[0044] To make the objectives, 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 accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] The technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0046] During construction sites, it is often necessary to install surveillance cameras for construction monitoring. During different construction stages, multiple surveillance cameras from different manufacturers may be installed according to monitoring requirements. In the prior art, if one wants to monitor the video sources of the on-site construction progress, one can only log in to the specified camera address through a page for monitoring. When monitoring cameras from multiple manufacturers, it is cumbersome and time-consuming. Therefore, how to achieve unified management of the video sources collected by cameras from different manufacturers has become an urgent problem to be solved.

[0047] Based on the above problems, the embodiments of the present invention provide a video source management system, as Figure 1 shown. The video source management system includes: a gateway resource service 101 deployed on an industrial computer, a video stream service 102 deployed on a cloud server, a client 103, and multiple video source acquisition devices ( Figure 1 not shown in the figure). Among them, the gateway resource service 101 is used to obtain the device information corresponding to the video source acquisition device; assemble the pull stream address corresponding to the video source acquisition device based on the device information; when receiving a video call request of the video source acquisition device sent by the client 103, push the video source collected by the video source acquisition device to the video stream service 102 according to the pull stream address based on the video call request; the video stream service 102 is used to receive the video source pushed by the gateway resource service, store the video source, so that the client 103 can extract the video source for playback.

[0048] Among them, the above-mentioned industrial computer can be a hummingbird box or a server, etc. The above-mentioned video source acquisition devices include: cameras, network video recorders, etc. The present invention is not limited thereto. Exemplarily, in the embodiments of the present invention, the above-mentioned client 103 can be a platform such as a WEB platform for users to manage video devices.

[0049] It should be noted that, in the embodiments of the present invention, the used gateway resource service 101 is a gateway resource service developed using a software development kit (SDK), and the gateway resource service 101 uses the video stream push module in the ZlMediakit streaming media framework for push stream services.

[0050] Specifically, as Figure 2 shown, the gateway resource service 101 is used to execute steps S101 to S103. As Figure 3 shown, the video stream service 102 is used to execute steps S201 to S202. For the detailed working processes of the above gateway resource service 101 and video stream service 102, refer to the relevant descriptions in the method embodiments below, and details will not be elaborated here.

[0051] Through the collaborative cooperation of the above-mentioned various components, the video source management system provided by the embodiments of the present invention assembles the corresponding pull stream address by using the device information of different video source acquisition devices, and when a user requests to play the video source of the device, pushes the video source collected by the device to the video stream service according to the pull stream address. The user performs a pull stream display by calling back from the video stream service. The user only needs to perform a play operation to achieve the play of the video source of the corresponding device. The operation process is simple, improving the management efficiency of the video source, and is not restricted by the manufacturers and models of the video source acquisition devices, enabling unified management of different video source acquisition devices and improving the user experience.

[0052] The embodiments of the present invention also provide a video source management method, which is applied to the gateway resource service 101 and the video stream service 102 as Figure 1 shown. Among them, as Figure 2 shown, the gateway resource service 101 is used to execute steps S101 to S103. As Figure 3 shown, the video stream service 102 is used to execute steps S201 to S202.

[0053] Step S101: Obtain the device information corresponding to the video source acquisition device.

[0054] Specifically, the device information is the device-related information provided by the manufacturer corresponding to the video source acquisition device. Such as: username, password, IP address, port number, etc.

[0055] Step S102: Assemble the pull stream address corresponding to the video source acquisition device based on the device information.

[0056] Specifically, in the above step S102, the user name, password, IP address, and port number of the video source acquisition device are extracted from the device information; and the pull stream address corresponding to the video source acquisition device is assembled based on the user name, password, IP address, and port number. Exemplarily, the pull stream address is implemented based on the Real-Time Streaming Protocol (RTSP). The ports of each manufacturer are different, and the assembly formats are also different. Generally, it includes information such as device user name, password, IP, port, and channel number. Exemplarily, the pull stream address can be: rtsp: / / admin:admin@192.0.1.100:554 / Streaming / tracks / 101?starttime=20120802t063812z&endtime=20120802t064816z, but the present invention is not limited thereto. Thus, the pull stream address in the corresponding format can be assembled according to the device information corresponding to different devices, which is convenient for the subsequent unified management of the video sources collected by devices of different manufacturers.

[0057] Step S103: When receiving a video call request for a video source acquisition device sent by a client, push the video source collected by the video source acquisition device to the video stream service according to the pull stream address based on the video call request.

[0058] Specifically, in the above step S103, the target address of the video stream service is determined based on the video call request; the video call method in the video call request is obtained; and the video source collected by the video source acquisition device is pushed to the target address of the video stream service according to the pull stream address by using the interface corresponding to the video call method. Exemplarily, the video call methods include: live broadcast, playback, etc. For example, the user can click the live broadcast button on the client to call the live broadcast interface addPlayLive, obtain the video source collected by the corresponding device according to the pull stream address, and push the video source to the video stream service; the user can also click the playback button on the client to call the playback interface: addPlayBack, and push the video source to the video stream service. Thus, the management of different playback operations of the video source by the user is realized, the flexibility of video source management is further improved, and the user experience is enhanced.

[0059] Step S201: Receive the video source pushed by the gateway resource service.

[0060] Step S202: Store the video source so that the client can extract the video source for playback.

