Description

Technical Field

[0001] This application relates to the technical field of audio and video processing, and particularly to a continuous indexing method and device for completing missing video files in a video recording. Background Art

[0002] The network is not always reliable. When a network failure occurs and the audio and video data of the front-end device cannot be transmitted to the central storage management server, it will lead to the serious consequence of the loss of video recordings in the platform center. Similarly, when the central storage server goes offline, it will also cause the data of the front-end device not to be stored in the central storage server, resulting in discontinuous and incomplete central video recordings.

[0003] In the prior art, generally no processing is done for the above-mentioned situation of missing video recordings. Occasionally, corresponding solutions focus on completing the supplementary recording of the missing video data. For example, the missing video data is obtained from other terminals that may store video data, such as the device body storage or other storage servers, but the continuity problem between the supplementary recorded video file data and the original video file data is not considered. Or a database is used to record video file information, but additional operations or frequent requests are required to ensure the continuous playback of the video file and the supplementary recorded file, thereby affecting the operation experience.

The following description provides multiple embodiments of the present application. Different embodiments can be replaced or combined, so the present application can also be considered to include all possible combinations of the same and / or different embodiments described. Thus, if one embodiment includes features A, B, and C, and another embodiment includes features B and D, then the present application should also be considered to include embodiments containing one or more of all other possible combinations of A, B, C, and D, even though such embodiments may not be explicitly recited in the following content.

[0051] The following description provides examples and does not limit the scope, applicability, or examples set forth in the claims.

Various processes or components can be appropriately omitted, substituted, or added to each example. For example, the described methods can be performed in a different order than described, and various steps can be added, omitted, or combined. In addition, the features described in some examples can be combined into other examples.

[0052] Please refer to Figure 1 , Figure 1 which shows the overall flowchart of a continuous indexing method for missing video file completion provided by an embodiment of the present application.

[0053] As Figure 1 shown, the continuous indexing method for missing video file completion can at least include the following steps:

[0054] Step 101, obtain the nth audio-visual data based on an electronic device and convert the nth audio-visual data into the nth video file.

[0055] In an embodiment of the present application, the continuous indexing method for missing video file completion can be but is not limited to being applied to a storage server, which can establish connections with multiple electronic devices to obtain the audio-visual data sent by these multiple electronic devices. It can be understood that the storage server can complete the supplementary recording of video by establishing an index information table and achieve the continuity in time between reading the video file and the supplementary recording file.

[0056] Wherein, n is a positive integer greater than 1, only used for counting and identifying different video files.

[0057] Specifically, when the network and the video storage server are operating normally, the storage server continuously obtains audio-visual data from the front-end electronic devices and converts these audio-visual data into video files. The conversion method can be but is not limited to digital-to-analog conversion, etc.

[0058] Step 102: Extract at least four types of index information from the nth video file, and update the index information table according to the at least four types of index information of the nth video file.

[0059] Specifically, after the storage server converts the acquired audio-visual data into corresponding video files, these video files will be stored in the video file system of the server. The video file system can store, but is not limited to, the video files corresponding to the audio-visual data sent by one or more electronic devices. Then, for each stored video file, it is necessary to establish the index information corresponding to the video file. The necessary information included in the index information are: the lower file handle identification information, the upper file handle identification information, the time information, as well as the number, IP address, port, username, user access password, etc. of the electronic device to which the video belongs. Other non-necessary information such as file name, file length, file type, etc. can also be included. Among them, the file handle identification information is the unique identification information through which the corresponding file can be retrieved.

[0060] After that, the storage server will establish and update the index information table by realizing the connection between video files through the relevant information in the above index information, including but not limited to the lower file handle identification information, the upper file handle identification information, etc.

[0061] As an option in the embodiment of the present application, the at least four types of index information further include the current file handle identification information;

[0062] Extracting at least four types of index information from the nth video file and updating the index information table according to the at least four types of index information of the nth video file includes:

[0063] Based on the positions corresponding to the at least four types of index information of the (n - 1)th video file in the index information table, add the at least four types of index information of the nth video file to the index information table; wherein, the lower file handle identification information of the nth video file is empty, and the upper file handle identification information of the nth video file is the current file handle identification information of the (n - 1)th video file;

[0064] Update the lower file handle identification information of the (n - 1)th video file to the current file handle identification information of the nth video file.

[0065] Specifically, the upper file handle identification information and the lower file handle identification information of the first written file are both empty, and the remaining index information is filled according to the real information of the video file, and n files are written in sequence. Among them, if the (n - 1)-th file and the n-th file are time-continuous, then update the upper file handle identification information of the n-th file to the current file handle identification information of the (n - 1)-th file, and update the lower file handle identification information of the (n - 1)-th file to the current file handle identification information of the n-th file; if the (n - 1)-th file and the n-th file are not time-continuous, then the lower file handle identification information of the (n - 1)-th file and the upper file handle identification information of the n-th file are both empty. Thus, the video file index information table under the ideal process is established.

