Embodiments of the present application will be described below with reference to the accompanying drawings. The embodiments described in the examples below do not represent all embodiments consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present application as detailed in the accompanying claims.

Example 1

Fig. 2 is a flow chart of a distributed camera implementation method according to an embodiment of the present application, and as shown in fig. 2, an execution subject of the present application is a distributed camera implementation device, where the distributed camera implementation device is located in a client. In the distributed camera implementation method provided by the embodiment, the client and at least one server access to the same local area network, the camera of each server is used as the distributed camera of the client, the client is provided with a client application, and each server is provided with a server application applied to the client, and the method comprises the steps 201 to 206.

Step 201, based on the ONVIF protocol, communicating with at least one server, and receiving server and distributed camera association information sent by at least one server.

In this embodiment, the client has a client application installed thereon. The server is provided with a server application and at least one camera. Wherein a camera can be understood as a video camera. The client and the server both support the ONVIF protocol, and the client and at least one server access the same local area network. The routing switch of the local area network supports multicast message forwarding.

The client may periodically send a multicast message in the lan based on the ONVIF protocol, searching for a server in the lan. The server side responds to the multicast message sent by the client side to communicate with the client side based on the ONVIF protocol, and sends the association information of the server side and the distributed cameras to the client side. The server and distributed camera association information may include: the streaming address of the server and the distributed camera identifications on the server.

Optionally, the server side and the distributed camera associated information may further include server side and distributed camera capability information, where the server side and the distributed camera capability information refer to functions supported by the server side and the distributed camera, such as, for example, supported resolution, coding mode, transmission protocol, whether the distributed camera can turn, whether audio can be collected, and the like. In a subsequent step, the client may determine configuration parameters, such as resolution, of the target video data stream based on the server and the distributed camera capability information. And the client-side control distributed camera function can be realized through an RTSP protocol.

The client can determine each distributed camera of the client according to the information related to each service end and the distributed camera, display each distributed camera in an interface of the client application, inform a user that a view finding picture of each distributed camera view angle can be obtained, and further realize the function of the distributed camera.

The client may filter out duplicate distributed cameras, remove offline distributed cameras, and update each distributed camera in the interface of the client application in real time during the periodic search.

In this embodiment, when the client and the plurality of servers access the same lan, the client and the plurality of servers may be connected to the same routing switch device. When the client and a service access to the same local area network, the service can start the hot spot, the client accesses to the hot spot of the service, and the client also starts the hot spot, and the service accesses to the hot spot of the client. The manner in which the client and at least one server access the same lan is not limited in this embodiment.

Step 202, determining video data stream acquisition interfaces corresponding to the distributed cameras according to the associated information of the distributed cameras and the service terminals.

In this embodiment, after the client obtains the information related to the server and the distributed camera based on the ONVIF protocol, the communication between the client and the server is disconnected, and the entity of the distributed camera of the client is located on the server, so when the user starts the target distributed camera, the client needs to establish a communication connection with the target server in order to obtain the view of the target distributed camera.

Therefore, after the client side obtains the relevant information of each server side and the distributed cameras, the client side can determine the video data stream obtaining interface corresponding to each distributed camera according to the relevant information of each server side and the distributed cameras. And when the video data stream interface is called, returning to the streaming address corresponding to the target distributed camera. Wherein the pull address may be a media plane pull address URI. The pull stream address includes the IP address of the target server.

Alternatively, the client may update the information associated with the distributed cameras by each server in real time during the periodic search. Since the same server exits after first accessing the lan, the IP address at the second re-access may be different from the IP address at the first access. Therefore, the change of the server-side streaming address will cause the streaming address of the distributed camera to change. The client can update the video data stream acquisition interface corresponding to the distributed camera according to the latest acquired service end and the distributed camera association information, so that the video data stream acquisition interface can return an accurate stream pulling address.

Step 203, receiving a target distributed camera starting request triggered by a user; the target distributed camera activation request includes a target distributed camera identification.

In this embodiment, after the client displays each distributed camera in the interface of the client application, the user may trigger the target distributed camera start request in the interface of the client application. For example, the client forms each distributed camera into an icon or list, and the user selects a target distributed camera by selecting information in the icon or list, triggering a target distributed camera activation request. The user may obtain the viewing angles of multiple distributed cameras by activating different distributed cameras.

Step 204, calling a target video data stream acquisition interface corresponding to the target distributed camera identifier, and establishing communication connection between the client and the target server based on an RTSP protocol; the target server is the server where the target distributed camera is located.

