Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be obtained by a person skilled in the art without making any creative effort based on the embodiments in the present invention, belong to the protection scope of the present invention.
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
The information processing scheme provided by the invention can be applied to recordable products, such as law enforcement recorder applications of related terminals, and is used for repairing package format files when the video recording is abnormally interrupted, and the MP4 file is used for the following description of the present application, and it can be understood that other package formats (any file formats including following typ box data block, free box data block, mdat box data block and moov box data block), which are not listed, are also within the protection scope of the present application.
To facilitate understanding of the present invention, the following description first deals with the structure of an MP4 file:
the structure of the MP4 file includes ftypbox (file type and compatibility) data blocks, free box data blocks, mdat box (media data container) data blocks, and moov box data blocks.
The ftyp box data block is used for storing version information of the file; the content in the free box data block is irrelevant, and can be ignored, and after being added or deleted, the content will not affect the playing, and generally speaking, the content is empty; the mdatbox data block is used for storing audio/video encoded frame data, and is internally composed of an audio frame sequence (i.e. audio frame sequence) or a video frame sequence (i.e. video frame sequence), and the frame sequence (also referred to as Chunk in the industry) is composed of a set of encoded audio frame data or a set of encoded video frame data; the moov box data block records the audio and video coded metadata, i.e. video track summary information.
At present, the order of storing the data blocks in the file in the MP4 file format standard is not required. The present invention requires that the free box data block and the mdat box data block be placed adjacent to each other, and that the free box data block be located before the mdat box data block. For details, see the following example disclosure.
In summary, from the definition of the MP4 file structure, the irrelevance of the content of the free box data block can be known, so the present invention proposes to store the media parameter information required for repairing the damage of the late moov box data block generated during the video recording process into the free box data block in real time, and read the content in the free box data block during the repair, that is, the missing moov box data block can be reconstructed by using the information, thereby achieving the purpose of repairing the MP4 file.
See the method flow diagram shown in fig. 1. The embodiment of the invention provides an information processing method, which comprises the following steps:
s10, responding to a packaging instruction of the media format file obtained by video recording, creating a first data block, and writing the version information of the media format file into the first data block.
In an embodiment of the present invention, the media format file is encoded frame data, and the frame data includes at least one of audio frame data and video frame data.
In addition, in the embodiment of the present invention, a first data block is created, that is, an ftyp box data block is created, and version information of the media format file, such as the MP4_ V1 version, is written in the ftyp box data block.
And S20, creating a second data block adjacent to the first data block, and writing the coding information of the media format file into the second data block.
Referring to the MP4 file structure shown in fig. 2, in the embodiment of the present invention, a second data block, i.e., a free box data block, is disposed adjacent to an ftyp box data block, and a certain storage space is allocated, and coding information is written into the free box data block, where the coding information includes audio parameters and video parameters, the audio parameters include an audio coding type, a sampling rate, and a channel, and the video parameters include a video coding type, a resolution, and a frame rate.
And S30, creating a third data block adjacent to the second data block, and sequentially writing frame data of the media format file into the third data block in a frame sequence mode, wherein one frame sequence is composed of a plurality of frame data of the same type and adjacent time.
With continued reference to the MP4 file structure shown in fig. 2, in the embodiment of the present invention, the third data block, i.e., the mdat box data block, is disposed adjacent to the free box data block, and the frame data in the memory is written into the mdat box data block in the form of a frame sequence, where one frame sequence may be an audio frame sequence or a video frame sequence.
It should be noted that, the arrangement of the audio frame sequence and the video frame sequence in the plurality of frame sequences is not limited in the embodiments of the present invention. In practical applications, the memory may start an audio frame sequence and a video frame sequence simultaneously, and when a plurality of audio frame data in the memory meet a corresponding frame sequence end condition, the plurality of audio frame data are combined into an audio frame sequence, and correspondingly, when a plurality of video frame data in the memory meet a corresponding frame sequence end condition, the plurality of video frame data are combined into a video frame sequence. The above-described frame sequence end condition may be set for the number of frames, and may also be set for the key frame.
And S40, monitoring the frame sequence currently in the writing ending state in the third data block, and writing the frame parameter information of the frame sequence currently in the ending state into the second data block, wherein the coding information and the frame parameter information written into the second data block are media parameter information for realizing recombination.
