Fig. 5 is a schematic diagram of a change process of a wait queue changing with current time in a streaming media task management method according to an embodiment of the present application, please refer to fig. 5:

after setting waiting time for each streaming media task in a waiting queue according to current time and execution time of each streaming media task, obtaining a waiting queue one 51, wherein the waiting queue one 51 comprises each streaming media task and the waiting time of each streaming media task, the waiting queue one 51 comprises the waiting time of a task one 511 and a task one 511 which are positioned at head positions, namely after the absolute time is 1 second, the waiting time of a task two 512 and a task two 512 which are positioned at non-head positions, namely after the relative time is that the task one executes for 3 seconds, the waiting time of a task three 513 and a task three 513, namely after the relative time is that the task two executes for two seconds, …, the waiting time of a task N which is marked 514 and the waiting time of a task N which is marked 514 are marked after the task N-1 executes for k seconds;

taking the time axis T as an example, assuming that after the current time changes by 0.5 second, the waiting queue one 51 becomes the waiting queue two 52, and meanwhile, the waiting queue two 52 only needs to change the waiting time of the task one 521 at the head position, that is, the absolute time of the task one 521 is updated to 0.5 second from 1 second, and the waiting time of the task two 512 at the non-head position to the task N with the reference numeral 514 does not need to be updated;

with the change of the current time, when the execution time of the task one 521 at the head position of the waiting queue two 52 arrives, that is, the waiting time is 0, the waiting queue two 52 is updated to the waiting queue three 53, the task one 521 at the head position in the waiting queue two 52 is added to the execution queue, the waiting time of the streaming media task at the head position of the waiting queue three 53 is updated to the task two 531, the waiting time of the task two 531 is set to be absolute time, that is, after 3 seconds, and the waiting time of the task three 513 after the task two 531 to the task N with the reference number 514 does not need to be updated.

The embodiment of the present application provides a change process of a waiting queue changing with current time in a streaming media task management method, and as can be seen from the change process of the waiting queue, when updating the waiting time of a streaming media task, only the waiting time of the streaming media task located at the head position in the waiting queue needs to be updated, and the waiting time of the streaming media task located at the non-head position in the waiting queue does not need to be updated, so that the amount of data to be changed is reduced.

206: and when the execution time of the streaming media task is reached, adding the streaming media task into the execution queue from the waiting queue, and recording the initial time of starting the execution of the streaming media task.

In one embodiment, the detecting of the execution state of the streaming media task may be performed at an initial time of recording the streaming media task, and a time when the streaming media task starts to be executed is taken as the initial time of the streaming media task, so that the initial time of the streaming media task is the time when the streaming media task starts to be executed, and the step includes: after the streaming media task is added into an execution queue from a waiting queue, detecting the execution state of the streaming media task; when the streaming media task starts to execute, recording the moment when the streaming media task starts to execute as the initial time of the streaming media task; specifically, considering that the streaming media task is not executed immediately after the streaming media task is added to the execution queue from the waiting queue, the actual execution starting time of the streaming media task may be detected, and the actual execution starting time of the streaming media task is taken as the initial time of the streaming media task.

In an embodiment, when detecting the execution state of the streaming media task, the execution state of the streaming media task may be detected in real time, or the execution state of the streaming media task may be detected at a certain time interval, so that the initial time of the streaming media task may be detected.

In an embodiment, when recording the execution time of the streaming media task, the time for the streaming media task to join in the execution queue may also be recorded, and the initial time of the streaming media task is obtained according to the joining time of the streaming media task, this step includes: when the streaming media task is added into the execution queue from the waiting queue, recording the adding time of the streaming media task, and obtaining the initial time of the streaming media task according to the adding time of the streaming media task; specifically, considering that the streaming media task is executed after a certain time after being added to the execution queue, the initial time of the streaming media task may be obtained according to the time for the streaming media task to be added to the waiting queue, for example, the time for the streaming media task to be added from the waiting queue to the execution queue is 12: 00:00, after the streaming media task is added to the execution queue, the streaming media task is executed after 3 seconds, and then 12: 00: 03 is used as the initial time of the streaming media task, and the initial time of the streaming media task can be obtained according to the adding time of the streaming media task; when the initial time of the streaming media task is obtained according to the joining time of the streaming media task, the joining time of the streaming media task from the waiting queue to the execution queue can be used as the initial time, that is, considering that each executed streaming media task needs to be joined to the execution queue, the joining time of the streaming media task can be used as the initial time, so as to judge whether the execution of the streaming media task is overtime according to the initial time.

207: and when the execution of the streaming media task is completed, recording the end time of the completion of the execution of the streaming media task.

