[0079] Example implementations are now described with reference to the drawings; however, these implementations are merely examples of implementations and are not intended to limit the scope of what is described herein. For example, singular forms are intended to include the plural forms as well, unless the context clearly indicates otherwise. Furthermore, to the extent that the terms "includes," "containing," "has," "having," or variants thereof are used in either the detailed description or the claims, such terms are intended to be inclusive in a manner similar to the term "comprising." Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs. The materials, methods, and examples provided herein are illustrative only and are not intended to be limiting.

[0080] In addition, the drawings are only schematic and the dimensions of the various features are not necessarily to scale. Like reference numerals are intended to denote like parts throughout the various figures. Individual features can be labelled by the same reference numerals in different figures, in which case those features have the same or similar function(s). Some of the blocks in the drawings can be functional blocks that do not necessarily have a corresponding physical structure or implementation. These blocks can be implemented in software, hardware, firmware or any combination thereof. In some embodiments, some of the blocks can be implemented via one or more hardware modules or integrated circuits.

[0081] In a live streaming system, the video stream picture recorded by a camera needs to pass through some links from the camera to the terminal of the end user, such as a signaling service, a push streaming service, a cache service, a pull streaming service and the like; and the video stream picture will generate a delay at each link; therefore, displaying the flow path of the video stream picture and the time consumed between the links is beneficial to finding out the problem of the video stream picture at which link and the most consumed time; however, the prior art does not involve any solution for displaying the time delay of each link.

[0082] Based on this, the example embodiments of the present disclosure provide a display method of a time delay display result, which analyzes the flow path of a live stream and the delay size generated in each service by subscribing to the messages of a message queue through designing a service independently running; meanwhile, the display method of the time delay display result provided by the example embodiments of the present disclosure can also display the video service nodes through which the live stream flows by the points in the point-line and display the length of the delay by the length of the broken line in the point-line.

[0083] In an example embodiment, since the links passed through by different live streaming systems are not the same, a message queue needs to be introduced in the actual application process, and the mechanism of subscribing to the messages is used to achieve the purpose of separate design, so as to avoid the invasion of the original business; meanwhile, the point-line is dynamically generated, which can correspond to different service numbers and delays; in an example embodiment, the display method of the time delay display result recorded by the example embodiments of the present disclosure aims to design a simple and fast display of the business flow direction of the live stream and the time consumption between the services, so as to facilitate the user to intuitively see the dynamics of the video stream and improve the transparency of the underlying service to the outside; meanwhile, it is also convenient for the developer to troubleshoot problems and optimize the delay. And since the customer's requirement for live streaming delay is very high and very clear, but some delays in the actual application scenario are not caused by the links through which the live stream flows, such as the camera has a large delay when pushing the stream, the customer's playback end is improperly handled to cause a large playback delay and the like; under this premise, the display method of the time delay display result recorded by the example embodiments of the present disclosure can well solve the above problems; and through the point-line chart, the different business services through which the live stream flows and the delay time length in each service can be clearly seen, thereby enhancing the participation and experience of the user.

[0084] In an example embodiment, the display method of the time delay display result recorded by the example embodiments of the present disclosure can run on a server, a server cluster or a cloud server and the like; of course, the person skilled in the art can also run the method of the present disclosure on other platforms according to the requirement, which is not specially limited in the example embodiments. Specifically, referring to FIG. 1, the display method of the time delay display result can include the following steps:

[0085] Step S110. The video service node receives the topic message pushed based on the message push interface, and classifies the topic message to obtain a message classification result;

[0086] Step S120. The message classification result is sorted to obtain a time sequence of the target video stream when flowing through the video service node;

[0087] Step S130. The time delay display result of the target video stream in the video service node is generated according to the time sequence, and the time delay display result is displayed.

[0088] In the display method of the time delay display result, on the one hand, the topic message pushed by the video service node based on the message push interface is received, and the topic message is classified to obtain a message classification result; then the message classification result is sorted to obtain a time sequence of the target video stream when flowing through the video service node; finally, the time delay display result of the target video stream in the video service node is generated according to the time sequence; since the time delay of the video stream in each different video service node can be determined based on the time delay display result, the problem that the accuracy of the analysis result of the time delay reason is low due to the inability to determine the time delay of the video stream in each different video service node in the prior art can be solved; on the other hand, since the time delay display result can be directly displayed, the problem that the time delay of the video stream in each different video service node cannot be directly displayed in the prior art can be solved.

