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 reduce the complexity of video access, the embodiment of the invention provides a video access method, a video access device and a video access system.

First, a video access method provided in an embodiment of the present invention is described below from the perspective of a gateway device in a video access system.

It should be noted that, on the premise that the video access system provided in the embodiment of the present invention includes a cloud server, the video access system may further include at least one gateway device, and each gateway device is registered in the cloud server in advance. It is reasonable that the cloud server is program software deployed in a cloud server and used for providing a video access service, and the gateway apparatus is program software deployed in any type of electronic device, which may be referred to as an edge network device, and the electronic device may be a terminal device or a server. It can be understood that, through the cooperation of the cloud server and the gateway device, video pulling and management are performed on the video acquisition device, and a cloud-side-end integrated processing architecture can be formed.

Moreover, a plurality of video acquisition devices are registered in the cloud server in advance; after each video acquisition device is registered to the cloud server, the cloud server can establish a corresponding relationship between the video acquisition device and a registered gateway device, so that the corresponding relationship between the video acquisition device and the gateway device is obtained. Wherein, each gateway apparatus is configured with an SDK (Software Development Kit) for the corresponding video capture device, so as to log in the corresponding video capture device through the configured SDK, thereby performing various operations on the corresponding video capture device. It can be understood that each gateway apparatus is further configured with a corresponding relationship between the software development kit SDK of the corresponding video capture device and the device identifier, so that the SDK to be utilized can be determined subsequently based on the device identifier of the device to be operated. In addition, it will be understood by those skilled in the art that the SDK described above for any video capture device is provided by the video capture device vendor for use in operating the video capture device.

There may be a plurality of ways for establishing the correspondence between the video capture device and the gateway apparatus. For example, considering that each gateway apparatus may pull and manage a video stream for video capture devices belonging to the same lan, in an implementation, the establishing manner of the corresponding relationship between the video capture devices and the gateway apparatus may include: for each video acquisition device, determining a gateway device with the corresponding network address and the network address of the video acquisition device in the same address segment based on the network address of the video acquisition device and the network address corresponding to each gateway device, and establishing the corresponding relation between the video acquisition device and the determined gateway device; wherein, the network address corresponding to each gateway device is the network address of the device where the gateway device is deployed.

In addition, the process of registering each gateway device with the cloud server may include: sending a registration request to a cloud server, wherein the registration request carries a gateway ID of a gateway device, so that the cloud server registers the gateway device to the cloud server after receiving the registration request of each gateway device; and the gateway device can report heartbeat information to the cloud server after registering to the cloud server. The mode of registering each video acquisition device to the cloud server may include: the user logs in the cloud server through a login page of the cloud server, and device information such as network addresses and device identifications of corresponding video acquisition devices is added to the device list, so that the cloud server can store the device information of the video acquisition devices.

As shown in fig. 1, a video access method provided in an embodiment of the present invention is applied to a target gateway device in a video access system, and may include the following steps:

s101, determining target operation to be executed for target acquisition equipment;

in this embodiment, the target gateway device is any one of gateway devices in the video access system. The target acquisition equipment is video acquisition equipment corresponding to the target gateway device in a pre-established corresponding relation between the video acquisition equipment and the gateway device; each gateway device in the correspondence is configured with a software development kit SDK for the corresponding video capture device.

There are various ways in which the target gateway device determines the target operation to be performed for the target acquisition device. For example: when detecting that a pre-specified time point is reached or a specified trigger condition is met, the target gateway device determines a target operation to be executed for the target acquisition equipment according to a preset operation rule, wherein the number of the target acquisition equipment can be one or more. Another example is: after receiving a request of a cloud server, the target gateway device determines a target operation to be executed for the target acquisition equipment based on the request. For convenience of understanding, with reference to another embodiment, a specific implementation manner of the target gateway device is described later, after receiving a request of the cloud server, and determining a target operation to be executed for the target acquisition device based on the request.

In addition, there may be various kinds of target operations to be performed, for example: the target operation may be an operation for pulling a video stream, or an operation for disabling/enabling a device, or the like.

And S102, executing the target operation on the target acquisition equipment by using the SDK aiming at the target acquisition equipment.

