Fig. 6 is the structured flowchart of cutting unit 54 in the file storage device according to the embodiment of the present invention, and as shown in Figure 6, this cutting unit 54 comprises acquisition subelement 62 and segmentation subelement 64.Below this cutting unit 54 is described.
Obtain subelement 62, for obtaining the key frame information of the video file in two or more filebufs, wherein, this key frame information comprises time stamp, side-play amount; Segmentation subelement 64, is connected to above-mentioned acquisition subelement 62, for splitting video file according to key frame information.
Fig. 7 is the structured flowchart of the recording apparatus in limited time according to the embodiment of the present invention, as shown in Figure 7, this device comprises with lower module: picture recording module 72 (with above-mentioned load module 24), File Pool module 74 (setting up module 22 with above-mentioned), document processing module 76 (with above-mentioned memory module 26), management of video module 78 (setting up module 22 with above-mentioned).Wherein this picture recording module 72, for gathering image, sound encoding; File Pool module 74 is for opening up filebuf and providing the read-write capability to multimedia file; Document processing module 76 is for splitting the multimedia file in File Pool, merge; Management of video module 78 provides the interface arranging video recording in limited time to user, such as, select RECORD mode, select the duration of video recording.
When recording a video, RECORD mode is set to Time Attack Mode by management of video module 78 and selects suitable duration by user, then user starts picture recording module 72 and starts video recording, the multi-medium data generated in video process writes certain file by File Pool module 74, the file that new video file covers automatically " excessively old ", user stops video recording immediately after photographing the scene wanted, document processing module 76 starts to split video file, merge, and up-to-date content is preserved into independent video file and is finally supplied to user.
Provide a kind of new RECORD mode in the above-described embodiments---Time Attack Mode, in such a mode, only record the content of nearest a period of time, length during this period of time can be specified as required by user, as 1 minute, 5 minutes, content before this time will be capped in shooting process, ensures that the file that video recording generates only comprises just incipient one section of scene thus, thus accomplishes that file size is controlled; Also can not miss the splendid contents of wanting to take simultaneously.
Fig. 8 is the process flow diagram of the display kinescope method according to the embodiment of the present invention, and as shown in Figure 8, the method comprises the steps:
Step S802, opens the recording function of mobile terminal.
Step S804, user also selected the duration needed by management of video model choice Time Attack Mode, as 1 minute, 5 minutes.
Step S806, starts picture recording module and starts video recording, automatically cover the content of " excessively old ", preserve up-to-date content in video process.This step can be realized by the following method: open up 2 filebuf A by File Pool module, B, the time of each buffer zone restriction video recording is the duration (as 1 minute) that user selects, Video data first exports to A buffer zone, when A buffer zone is full, starts to export to B buffer zone, can again export to A buffer zone when B buffer zone is slow, cover the content of original A buffer zone, change to B again when A is full, thus be used alternatingly.As shown in Figure 9, Fig. 9 stores schematic diagram according to the Video data of the embodiment of the present invention to this data Stored Procedure.
Step S808, user stops video recording immediately after photographing the scene wanted, and document processing module generates corresponding video file.Can adopt and realize this step with the following method: be if the content of a period of time is all kept at same buffer zone recently, then direct with corresponding buffer generation file; If distribution of content (has namely respectively deposited a part) on two buffer zones, then need two parts data to carry out splicing spanned file, in the middle of this, process has been mainly concerned with the generation of file header.Suppose that A buffer zone saves 00 ' 00 "-04 ' 59 " content during this period of time, B buffer zone saves 05 ' 00 "-06 ' 59 " content during this period of time, user stops video recording immediately, user is it is desirable that 02 ' 00 '-06 ' 59 " content during this period of time; for conventional video file form .mp4 (.3gp processing mode is similar); this process is as shown in Figure 10; Figure 10 is the video file processing flow chart according to the embodiment of the present invention, wherein for the form of video file for mp4 form is described.This process comprises the steps.
Step S1002, gets two file Key Frames List.
Step S1004, the time period that selection will be split, A gets 02 ' 00 "-04 ' 59 " this section, B gets 05 ' 00 "-06 ' 59 " this section, and obtain the key frame information in the corresponding time, comprise time stamp, side-play amount, due to multimedia coding non-linear behavior, key frame may time slightly deviation therewith, causes actual spanned file time length ratio requirement duration more bigger, because the impact of this point is minimum, can ignore Consumer's Experience impact.
Step S1006, regenerates moovbox (in mp4 file header most important information) and other mp4 file header content according to these key frame informations.
Step S1008, copies media data corresponding in two files, generates new mp4 file.
Obviously, those skilled in the art should be understood that, above-mentioned of the present invention each module or each step can realize with general calculation element, they can concentrate on single calculation element, or be distributed on network that multiple calculation element forms, alternatively, they can realize with the executable program code of calculation element, thus, they can be stored and be performed by calculation element in the storage device, and in some cases, step shown or described by can performing with the order be different from herein, or they are made into each integrated circuit modules respectively, or the multiple module in them or step are made into single integrated circuit module to realize.Like this, the present invention is not restricted to any specific hardware and software combination.
