Detailed Description
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. 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.
In order to solve the problem of the prior art, embodiments of the present invention provide a method, an apparatus, and a system for automatically generating a video schedule. First, a detailed description will be given of an automatic video recording plan generation method according to an embodiment of the present invention.
It should be noted that the method provided by the embodiment of the present invention may be applied to a video cloud storage system, where the video cloud storage system is in communication with a front-end terminal set to generate a video plan, and the front-end terminal set may include a plurality of front-end cameras.
Furthermore, an execution subject of the method for automatically generating a video recording plan according to the embodiment of the present invention may be an automatic video recording plan generation apparatus. In a specific application, the video schedule automatic generation apparatus may be applied to a certain device in a video cloud storage system, where the device may be an existing device in the video cloud storage system, such as a storage server or a management server; of course, the device may also be a special device newly added in the video cloud storage system, such as: a dedicated cloud storage probe server, which is all reasonable.
Fig. 1 is a schematic flow chart of a method for automatically generating a video recording plan according to an embodiment of the present invention, where the method may include:
s101, sending a detection message to each front-end terminal in the front-end terminal set, wherein the detection message is used for detecting a flow taking parameter value corresponding to the front-end terminal.
When the video schedule generation condition is met, in order to acquire the streaming parameter values of each front-end camera, the video schedule automatic generation device may send a detection message to each front-end camera in the front-end camera group to detect and acquire the current streaming parameter values of each front-end camera in the front-end camera group.
It can be understood that the front-end camera group includes a plurality of front-end cameras, and each front-end camera corresponds to a unique identification information, such as an IP address, so that the plurality of front-end cameras can be divided into the front-end camera group according to the identification information of the front-end camera.
In order to enable the probe message to be safely and accurately sent to the front-end camera and enable the front-end camera to make feedback with respect to the probe message, in an embodiment of the present invention, the step of sending the probe message to each front-end camera in the front-end terminal set may include:
and sending a detection message to each front-end camera in the front-end camera set according to a preset network segment and a fixed port in each front-end camera.
In this case, all the front-end cameras in the preset network segment constitute the front-end camera set, and the video recording plan automatic generation device can send the probe information according to each IP address in the preset network segment, thereby ensuring that the probe information is sent to the front-end camera safely and accurately.
For example, if the pre-configured segment is an 10.192.1 segment, all front-end computers in the 10.192.1 segment are used as a front-end computer group, and probe messages are sent to the front-end computers with IP addresses of 10.192.1.1 to 10.192.1.255. Certainly, the preconfigured network segment may also include two network segments, and all front-end computers in the two network segments may be used as one front-end terminal set, for example, the preconfigured network segment includes 10.192.1 and 10.192.2 network segments, and then probe messages are sent to the front-end terminals with IP addresses of 10.192.1.1 to 10.192.1.255 and 10.192.2.1 to 10.192.2.255.
Of course, sending probe messages according to a pre-configured network segment is only an optional manner in the embodiment of the present invention, and does not constitute a limitation to the present application, and in the embodiment of the present invention, a front-end terminal corresponding to a plurality of IP addresses of different network segments may be preset as one front-end terminal group, for example, front-end terminals with IP addresses of 10.192.1.1, 10.192.1.2, 10.192.2.1, and 10.192.3.1 are used as one front-end terminal group.
After the front-end computer receives the probe message, the front-end computer needs to place the probe message on a port corresponding to a process for processing the probe message, so that the process obtains the probe message from the port corresponding to the process, and feeds back the probe message. That is, when the probe message is transmitted, a unified fixed port in the front-end camera receiving the probe message may be specified, for example, a unified fixed 5070 port may be used with reference to the GB21818 protocol, and the probe message received by any one front-end camera is transmitted to its internal 5070 port.
In the embodiment of the present invention, the automatic video recording plan generating device may send a probe message to each front-end terminal in the front-end terminal set, where the probe message may be a UDP (User Datagram Protocol) data packet, and the probe message may adopt an Extensible Markup Language (XML) format of a standard XML format of a Session Initiation Protocol (SIP). As will be appreciated by those skilled in the art, XML is a simple, platform-independent, and widely-used standard, and thus, the probe message in the embodiment of the present invention is in the XML standard, and has a wide versatility. Of course, the probe message may be other types of messages.
It can be understood that the probe message may carry stream fetching parameters to be obtained, such as version information of the front-end camera, a manufacturer of the front-end camera, a stream fetching protocol supported by the front-end camera, a user name/password of the front-end camera, a physical address of the front-end camera, and the like, and in order to ensure security of communication between the video recording plan automatic generation apparatus and the front-end camera, the probe message may also carry authentication information, such as KEY (KEY) information, for the front-end camera to authenticate whether the probe message is legal or not. Of course, the probe message may also carry information of the video recording schedule automatic generation apparatus, such as an address for receiving the response message, i.e. an IP address and a port of the device where the video recording schedule automatic generation apparatus is located, so as to ensure that the front-end camera sends the response message to the position specified by the video recording schedule automatic generation apparatus.