See fig. 3 for an example of a free box data block. When the frame sequence Chunk1 in the mdat box data block finishes writing and Chunk2 starts writing, the frame parameter information related to Chunk1 is written into the free box data block. Taking the Chunk1 frame parameter information as an example, "2-byte length size" is the data amount of the frame parameter information in the free box data block, "4-byte Chunk offset" is the offset of the beginning position of Chunk1 in the mdat box data block, "4-byte frame size" is the data amount of the single frame data in Chunk1 in the mdat box data block, and "4-byte frame timestamp" is the timestamp of the single frame data in Chunk 1.
The audio parameters, video parameters, and frame parameter information of multiple chunks written in the free box data block are media parameter information necessary for reconstructing the moov box data block. However, how to reconstruct the moov box data block based on the information written in the free box data block may be implemented in any manner, which is not limited in the present invention.
In other embodiments, since the storage space of the free box data block is reserved, there may be a problem of insufficient storage space during the video recording process, and to solve this problem, after the step S40 "monitoring the frame sequence currently in the write-end state in the third data block" is executed, the following steps may also be executed:
acquiring the size of a free storage space of a second data block; judging whether the size of the free storage space is larger than the size of the frame parameter of the frame sequence in the ending state at present; if yes, step S40 "write the frame parameter information of the frame sequence currently in the end state into the second data block" is executed.
Continuing with the free box data block example shown in FIG. 3. In the embodiment of the invention, a certain storage space is allocated to the free box data block in advance, so when the frame sequence Chunk3 in the mdat box data block finishes writing and Chunk4 starts writing, whether the size of the unoccupied part of the storage space, namely the size of the free storage space, is larger than or equal to the size (data volume) of the Chunk3 frame parameter information is judged by acquiring the size of the free storage space in real time, and if so, the Chunk3 frame parameter information can be written into the free box data block, otherwise, the Chunk3 frame parameter information cannot be written into the free box data block.
On this basis, in order to deal with the situation that the free storage space of the free box data block is not enough to write the Chunk3 frame parameter information, the embodiment of the invention further comprises the following steps:
if not, moving the frame sequence positioned at the starting position in the third data block to the tail position of the third data block; updating the initial position of the third data block to increase the free storage space of the second data block, and returning to execute the judgment whether the size of the free storage space is larger than the size of the frame parameter of the frame sequence in the ending state currently; frame parameter information in the second data block of the frame sequence moved to the end position of the third data block is updated.
See fig. 4 for a schematic diagram of expansion of the storage space of the free box data block. In the present invention, the free box data block and the mdat box data block are adjacently arranged, and the free box data block is before the mdat box data block, so that the content of the frame sequence Chunk near the start position of the mdat box data block (i.e. the Chunk located at the start position in the mdat box data block) can be moved to the end of the mdat box data block by utilizing the independence of the Chunk sequence in the mdat box data block, and the frame sequence Chunk1 in fig. 4 is moved to the back of the frame sequence Chunk 3.
Further, the start bit of the mdat box data block is changed, the storage space of the free box data block is expanded, and the offset of the shifted frame sequence Chunk recorded in the free box data block is updated. In order to free enough storage space for the free box data blocks for recording the corruption repair information.
In some other embodiments, for a scene with abnormal recording, the embodiment of the present invention may further include the following steps: and responding to the video abnormal instruction, and recombining a fourth data block containing audio and video track summary information based on the coding information and the frame parameter information written in the second data block.
It should be noted that how to reconstruct the moov box data block based on the information written in the free box data block may be implemented in any manner, and the present invention is not limited to this.
For a scene where the video recording is normally ended, the embodiment of the present invention may further include the following steps:
responding to a normal video recording ending instruction, creating a fourth data block containing audio and video track summary information, and writing the audio and video track summary information of the media format file into the fourth data block; and erasing the coding information and the frame parameter information written in the second data block.
In the embodiment of the invention, when the video recording is normally finished, a complete moov box data block can be created into an MP4 file, the moov box data block is written into audio and video track summary information, the audio track summary information comprises coding information and frame parameter information of a frame sequence, and other information, and at the moment, the information written into the free box data block can be erased.

In addition, the method for storing the private data of the MP4 format file is provided by skillfully arranging the internal structure of the MP4 file and the regular moving Chunk file structure. Of course, the method is also suitable for the packaging format similar to the Mp4 file, such as the Mov format, i.e. the invention is also suitable for storing other customized private data.