[0089] In the following, the display method of the time delay display result disclosed in the example embodiments of the present disclosure will be explained and described in detail in combination with the accompanying drawings.

[0090] First, the technical implementation principle of the example embodiments of the present disclosure is explained and described. Specifically, in the implementation process of the display method of the time delay display result provided by the example embodiments of the present disclosure, the following matters need to be noted: on the one hand, in the actual application process, when the video stream picture flows through multiple video service nodes, the data flow between the video service nodes is time-sequenced, but the video stream identification of the video stream picture (i.e. the target video stream) is not the same, so each video stream needs to be counted. The counted data can include but is not limited to service name, ID, inflow time, outflow time, module name, etc. On the other hand, the present disclosure relates to the display of the call chain, such as the service name and the module name within the service through which the live stream ID flows, and the page is drawn every time a live stream is accessed. At the same time, the time granularity of the present disclosure is millisecond, and the inflow and outflow granularity between the modules within the service requires to be finer. On the other hand, the present disclosure mainly counts the delay between services or modules, and the delay data needs to be updated in real time when flowing through the services or modules. Moreover, although the present disclosure does not involve the design and implementation of the streaming media service, nor the design and implementation of the player, when the delay data of the streaming media or the player needs to be displayed through the time delay display result provided by the present disclosure, the message push interface recorded in the present disclosure or the protocol conforming to the present disclosure needs to be introduced before it can be reflected on the page displayed by the present disclosure, that is, the call chain and real-time delay data of the accessed service or module.

[0091] In an example embodiment, the display method of the time delay display result recorded in the example embodiments of the present disclosure can include three parts: one part is message subscription; another part is ID dictionary and message time sequence array; and the other part is point line display data preprocessing array. Among them, the message subscription requires the integration of at least one common message queue service client SDK, which requires an adaptation layer to facilitate the extension of other message queues; the ID dictionary is used for the first classification of the received messages, each message has an ID belonging to which live stream, and this ID is the Key of the array; the time sequence array is the Value of the ID dictionary, and the messages entering the array need to be sorted according to the time they carry, which is convenient for subsequent business processing; the point line preprocessing array is a further business processing of the time sequence array, and the purpose is that after the array is called by the UI side, the point line chart and the service name and delay size through which the live stream flows can be drawn according to the data content in the array. Moreover, based on the above-mentioned three parts, it can be known that the present disclosure needs to focus on analyzing the delay problem in the field of video live stream, and through the intuitive chart display, it is convenient for the developer to troubleshoot the problem and for the user to understand the business service through which the live stream flows, which can also be integrated as a functional point into the user interface of the user for display.

[0092] In an example embodiment, the display method of the time delay display result disclosed in the example embodiment of the present disclosure can not only be used for analyzing the time delay reason of a video stream, but also be used for analyzing other time delay reasons, such as data processing time delay reason, communication time delay reason, data transmission time delay reason, model training time delay reason, alarm message transmission time delay reason, and the like, which are not specially limited in the present example; meanwhile, the display method of the time delay display result disclosed in the example embodiment of the present disclosure can achieve the pushing of the theme message by adding the message pushing business in the corresponding code, and then perform experimental analysis based on the theme message, so that the invasiveness of the whole scheme to the video processing system is extremely low. Further, taking the alarm message transmission time delay reason as an example, an alarm message is generated from an alarm system, and then pushed to a business distribution system, a notification system, a business processing system, and the like.

