Referring to fig. 2, fig. 2 is a schematic flowchart of a front-end camera real-time video-on-demand method according to an embodiment of the present application, where the method includes:

s201: and receiving an http real-time video on demand request sent by the traffic police terminal based on an http protocol, wherein the http real-time video on demand request carries a terminal identifier and a target camera identifier.

The traffic police terminal sends an http real-time video on demand request to the data server based on an http protocol, when the request is sent, a sender can be an internal person of a public security system and used for obtaining real-time videos of a monitored place and judging and processing illegal behaviors, and can also be a video on demand developer with access authority and used for on demand of the real-time videos of the front-end camera and debugging on demand parameters and on demand related equipment according to on demand responses. The http real-time video-on-demand request can be sent through a video monitoring platform which is developed independently, or can be directly sent through a web browser and received by a data server. The request under the http protocol is a one-way channel request from the traffic police terminal to the data server.

The http real-time video-on-demand request carries a terminal identifier and a target camera identifier, wherein the terminal identifier comprises an IP address and a port of the traffic police terminal, and the target camera identifier comprises an ID of a target camera.

S202: and generating an sip real-time video-on-demand request corresponding to the http real-time video-on-demand request according to the target camera identification, generating an http state identification corresponding to the http real-time video-on-demand request, an sip state identification corresponding to the sip real-time video-on-demand request, and synchronizing the identification contents of the http state identification and the sip state identification in real time, wherein the identification contents comprise an on-demand request overtime state and an on-demand request completion state.

After receiving the http real-time video on demand request, determining a target camera from front-end camera cluster information stored in a data server according to a target camera identification carried by the http real-time video on demand request, acquiring an access address of the target camera, and generating a request head in the sip real-time video on demand request according to the access address. And then, converting each on-demand command in the http real-time video on-demand request into an on-demand command under the sip protocol, generating the on-demand command into a message body in the sip real-time video on-demand request, and combining the request head and the message body to generate the corresponding sip real-time video on-demand request.

After the sip real-time video-on-demand request corresponding to the http real-time video-on-demand request is generated, corresponding http state identification and sip state identification are respectively generated for the http real-time video-on-demand request and the sip real-time video-on-demand request, wherein the identification contents of the two state identifications respectively comprise the starting time of the on-demand request, the expiration time of the on-demand request, the on-demand request overtime state and the broadcast request completion state. And synchronizing the identification contents of the http state identification and the sip state identification, namely, when the identification content of one of the http state identification and the sip state identification changes at any moment, the identification content of the other one of the http state identification and the sip state identification changes in the same way.

After the on-demand request is sent out, an on-demand response is usually returned within a short time, if the on-demand request is not processed for some reason, the on-demand response not only occupies the memory of the data server and causes resource waste, but also the request sender cannot respond late and causes poor user experience. Therefore, the identification content of the http state identification and the sip state identification comprises the start time and the expiration time of the on-demand request, the start time is used for marking the sending sequence of the on-demand request, the data server sequentially processes the on-demand requests according to the start time sequence of the on-demand requests, the expiration time can be the time obtained by adding a preset time value to the start time, when the on-demand request does not reach the expiration time, if an on-demand response is received, the on-demand request completion state in the identification content can show that the on-demand request is completed, and if the on-demand request does not reach the expiration time and no on-demand response is sent, the on-demand request timeout state in the identification content can show that the on-demand request is overtime. By setting an expiration detection mechanism in the data server, the request sender can be informed of the overtime state and the completion state of the on-demand request as soon as possible, so that the waste of processing resources can be avoided, and the user experience is improved.

S203: and determining a target camera and a target 5G base station corresponding to the target camera according to the target camera identification, determining long connection between the target camera and the target 5G base station, sending a sip real-time video on demand request to the target 5G base station through the long connection, so as to control the target 5G base station to send the sip real-time video on demand request to the target camera through a sip dedicated line based on a sip protocol, and receiving a sip processing signaling returned by the target camera through the sip dedicated line based on the sip protocol.