After the target acquisition device executes the target operation by using the SDK for the target acquisition device, the target gateway device may report a response result for the target operation to the cloud server, so that the cloud server may store the response result, or output the response result to a user corresponding to the target acquisition device. Wherein, the response result to the target operation is a result obtained after the target operation is performed on the target acquisition device, which is as follows as an example: if the target operation is an operation for pulling the video stream, the response result is the video stream; if the target operation is the operation of the disable/enable device, the response result is result information for characterizing that the disable/enable device has succeeded or failed.

For example, performing the target operation on the target acquisition device by using the SDK for the target acquisition device may include:

Before logging in the target acquisition equipment, the target gateway device also needs the network address of the target acquisition equipment to locate the target acquisition equipment. In addition, the network address of the corresponding video acquisition equipment can be stored in the target gateway device in advance, so that after the target acquisition equipment is determined, the target gateway device acquires the network address of the target acquisition equipment from the local; or the network address of the corresponding video acquisition device is not stored in the target gateway device, and then, after the target acquisition device is determined, the target gateway device may obtain the network address of the target acquisition device from the cloud server based on the device identifier of the target acquisition device.

Optionally, in another embodiment of the present invention, as shown in fig. 2, a video access method applied to a target gateway device in a video access system may include the following steps:

s201, receiving an operation request aiming at target acquisition equipment issued by a cloud server;

s202, determining a target operation to be executed indicated by the operation request;

in this embodiment, after determining a target acquisition device to be operated and a target operation to be performed for the target acquisition device, the cloud server may determine, based on a correspondence relationship between a video acquisition device and a gateway device that is established in advance, the gateway device corresponding to the target acquisition device as a target gateway device, and issue an operation request for the target acquisition device to the target gateway device, where the operation request is used to instruct the target acquisition device to perform the target operation; correspondingly, the target gateway device may receive an operation request for the target acquisition device issued by the cloud server, and determine a target operation to be executed indicated by the operation request.

In order to enable the target gateway device to be able to locate the target acquisition equipment, if the target gateway device has previously stored the equipment identifier and the network address of the corresponding video acquisition equipment, the operation request may carry the equipment identifier of the target acquisition equipment; accordingly, after obtaining the operation request, the target gateway device may find the network address of the target acquisition device based on the device identifier carried in the operation request, so as to locate the target acquisition device. In order to enable the target gateway device to be able to locate the target acquisition equipment, if the target gateway device only stores the equipment identifier of the corresponding video acquisition equipment, the operation request may carry the network address and the equipment identifier of the target acquisition equipment; correspondingly, after obtaining the operation request, the target gateway device may obtain the network address of the target acquisition device from the operation request, so as to be able to locate the target acquisition device.

The specific implementation manner of the cloud server determining the target acquisition device to be operated and the target operation to be performed for the target acquisition device is described in detail later when the video access method is introduced from the perspective of the cloud server.

S203, executing the target operation on the target acquisition equipment by using the SDK aiming at the target acquisition equipment;

illustratively, the performing the target operation on the target acquisition device by using the SDK for the target acquisition device includes:

In this embodiment, S203 is the same as S102 in the above embodiments, and is not described herein.

And S204, feeding back a response result to the cloud server, wherein the response result is an execution result of the target gateway device executing the target operation.

After the target operation is executed to obtain the response result, the response result may be fed back to the cloud server, so that the cloud server may store the response result, or output the response result to a user corresponding to the target acquisition device.

In the scheme provided by this embodiment, the cloud server does not need to directly communicate with the video acquisition device, but the gateway device communicates with the video acquisition device, that is, the gateway device can serve as a transfer party of the cloud server, so that the difference of bottom hardware devices can be shielded for the cloud server, and the cloud server does not need to be adapted to each video acquisition device. Therefore, the complexity of video access can be reduced through the scheme.

Optionally, based on the embodiment shown in fig. 2, in another embodiment of the present invention, before the target gateway device receives the operation request for the target collection device sent by the cloud server, the following steps a1-A3 may also be included:

step A1, acquiring a state query request aiming at the target acquisition equipment and issued by a cloud server; the state query request is issued by the cloud server before the operation request is issued to the target gateway device;

step A2, acquiring the device state information of the target acquisition device from a local memory; wherein, the local memory records the device state information of the video acquisition device corresponding to the target gateway device;

step a3, feeding back the acquired device status information to the cloud server, so that when detecting that the device status information indicates an online status, the cloud server issues an operation request for a target acquisition device to the target gateway apparatus.

