[embodiment]
Be further detailed below in conjunction with accompanying drawing.
Need that manual loading is preprepared dubs file for solving when playing media file, the problem that inconvenient user uses, propose a kind of can the media file playing method of automatic dubbing.
Embodiment one
As shown in Figure 1, be the media file playing method flow chart of the present embodiment.The method comprises the steps:
S10: loading medium file.Media file is the data acquisition system of relevant information including sound, image information and this sound or image.Media file exists with certain file format according to the difference of coded system and application, media file format comprises MOV, AVI, RMVB, WMV, MP4, RAM, RA, MPG, VCD and DVD etc., after media file is loaded, can output sound, image obtain the relevant information (such as coded system, code check, duration etc.) of sound or image.
S20: the media file information gathering described media file.Media file information comprises the various information of media file, and the relevant information of the sound that some media file information can directly be comprised by media file itself or image obtains, as file name, file format, file duration etc.; Other obtain, as file cryptographic Hash after then needing the data comprised media file to carry out certain process.
File name generally can the content that comprises of presentation medium file, sometimes can search media file according to file name, but due to media file can rename, reliably dependent file title can not determine a media file.
File cryptographic Hash (HASH) is the numerical value that content-data according to media file (as single view data or view data and voice data) is obtained by certain logical operation, different files is because content-data difference (even if filename is identical) its cryptographic Hash comprised is different, identical file (even if filename was modified) its cryptographic Hash is also constant, therefore file cryptographic Hash can prove as the uniqueness of file, and the cryptographic Hash of identical file is stable and unique.File cryptographic Hash can also be used to carry out file verification.As after transmission file, judge that whether file is complete by the method for cryptographic Hash contrast.
In a preferred embodiment, media file information can further include more information, as included but not limited to following content: file format (showing the packaged type of media file), file size (showing the number of media file data amount and shared memory space), file duration (showing the time according to normal speed forward these media file needs complete), video information (as Video coding mode), audio-frequency information (as audio coding mode), whether have and external dub file (show whether have corresponding with this media file dub file) and external cryptographic Hash (for uniquely determining that this dubs file) of dubbing file.More detailed information is conducive to obtaining Search Results rapidly and accurately.
S30: uploaded onto the server by described media file information, what acquisition server was passed back according to described media file information dubs file.
Server stores media file media file information and corresponding dub file dub fileinfo.Described media file information, dub fileinfo and dub file association store.Media file and to dub between file be the relation of multi-to-multi.Media file may correspond to multiplely dubs file, as the multi-lingual of a film is dubbed; Dubbing file for one also can corresponding multiple media file (the animation version of such as same portion film and live-action version).Therefore the media file information on server and to dub fileinfo be corresponding stored, just can find according to media file information and corresponding dub file.Following table gives the media file information of server stores and dubs an example of fileinfo: contain media file information in this table as media file name, media file cryptographic Hash, media file size etc., also contains and dub fileinfo as dubbed filename, dubbing file cryptographic Hash etc., and media file information is with to dub fileinfo corresponding.
Can see from upper table, the file name of front 4 files, media file cryptographic Hash, file size and file duration are just the same, are shown to be the file that content is identical.But from dubbing file cryptographic Hash, corresponding to dub file different, wherein sequence number 1 to 3 is Chinese and dubs, and sequence number 4 is dubbed for English.Chinese is dubbed also has mandarin to dub or difference that Guangdong language is dubbed, or is made by different publishers and produce difference etc.
When comprising media file cryptographic Hash in the media file information of player collection, as shown in Figure 2, server returns the step of dubbing file according to described media file information and is specially:
S302: according to the data stored in the file cryptographic Hash retrieval server comprised in described media file information.According to foregoing description, the cryptographic Hash of media file is stable and unique, can prove as the uniqueness of file, therefore adopts the method for file cryptographic Hash contrast retrieval can obtain result accurately.Preferably, primary election can be carried out by file name to the data stored in server, reduce the scope of retrieval.Further preferably, can select again by the data of more media file information to primary election, reduce the scope of retrieval further.
S304: judge whether server stores the media file of identical media file cryptographic Hash corresponding dub fileinfo.If server stores the media file cryptographic Hash that the media file cryptographic Hash uploaded with player is identical, and to should fileinfo be dubbed, then proceed to step S306, otherwise terminate.The data that server stores only can comprise media file information, for the related information set up with dub file, do not need to comprise this media file itself.
S306: according to described dub fileinfo find on server with described dub fileinfo association store dub file, and dub file by this and pass back.Due to media file with dub file and may have and multiplely corresponding dub file, therefore the file of dubbing found all can be returned to player by server, or only returns and dub listed files and select for user.