In an embodiment, the execution state of the streaming task may be detected when the end time of the completion of the execution of the streaming task is recorded, the execution state of the streaming task is detected after the streaming task starts to be executed, and the end time of the completion of the execution of the streaming task may be recorded when the completion of the execution of the streaming task is detected.

208: and judging whether the time interval between the initial time and the ending time is greater than the preset time or not according to the initial time and the ending time.

In an embodiment, the preset time refers to a time set for the streaming media task to complete an execution process of the streaming media task, and the time may be a time when the streaming media task occupies a thread, or a time when the streaming media task is added to an execution queue until the streaming media task is completed.

In an embodiment, when determining whether the streaming media task is executed overtime, the preset time of the streaming media task is further obtained, and whether the streaming media task is executed overtime is determined according to a comparison between an actual execution time of the streaming media task and the preset time, and when the preset time of the streaming media task is set, the preset time can be set for each streaming media task according to a data volume of each streaming media task, that is, considering that the data volume of each streaming media task is different, more time can be allocated to the streaming media task with a larger data volume, so that the time of the streaming media task occupying a thread during execution is longer, and the execution of the streaming media task is completed, the step includes: acquiring the data volume of each streaming media task; distributing corresponding occupied time for each streaming media task according to the data volume of each streaming media task; acquiring preset time of each streaming media task according to the occupied time of each streaming media task; specifically, for example, when the data server receives task execution requests of streaming media tasks sent by two front-end cameras, video data sent by the front-end cameras needs to be processed to obtain traffic violation data corresponding to the video data, assuming that the data volume of one video data is 10 megabytes and the data volume of the other video data is 20 megabytes, occupation time can be allocated to the two streaming media tasks according to the data volume of the two video data, that is, the time that a streaming media task with the data volume of 20 megabytes occupies a thread is greater than the streaming media task with the data volume of 10 megabytes, so that the preset time of the streaming media task can be set according to the data volume of the streaming media task, and then whether the streaming media task is executed overtime is determined according to comparison between the preset time of the streaming media and a difference between the initial time and the end time of the streaming media task.

In an embodiment, when obtaining the preset time of the streaming media task according to the occupation time of the streaming media task, considering that the initial time of the streaming media task takes the time when the streaming media task joins the execution queue as the initial time, and the streaming media task is executed within a certain time after joining the execution queue, therefore, the preset time of the streaming media task can be obtained according to the time when the streaming media task joins the execution queue and the occupation time of the streaming media task, that is, assuming that the streaming media task will be executed after 3 seconds after joining the execution queue, when taking the time when the streaming media task joins the execution queue as the initial time, the preset time of the streaming media task can be made to be the sum of the occupation time after 3 seconds, as shown in fig. 7, taking a time axis t as an example, assuming that a current time 71 is 12:59: 57, in this case, the wait queue 72 has an execution time of 13:00: task one 721, execution time of 00 is 13:00: task two 722 and execution time of 03 are 13:00:05, task three 723, assuming that the execution time of the streaming media task is the time for the streaming media task to join the execution queue, and the time for the streaming media task to join the execution queue is the initial time, that is, the initial time of task one 721 is 13:00: 00, as time goes by, after 3 seconds, task one 721 is added to the execution queue 73, and when task one 721 is added to the execution queue, the preset time of task one 721 is also obtained, and assuming that the occupied time set for task one 721 is 10 seconds, the preset time of task one 721 can be set to 13 seconds, and then according to the initial time of task one 721 and the end time of task one 721, it is determined whether the time interval between the initial time and the end time of task one 721 is greater than 13 seconds, so as to determine whether task one 721 is executed overtime.

It should be noted that, in fig. 7, when task one 721 is added from wait queue 72 to execution queue 73, the wait queue is updated, and the updated wait queue is not shown in fig. 7.

In an embodiment, when a time interval between adding the streaming media task to the execution queue and executing the streaming media task is obtained, the historical data may be counted to obtain the time interval, for example, the time between adding each streaming media task to the execution queue and the time for executing each streaming media task in the historical data are obtained, and the time interval between adding each streaming media task to the execution queue and executing each streaming media task is determined according to the time between adding each streaming media task to the execution queue and the time for executing each streaming media task.

In an embodiment, when the preset time of the streaming media task is obtained according to the occupied time of the streaming media task, the occupied time of the streaming media task can be directly used as the preset time of the streaming media task, that is, the time of the streaming media task executed in the thread is used as the preset time of the streaming media task, and when the time of the streaming media task occupying the thread exceeds the preset time, the execution timeout of the streaming media task is determined.