The device state information may represent an online state or an offline state, wherein the online state indicates that the video acquisition device is operating normally; while the offline state indicates that the video capture device is not operating properly. And the local memory is a memory of the device in which the target gateway apparatus is deployed.

In order to ensure the access effectiveness and prevent the target gateway device from accessing the target acquisition equipment which does not normally operate, the cloud server may first issue a status query request for the target acquisition equipment to the target gateway device before issuing the operation request to the target gateway device. Correspondingly, the target gateway device can acquire the equipment state information of the target acquisition equipment from the local memory; and feeding back the acquired equipment state information to the cloud server, so that the cloud server issues an operation request aiming at the target acquisition equipment to the target gateway device when detecting that the equipment state information represents an online state.

It can be understood that the target gateway apparatus may periodically collect the device state information of the corresponding video capture device based on the SDK for the corresponding video capture device, and store the device state information in the local memory. Therefore, the reliability of the equipment state information in the local memory can be greatly improved, and the data processing efficiency can be ensured.

In this embodiment, the cloud server does not need to directly communicate with the video capture device, but the gateway device communicates with the video capture device, that is, the gateway device can serve as a transfer party of the cloud server, so that the cloud server can shield the difference of the bottom hardware devices, and thus the cloud server does not need to be adapted to each video capture device. Therefore, the complexity of video access can be reduced through the scheme. And when the cloud server identifies that the target acquisition equipment is in an online state, the cloud server executes the step of issuing an operation request aiming at the target acquisition equipment to the target gateway device, so that the access validity can be ensured, and the target gateway device is prevented from accessing the target acquisition equipment which is not normally operated.

Optionally, in another embodiment of the present invention, the video access method applied to the target gateway device may further include:

periodically determining the storage information of the corresponding video acquisition equipment based on the SDK aiming at the corresponding video acquisition equipment, storing the storage information of the corresponding video acquisition equipment into the local memory, and reporting the storage information to the cloud server; wherein the stored information comprises at least device state information;

and after restarting, pulling the storage information of the video acquisition equipment corresponding to the target gateway device from the cloud server, and storing the storage information in a local memory.

In consideration of the instability of the local area network and the data reading speed, the storage information may be stored in a memory of the device in which the target gateway apparatus is deployed. Due to the storage in the memory, the stored information disappears when the power is off, and therefore, the target gateway device is in a stateless service. And the cloud server is a stateful service, and all data is persisted to the database, so that after the target gateway device is restarted, an information pulling request can be sent to the cloud server, and the data storage state before restarting is recovered. The storage information of any video capture device may further include a device identifier, video channel information, a network address, and the like of the video capture device.

Therefore, the scheme provided by the embodiment can reduce the complexity of video access, and can ensure that the data storage state before the restart can be recovered after the target gateway device is restarted.

The video access method provided by the embodiment of the invention is described from the perspective of a cloud server in a video access system. For the related descriptions of the cloud server and the gateway device in the video access system, reference may be made to the method embodiment described in the perspective of the gateway device, and details are not repeated here.

As shown in fig. 3, a video access method provided in an embodiment of the present invention may include the following steps:

s301, determining target acquisition equipment to be operated and target operation to be operated aiming at the target acquisition equipment;

when video access needs to be performed on the video acquisition device, the cloud server can determine the target acquisition device to be operated and the target operation to be executed on the target acquisition device according to a user instruction or a preset screening rule. The screening rule is used for indicating which devices are screened as target acquisition devices and which operations are screened as target operations.

It will be appreciated that a user may need to pull a video stream or disable/enable a device for a certain device, a certain acquisition area, or a certain device type, etc. Then, the user can log in the cloud server through the login page of the cloud server, so that an operation instruction is sent to the cloud server after the user logs in the cloud server; correspondingly, the cloud server can obtain the operation instruction, and further determine the target acquisition equipment to be operated and the target operation to be executed for the target acquisition equipment based on the operation instruction.

