In a live scene, the higher the popularity and the higher the ranking, the more likely the anchor is to be viewed by the user. The basic data of the popularity is the number of the live broadcast people, namely the number of the people determines the size of the popularity. However, in order to have higher popularity for some abnormal anchor, the popularity of people can be increased by abnormal means, so that the heat of the anchor itself is increased, and the fairness of live broadcast is greatly influenced. On this basis, the live broadcast platform will consume more resources to be able to complete when transcoding the video stream of the main broadcast. Namely, when the number of people in the live broadcast room is large, transcoding is automatically performed, so that the bandwidth of the CDN is reduced, and the purpose of transcoding is to reduce the code rate of a source stream, meet the viewing requirements of different clients in different networks, and reduce the bandwidth generated at the same time. That is, the transcoding strategy of the live broadcast room with higher popularity is more complicated, but if the live broadcast room is doped with popularity, more resources are consumed for transcoding, and therefore an effective solution is needed to solve the above problems.
Referring to a schematic diagram shown in fig. 1, determining access information of a room with a traffic-refreshing behavior by using a heartbeat statistical service, determining bandwidth information by using a content distribution network, then determining an abnormal score corresponding to the traffic-refreshing room by using a scheduling system according to the access information and the bandwidth information, representing an abnormal degree corresponding to the traffic-refreshing room by using the abnormal score, transcoding a video stream of the traffic-refreshing room according to a transcoding strategy corresponding to the abnormal score, completing transcoding processing of a source video stream by using different strategies for live broadcast rooms with different traffic-refreshing degrees, achieving the purpose of dynamically adjusting computing resources, and finally generating at least one play address corresponding to the traffic-refreshing room according to a transcoding result. The abnormal score corresponding to the brush measurement rooms is calculated through the access information and the bandwidth information, the accuracy of the abnormal score can be guaranteed, and on the basis, transcoding strategies are dynamically selected to transcode the brush measurement rooms with different abnormal degrees, so that computing resources are effectively saved.
On the basis, when the user watches the live broadcast, the corresponding playing address can be determined according to the access request of the user, so that the stream is pushed to the user according to the playing address, namely, the video stream corresponding to the definition in the watching request of the user is pushed, and the watching requirement of the user is met.
Fig. 2 is a flowchart illustrating a video stream processing method according to an embodiment of the present application, where the method is applied to a scheduling system, and specifically includes the following steps:
and step S202, acquiring access information and bandwidth information corresponding to the measurement room.
Specifically, the measurement brushing room specifically refers to a live broadcast room with measurement brushing behavior, and the live broadcast room may be any type of live broadcast room, such as a game live broadcast room, a gourmet live broadcast room, a science popularization live broadcast room, and the embodiment is not limited herein. Correspondingly, the volume swiping behavior specifically refers to a behavior of improving popularity of the live broadcast room by using an abnormal means, such as simulating a virtual user to access the live broadcast room, or accessing the live broadcast room through multiple devices under the same IP address. Correspondingly, the access information specifically refers to information including user information of an access counting room, an access address of a user, the number of people visiting the room and the like; accordingly, the bandwidth information specifically includes the bandwidth used by the measurement room, the bandwidth corresponding to the number of people, and the like.
Based on this, in order to accurately locate the abnormal degree corresponding to the measurement brushing room, resource adjustment can be performed according to the abnormal degree of the measurement brushing room, transcoding resources are saved, access information and bandwidth information corresponding to the measurement brushing room can be acquired first, and the abnormal degree of the measurement brushing room is determined according to a dual authentication mode of the access information and the bandwidth information.
Before the above, it is considered that the live broadcast platform bears more live broadcast rooms, normal rooms and measurement brushing rooms exist, and people corresponding to the normal rooms are visited by real users, so that the transcoding requirement of the normal rooms is determined by the number of the real users. And the transcoding demand in the measurement-brushing room is influenced by the measurement-brushing behavior of the abnormal user, so that the measurement-brushing room needs to be determined from a plurality of live broadcast rooms of the live broadcast platform, and then subsequent processing operation is performed, in the embodiment, the specific implementation mode is as follows:
acquiring user access information corresponding to a plurality of initial service rooms respectively; determining access equipment information corresponding to each initial service room according to the user access information; and comparing the access equipment information with reference access equipment information, and determining the brushing volume rooms in the plurality of initial service rooms according to the comparison result.
