FIG. 7 is a structural block diagram of a time-limited recording apparatus according to an embodiment of the present invention. As shown in FIG. 7, the apparatus includes the following modules: a recording module 72 (same as the above input module 24) and a file pool module 74 (same as the above-mentioned establishing module 22). The file processing module 76 (same as the above storage module 26) and the recording management module 78 (same as the above-described building module 22). The recording module 72 is configured to collect images, sounds, and encodes; the file pool module 74 is configured to open a file buffer and provide a function for reading and writing multimedia files; and the file processing module 76 is configured to perform multimedia files in the file pool. Split and merge; the video management module 78 provides the user with an interface for setting time-limited recording, such as selecting a recording mode and selecting the duration of the recording.

During recording, the user sets the recording mode to the time-limited mode through the recording management module 78 and selects an appropriate duration, and then the user starts the recording module 72 to start recording, and the multimedia data generated during the recording process is written into a file through the file pool module 74. The new video file automatically overwrites the "old" file, and the user stops recording after capturing the desired scene. The file processing module 76 starts splitting and merging the video files, and saves the latest content as a separate video file. And ultimately to the user.

In the above embodiment, a new recording mode, a time-limited mode, in which only the most recent content is recorded, the length of the time can be specified by the user as needed, such as 1 minute, 5 minutes. The content before this time will be overwritten during the shooting process, thus ensuring that the file generated by the recording only contains a scene that has just appeared, so that the file size can be controlled; and the wonderful content that you want to shoot is not missed.

FIG. 8 is a flowchart of a display recording method according to an embodiment of the present invention. As shown in FIG. 8, the method includes the following steps:

Step S802, the recording function of the mobile terminal is turned on.

In step S804, the user selects the time-limited mode through the recording management module and selects the required duration, such as 1 minute and 5 minutes.

In step S806, the recording module is started to start recording, and the “old” content is automatically overwritten during the recording process, and the latest content is saved. This step can be implemented by the following method: opening two file buffers A and B through the file pool module, each buffer restricts the recording time to the length selected by the user (for example, 1 minute), and the recorded data is first output to the A buffer. When the A buffer is full, it starts to output to the B buffer. When the B buffer is slow, it will output to the A buffer again, overwriting the contents of the original A buffer, and then changing to B when A is full, thus alternately used. The data storage process is shown in FIG. 9. FIG. 9 is a schematic diagram of recording data storage according to an embodiment of the present invention.

In step S808, the user stops recording after capturing the desired scene, and the file processing module generates a corresponding video file. You can use the following method to achieve this step: if the content of the most recent time is saved in the same buffer, you can directly generate the file with the corresponding buffer; if the content is distributed in two buffers (that is, each part is saved), Then two pieces of data need to be spliced to generate a file, and the process mainly involves the generation of a file header. Suppose the A buffer saves the time of 00'00"-04'59", the B buffer saves the time of 05'00"-06'59", and then the user stops recording. The user needs 02' 00 '-06'59" This time content, taking the common video file format .mp4 as an example (.3gp processing is similar), this process is shown in FIG. 10, FIG. 10 is a video file processing flow according to an embodiment of the present invention. The figure is illustrated by taking the format of the video file as the mp4 format as an example. The process includes the following steps.

In step S1002, two file key frame lists are obtained.

Step S1004, selecting a time period to be divided, A takes 02'00"-04'59", B takes 05'00"-06'59", and obtains key frame information in the corresponding time, including time Poke, offset, due to the nonlinear characteristics of multimedia coding, the key frame may be slightly deviated from this time, resulting in the actual generated file length is slightly larger than the required time, because the impact of this point is minimal, the impact on the user experience can be ignored.

In step S1006, the moov box (the most important information in the mp4 file header) and other mp4 file header contents are regenerated according to the key frame information.

In step S1008, the corresponding media data in the two files is copied, and a new mp4 file is generated.

It will be apparent to those skilled in the art that the various modules or steps of the present invention described above can be implemented by a general-purpose computing device that can be centralized on a single computing device or distributed across a network of multiple computing devices. Alternatively, they may be implemented by program code executable by the computing device such that they may be stored in the storage device by the computing device and, in some cases, may be different from the order herein.
