The live broadcast list comprises a plurality of pieces of information, each piece of information represents a live broadcast room theme, each piece of information comprises a live broadcast id, a static cover picture and a live broadcast title, and the live broadcast titles and the static cover pictures are pre-configured by the anchor broadcast.
The anchor terminal 111, that is, the terminal device used by the anchor, may specifically be a personal computer such as a desktop computer and a notebook computer, and may also be a mobile phone, a tablet computer, a multimedia device, an intelligent wearable device, and the like, but is not limited thereto. The number of the anchor 111 may include one or more, fig. 1 shows the case where the number of the anchor 111 is plural, although the invention is not limited to the specific number of the anchors 111. In one embodiment of the present invention, a live mobile application is installed in the anchor terminal 111, and the anchor can create a live room in the live mobile application and perform live broadcasting.
The client 101, that is, the terminal device used by the user, may specifically be a personal computer such as a desktop computer and a notebook computer, and may also be a mobile phone, a tablet computer, a multimedia device, an intelligent wearable device, and the like, but is not limited thereto. The number of the clients 101 may be one or more, and fig. 1 shows the number of the clients 101, although the invention is not limited to the specific number of the clients 101. In one embodiment of the present invention, a live mobile application is installed in the client 101, and a user can watch live in the live mobile application.
The number of the execution servers 110 may be one, and certainly, in order to improve the execution efficiency and stability, there may be a plurality of execution servers 110, where a plurality of execution servers 110 form an execution server cluster, and the specific number of the execution servers 110 is not limited in the present invention.
Based on the live cover processing system 100 provided by the invention, live covers are processed, and the following is a working process of processing one live cover, specifically:
the client 101 sends a request for acquiring a live broadcast list to the cache server 102 by entering a locally installed live broadcast mobile application and triggering an interface for acquiring the live broadcast list, and the cache server 102 acquires the live broadcast list from the first storage device 103 and sends the live broadcast list to the client 101. The client 101 displays information of a live broadcast list on a screen, determines whether each piece of information meets a first condition, and if so, sends a live broadcast id corresponding to each piece of information meeting the first condition to the cache server 102, where the first condition is whether an area displaying the information is a preset position, and the preset position may be a central position of the screen or any position of the screen, which is not specifically limited in the present invention.
Next, the cache server 102 determines a live broadcast state of a live broadcast room corresponding to the live broadcast id according to the live broadcast information corresponding to the live broadcast id, determines a current live broadcast time of each live broadcast room if the live broadcast state is in live broadcast, searches a live broadcast dynamic graph meeting a second condition from the live broadcast information corresponding to the live broadcast id according to the current live broadcast time, and sends the live broadcast dynamic graph to the client 101. If the live broadcast state of the live broadcast room corresponding to the live broadcast id is live broadcast end, the cache server 102 searches a live broadcast end dynamic graph from the live broadcast information corresponding to the live broadcast id and sends the live broadcast end dynamic graph to the client 101. The client 101 replaces the static cover page of the information meeting the first condition with the corresponding live broadcast ending dynamic graph, and displays the live broadcast ending dynamic graph in a circulating mode. And if the information does not meet the first condition, continuing to display the information of the live list.
The second condition is that the live broadcast dynamic graph is a live broadcast dynamic graph related to the latest live broadcast time period before the current live broadcast time, and the live broadcast time period and the live broadcast dynamic graph are in one-to-one correspondence, so that the corresponding live broadcast dynamic graph can be determined by selecting the live broadcast time period. For example, the current live time is 11: 00: 30, the live time period before the current live time comprises 10: 59: 50-10: 59: 60. 11: 00: 00-11: 00: 10. 11: 00: 10-11: 00: 20 and 11: 00: 20-11: 00: 30, then the selected live time period is 11: 00: 20-11: 00: 30, if the current live broadcast time is 11: 00: 10, then the live time period is selected to be 11: 00: 00-11: 00: 10 corresponding to the live dynamic graph. And the client replaces the static cover page graph of the information meeting the first condition with the corresponding live broadcast dynamic graph, and circularly displays the live broadcast dynamic graph.
