Description

Technical Field

[0001] This application relates to the field of cloud recording technology for streaming media, and in particular to a method, apparatus, streaming media server, storage medium, and computer program product for storing video files. Background Technology

[0002] Video surveillance data can effectively help users review the scene and identify problems. Streaming media cloud recording is one method for generating video surveillance data. This method receives media stream data, records it into video files, and then uploads the video files to cloud storage, meeting the long-term storage needs of massive amounts of video data. Because it involves the recording and storage of user data, the stability and reliability of streaming media cloud recording are very important and need to be guaranteed from multiple aspects.

[0003] One problem is that during the process of uploading video files to cloud storage, various factors such as generating too many video files, fluctuations in cloud storage performance, and limited network bandwidth can cause video files to fail to be uploaded to cloud storage in a timely manner, becoming stuck in the memory of the streaming media server. As a result, the memory usage continues to increase, which may eventually cause the streaming media service to crash and the data in memory to be lost directly. Summary of the Invention

[0007] Determine the file size level of the video file to be uploaded, and obtain the write timeout threshold;

[0008] If the file size level is the first level, then the video file to be uploaded will be written to cloud storage for storage;

[0009] If the file size level is in the second level, and the average write time of the cloud storage is less than the average write time of the local disk of the streaming media server, then the video file to be uploaded will be written to the cloud storage for storage.

[0010] If the file size level is the second level, and the average write time of the cloud storage is greater than the average write time of the local disk of the streaming media server, and the average write time of the cloud storage is less than or equal to the write timeout threshold, then the video file to be uploaded will be written to the cloud storage for storage.

[0012] If the file size level is the third level, and the average write time of the prepared cloud storage is the minimum average write time among the average write time of the cloud storage, the average write time of the prepared cloud storage, and the average write time of the local disk of the streaming media server, then the video file to be uploaded will be written to the prepared cloud storage for storage.

[0013] If the file size level is the third level, and the average write time of the local disk of the streaming media server is the minimum average write time among the average write time of cloud storage, the average write time of the prepared cloud storage, and the average write time of the local disk of the streaming media server, and both the average write time of cloud storage and the average write time of the prepared cloud storage are greater than the write timeout threshold, then the video file to be uploaded will be written to the local disk of the streaming media server for storage.

[0020] If the file size of the video file to be uploaded is greater than the first threshold and less than or equal to the second threshold, then the file size level of the video file to be uploaded is determined to belong to the second level.

[0021] If the file size of the video file to be uploaded is greater than the second threshold and less than or equal to the third threshold, then the file size level of the video file to be uploaded is determined to belong to the third level.

[0025] In one embodiment, the step of obtaining the average write time of cloud storage includes:

[0026] Obtain the total time spent writing video files to the cloud storage and the total number of video files within the historical time period;

[0027] The average write time for cloud storage is obtained based on the total time and the total number.

[0028] In one embodiment, obtaining the write timeout threshold includes:

[0029] Get the preset timeout period;

[0042] The file sizes for the first, second, and third levels increase sequentially.

[0043] This application provides a streaming media server, including a memory and a processor, wherein the memory stores a computer program and the processor executes the above-described method.

[0045] This application provides a computer program product having a computer program stored thereon, the computer program being executed by a processor using the above-described method.