In a 5G scene, all front-end cameras in a certain area are correspondingly connected with a 5G base station, a one-to-many connection relation is formed between the 5G base station and the front-end cameras, and the connection relations are stored in a data server, so that a target camera corresponding to a target camera identifier can be determined according to the target camera identifier, and further the target camera can be determined to which 5G base station the target camera is connected, and the 5G base station is taken as the target 5G base station. And for all 5G base stations, long connection is established between the data server, after the target 5G base station is determined, the long connection between the data server and the target 5G base station can be found, and then the sip real-time video on demand request is sent to the target 5G base station through the long connection.

The long connection between the data server and the target 5G base station is transmitted based on a 5G protocol, and the sip real-time video-on-demand request is a request under the sip protocol, so that during transmission, the sip real-time video-on-demand request is firstly encapsulated into a first encapsulation packet and then is transmitted to the target 5G base station through the long connection, and the target 5G base station then unpacks the first encapsulation packet into the sip real-time video-on-demand request.

The target 5G base station is connected with the front-end cameras by a sip protocol, and each front-end camera is connected by a sip dedicated line to ensure the safety of data, so that after the target 5G base station receives a sip real-time video on demand request, the data server controls the target 5G base station to send the sip real-time video on demand request to the target cameras through the sip dedicated lines based on the sip protocol, and after the target cameras process the sip real-time video on demand request, the target cameras return a sip processing signaling through the sip dedicated lines.

S204: and receiving an sip processing signaling returned by the target 5G base station through the long connection, generating an sip real-time video on demand response according to the sip processing signaling, and synchronously updating the identification content of the sip state identification and the http state identification according to the content of the sip real-time video on demand response.

And after receiving the sip processing signaling, the target 5G base station returns the sip processing signaling to the data server through the long connection, and when returning, the target 5G base station encapsulates the sip processing signaling into a second encapsulation packet supporting the 5G protocol, and then unpacks the second encapsulation packet after receiving the sip processing signaling, so as to obtain the sip processing signaling.

And the data server generates an sip real-time video-on-demand response according to the sip processing signaling, and then synchronously updates the identification contents of the sip state identification and the http state identification according to the content of the sip real-time video-on-demand response. When the content of the sip real-time video on demand response is that the on demand is finished, the identification contents of the sip state identification and the http state identification are updated to be that the on demand request is finished, and when the content of the sip real-time video on demand response is that the on demand is overtime, the identification contents of the sip state identification and the http state identification are updated to be that the on demand request is overtime.

S205: and when the identification content of the http state identification meets the preset condition, generating an http real-time video on demand response corresponding to the http state identification.

After the identification content of the sip state identification and the identification content of the http state identification are updated, if the identification content of the http state identification meets a preset condition, the data server generates a corresponding http real-time video on demand response, and the response content of the http real-time video on demand response is the same as the response content of the sip real-time video on demand response. And when the identification content of the http state identification is one of the completion of the on-demand request and the overtime of the on-demand request, generating an http real-time video on-demand response corresponding to the http state identification.

S206: and returning an http real-time video on demand response to the traffic police terminal based on the http protocol according to the terminal identification.

After generating the http real-time video on demand response, determining a traffic police terminal sending the http real-time video on demand request according to the terminal identifier, then establishing an http session between the data server and the traffic police terminal, returning the http real-time video on demand response to the traffic police terminal, and determining whether the real-time video can be watched by the traffic police terminal based on the condition that the on demand in the received on demand response is finished or the on demand is overtime. When the on-demand is finished, the traffic police terminal can acquire the real-time video from the target camera, and when the on-demand is over time, the traffic police terminal can send the on-demand request again or analyze the reason of the over time, find out the reason of the over time and send the on-demand request again after the reason is solved.

