Description
Technical field
The invention belongs to field of computer technology, particularly relate to a kind of video file captions automatic patching system and
Method.
Background technology
Video playback is the most popular a kind of application in current network, regards for foreign films, TV play etc.
Frequently content, captions are piths of video playback, on the one hand make to be ignorant of the spectators of language in video
The sound in former video can be heard, it is understood that video content, it is also possible to effectively help audition
More weak spectators understand video content.
The Video coding supported due to different terminal equipment is different, and therefore, video to be played needs to carry out turning
Code complies with the form that terminal unit is supported.Encoded video transcoding (Video Transcoding) refers to
The video code flow of compressed encoding is converted into another kind of video code flow, with adapt to the different network bandwidth,
The terminal of different disposal ability and different user's requests.Now widely used transcoding operation, Yi Zhongshi
Local transcoding software is utilized to carry out transcoding；Another kind is cloud transcoding technology, is also called off-line transcoding technology, tool
Body refers to be converted into video by server (high in the clouds) the cloud meter of the video format of applicable played
Calculation technology.
Video file on playback terminal can utilize player obtain the captions of coupling from rear server and close
Connection, but, in the prior art, the video file after transcoding cannot be with former video file (before transcoding
Video file) captions carry out Auto-matching and association, cause the former video file cannot be with the mesh after transcoding
Mark video file carries out subtitle file to be shared so that playback terminal need to re-start captions coupling,
Obtain and import, reduce the response speed that player is asked for captions, and then have impact on video playback
Effect.
Summary of the invention
The purpose of the embodiment of the present invention is to provide a kind of video file captions automatic patching system and method, purport
Subtitle file cannot be carried out with the target video file after transcoding due to prior art Central Plains video file in solution
The problem shared.
The embodiment of the present invention is achieved in that a kind of video file captions automatic patching system, described system
Including caption database and off-line transcoding task management server, wherein:
Off-line transcoding task management server, the target after calculating the success of original video files off-line transcoding
The First Eigenvalue that video file is corresponding, sets up Second Eigenvalue corresponding to described original video files, described
The mapping of subtitle file that original video files is corresponding and the First Eigenvalue corresponding to target video file is closed
Described mapping relations are saved in caption database by system；
Caption database, for storing Second Eigenvalue corresponding to original video files, described original video literary composition
Subtitle file that part is corresponding and the mapping relations of described the First Eigenvalue.
The another object of the embodiment of the present invention is to provide the video file of video file captions automatic patching system
Captions automatic matching method, described method comprises the steps:
Video playback client obtains the eigenvalue of video file to be played, by the feature of video file to be played
Value is sent to subtitle server to obtain the subtitle file of coupling；
Subtitle server sends over the eigenvalue of video file to be played according to described video playback client,
The eigenvalue of video file to be played is searched in captions are according to the mapping relations of library storage；
When finding the eigenvalue of video file to be played, return to be played to described video playback client
The subtitle file of the eigenvalue association of video file.
The embodiment of the present invention increases off-line transcoding task management server and captions on the basis of existing technology
Data base, is set up by off-line transcoding task management server and caption database and storage original video files
Subtitle file that corresponding Second Eigenvalue, original video files are corresponding and target video file corresponding the
The mapping relations of one eigenvalue, achieve captions between the target video file after former video file and transcoding
Sharing of file, thus the video file after off-line transcoding and original video files subtitle file are carried out automatically
Association so that playback terminal, without re-starting the coupling of captions, obtaining and import, improves player pair
The response speed of captions request, and video display effect.