[0046] The aforementioned method, apparatus, streaming media server, storage medium, and computer program product for storing video files acquire the video file to be uploaded from the memory of the streaming media server; determine the file size level of the video file to be uploaded and obtain the write timeout threshold; if the file size level is the first level, then the video file to be uploaded is written to cloud storage for storage; if the file size level is the second level, and the average write time of cloud storage is less than the average write time of the local disk of the streaming media server, then the video file to be uploaded is written to cloud storage for storage; if the file size level is the second level, and the average write time of cloud storage is greater than the average write time of the local disk of the streaming media server, and the average write time of cloud storage is less than or equal to the write timeout threshold, then the video file to be uploaded is written to cloud storage for storage; if the file size level is the third level, and the average write time of cloud storage is equal to the average write time of cloud storage, the average write time of the pre-cloud storage, and the average write time of the streaming media server... If the average write time of the server's local disk is the minimum among the average write times of the cloud storage, the video file to be uploaded will be written to cloud storage for storage. If the file size level belongs to the third level, and the average write time of the prepared cloud storage is the minimum among the average write times of cloud storage, the average write times of the prepared cloud storage, and the average write times of the streaming media server's local disk, the video file to be uploaded will be written to the prepared cloud storage for storage. If the file size level belongs to the third level, and the average write time of the streaming media server's local disk is the minimum among the average write times of cloud storage, the average write times of the prepared cloud storage, and the average write times of the streaming media server's local disk, and both the average write times of cloud storage and the average write times of the prepared cloud storage are greater than the write timeout threshold, the video file to be uploaded will be written to the streaming media server's local disk for storage. The file sizes corresponding to the first, second, and third levels increase sequentially.The solution provided in this application sets multiple levels for the video files to be uploaded in the memory of the streaming media server to distinguish different write storage addresses. When the file size level of the video file to be uploaded belongs to the first level, it is directly written to cloud storage. When the file size level of the video file to be uploaded belongs to the second level, it is written to either cloud storage or the local disk of the streaming media server. When the file size level of the video file to be uploaded belongs to the third level, it is written to either cloud storage, backup cloud storage, or the local disk of the streaming media server. In the selection process, the average write time of each is compared to select the storage method with better performance and share the pressure, reducing the impact of the performance bottleneck of a single write method. Considering that the local disk space of the streaming media server is limited, if the average write time of cloud storage and backup cloud storage is greater than the average write time of local disk, but the average write time of cloud storage or backup cloud storage does not exceed the write timeout threshold, the video file to be uploaded can still be written to cloud storage or backup cloud storage. The solution provided in this application monitors the size of the video files to be uploaded in the memory of the streaming media server and distributes the pressure of writing to storage, preventing the program from crashing due to memory overload of the streaming media server, and ensuring the stability and reliability of cloud recording of streaming media.

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0054] The method for storing video files provided in this application includes Figure 1 The steps shown in the method can be executed by the processor of the streaming media server.

[0055] Step S101: Obtain the video file to be uploaded from the memory of the streaming media server.

[0056] Reference Figure 2 , Figure 2 The flowchart illustrates the process of a streaming media server's processor generating a video file. Specifically, in steps S201 and S202, the streaming media server's processor receives and parses the media stream data, determining the relative size between the received media stream data's duration t1 and a preset duration t2. If the media stream data's duration t1 is less than the preset duration t2, the process returns to step S201 to continue receiving media stream data. If the media stream data's duration t1 is greater than or equal to the preset duration t2, the process proceeds to step S203, where a single video file is generated based on the media stream data and stored in the streaming media server's memory's video queue. In step S204, the process determines whether the video processing thread is enabled. If the video processing thread is enabled, the video file is written to the corresponding storage address via the video processing thread, and the process returns to step S201 to continue receiving media stream data. If the video processing thread is not enabled, the process proceeds to step S205, where the video processing thread is enabled to write the video file to the corresponding storage address via the video processing thread.

[0057] Once the recording processing thread is started, the processor of the streaming media server can retrieve the recording files to be uploaded from the recording queue in the memory of the streaming media server through the recording processing thread.

[0058] Step S102: Determine the file size level of the video file to be uploaded and obtain the write timeout threshold.

[0059] The processor of the streaming media server can obtain the file size of the video file to be uploaded and determine the file size classification based on the file size. The processor can also obtain the write timeout threshold. This write timeout threshold can be a fixed value or a random value.

[0060] This application's embodiments divide the file into at least three levels, which can be referred to as the first level, the second level, and the third level; wherein the file sizes corresponding to the first level, the second level, and the third level increase sequentially.

[0061] Step S103: If the file size level is the first level, then the video file to be uploaded is written to cloud storage for storage.

[0062] If the file size level is at the first level, it means that the file size of the video file to be uploaded is relatively small, and the video file to be uploaded can be directly written to cloud storage for storage.

