Description

Method and device for storing video recorded by mobile terminal

technical field

The present invention relates to the technical field of video recording by mobile terminals, in particular to a method for storing videos recorded by mobile terminals. The method is accomplished by establishing a functional module framework and controlling the computer system by computer program instructions.

Background technique

Today's mobile terminals are basically equipped with a video recording function (recording video). After recording a video, the mobile terminal will store the recorded video file in the memory (such as an SD card), and store information such as the length and size of the video in the database. In order to facilitate the user to view and manage the video information in the mobile terminal.

The process of storing the recorded video files in the memory is mainly realized by the file system, which is a software mechanism responsible for managing and storing file information in the operating system of the mobile terminal; that is, the method of organizing files on the disk, mainly It is used to organize and allocate file memory space, and is responsible for creating files for users, storing, reading, modifying, and dumping files, etc. In different operating systems, the structure of the file system is also different, and due to the structure of the file system itself, the size of the file that can be stored at one time is limited, that is to say, the size of the data that the mobile terminal can store at one time is Limited (for example, some mobile terminals using the Android system based on the Ext2 file system can only store files no more than 2G in size). This means that when using a mobile terminal to record video, the size of the video that can only be recorded at one time cannot exceed 2G. If the size of the recorded video reaches 2G, the system will save the 2G video file first, and then save it again. Re-record and save as a new file.

However, with the advancement of equipment processing technology and the improvement of video recording methods, the video recording function of mobile devices has gradually moved towards high-definition, for example, data formats such as 480P, 720P and 1080P have been adopted. And high-definition will inevitably make the data volume of video files larger. This also causes the size of the recorded video to easily exceed the maximum amount of data that the file system of the mobile terminal can support, resulting in the video of the same subject being divided into multiple video clips, which will be generated separately in the database Video information, resulting in file confusion and difficult management when users view the captured video later. For example: a user uses a mobile terminal with an Android system based on the Ext2 file system to shoot a meeting and a concert (that is, the theme of the meeting and the theme of the concert). The shooting process of each theme will be divided into 5 times for shooting, each time a 2G video file will be stored, and each video file will generate a video information. That is to say, there are 10 video clips in the database after shooting the meeting and concert. These 10 video clips belong to two different themes. If users want to classify or extract operations, they need to click and view one by one The two are distinguished, so as to know the length and size of the videos taken by the two subjects respectively.

Contents of the invention

The purpose of the present invention is to avoid the disadvantages of the above-mentioned prior art and provide a mobile terminal recording video storage method that can effectively avoid the problem of messy management caused by the same video subject having multiple video clips.

The object of the present invention is achieved through the following technical solutions:

Provided is a method for saving video recorded by a mobile terminal, including:

Save preparation step: detect the selection command input by the user and judge whether to merge the currently recorded video with the previous recorded video according to the command, and if so, enter the merge and save step;

Merging and saving steps: When saving the video, merge the video information of the currently recorded video with the video information of the previous recorded video to become virtual video information, and at the same time associate the saved file of the currently recorded video with the saved file of the previous recorded video so that both can be played continuously automatically;

Displaying step: read the virtual video information in the database to display the virtual video when displaying the video information.

Wherein, the merging and saving step includes a data merging step: superimposing the data in the video information of the currently recorded video with the data of the attribute data of the previous recorded video recorded in the database to generate virtual video attribute data, and the data recorded in the database The attribute data of the previously recorded video is replaced with the virtual video attribute data so that the video information of the previously recorded video recorded in the database becomes virtual video information.

Wherein, the merging and saving step includes an automatic association step: using the saved file name of the previously recorded video as part of the saved file name of the currently recorded video; the display step includes a playing step: according to the saved file name of the video Relevance autoplays videos. the

Wherein, the preservation preparation step includes an information acquisition step: obtaining the preservation file name of the previously recorded video and judging whether the previous recording video still exists, and if so, entering the preservation preparation step.

Wherein, the information acquisition step includes an information configuration step: adding an information record item for recording the saved file name and the storage path of the video recorded last time in the configuration file of the video recorder, and obtaining the content of the information record item when starting the video recorder, And check whether the video recorded last time exists according to the saved path of the record.

Beneficial effects of the present invention: the present invention judges whether the current video has the same theme as the previous video according to the user's selection, and then merges the videos of the same theme. Video information (that is, a collection of information about multiple video clips on the same topic), if you click to watch, you will watch the first video of the topic first, and then the videos of the topic will be automatically played sequentially due to the association between the video clips. It is the same as watching the same video; this effectively avoids the problem of messy management caused by having multiple video clips for the same video topic.

Detailed ways

The present invention is further described in conjunction with the following examples.

A specific embodiment of a method for prompting in time that a mobile smart device is damaged due to a fall of the present invention includes:

Step A: Obtain the save file name and save path of the previously recorded video when starting the video recorder. If the acquisition fails, proceed to step E; if the acquisition succeeds, read the save file of the previously recorded video according to the save path, such as If the reading is successful, it is judged that the saved file of the video recorded last time exists, and enters step B; if the reading fails, then enters step E;

Step B: Display a dialog box to ask the user whether the current video and the previous one have the same theme. If the user enters an instruction and selects yes, then enters step C. If the user enters an instruction and selects no, then enters step E;

Step C: superimpose the data in the video information of the currently recorded video with the attribute data of the previous recorded video recorded in the database to generate virtual video attribute data, and replace the attribute data of the previously recorded video recorded in the database It is virtual video attribute data so that the video information of the previous recorded video recorded in the database becomes virtual video information; at the same time, the saved file name of the previously recorded video is used as part of the saved file name of the currently recorded video;

Step C is exemplified: if the video information of the previous video in the database includes two information of video length and video size, then when the current video is kept, the video length of the current video is compared with the video length of the previous video recorded in the database. Add to get the virtual video length, add the video size of the current video and the video size of the previous video recorded in the database to get the virtual video size, and then use the virtual video length and virtual video size to replace the video information recorded in the previous video Video length and video size, so that the video information of the previous video in the database is replaced with virtual video information. At the same time, assuming that the previous video is named XXX.MP4, then the current video is named XXX_1.MP4, so During subsequent playback, the player will automatically recognize it for continuous playback.

Step D: When displaying video information, read the virtual video information in the database (that is, merge the video information of the current video and the video information of the previous video) to display the virtual video. When the user clicks to play, it will be based on the relevance of the saved file name of the video Autoplay video.

Step E: According to the prior art, save the current video as a new video, and record the video information in the database.

It should be noted that although the above embodiment only describes the merging of two segments, when the same main body has multiple segments, each segment can be merged with the previous video one by one, so as to finally form a virtual video. For example, in the case of three video clips, when shooting the second segment, merge the second segment with the first segment to form the first virtual video, and when shooting the fourth segment, combine the third segment and the first virtual video to form the final virtual video .

Through the above method, when viewing the captured video after merging, the user will only see the virtual video information (that is, the information collection of multiple video clips of the same topic), and the first video of the topic will be watched first when clicking to watch , and then the video of the topic shot will be automatically played sequentially due to the association between the video clips, as if watching in the same video; this effectively avoids the problem of messy management caused by the same video topic having multiple video clips .

In the method given in this paper, all or part of the steps can be completed by establishing a functional module framework and controlling the computer system by computer program instructions. These computer program instructions are stored on a computer readable storage medium.

Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting the protection scope of the present invention, although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand , the technical solution of the present invention may be modified or equivalently replaced without departing from the spirit and scope of the technical solution of the present invention.