Specifically, the initial service room specifically refers to a plurality of live broadcast rooms in which the live broadcast platform is live broadcast; correspondingly, the user access information specifically refers to information corresponding to the access user in each live broadcast room, and includes, but is not limited to, device information, identity information, an IP address, and the like of the user. Correspondingly, the access device information specifically refers to information corresponding to a device where the user accesses the initial service room, and the information related to the terminal where the user watches the live broadcast room can be determined through the access device information. Correspondingly, the reference access device information specifically refers to access device information preset by the live broadcast platform, and is used for measuring whether the brushing behavior exists in each initial service room.
Based on this, since the live broadcast platform includes a plurality of initial service rooms, in order to be able to screen out the rooms having the traffic refreshing behavior, user access information corresponding to each of the plurality of initial service rooms may be obtained first, and access device information corresponding to each of the initial service rooms is determined according to the user access information, so as to determine the number of devices and the device type corresponding to each of the initial service rooms according to the access device information. At this time, the access device information is compared with the reference access device information, whether the volume refreshing behavior exists in each initial service room can be determined according to the comparison result, and finally, the live broadcast room with the volume refreshing behavior is selected to serve as the volume refreshing room, so that the subsequent transcoding resources can be conveniently adjusted.
In specific implementation, when the access device information is compared with the reference access device information, the device proportion in each initial service room is actually compared to determine whether the device proportion is similar to the real device proportion, so that the purpose of determining the brushing volume room is achieved.
In addition, the determination of the brushing amount room can also be realized by other manners, such as detecting whether the number of users belonging to the same IP address in the initial service room is greater than a threshold value, or detecting whether the ratio of the number of the bullets in the initial service room to the number of the visitors meets the threshold value, and the like. In practical applications, the detection mode of the brushing amount room may be set according to practical application scenarios, and the embodiment is not limited herein.
For example, user access information corresponding to a live broadcast room A and a live broadcast room B in a live broadcast platform are obtained, and the number of people watching live broadcasts in the live broadcast room through android system equipment is Ra1, the number of people watching live broadcasts through IOS system equipment is Ra2, and the number of people watching live broadcasts through a webpage is Ra 3; according to the user access information of the live broadcast room B, the number of people watching live broadcast through the android system equipment in the live broadcast room is Rb1, the number of people watching live broadcast through the IOS system equipment is Rb2, and the number of people watching live broadcast through a webpage is Rb 3.
Further, the proportion of the android system, the IOS system and the webpage in the live broadcast room A is determined to be Ra1 through calculation: ra 2: ra3 ≈ 5:1: 1; determining the proportion of an android system, an IOS system and a webpage in a live broadcast room B as Rb1 through calculation: rb 2: rb3 ≈ 5:2: 1; and the reference proportion is 5:2:1, the fact that the brushing amount behavior exists in the live broadcast room A is determined through comparison, and the fact that the brushing amount behavior does not exist in the live broadcast room B is determined, the live broadcast room A is determined to be the brushing amount live broadcast room, so that the dynamic adjustment of transcoding resources can be conveniently carried out subsequently.
In conclusion, the traffic refreshing behavior of each initial service room is determined based on the access device information, so that the traffic refreshing room can be accurately screened from the initial service rooms, dynamic adjustment of transcoding resources can be performed conveniently in the subsequent process, and the resource utilization rate is improved.
Furthermore, in the process of acquiring the access information and the bandwidth information, considering that the abnormal degree of the measurement brushing room needs to be located through the access information and the bandwidth information, the abnormal degree of the measurement brushing room is reflected in the popularity, and the popularity is directly influenced by the number of people, so that the abnormal degree of the measurement brushing room can be fed back by determining the number of heartbeat people and the number of bandwidth people, and in the embodiment, the specific implementation manner is as follows:
collecting the number of heartbeat people corresponding to the brushing room at a statistical moment through a heartbeat statistical module to serve as the access information; determining the global bandwidth and the average code rate corresponding to the brushing volume room at the statistical moment through a content distribution network; and calculating the bandwidth number corresponding to the brushing amount room according to the global bandwidth and the average code rate to serve as the bandwidth information.