[0063] Step S104: If the file size level is in the second level and the average write time of the cloud storage is less than the average write time of the local disk of the streaming media server, then the video file to be uploaded is written to the cloud storage for storage.

[0064] If the file size level is in the second category, it means that the file size of the video file to be uploaded is slightly larger; at this time, the relative size between the average write time of cloud storage and the average write time of the local disk of the streaming media server can be compared.

[0065] If the average write time of cloud storage is less than the average write time of the local disk of the streaming media server, then the video files to be uploaded can be written to cloud storage for storage.

[0066] Step S105: If the file size level is the second level, and the average write time of cloud storage is greater than the average write time of the local disk of the streaming media server, and the average write time of cloud storage is less than or equal to the write timeout threshold, then the video file to be uploaded will be written to cloud storage for storage.

[0067] If the file size level is in the second category, and the average write time of cloud storage is greater than the average write time of the local disk of the streaming media server, then the relative size between the average write time of cloud storage and the write timeout threshold can be compared.

[0068] If the average write time of cloud storage is less than or equal to the write timeout threshold, it indicates that the average write time of cloud storage is within an acceptable range, and the video file to be uploaded can be written to cloud storage for storage.

[0069] Step S106: If the file size level is the third level, and the average write time of the cloud storage is the minimum average write time among the average write time of the cloud storage, the average write time of the preparatory cloud storage, and the average write time of the local disk of the streaming media server, then the video file to be uploaded will be written to the cloud storage for storage.

[0070] If the file size level is at level three, it indicates that the file size of the video file to be uploaded is relatively large. In this case, you can introduce backup cloud storage in the storage address options. At this time, the storage address options include cloud storage, backup cloud storage, and the local disk of the streaming media server.

[0071] The streaming media server's processor can compare the average write time of cloud storage, the average write time of pre-cloud storage, and the average write time of the streaming media server's local disk.

[0072] If the average write time of cloud storage is the minimum average write time, then the video file to be uploaded can be written to cloud storage for storage.

[0073] Step S107: If the file size level is the third level, and the average write time of the prepared cloud storage is the minimum average write time among the average write time of the cloud storage, the average write time of the prepared cloud storage, and the average write time of the local disk of the streaming media server, then the video file to be uploaded is written to the prepared cloud storage for storage.

[0074] If the file size level is the third level, the streaming media server's processor compares the average write time of cloud storage, the average write time of pre-cloud storage, and the average write time of the streaming media server's local disk. If it determines that the average write time of pre-cloud storage is the minimum average write time, then the video file to be uploaded can be written to the pre-cloud storage for storage.

[0075] Step S108: If the file size level belongs to the third level, and the average write time of the local disk of the streaming media server is the minimum average write time among the average write time of cloud storage, the average write time of the prepared cloud storage, and the average write time of the local disk of the streaming media server, and the average write time of cloud storage and the average write time of the prepared cloud storage are both greater than the write timeout threshold, then the recording file to be uploaded is written to the local disk of the streaming media server for storage.

[0076] If the file size level is at the third level, the streaming media server's processor compares the average write time of cloud storage, the average write time of the prepared cloud storage, and the average write time of the streaming media server's local disk, and determines the average write time of the streaming media server's local disk as the minimum average write time. Considering that the storage space of the streaming media server's local disk is limited, and storage on the local disk should be avoided as much as possible, the streaming media server's processor can also first compare the relative size between the average write time of cloud storage and the write timeout threshold, as well as the relative size between the average write time of the prepared cloud storage and the write timeout threshold.

[0077] If the average write time of cloud storage is less than or equal to the write timeout threshold, and the average write time of the cloud storage to be uploaded is greater than the write timeout threshold, then the video file to be uploaded can be written to cloud storage.

[0078] If the average write time of the cloud storage is greater than the write timeout threshold, and the average write time of the pre-cloud storage is less than or equal to the write timeout threshold, then the video file to be uploaded can be written to the pre-cloud storage.

