Embodiment
Specifically describe preferential embodiment of the present invention below in conjunction with accompanying drawing, wherein, accompanying drawing constitutes the application's part, and is used from explaination principle of the present invention with embodiments of the invention one.
1 be described in detail at first, in conjunction with the accompanying drawings to 4 pairs of described methods of the embodiment of the invention of accompanying drawing.
At first, CDN pre-sets 3 database tables in its database, be respectively: source record task list, target record task list and mapping table.Wherein, the source record task list is used for storing the target record task that Surveillance center has issued; After being used for depositing and splitting, the target record task list prepares to be handed down to the target record task of streaming media server; Mapping table be used for preserving the target record task that issued and split after the corresponding relation of target record task.
As shown in Figure 1, Fig. 1 is the schematic flow sheet of the described method of the embodiment of the invention, specifically can comprise the steps:
Step 101: Surveillance center is provided with new original record task, i.e. the record task that does not split;
Step 102: the new original record task that Surveillance center will be provided with is handed down to CDN (content delivery network);
When step 103:CDN receives the new original record task of Surveillance center, described new original record task is split into one or more target record task to be inserted in target record task list and the mapping table, target record task to be issued in the timing scan target record task list then, in advance (as 5 seconds) issue the video recording initiation command and give streaming media server;
Step 104: streaming media server obtains code stream from front monitoring front-end immediately, and the code stream that obtains is write on the magnetic battle array of streaming media server after receiving and beginning the video recording order;
Step 105: video time finishes, and streaming media server stops to obtain code stream from front monitoring front-end, and the code stream that will obtain saves as the video file of professional required form;
Step 106: the streaming media server result that will record a video reports CDN;
The video recording result that step 107:CDN reports according to streaming media server, the state of the target record task in the modifying target record task list, and according to end-state that should new original record task in the status modifier source record task list of record task in the goal task table (state of this new original video recording in the record task list of source be not for issuing treatment state, after at least one corresponding with this new ancestral task in goal task table target record task all distributes down, the status modifier of this new original record task in the record task list of source disposes for issuing), the result that will record a video then reports Surveillance center.
Because in the global eye, video recording mainly is divided into three kinds of video recordings: regularly video recording, manually video recording, alarm video recording, so in the step 101, when Surveillance center is provided with new original record task, at 3 kinds of video recordings, do following processing respectively: for regularly video recording, Surveillance center sets time started of record task and concluding time according to service needed value is deposited in the database; For manual video recording, Surveillance center sets the manually duration of video recording, and the time started that global eye is manually recorded a video automatically is set to the current time, and the concluding time is the duration that the current time adds manual record setting; For the alarm video recording, camera is checked out when alarm event takes place, and notifies Surveillance center immediately, and global eye is according to the alarm duration of monitoring according to setting, the current time of alarm video recording is set at the current alarm time, and the time started of concluding time for the alarm video recording adds the alarm duration.
To in the step 103, the process that new original record task splits is described in further detail below.
CDN is when being split as the target record task with record task, and definition the greatly enhancing most an of record task is used for guaranteeing that the target record task is unlikely to excessive, cause the record task failure after, whole video file destroys.The embodiment of the invention can also define an elastic length, after being used for guaranteeing that record task splits by maximum, if the remaining record task time very short (less than elastic length), then should not generate a video file to this section record task separately (because may produce more very little video file like this, inconvenience is safeguarded), directly it is appended on the previous record task.
As shown in Figure 2, Fig. 2 is in the described method of the embodiment of the invention, step 1 03, and promptly the schematic flow sheet that new original record task is split specifically can comprise the steps:
Step 201:CDN receives the new original record task that Surveillance center issues;
Step 202: it is the new original record task time started that issues that variable P is set;
Step 203: check the target record task of having stored in the target record task list, the new original record task time-interleaving or the partly overlapping target record task that whether exist Yu issue, if exist, then execution in step 204, otherwise change step 215; In order to narrate conveniently, below the target record task of having stored in the target record task list is become old target record task;
Step 204:, carry out time started rank order from small to large to the overlapping or partly overlapping old target record task of all life periods of finding out;
Step 205: judge whether to have traveled through the old target record task that all are found out,,, otherwise forward step 211 to then to current old target record task execution in step 206 if do not traveled through;
Step 206: judge P whether less than time started of current old target record task, if execution in step 207 then, otherwise when promptly P was more than or equal to the beginning of current old target record task, then execution in step 210;
Step 207: the time started of more current old target record task and the difference of P whether less than the maximum duration of record task and record task elasticity duration with, promptly, the elasticity duration of the maximum duration+record task of the time started-P of current old target record task＜record task, if, then execution in step 208, otherwise execution in step 209; In the preferred plan of the embodiment of the invention is the condition that adopts the maximum duration of record task and record task elasticity duration and conduct and P compare, but it will be recognized by those skilled in the art that the maximum duration conduct of independent employing record task also is fine with the condition that P compares;
Step 208: insert a target record task to the target record task list, time started is P, concluding time is the time started of old target record task, and P is changed to the old target record task concluding time, the corresponding relation that inserts new original record task and old target record task simultaneously records mapping table, and execution in step 205;
Step 209: insert a target record task to the target record task list: the time started is P, concluding time is the maximum duration that P adds record task, and P is changed to the maximum duration that P adds record task, corresponding relation with new original record task and old target record task is inserted into mapping table simultaneously, and changes step 206;
Step 210: insert a target record task in mapping table, and P is changed to the old target record task concluding time, and turn to step 205;
Whether step 211:P less than the new original record task concluding time, if, execution in step 212, otherwise, if promptly P equals the new original record task concluding time, then directly forward step 215 to;
Step 212: the difference of judging new original record task concluding time and P whether less than the maximum duration of record task and record task elasticity duration with, promptly, the elasticity duration of the maximum duration+record task of fresh target record task concluding time-P＜record task, if, then execution in step 213, otherwise execution in step 214;
Step 213: insert a target record task to target record task list and record task mapping table, time started is P, concluding time is the new original record task concluding time, and P is changed to the new original record task concluding time, and execution in step 215 then;
Step 214: insert a target record task to target record task list and record task mapping table, the time started is P, and the concluding time is the maximum duration that P adds record task; P is changed to the maximum duration that P adds record task, and forwards step 211 to;
Step 215: new original record task is inserted into the source record task list.