It can be known from the above method that the front-end camera real-time video-on-demand method provided in the embodiment of the present application, first receives an http on-demand request sent by a traffic police terminal based on an http protocol, converts the http on-demand request into an sip on-demand request recognizable by a front-end camera, and synchronously generates a state identifier for the http on-demand request and the sip on-demand request, then sends the sip on-demand request to a target 5G base station through a long connection with the target 5G base station, controls the target 5G base station to send the sip on-demand request to the target camera, receives a sip processing signaling returned by the target camera, then returns the sip processing signaling based on the long connection, generates a sip real-time video-on-demand response, and synchronously updates the identifier contents of the sip state identifier and the http state identifier according to the contents of the sip real-time video-on-demand response, generates an http on-demand response and returns the http response to the traffic police terminal when the identifier contents satisfy a preset condition, and the traffic police terminal only needs to complete the whole on a web browser or a platform, and special SDK software is not required to be called, so that the safety is ensured, in addition, the information transmission is carried out through the 5G base station, the speed is higher, and the convenience for acquiring the traffic data and the illegal data is improved. In the protocol conversion process, the identification contents of the sip state identification and the http state identification are synchronized, so that the generated sip real-time video on demand response can be converted into the http real-time video on demand response in time, and the response returning speed is improved.

As shown in fig. 3, the framework of the front-end camera real-time video-on-demand is divided into several modules, and the data server includes http side processing logic 22, message synchronizer 23 and sip side processing logic 24. The http real-time video on demand request 21 sent by the traffic police terminal based on the http protocol is firstly sent to the http side processing logic 22 for processing, and then sent to the message synchronizer 23 by the http side processing logic 22; the message synchronizer 23 converts the http real-time video-on-demand request into a sip real-time video-on-demand request, generates an http state identifier for the http real-time video-on-demand request, generates a sip state identifier for the sip real-time video-on-demand request, synchronizes the identifier contents of the http state identifier and the sip state identifier, and then sends the sip real-time video-on-demand request to the sip side processing logic 24 for processing; after the processing by the sip side processing logic 24 is completed, the sip real-time video on demand request is sent to the target 5G base station 25 through the long connection between the target 5G base stations 25, the target 5G base station 25 sends the sip real-time video on demand request to the target camera 26, and receives the sip processing signaling returned from the target camera 26 to the target 5G base station 25, the target 5G base station 25 returns the sip processing signaling to the sip side processing logic 24 based on the long connection, the sip side processing logic 24 generates the sip real-time video on demand response according to the returned sip processing signaling and sends the sip real-time video on demand response to the message synchronizer 23, the message synchronizer 23 synchronously updates the identification content of the http status identification and the sip status identification according to the content of the sip real-time video on demand response, when the identification content of the http state identification meets the preset condition, generating an http real-time video on demand response and sending the http real-time video on demand response to the http side processing logic 22; the http side processing logic 22 returns an http real-time video on demand response 27 to the traffic police terminal, and the traffic police terminal determines the processing state of the on demand request according to the http real-time video on demand response 27.

As shown in fig. 4 and fig. 5, the http side processing logic 22 includes an http service module 221, a request parser 222, a validity judgment 223, an http message manager 224, and an http timer status notification queue 225, and the sip side processing logic 24 includes an sip on-demand management 241, an sip message manager 242, a user agent client 243, and a user agent server 244, and the front-end camera real-time video on demand method according to the present application is specifically described below with reference to fig. 4 and fig. 5.

And the traffic police terminal sends an http real-time video on demand request 21 to the http side processing logic 22, wherein the http real-time video on demand request 21 carries the target camera identification. The data server determines that a target camera is specifically located at xx road junction of xx road section of xx area according to a target camera identification so as to send http real-time video on demand request 21 to the target camera, and then determines to which terminal the on demand response and the real-time video stream are specifically sent after receiving the on demand response and the real-time video stream according to a terminal identification, so that a traffic police terminal can obtain the real-time video shot by the target camera, determine data such as traffic violation type, traffic violation time, information of traffic violation vehicles or pedestrians and the like according to traffic behaviors of vehicles or pedestrians at the junction in the real-time video, and can process the data according to the traffic violation data subsequently.