In this embodiment, the client may obtain the pull stream address of the target distributed camera by calling the target video data stream interface corresponding to the target distributed camera, and access the target pull stream address to establish communication connection with the target server.

Step 205, receiving a target video data stream of a target distributed camera sent by a target server based on the communication connection between the client and the target server.

In this embodiment, after the communication connection between the client and the target server is established based on the RTSP protocol, the client and the target server may communicate. Thus, the client may send a video data stream acquisition request to the target server, where the video data stream acquisition request includes the target distributed camera identification. Because the target distributed camera is a camera on the target server, the target server can start the target distributed camera after receiving the video data stream acquisition request, acquire the target video data stream of the target distributed camera, and send the target video data stream to the client. The target server side starts a target distributed camera, acquires an original video image acquired by the target distributed camera, encodes the original video image to obtain a target video data stream, and sends the target video data stream to the client side. The coding mode may be sent to the target server by the client based on the communication connection between the client and the target server.

Step 206, displaying the view of the target distributed camera on the user interface according to the target video data stream.

In this embodiment, the client may create a surface object and a player, and may decode the target video data stream with the player after receiving the target video data stream, to obtain real-time video data of the target distributed camera. The decoding mode corresponds to the encoding mode, and the target video data stream can be restored to the original video image. And the client draws the original video image into the surface object, so that a target camera framing picture is displayed on a client user interface. The Surface object Surface is a handle of an image buffer zone of the android system, and serves as a medium for interaction between the player and the View object View, and the player can draw a decoded image of the player to the View object View through the Surface object Surface. The View object View is a user interface control of the android system and is used for displaying images, and the player can display the images by taking the View object as a carrier of the images.

According to the distributed camera implementation method provided by the embodiment, the client and at least one server access the same local area network, cameras of all the servers are used as distributed cameras of the client, client applications are installed on the client, server applications are installed on all the servers and applied to the client, the client communicates with at least one server based on an ONVIF protocol, and information related to the distributed cameras and the server sent by the at least one server is received; determining video data stream acquisition interfaces corresponding to the distributed cameras according to the associated information of the distributed cameras and the service terminals; receiving a target distributed camera starting request triggered by a user; the target distributed camera starting request comprises a target distributed camera identifier; calling a target video data stream acquisition interface corresponding to the target distributed camera identifier, and establishing communication connection between the client and the target server based on an RTSP; the target server is the server where the target distributed camera is located; receiving a target video data stream of a target distributed camera sent by a target server based on communication connection between a client and the target server; and displaying a view of the target distributed camera on the user interface according to the target video data stream. The client acquires the relevant information of the server and the distributed cameras based on the ONVIF protocol, and determines video data stream acquisition interfaces corresponding to the distributed cameras according to the relevant relation of the server and the distributed cameras, and then when a user triggers a target distributed camera starting request, the client can directly call a target video data stream acquisition interface corresponding to the target distributed camera, establish communication connection with the target server, receive the target video data stream of the target distributed camera sent by the target server through the communication connection between the client and the target server, and then display a view finding picture of the target distributed camera on the user interface according to the target video data stream, thereby realizing the distributed camera of a pure application layer of a non-specific operating system.

As an optional implementation manner, on the basis of the first embodiment, the server side and the distributed camera association information include a pull stream address of the server side and each distributed camera identifier on the server side, and refine the step 202, and then the step 202 refinement includes steps 2021 to 2023.

In step 2021, the streaming address of the server where each distributed camera is located is determined as the streaming address corresponding to each distributed camera.

Step 2022, determining the pull stream address corresponding to each distributed camera as the return information when the video data stream acquisition interface corresponding to each distributed camera is called.

In this embodiment, the entity of the distributed camera is located on the server, so that the client needs to communicate with the target server to obtain the target video data stream. And determining the pulling address of the server where each distributed camera is located as the pulling address corresponding to each distributed camera, determining the pulling address corresponding to the distributed camera as the return information when the video data stream acquisition interface corresponding to the distributed camera is called, so that the video data stream acquisition interface corresponding to the target distributed camera returns to the pulling address of the target server when the video data stream acquisition interface corresponding to the target distributed camera is called, and the client can establish communication connection with the target server according to the pulling address corresponding to the target distributed camera, thereby acquiring the target video data stream from the target server.