[0079] If the average write time of cloud storage is less than or equal to the write timeout threshold, and the average write time of the pre-cloud storage is less than or equal to the write timeout threshold, then the relative size between the average write time of cloud storage and the average write time of the pre-cloud storage can be determined. If the average write time of cloud storage is less than the average write time of the pre-cloud storage, then the video file to be uploaded can be written to cloud storage. If the average write time of cloud storage is greater than the average write time of the pre-cloud storage, then the video file to be uploaded can be written to the pre-cloud storage.

[0080] If the average write time of cloud storage is greater than the write timeout threshold, and the average write time of the prepared cloud storage is greater than the write timeout threshold, then the video file to be uploaded can be written to the local disk of the streaming media server for storage.

[0081] In the above-mentioned method for processing video files, the following steps are taken: The video file to be uploaded is retrieved from the memory of the streaming media server; the file size level of the video file to be uploaded is determined, and a write timeout threshold is obtained; if the file size level is the first level, the video file to be uploaded is written to cloud storage; if the file size level is the second level, and the average write time of cloud storage is less than the average write time of the local disk of the streaming media server, the video file to be uploaded is written to cloud storage; if the file size level is the second level, and the average write time of cloud storage is greater than the average write time of the local disk of the streaming media server, and the average write time of cloud storage is less than or equal to the write timeout threshold, the video file to be uploaded is written to cloud storage; if the file size level is the third level, and the average write time of cloud storage is equal to the average write time of cloud storage, the average write time of the pre-cloud storage, and the write time of the local disk of the streaming media server... If the minimum average write time is selected from the average write times, the video file to be uploaded will be written to cloud storage for storage. If the file size level belongs to the third level, and the average write time of the preparatory cloud storage is the minimum average write time among the average write times of cloud storage, preparatory cloud storage, and the local disk of the streaming media server, then the video file to be uploaded will be written to the preparatory cloud storage for storage. If the file size level belongs to the third level, and the average write time of the local disk of the streaming media server is the minimum average write time among the average write times of cloud storage, preparatory cloud storage, and the local disk of the streaming media server, and both the average write time of cloud storage and the average write time of preparatory cloud storage are greater than the write timeout threshold, then the video file to be uploaded will be written to the local disk of the streaming media server for storage. The file sizes corresponding to the first, second, and third levels increase sequentially. The solution provided in this application sets multiple levels for the video files to be uploaded in the memory of the streaming media server to distinguish different write storage addresses. When the file size level of the video file to be uploaded belongs to the first level, it is directly written to cloud storage. When the file size level of the video file to be uploaded belongs to the second level, it is written to either cloud storage or the local disk of the streaming media server. When the file size level of the video file to be uploaded belongs to the third level, it is written to either cloud storage, backup cloud storage, or the local disk of the streaming media server. In the selection process, the average write time of each is compared to select the storage method with better performance and share the pressure, reducing the impact of the performance bottleneck of a single write method. Considering that the local disk space of the streaming media server is limited, if the average write time of cloud storage and backup cloud storage is greater than the average write time of local disk, but the average write time of cloud storage or backup cloud storage does not exceed the write timeout threshold, the video file to be uploaded can still be written to cloud storage or backup cloud storage.The solution provided in this application monitors the size of the video files to be uploaded in the memory of the streaming media server and distributes the pressure of writing to storage, preventing the program from crashing due to memory overload of the streaming media server, and ensuring the stability and reliability of cloud recording of streaming media.

[0082] In one embodiment, the method provided in this application further includes:

[0083] If the file size is classified as Level 4, an alarm message will be sent to the operations and maintenance personnel; the file size corresponding to Level 4 is greater than the file size corresponding to Level 3.

[0084] This embodiment divides the file into at least four levels, which can be referred to as Level 1, Level 2, Level 3, and Level 4; wherein the file sizes corresponding to Level 1, Level 2, Level 3, and Level 4 increase sequentially.

[0085] If the processor of the streaming media server determines that the file size of the video file to be uploaded belongs to the fourth level, it means that the current situation is out of control. Therefore, an alarm message can be sent to the maintenance personnel so that they can intervene in time.