In the http side processing logic 22, the http real-time vod request 21 is received by the http service module 221, where the http service module 221 includes an http gateway, and then the http real-time vod request 21 is transferred to the request parser 222. The request parser 222 parses each command parameter in the http real-time vod request 21, and then puts the http real-time vod request 21 into the http message manager 224. The http message manager 224 continuously handles the internal message buffering while sending the newly entered http real-time vod request 21 to the message synchronizer 23.

In an embodiment, before the step of placing the http real-time video-on-demand request 21 into the http message manager 224, the validity judgment 223 is further performed on the parsed http real-time video-on-demand request 21, which specifically includes: based on the effective parameter set of the request for requesting, carrying out logic judgment on the http real-time video on demand request 21; and if the http real-time video-on-demand request 21 is legal, caching the http real-time video-on-demand request 21 into the http message manager 224, and if the http real-time video-on-demand request 21 is illegal, directly returning a termination request result to the traffic police terminal, wherein the termination request result is represented as an http real-time video-on-demand response 27 at the traffic police terminal. When the traffic police terminal sends the http real-time video-on-demand request 21, the http real-time video-on-demand request 21 is sent in a form of inputting a website on a web browser or a platform, the http real-time video-on-demand request 21 comprises parameters such as a target camera identification and an on-demand command, if the input of each identification or the on-demand command is wrong, subsequent processing logic is affected, therefore, after analysis, logic judgment is made on the http real-time video-on-demand request 21 based on an on-demand request effective parameter set, the on-demand request effective parameter set comprises types of effective parameters, specific parameter values, arrangement sequence of each parameter and the like, if the type is legal, the next step is entered, the http real-time video-on-demand request 21 is cached in the http message manager 224, if the type is illegal, a termination request result is returned to the traffic police terminal, and a specific error type can be further displayed, if the input is an invalid parameter or a corresponding target camera cannot be found, and the like, so that the http real-time video on demand request 21 can be adjusted and input again by the traffic police terminal.

In one embodiment, after the step of caching the http real-time vod request 21 to the http message manager 224, the method further comprises: judging whether the http real-time video on demand request 21 has the same content as the http real-time video on demand request entering in the previous preset time period; if the content is the same, the http real-time vod request 21 is removed from the http message manager 224, and if the content is different, the http real-time vod request 21 is sent to the message synchronizer 23. After the traffic police terminal sends the http real-time video-on-demand request 21, if no on-demand response is received within an expected time, one or more refreshing operations are usually performed, each refreshing operation re-sends one real-time video-on-demand request 21, the content of each sent real-time video-on-demand request 21 is the same, if the data server processes each request, resource waste is caused, therefore, after the http real-time video-on-demand request 21 is cached to the http message manager 224, the http message manager 224 numbers the incoming requests in time sequence, such as No. 1, No. 2, No. 3, and the like, and every time a new http real-time video-on-demand request 21 is entered, the incoming requests are checked for duplication and judged.

Assuming that the number of the newly entered http real-time vod request 21 is n, the http message manager 224 first determines whether an n-1 th request enters within a preset time period from the time of the n-th request entering, where the preset time period may be set according to the sending behavior of the majority of request senders, for example, if the majority of request senders start to initiate requests again if no response is received within 2 seconds after sending the request, 2 seconds may be used as the preset time period. If it is detected that no nth-1 request is entered within the previous preset time period, the newly entered http real-time vod request may be directly sent to the message synchronizer 23. If an n-1 request is detected to enter in the previous preset time period, content duplication judgment is carried out on the n-1 request and the n request, when the contents are the same, the n request is a repeated request, the newly entered http real-time video on demand request is removed from the http message manager 224, the n-1 request is continuously processed, when the contents are different, the n request is a new request, the newly entered http real-time video on demand request is sent to the message synchronizer 23, and after the n-1 request is processed, subsequent processing is continuously carried out on the n request.