[0093] Secondly, the display system of the time delay display result involved in the example embodiment of the present disclosure is explained and described. Specifically, referring to FIG. 2, the display system of the time delay display result can include a message producer 210, a message queue 220, a message queue adaptation layer 230, a time delay analysis service 240, and a UI interface display 250. The message producer is in communication connection with the message queue adaptation layer, the message queue is in communication connection with the message queue adaptation layer, and the message queue adaptation layer, the time delay analysis service, and the UI interface display are sequentially in communication connection. The message producer refers to a service or a module that needs to be counted for delay collecting relevant state data at a specified position and pushing it to the message queue, and each service or module at least pushes 2 messages to identify the start and end points of the state; the message producer recorded herein is also a video service node; the message queue adaptation layer is an adaptation layer reserved for subsequent expansion of other message queue services, and a general interface is mainly defined in this layer, and the subscription, initialization, and the like of the message are all achieved by calling the interface to finally instantiate the message queue object; the main functions of the time delay analysis service can include but are not limited to: on the one hand, message queue configuration initialization, instance loading, and subscription of a specified TOPIC; on the other hand, the received message is deserialized and classified, such as an ID dictionary; on the other hand, the message is stored in the time sequence array of the ID dictionary in time sequence; on the other hand, the ID dictionary is traversed, and the time sequence array corresponding to each ID is formatted to generate a time sequence queue; the UI interface display can draw the UI according to the time sequence queue data taken from the time delay analysis service; and the specific session process is: calling the time delay analysis service to obtain the time sequence queue data; traversing the time sequence queue data and displaying it on the UI according to certain rules; and the message queue can be used to receive the theme message.

[0094] The display system of the delay display result disclosed by the example embodiments of the present disclosure firstly provides sufficient flexibility for adapting to user scenarios, and needs to be laid out in advance in terms of compatibility of the message queue; secondly, when defining the TOPIC and the message body of the message queue, a unified definition needs to be adopted and the exclusive purpose needs to be clear.

[0095] In the following, the specific generation process of the topic message will be explained and described in combination with FIG. 3. Specifically, referring to FIG. 3, the specific generation process of the topic message can include the following steps:

[0096] In step S310, the video stream identifier of the target video stream and the arrival time node of the video stream identifier received for the first time are found in the video service node, and the video stream identifier and the arrival time node are encapsulated to obtain a first message object.

[0097] In step S320, the departure time node of the video stream identifier from the video service node is found in the video service node, and the video stream identifier and the departure time node are encapsulated to obtain a second message object.

[0098] In step S330, the first message object and the second message object are serialized to obtain a topic message corresponding to the video service node.

[0099] In an example embodiment, the video stream identifier and the arrival time node are encapsulated to obtain the first message object, which can be implemented in the following manner: a start timestamp is generated according to the arrival time node, and the start timestamp, the video stream identifier, the unique node identifier of the video service node, and the node name are encapsulated to obtain the first message object.

[0100] In the following, the specific generation process of the topic message will be further explained and described. Specifically, the topic message disclosed herein has different topics in different application scenarios; for example, in the process of video stream pushing, the corresponding topic is the video stream topic; in the scenario of alarm message transmission, the corresponding topic is the alarm message topic. The topic message disclosed by the example embodiments can be divided into two parts: topic and topic message. The topic corresponds to the topic in different scenarios, and the topic message refers to the message generated by performing the corresponding operation under the topic. The example embodiments take the message generated in the video stream pushing scenario as an example for explanation and description.

[0101] Further, in the actual application process, before pushing the topic message, the message pushing interface in the video service node needs to be initialized first; then, the object identifier (i.e., the video stream identifier) and the first position receiving the video stream identifier are found and the message object S1 corresponding to the identifier is encapsulated, that is, the arrival time node of the video service node receiving the video stream identifier for the first time is determined, and then the video stream identifier and the arrival time node are encapsulated to obtain the first message object S1; further, in the process of encapsulating the video stream identifier and the arrival time node, first, the start timestamp is generated according to the arrival time node, and then the start timestamp and the video stream identifier, the unique node identifier and the node name of the video service node are encapsulated to obtain the first message object S1; similarly, the last position of the video stream identifier leaving the video service node is also found and the second message object S2 corresponding to the video stream identifier is encapsulated; in the specific encapsulation process of the second message object, first, the end timestamp can be generated according to the leaving time node, and then the end timestamp and the video stream identifier, the unique node identifier and the node name of the video service node are encapsulated to obtain the second message object S2; finally, the first message object S1 and the second message object S2 are serialized to obtain the topic message corresponding to the video service node, and the topic message is pushed to the message queue based on the message pushing interface deployed in the video service node. The specific structure of the message body of the topic message recorded here can be referred to FIG. 4.

[0102] It needs to be further supplemented here that in the actual application process, the video service node implements the specific message pushing process, and a message pushing interface is set to push the generated topic message to the message queue to generate the corresponding time delay display result.

