Detailed Description
Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
Before introducing the method, the apparatus, the storage medium, and the electronic device for determining a live broadcast duration provided by the present disclosure, first, an application scenario related to each embodiment in the present disclosure is introduced, where the application scenario may be a live broadcast system, and deployment of the live broadcast system may be as shown in fig. 1, and may include: the system comprises a business server, a streaming media server and a plurality of clients. Each client is provided with live broadcast software, a user can use the live broadcast software to communicate with a service end and a streaming media service end through a network, the service end provides service (such as charging service, payment service, password service, login service and the like) for the live broadcast software, the streaming media service end provides streaming media service (such as voice transmission, video transmission and the like) for the live broadcast software, and the service end and the streaming media service end can be understood as a live broadcast platform. The client may be a mobile terminal such as a smart phone, a tablet computer, a smart television, a smart watch, a PDA (Personal Digital Assistant, chinese), a portable computer, or a fixed terminal such as a Digital TV or a desktop computer. The service server and the streaming media server can be deployed on a local server or a cloud server. It should be noted that the service server and the streaming media server are only used to limit different services provided for live broadcast software, and the service server and the streaming media server may be deployed on the same server or on different servers, for example, live broadcast software may use a streaming media server provided by a third party.
Fig. 2 is a flowchart illustrating a method for determining a live broadcast duration according to an exemplary embodiment, where as shown in fig. 2, the method, applied to a service end, may include the following steps:
For example, a user may enter a live room through live software installed on a client. One or more clients may be included in the live room. The business server maintains an access record table for the live broadcast room, when each client enters the live broadcast room, an access record corresponding to the client is newly added in the access record table, the access record comprises a start time and an end time, wherein the start time is the time when the client enters the live broadcast room (which can be understood as the time when the client establishes a link with the streaming media server), the end time is empty when the client enters the live broadcast room, and when the client exits the live broadcast room, the time is recorded as the time when the client exits the live broadcast room. Therefore, the service server can count the time length of each client using the live broadcast room according to the access record table, namely the live broadcast time length of each client. However, due to the situations of network instability, client abnormality (for example, system crash of the client, the client cleaning up the process of the live broadcast software in the background, etc.), etc., it may cause the client to abnormally disconnect from the streaming server or the service server, that is, the client abnormally exits from the live broadcast room, that is, the service server considers that the client is in the live broadcast room at this time, but actually the link between the client and the streaming server is disconnected. For the client which logs out abnormally, the service server cannot know when the client logs out of the live broadcast room, so that the live broadcast time length of the client in the live broadcast room (namely the time length of the client using the live broadcast service) cannot be accurately counted, and charging cannot be carried out according to the live broadcast time length of the client.
If the client is in the live broadcast room, a link is established between the client and the streaming media server, and data transmission is performed between the client and the streaming media server through the link (for example, the client uploads audio and video data to the streaming media server, or the streaming media server sends audio and video data uploaded by other clients in the live broadcast room to the client, etc.). If the client abnormally exits the live broadcast room, the link between the client and the streaming media server is abnormal, so that whether the client abnormally exits can be detected through whether the link between the client and the streaming media server is abnormal. The link between the client and the streaming media server is abnormal, and may be the case that no data transmission is available within a preset time (for example, 1 min), or the link is disconnected. When detecting that the link between the streaming media server and the target client is abnormal, the streaming media server sends a flow interruption callback request to the service server, wherein the number of the target clients can be one or more. The blackout callback request may include an identification of the target client (e.g., userId) and may also include an identification of the live room. It will be appreciated that the blackout callback request can indicate that the target client has exited the live room abnormally. After receiving the cut-off callback request, the service server can know that the target client abnormally exits the live broadcast room.
It should be noted that, in the live broadcasting system, multiple live broadcasting rooms may exist at the same time, one live broadcasting room may be understood as a live broadcasting conference, each live broadcasting room corresponds to a room ID (which may also be understood as a conference ID of the live broadcasting conference) capable of uniquely identifying the live broadcasting room, and the live broadcasting room in the embodiment of the present disclosure may be any live broadcasting room in the live broadcasting system.
And 102, determining the flow break time according to the flow break callback request.
For example, the service server may determine the cut-off time according to the cut-off callback request, where the cut-off time may be understood as the time when the target client exits from the live broadcast room, which is determined by the service server according to the cut-off callback request. Specifically, the interruption callback request may directly carry a time when the streaming media server detects that the link with the target client is abnormal, and then the service server may directly use the time as the interruption time. The flow interruption callback request may also carry a timestamp for sending the flow interruption callback request, and the service server may determine the flow interruption time according to the timestamp. The service server can also use the time of receiving the flow interruption callback request as the flow interruption time.