The operation instruction can be used for instructing target operation to be performed on a certain video acquisition device, at this time, the operation instruction can carry a device identifier of the certain video acquisition device and an operation identifier for indicating the target operation, and then the target acquisition device is the video acquisition device with the device identifier carried by the operation instruction; or the operation instruction may be used to instruct a target operation to be performed on a certain acquisition area, at this time, the operation instruction may carry an area identifier of the certain acquisition area and an operation identifier used to indicate the target operation, and then the target acquisition device is a video acquisition device in the acquisition area having the area identifier carried by the operation instruction; or, the operation instruction may be used to instruct to perform a target operation on a certain device type, where the operation instruction may carry a type identifier of the certain device type and an operation identifier used to indicate the target operation, and then the target acquisition device is a video acquisition device belonging to the type identifier carried by the operation instruction.

S302, determining a gateway device corresponding to the target acquisition equipment as a target gateway device based on a pre-established corresponding relation between the video acquisition equipment and the gateway device;

after determining the target acquisition device to be operated and the target operation to be performed for the target acquisition device, since it is necessary to assist the response operation by means of the gateway device corresponding to the target acquisition device, the gateway device corresponding to the target acquisition device may be determined as the target gateway device based on the correspondence relationship between the video acquisition device and the gateway device established in advance.

It can be understood that, after the video capture devices corresponding to the gateway apparatuses are determined, the device identifiers and the network addresses of the corresponding video capture devices may be issued to each gateway apparatus, so that each gateway apparatus can store the device identifiers and the network addresses of the video capture devices.

S303, issuing an operation request aiming at the target acquisition equipment to the target gateway device, wherein the operation request is used for indicating the target acquisition equipment to execute the target operation;

in order to enable the target gateway device to know which video acquisition equipment performs the target operation, if the target gateway device has previously stored the equipment identifier and the network address of the corresponding video acquisition equipment, the operation request may carry the equipment identifier of the target acquisition equipment; correspondingly, after obtaining the operation request, the target gateway device may find the network address and the SDK of the target acquisition device based on the device identifier carried in the operation request, log in the target acquisition device with the found network address by using the SDK of the target acquisition device, perform a target operation on the target acquisition device, and feed back a response result to the cloud service end.

In order to enable the target gateway device to know which video acquisition device performs the target operation, if the target gateway device only stores the device identifier of the corresponding video acquisition device, the operation request may carry the network address and the device identifier of the target acquisition device; correspondingly, after obtaining the operation request, the target gateway device may find the SDK of the target acquisition device based on the device identifier carried in the operation request, log in the target acquisition device having the network address carried in the operation request by using the SDK of the target acquisition device, perform a target operation on the target acquisition device, and feed back a response result to the cloud service end.

S304, receiving a response result fed back by the target gateway device; wherein the response result is an execution result of the target gateway device executing the target operation on the target acquisition device by using the SDK for the target acquisition device.

After receiving the response result, the cloud server may output the response result fed back by the target gateway device to the user. For example: if the target operation is an operation for pulling the video stream, the response result is the video stream; the target operation is the operation of the disable/enable device, and the response result is result information for characterizing that the disable/enable device has succeeded or failed.

Because the cloud server does not need to be in direct communication with the video acquisition equipment, but the gateway device is in communication with the video acquisition equipment, the difference of bottom hardware equipment can be shielded for the cloud server, and the cloud server does not need to be adapted to each video acquisition equipment. Therefore, the complexity of video access can be reduced through the scheme.

Based on the embodiment of fig. 3, as shown in fig. 4, a video access method applied to a cloud server according to another embodiment of the present invention may further include, before S303:

s305, acquiring the equipment state information of the target acquisition equipment; the device state information of the target acquisition device is detected and reported by the target gateway device based on the SDK aiming at the target acquisition device;

s306, detecting whether the equipment state information of the target acquisition equipment represents the online state, and if so, executing S303;

the device state information may represent an online state or an offline state, wherein the online state indicates that the video acquisition device is operating normally; while the offline state indicates that the video capture device is not operating properly. And the device state information of the target acquisition device is detected and reported by the target gateway device based on the SDK of the target acquisition device.

