Abstract
The invention discloses a double-index video circulating memory and quick retrieval method. The double-index video circulating memory and quick retrieval method comprises a video image storage method and a quick retrieval method, wherein the video image storage method comprises the following steps: judging whether the video data to be stored are I-frame data, conducting storage of the video data, checking the current storage path volume, meanwhile creating a video file and a video index file, and conducting multipath disk management to add the file path indexes to a database; the quick retrieval method comprises the following steps: calculating the name of the video file according to time through the database indexes, directly retrieving the storage position of the files in the database, accurately locating the deviation position of specific point in time in the files according to the file indexes, and directly obtaining the video data from the time point to play. The double-index video circulating memory and quick retrieval method disclosed by the invention has the benefits that the video is stored and retrieved through the double indexes to greatly shorten the retrieval time, increase the storage reliability and reduce the clip files.
Description
Technical field
The present invention relates to the image storage technique in computer realm, particularly relate to a kind of video circulation storage of duplicate key and the method for quick-searching.
Background technology
It is all that video file is had two kinds that the image of prior art stores generally, and a kind of is store according to the mode of fixed size, and a kind of is store according to the mode of set time.
Conventional video storage stores according to fixed size, generally file is divided into small documents and stores, can produce the file of flood tide like this.Carry out indexed search by database during retrieval, the longer time can be spent, particularly on embedded device.
If stored according to the set time, data volume is less so in a database, but during the concrete time point of locating file, can spend the longer time.
The storage of these two kinds of modes and retrieval mode, when video time is longer, all there is the situation that retrieval is slower, particularly in embedded device, retrieval rate can be slower.
Summary of the invention
Object of the present invention is overcoming the deficiencies in the prior art, the problem of comprehensive various storage and retrieval, propose a kind of video circulation storage of duplicate key and the method for quick-searching, can navigate to easily on the video storage time point of needs, during for user's quick-searching.
The object of the invention is to be achieved through the following technical solutions: a kind of video circulation of duplicate key stores and the method for quick-searching, and it comprises video image storing step and quick-searching step;
Described video image storage comprises following sub-step:
S101, obtain the video data that a frame needs to preserve, judge whether it is I frame data, if so, then carry out step S102, if not then end operation;
S102, carry out the storage of video data;
S103, check that current store path space is whether enough, if so, then create file, judge whether to be stored in current path or other path according to current store path, create video file and video index file, if not, then the oldest video file is deleted in circulation simultaneously;
S104, judge whether file puts in storage, if so, then end operation, if not, is then saved in database by file path index and relevant information, does the index of document location and relevant information;
Described quick-searching comprises following sub-step:
S201, database index, user, when retrieving the video of concrete time point, can go out the title of video file according to Time Calculation, then by the memory location of the direct retrieving files of database, just can navigate to file;
S201, pass through file index: the deviation post that accurately can be navigated to concrete time point in file by index file, just directly can obtain video data from this time point and play.
Following sub-step is also comprised in described step S102:
(1) current filename is generated computing time;
(2) judge whether to need to re-establish file according to filename, if so, then re-create new file, carry out step (3), if not, then directly store current video frame in current file;
(3) check whether there is this file, if there is no, then carry out step S103, if existed, then find the active position of file to continue stored video data.
The invention has the beneficial effects as follows: by duplicate key, carry out storage and the retrieval of video, greatly reduce the time of retrieval, and add the reliability of storage and reduce fragment file.By two secondary indexs of database index and file index, the video data of concrete time point in file can be found rapidly, and just directly can carry out decoding after sense data and play, there will not be the situation that mosaic or initial file can not be play.
Accompanying drawing explanation
Fig. 1 is the process flow diagram of video storage of the present invention;
Fig. 2 is the process flow diagram of the present invention according to the concrete file of timi requirement;
Fig. 3 is that the present invention navigates to the process flow diagram of data segment according to file index.
Embodiment
Below in conjunction with accompanying drawing, technical scheme of the present invention is described in further detail, but protection scope of the present invention is not limited to the following stated.

S102, carry out the storage of video data;
S103, check that current store path space is whether enough, if so, then create file, judge whether to be stored in current path or other path according to current store path, create video file and video index file, if not, then the oldest video file is deleted in circulation simultaneously;
S104, judge whether file puts in storage, if so, then end operation, if not, is then saved in database by file path index and relevant information, does the index of document location and relevant information;
Described quick-searching comprises following sub-step:
S201, as shown in Figure 2, database index, user, when retrieving the video of concrete time point, can go out the title of video file according to Time Calculation, then by the memory location of the direct retrieving files of database, just can navigate to file;
S201, as shown in Figure 3, pass through file index: the deviation post that accurately can be navigated to concrete time point in file by index file, just directly can obtain video data from this time point and play.
