Specifically, the present embodiment media playing apparatus can apply to mobile phone, panel computer, palm PC PDA or notes The mobile terminals such as this computer, can also be applied to the fixed terminals such as digital TV, desk computer, and the present embodiment is not limited to this System.The present embodiment is illustrated with mobile phone.
The present embodiment is provided with media play application software, such as media player in the terminals such as mobile phone, and which is played Media file can be audio file, video file or audio-video document.
Media player often relies on the multimedia database (hereinafter referred to as media database) in terminal system.
Wherein, correspondence media database, is generally provided with media folder, in terminal system for storing corresponding matchmaker Body file, in multimedia database, essential record has the store path of each media file in media folder, file name, file Size, file duration, file type etc., additionally, when multimedia database is also played for media file additional maintenance media The parameter informations such as length, remarks, label (TAG).
When user starts media application software playing audio-video document, media application software can call media data first The media file information recorded in storehouse, then, goes to call media file by the media file information recorded in media database Corresponding media file in folder, so as to show corresponding image, realizes media play.
As existing media application software depends on the media database of system, the media file under media folder By the third-party application modification outside media application, (such as third party application has carried out renaming, modification to media file Remove/move into and operate Deng operation, or SD card (Secure Digital Memory Card, safe digital card)) after, it is impossible to will Record, media play list in media database and the file under system each media folder carry out real-time synchronization.Now, When playing, there is some of media database record, corresponding media file cannot be found by its store path, caused Poor user experience.Further, since media player is media file additional maintenance media playing duration, remarks, label TAG Etc. information, user is not intended to these information and is deleted.
In order to avoid above-mentioned situation, the present embodiment is set with corresponding trigger condition, to be scanned to media file, leads to Overscanning obtains media file information and the media file information in media database in terminal system media folder, with Just the file under the record in media database, media play list and system each media folder is carried out into real-time synchronization, Ensure concordance, the integrity of media file information, lift Consumer's Experience.Wherein, when being scanned, for media database In there is no the record of media file, do not perform deletion action, but update the data storehouse, this record is set to into un-activation shape State, and playlist is updated, hide non-existent media file.
In the present embodiment, the media file information can include：When the filename of media file, store path, file Whether the last modification time of length, file size, file and/or file activate, and file playing duration, remarks, label TAG Deng.
Specifically, the present embodiment sets following media file scanning trigger mechanism：
1st, when into media application, or after media application is started, when being back to media play list main interface, need Scanning medium file, updates the media database of media play list and media application；
2nd, when generation SD card is inserted/removed, scanning medium file is needed, media play list is updated with media application Media database；
3rd, monitoring file presss from both sides the broadcast of content changing, and when such broadcast is received, startup file scanning, is that active request is swept The function of retouching provides extension.
Detect the media file condition of scanning trigger when, end of scan system medium file folder in media file and The media database of media application, obtains the media file information and media database in the terminal system media folder In media file information.
Wherein, as a kind of media file scan mode, following media file strobe utility can be adopted：
As shown in figure 4, by taking video file as an example, idiographic flow is as follows：
S11, scanning file；
S12, judgement are files, then into S13；Otherwise, return S11；
S13, determines whether video format file；If it is not, then entering S14；
S14, resolution file header；
S15, judges whether mimetype therein includes " video " field etc.；If so, then judge it is video file, it is no Then, judge it is not video file.
Specifically, after startup file scanning, the media folder on terminal inside/outside portion memorizer is traveled through one by one and is swept Retouch, filtering media files form, such as, whether file suffixes is the audio frequency and video form such as .mp4/.wmv.If not these forms, Then resolution file header, judges whether its mimetype includes " video/ " field etc..In scanning to after media file, by text Part parsing, decoding, preview show, it is possible thereby to improve the scan efficiency of media file.
For the scanning of the media database of media application, the media file recorded in main scanning multimedia database Key message, such as：Store path, file name, file size, file duration, label TAG, remarks, playing duration letter The information such as breath, file type, file state of activation.
After the media file information in media file information and media database in media folder is got, by two The media file information of person is compared, and judges whether the media file information in media folder changes, if sending out It is raw to change, then the media file information recorded in updating media database is corresponded to, while updating media play list.
Wherein, judge whether the media file information in media folder changes, in mainly judging media folder Whether media file newly-increased, deletion, modification operation etc. are had.
(as third-party application file manager enters to media file when media file in containing media folder changes Row renaming, deletion, content modification operation, and SD card removal etc.), trigger the multi-medium data update mechanism of media application.
The present embodiment is considered：When third-party application has carried out the operation such as renaming, modification, or SD card to media file Operation is removed/moved into, and the media database of picture library is not upgraded in time, now be there are problems that this：In data base Some record, it is impossible to corresponding media file is found by its store path, then judge this document do not exist.Further, since Picture library is the parameter informations such as media file additional maintenance classification TAG, collection, secret, and user is not intended to deletion these information.
Therefore, when being scanned, for non-existent record, deletion action is not performed, but updates the data storehouse, will This record is set to unactivated state, and updates media play list, does not show non-existent media file.
When starting scanning, start scanning thread, inquire about and cache the information of all records in picture library multimedia database：Deposit Whether storage path, file duration, the last modification time of file, file activate, for media folder under each media Fileinfo is contrasted.
Specifically, the media file in media file information and the media database in the media folder that will be obtained Information is compared, and (the present embodiment will weight whether the newly-increased of media file, deletion, modification in judging the media folder Name as the one kind in modification) operation.