[0066] Here, the index information table as shown below can be referred to:

[0067]

[0068] In this index information table, the index information corresponding to the n-th file can but is not limited to include: file creation time, video start time, video end time, current video file handle, previous video file handle, next video file handle. Among them, file 2 is the next video file that is time-continuous with file 1. In the index information corresponding to file 2, the previous video file handle can be updated to the current video file handle in the index information corresponding to file 1, and the next video file handle in the index information corresponding to file 1 can be updated to the current video file handle in the index information corresponding to file 2. And so on, until the n-th file.

[0069] It can be understood that the embodiments of the present application show the correlation between video files through the handle identification information.

[0070] Step 103: In the updated index information table, respectively determine the m-th video file with the lower file handle identification information being empty and the (m + 1)-th video file with the upper file handle identification information being empty, and obtain the supplementary recording time period according to the time information of the m-th video file and the time information of the (m + 1)-th video file.

[0071] Among them, m is a positive integer, m is less than n, and is only used to identify different video files.

[0072] Specifically, to ensure the integrity of the recorded video in the video file system, it is necessary to periodically retrieve the video files. Through the video file index information table established in step 102, find the corresponding video files in the video file index information table where the file handle identification information is empty, and record them as the m-th video file. The subsequent consecutive video files of this video file do not exist, that is, the file handle identification information of the next video file of the m-th video file is empty. Continue to retrieve the video file system index information table backward, and find the corresponding video file where the upper file handle in the index information of the first video file is empty, and record it as the (m + 1)-th video file.

[0073] Thereafter, according to the relevant time information in the index information of the m-th and (m + 1)-th video files, including but not limited to the start time and end time of the video file, obtain the supplementary recording time period of the video file that needs to be supplemented.

[0074] As another option in the embodiment of the present application, the time information includes the video start time and the video end time;

[0075] Obtaining the supplementary recording time period according to the time information of the m-th video file and the time information of the (m + 1)-th video file includes:

[0076] Determine the supplementary recording time period according to the end time of the m-th video file and the start time of the (m + 1)-th video file.

[0077] Specifically, assume that the end time of the video file corresponding to the index information of the m-th video file is T1. At this time, the start time of the time period that needs to be supplemented is determined and defined as T1; assume that the start time of the video file corresponding to the index information of the (m + 1)-th video file is T2. At this time, the end time of the time period that needs to be supplemented is determined and defined as T2; thus far, the time period that needs to be supplemented is from T1 to T2.

[0078] Step 104: Determine the target electronic device according to the electronic device identification information of the m-th video file and the electronic device identification information of the (m + 1)-th video file, and generate a supplementary recording task request according to the video data of the target electronic device during the supplementary recording time period.

[0079] Specifically, referring to an embodiment as described above, assume that when the supplementary recording time period of the current video file is obtained as [T1, T2], the storage server can simultaneously obtain the identification information of the electronic device to which the video files missing in the current video file system belong, including the number, IP address, port, username, and user access password of the electronic device to which the video belongs. Thereafter, the storage server uses the above information to access the target electronic device and query the integrity of the video files stored on the electronic device during the supplementary recording time period, and updates the query result to the current supplementary recording task request. The target electronic device is the electronic device used to obtain the supplementary recording video data.

[0080] As another alternative of the embodiment of the present application, generating a supplementary recording task request according to the video data of the target electronic device during the supplementary recording time period includes:

[0081] When no video data corresponding to the supplementary recording time period is detected on the target electronic device, perform an update process on the supplementary recording time period, and generate a first supplementary recording task request according to the updated supplementary recording time period; wherein, in the updated supplementary recording time period, the video end time of the mth video file is the same as the video start time of the (m + 1)th video file;

[0082] When video data corresponding to the supplementary recording time period is detected on the target electronic device, generate a second supplementary recording task request according to the video data corresponding to the supplementary recording time period, and obtain the video data corresponding to the supplementary recording time period on the target electronic device based on the second supplementary recording task request;

[0083] When partial video data corresponding to the supplementary recording time period is detected on the target electronic device, generate a third supplementary recording task request according to the updated supplementary recording time period; wherein, the start time of the time period corresponding to the partial video data is greater than or equal to the video end time of the mth video file, and the end time of the time period corresponding to the partial video data is less than or equal to the video start time of the (m + 1)th video file;

[0084] Obtain partial video data on the target electronic device based on the third supplementary recording task request.

[0085] Specifically, referring to an embodiment as described above, assume that the supplementary recording time period of the current video file is [T1, T2]. When the query result shows that there is no video data during the supplementary recording time period stored on the target electronic device, the length of the video data that actually needs to be supplemented is 0 at this time. The storage server updates the supplementary recording time period in the original supplementary recording task request so that its supplementary recording end time T2 is the same as the supplementary recording start time T1. Thereafter, the storage server generates a first supplementary recording task request according to the updated supplementary recording time period. The first supplementary recording task request can be understood as a no-supplementary recording task request.

[0086] When the query result shows that there is complete video data during the supplementary recording period in the storage of the target electronic device, the original supplementary recording task request does not need to be updated at this time, and the original supplementary recording task request is the second supplementary recording task request. The storage server obtains the video data corresponding to the supplementary recording period on the target electronic device based on the second supplementary recording task request. Among them, the second supplementary recording task request can be understood as a supplementary recording task request with complete supplementary recording video data.