In an embodiment, the preset time may be obtained according to the execution time of the next streaming media task and the initial time of the streaming media task, that is, after the initial time of the streaming media task is determined, considering that the next streaming media task will be added to the execution queue for execution, and the next streaming media task will be executed within a certain time interval after being added to the execution queue, so that the initial time of the streaming media task may be set according to the execution time of the next streaming media task, where the step includes: acquiring the execution time of the next streaming media task of the streaming media task; obtaining the preset time according to the initial time of the streaming media task and the execution time of the next streaming media task; specifically, for example, in order to avoid the streaming media task from being accumulated in the execution queue, the streaming media task may be executed immediately after being added to the execution queue, or the streaming media task may be executed after a certain time interval after being added to the execution queue, for example, the streaming media task may be executed after 3 seconds after being added to the execution queue, after the initial time of the streaming media task is determined, the time when the next streaming media starts to be executed may be obtained according to the execution time of the next streaming media task and the time interval from when the next streaming media task is added to the execution queue to start to be executed, and then the preset time of the streaming media task may be determined by using the difference between the time when the next streaming media starts to be executed and the initial time of the streaming media task; when the preset time is determined by using the execution time of the next streaming media task and the initial time of the streaming media task, the data volume of each streaming media task may be considered, and when the data volume of the previous streaming media task is large, the next streaming media task may be executed after a relatively long time after being added to the execution queue, for example, the data volume of the task one is greater than that of the task two, and the data volume of the task two is greater than that of the task three, then after the task one is executed, after the task two is added to the execution queue, the task two may be executed after 3 seconds, and after the task two is executed, after the task three is added to the execution queue, the task three may be executed after 2 seconds, even if the execution time of the streaming media task with a large data volume is relatively large, the specific implementation may refer to the manner in which different occupation times are allocated to the streaming media tasks with different data volumes in the above embodiment, and will not be described in detail herein.

209: and when the time interval between the initial time and the ending time is greater than the preset time, alarming.

In one embodiment, when the time interval between the initial time and the end time of the streaming media task is greater than the preset time, it indicates that the streaming media task is executed overtime, and an alarm may be performed, and when an alarm is performed, an alarm may be performed by displaying different indicator lights on a display interface, or by a pop-up window, or by a warning sound, and at the same time, the streaming media task information and the time interval between the initial time and the end time may be recorded during the alarm, so as to obtain the log information, so that corresponding processing may be performed according to the log information during subsequent repairing of the program, which includes: when the time interval between the initial time and the end time is greater than the preset time, recording streaming media task information and the time interval between the initial time and the end time; alarming according to the streaming media task information and the time interval between the initial time and the ending time; specifically, when the time interval between the initial time and the ending time is greater than the preset time, the execution of the streaming media task is overtime, at this time, an alarm can be made to indicate that the execution of the streaming media task is overtime, and information of the streaming media task can be recorded, including task content of the streaming media task, execution time of the streaming media task, initial time of the streaming media task, ending time of the streaming media task, preset time of the streaming media task, a sending object of the streaming media task, namely, a front-end device initiating a request for executing the streaming media task, a position of the streaming media task, namely, a position where the streaming media task is in a waiting queue, a storage position of the streaming media task, and the like, a thread for executing the streaming media task, and a time interval between the initial time and the ending time, and the data can be recorded as an alarm log and the alarm log is stored, even if the program can not be modified, when the data server and the front-end equipment are repaired subsequently, the position of the overtime execution of the streaming media task, the overtime time of the execution of the streaming media task and the sending object of the streaming media task can be quickly determined according to the alarm log, so that the front-end equipment and the data server can be repaired according to the information, the efficiency is higher when the overtime execution of the streaming media task is accelerated, the corresponding information of the overtime execution of the streaming media task can be obtained according to the alarm log, the program or the data server and the front-end equipment can be repaired according to the information, the overtime execution of the streaming media task is avoided, for example, the streaming media task obtains traffic violation data for processing video data sent by the front-end equipment, after the alarm log is obtained, after the execution of the follow-flow media task is completed, the data server and the front-end device are detected, for example, during detection, the front-end device sending the video data can be determined according to the information of the streaming media task, so that the problem that the execution of the streaming media task is overtime due to slow thread processing can be solved, and the data server and the front-end device are repaired correspondingly. As shown in fig. 8, an alarm may be given by using an indicator 82 on a display interface 81, and at the same time, streaming media task information 83 and a time interval 84 between an initial time and an end time may be displayed on the interface, and when the alarm is given by using the indicator 82, different colors may be used to give different degrees of alarm, for example, the time for the streaming media task to execute timeout is only 0.01 second, a yellow indicator may be used to indicate that the timeout is small, and when the time for the timeout is 1 second, a red indicator may be used to indicate that the timeout is large.