[0086] In one embodiment, determining the file size level of the video file to be uploaded includes:

[0087] Obtain a pre-set first threshold, second threshold, and third threshold; the first threshold is less than the second threshold, and the second threshold is less than the third threshold; if the file size of the video file to be uploaded is less than or equal to the first threshold, then the file size level of the video file to be uploaded is determined to be the first level; if the file size of the video file to be uploaded is greater than the first threshold and less than or equal to the second threshold, then the file size level of the video file to be uploaded is determined to be the second level; if the file size of the video file to be uploaded is greater than the second threshold and less than or equal to the third threshold, then the file size level of the video file to be uploaded is determined to be the third level; if the file size of the video file to be uploaded is greater than the third threshold, then the file size level of the video file to be uploaded is determined to be the fourth level.

[0088] In this embodiment, a pre-set first threshold (which can be denoted as s1), a second threshold (which can be denoted as s2), and a third threshold (which can be denoted as s3) can be obtained, where the first threshold s1 is greater than the second threshold s2, and the second threshold s2 is greater than the third threshold s3. The file size of the video file to be uploaded can be denoted as s. In some scenarios, the first threshold s1 can be set to 100GB, the second threshold s2 can be set to 200GB, and the third threshold s3 can be set to 300GB.

[0089] If the file size *s* of the video file to be uploaded is less than or equal to the first threshold *s1*, then the file size level of the video file to be uploaded is determined to be Level 1. If the file size *s* of the video file to be uploaded is greater than the first threshold *s1* and less than or equal to the second threshold *s2*, then the file size level of the video file to be uploaded is determined to be Level 2. If the file size *s* of the video file to be uploaded is greater than the second threshold *s2* and less than or equal to the third threshold *s3*, then the file size level of the video file to be uploaded is determined to be Level 3; if the file size *s* of the video file to be uploaded is greater than the third threshold *s3*, then the file size level of the video file to be uploaded is determined to be Level 4.

[0090] In one embodiment, the method provided in this application further includes:

[0091] If the file size is in the second category, and the average write time of cloud storage is greater than the average write time of the local disk of the streaming media server, and the average write time of cloud storage is greater than the write timeout threshold, then the recording file to be uploaded will be written to the local disk of the streaming media server for storage.

[0092] If the file size level is in the second category, the streaming media server's processor can compare the relative size between the average write time of cloud storage and the average write time of the streaming media server's local disk.

[0093] If the average write time of cloud storage is greater than the average write time of the local disk of the streaming media server, the processor of the streaming media server can compare the relative size between the average write time of cloud storage and the write timeout threshold.

[0094] If the average write time of cloud storage is greater than the write timeout threshold, it indicates that the average write time of cloud storage is outside the acceptable range. In this case, the video files to be uploaded can be written to the local disk of the streaming media server for storage.

[0095] In one embodiment, the step of obtaining the average write time of the local disk of the streaming media server includes:

[0096] Get the total time spent writing video files to the local disk and the total number of video files within the historical time period; based on the total time and the total number of files, get the average write time to the local disk.

[0097] Historical time periods can be those close to the current time, such as the minute before the current time.

[0098] The streaming media server's processor can obtain the total time spent writing recording files to the local disk in the previous minute (denoted as tas), and also the total number of recording files written to the local disk in the previous minute (denoted as na). The total time spent writing recording files to the local disk (tas) is divided by the total number of recording files written to the local disk (na), and the result is taken as the average write time to the local disk. If the average write time to the local disk is denoted as ta, it can be expressed by the formula ta = tas / na; where, if the total number of recording files written to the local disk (na) is 0, then the average write time to the local disk (ta) is also 0.

[0099] In one embodiment, the step of obtaining the average write time of cloud storage includes:

[0100] Obtain the total time spent writing video files to cloud storage and the total number of video files within the historical time period; based on the total time spent and the total number of files, obtain the average write time to cloud storage.

[0101] Historical time periods can be those close to the current time, such as the minute before the current time.

