Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. The components of embodiments of the present invention generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.
Thus, the following detailed description of the embodiments of the present invention, presented in the figures, is not intended to limit the scope of the invention, as claimed, but is merely representative of selected embodiments of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.
At present, the monitoring industry generally stores monitoring images of monitoring points shot by a network camera in a centralized manner so as to facilitate playback, when storage is performed, an iSCSI (SCSI transport protocol based on internet) connection is established between the network camera and a storage device, storage resources of the storage device are mounted to the local through the iSCSI protocol, then iSCSI protocol encapsulation is performed on stored video streams, and media and time index data are written into an IPSAN storage device by adopting a proprietary block storage format.
The block storage format mainly comprises a super block, a primary time index area, a data unit and a secondary time index area. The super block usually has dozens of K (such as 16K) bytes and is used for recording the version number of the block format and the camera code for shooting a monitoring point, a primary time index area is arranged behind the super block, each time index in the index area corresponds to one data unit one by one and is used for recording the storage time of the earliest frame in a frame group of video data of the data unit; the primary time index area is followed by a series of data units for storing video data for each frame group of the video recording. To ensure continuous writing of a frame of video data, the data unit typically amounts to several hundred mbytes (e.g., 256 mbytes). Each data unit starts with a secondary time index area, and each time index entry corresponds to a frame group of video data one by one and is used for recording the starting time of the frame group of video data.
The inventor finds that there are two block storage networking modes: one is that the network camera directly writes the video data into the storage device through ISCSI protocol, and the other front end IPC converges the storage stream to the data management server in the monitoring system, and the data management server writes the storage stream into the storage device. When the time jump of the network camera occurs, the video index written into the storage equipment is out of order, and when the time jump of the data management server occurs, all the videos written by the data management server also send the time jump. In addition, a file system is not arranged under a block storage format, so data is recorded in an index mode, indexes are cyclically overwritten according to a time sequence, and at present, when video retrieval and playback are carried out, an algorithm which is usually adopted is a dichotomy, so once time jump occurs, the dichotomy positioning is directly inaccurate when retrieval and playback are strongly dependent on time sequence in a video, and further, the retrieval result is inaccurate or the retrieval result cannot be obtained.
Therefore, it is an urgent technical problem to provide a video playing method capable of effectively avoiding the abnormal situations occurring in the retrieving and playback processes.

The video recording comprises a plurality of video data units, each index number corresponds to one video data unit, and the time jump information can comprise the index number before the time jump and the corresponding time point thereof, and can also comprise the index number before the time jump and the corresponding time point thereof after the time jump.
Step S110 may be to determine whether a time jump occurs according to a sequence of time points corresponding to each index number in the video index, and record time jump information when the time jump occurs.
In detail, in this embodiment, the video record and the record index are stored in a block storage format, and the record index includes a plurality of index numbers and time points corresponding to the index numbers, where the step S110 includes:
step S112: and acquiring an index number from the index numbers as a current index number, and comparing the time point corresponding to the current index number with the time point corresponding to the next index number adjacent to the current index number.
The manner of obtaining one index number from the plurality of index numbers as the current index number may be that, when a marked index number exists in the plurality of index numbers, the marked index number is used as the current index number. And when the marked index numbers do not exist in the plurality of index numbers, taking the index number with the minimum sorting sequence in the plurality of index numbers as the current index number.
It is to be understood that the marked index number may be the last index number when the last time the time jump information is detected, or may be any marked index number, and is not limited herein.
Step S114: and if the time point corresponding to the next index number is smaller than the time point corresponding to the current index number, obtaining time hopping information.
The time hopping information includes the current index number and a time point corresponding to the next index number and the next index number.
In order to obtain all the time jump information in the video index, after the step of S112 is performed, the method further includes:
and if the time point corresponding to the next index number is larger than the time point corresponding to the current index number, taking the next index number as a new current index number, and returning to execute the step of comparing the time point corresponding to the current index number with the time point corresponding to the next index number adjacent to the current index number until the next index number is the last index number in the video index.

and if the time point corresponding to the next index number is larger than the time point corresponding to the current index number, taking the next index number as a new current index number, and returning to execute the step of comparing the time point corresponding to the current index number with the time point corresponding to the next index number adjacent to the current index number until the next index number is the last index number in the video index.
All the time hopping information in the video index is obtained through the steps of the method.