In above-mentioned processing procedure, utilize file cryptographic Hash to carry out precise search, if there is no a media file of this file cryptographic Hash completely corresponding dub file, then obtain the process of dubbing and just will terminate.And dub requirement not too high occasion to some, the mode of fuzzy search can be adopted to obtain and to dub.In a preferred embodiment, as shown in Figure 3, if judged result is no in step S304, then following steps are carried out:
S308: carry out fuzzy search according to the media file information except file cryptographic Hash.Fuzzy search refers to that media file information such as file name, file duration or the external cryptographic Hash etc. of dubbing file of utilization except this condition of file cryptographic Hash is retrieved in search condition, obtains and dubs file.
Wherein, the cryptographic Hash of dubbing file can dub the relation of file and media file corresponding with it by side light.Such as, media file has an external Chinese to dub in this locality, and user needs the English of this media file to dub, and Chinese server just in time saving this media file is dubbed and is dubbed with English, that dubs file by Chinese dubs file cryptographic Hash, indirectly can find the media file cryptographic Hash of this media file, then find English to dub according to this media file cryptographic Hash.In fact, may corresponding multiple media file owing to dubbing file, and when can not find according to media file cryptographic Hash suitable dub file time, undertaken searching may obtain satisfied result by having the file cryptographic Hash of dubbing of dubbing file.
S310: judge whether to have obtain according to fuzzy search dub fileinfo.If so, then step S306 is proceeded to; Otherwise terminate.
S40: choose and dub file and play with media file synchronization.Player is chosen and is loaded and dub file after obtaining and dubbing file, according to the current time value of playback of media files, makes to dub file and media file synchronization is play.
In further improving, can also before the media file information gathering described media file, judge whether user allows download to dub file, if user allows download to dub file, then gather the media file information of described media file, uploaded onto the server by described media file information, what acquisition server was passed back according to described media file information dubs file; If user does not allow download to dub file, then do not carry out gathering media file information and the upload media fileinfo step to server.
Embodiment two
On the basis of a upper embodiment, after step S10, also comprise and judge whether this locality has the step of dubbing file corresponding with media file.This step is by realizing with under type, and player is by retrieval local folders (file that global search or user specify), and what associate with media file if find that there is dubs file, then this is dubbed file and present to user by selecting interface.Then judge whether that receiving user changes the instruction of dubbing: what media file was embedded dubs and may meet consumers' demand, and also likely existing file of dubbing can not be met consumers' demand, and is therefore necessary to judge that user dubs file the need of replacing.Can add such as the information of " that does not want dubs, and downloads new dubbing " or " do not need to download, leave " in user interface, representative of consumer needs replacing to dub or does not need replacing to dub respectively.If do not receive replacing to dub instruction, show local dub file and can meet consumers' demand, then directly can load broadcasting according to the selection of user, manually search without the need to user and dub file and load, namely directly perform step S40: choose local dubbing file and play with media file synchronization; If receive replacing to dub instruction, then perform step S20 and S30: the media file information gathering described media file, uploads onto the server described media file information, what acquisition server was passed back according to described media file information dubs file.
If what this locality was corresponding with media file dubs file, then perform step S20 and S30: the media file information gathering described media file, uploaded onto the server by described media file information, what acquisition server was passed back according to described media file information dubs file.
If this locality has and corresponding with media file dubs file, dub files passe to server by this locality.If user natively has dub file, but this dubs file only for user oneself.Dub files passe to server by this locality, the file of dubbing of user can be shared, by the participation of user, resource can be made to reach shared.Concrete steps are as follows:
Gather media file information and dub fileinfo.
By described media file information with dub fileinfo and upload onto the server, reception server is according to described media file information and dub the judged result that fileinfo judges whether server stores the identical and media file information of correspondence and dub fileinfo.If described judged result is server store corresponding media file information and dub fileinfo, then terminate to upload.
If described judged result is server do not store corresponding media file information and dub fileinfo, then by this locality dub files passe to server and announcement server will describedly dub file and media file information, dub fileinfo association store.
In a preferred embodiment, at collection media file information with dub fileinfo and before sending the step of server to, also comprise and judge whether user allows to upload to dub Files step.If user forbids uploading, then end operation, dub files passe to server only when user allows to upload just by this locality.
Wherein choose dub file and the step play with media file synchronization with by this locality dub files passe to server step in no particular order, also can carry out simultaneously.
Embodiment three
In the present embodiment, also comprise the step of dubbing file according to the screening that imposes a condition.The all files of dubbing obtained after retrieval on the server may only have part useful concerning user, and also there is no need all results all to return for server, waste unnecessary resource.Therefore the result number returned can be set at server end, and return according to certain strategy that degree of correlation is forward or user evaluates good result.Concrete returns at most 5 results as arranged, and the degree according to media file information retrieval sorts to result, then gets first 5 and returns to player; And in player end, user can impose a condition, the result that server returns further is screened.The condition of user's setting can be exclusion condition or optimum condition, as got rid of the lower file of sound quality or selecting a certain languages etc.
Embodiment four