And 103, searching a target access record corresponding to the target client in an access record table corresponding to the live broadcast room, wherein the access record table comprises a plurality of access records, each client generates a corresponding access record when entering the live broadcast room, and the start time of the access record corresponding to the client is the time when the client enters the live broadcast room.
And step 104, if the end time included in the target access record is empty, modifying the end time included in the target access record into the flow break time, and determining the live broadcast time length of the target client according to the modified target access record.
For example, after determining that the target client abnormally exits the live broadcast room, the service server may search for a target entry and exit record corresponding to the target client in the maintained entry and exit record table. Wherein, each entry and exit record recorded in the entry and exit record table at least comprises three fields: the client comprises an identification of the client, a starting time and an ending time, wherein the identification of the client is used for indicating the client corresponding to the access record, the starting time is used for recording the time when the corresponding client enters the live broadcast room, and the ending time is used for recording the time when the corresponding client exits the live broadcast room. In general, since the service server cannot know when the target client exits the live broadcast room, the end time may be empty in the entry and exit record corresponding to the target client.
Therefore, the target access record can be searched in the access record table according to the identification of the target client. And then judging whether the end time included by the target entry and exit record is empty, if the end time included by the target entry and exit record is not empty, comparing the end time included by the target entry and exit record with the flow break time, and determining the end time included by the target entry and exit record as the previous time in the end time and the flow break time. For example, the target entry and exit record includes an end time of 10:50, flow break time of 10:52, the target entry and exit record may be maintained, and for example, the target entry and exit record may include an end time of 12:17, the flow-off time is 12:11, the end time included in the target entry and exit record may be modified to 12:11. if the end time included in the target entry and exit record is empty, the end time included in the target entry and exit record may be modified to the flow break time, that is, the flow break time is filled in the target entry and exit record as the end time. Therefore, the business server can determine the live broadcast time of the target client according to the modified target access record. For example, the modified target entry and exit record includes a start time of 8:00, end time 8: and 32, the live broadcast time of the target client is 32 minutes. Furthermore, the service server can also charge according to the live broadcast time of the target client.
When the streaming media server detects that the link between the streaming media server and the target client is abnormal, the streaming media server sends a cut-off callback request to the service server, so that the service server can determine the time when the target client abnormally exits the live broadcast room according to the cut-off callback request, thereby modifying the target access record corresponding to the target client, and enabling the service server to accurately determine the live broadcast time of the client abnormally exiting the live broadcast room according to the modified target access record.
In summary, the service server of the present disclosure first receives a cut-off callback request sent by the streaming media server when detecting that a link with a target client is abnormal, where the target client is any client in a live broadcast. And then, according to the cut-off callback request, determining cut-off time, and searching a target access record corresponding to the target client in an access record table corresponding to the live broadcast room, wherein the access record table comprises access records generated when each client enters the live broadcast room. And if the end time included by the target access record is empty, modifying the end time included by the target access record into the flow break time, and determining the live broadcast time of the target client according to the modified target access record. According to the method and the device, when the streaming media server detects that the link between the streaming media server and the target client is abnormal, the streaming media server sends the cut-off callback request to the service server, and the service server can determine the time when the target client abnormally exits the live broadcast room according to the cut-off callback request, so that the target access record corresponding to the target client is modified, and the live broadcast time of the client which abnormally exits the live broadcast room can be accurately determined.
Fig. 3 is a flowchart illustrating another method for determining a live time duration according to an exemplary embodiment, and as shown in fig. 3, an implementation manner of step 102 may include:
and 1021, if the cutoff callback request comprises abnormal time, taking the abnormal time as cutoff time, wherein the abnormal time is the time when the streaming media server detects that the link between the streaming media server and the target client is abnormal.
For example, the interruption callback request sent by the streaming media server may include a time when the streaming media server detects that the link with the target client is abnormal, that is, an abnormal time. Then, the service server may directly use the abnormal time as the cut-off time, that is, the time when the streaming media server detects that the link with the target client is abnormal is determined as the time when the target client exits the live broadcast room abnormally. The interruption callback request may not include the abnormal time, and the service server may use the time when the interruption callback request is received as the interruption time, that is, the time when the interruption callback request is received, as the time when the target client abnormally exits the live broadcast room.
Fig. 4 is a flowchart illustrating another method for determining a live time duration according to an exemplary embodiment, and as shown in fig. 4, the implementation manner of step 103 may be:
and if a plurality of target entry and exit records corresponding to the target client exist in the entry and exit record table, taking the target entry and exit record with the latest starting time as the latest target entry and exit record.
Accordingly, the implementation of step 104 may include:
in step 1041, if the end time included in the latest target entry and exit record is empty, the end time included in the latest target entry and exit record is modified into the flow break time.
