[embodiment]
Be further detailed below in conjunction with accompanying drawing.
Need the preprepared file of dubbing of manual loading for solving when the playing media file, the problem that inconvenient user uses proposes a kind of media file playing method that can automatic dubbing.
Embodiment one
As shown in Figure 1, be the media file playing method process flow diagram of present embodiment.This method comprises the steps:
S10: loading medium file.Media file is the data acquisition that includes the relevant information of sound, image information and this sound or image.Media file exists with certain file layout according to the different 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 and obtain sound or the relevant information of image (for example coded system, code check, duration etc.).
S20: the media file information of gathering described media file.Media file information comprises the various information of media file, and the sound that some media file information can be directly comprise by media file itself or the relevant information of image obtain, as file name, file layout, file duration etc.; Other data that then need media file is comprised carry out obtaining after certain processing, as the file cryptographic hash.
The content that file name generally can the presentation medium file be comprised sometimes can be searched media file according to file name, but because media file can rename, can not rely on file name reliably and determine a media file.
File cryptographic hash (HASH) is the numerical value that the content-data (as single view data or view data and voice data) according to media file obtains by certain logical operation, different files is because its cryptographic hash of content-data difference (even filename is identical) that comprises is different, its cryptographic hash of identical file (even filename was modified) also is constant, therefore the file cryptographic hash uniqueness that can be used as file proves that the cryptographic hash of identical file is stable and unique.The file cryptographic hash can also be used to carrying out file verification.As after transmitting file, judge with the method for cryptographic hash contrast whether file is complete.
In a preferred embodiment, media file information can further include more information, as includes but not limited to following content: file layout (packaged type that shows media file), file size (what and the shared storage space that show the media file data amount), file duration (showing time) according to intact these media file needs of normal speed forward, video information (as the video coded system), audio-frequency information (as audio coding mode), whether external file (show whether the dub file corresponding with this media file is arranged) and the external cryptographic hash of dubbing file (be used for unique determine that this dubs file) of dubbing is arranged.More detailed information helps obtaining rapidly and accurately Search Results.
S30: described media file information uploading to server, is obtained server and dubs file according to what described media file information was passed back.
Store the media file information and the corresponding fileinfo of dubbing of dubbing file of media file on the server.Described media file information, dub fileinfo and dub file association storage.Media file and to dub between the file be the relation of multi-to-multi.Media file can corresponding a plurality of files of dubbing, and dub as the multi-lingual of a film; Dubbing file for one also can corresponding a plurality of media file (the animation version and the live-action version of a for example same film).Therefore the media file information on the server is corresponding stored with dubbing fileinfo, just can find the corresponding file of dubbing according to media file information.Following table has provided the media file information of server stores and an example of dubbing fileinfo: comprised media file information such as media file name, media file cryptographic hash, media file size etc. in this table, also comprised and dubbed fileinfo as dubbing filename, dub file cryptographic hash etc., and media file information is with to dub fileinfo corresponding.
| Unique sequence number | Encrypt id | The media file name | The media file cryptographic hash | Media file size (byte) | Media file duration (second) | The media file descriptor | Whether enable | Dub filename | Dub the file cryptographic hash |
| 1 | xyz | Kung Fu Panda | 12345abc de | 4615612764 | 3060 | Be | Kung Fu Panda .Chs.mp3 | sdffasd 23 | |
| 2 | wefd | Kung Fu Panda | 12345abc de | 4615612764 | 3060 | Be | Kung Fu Panda .Chs.mp3 | xxcccc x | |
| 3 | dfs | Kung Fu Panda | 12345abc de | 4615612764 | 3060 | Be | Kung Fu Panda .Chs.mp3 | 9889hg | |
| 4 | sdf | Kung Fu Panda | 12345abc de | 4615612764 | 3060 | Be | Kung Fu Panda .Eng.mp3 | lklsdf | |
| 5 | w3e | Kung Fu Panda 2 | sdfsdfsdf | 453421223 | 3000 | Be | Kung Fu Panda .Chs.mp3 | 32443 2s |
Can see that from last table the file name of preceding 4 files, media file cryptographic hash, file size and file duration are just the same, show it is the identical file of content.But from dubbing the file cryptographic hash, the corresponding file of dubbing but has nothing in common with each other, and 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, is perhaps made producing difference etc. by different publishers.
