Embodiment Construction

[0043] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0044] like figure 1 Shown is a flow chart of a method for recording a media file in an embodiment of the present invention. An operation record file is created in a non-volatile memory. The operation record file is independent of the media file, and the operation steps for recording the media file are recorded in the in the operation log file.

[0045] The method in this figure specifically includes, step 101, creating an operation record file independent of the ...

Abstract

The invention provides a restoration method and device for a media file recording anomaly. The method comprises the steps that during recording of media file recording operation, an operation recording file independent of a media file is created in a nonvolatile memory, and the operation step of media file recording is recorded in the operation recording file; and during media file restoration, the operation recording file is searched for in the nonvolatile memory, a data description part of the media file is restored according to content of the operation recording file, and the media file is restored according to the data description part and media data. Through the restoration method and device, the media file can be restored at extremely small storage cost under the condition of the media file recording anomaly.

Description

technical field [0001] The invention relates to the field of media file restoration, in particular to a method and device for repairing abnormal recording of media files. Background technique [0002] The structure of a media file, such as an MP4 file, can be divided into two parts, one part is media data, and the other part is data description. Since the data description part will continue to increase and modify with the continuous increase of the content of the media data part, the current implementation method for media files is to put the media data part in the front part of the media file in the file structure, and put the data description part It is temporarily stored in the memory, and the data in the memory is written to the latter part of the media file when the recording is stopped. In such an implementation, when an uncontrollable event such as abnormal exit of the program or abnormal power failure of the device occurs, the corresponding data description cannot b...