[0103] In the following, the display method of the time delay display result shown in FIG. 1 will be further explained and described in combination with FIGS. 2-4. Specifically:

[0104] In step S110, the topic message pushed by the video service node based on the message pushing interface is received, and the topic message is classified to obtain a message classification result.

[0105] In the example embodiment, first, the receiving video service node receives the topic message pushed by the message push interface; specifically, the following method can be used: first, determine the video streaming path required for the target video stream from video generation to video playback, and determine the video service nodes included in the video streaming path; wherein the video service nodes described herein can include a push streaming service node, a cache service node, a pull streaming service node, a transcoding service node, and a video playback node; second, deploy the message push interface in the video service node, and receive the topic message pushed by the video service node based on the message push interface. That is, in actual application, in order to successfully receive the topic message pushed by the video service node, it is necessary to first deploy the message push interface in the video service node; specifically, the specific scene diagram of deploying the message push interface in the video service node can be referred to Figure 5. For example, in the example diagram shown in Figure 5, the message push interface can be deployed in the push streaming service node, the cache service node, the pull streaming service node, the transcoding service node, and the video playback node in sequence; wherein the message push interface is deployed in the video service node in the form of SDK (Software Development Kit). It should be noted that in actual application, different application scenarios correspond to different service nodes, and the example does not make special restrictions on this.

[0106] In an example embodiment, deploying the message collection component in the video service node can be implemented in the following manner: first, parsing the message queue receiving the topic message to obtain address information, token information and type information of the message queue; second, specifying the video service node that needs to execute the message push interface deployment according to the type information of the message queue; third, establishing a communication link between the video service node and the message queue based on the queue interface of the message queue; and fourth, sending the address information and the token information to the video service node based on the communication link, and deploying the message push interface into the video service node. Specifically, referring to FIG. 6, in actual application, in order to accurately deploy the message push interface into the corresponding video service node, first, the message queue needs to be configured and parsed, and the parsed results can include address information, Token (i.e. token information), type information, connection timeout time, and abnormal reconnection times of the message queue, etc. The address information is used to indicate the address of the message queue; the token information is used to indicate the verification information that needs to be carried when interacting with the message queue; the type information is used to indicate the type of the topic message that needs to be pushed; the connection timeout time is used to indicate that the video service node fails to push the topic message based on the message push interface when the time exceeds; the abnormal reconnection times are used to indicate that the video service node fails to push the topic message based on the message push interface when the number of reconnections exceeds; further, message queue adaptation is needed; and the specific adaptation process is to select the initialized specified message queue client (i.e. video service node) based on the type information of the message queue, establish the communication connection between the message queue and each video service node, and start a message receiving thread A in the message queue to receive the topic message pushed by the video service node.

[0107] In an example embodiment, receiving the topic message pushed by the video service node based on the message push interface can be implemented in the following manner: starting a message receiving thread in the message queue, and receiving the topic message pushed by the video service node based on the message push interface based on the message receiving thread. That is, in actual application, the message receiving thread A waits for the arrival of the topic message M after being started, and when the topic message M is received, it is pushed to the message service location of the message queue according to the specified TOPIC (DELAY_STATUS_MESSAGE), and then returns to the position of waiting for the message M to continue waiting, and the cycle is repeated.

[0108] Secondly, after receiving the theme message, the theme message can be classified to obtain a message classification result. Specifically, the classification process of the theme message can be implemented in the following way: firstly, the theme message is deserialized to obtain a target message object in the theme message; secondly, the theme message is classified according to the video stream identifier of the target video stream included in the target message object to obtain a message classification result.

[0109] In an example embodiment, the deserialization of the theme message to obtain the target message object in the theme message can be implemented in the following way: the theme message object is deserialized to obtain a first message object and a second message object in the theme message; the first message object and the second message object are fused to obtain the target message object; wherein the target message object includes a start timestamp, a terminal timestamp corresponding to a departure time node, a video stream identifier, a unique node identifier of a video service node, and a node name, etc. Specifically, since the theme message is obtained by serializing the first message object S1 and the second message object S2, in order to obtain the target message object, firstly, the first message object and the second message object in the theme message are deserialized, and then the first message object and the second message object are fused to obtain the target message object; at the same time, in the specific fusion process, since the difference between the first message object and the second message object is only the difference in the timestamp, the terminal timestamp can be directly merged into the first message object to obtain the target message object S3, or the start timestamp can be directly merged into the second message object to obtain the target message object S3, and this example does not make special limitation.