For example, after a user installs a mobile application at a home of a car at a client, and after logging in, the client 101 sends a request for obtaining a live broadcast list to the cache server 102 by triggering the online play interface, and after receiving the live broadcast list sent by the cache server 102, displays information of the live broadcast list on a screen, where fig. 2a to b are schematic diagrams of live broadcast list information. As shown in fig. 2a, 201 is a piece of information of the live list, the information includes a live cover and a live title, and the live cover of the piece of information is a static image because 201 is not located in the center of the screen. When the cover 201 is slid to the center of the screen, as shown in fig. 2b, the live cover is changed from the previous static cover to the dynamic cover. If the live broadcasting state of the live broadcasting room shown by 201 is live broadcasting, the dynamic graph at the moment is a live broadcasting dynamic graph, and if the live broadcasting state of the live broadcasting room shown by 201 is live broadcasting ending, the dynamic graph at the moment is a live broadcasting ending dynamic graph.
By the live broadcast cover processing system 100, the live broadcast cover is always the current live broadcast content in the live broadcast process, and a user can quickly judge whether the live broadcast content is interested or not by watching the live broadcast cover, so that the user experience is improved. On the basis, the dynamic graph corresponding to the most popular live broadcast content in the live broadcast room is used as a live broadcast cover after the live broadcast is finished, a user can determine whether the live broadcast content is interested or not by watching the live broadcast cover, the user experience is further improved, and the live broadcast cover is the most popular live broadcast content in the live broadcast process and can attract the attention of the user.
The live broadcast information of the present invention is generated in advance by the live broadcast id, the live broadcast state, and the streaming address in the live broadcast cover processing system 100 of the present invention, and the following is a working process of generating the live broadcast information of a live broadcast room:
the anchor 111 sends a request for creating a live broadcast room to the live broadcast server 106 and the cache server 102, and the live broadcast server 106 allocates a push stream address and a pull stream address to the anchor and sends the push stream address and the pull stream address to the anchor 111. After receiving the push stream address and the pull stream address, the anchor 111 sends the pull stream address to the cache server 102. The cache server 102 responds to a request of a main broadcasting end for establishing a live broadcasting room, distributes a live broadcasting id and a live broadcasting state for the main broadcasting end 111, sends the live broadcasting state to the main broadcasting end 111 in advance, establishes a piece of live broadcasting information for the live broadcasting room, stores the live broadcasting id and the live broadcasting state into the live broadcasting information, and stores a stream pulling address into the live broadcasting information after receiving the stream pulling address. The anchor terminal 111 finds a pre-established live broadcast room based on the live broadcast id, informs the cache server 102 to start live broadcast through the broadcast interface, and the cache server 102 responds to the broadcast notification of the anchor terminal 111 to update the live broadcast state in the live broadcast information to be live broadcast. In the live broadcasting process, the anchor terminal 111 sends the live broadcasting content to the live broadcasting server 106 through the stream pushing address, and the live broadcasting server 106 stores the live broadcasting content in the third storage device 107. When the anchor terminal 111 stops live broadcasting, the stream is stopped being pushed to the live broadcasting server 106, and a broadcast stop notification is sent to the cache server 102 through the broadcast stop interface, and the cache server 102 responds to the broadcast stop notification sent by the anchor terminal 111, and updates the live broadcasting state in the live broadcasting information to be live broadcasting end.
In the live broadcast process, the live broadcast dynamic graph as the live broadcast cover is dynamically generated according to the live broadcast content by a live broadcast dynamic graph generating system 200 composed of a cache server 102, a first storage device 103, a monitoring server 108, a scheduling server 109, an execution server 110, a picture audio server 104, a second storage device 105, a live broadcast server 106 and a third storage device 107 in a processing system 100 of the live broadcast cover in the live broadcast process, the live broadcast dynamic graph generating system 200 is shown in fig. 3, the cache server 102 in the system 200, the connection relationship among the first storage device 103, the monitoring server 108, the scheduling server 109, the execution server 110, the picture audio server 104, the second storage device 105, the live broadcast server 106, and the third storage device 107 is the same as that of the processing system 100 for live broadcast covers, and is not described herein again. In the live broadcasting process, the working process of the live broadcasting dynamic graph corresponding to one live broadcasting room, which is generated by the live broadcasting dynamic graph generating system 200, is as follows:
the cache server 102, in response to the request sent by the monitoring server 108 for acquiring the live broadcast information, reads the live broadcast information from the first storage device 103 and sends the live broadcast information to the monitoring server 108, where the monitoring server 108 sends the request for acquiring the live broadcast information to the cache server 102 at each time interval from the start of live broadcast to the end of live broadcast, and of course, the present invention does not limit the time interval, for example, 30 seconds, that is, the monitoring server 108 sends the request for acquiring the live broadcast information to the cache server 102 at every 30 seconds from the start of live broadcast to the end of live broadcast. The monitoring server 108 searches for a live broadcast id corresponding to the live broadcast information from the received live broadcast information, the live broadcast status of which is in live broadcast, and sends the found live broadcast id and live broadcast information to the scheduling server 109.