[0102] The streaming media server's processor can obtain the total time spent writing video files to cloud storage in the previous minute (denoted as tbs), and also the total number of video files written to cloud storage in the previous minute (denoted as nb). The total time spent writing video files to cloud storage (tbs) is divided by the total number of video files written to cloud storage (nb), and the result is taken as the average write time to cloud storage. If the average write time to cloud storage is denoted as tb, it can be expressed by the formula tb = tbs / nb; where, if the total number of video files written to cloud storage (nb) is 0, then the average write time to cloud storage (tb) is also 0.

[0103] In one embodiment, the step of obtaining the average write time of the prepared cloud storage includes:

[0104] Obtain the total time spent writing video files to the cloud storage within the historical time period, as well as the total number of video files; based on the total time and the total number, obtain the average write time to the cloud storage.

[0105] Historical time periods can be those close to the current time, such as the minute before the current time.

[0106] The processor of the streaming media server can obtain the total time spent writing video files to the cloud storage in the previous minute (denoted as tcs), and also the total number of video files written to the cloud storage in the previous minute (denoted as nc). The total time spent writing video files to the cloud storage (tcs) is divided by the total number of video files written to the cloud storage (nc), and the result is taken as the average write time to the cloud storage. If the average write time to the cloud storage is denoted as tc, it can be expressed as tc = tcs / nc; where, if the total number of video files written to the cloud storage (nc) is 0, then the average write time to the cloud storage (tc) is also 0.

[0107] In one embodiment, obtaining the write timeout threshold includes:

[0108] Get the preset timeout period; divide the random number by the timeout period and get the integer result; based on the integer, get the write timeout threshold.

[0109] The preset timeout period can be denoted as 'to', and 'to' can be set to 600 milliseconds. A random number can be generated using a random number generator. This random number is then divided by the timeout period 'to', and the integer result is used as the write timeout threshold (denoted as 'tr'). The write timeout threshold obtained in this way is a random value. The random number generator can be 'rand()'.

[0110] To better understand the above method, the following details an application example of the video file storage method of this application. The first threshold, second threshold, and third threshold involved in this application example are denoted as s1, s2, and s3, respectively. (Refer to...)

[0112] In step S302, the processor can determine the file size s of the video recording file to be uploaded;

[0113] In step S303, the processor can calculate the average write time ta of the local disk of the streaming media server.

[0114] In step S304, the processor can write the timeout threshold tr.

[0115] Step S305: The processor determines whether the file size s of the video file to be uploaded is greater than the first threshold s1; if not, proceed to step S306; if yes, proceed to step S307.

[0116] Step S306: The processor writes the video file to be uploaded to the cloud storage;

[0117] Step S307: The processor determines whether the file size s of the video file to be uploaded is greater than the second threshold s2; if not, proceed to step S308; if yes, proceed to step S312.

[0118] Step S308: The processor calculates the average write time tb for cloud storage;

[0119] Step S309: The processor determines whether the average write time ta of the local disk is greater than the average write time tb of the cloud storage; if yes, proceed to step S310; if no, proceed to step S306.

[0120] In step S310, the processor determines whether the average write time tb of the cloud storage is greater than the write timeout threshold tr; if yes, proceed to step S311; if no, proceed to step S306.

[0121] Step S311: The processor writes the video file to be uploaded to the local disk;

[0122] Step S312: The processor determines whether the file size s of the video file to be uploaded is greater than the third threshold s3; if not, proceed to step S313; if yes, proceed to step S318.

[0123] Step S313: The processor calculates the average write time tc of the prepared cloud storage.

[0124] Step S314: The processor determines whether the average write time tb of the cloud storage is greater than the average write time tc of the prepared cloud storage; if not, proceed to step S309; ​​if yes, proceed to step S315.

[0125] Step S315: The processor determines whether the average write time tc of the cloud storage to be prepared is greater than the average write time ta of the local disk; if not, proceed to step S317; if yes, proceed to step S316.

[0126] Step S316: The processor determines whether the average write time tc of the cloud storage to be prepared is greater than the write timeout threshold tr; if yes, proceed to step S311; if no, proceed to step S317.

[0127] Step S317: The processor writes the video file to be uploaded to the pre-cloud storage;

[0128] In step S318, the processor sends an alarm notification message.