In order to ensure the access validity and prevent the target gateway device from accessing the target collection device which is not operating normally, before S303, the device state information of the target collection device may be first obtained, and different operations may be performed based on the information content indicated by the device state information. Specifically, when the device state information of the target collection device indicates the online state, S303 may be executed; when the device state information of the target acquisition device indicates the offline state, error reporting information indicating that the target acquisition device is in the offline state can be directly output to the user.

For example, in an implementation manner, the target gateway device may periodically collect device state information of the corresponding video acquisition device based on the SDK of the corresponding video acquisition device, and report the collected device state information to the cloud server, and accordingly, the cloud server may store the device state information reported by the target gateway device; then, before performing S303, the cloud server may obtain locally stored device state information of the target acquisition device. Through the implementation mode, the acquisition rate of the equipment state information is high, and the access delay is reduced.

For example, in another implementation manner, if the cloud server does not pre-store the device state information of the video capture device reported by the target gateway device, the obtaining the device state information of the target capture device may include:

and receiving the device state information of the target acquisition device fed back by the target gateway device.

After obtaining the status query request for the target acquisition device, the target gateway device may obtain the device status information of the target acquisition device from a local memory, and feed back the obtained device status information to the cloud server; the local memory records the device state information of the video acquisition device corresponding to the target gateway device. The local memory of the device to which the target gateway device belongs records the device state information of the video acquisition device corresponding to the target gateway device, so that the acquisition rate of the device state information is high, and the access delay is reduced. In addition, it can be understood that the target gateway device may periodically collect the device state information of the corresponding video capture device and store the device state information in the local memory, so that the reliability of the device state information in the local memory may be greatly improved.

Optionally, in another embodiment of the present invention, the above S303 may include the following steps:

issuing an operation request aiming at the target acquisition equipment to the target gateway device through a target calculation example; wherein the target computing instance is a processing procedure allocated to the target gateway device in advance.

Wherein, the so-called computing instance is a process, and a process can be referred to as a computing instance. Specifically, in order to ensure processing efficiency and improve throughput, a calculation instance may be allocated to each gateway device in advance, and further, an operation request for the target acquisition device may be issued to the target gateway device through a target calculation instance allocated to the target gateway device in advance.

After the target computing instance is distributed to the target gateway device, computing resources are distributed to the target computing instance according to a load balancing principle; accordingly, the target computing instance sends the operation request to the target gateway device based on the allocated computing resources. By way of example, computing resources may include, but are not limited to: a CPU and a memory. Moreover, when allocating the computing resource for any gateway apparatus, the number of the video capturing devices corresponding to the gateway apparatus may be considered, wherein the greater the number of the corresponding video capturing devices, the greater the computing resource. In addition, when the number of video acquisition devices corresponding to any gateway device is increased or decreased, the number of computing resources of the corresponding computing instance of the gateway device can be increased or decreased, so that the purpose of load balancing through dynamic resource allocation is achieved.

Additionally, there are a variety of ways to allocate a computing instance to any one gateway device. The following target gateway device is taken as an example, and a specific manner of allocating a computing instance is described as an example. In one implementation, the method for allocating the target computing instance to the target gateway device includes:

and after the target gateway device is registered to the cloud server, adding a computing instance as a target computing instance distributed for the target gateway device. With this implementation, the gateway device and the compute instance have unique correspondence.

For example, in another implementation, the manner of allocating the target computing instance to the target gateway device may include:

Through the implementation mode, each gateway device can correspond to one computing instance, and one computing instance can correspond to at least one gateway device, so that the excessive number of computing instances is avoided, and resource allocation and instance management are facilitated.

In the scheme provided by the embodiment, the cloud server does not need to be in direct communication with the video acquisition equipment, but the gateway device is in communication with the video acquisition equipment, so that the difference of bottom hardware equipment can be shielded for the cloud server, and the cloud server does not need to be adapted to each video acquisition equipment. Therefore, the complexity of video access can be reduced through the scheme. In addition, by allocating calculation instances in advance to the respective gateway apparatuses, it is possible to ensure processing efficiency and improve throughput.