After receiving the http real-time video-on-demand request 21, the message synchronizer 23 generates an sip real-time video-on-demand request corresponding to the http real-time video-on-demand request according to the identification of the target camera. The data server stores cluster information of the front-end cameras, the front-end cameras registered in the data server are all located in the cluster information, each front-end camera has a unique identifier, a target camera is determined from the cluster information of the front-end cameras according to the identifier of the target camera, an access address of the target camera is obtained, and a request head in a sip real-time video on demand request can be generated according to the access address. Then, converting each request command in the http real-time video-on-demand request 21 into a request command under the sip protocol, generating the request command into a message body in the sip real-time video-on-demand request, and combining the request header and the message body to generate the corresponding sip real-time video-on-demand request.

The message synchronizer 23 generates an http state identifier for the http real-time video-on-demand request 21, generates an sip state identifier for the sip real-time video-on-demand request, and synchronizes the http state identifier and the identification content of the sip state identifier in real time, wherein the identification content includes an on-demand request timeout state and an on-demand request completion state. In the message synchronizer 23, the identification contents of the http state identification and the sip state identification are the same at any moment, and the synchronization operation is realized by a corresponding synchronization program.

For the http real-time video on demand request 21 newly entering the message synchronizer 23, after the steps of format conversion and identification synchronization are completed, the sip real-time video on demand request is sent to the sip side processing logic 24, and then the sip side processing logic 24 sends the sip real-time video on demand request to the target camera corresponding to the target camera identification through the target 5G base station 25 based on the long connection with the target 5G base station 25. After the request is sent, the inside of the message synchronizer 23 detects the time-out and completion of the request, if the sip side processing logic 24 returns the sip real-time video on demand response, or if the sip real-time video on demand response does not return after exceeding the maximum value of the response time, the message synchronizer 23 generates a corresponding http real-time video on demand response and puts the http real-time video on demand response into the http timer state notification queue 225, the http timer state notification queue 225 notifies the http message manager 224 according to the sequence of response entering, the http message manager 224 returns the http real-time video on demand response 27 to the traffic police terminal, and the traffic police terminal can obtain the processing result of the request.

The sip real-time video-on-demand request is firstly sent to the sip on-demand management 241, and the sip on-demand management 241 generates a unique identifier for the sip real-time video-on-demand request and then caches the unique identifier into the sip message manager 242. Then, the user agent client 243 checks from the sip message manager 242 whether a new on-demand request arrives or an update of the on-demand request status is available, and sends a different request to the target 5G base station 25 according to the check result. When a new sip real-time video-on-demand request arrives at the sip message manager 242, according to the target camera identification carried in the sip real-time video-on-demand request, the target camera corresponding to the identification is determined, and then the 5G base station to which the target camera is connected is determined, and the 5G base station is used as the target 5G base station 25. For all 5G base stations, long connection is established between the base stations and the data server, after the target 5G base station 25 is determined, the long connection between the data server and the target 5G base station 25 can be found, and then the sip real-time video-on-demand request is sent to the target 5G base station 25 through the long connection.

In one embodiment, the specific step of sending the sip real-time video on demand request to the target 5G base station 25 includes: caching the sip real-time video-on-demand request into the sip message manager 242; encapsulating the sip real-time video-on-demand request into a first encapsulation packet; the first encapsulated packet is sent over the long connection to the target 5G base station 25. Because the long connection between the data server and the target 5G base station 25 is based on the 5G protocol transmission, and the sip real-time video-on-demand request is a request under the sip protocol, the sip real-time video-on-demand request is firstly encapsulated into a first encapsulation packet, then the first encapsulation packet is sent to the target 5G base station 25 through the long connection, and then the target 5G base station 25 unpacks the first encapsulation packet into the sip real-time video-on-demand request.