The scheduling server 109 then determines whether the task id exists in the live broadcast information, and if not (i.e., the task id is empty), allocates a task id to the found live broadcast id, selects an execution server 110 from the execution server cluster, and sends the found live broadcast id and the allocated task id to the selected execution server 110. If the task id exists in the live broadcast information, one execution server 110 is selected from the execution server cluster, and the found live broadcast id and the task id are sent to the selected execution server 110. In an embodiment of the present invention, the scheduling server 109 may select an execution server 110 from the execution server cluster through a preset rule, where the preset rule may be any method, for example, select the execution server 110 that has not been used for the longest time and has idle resources, and allocate the execution server 110 by way of polling, for example, the present invention is not limited to this, and all methods for selecting an execution server 110 from the execution server cluster are within the scope of the present invention.
Subsequently, the execution server 110 sends a request for obtaining the live broadcast information corresponding to the found live broadcast id to the cache server 102, and the cache server 102 reads the live broadcast information corresponding to the found live broadcast id from the first storage device 103 and sends the live broadcast information to the execution server 110. The execution server 110 determines whether the live broadcast state in the live broadcast information is in live broadcast, and if so, sends a request for acquiring a live broadcast content segment meeting a fourth condition to the live broadcast server 106 through accessing the stream pulling address, where the fourth condition is within a first preset time before the current live broadcast content, and of course, the present invention does not limit the first preset time, for example, the first preset time may be the first 10 seconds of the current live broadcast time. If the live broadcast state in the live broadcast information is live broadcast ending or previewing, the execution server 110 deletes the task id, deletes the task id of the live broadcast room of which the live broadcast state is live broadcast ending or previewing in this way, and can delete the task id in time, so that the resources of the execution server 110 are released, and the working efficiency of the task execution cluster is improved.
Next, the live broadcast server 106 acquires the address of the live broadcast content segment of the first 10 seconds of the previous live broadcast time and the live broadcast time period corresponding to the live broadcast content segment from the third storage device 107, and sends the address and the live broadcast time period to the execution server 110. The execution server 110 reads the live content segment by accessing the live content segment address, transcodes the live content segment into a live dynamic image, sends the live dynamic image to the picture audio server 104, and the picture audio server 104 stores the live dynamic image in the second storage device 105 and returns the live dynamic image url to the execution server 110.
In one embodiment, the execution server 110 generates a live middle dynamic graph, such as an ffmpeg tool, through a locally installed codec tool. In addition, because the original picture size and the proportion of the anchor terminal are different, if a live dynamic graph is directly generated according to the original proportion of live content and displayed to a user, the situation of irregularity can occur when the live dynamic graph is displayed, so that in order to solve the problem, the execution server 110 presets the width and the height of the dynamic graph in the coding and decoding tool and transcodes live content segments into the live dynamic graph with uniform size based on the preset width and height, and when the live dynamic graph is used as a live seal, the displayed picture size is uniform, so that the visual effect is more attractive, and the user experience is improved.
In one embodiment, the file format of the live dynamic graph includes webp, mp4, gif, and the picture audio server 104 may include a picture server and an audio server, both of which are connected to the CDN acceleration and can directly provide services to the outside. Accordingly, the second storage device 105 may also include a picture storage device and an audio storage device. When the file format of the live-broadcasting dynamic graph is mp4, the execution server 110 sends the live-broadcasting dynamic graph to the audio server, the audio server stores the live-broadcasting dynamic graph in the audio storage device, when the file format of the live-broadcasting dynamic graph is webP or gif, the execution server 110 sends the live-broadcasting dynamic graph to the picture server, and the picture server stores the live-broadcasting dynamic graph in the picture storage device.
Then, the execution server 110 associates the live dynamic graph url with the live time period, and sends the live id, the live dynamic graph url, and the live time period to the cache server 102, and the cache server 102 stores the live dynamic graph url and the live time period in the live broadcast to the first storage device 103 and in the live broadcast information corresponding to the live id.