[0110] In an example embodiment, the message classification result is obtained by classifying the target message object according to a video stream identifier of a target video stream included in the target message object. The classification can be implemented in the following manner. First, validity of the target message object is detected to determine whether the target message object includes the video stream identifier of the target video stream. Second, when it is determined that the target message object includes the video stream identifier, a keyword of the video service node is determined according to the video stream identifier. Third, a value of the video service node is determined according to information other than the video stream identifier in the target message object, and a key-value pair of the video service node is constructed according to the keyword and the value of the video service node. Finally, the key-value pair is stored in a preset identifier dictionary, and key-value pairs with the same video stream identifier in the identifier dictionary are classified to obtain the message classification result. That is, in actual application, validity of the target message object needs to be detected first. Specifically, in the process of validity detection, the video stream identifier field (Trace ID) of the target message object can be directly extracted, and it is determined whether the video stream identifier field is empty. If it is empty, no further classification is performed. If it is not empty, classification can be performed directly based on the video stream identifier in the video stream identifier field. It should be noted that the target message object needs to be detected for validity because only when it is ensured that the target message object is valid (i.e., the target message object includes the video stream identifier), the subsequent classification process can be performed based on the video stream identifier, otherwise the specific classification process cannot be performed.

[0111] It should be further noted that the classification is performed to classify the first message object and the second message object with the same video stream identifier into the same dictionary corresponding to the video stream identifier. Meanwhile, in the process of classification, the number of classification results is consistent with the number of video stream identifiers.

[0112] In a possible example embodiment, when it is determined that the target message object is valid, a key-value pair corresponding to the target message object is generated, and the target message object is classified based on the key-value pair. That is, the video stream identifier field (Trace ID) can be stored as Key in the preset identifier dictionary, and other information can be stored as Value in the preset identifier dictionary. Value is an array with a variable length. The obtained message classification result can be specifically referred to FIG. 7.

[0113] In step S120, the message classification result is sorted to obtain a time sequence of the target video stream when flowing through the video service node.

[0114] Specifically, the message classification result is sorted to obtain the time sequence of the target video stream when flowing through the video service node, which can be achieved by extracting the unique node identifier in the key-value pair in the same message classification result, and sorting the key-value pair corresponding to the topic message based on the unique node identifier to obtain the time sequence of the target video stream when flowing through the video service node. Specifically, in the actual application process, since the positions of each video service node in the video stream path of the target video stream are fixed, and the node unique identifier of each video service node is also fixed and unique, the values in the key-value pair can be sorted directly based on the position of the video service node in the video stream path and the node unique identifier to obtain the time sequence; or the sorting can be performed according to the order of the start time stamp or the end time stamp in the message classification result, which is not specially limited in this example. The obtained time sequence can refer to FIG. 8. Of course, in the sorting process, the sorting process can be implemented based on the sorting thread in the message queue, and the corresponding time sequence can be generated.

[0115] In step S130, the time delay display result of the target video stream in the video service node is generated according to the time sequence, and the time delay display result is displayed.

[0116] In the embodiment of the present example, first, the time delay display result of the target video stream in the video service node is generated based on the time sequence. Specifically, the time delay display result of the target video stream in the video service node can be generated in the following manner: first, the time delay length of the target video stream when flowing through the video service node is calculated based on the start timestamp and the end timestamp corresponding to the video service node in the time sequence; and then, the time delay display result of the target video stream in the video service node is generated according to the time delay length, the video stream identifier, and the node name of the video service node. Specifically, the time delay display result of the target video stream in the video service node can be generated in the following manner: first, the length of the broken line corresponding to the video service node is determined according to the time delay length; second, the start point and the end point of the broken line corresponding to the video service node are determined according to the start timestamp and the end timestamp; then, the broken line corresponding to the video service node is drawn according to the length of the broken line, the start point, and the end point of the broken line, and the broken line is identified based on the video stream identifier and the node name to obtain the time delay display result of the target video stream in the video service node. That is, in the generation process of the time delay display result, first, the difference between the timestamps of the first message object and the second message object in the target message object is determined to obtain the time delay length of the target video stream when flowing through the video service node; then, the video stream identifier (Trace ID) is used as the unique identifier of each row of point broken lines, the start timestamp in the first message object and the end timestamp in the second message object in each video service node are used as the start point and the end point respectively, the time delay length is used as the length of the broken line between the two points, and the video service node is used as the name of each section of the broken line to generate the time delay display result. The obtained time delay display result can be referred to FIG. 9.

[0117] In an example embodiment, the length of the polyline corresponding to the video service node according to the time delay length can be determined by judging whether the time delay length is greater than a first preset length threshold, and when it is determined that the time delay length is greater than the first preset length threshold, a preset length value is used as the length of the polyline corresponding to the video service node; when it is determined that the time delay length is less than the first preset length threshold, the time delay length is used as the length of the polyline corresponding to the video service node. That is, in the process of generating the time delay display result, it can be first judged whether the time delay length is greater than the first preset length threshold; if it is greater than the first preset length threshold, a preset polyline length can be used to replace the time delay length as the length of the polyline corresponding to the video service node; otherwise, the time delay length is directly used as the length of the polyline. Of course, in the process of determining the length of the polyline, since the time delay length is in units of milliseconds, there can be a mapping relationship here, for example, one millisecond corresponds to one millimeter, or one centimeter, etc., which can be set according to actual needs in actual application, and the present example does not make special limitations thereto.

[0118] Further, after obtaining the time delay display result, the time delay display result can be displayed on the UI interface, so as to facilitate the developer or the operation and maintenance personnel to view the time delay display result.

[0119] Further, the video service node with abnormal delay can be located based on the delay display result, and the video service node with abnormal delay can be adjusted in performance. The video service node with abnormal delay can be located by the following method: extracting a longest broken line from the delay display result as a target broken line, and determining whether the length of the target broken line is greater than a second preset length threshold; when it is determined that the length of the target broken line is greater than the second preset length threshold, it is determined that the delay length corresponding to the target broken line is an abnormal delay, and the video service node corresponding to the abnormal delay is located. For example, the longest broken line can be extracted from the delay display result as a target broken line, and it is determined whether the length of the target broken line is greater than a second preset length threshold; when it is determined that the target broken line is greater than the second preset length threshold, it is determined that the delay length is an abnormal delay, and the video service node is located as an abnormal service node. It should be noted that it is necessary to determine whether the target broken line is greater than the second preset length threshold, because in some special cases, the delay length corresponding to the video service node is the longest, which may be within a reasonable delay range, so the video service node is not an abnormal service node. Of course, in another example embodiment, there can be multiple abnormal service nodes, and the lengths of the broken lines can be compared one by one to extract all broken lines greater than the second preset length threshold as target broken lines. In actual application, it can be determined according to actual needs, and the example does not make special limitations.

[0120] Further, in the process of adjusting the performance of the video service node with abnormal delay, the specific adjustment method can include but is not limited to adjusting bandwidth resources, adjusting memory resources, adjusting computing power resources, etc., and the example does not make special limitations. For example, assuming that the video service node with the longest delay is a transcoding service node, the memory resources and computing power resources of the transcoding server can be adjusted; for another example, assuming that the video service node with the longest delay is a player service node, the bandwidth resources of the terminal device corresponding to the player can be adjusted, etc.

[0121] In the following, the display method of the delay display result disclosed in the example embodiment of the present disclosure will be further explained and described in combination with FIG. 10. Specifically, referring to FIG. 10, the display method of the delay display result can be implemented based on the following method:

[0122] S1001, the video cloud initiates a GB28181 push stream instruction, which mainly includes SIP (Session initialization Protocol) protocol authentication, service port negotiation, etc. Specifically, the following methods can be used: when the signaling is initiated, an S1 message is generated; after the signaling verification is successful, an S2 message is generated, at which time the camera pushes the live stream T to the push stream server;

[0127] S1006, play service; specifically, the following methods can be used: when T is received, an S1 message is generated; after T is pushed to the player, an S2 message is generated;

[0128] S1007, message subscription; specifically, the following methods can be used: waiting to receive messages; message deserialization operation, classified into ID dictionary;

[0129] S1008, ID dictionary and time sequence queue;

[0130] S1009, UI display.