In one embodiment, the specific step of sending the sip real-time video on demand request to the target 5G base station 25 further includes: acquiring a connection period of a target 5G base station 25 and a target camera 26; and in the connection period, sending a sip real-time video on demand request to the target 5G base station 25 through the long connection so as to control the target 5G base station 25 to send the sip real-time video on demand request to the target camera 26 through a sip special line based on a sip protocol. The target 5G base station 25 and all front-end cameras in the connection range thereof form a one-to-many relationship, for each front-end camera, the target 5G base station 25 has a connection channel corresponding to the front-end camera, but the connection channels between the target 5G base station 25 and the front-end cameras are not communicated at all times, but are sequentially opened and closed according to a certain sequence, so that for each front-end camera, there is a corresponding connection period, and only in the connection period, the front-end camera and the target 5G base station 25 can realize communication, so that it is necessary to first obtain the connection period between the target 5G base station 25 and the target camera 26, and then in the connection period, control the target 5G base station 25 to send a sip real-time video-on-demand request to the target camera 26.

The target 5G base station 25 is connected with the front-end cameras by a sip protocol, and each front-end camera is connected by a sip dedicated line to ensure the safety of data, so that after the target 5G base station 25 receives a sip real-time video-on-demand request, the data server controls the target 5G base station 25 to send the sip real-time video-on-demand request to the target camera 26 through the sip dedicated line based on the sip protocol, and after the target camera 26 processes the sip real-time video-on-demand request, the sip processing signaling is returned to the target 5G base station 25 through the sip dedicated line.

And after receiving the sip processing signaling, the target 5G base station returns the sip processing signaling to the sip side processing logic 24 of the data server through the long connection, and the sip side processing logic 24 generates a sip real-time video on demand response according to the sip processing signaling and synchronously updates the identification contents of the sip state identification and the http state identification according to the content of the sip real-time video on demand response.

In one embodiment, the steps specifically include: receiving a second encapsulation packet returned by the target 5G base station 25 to the sip message manager 242 through the long connection, and unpacking the second encapsulation packet to obtain an sip processing signaling of the target camera 26; updating the identification content of the sip state identification corresponding to the sip real-time video on demand request in the sip message manager 242 according to the sip processing signaling; when detecting that the identification content of the sip state identification is that the on-demand request is overtime or the on-demand request is finished, generating and returning a sip real-time video on-demand response to the message synchronizer 23; and according to the content of the sip real-time video on demand response, synchronously updating the identification content of the sip state identification and the http state identification in the message synchronizer 23.

The processing signaling returned by the target camera 26 after processing the sip real-time video on demand request is sent to the sip side processing logic 24, and then received by the user agent 244, and the user agent 244 updates the identification content of the sip status identification corresponding to the sip real-time video on demand request in the sip message manager 242 according to the processing signaling. Specifically, when the processing signaling is 200OK, indicating that the on-demand request is completed, the user agent 244 matches the sip real-time video-on-demand request in the sip message manager 242, and updates the identification content of the sip status identifier corresponding to the sip real-time video-on-demand request to that the on-demand request is completed. If the processing signaling is 408, which indicates that the on-demand request has timed out, the user agent 244 will also match the sip real-time video-on-demand request in the sip message manager 242, and update the identification content of the sip status identifier corresponding to the sip real-time video-on-demand request to be timed out. In addition, the processing signaling return may also have other types, for example, 404 indicates that the user does not exist, 403 indicates prohibition, and the like, and the identification content of the corresponding sip state identifier is different after being updated according to the difference of the processing signaling.

When detecting that the identification content of the sip state identification is that the on-demand request is overtime or the on-demand request is finished, generating and returning a sip real-time video-on-demand response to the message synchronizer 23, and then synchronously updating the identification content of the sip state identification and the identification content of the http state identification in the message synchronizer 23 according to the content of the sip real-time video-on-demand response, so that the identification content of the sip state identification and the identification content of the http state identification are updated to be that the on-demand request is finished or the on-demand request is overtime.