And 1042, determining the live broadcast time length of the target client according to the other target access records and the modified latest target access record, wherein the other target access records are target access records except the latest target access record in the plurality of target access records.
For example, for the same live broadcast room, there may be a scene in which the target client enters the live broadcast room for multiple times, and accordingly, there may be multiple target entry and exit records corresponding to the target client in the entry and exit record table. In step 101, a request for call back is received, which indicates that the target client may exit the live broadcast room abnormally for the last time, and then the target entry and exit record with the latest start time may be used as the latest target entry and exit record. Correspondingly, whether the end time included in the latest target entry and exit record is empty is judged. If the end time included in the latest target entry and exit record is not empty, the end time included in the latest target entry and exit record may be compared with the flow break time, and the end time included in the latest target entry and exit record may be determined as the previous time of the end time and the flow break time. If the end time included in the latest entry and exit record is empty, the end time included in the latest target entry and exit record may be modified to the current break time. Finally, the live time duration of the target client may be determined according to all target access records (including the modified latest target access record). For example, target entry and exit are recorded as 2, and the shut-off time is 9:51, the first target entry and exit record includes a start time of 8:00, end time 8:32, the second target entry-exit record includes a start time of 9:07, end time is empty. Then the second target entry and exit record is the latest entry and exit record, and the end time included in the second target entry and exit record may be modified to 9:51. then the live duration of the target client, namely (8.
Fig. 5 is a flowchart illustrating another method for determining a live time duration according to an exemplary embodiment, where as shown in fig. 5, the method further includes:
And 106, generating a second access record corresponding to the first client in the access record table, wherein the start time of the second access record is the first time.
For example, when the service server detects that the first client enters the live broadcast room at the first time, it may first search in the entry and exit record table whether a first entry and exit record corresponding to the first client exists. If the first in-out record does not exist, the first client is indicated to enter the live broadcast room for the first time. If there is a first entry and exit record (which may be one or more), it is indicated that the first client is not entering the live room for the first time. Meanwhile, a second entry and exit record corresponding to the first client can be generated in the entry and exit record table, and the second entry and exit record can be understood as an entry and exit record corresponding to the first client entering the live broadcast room at this time, wherein the included start time is the first time, and the end time is now empty.
If the first client does not enter the live broadcast room for the first time and exits abnormally when exiting the live broadcast room for the last time, the end time included in the entry and exit record corresponding to the first client entering the live broadcast room for the last time may be empty, which may cause the service server to be unable to accurately determine the live broadcast time of the first client. For example, after the first client abnormally exits from the live broadcast room, the first client enters the live broadcast room again within a short time (for example, 10 s), at this time, the service server may not receive the flow interruption callback request sent by the streaming media server and indicating that the first client abnormally exits from the live broadcast room, and then the end time included in the entry and exit record corresponding to the first client entering the live broadcast room last time is still null. In order to avoid the above situation, the service end may modify the end time included in the first entry and exit record to the first time when the first entry and exit record exists and the end time included in the first entry and exit record is empty. Then, if the service server receives the flow callback request sent by the streaming media server and indicating that the first client abnormally exits the live broadcast room last time, the end time included in the second entry and exit record may be modified to be the flow break time according to the implementation manners of steps 101 to 104. When the first client exits the live broadcast room, the end time included in the second entry and exit record (i.e. the implementation manner of step 114 mentioned later) is updated according to the time when the first client exits the live broadcast room, so as to ensure that the end time included in the second entry and exit record can indicate the time when the first client exits the live broadcast room.
Fig. 6 is a flowchart illustrating another method for determining a live time duration according to an exemplary embodiment, where as shown in fig. 6, the method may further include:
and 108, marking the modified target entry and exit record as a first state.
And step 109, marking the modified first entry and exit record as a second state.
And step 110, responding to an end instruction for the live broadcast room, traversing each entry-exit record in the entry-exit record table, if an abnormal entry-exit record with empty end time exists, modifying the end time included in the abnormal entry-exit record to be current time, and marking the abnormal entry-exit record to be in a third state.
And step 111, determining the total live broadcast duration of the live broadcast room according to all the in-out records in the in-out record table.