It should be noted that, when the video recording and the video recording index are stored in the block storage format, a plurality of index numbers included in the video recording index may be stored in the primary time index region or the secondary time index region, and the index numbers are sequentially arranged from small to large in the primary index region or the secondary index region, and each index number corresponds to a time point. Each video data unit may include multiple frames of video data and may also include a group of frames of video data.
It is to be understood that, when the index number is an index number in the primary index area, the unit of video data corresponding to the index number includes a plurality of I frame group video data, and the time point corresponding to the index number is a time point corresponding to a starting I frame group video data in the plurality of I frame group video data, where the plurality of I frame group video data may be video data within one hour, video data within ten minutes, or video data within one minute. When the index number is an index number in the secondary index area, the video data unit corresponding to the index number includes an I-frame group video data, the time point corresponding to the index number is the time point of the start frame video data in the I-frame group video data, and one I-frame group video data may be video data within one minute or within one second.
Step S120: video playback information including a start time and an end time is obtained.
The manner of acquiring the video playback information may be to receive video playback information including a start time and an end time input by a user, or may be to acquire video playback information including a start time and an end time pre-stored in the memory 12, which is not specifically limited herein and may be set according to actual requirements.
Step S130: and splitting the video index according to the time hopping information to obtain at least two segment indexes, and retrieving each segment index according to the starting time and the ending time to obtain the segment index corresponding to the starting time and the segment index corresponding to the ending time.
The method for splitting the video index according to the time hopping information to obtain at least two segment indexes is as follows: and splitting the video index according to the current index number and the time point corresponding to the next index number and the next index number included in the time hopping information, so that the current index number and the next index number are located in different segment indexes.
It can be understood that when the acquired time hopping information is one, the obtained segment index is split into two segments, and when the acquired time hopping information is multiple, for example, n, the obtained segment index is split into n +1 segments.
The indexing of each segment index according to the start time and the end time may be performed by indexing each segment index according to the start time and the end time by a binary method.
The number of segment indexes corresponding to the start time obtained by performing the search by using the above-described bisection method may be one or more.
Step S140: and when the segment index corresponding to the starting time is more than 1, prompting a user to select a target starting segment index from the segment indexes corresponding to the starting time.
In this embodiment, the manner for prompting the user to select a target starting segment index from the segment indexes corresponding to the starting time may be: the segment indexes corresponding to the start times and the options corresponding to the segment indexes are displayed to the user through the display 16, so that the user can select the start time to be played back according to the selection items. It should be noted that, in order to facilitate the user to select the video to be played, in this embodiment, when the index after the time jump occurs in the segment index corresponding to the selection item, the selection item should also correspond to the time jump information, or information for prompting the user that the time jump occurs, for example, the information includes the corresponding time information before the time jump occurs or the information includes the word of the time jump, which is not limited specifically herein.
Step S150: and according to the target starting segmented index selected by the user, starting playing from a video data unit corresponding to the starting time in the target starting segmented index in the video record, and stopping playing when the video data unit corresponding to the ending time is played.
In addition, in this embodiment, it should be noted that, when the obtained segment index corresponding to the start time is one, the playing may be started from the video data unit corresponding to the start time in the video record in the segment index without the selection of the user, and the playing may be stopped when the video data unit corresponding to the end time is played.
According to the method, the video index is split based on the time corresponding to each index number in the video index to obtain the segmented index, the segmented index is searched by adopting a bisection method based on the starting time and the ending time input by a user to effectively guarantee the accuracy of obtaining the segmented index corresponding to the starting time and the accuracy of obtaining the segmented index corresponding to the ending time, the video is played from the video data unit corresponding to the starting time in the target initial segmented index in the video record based on the target initial segmented index selected by the user from the segmented index corresponding to the starting time, so that the effective and reliable retrieval and playback of the video are realized, and the problem that the video cannot be retrieved or the problem that the video is out of order when the video record is retrieved and played in the prior art is effectively solved.
In addition, when the segment indexes corresponding to the retrieved start and stop times are multiple, the video data corresponding to the start time without the time jump or the video data corresponding to the start time with the time jump can be played according to the requirement of the user.
In the present invention, the description will be given by taking the example that the index number is an index number in the primary index area, the video data unit corresponding to the index number includes video data of an I-frame group, and one I-frame group is video data within one half hour. As shown in table 1, the index is recorded from zero at 30 th of 4 months to five pm at 1 st of 5 months:
