Description

File processing method and device, video playing method and device and electronic device

Technical Field

The invention relates to the field of computers, in particular to a file processing method and device, a video playing method and device and an electronic device.

Background

In the field of video surveillance, particularly in the security industry, video data is collected in real time, such as video files. The acquired data has continuity on a time axis, the continuous data can grow infinitely along with time, the data is called as 'streaming data', the streaming data is segmented according to time intervals, for example, the data is segmented into large files at intervals of 1 hour, and each large file is also continuous on the time axis.

The streaming data file is continuous in default in scenes such as video query, video playback, video forwarding and the like, and can be switched into different files in default if interruption occurs, so that the file can be fed back to an interrupted time slice of an application layer through attributes of the file, and the application layer can query and playback data conveniently.

For a storage system, the differentiated service types may be divided into large files and small files according to the sizes of the files. In the case of streaming data files, large files are used because of the long slicing intervals. In the business of writing large files, if large files are written and a large number of large files with small capacity are written, this is called file fragmentation, and the pressure of writing and reading is increased for the system.

For a storage system, when a scene of a small file service is processed, the small files are organized and aggregated into a large file in a certain way, and a common solution is to package an external client or perform object-level integration inside the storage system, and finally the large file is still stored in the system. For the above-mentioned "fragmented file", it needs to be converted in a special form at the client layer of the storage system to generate a large file that is good for the storage system and is synthesized in a manner similar in business performance, which is called file aggregation, that is, corresponding to multiple video data segments in the same file, the time in each data segment is incremental but discontinuous.

At present, in a technical scheme of 'file aggregation', a video file is generated every 1 hour in a video streaming data recording scene, and each video file is continuous in time under a normal condition without problems. But the file a is closed immediately when the recording is interrupted due to network jitter or other reasons, and the time span of the file a may be very small. And after the video recording is recovered, storing the file B into a new file B, and interrupting the time of the file A and the time of the file B.

If the number of files is increased rapidly when the interruption frequency is high, the data volume of each file is small; the process of creating a large file, writing data and closing the file is executed at high frequency, and finally, massive small files occupying a large file handle are generated; the number of the handles of the large files is rapidly burst, so that the system capacity reaches the limit and the writing can not be continued.

In view of the above problems, no effective solution has been proposed.

It should be noted that the solution of the present embodiment may include, but is not limited to, the following applications: when recording, the video file is frequently switched due to video interruption triggered by network jitter or abnormal access of a terminal to a PAAS (platform-as-a-service) platform, namely, a service storage service. This scenario generates a large number of fragmented files and reaches the file count limit, which is a significant hazard to the availability and performance of the system. Based on the original system index mode, the broken files are gathered into large files by introducing the technology of recording the 'hole information', so that the pressure on the system is reduced, and the performance is improved.

According to the embodiment provided by the application, a first recording file is obtained in the target video recording process, wherein the first recording file is obtained by recording the target video in a first time period; acquiring a second recording file, wherein the second recording file is a recording file obtained by recording a target video in a second time period; combining the first recording file and the second recording file into a first target recording file under the condition that a third time period exists between the first time period and the second time period and the sum of the first time period, the second time period and the third time period meets a preset time period, wherein the third time period is a time period for interrupting recording of a target video; the method comprises the steps of writing a first target recording file and corresponding first related information into the first target file, wherein the first related information is used for describing the first target recording file, and achieving the purpose of combining the first recording file and a second recording file according to interruption information, so that the broken files are integrated into a large file, the file storage capacity of a system is optimized, the technical effect of breaking through the storage capacity limit of the system under the mass broken files is achieved, and the technical problem that in the prior art, the limit pressure on a file system is caused by the fact that the handle of the large file is increased rapidly due to frequent interruption in the video recording process is solved.

Optionally, in this embodiment, after merging the first recording file and the second recording file into a target recording file and writing the target recording file into the first target file, the method may further include: acquiring a third recording file, wherein the third recording file is a recording file obtained by recording a target video in a third time period, and the third time period and the second time period are continuous time periods; acquiring a fourth recording file, wherein the fourth recording file is a recording file obtained by recording a target video in a fourth time period; combining a third recording file and a fourth recording file into a third target recording file under the condition that a fifth time period exists between the third time period and the fourth time period and the sum of the third time period, the fourth time period and the fifth time period meets a preset time period, wherein the fifth time period is a time period for which the recording of the target video is interrupted;

and writing the third target recording file and corresponding second related information into a second target file, wherein the second related information is used for describing the second target recording file.

Optionally, in this embodiment, after writing the second target recording file and the corresponding second related information into the second target file, the method may further include: under the condition that N target recording files exist in the target video recording process, writing the Nth target recording file and corresponding Nth related information into a third target file, wherein the Nth related information is used for describing the Nth target recording file, and N is a natural number which is more than or equal to 2; and the Nth hole information in the Nth related information comprises the hole information of the (N-1) th target recording file and the hole information of the Nth target recording file.

It should be noted that the original system introduced the concept of indexing for instant storage, instant playing and fast playback of video.

Wherein, the secondary index: the positions of N frames are stored, the secondary index record is the index information of the data frame between two I frames and the address of the previous primary index, and the secondary index is recorded once every 2 seconds.

And the primary index refers to complete index information of the current video, a primary index is generated after 30 secondary indexes according to the frequency of the indexes, each primary index knows the positions of all I frames before the current position in the file, and the primary index is recorded once at intervals of 60 s.