Specifically, the heartbeat counting module is a module for counting the number of visitors to the live broadcast room at regular time, and the number of visitors to the live broadcast room can be fed back by reporting heartbeats to the heartbeat access module; correspondingly, the number of the heartbeat persons is the number of visitors corresponding to the room for counting the number of the times of counting; correspondingly, the statistical time specifically refers to a heartbeat reporting time, which can be set according to actual requirements, and this embodiment is not limited herein. Correspondingly, the global bandwidth specifically refers to the total bandwidth generated by the content distribution network at the statistical moment; correspondingly, the average code rate specifically refers to the code rate after all users average when the video stream is transcoded by the content distribution network at the statistical moment; correspondingly, the bandwidth number of people specifically refers to the number of people for carrying out stream pulling at the statistical moment.
It should be noted that the heartbeat number is the heartbeat reported by the user who is watching the live broadcast room, and is closer to the real number; the bandwidth number is the number fed back by pulling flow, and the bandwidth number is farther away from the real number on the basis of the brushing amount behavior.
Based on this, in order to accurately determine the abnormal degree of the measurement brushing room, the number of heartbeat people corresponding to the measurement brushing room can be collected at a statistical moment through the heartbeat statistical module and used as access information; meanwhile, the global bandwidth and the average code rate corresponding to the brushing room are determined at the statistical moment through the content distribution network, and then the number of people who pull streams from the content distribution network at the statistical moment is determined in a mode of calculating the ratio of the global bandwidth to the average code rate, namely the number of bandwidth people, and the bandwidth people are used as bandwidth information, so that the subsequent abnormal score calculation is facilitated.
That is, the user actually makes a viewing request to the player, the player requests the scheduling system for the actual playing address, and different definitions correspond to different playing addresses. Therefore, after the player takes the playing address, a long link is established with the content distribution network, the content distribution network feeds back the live broadcast picture in real time to pull and watch the live broadcast picture from the content distribution network, and the content distribution network generates bandwidth at the moment. If the bandwidth of the stream of the viewed room is 5M, the bandwidth generated in the content distribution network is also 5M, if there are 100 users, the generated bandwidth is 500M, and when there is a brushing behavior, there is no actual viewing behavior, and the bandwidth generated at the content distribution network end is much less than 500M.
Therefore, the global bandwidth generated by the brushing room and the average code rate of the room stream need to be acquired from the content distribution network in real time for calculation, and then the total number of people who pull the stream at the current time, that is, the number of bandwidth people, can be obtained according to the average code rate of the global bandwidth, so as to facilitate subsequent use. It should be noted that, since the stream code rate of the room fluctuates within a certain range, the average code rate will have a certain error with respect to the true code rate.
According to the above example, after the brushing volume live broadcast room is determined, according to the heartbeat reported by the brushing volume live broadcast room timing heartbeat statistical service, the number of the heartbeat people corresponding to the brushing volume live broadcast room at the time T is determined as S1; meanwhile, according to the real bandwidth M generated by the content distribution network at the time T and the average code rate N, the number of people with the bandwidth is calculated to be M to N, namely S2, so that the abnormal degree can be determined on the basis of the following steps.
In conclusion, by adopting the heartbeat counting module to determine the number of heartbeat people and the content distribution network to determine the number of bandwidth people, the number of people related to the measurement brushing room at the current moment can be respectively determined from two dimensions of flow pulling and access, so that the abnormal degree of the measurement brushing room can be conveniently calculated based on the above, and the transcoding resources can be dynamically adjusted according to the abnormal degree.
And step S204, calculating the abnormal score of the brushing room according to the access information and the bandwidth information.
