Target video clip is the video clip for being identified with intelligent event information, and intelligent event information is is used to indicate video recording There are the mark of predeterminable event in the video frames of segment, predeterminable event includes mobile object or target face in video frames Etc. events.
Since video file is in storage, one index file of storage can be corresponded to, video recording text is included at least in index file Duration information, channel information, the intelligent event information of part.Intelligent event is carried according to index file and playback duration point retrieval to believe The video clip of breath.
Intelligent event information generally include the type of intelligent event, the intelligence event corresponding start time and at the end of It carves, the type of intelligent event includes：Mobile detection, intrusion detection, setting-out detection and infrared detection.Mobile detection is to mobile Object is detected；Intrusion detection is to enter target area to object to be detected；Setting-out detection is in monitoring area inside-paint one Warning line, is detected the object for crossing warning line；Infrared detection is that the biology of target area is carried out by infrared ray Detection.According to the type of intelligent event included in index file, the video file of intelligent event is determined, further according to beginning Moment and finish time determine target video clip corresponding start time and finish time.For example the type of intelligent event is Mobile detection, start time corresponding date Hour Minute Second be 2016-11-30-20-08-00, the finish time corresponding date Hour Minute Second is 2016-11-30-20-15-22, then the moment is corresponded in the corresponding video file of intelligence event information as 2016- Video clip between 11-30-20-08-00 to 2016-11-30-20-15-22 is target video clip.
Optionally, searched targets video clip can specifically be implemented by the following steps：
The first step using playback duration o'clock as the first retrieval starting point, retrieves the 1st mesh from the video file of N number of channel Mark video clip.
The finish time of 1st target video clip is later than opening for the first retrieval starting point and the 1st target video clip Begin the moment earlier than or be later than the first retrieval starting point.
Second step retrieves starting point, from the video recording of N number of channel by i+1 of the finish time of i-th of target video clip I+1 target video clip is retrieved in file, i is the integer more than 0.
The finish time of i+1 target video clip is later than i+1 retrieval starting point and i+1 target video clip At the beginning of carve earlier than or be later than i+1 retrieval starting point.
Optionally, when target video clip is two or more, and target video clip belongs to same channels or not During with channel, need to detect target video file when whether belonging to same channel and the corresponding video recording of different target video clips Between section with the presence or absence of intersection, specific implementation refers to step 304 and step 305.
Step 304, detect i-th of target video clip and i+1 target video clip whether belong to same channel and For the corresponding video time section of the two there are intersection, i is positive integer.
The video time section of the target video clip of the same channel retrieved there may be intersection, such as：First object To be carved at the beginning of first object video clip at the time of face enters IPC coverages, first object face leaves IPC bats Finish time at the time of taking the photograph range for first object video clip；At the time of second target face enters the IPC coverages It is carved at the beginning of for the second target video clip, the second target face is recorded at the time of leaving the IPC coverages for the second target The finish time of photo section.Before first object face leaves the IPC coverages, the second target face is clapped into the IPC Range is taken the photograph, then the finish time earlier than first object video clip is carved at the beginning of the second target video clip, in this case First object video clip and the second target video clip video time section can there are intersections.
There is a situation where intersection for two target video clips in same channel, be that will not incite somebody to action in replayed section The video clip of intersection part repeats playback, it is therefore desirable to by step 305 by there are the records of the target of intersection in same channel Photo section merges.
Step 305, if belonging to same channel and the corresponding video time section of the two is there are intersection, i-th of target is recorded Photo section and i+1 target video clip merge.
I-th of target video clip with i+1 target video clip is merged, is carved at the beginning of obtained video clip It is start time one earlier in i-th of target video clip and i+1 target video clip, obtained video clip Finish time is finish time later one in i-th of target video clip and i+1 target video clip.
As another branch of step 304, if i-th of target video clip and i+1 target video clip do not belong to If in same channel or i-th of target video clip and i+1 target video clip belongs to same channel but the two is corresponding Intersection is not present in video time section, then directly performs step 306.
Step 306, target video clip is intercepted from the video file of corresponding channel.
The target video clip for not needing to merge can be intercepted directly, the target video film that needs are merged What section intercepted is the video clip after merging.
It is carved in a kind of possible realization method, at the beginning of the target video clip searched earlier than playback duration point, Then intercepted from the finish time of playback duration point to the target video clip.
Step 307, in playback interfaces by each target video clip according to affiliated channel in corresponding playback area It is played back in domain.
Playback interfaces include N number of playback region, and each channel corresponds to respective playback region.
Since each video file has a corresponding channel, the target video clip of interception is according to corresponding channel in correspondence Playback region in played back.
Optionally, in playback interfaces by each target video clip according to affiliated channel in corresponding playback region In the step of being played back, being substituted for as shown in Figure 3B：
Step 307a determines the playback sequence of each target video clip according to the sequencing of video time.
Step 307b is played back since the 1st target video clip in playback sequence.
Step 307c, if i-th of the target video clip and i+1 target video clip in playback sequence are in video recording Between on there are intersection, then the non-intersection part in i-th of target video clip and i+1 target video clip is played back to When, non-intersection part is individually played back in corresponding playback region according to affiliated channel；Playing back to i-th of target video clip During with intersection part in i+1 target video clip, according to affiliated channel by intersection part in corresponding playback area Domain synchronized playback, i are positive integer.
Step 307d, if i-th of the target video clip and i+1 target video clip in playback sequence are in video recording Between it is upper there is no intersection, then by i-th of target video clip according to affiliated channel behind corresponding playback region individually playback, then I+1 target video clip is individually played back according to affiliated channel in corresponding playback region.