For example, when the business server modifies an entry and exit record (e.g., the target entry and exit record, the first entry and exit record, and the abnormal entry and exit record), the entry and exit record may be marked to indicate that the entry and exit record is in a modified state. If the business server does not modify the entry and exit record (i.e. the scenario where the client normally exits), the entry and exit record may be in an unmodified state (i.e. the fourth state mentioned later). Specifically, after receiving the blackout callback request, the modified target entry and exit record according to the blackout time may be marked as the first state (may be marked as end _ type = 1). In case it is detected that the client enters the live room at a first time, the first entry and exit record, modified at the first time, may be marked as the second state (which may be marked as end _ type = 2). If an end instruction for the live room is detected, which indicates that the live room is ended (it can be understood that the host ends the live conference), each entry and exit record in the entry and exit record table may be traversed, and if there is an abnormal entry and exit record including an end time that is empty, the end time included in the abnormal entry and exit record may be modified to the current time, and the abnormal entry and exit record may be marked as a third state (which may be written as end _ type = 3). It should be noted that the operation of traversing the entry and exit log table may be performed after a period of time when the end instruction is detected, so as to avoid the possibility of an unreceived blackout callback request. For example, the operation of entering and exiting the log table may be traversed 8 minutes after the end instruction is detected, and then the current time is 8 minutes after the end instruction is detected.
And finally, after the live broadcasting room is finished, determining the total live broadcasting time length of the live broadcasting room according to all the access records in the access record table. For example, the difference between the end time and the start time included in each entry and exit record may be obtained to obtain the duration corresponding to each entry and exit record, and then the durations corresponding to all the entry and exit records are summed to obtain the total live broadcast duration. For another example, the total live time length may be calculated according to formula one:
wherein A represents the total live broadcast time length, S represents the total time length from the beginning to the end of the live broadcast room, N1 represents the number of first type clients which completely participate in the live broadcast room, N2 represents the number of second type clients which normally enter and exit the live broadcast room, N3 represents the number of third type clients which normally enter the live broadcast room but abnormally exit the live broadcast room, T' i Indicating the end time, T, of the ith second type client i Represents the starting time, P' j Represents the end time, P, of the jth third class client j Indicating the start time of the jth client of the third class. It should be noted that the second type clients and the third type clients can enter the live broadcast room multiple times, so that the formula (T' i -T i ) The method can indicate that the ith second type client enters the live broadcast room for multiple times, and the sum of the corresponding live broadcast time lengths (P ') of the ith second type client entering the live broadcast room each time' j -P j ) The method can be expressed as that the jth third-class client enters the live broadcast room for multiple times, and the sum of the corresponding live broadcast time lengths of the j third-class clients entering the live broadcast room every time.
Fig. 7 is a flowchart illustrating another method for determining a live time duration according to an exemplary embodiment, where as shown in fig. 7, the method may further include:
and step 112, in response to detecting that the second client exits from the live broadcast room at the second time, searching whether a third entry-exit record corresponding to the second client exists in the entry-exit record table, where the second client is any client in the live broadcast room.
And step 113, if a third in-out record exists in the in-out record table, the end time included by the third in-out record is empty, and the third in-out record is in a fourth state, modifying the end time included by the third in-out record into a second time, wherein the fourth state is different from the first state, the second state and the third state.
And step 114, if a third in-out record exists in the in-out record table and the third in-out record is in the first state, the second state or the third state, modifying the end time included in the third in-out record into a second time.
And step 115, determining the live broadcast time length of the second client according to the modified third in-out record.
For example, the service server detects that the second client exits from the live broadcast room at the second time, that is, the second client normally exits from the live broadcast room. Then it may be looked up in the entry and exit record table whether there is a third entry and exit record corresponding to the second client. In the case where there is a third in-out record, the end time included in the third in-out record is empty, and the third in-out record is in the fourth state (i.e., the third in-out record is illustrated as being in an unmodified state), the end time included in the third in-out record may be modified to be the second time. That is, when the second client normally exits the live broadcast room, the end time included in the third entry-exit record may be recorded as the time when the second client is detected to exit the live broadcast room. In the case where there is a third in-out record and the third in-out record is in the first state, or the second state, or the third state (i.e., the state indicating that the third in-out record is corrected), the end time included in the third in-out record may be modified to the second time.
Fig. 8 is a flowchart illustrating another method for determining a live time duration according to an exemplary embodiment, where as shown in fig. 8, the method may further include:
and step 116, responding to the end instruction aiming at the live broadcast room, and modifying the empty end time in the access record table into the time when the end instruction is detected.
For example, if an end instruction for the live broadcast room is detected, which indicates that the live broadcast room is ended (it may be understood that the host ends the live broadcast conference), each entry and exit record in the entry and exit record table may be traversed, and the end time that is empty may be modified to the time when the end instruction is detected. It will be appreciated that when the live room ends, the time of the live room end can be uniformly filled in each entry and exit record that includes an end time that is empty. And finally, after the live broadcasting room is finished, determining the total live broadcasting time of the live broadcasting room according to all the access records in the access record table. For example, the difference between the end time and the start time included in each entry and exit record may be obtained to obtain the duration corresponding to each entry and exit record, and then the durations corresponding to all the entry and exit records are summed to obtain the total live broadcast duration, or the total live broadcast duration may be calculated according to the formula one.