Specifically, after the access information and the bandwidth information are determined, further, in order to accurately locate the abnormal level of the measurement room, the abnormal score of the measurement room may be calculated by combining the access information and the bandwidth information, so that the abnormal degree of the measurement room is represented by the abnormal score, and then the dynamic allocation of the transcoding resources may be completed by the abnormal score subsequently. The abnormal score specifically refers to a score representing the abnormal degree of the brushing volume room, and the higher the abnormal score is, the higher the abnormal degree of the brushing volume room is, and the stronger the brushing volume behavior contained in the brushing volume room is.
Further, as can be seen from the description contents of the above embodiment, the access information and the bandwidth information correspond to the number of heartbeat people and the number of bandwidth people, respectively, and therefore, the abnormal score corresponding to the brushing amount room can be obtained by calculating the ratio of the two, in this embodiment, the specific implementation manner is as follows:
calculating the difference between the number of the heartbeat people and the number of the bandwidth people to obtain the number of abnormal people corresponding to the measurement brushing room; and calculating the ratio of the abnormal number of people to the number of heartbeat people, and obtaining the ratio of the abnormal number of people corresponding to the brushing room as the abnormal score.
Specifically, the abnormal number is a difference value between the number of heartbeat people and the number of bandwidth people, and is used for representing a difference between the number of heartbeat people and the number of bandwidth people, so that the number of users with a volume brushing behavior in a volume brushing room is reflected; correspondingly, the abnormal people number ratio specifically refers to a ratio between the abnormal people number and the heartbeat people number, is used for representing the proportion of the user number of the brushing amount behavior in the brushing amount room, and is used for representing the abnormal degree of the brushing amount room, namely the abnormal score.
Based on the above, after the number of the heartbeat people and the number of the bandwidth people are obtained, the number of the heartbeat people close to the number of the real people is considered, so that the number of abnormal people corresponding to the brushing room can be determined through the difference value between the number of the heartbeat people and the number of the bandwidth people, namely, the number of the users with abnormal behaviors in the brushing room can be represented; and then calculating the ratio of the abnormal number of people to the number of heartbeat people, namely obtaining the ratio of the user of the brushing amount behavior in the brushing amount room as an abnormal score.
That is to say, the higher the occupancy is, the more the number of the refresh users contained in the refresh room is, the less the corresponding popularity is, and the more the consumed resources are, so that in order to facilitate the subsequent dynamic adjustment of the transcoding resources, the abnormal degree of the refresh room can be represented by the abnormal score, and thus the transcoding processing of the video stream can be completed according to the number of the real users by selecting the corresponding transcoding strategy according to the abnormal score.
Along the above example, the number of heartbeats in the brushing volume live broadcast room is S1, and the number of bandwidth people is S2; on the basis, the difference between the number of heartbeat people S1 and the number of bandwidth people S2 can be calculated firstly to obtain the number of abnormal people S3 corresponding to the brushing volume live broadcast room, then the ratio of the number of abnormal people S3 to the number of heartbeat people S1 is calculated, the ratio of the number of abnormal people is obtained as X according to the calculation result, and therefore the dynamic adjustment of the transcoding mode of the brushing volume live broadcast room can be conveniently carried out according to the ratio of the number of abnormal people X.
In conclusion, the abnormal degree of the brushing volume room is determined by calculating the abnormal number ratio, and the proportion of the users in the brushing volume behavior in the brushing volume room can be reflected through the number of people, so that the subsequent transcoding resource adjustment can be accurately completed on the basis of the proportion, and the purpose of saving resources is achieved.
And S206, transcoding the source video stream of the brushing volume room according to the transcoding strategy corresponding to the abnormal score.
And S208, generating at least one playing address corresponding to the brushing volume room according to the transcoding result.
Specifically, after the abnormal score corresponding to the credit room is determined, a transcoding strategy corresponding to the abnormal score can be further selected to transcode the source video stream corresponding to the credit room, so that the playing addresses corresponding to different definitions can be obtained according to the transcoding result. That is to say, different abnormal scores correspond to different transcoding strategies, and when transcoding is performed on the source video stream corresponding to the brushing volume room, transcoding is performed according to different transcoding strategies, so that at least one playing address corresponding to different abnormal scores can be obtained according to a transcoding result.