In one embodiment, when the time interval between the initial time and the ending time of the streaming media task is greater than the preset time, acquiring the time difference value between the time interval of the initial time and the ending time of the streaming media task and the preset time, setting the preset time difference value, when the time difference is smaller than or equal to the preset time difference, a first alarm is given, when the time difference is larger than the preset time difference, a second alarm is given, namely, a certain time error occurs in the process of executing the streaming media task, so that when the time difference is less than or equal to the preset time difference, a first alarm is given, when the time difference value is larger than the preset time difference value, a second alarm is carried out to show that the execution overtime problem occurs, the first alarm and the second alarm can adopt the indicator lamps with different colors to carry out alarm, and the preset time difference value can be set according to the requirement.

In an embodiment, when the time interval between the initial time and the ending time of the streaming media task is greater than the preset time, in order to enable other streaming media tasks to be executed normally, the influence of the time part that the time interval between the initial time and the ending time of the streaming media task exceeds the preset time needs to be eliminated, the preset time of part of the streaming media task can be modified, and the execution speed of the streaming media task is accelerated, so that the influence of the overtime part is eliminated within a certain time, and the influence of the overtime part can be eliminated by eliminating the overdue task in the waiting queue and adopting the preset time of the overdue task, and this step includes: detecting streaming media tasks in a waiting queue, and determining whether an overdue task exists in the waiting queue; when an overdue task exists in the waiting queue, acquiring preset time of the overdue task; reallocating the preset time of the streaming media task according to the preset time of the overdue task; specifically, after the streaming media task is executed for 10 seconds, and after the alarm is obtained, the streaming media task in the waiting queue is detected, when the expired tasks exist in the waiting queue, the expired tasks can be deleted, the preset time of the expired tasks is distributed to other streaming media tasks, so that other streaming media tasks are free from the influence of the timeout portion, for example, the preset time of the expired task is 5 seconds, if 5 streaming media tasks exist between the streaming media task and the overdue task, the preset time of each streaming media task can be reduced by 1 second, and the ending time of each streaming media task is delayed by 1 second backwards, therefore, the streaming media task after the overdue task can be executed according to the execution time, and the delay of the execution time of all subsequent streaming media tasks caused by the execution of the overtime streaming media task and even the failure of the execution of the streaming media task are avoided.

In an embodiment, when the time interval between the initial time and the ending time is greater than the preset time, an alarm is issued, in order to avoid that the execution time of the stream media task overtime affects the execution times of other stream media tasks in the waiting queue, a part of the stream media task may be adopted to repair the overtime, so that the other stream media tasks are normally executed, and the preset time of the part of the stream media task may be updated, so as to eliminate the overtime of the stream media task, which includes: updating the preset updating time of the first streaming media task in the waiting queue according to the time interval between the initial time and the end time; executing the first streaming media task according to the updating preset time of the first streaming media task in the waiting queue; specifically, after the execution of the streaming media task is overtime, the preset time of a part of the streaming media tasks in the waiting queue can be updated, so that the preset time of a part of the streaming media tasks in the waiting queue is reduced, and the subsequent streaming media tasks can be executed according to the execution time, for example, after the execution of the streaming media task is overtime, the overtime time of the streaming media task is 5 seconds, so that the preset time of the subsequent streaming media tasks can be shortened, for example, the preset time of the subsequent 5 streaming media tasks is shortened, and the preset time of each streaming media task is shortened by 1 second, so that the streaming media task can be normally executed from the 6 th streaming media task; for example, the streaming media task is to process video data sent by 10 front-end devices to obtain corresponding illegal data, and if the execution of the streaming media task is overtime when the video data sent by the 1 st front-end device is processed, the preset time from the 2 nd to the 6 th streaming media task can be reduced, so that the 7 th to the 10 th streaming media tasks can be executed on time, thereby avoiding the problem that the execution of other streaming media tasks is delayed after the execution of the streaming media task is overtime.

The embodiment of the application provides a streaming media task management method, which can determine whether a streaming media task is executed overtime or not by judging the time interval between the initial time and the ending time of the streaming media task and the size of the preset time, alarm after the execution of the streaming media task is overtime, and record the information of the streaming media task and the overtime time of the streaming media task, so that the execution time of the streaming media task can be modified, all tasks cannot be executed according to the execution time, and the information of the streaming media task and the like can be recorded to obtain an alarm log, so that the position where the execution is overtime and the corresponding information can be quickly found when a program is subsequently repaired, and the efficiency of finding the streaming media task which is executed overtime is high.