According to the distributed camera implementation method provided by the embodiment, the information related to the distributed camera through the server side comprises a streaming address of the server side and identifications of the distributed cameras on the server side; determining the streaming address of the server where each distributed camera is located as the streaming address corresponding to each distributed camera; and determining the streaming addresses corresponding to the distributed cameras as return information when the video data stream acquisition interfaces corresponding to the distributed cameras are called. Because the streaming address of the server where the distributed camera is located is determined to be the streaming address corresponding to the distributed camera, and the streaming address corresponding to the distributed camera is used as the return information when the video data stream acquisition interface is called, the client can directly acquire the streaming address corresponding to the target distributed camera by calling the video data stream acquisition interface corresponding to the target distributed camera, which server the target distributed camera belongs to is not required to be determined, and the time for acquiring the target video data stream is saved.

Example two

Fig. 3 is a flow chart of a distributed camera implementation method according to a second embodiment of the present application, as shown in fig. 3, in the distributed camera implementation method according to the first embodiment, on the basis of the first embodiment, a target video data stream acquisition interface corresponding to a target distributed camera is called in step 204, a communication connection between a client and a target server is established based on an RTSP protocol, and refinement is performed, and then step 204 refinement includes steps 301 to 303.

Step 301, a target video data stream obtaining interface is called to obtain a target pull stream address corresponding to a target distributed camera.

In this embodiment, the client invokes the target video data stream acquisition interface and acquires a target pull stream address corresponding to the target distributed camera returned by the target video data stream acquisition interface. The target pull stream address may be a storage location of the target video data stream on the server side.

Step 302, a session establishment request is sent to the target server through the target pull address, and a transmission protocol, a client port number and a target service port number for communication with the target server are determined according to the RTSP protocol and the session establishment request.

In this embodiment, the session establishment request includes a transport protocol and a client port number. After receiving the session establishment request, the target server determines a port number for communication with the client in response to the session establishment request, and sends the target server port number to the client. The session establishment request may be a SETUP message in the RTSP protocol, and the session establishment request may further include a configuration parameter of the target video data stream, so as to instruct the target server to configure the parameter of the target video data stream, where the parameter of the target video data stream may be resolution, whether audio is carried, and so on.

Step 303, a session with the target server is established according to the transmission protocol, the client port number and the target server port number, so as to establish a communication connection with the target server.

In this embodiment, after receiving the port number of the target server, the client establishes a session with the communication with the target server according to the RTSP protocol, the transmission protocol, the port number of the client, and the port number of the target server, and prepares for transmission.

According to the distributed camera implementation method provided by the embodiment, the target streaming address corresponding to the target distributed camera is obtained by calling the target video data stream obtaining interface; transmitting a session establishment request to a target service end through a target streaming address, and determining a transmission protocol, a client port number and a target service port number communicated with the target service end according to an RTSP protocol and the session establishment request; establishing a session with a target server according to a transmission protocol, a client port number and a target server port number so as to establish communication connection with the target server; the RTSP is an application layer protocol and does not relate to an operating system, so that the function of the distributed camera can be realized on a non-hong operating system.

As an optional implementation manner, based on the second embodiment, the step 205 is further refined, and then step 205, based on the communication connection between the client and the target server, receives the target video data stream of the target distributed camera sent by the target server, where the refinement includes steps 401 to 402.

Step 401, sending a video data stream acquisition request to a target server through a session; the video data stream acquisition request comprises a target distributed camera identifier, and the video data stream acquisition request is used for indicating the target server to start the target distributed camera and acquiring a target video data stream of the target distributed camera.

Step 402, receiving a target video data stream sent by a target server.

In this embodiment, the video data stream acquisition request may be a PLAY message in the RTSP protocol. After the communication connection between the client and the target server is established successfully, the video data stream acquisition request is used for indicating the target server to acquire the target video data stream and sending the target video data stream to the client.

According to the distributed camera implementation method provided by the embodiment, a video data stream acquisition request is sent to a target server according to a session; the video data stream acquisition request comprises a target distributed camera identifier, and the video data stream acquisition request is used for indicating a target server to start a target distributed camera and acquiring a target video data stream of the target distributed camera; receiving a target video data stream sent by a target server; because the target recognition data stream is received, the view finding picture of the target distributed camera can be displayed according to the video data stream, and the distributed camera function can be realized.

As an optional implementation manner, based on any one of the foregoing embodiments, step 206 displays a viewfinder of the target distributed camera on the user interface according to the target video data stream, and then further includes steps 501 to 502.

Step 501, receiving a target distributed camera closing request triggered by a user; the target distributed camera close request includes a target distributed camera identification.