Indexing of the file tail: the index information of all I frames is generated when the video file is closed, and the I frame index information of the tail of the file is directly read to realize quick playback without viewing the primary index and the secondary index recorded in the front after the file is closed.

As shown in fig. 3, the index is schematic. After each file closing, an "index" and "file information" of the file tail are generated.

As shown in fig. 4, in the embodiment provided by the present application, based on the original system, a "hole" record, that is, "hole information" (corresponding to interrupt information) is introduced in a scene of video jitter, and the using method is specifically as follows.

Hole information is (N +1) th write start time — nth write end time.

The recording method of each information in this scheme is explained in detail below.

1. And generating a hollow hole.

The first written data is written into the index and the file information of the file tail when the video recording is interrupted (equivalent to the first recorded file in the first time period), and then the file is closed.

When writing data for the second time (corresponding to the second recording file in the second time period), the abnormality is recognized first, and then the file is opened again to continue additional writing data.

In the process of writing data for the second time, recording the hole information of the current writing and the last writing before the first-level index; if the interval does not reach the first-level index recording frequency and requests to close the file, the hole information is recorded once before the index at the tail of the file. So that there is at least one hole information every 60s (primary index recording frequency).

2. And (4) accumulating the holes.

It should be noted that the following hole information is the combination of the previous hole and the current hole, and the specific accumulation mode is as follows: the nth hole (N-1) th hole + this hole.

When the video is played back, the nearest hole is read to obtain all the previous hole information, and the fast playback is carried out.

3. And accumulating the indexes.

Wherein, for the tail index (corresponding to the first tail index information or the second tail index information), the tail index of the previous data writing is accumulated.

After the streaming file is stored in the above manner, the logic of the video query is changed, and the method is mainly divided into the following scenes:

scene 1: the file is closed normally.

It should be noted that, in a normally closed scene, the tail of the recording file is composed of "hole information + index + file information".

In this embodiment, all the contents of the video can still be acquired through "index"; the time interval can be quickly obtained by the "hole" for video playback.

Scene 2: and storing and putting the video.

Step 1.1, the last data block is a primary index;

1.1.1, find the secondary index within the range, then perform step 1.2.

Step 1.2, the last data block is a secondary index;

1.2.1, finding the last one-level index in the data block results in: the hole information can be found;

1.2.1, finding the last one-level index in the data block results in: there is no hole information.

Step 1.3, the last data block is video information;

1.3.1, following the existing procedure: loading 4M data content, and executing the step 1.2 after finding the secondary index;

and step 1.4, directly acquiring the hole information, wherein the last data block is the hole information.

Scene 3: the file is closed abnormally.

It should be noted that the video query after abnormal shutdown is consistent with the logic of scene 2, and is not described again.

And 1.5, carrying out video restoration flow after abnormal shutdown.

It should be noted that, in the original flow, the video needs to be traversed to be repaired.

In this embodiment, the video restoration implementation flow after abnormal shutdown is as follows.

The traversal process finds the 'hole information', records the 'hole information' in the memory, and replaces the old hole information with the new hole information. After traversing to the tail of the file, the recorded 'hole information + file tail index + file information' is stored in the repaired file.

According to the embodiment provided by the application, fragmented files are connected into a large file in a mode of recording the 'hole information', so that the overload use of a large file handle is greatly reduced, and the usability of the system is increased. When the video is played back, the distribution of the video in a certain whole time (such as 1 hour) can be obtained by reading one file, and meanwhile, high-efficiency reading and loading capabilities are provided for video query.

The processing mode of the embodiment provided by the application under the video jitter scene is better compatible with the original system, the mode of inheriting the primary index, the secondary index and the file tail index of the original system is used for recording and loading the 'hole information' in the process, the 'hole information' is integrated into the video code stream file, no additional file is required to be maintained, and the complexity of the system is reduced; the method is also compatible with the process of video recovery scene, only needs to logically identify the 'hole information', and ensures that the system can be continuously and stably under the abnormal scene.

It should also be noted that the solution of the present embodiment has the following benefits:

1. in a video jitter scene, the broken files are integrated into a large file by the technology of recording the 'hole information', the file storage capacity of the system is optimized, and the storage capacity limit of the system under the mass broken files is broken through.

2. When the video jitter causes stream interruption, the mark is 'hole information', the information is composed of StartTime (interruption starting time) and EndTime (interruption ending time), and the recording is accumulated every time the jitter is interrupted.

2. The 'hole information' is a mark of interruption information when the stream is interrupted due to video jitter, and is composed of StartTime (interruption starting time) and EndTime (interruption ending time), and the mark is continuously accumulated and embedded into a video code stream file in a 'special frame' form, so that the aim of quickly identifying the video time segment information when the video file is read is fulfilled.

3. The 'hole information' can be recorded in front of the 'primary index' of the original system, the content is the repetition of the 'hole information' accumulated in front of the 'hole information', the aim of 'storing and putting immediately' is achieved, and meanwhile, the 'hole information' can be rapidly read when the video is abnormally interrupted and the playback is interrupted.

4. When the file is closed, one copy of hole information is recorded at the tail of the original system file, and the content is the repetition of the hole information accumulated in front of the file, so that the aim of quickly obtaining the time distribution of the whole video is achieved during video query and playback.

5. After the video file is abnormally closed, the method is consistent with the method for repairing the video index, and the cavity information is filled up by scanning the file, so that the embodiment provided by the application basically has no influence on the repair of the video index of the original system, and the stability of the system is ensured.