For the ease of understanding the flow process that splits for new ancestral task, contrast accompanying drawing 2 is explained to this flow process in more detail by two examples below.
Example one, database were empty originally, promptly without any record task (source record task list, target record task list, mapping table all are empty).The elasticity duration of the maximum duration of video recording is set to 1 hour (can set according to actual conditions), video recording is 0.5 hour (can set according to actual conditions).
1. Surveillance center issues record task and gives CDN, and the time started is the 5:00 point, and the concluding time is 7:45.(201)
2. variable P=5:00 is set.(202)
3. judge and whether have the old target record task overlapping in the object table with the new original record task time period (P-7:45).Owing to without any record task,, will carry out 211 flow processs in the target record task list so do not deposit overlapping old target record task.(203)
Because P (=5:00)＜7:45, so will carry out 212 flow processs.(211)
5. because new original record task concluding time 7:45-P (5:00)=2.75 hour, and the elasticity duration of the 1 hour+record task of maximum duration of record task 0.5 hour=1.5 hours.2.75 greater than 1.5 hours, so will carry out 214 flow processs.(212)
6. (time started is P (5:00), and the concluding time is the maximum duration (1 hour)=6:00) of P+ record task to the target record task list to insert a record d_R1; (s_R1 is d_R1) to mapping table to insert a record; Reset 1 hour=6:00 of the maximum duration of P=P (5:00)+record task.This moment, original new record task became (6:00-7:45); Change 212.(214)
7. because concluding time 7:45-P (6:00)=1.75 hour of new original record task, and the elasticity duration of the 1 hour+record task of maximum duration of record task 0.5 hour=1.5 hours.1.75 greater than 1.5 hours, so will carry out 214 flow processs.(212)
8. (time started is P (6:00), and the concluding time is the maximum duration (1 hour)=7:00) of P+ record task to the target record task list to insert a record d_R2; (s_R1 is d_R2) to mapping table to insert a record; Reset 1 hour=7:00 of the maximum duration of P=P (6:00)+record task.This stylish original record task becomes (7:00-7:45); Change 212.(214)
9. because new original record task concluding time 7:45-P (7:00)=0.75 hour, and the elasticity duration of the 1 hour+record task of maximum duration of record task 0.5 hour=1.5 hours.0.75 less than 1.5 hours, so will carry out 213 flow processs.(212)
10. (time started is P (7:00), and the concluding time is the concluding time (7:45) of new original record task to the target record task list to insert a record d_R3; (s_R1 is d_R3) to mapping table to insert a record; Reset the concluding time=7:45 of the new original record task of P=.Change 215.(213)
11, insert a record s_R1 in the record task list of source, flow process finishes.(215)
The new original record task of example one is through after the above-mentioned fractured operation, and the record in its source record task list, target record task list and the mapping table as shown in Figure 3.
Example two,
1. on the basis of example 1, Surveillance center issues new original record task again and gives CDN, and the time started is 6:20, and the concluding time is the 8:10 branch.(201)
2. variable P=6:20 (202) is set
3. judge whether exist in the object table and (P-8:10) overlapping record task of new original record task time period,, will carry out 204 flow processs owing to exist in the target record task list.(203)
4. find out overlapping old target record task d_R2, d_R3.By time started rank order from small to large, the ordering back is d_R2, d_R3 with the target record task found out.(204)
5. check the target record task after whether having traveled through all sorts, owing to also do not begin traversal, so will carry out 206 flow processs.(205)
6. check that P (6:20) whether less than the time started (6:00) of d_R2, because P is not less than the time started of d_R2, will carry out 210.(206)
7. (s_R2 d_R2), is changed to P the concluding time (being P=7:00) of old target record task to mapping table to insert a task.This stylish original record task becomes (7:00-8:10); Change 205.(210)
8. check the target record task after whether having traveled through all sorts, owing to also do not travel through d_R3, so will carry out 206 flow processs.(205)
9. check that P (7:00) whether less than the time started (7:00) of d_R3, because P is not less than the time started of d_R3, will carry out 210.(206)
10. (s_R2 d_R3), is changed to P the concluding time (being P=7:45) of old goal task to mapping table to insert a target record task.This stylish original record task becomes (7:45-8:10); Change 205.(210)
11. check the target record task after whether having traveled through all sorts, owing to travel through, so will carry out 211 flow processs.(205)
12. because P (=7:45)＜and 8:10, so will carry out 212 flow processs.(211)
13. because concluding time 8:10-P (7:45)=5/12 hour of new original record task, and the elasticity duration of the 1 hour+record task of maximum duration of record task 0.5 hour=1.5 hours.5/12 less than 1.5 hours, so will carry out 213 flow processs.(212)
14. (time started is P (7:45), and the concluding time is the concluding time (8:10) of new record task to the target record task list to insert a record d_R4; (s_R2 is d_R4) to mapping table to insert a record; Reset the concluding time=8:10 of the new original record task of P=.Change 215.(213)
15, insert a record s_R2 in the record task list of source, flow process finishes.(215)
After the new original record task of example two was advanced above-mentioned intact fractured operation, the record of its source record task list, target record task list and mapping table as shown in Figure 4.