That is to say, when transcoding is performed on the source video stream of the cursory room according to different transcoding strategies corresponding to different abnormal score values, one playing address corresponding to the cursory room, or two playing addresses corresponding to the cursory room, or three or more playing addresses corresponding to the cursory room may be obtained according to different transcoding strategies, that is, different transcoding strategies perform n-way transcoding processing on the source video stream by using different transcoding resources, where n is a positive integer greater than or equal to 1. When the source video stream is transcoded by the transcoding strategy to obtain two or more playing addresses, the source video stream is processed according to the code rate in the transcoding strategy to generate video streams with different definitions, so that in the two or more playing addresses corresponding to the refreshing room generated by the transcoding strategy, each playing address corresponds to the video stream with different definitions, and the purpose that when stream pushing is carried out on a client, the video stream with proper definition can be selected according to the playing requirement of the client is achieved.
The transcoding strategy specifically refers to a strategy for transcoding source video streams by different paths, and the abnormal score is inversely proportional to the number of transcoding paths, that is, the higher the abnormal score is, the fewer the transcoding paths corresponding to the transcoding strategy is, otherwise, the lower the abnormal score is, the more the transcoding paths corresponding to the transcoding strategy are, thereby achieving the purpose of saving resources. Correspondingly, the source video stream is specifically an original video stream corresponding to the anchor of the brushing volume room, and is not transcoded. Correspondingly, the playing address specifically refers to a playing address corresponding to a video stream with different definitions, and is used for feeding back the playing address with different definitions to the user according to the playing requirement of the user, so as to play the live broadcast picture corresponding to the definition required by the user in the player.
Further, when transcoding the source video stream according to the transcoding policy corresponding to the abnormal score, a transcoding scheme adapted to the current abnormal score is selected from a plurality of transcoding schemes, so as to achieve the purpose of saving resources, in this embodiment, the specific implementation manner is as follows:
comparing the abnormal score with a plurality of preset score intervals, and determining a target score interval in the score intervals according to a comparison result; determining a target abnormal grade corresponding to the target score interval based on a corresponding relation between pre-established score intervals and abnormal grades, and selecting the transcoding strategy according to the target abnormal grade; and transcoding the source video stream of the flash room by using the transcoding strategy.
Specifically, the score interval is an interval divided by two set score thresholds, is used for measuring the segment position to which the abnormal score belongs, and is used for determining a transcoding strategy of a corresponding brushing amount room; correspondingly, the target score interval specifically refers to a score interval to which the abnormal score belongs after being compared with the abnormal score in the multiple score intervals, and is used for determining the abnormal level of the measurement brushing room, so that the transcoding strategy corresponding to the level is selected. Correspondingly, the abnormal grade specifically refers to a grade representing the abnormal degree of the measurement refreshing room, and different abnormal grades correspond to different transcoding strategies, so that the transcoding strategy corresponding to the measurement refreshing room can be selected by determining the abnormal grade so as to be used for transcoding the source video stream of the measurement refreshing room.
The abnormal score is in a direct proportion relation with the abnormal grade, namely the higher the abnormal score is, the higher the abnormal grade of the brushing amount room is. The abnormal grade and the number of transcoding paths corresponding to the transcoding strategy are in an inverse relation, namely the higher the abnormal grade is, the fewer the number of transcoding paths corresponding to the transcoding strategy selected for the traffic brushing room is; correspondingly, the abnormal score and the number of transcoding paths corresponding to the transcoding strategy are in an inverse relation, namely the higher the abnormal score is, the fewer the number of transcoding paths corresponding to the transcoding strategy selected for the traffic brushing room is.
Correspondingly, the relationship between the score interval and the abnormal grade is a pre-established relationship, and different score intervals correspond to different abnormal grades, for example, if the score interval is S1-S2, the abnormal grade is A1 grade; the score interval is S2-S3, the exception grade is A2 grade, and so on; in practical application, the corresponding relationship between the score interval and the abnormal level may be established by selecting different granularities according to a practical application scenario, and this embodiment is not limited herein.