In addition, it should be noted that, when sending the probe message, different sending manners may be selected according to the authority of the node to which each front-end camera in the front-end terminal set belongs, for example, the probe message may be sent in a local area network according to the identifier information of the front-end camera included in the pre-configured front-end terminal set, or the probe message may be sent in a multicast manner in a wide area network, which is not limited in this embodiment of the present invention.
And S102, receiving response messages fed back by the front-end computers according to the detection messages.
In the embodiment of the present invention, a front-end monitoring module may be arranged in each front-end camera, and is configured to monitor the IP address and the port of the front-end camera, receive a detection message sent by the video schedule automatic generation apparatus to the monitored IP address and port, and feed back a response message to the video schedule automatic generation apparatus according to the detection message; accordingly, the video recording plan automatic generation device can receive the response message fed back by each front-end camera according to the detection message. It should be noted that, a port may be reserved in each front-end camera in advance, so as to facilitate interaction between the front-end monitoring module and the video schedule automatic generation apparatus.
The response message includes a stream fetching parameter value corresponding to the front-end camera, such as an IP address of the front-end camera, a monitoring port, version information of the front-end camera, a manufacturer of the front-end camera, a stream fetching protocol of the front-end camera, a user name/password of the front-end camera, a physical address of the front-end camera, and the like. For ease of management, the protocol of the reply message may be consistent with the protocol of the probe message, e.g., the reply message may be a standard XML-formatted message of the SIP protocol. Of course, the reply message may be other types of messages.
It can be understood that, when the front-end monitoring module in the front-end camera receives the probe message, if the probe message includes the authentication information for the front-end camera to identify whether the probe message is legal, the front-end monitoring module first needs to judge whether the probe message is legal, for example, perform KEY verification according to KEY information in the probe message, and if the verification passes, send a response message to the video schedule automatic generation device.
And S103, generating a video recording plan corresponding to each front-end terminal according to the streaming parameter values in the corresponding response messages.
In the embodiment of the present invention, after receiving the response message of the front-end camera, the automatic video recording plan generating device may generate the video recording plan corresponding to the front-end camera according to the streaming parameter value in the response message corresponding to each front-end camera.
As will be appreciated by those skilled in the art, video recording programs include: the stream fetching link and the stream fetching time are used for the cloud storage server to obtain video data in a time period corresponding to the stream fetching time from a front-end camera pointed by the stream fetching link, specifically, the stream fetching time is a time period set by a manager and used for obtaining the video data, and the stream fetching link is a URL (uniform resource locator) generated according to stream fetching parameter values of the front-end camera. Therefore, as an implementation manner of the embodiment of the present invention, a stream fetching link corresponding to each front-end terminal may be constructed according to a stream fetching parameter value in a corresponding response message; and generating a video recording plan corresponding to each front-end camera according to the corresponding stream taking link and the preset stream taking time.
It should be noted that, the automatic video recording plan generating apparatus extracts the value of the fetching parameter from the response message, and then constructs the fetching link according to the value of the fetching parameter, for example, the ID corresponding to the front-end camera in the fetching link may directly use the physical address of the front-end camera, or may be obtained by converting the physical address.
And the preset flow taking time can be set by a manager according to actual requirements. For example, for the front-end camera a, when it is desired to acquire video data within a time period of 10:00-12:00 a day, the preset time corresponding to the front-end camera a is 10:00-12:00 a day. The stream fetching time corresponding to different front-end cameras may be the same or different, and this is not limited in the embodiment of the present invention.
It can be understood that, since the video recording plan is a file with a specific format and containing the stream fetching link and the stream fetching time, after the stream fetching link corresponding to each front-end terminal is constructed, the constructed stream fetching link and the preset stream fetching time need to be generated into the video recording plan according to the specific format. Optionally, in order to improve the efficiency of generating the video recording plan, a video recording plan template with a specific format may be configured in advance, and after the stream fetching link corresponding to each front-end camera is constructed, the stream fetching link and the preset stream fetching time are directly written into the video recording plan template, so as to generate the video recording plan corresponding to each front-end camera.
As an implementation manner of the embodiment of the present invention, after the step of generating the video recording plan corresponding to each front-end camera according to the streaming parameter value in the corresponding response message, the method may further include: and issuing the generated video recording plans corresponding to the front end computers to a cloud storage server in the video cloud storage system. Therefore, the cloud storage server can automatically take the streaming video from each front-end camera according to the video plan. Specifically, the cloud storage server may obtain video data within a time period corresponding to a preset streaming time from a front-end camera pointed by a streaming link in the video recording plan.