The live broadcast middle dynamic graph generated through the process is generated in real time according to live broadcast content, the live broadcast middle dynamic graph serves as a live broadcast cover, a user can know the current live broadcast content by watching the live broadcast cover, and therefore the user can be helped to quickly judge whether the user is interested in the current live broadcast or not, user experience is improved, the user does not need to enter a live broadcast room to know the current live broadcast content, and user operation is simple and convenient.
In an embodiment of the present invention, after the execution server 110 reads the live content segment, it may also extract a key frame from the read live content segment, generate a picture from the extracted key frame, extract an audio from the read live content segment, and send the picture and the audio to the picture audio server. Wherein the picture audio server is further adapted to: and storing the picture and the audio to a second storage device, and returning the picture url and the audio url to the execution server. Specifically, the execution server 110 sends the picture to the picture server, and the picture server saves the picture to the picture storage device and returns the picture url to the execution server 110. The execution server 110 sends the audio to the audio server, which saves the audio to an audio storage device and returns an audio url to the execution server 110.
In one embodiment, in order to intelligently determine whether the live content is compliant, the live content is audited by the audit server 112, which includes the following steps:
the audit server 112 obtains the picture url, the audio url, and the live broadcast id from the execution server 110, obtains the picture and the audio by accessing the picture url and the audio url, and audits the picture content through a locally installed picture recognition tool, for example, whether the picture content has yellow identification (naked), advertisement (two-dimensional code, phone number), and the like, and if the picture content has the yellow identification (naked), a conclusion whether the live broadcast picture content is compliant is obtained. And the audio content is audited through a locally installed audio recognition tool, for example, whether the audio content has the phenomenon of identifying yellow (pornographic vocabulary) and abuse (unlubscribed language) or not is judged, and whether the live audio is in compliance or not is judged. And finally, summarizing the picture content conclusion and the audio content conclusion, for example, if any party in the pictures or the audio has non-compliant content, the live content is considered to be non-compliant. The audit server 112 sends the conclusion and live id to the execution server 110. The execution server 110 sends the conclusion and the live id to the cache server 102, and the cache server 102 stores the conclusion in the first storage device and the live information corresponding to the live id.
The intelligent examination and verification of the live broadcast content are realized through the content, and compared with manual examination and verification, the intelligent examination and verification method saves labor and improves working efficiency. And the picture and the audio are separately audited, and if one of the audio or the picture is not compliant, the live broadcast content can be determined to be not compliant, so that the auditing quality is improved.
And after the live broadcast is finished, a live broadcast finishing dynamic graph used as a live broadcast cover is determined according to a log generated when a user watches the live broadcast after the live broadcast is finished, the live broadcast finishing dynamic graph is one of all live broadcast middle dynamic graphs and is the most excellent content in all live broadcast middle dynamic graphs, and each live broadcast room only corresponds to one live broadcast finishing dynamic graph. The live broadcast ending dynamic graph is obtained by a live broadcast ending dynamic graph generation system 300 composed of the log server 113, the client 101, the cache server 102 and the first storage device 103 in the live broadcast cover processing system 100, the live broadcast ending dynamic graph generation system 300 is shown in fig. 4, and the connection relation among the log server 113, the client 101, the cache server 102 and the first storage device 103 in the system 300 is the same as that of the live broadcast cover processing system 100, and is not described herein again. The following is a working process of generating a live broadcast ending dynamic graph corresponding to a live broadcast room through the live broadcast ending dynamic graph generating system 300 after live broadcast ends:
the client 101 responds to the operation of the live broadcast mobile application installed locally by the user to trigger live broadcast watching, generates a log and sends the log to the log server 113. The log comprises a live broadcast id, a user identifier, reporting time and a user operation type, wherein the user identifier is a unique identifier of a user watching the live broadcast, the reporting time is a client local timestamp when the user reports the current log, and the operation type comprises watching, approval and gift sending. The log server 113 sets the second preset time as a time period, wherein the second preset time may be set according to actual needs, and the present invention is not limited, for example, 10 seconds. Counting log data of each time period according to the reporting time to obtain the number of watching persons, the number of praise times and the number of gift deliveries in each time period of the live broadcast room, and calculating the heat value of each time period of the live broadcast room according to the number of watching persons, the number of praise times and the number of gift deliveries, wherein the heat value is the welcome degree of live broadcast contents in each time period of the live broadcast room, is represented by the number of watching persons, the number of praise times and the number of gift deliveries in each time period of the live broadcast room, and is calculated according to the following calculation formula:
Figure RE-GDA0003132565050000191
wherein f (x) is the heat value of each time period, p0Based on the heat value, n is the operation type of the user in the live broadcast watching process, pnIs a statistic of operation type, anAnd the weight coefficient is corresponding to the statistic value of the operation type.
For example, the operation types of the user in watching the live broadcast include watching, praise, and delivering a gift, and the above formula can be expressed as:
f(x)＝p0+p1a1+p2a2+p3a3
wherein f (x) is the heat value of each time period, p0Based on the value of the heat capacity, p1The number of live viewers in the current time period, a1Weight coefficient of the number of people watching a live broadcast, p2For the number of praise of the current time period, a2Weight coefficient of the number of praise, p3The number of gift-giving articles in the current time period, a3Is the weight coefficient of the gift. p is a radical of0、a1、a2、a3May be set according to the actual situation, and the present invention is not limited to this. In one embodiment of the present invention, a1Is 1, a2Is 5, a3Is 10, base heat value p0Is 100.
For example, for a live broadcast room, the user log of the first 30 seconds in the live broadcast process is taken, for example, the live broadcast starts at 11 points, and then the time period of the first 30 seconds of the live broadcast is 11: 00: 00-11: 00: 30, taking 10 seconds as a time period, merging logs collected in the previous 30 seconds by taking 10 seconds as a unit according to a client local timestamp to obtain three units, wherein the three units are respectively: 11: 00: 00 unit, 11: 00: 10 units and 11: 00: 20 units, namely: 11: 00: 00-11: 00: 09 is classified as 11: 00: 00 unit, 11: 00: 10-11: 00: 19 is classified as 11: 00: 10 units, 11: 00: 20-11: 00: 29 is classified as 11: 00: 20 units. If at 11: 00: in unit 00, the log server 113 counts the received logs to obtain that the live broadcast room is in a range of 11: 00: there are 2 users watching in 00 unit, receiving two users to agree 3 times, sending 6 gifts, and a1Is 1, a2Is 5, a3Is 10, base heat value p0For example 100, then 11 for the live room: 00: the heat value at 00 time period is:
100+2*1+3*5+6*10＝177
and by analogy, the thermodynamic values of all time periods of the direct broadcasting room are obtained. Then, the log server 113 searches for the maximum heat value in each time period of the live broadcast room, and sends the live broadcast id, the maximum heat value, and the time period of the maximum heat value of the live broadcast room to the cache server 102. The cache server 102 searches the live broadcast time period corresponding to the time period with the maximum heat value from the first storage device 103, and takes the live broadcast dynamic graph associated with the live broadcast time period as a live broadcast ending dynamic graph. Specifically, the cache server 10 searches for a live broadcast time period overlapping with the time period of the maximum heat value from the first storage device 103, and if the live broadcast time period is found, takes a live broadcast in-progress dynamic graph url associated with the found live broadcast time period as a live broadcast end dynamic graph url. And if the live broadcast time period which is overlapped with the time period of the maximum heat value is not found, finding the next adjacent live broadcast time period of the maximum heat value from the live broadcast time period, and taking the live broadcast middle dynamic graph url corresponding to the next adjacent live broadcast time period of the maximum heat value as the live broadcast ending dynamic graph url.
For example, if the time period corresponding to obtaining the maximum heat value of a certain live broadcast room is 11: 00: 00-11: 00: 09, and the live time period comprises: 10: 59: 50-10: 59: 60. 11: 00: 00-11: 00: 10. 11: 00: 10-11: 00: 20 and 11: 00: 20-11: 00: 30, there is a time period 11 that overlaps with the time period corresponding to the maximum heat value: 00: 00-11: 00: 10, then the selected live time period is 11: 00: 00-11: 00: 10, taking the live time period as 11: 00: 00-11: 00: and 10, taking the live-in dynamic graph url corresponding to the live broadcast as a live broadcast ending dynamic graph url. If the live time period comprises: 10: 59: 50-10: 59: 60. 11: 00: 10-11: 00: 20. 11: 00: 20-11: 00: 30 and 11: 00: 30-11: 00: 40, there is no time period that overlaps the time period corresponding to the maximum heat value, then the next adjacent live time period to the time period of the maximum heat value is selected, i.e. the time period that is equal to 11: 00: 00-11: 00: 09 next adjacent live time period 11: 00: 10-11: 00: 20, with the live time period as 11: 00: 10-11: 00: and 20, the live-in dynamic graph url corresponding to the live broadcast is used as a live broadcast ending dynamic graph url.