When comprising the 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 of storing in the file cryptographic hash retrieval server that comprises in the described media file information.According to foregoing description as can be known, the cryptographic hash of media file is stable and unique, and the uniqueness that can be used as file proves, therefore adopts the method for file cryptographic hash contrast retrieval can access result accurately.Preferably, can carry out primary election to the data of storing in the server, dwindle the scope of retrieval with file name.Further preferably, can select again the data of primary election, further dwindle the scope of retrieval with more media file information.
S304: the fileinfo of dubbing of judging the media file correspondence that whether stores identical media file cryptographic hash on the server.If store the identical media file cryptographic hash of uploading with player of media file cryptographic hash on the server, and, then change step S306 over to, otherwise finish dubbing fileinfo.The data of storing on the server can only comprise media file information, are used to set up and the related information of dubbing file gets final product, and do not need to comprise this media file itself.
S306: find on the server and the described file of dubbing of dubbing the fileinfo association store according to the described fileinfo of dubbing, and dub file with this and pass back.Since media file with dub file and may have a plurality of corresponding files of dubbing, so server can all return to player with the file of dubbing that finds, and perhaps only returns and dubs listed files for user's selection.
In the above-mentioned processing procedure, utilize the file cryptographic hash accurately to retrieve, if do not have complete corresponding this document cryptographic hash media file dub file, then obtain the process of dubbing and just will finish.And dub requirement not too high occasion to some, can adopt the mode of fuzzy search to obtain and dub.In a preferred embodiment, as shown in Figure 3,, then carry out following steps if judged result is not among the step S304:
S308: carry out fuzzy search according to the media file information except that the file cryptographic hash.Fuzzy search is meant in search condition that the media file information utilized except that this condition of file cryptographic hash such as file name, file duration or the external cryptographic hash of dubbing file wait and retrieves, obtains and dub file.
Wherein, the cryptographic hash of dubbing file can side light be dubbed the file and the relation of corresponding media file with it.For example, media file has an external Chinese to dub in this locality, and the user needs the English of this media file to dub, and the Chinese of just in time having preserved this media file on the server is dubbed with English and is dubbed, dub the file cryptographic hash by what file dubbed in Chinese, can find the media file cryptographic hash of this media file indirectly, find English to dub according to this media file cryptographic hash again.In fact, may corresponding a plurality of media files owing to dub file, and suitable when dubbing file when can not find according to the media file cryptographic hash, search and may obtain satisfied result by having the file cryptographic hash of dubbing of dubbing file.
S310: judge whether to have according to what fuzzy search obtained and dub fileinfo.If then change step S306 over to; Otherwise finish.
S40: choose dub file and with the media file synchronous playing.After player obtains to dub file, choose and load and dub file, the current time value according to playback of media files makes and dubs file and media file synchronous playing.
In further improving, can also be before the media file information of gathering described media file, judge whether the user allows download to dub file, if allowing to download, the user dubs file, then gather the media file information of described media file, described media file information uploading to server, is obtained server and dubs file according to what described media file information was passed back; Do not dub file if the user does not allow to download, then do not gather media file information and upload media fileinfo step to server.
Embodiment two
On the basis of a last embodiment, after the step S10, also comprise and judge the local step of dubbing file corresponding that whether have with media file.This step can realize in the following manner that player, is then dubbed this file and presented to the user by selecting the interface if find that the file of dubbing related with media file arranged by retrieval local folders (file of global search or user's appointment).Judge whether to receive the user then and change the instruction of dubbing: dubbing that media file is embedded may be met consumers' demand, and also might existingly dub file and can not meet consumers' demand, and is necessary to judge therefore whether the user needs replacing to dub file.Can be in the information of user interface adding such as " that does not want dubs, and downloads new dubbing " or " do not need to download, leave ", representative of consumer need be changed to dub or do not need to change and dub respectively.If do not receive to change and dub instruction, show and local dub file and can meet consumers' demand, then can directly load broadcast, need not the user and manually search and dub file and load, be i.e. direct execution in step S40 according to user's selection: choose local dub file and with the media file synchronous playing; If receive to change and dub instruction, then execution in step S20 and S30: gather the media file information of described media file, described media file information uploading to server, is obtained server and dubs file according to what described media file information was passed back.