Wherein, whether there are the newly-increased of media file, deletion in judging the media folder, modification operation can be using such as Under type：
If will be right in the filename of the media file in media folder, store path, file duration and media database The record answered is matched, and the record of matching is can not find in media database, then have media in judging the media folder File it is newly-increased；
If will be right in the filename of the media file in media folder, store path, file duration and media database The record answered is matched, and is recorded present in media database, and there is no corresponding media text in media folder Part information, the then deletion for having media file in judging the media folder；
If by the filename of the media file in media folder, store path, file duration and last modification time with In media database, corresponding record is matched, when filename, store path and file duration do not change and finally change Between change, then have the modification of media file in judging the media folder；
If by the filename of the media file in media folder, store path, file duration and last modification time with In media database, corresponding record is matched, and file duration does not change and filename and store path change, then There is the renaming of media file in judging the media folder.
Below to the modification outside the newly-increased of media file, deletion, renaming, the media number under the application scenarios of renaming It is described in detail according to synchronized update：
1st, for the application scenarios of newly-increased media file：
Two kinds of situations are moved into including newly-increased media file and SD card, wherein：
For newly-increased media file：One media file, this kind of feelings are increased newly under media folder by third-party application Under shape, the media file information in media file information in media folder and the media database is obtained by scanning Afterwards, by the filename of the media file in media folder, store path, file duration record corresponding with media database Matched, if the record of matching is can not find in media database, in judging the media folder, had media file It is newly-increased, then the relative recording of the store path of newly-increased media file, file duration is inserted in the media database.
For SD card is moved into：Due to not deleting to the respective record in data base, still can look for during scanning To the record of matching, therefore, the media that reappear are moved into because of SD card by comparing to detect to exist in media folder File, now then updates the corresponding record of the media database, and this record is set to state of activation.
2nd, for the application scenarios for deleting media file：
Two kinds of situations are removed including deletion media file and SD card, wherein：
For deletion media file：After third-party application (such as file manager) deletes certain media file, due to File is not present, when traveling through the All Files under media folder, does not have this record, in this case, then updates Corresponding record in the media database, and this record is set to into unactivated state；Wherein, the record of renewal at least include by The playing duration of deletion media file, remarks, label TAG information, it is to avoid after updating media database, cause media file The information such as playing duration, remarks, label TAG is deleted, and user next time is when playing the media again, it is impossible to record played when Between, cause Consumer's Experience poor.
For SD card is removed：To in media folder, there is media file to lose, class because SD card is removed by Determination It is similar to delete, as file is not present, then updates corresponding record in the media database, and this record is set to into un-activation State.
3rd, for the application scenarios of modification media file：
Third-party application changes certain media file, such as enters edlin to file, makes the modification time of file change, But store path (path) is not changed with file duration：This kind of situation, if being deposited in media folder by Determination In the media file of modification, then corresponding record in the media database is updated, and when this file in recording finally is changed Between be updated to the modification media file modification time, other information remains unchanged.
4th, for the application scenarios of renaming media file：
Including following two situations：
A. media file RNTO alternative document name：
Media file is still suffered from, but stores path changes, it is impossible to matched with having recorded in data base.By file when Length is matched with the carrying out of all records in data base, can be found an equal record of duration, now be updated media database, The path information of matching record is changed to into the routing information of existing file, other information keeps constant.(for extreme case, If finding the record of a plurality of duration matching, as original cannot be determined whether, now will be using this fileinfo as new note Record is inserted in data base).
B., after deleting certain file under media folder, a new file is copied into, and is named as original media file Name：Now the path information of file is matched with former record, further compares duration information, generally, new file The duration recorded in duration and media database is unequal, using this file-related information as new record, is inserted in data base. If there is the record of identical path information in data base, first this record deletion.(for extreme case, new copied files When path records original with data base with duration information are matched, the modification time for directly being updated the data storehouse respective record is The modification time of current file).
If that is, there is the media file of renaming by Determination in media folder, and media text The store path of part changes, then update corresponding record in the media database, and the store path of matching record is changed to work as The store path of front media file；Or, if there is document retaining name in detecting media folder but replace the matchmaker of original Body file, then be inserted into the relevant information of this media file as new record in the media database.
Media file in file by third-party application change, such as media file be renamed, delete, changing, with And SD card remove etc. when, real-time update media database, after the renewal for completing media database, real-time update media application Media play list, does not show non-existent media file, and to ensure the effectiveness of media play list, and real-time synchronization is Playing duration, remarks, label TAG information to media database, record media playing duration play position when playing again from Put continuation to play.
Thus, by the program, when the media file under media folder is changed, such as third-party application renaming, Delete, have modified media file, and SD card is moved out of, real-time synchronization media play list and media database only show Already present image, so as to ensure the integrity of media information, it is ensured that the effectiveness of image in media play list, improves and uses Experience at family.The overall flow block diagram of the present embodiment is referred to (by taking video file as an example) described in Fig. 5.
Further, the update module 203, is additionally operable to be spaced Preset Time, removes the media number with preset rules According to the label information of the media file of banked cache.
Specifically, as shown in fig. 6, can at regular intervals (such as 6 months), according to how long not being used by a user, The frequency that used, whether include：Playing duration, remarks, label TAG information, as rule, remove media database and delay The label information of the media file deposited.
Wherein, the frequency for being used is：It is total that the number of times that the media file is previously used/all recording files are previously used Number of times (using played media file, modification, mobile etc. is referred to).
The present embodiment passes through such scheme, according to the use habit of user, the media of periodic cleaning media data banked cache The label information of file, not only can improve the availability of media database memory space, and the cleaning by data, be use Family uses file provider just.