In a kind of possible realization method, the time shaft of corresponding playback, when all channels on a timeline one section In all without target video clip in playback, skip this period, the nearest target record from any channel below It carves and is played back at the beginning of photo section.

It can be seen that in the intelligence playback for carrying out multichannel, it not only can be with multichannel quickly prominent intelligent event, but also can The mobile route of intelligent event is found out according to playback sequence.
In intelligent replayed section, when playback mode is switched to conventional playback mode by intelligent playback mode, it can incite somebody to action The playback file for only including the video clip with intelligent event information replaces with conventional playback file, specifically refers to step 308 to step 312.
Step 308, the second switching command is received.
Second switching command is used to indicate from intelligent playback mode and is switched to conventional playback mode.
Step 309, target video clip is closed.
It is the playback file closed in intelligent playback mode to close target video clip.
Step 310, it using the second playback moment when closing target video clip as retrieval starting point, retrieves in N number of channel A nearest video file for each channel.
Second playback moment referred to the correspondence moment that target video clip plays back on a timeline when closing video file.Due to Video before the second playback moment had played back, it is not necessary that video before is played back one again again Time, therefore the second playback moment was determined as the corresponding retrieval starting point of conventional playback mode.
It retrieves and is engraved at the beginning of a nearest video file retrieves video file after the second playback moment and with the Two playback moment were separated by nearest video file.
Step 311, when being carved at the beginning of a nearest video file earlier than the second playback moment, from the second playback moment Video file is intercepted.
If it is carved at the beginning of video file earlier than the second playback moment, by the video file from the second playback moment to record As the finish time of file is intercepted.
Step 312, in playback interfaces by a nearest video file for each channel in corresponding playback region Middle synchronized playback.
Under conventional playback mode, the video file of playback is not due to cutting the video clip with intelligent event information It is to be played back according to the rolling of time shaft, therefore can realize in corresponding playback region when taking out, therefore playing back In be carried out at the same time playback.
To being switched to intelligent playback mode by conventional playback mode in this present embodiment, can show in one shown in Fig. 3 E It is illustrated in the schematic diagram of the mode switching method of meaning property.Conventional playback mode is being switched to intelligent playback mode When, S301 is first carried out, closes the video file of current playback；Then S302 is performed, retrieval is next to be believed with intelligent event The video clip of breath；After the video clip with intelligent event information is retrieved, S303 is performed, judges the video film obtained Whether section needs to merge；If S303 judging results are yes, S304 is performed, merges video clip, then proceedes to perform S302；If S303 judging results are no, then perform S305, and video clip is intercepted according to intelligent event information, playback duration point；Most After perform S306, update playback file.
To being switched to conventional playback mode by intelligent playback mode in this present embodiment, can show in one shown in Fig. 3 F It is illustrated in the schematic diagram of the mode switching method of meaning property.Intelligent playback mode is being switched to conventional playback mode When, S307 is first carried out, closes the video file of current playback；Then S308 is performed, retrieves next conventional video file；So After perform S309, video file is intercepted according to the information of video file, playback duration point；S310 is finally performed, is updated Playback file.
At present in replayed section, it is for the video file generated after the playback function corresponding practical moment is opened It can not play back out, if when obtaining video file, newly-generated video file can be obtained, then can opening The video file generated after playback function can be come out by continuous playback, without reopening playback.Optionally, step 302 can be replaced by step 302a to step 302e as shown in Figure 3B.

It is carved at the beginning of the corresponding video file of playback duration point earlier than playback duration point or identical with playback duration point, and The finish time of the corresponding video file of playback duration point is later than playback duration point.
Step 302b after the video file is retrieved, obtains next video file.
After current video file has been retrieved, next video file is obtained, before next video file is likely to be After current video file the video file stored, it is also possible to be generated after playback function is opened Video file.
Step 302c when obtaining next video file failure, reacquires next video file again.
When obtaining next video file failure for the first time, may just there be new video file generation, therefore at once Next video file is obtained again, it can be to avoid interim card of the video file in replayed section.
Step 302d when reacquiring next video file failure again, detects whether exist every scheduled duration Next video file.
Scheduled duration is less than the refresh duration of video file.
Optionally, it detects whether there are next video file, that is, detecting index file corresponding with channel in hard disk is It is no to have refreshed, if index file has refreshed, it is determined that there are next video files.
Index file is used for the corresponding video file of unique mark, and index file includes at least the when long letter of video file Breath, channel information and intelligent event information.
Since the video file stored in hard disk refreshes once every certain time length, detect whether that there are next records As the interval scheduled duration of file is less than the refresh interval duration of video file, it will be able in the situation for thering is video file to generate Under, newly-generated video file can be added in playback file in time, can also be avoided in video file replayed section Interim card.Optionally, based on experience value, the interval scheduled duration of detection could be provided as 4 seconds.
If step 302e there are next video file, obtains next video file.
It, can be directly by newly-generated video file if getting newly-generated video file under conventional playback mode It updates in conventional playback file.But under intelligent playback mode, for the newly-generated video file got, need pair Video clip with intelligent event information is retrieved.
It, can be in a schematical video file update side shown in Fig. 3 G to updating video file in this present embodiment It is illustrated in the schematic diagram of method.S311 is first carried out, obtains next video file；Then S312 is performed, judges to obtain It whether takes without result；If S312 judging results are no, S316 is performed, updates playback file；If S312 judging results are yes, S313 is performed, is reacquired at once primary；It then proceedes to perform S314, whether judges to obtain without result；If S314 judging results It is no, then performs S316, updates playback file；If S314 judging results are yes, S315 is performed, by next time again detection time 4s is adjusted to, then cycle performs S313, S314, S315.