[0087] When the query result shows that there is partial video data during the supplementary recording period in the storage of the target electronic device. Assume that the start time of the video in the video query result at the target electronic device end is T3, the end time is T4, and T3 is greater than or equal to T1, and T4 is less than or equal to T2. At this time, the storage server updates the supplementary recording period in the original supplementary recording task request, making T1 consistent with T3 and T2 consistent with T4, generates a third supplementary recording task request, and obtains partial video data during the supplementary recording period on the target electronic device based on the third supplementary recording task request. Among them, the third supplementary recording task request can be understood as a supplementary recording task request with only partial supplementary recording video data.

[0088] As another option of the embodiment of the present application, after generating a supplementary recording task request according to the video data of the target electronic device during the supplementary recording period, it further includes:

[0089] When the supplementary recording task request is the first supplementary recording task request, in the index information table, update the lower file handle identification information of the m-th video file to the current file handle identification information of the (m + 1)-th video file, and update the upper file handle identification information of the (m + 1)-th video file to the current file handle identification information of the m-th video file;

[0090] When the supplementary recording task request is the second supplementary recording task request, convert the video data corresponding to the supplementary recording period into a video file; or

[0091] When the supplementary recording task request is the third supplementary recording task request, convert the partial video data into a video file;

[0092] Extract at least four types of index information from the video file, and update the index information table according to at least four types of index information of the video file.

[0093] Specifically, referring to an embodiment described above, assume that the supplementary recording period is [T1, T2], the specified period is [T3, T4], and T3 is greater than or equal to T1, and T4 is less than or equal to T2. The method for updating the video file system index information table is as follows:

[0094] When the supplementary recording task request is the first supplementary recording task request, no supplementary recording file is generated. At this time, update the "next file handle identification information" variable in the index information of the previous video file with continuous supplementary recording time period, so that it points to the handle of the next video file with continuous supplementary recording time period; secondly, update the "previous file handle identification information" variable in the index information of the next video file in the supplementary recording time period, so that it points to the handle of the previous video file with continuous supplementary recording time period. In this way, the video file system can continue to search for subsequent video files even at the discontinuous recording time of the video file index record;

[0095] When the supplementary recording task request is the second supplementary recording task request or the third supplementary recording task request, several supplementary recording files are generated. The newly generated several supplementary recording files establish new supplementary recording file index information according to the standard video file generation index method, as described in step 102; for the index information of the first supplementary recording video file and the last supplementary recording video file among the newly generated several supplementary recording files and the original video files with continuous supplementary recording time period, update the index information of the previous video file with continuous supplementary recording time period, and update the index information of the next video file with continuous supplementary recording time period. This can ensure that the video file system is continuous in time between the video file index information and the supplementary recording video file index information, and can continuously access the supplementary recording video file data after the video file data.

[0096] As another option of the embodiment of the present application, after generating a supplementary recording task request according to the video data of the target electronic device within the supplementary recording time period, it further includes:

[0097] When receiving a request for obtaining a video file, determine the video time period according to the request for obtaining the video file;

[0098] Based on the start time of the video time period, find the first video file in the updated index information table, and generate a target video file according to the first video file; wherein, the start time of the video time period is greater than or equal to the video start time of the first video file, and the start time of the video time period is less than the video end time of the first video file.

[0099] Specifically, record the video start time of the video file as T5, and with the help of the video file system index information table, find the video file or supplementary recording file record that satisfies that the start time of the video time period is greater than or equal to T5 and the start time of the video time period is less than T5. Since the time in the video file system is continuously increasing, there is only one video or supplementary recording file record that meets the conditions, and this video file is the first video file. And generate a target video file according to the first video file.

[0100] As another option of the embodiment of the present application, generating a target video file according to the first video file includes:

[0101] Determine a second video file based on the lower file handle identification information of the first video file;

[0102] When it is detected that the end time of the video recording period is greater than or equal to the start time of the second video file and the end time of the video recording period is less than the end time of the second video file, the first video file and the second video file are used as target video files.

[0103] Specifically, the end time of the recorded video file is T6. After retrieving the first video file, in sequence according to the video file index information recorded in the video file index information table, after reading the current video file, obtain the upper file handle identification information in the video file index information corresponding to the current video file, and locate the next video file or supplementary recorded video file pointed to by the lower file handle identification information. Determine whether the playback stop condition is satisfied in the video file index information: start time ≤ T6 < end time. If the condition is satisfied, this file is the last video file of the video recording period; if not, continuously repeat this retrieval process until the playback stop condition is satisfied.

[0104] Please refer to Figure 2 , Figure 2 which shows a schematic structural diagram of a continuous indexing device for missing complement of video files provided by an embodiment of the present application.

[0105] As Figure 2 shown, the continuous indexing device for missing complement of video files may at least include a first processing module 201, a second processing module 202, a third processing module 203, and a fourth processing module 204, where:

[0106] The first processing module 201 is configured to obtain the nth audio-video data based on an electronic device and convert the nth audio-video data into the nth video file; where n is a positive integer greater than 1;