The scheme provided by the embodiment shown in fig. 1 is explained below as a specific embodiment. As shown in the interactive diagram of fig. 2, first, the recording plan automatic generation device configures detection parameters, which specifically include: determining the IP address of each front-end camera in a front-end terminal unit to be detected, determining information such as stream taking parameters and the like carried in detection information, and then sending the detection information to the front-end camera by the video plan automatic generation device; after receiving the detection message, the front-end terminal determines the stream taking parameter values corresponding to the stream taking parameters carried by the detection message, and then sends a response message to the video plan automatic generation device; after the video plan automatic generation device receives the response message, parameters in the video plan template are configured, wherein the parameters in the video plan template comprise a stream taking link and stream taking time, and after the video plan automatic generation device constructs the stream taking link according to the stream taking parameter value in the response message, the stream taking link and the preset stream taking time are written into the video plan template, so that a video plan is generated. After the automatic video schedule generation device generates the video schedule, the video schedule can be issued to the cloud storage server, and the cloud storage server can take the streaming video from the front-end camera according to the video schedule.
As can be seen from the above, in the scheme provided in the embodiment of the present invention, the video cloud storage system communicates with the front-end terminal unit to generate the video plan, the video cloud storage system automatically detects the streaming parameter value of each front-end camera in the front-end terminal unit, and generates the video plan corresponding to each front-end camera according to the streaming parameter value in the response message fed back by each front-end camera.
As an implementation manner of the embodiment of the present invention, before generating the video recording plan corresponding to each front-end camera according to the streaming parameter value in the corresponding response message in step S103, the method may further include:
determining a target front-end camera from each front-end camera according to a preset target stream taking parameter value and a stream taking parameter value in a response message fed back by each front-end camera;
correspondingly, step S103 generates a video recording plan corresponding to each front-end camera according to the streaming parameter value in the corresponding response message, which may specifically be:
and generating a video recording plan corresponding to the target front-end camera according to the streaming parameter values in the response message fed back by the target front-end camera.
It can be understood that, because the number of front-end cameras included in the front-end terminal set is large, it is sometimes not necessary to generate a video recording plan for all the front-end cameras, but only a video recording plan for some specific front-end cameras, for example, a specific front-end camera may be a front-end camera of a specific type, such as a specific manufacturer, a specific device model, or a specific IP address, or may be a front-end camera of a combination of multiple specific types.
For example, the front-end terminal unit includes A, B, C front-end cameras of three manufacturers, when a video recording plan only needs to be generated for the front-end camera of manufacturer a, manufacturer a may be used as a preset target streaming parameter value, and after receiving a response message fed back by each front-end camera, the front-end camera including the streaming parameter value of manufacturer a in the response message is determined as the target front-end camera. And then, generating a video plan corresponding to the target front-end camera according to the streaming parameter values in the response message fed back by the target front-end camera.
For another example, the front end unit includes A, B, C three manufacturers and three front end cameras of a, b, and c streaming protocols, the manufacturer a and the streaming protocol a may be used as target streaming parameter values, and the front end camera that includes both the manufacturer a and the streaming protocol a in the response message is determined as the target front end camera.
It can be understood that, in the embodiment of the present invention, the target streaming parameter value is preset, and the front-end camera feeding back the response message is screened and filtered by using the target streaming parameter value to obtain the target front-end camera, so that the video recording plan of the target front-end camera requiring video recording can be flexibly and quickly generated.
Since the front-end computers in the front-end computer group may be changed, such as added, deleted, changed, and the like, and the video recording plans corresponding to the changed front-end computers should be changed accordingly to ensure the effectiveness of the cloud storage server in fetching the streaming video from the front-end computers, as an implementation manner of the embodiment of the present invention, the step S101 sending the probe message to each front-end computer in the front-end computer group may specifically be: periodically sending a detection message to each front-end terminal in the front-end terminal set;
correspondingly, the step S103 of generating a video recording plan corresponding to each front-end camera according to the corresponding streaming parameter value may include:
aiming at each front-end terminal feeding back the response message, judging whether the front-end terminal feeds back the response message aiming at the last detection message;
if not, generating a video plan corresponding to the front-end camera according to the streaming parameter value in the response message fed back by the front-end camera this time;
if yes, judging whether the current flow taking parameter value in the response message fed back by the front-end camera is changed relative to the reference information corresponding to the front-end camera; if the current feedback parameter value of the front-end camera changes, generating a video recording plan corresponding to the front-end camera according to the current feedback parameter value of the front-end camera, wherein the reference information corresponding to the front-end camera is the current parameter value of the front-end camera in the response message fed back by the front-end camera for the last detection message.