[0061] Specifically, the video stream service stores the received video source in the target address corresponding to the video call request, so that the user can extract the video source data of the video source acquisition device corresponding to the video call request from the target address. The user performs pull stream display through a callback on the client, and the whole process is completed with one-key operation, which is simple and smooth in terms of operation and visual experience.

[0062] By performing the above steps, the video source management method provided by the embodiments of the present invention assembles the corresponding pulling stream address by using the device information of different video source acquisition devices, and when a user requests to play the video source of a device, the video source acquired by the device is pushed to the video stream service according to the pulling stream address, and the user pulls the stream and displays it by calling back from the video stream service. The user only needs to perform a play operation to realize the play of the video source of the corresponding device. The operation process is simple, the management efficiency of the video source is improved, and it is not restricted by the manufacturers and models of the video source acquisition devices, and the unified management of different video source acquisition devices can be realized, improving the user experience.

[0063] Specifically, in one embodiment, the above gateway resource service 101 establishes the corresponding function service through the following steps:

[0064] Step S104: Obtain the SDK version information and initialize the SDK based on the SDK version information.

[0065] Specifically, by obtaining the SDK version glodon_iot_get_version; initializing the SDK glodon_iot_init: GatewayID is to set the gateway id, GatewayToken is to set the gateway token, MQTTHost, MQTTPort is to set the communication HostIp and port, and complete the initialization operation of the gateway.

[0066] Step S105: Establish a link relationship with the video stream service.

[0067] Specifically, establish a link relationship with the video stream service by starting the link server glodon_iot_connect.

[0068] Step S106: Register the device model based on the device information.

[0069] Specifically, register the device model glodon_iot_register_parser: on_gateway_message such as adding gateway information, on_nvr_message, on_camera_message such as adding device information such as network video recorders and cameras.

[0070] Step S107: Determine the pushing stream channel based on the link relationship.

[0071] Specifically, by initializing the global information init_global_data: adding camera data such as user password-related information, and then performing pushing stream channel management to determine the pushing stream channel for subsequent pushing to the video stream service.

[0072] Specifically, in one embodiment, the above video stream service 102 is further configured to perform the following steps:

[0073] Step S203: Monitor the play instruction corresponding to the video source.

[0074] Wherein, the play instruction includes: start play, pause play, end play and other instructions.

[0075] Step S204: Disconnect the connection with the gateway resource service and the client based on the relationship between the play instruction and the preset kick - off condition.

[0076] Wherein, the preset kick - off condition can be flexibly set according to the actual requirements of the user for video source management. In the embodiment of the present invention, the preset kick - off condition is that if the user pauses play for more than a certain time, then kick - off is executed.

[0077] Specifically, the above step S204 starts timing when the play instruction is a pause play instruction; when the timing duration is greater than the preset timing duration, it disconnects the connection with the gateway resource service and the client. For example: the client is the video stream being displayed; after the video stream service receives the user's pause operation, it starts timing as required, and disconnects the connection with the gateway resource service after N minutes, and at the same time disconnects the client connection.

[0078] Exemplarily, the specific implementation process of the above kick - off method is as follows:

[0079] 1) Add a thread: MointorClientStatus to the real - time status SrsStatistic of the video stream service;

[0080] 2) Add a stream array vector<StreamTime>vStreams to the thread;

[0081] 3) If the stream pauses play, then insert the array for timing vStreams.push_back(iStream)、getSystemTime();

[0082] 4) Traverse the stream array vStreams, and judge whether there is a client with stopped streaming (*iterStream).pStream->nb_clients == 1, and the time exceeds N minutes (*iterStream).t_now - (*iterStream).t_start)>N * 60;

[0083] 5) If so, kick off the client stream vStreams.erase(iterStream);

[0084] 6) Release resources iterClient->second->conn->expire().

[0085] The working process of the video source management method provided by the embodiments of the present invention will be described in detail below in combination with specific application examples.

[0086] Specifically, taking the client as a WEB platform, the streaming media range as an SRS server, and the video source acquisition device as a camera as an example, the above video source management process is as follows:

[0087] 1. Add camera-related information (such as user passwords) on the platform.

[0088] 2. Start the gateway video source service on the industrial control computer (which can be downloaded from the platform interface).

[0089] 3. The platform distributes all camera information.

[0090] 4. Click video playback on the platform: distribute the push stream address; the gateway video source service pushes the stream to the Srs server; the platform pulls the stream and displays it through the SDK callback.

[0091] 5. Pull the stream, stop the stream as required by the customer, and kick the stream if not watched for the default time interval.

[0092] In the embodiments of the present invention, the above video source management method is developed using the SDK based on the C++ development language. Through the transformation of the ZlMediakit streaming media framework server and the SRS server, the unified management of devices from various manufacturers is realized, and the unified management of video sources is achieved. The push and pull of video streams can be controlled; that is, real-time supervision can be carried out smoothly, and the stream can be kicked as needed in a timely manner.

[0093] By executing the above steps, the video source management method provided by the embodiments of the present invention assembles the corresponding pull stream address by using the device information of different video source acquisition devices, and when the user requests to play the video source of the device, the video source collected by the device is pushed to the video stream service according to the pull stream address. The user pulls the stream and displays it by calling back from the video stream service. The user only needs to perform a play operation to realize the playback of the video source of the corresponding device. The operation process is simple, the management efficiency of the video source is improved, and it is not restricted by the manufacturer and model of the video source acquisition device.
