video file is cut into a plurality of intermediate forms, carry out transcoding for many transcoding machines the file allocation of a plurality of intermediate forms after the cutting, at last the video file behind the transcoding is synthesized.Compared to prior art, the solution of the present invention can significantly improve transcoding speed, promotes transcoding efficiency, has avoided delaying the time that new video is shown because of the transcoding overlong time.
Description of drawings