It can be understood that, in the embodiment of the present invention, in order to monitor whether each front-end camera in the front-end camera group changes, and ensure the effectiveness of the cloud storage server in fetching the streaming video from the front-end camera, the video plan automatic generation apparatus may periodically send the probe message to each front-end camera in the front-end camera group. For the response messages sent by each front-end camera received in each period, the video schedule automatic generation device can compare the response messages received in the previous period, if a certain front-end camera feeds back the response message for the detection message in the previous period, and does not feed back the response message for the detection message of this time, the fact that the front-end camera is not currently in communication connection with the video cloud storage system is indicated, at the moment, the existing video schedule of the front-end camera can be deleted, the cloud storage server does not need to take the streaming video from the front-end camera in the current period, and waste of network resources can be avoided.
For the front-end camera feeding back the response message this time, if the front-end camera does not feed back the response message for the detection message of the previous cycle, indicating that the front-end camera does not establish a communication connection with the video cloud storage system in the previous cycle, and the front-end camera establishes a communication connection with the video cloud storage system in the present cycle, a video recording plan corresponding to the front-end camera needs to be generated according to a streaming parameter value in the response message fed back by the front-end camera this time, so that the video recording plan is sent to the cloud storage server, and the cloud storage server can continue to take streaming video from the front-end camera.
For the front-end camera feeding back the response message this time, if the front-end camera feeds back the response message for the last detection message, it is also necessary to determine whether the streaming parameter value in the response messages fed back twice changes. If the current video is changed, the cloud storage server cannot obtain the streaming video from the front-end computer according to the video plan generated by the streaming parameter value in the response message fed back last time in the period. Therefore, a video recording plan corresponding to the front-end camera needs to be generated according to the current streaming parameter value fed back by the front-end camera.
As an implementation manner of the embodiment of the present invention, in a case that it is determined that the front-end terminal does not feed back a response message for the last probe message, the method may further include:
judging whether the front-end camera is a first front-end camera, wherein the first front-end camera is a front-end camera which does not feed back response messages in at least one continuous period;
if so, generating an additional recording task corresponding to the front-end camera according to the streaming parameter values contained in the response message fed back by the front-end camera this time, wherein the additional recording task is used for acquiring video data of the front-end camera within a time period to be additionally recorded, and the time period to be additionally recorded is determined according to at least one continuous period in which the response message is not fed back by the front-end camera.
It can be understood that due to a network interruption or the like, a certain front-end camera may not establish a communication connection with the video cloud storage system for at least one continuous period, and in order to acquire video data of the front-end camera in at least one continuous period in which the communication connection is not established, a complementary recording task corresponding to the front-end camera needs to be generated. Specifically, the recording task includes a streaming link and a time period to be recorded, and is used for the cloud storage server to acquire video data in the time period to be recorded from a front-end camera pointed by the streaming link, where the time period to be recorded is determined according to at least one continuous period in which no response message is fed back by the front-end camera, and the streaming link is a URL generated according to a streaming parameter value in a response message fed back by the front-end camera this time. And the supplementary recording task is issued to the cloud storage server, and the cloud storage server carries out supplementary recording on the video data in the time period to be subjected to supplementary recording of the front-end camera, so that the influence on the streaming video of the front-end camera due to network reasons can be avoided.
For example, the preset streaming time corresponding to the front-end terminal is 10:00-12:00 per day, and if the front-end terminal does not feed back a response message for 2 consecutive periods, when generating the logging task, the time period to be logged is 10:00-12:00 per day within the 2 consecutive periods.
Therefore, according to the scheme provided by the embodiment of the invention, the detection message is periodically sent to each front-end camera in the front-end camera set, and the video recording plan of each front-end camera is subjected to the operations of adding, deleting and modifying, so that the flexible management of the video recording plan and the additional recording task is realized.
It should be noted that, according to the scheme provided by the embodiment of the present invention, for a deployed video cloud storage system, in the maintenance processes of a large number of front-end cameras corresponding to the system, a newly-added front-end camera, and the like, manual operations can be reduced, and the maintenance efficiency can be improved. In addition, the scheme provided by the embodiment of the invention has good compatibility, when the video cloud storage system is deployed for the existing front-end terminal unit, a port for receiving the detection message can be reserved at each front-end terminal, and after the deployment and installation of the video cloud storage system are completed, the video plan automatic generation device realizes automatic interaction, issuing and management of the video plans for all the front-end terminals, so that the video cloud storage system is very convenient and fast.