In practical applications, the setting of the multiple score intervals may be adjusted according to practical application scenarios, and the embodiment is not limited herein. The smaller the granularity of the score interval is, the more people really watching the live broadcast are, and on the basis, a corresponding multi-channel transcoding strategy can be selected to meet the watching requirements of different users by continuously improving the number of the transcoding definition.
Based on this, after the abnormal score is obtained, the abnormal score can be compared with a plurality of score intervals, a target score interval to which the abnormal score belongs can be determined according to a comparison result, then a target abnormal grade corresponding to the brush volume room can be determined through the target score interval by inquiring a corresponding relation between the pre-established score interval and the abnormal grade, so that a transcoding strategy of the brush volume room is positioned according to the target abnormal grade, and finally, a source video stream of the brush volume room is transcoded by using the transcoding strategy corresponding to the abnormal score.
In conclusion, the abnormal level of the refreshed volume room is reasonably positioned by setting a plurality of score intervals, so that transcoding processing on the source video stream by selecting a strategy closer to the refreshed volume room from a plurality of transcoding strategies can be realized, the resource utilization rate can be fully improved, and the purpose of saving resources is achieved.
Furthermore, considering that different score intervals correspond to different abnormal grades, and different abnormal grades correspond to different transcoding strategies, when performing comparison, a transcoding strategy corresponding to an abnormal grade needs to be selected according to a comparison result to perform transcoding processing, so as to generate playing addresses corresponding to different definitions, in this embodiment, a specific implementation manner is as follows:
(1) under the condition that the abnormal score is determined to be larger than or equal to the score threshold of the maximum score interval according to the comparison result, taking the maximum score interval as the target score interval; correspondingly, generating at least one play address corresponding to the brushing volume room according to the transcoding result comprises: and generating a source playing address corresponding to the source video stream according to the transcoding result, wherein the source playing address is used as at least one playing address corresponding to the brushing volume room.
Specifically, the maximum score interval specifically refers to an interval in which the number of the brushing behavior users representing the brushing room is the highest, at this time, resource waste will be maximized, and in order to achieve the purpose of saving resources, a policy which saves the most resources is selected as a transcoding policy, that is, the transcoding policy will not transcode the source video stream; the score threshold of the maximum score interval refers to the lower limit score of the interval. Correspondingly, the source playing address is the playing address directly corresponding to the source video stream, and transcoding processing is not performed.
Based on this, when the abnormal score is determined to be greater than or equal to the score threshold of the maximum score interval according to the comparison result, it is indicated that the number of abnormal users in the brushing volume room exceeds the maximum upper limit, in order to save resources, a default transcoding strategy can be selected to process the source video stream at this time, that is, the source video stream is not transcoded, and a source playing address corresponding to the source video stream is directly generated as at least one playing address corresponding to the brushing volume room, so as to achieve the purpose of saving resources.
According to the above example, the ratio of the number of abnormal people is X, at the moment, the X is compared with the threshold value of each interval, the fact that the X is larger than the lower limit threshold value A of the maximum interval is determined according to the comparison result, it is shown that the number of abnormal people contained in the current volume brushing live broadcast room exceeds A, the number of people actually watched is not right, in order to save resources, transcoding can be carried out on the source video stream of the volume brushing live broadcast room, the playing address corresponding to the source video stream is directly generated and provided for audiences, at the moment, the audiences can only watch live broadcast through the definition corresponding to the source video stream, and switching of live broadcast definition cannot be carried out.
(2) Determining that the abnormal score is smaller than a score threshold of a maximum score interval according to a comparison result, and taking a middle score interval as the target score interval under the condition that the abnormal score is larger than or equal to the score threshold of the middle score interval; correspondingly, generating at least one play address corresponding to the brushing volume room according to the transcoding result comprises: and generating a source playing address and a reference definition playing address corresponding to the source video stream according to the transcoding result, wherein the source playing address and the reference definition playing address are used as at least one playing address corresponding to the brushing volume room.