In one embodiment, the steps after returning the sip real-time video on demand response to the message synchronizer 23 include: the sip real-time video-on-demand request is removed from the sip message manager 242. At this point the on-demand request has been processed and a corresponding on-demand response is generated, and therefore removed from sip message manager 242, the cache space of sip message manager 242 may be freed up to facilitate sip message manager 242 to re-process other request messages. In addition, after the removal, the data server can store a log related to sip real-time video on demand responses, classify a plurality of on demand responses within a certain period of time in the log, for example, classify according to overtime and completed conditions of on demand requests, analyze overtime conditions, find reasons, facilitate developers to perform BUG positioning and program debugging, and subsequently maintain and upgrade the system.

The message synchronizer 23 generates an http real-time video on demand response 27 corresponding to the http state identifier when the identifier content of the http state identifier meets a preset condition, where the preset condition is that the on demand request is completed or the on demand request is overtime. Specifically, when the identification content of the http state identification is that the on-demand request is overtime, generating an http real-time video-on-demand response 27 that the real-time video-on-demand is overtime; and when the identification content of the http state identification is that the video-on-demand request is completed, generating an http real-time video-on-demand response 27 that the real-time video-on-demand is completed.

And after generating the http real-time video on demand response 27, returning the http real-time video on demand response 27 to the traffic police terminal based on the http protocol according to the terminal identification. The message synchronizer 23 determines which port of which client the on-demand response should be sent to according to the terminal identifier, and then returns the http real-time video-on-demand response 27, and the traffic police terminal determines the processing result of the on-demand request according to the content of the http real-time video-on-demand response 27.

In one embodiment, the steps after returning the http real-time video on demand response 27 to the traffic police terminal include: the http real-time video-on-demand request and the sip real-time video-on-demand request are removed from the message synchronizer 23. After removal, the internal space of the message synchronizer 23 is also released to facilitate the message synchronizer 23 to process other request messages.

After the traffic police terminal obtains the http real-time video on demand response 27, the target camera 25 packages the shot real-time video stream, determines a stream receiving address according to the traffic police terminal IP address and the port information in the terminal identification, and then sends the real-time video stream to the traffic police terminal, and the traffic police terminal realizes the identification and subsequent processing of traffic violation data by watching the real-time video.

It can be known from the above embodiments that the front-end camera real-time video-on-demand method of the present application, first receives an http on-demand request sent by a traffic police terminal based on an http protocol, converts the http on-demand request into an sip on-demand request recognizable by a front-end camera, and synchronously generates a state identifier for the http on-demand request and the sip on-demand request, then sends the sip on-demand request to a target 5G base station through a long connection with the target 5G base station, controls the target 5G base station to send the sip on-demand request to the target camera, receives a sip processing signaling returned by the target camera, then returns the sip processing signaling based on the long connection, generates a sip real-time video-on-demand response, and synchronously updates the identifier contents of the sip state identifier and the http state identifier according to the content of the sip real-time video-on-demand response, generates an http response and returns the http response to the traffic police terminal when the identifier contents satisfy a preset condition, the whole on-demand process traffic police terminal can complete on a web browser or a platform, and in addition, the information transmission is carried out through the 5G base station, the speed is high, and the convenience for acquiring traffic data and illegal data is improved. In the protocol conversion process, the identification contents of the sip state identification and the http state identification are synchronized, so that the generated sip real-time video on demand response can be converted into the http real-time video on demand response in time, and the response returning speed is improved.

As shown in fig. 6 and 7, in actual operation, the traffic police terminal performs real-time video on demand by using a front-end camera on a platform, the platform is provided with a play video control 100 and a stop play control 200, wherein the play video control 100 corresponds to an on-demand interface, the stop play control 200 corresponds to a stop on-demand interface, when on-demand is required, the play video control 100 is clicked, then an http real-time video on-demand request is input in an input box 400 of a webpage popped up in fig. 7 and sent, and after an http real-time video on-demand response is received, a corresponding real-time video picture can be displayed in a video area 300 of the webpage in fig. 6. When the on-demand playing is required to be terminated, the playing termination control 200 is clicked, the on-demand request is input in the input box 400 of the popped-up webpage, and the playing of the real-time video can be terminated only by inputting the playing termination identifier in the on-demand request.