Specifically, the intermediate score interval specifically refers to an interval representing a moderate proportion of the number of the brushing behavior users in the brushing room, and at this time, a certain amount of resources are wasted; correspondingly, the reference definition playing address is a playing address obtained by transcoding the source video stream according to a reference transcoding mode.
Based on this, when the abnormal score is determined to be smaller than the lower limit score threshold of the maximum score interval according to the comparison result, and is greater than or equal to the lower limit score threshold of the middle score interval, it is described that the number of abnormal users in the brushing volume room is smaller than the maximum upper limit, but is still higher than the middle upper limit.
According to the above example, the ratio of the number of abnormal people is X, at the moment, the X is compared with the threshold value of each interval, the X is determined to be smaller than A and larger than B according to the comparison result, the fact that the number of the abnormal people contained in the current volume brushing live broadcast room exceeds B but is not larger than A is shown, the number of the real watching people is nearly half, in order to provide the playing address meeting the watching requirement of the user for the part of users, one path of transcoding can be carried out on the source video stream, the definition of the transcoding is very low, namely, the definition of the standard definition, the playing address corresponding to the definition is obtained according to the transcoding result, and the playing address corresponding to the source video stream is obtained, so that when the user watches the source video stream, the playing address of the standard definition can be selected, or the playing address of the source definition is watched by live broadcast.
(3) Under the condition that the abnormal score is smaller than a score threshold of a reference score interval according to the comparison result, taking the reference score interval as the target score interval; correspondingly, generating at least one play address corresponding to the brushing volume room according to the transcoding result comprises: and generating a source playing address corresponding to the source video stream according to the transcoding result, and at least two definition playing addresses corresponding to different definitions, wherein the source playing address and the at least two definition playing addresses serve as at least one playing address corresponding to the brushing volume room.
Specifically, the reference score interval specifically refers to an interval in which the number of the users representing the brushing behavior of the brushing room is relatively low, at this time, a certain waste of resources also exists, in order to achieve the purpose of saving resources, a policy including at least two transcoding numbers is selected as a transcoding policy, that is, the transcoding policy only transcodes the source video stream at least twice, correspondingly, the definition playing address specifically refers to a playing address corresponding to different definitions, and different definition playing addresses are playing addresses obtained after different transcoding processing is performed on the source video stream.
Based on this, when it is determined that the abnormal score is smaller than the upper limit score threshold of the reference score interval according to the comparison result, it is indicated that the number of abnormal users in the brushing volume room is small, but the abnormal users still exist, in order to save resources, a transcoding strategy including at least two transcoding numbers may be selected to process the source video stream, so as to generate a source playing address and at least two definition playing addresses corresponding to the source video stream according to the transcoding result, and it is sufficient to use the playing address as at least one playing address corresponding to the brushing volume room, so as to achieve the purpose of saving resources.
According to the above example, the ratio of the number of abnormal people is X, at the moment, the X is compared with the threshold value of each interval, the fact that the X is smaller than the C is determined according to the comparison result, it is stated that the number of abnormal people contained in the current brushing volume live broadcasting room is not large, in order to provide a playing address meeting the watching requirement of a real user, the source video stream can be subjected to multi-channel transcoding, the definition of each channel of transcoding is different, namely, the standard definition, the high definition and the ultra-high definition are contained, the playing address corresponding to the standard definition is obtained according to the transcoding result, the playing address of the high definition, the playing address corresponding to the ultra-high definition and the playing address corresponding to the source video stream are obtained, and therefore when the user watches the live broadcasting with the appropriate playing address selected according to the requirement.
In practical application, when a plurality of score intervals are set, the division granularity of the score intervals can be selected according to practical application scenes, and a set number of score intervals can be created by adopting division strategies with different granularities for different live broadcast scenes, so that in a transcoding stage, different levels of transcoding control can be performed for different traffic volume refreshing rooms with different traffic volume refreshing behaviors, and the embodiment is not limited herein.
On this basis, in the stream pushing stage, stream pushing is completed by analyzing the viewing request of the user, and in this embodiment, the specific implementation manner is as follows:
