Description
Technical Field
The invention relates to the technical field of computer networks, in particular to a video live broadcast service system and a video live broadcast service method.
Background
In the live video broadcast process, a user end (live broadcast end) corresponding to a host user uploads live video recorded in real time to a service system, and a user end (viewing end) corresponding to a watching user pulls the corresponding live video from the service system to realize live video broadcast. The existing live video service system is a server topology of multiple service levels, and the service system comprises: a total server, a cluster comprising a plurality of intermediate servers, and a cluster comprising a plurality of edge servers. The hierarchy of the overall servers is located above the hierarchy of the intermediate servers, which is located above the hierarchy of the edge servers. The method comprises the steps that an edge server firstly receives a live video uploading request sent by a live video terminal, and the live video is transmitted to a total server through an intermediate server, wherein the live video uploading request is an uplink transmission process of the live video; the master server transmits the uploaded live video to the intermediate server, and the edge server pulls the direct-broadcast video from the intermediate server after receiving the live video playing request sent by the watching end, which is a downlink transmission process of the live video.
In the downlink transmission process in the prior art, as the intermediate server is a cluster service, before the total server issues the live video to the intermediate server, the total server needs to enumerate an intermediate server according to an enumeration algorithm, and issues the live video to the intermediate server. Accordingly, after receiving a live video playing request sent by a viewing end, the edge server also needs to enumerate an intermediate server storing the live video according to a consistent enumeration algorithm, and pull the direct-broadcasting video from the intermediate server. The total server and each edge server need to maintain the consistency of the intermediate server list and the enumeration algorithm to effectively finish the issuing of the live video. If the intermediate server cluster is changed or failed or the enumeration algorithm is updated, the change condition of the intermediate server list or the updated version of the enumeration algorithm needs to be synchronized to the total server and each edge server, however, as the edge server cluster is usually huge, the maintenance work of the data consistency is very complex, once the inconsistency problem occurs, the failure of pulling the direct-broadcasting video by the edge server is very easy to cause, and the service performance of the direct-broadcasting service system is greatly affected.

Detailed Description
Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
Fig. 1 shows a schematic architecture diagram of a live video service system according to an embodiment of the present invention, and as shown in fig. 1, the live video service system includes: the system further comprises a total server, a first server cluster comprising a plurality of intermediate servers, and a second server cluster comprising a plurality of edge servers: and a third server cluster. The video live broadcast service system of the invention is a topology structure of multiple service levels. The hierarchy of the total servers is located above the hierarchy of the intermediate servers, the hierarchy of the intermediate servers is located above the hierarchy of the edge servers, and the third server and the intermediate servers belong to the same hierarchy. The intermediate server, the edge server and the third server are all clustered services, and optionally, the total server is clustered services, and there may be a plurality of total servers.
The total server is used for: receiving the uploaded live video, and requesting an enumeration result of the intermediate server from a third server cluster; according to the enumeration result, the live video is issued to the intermediate server; the edge server is used for: requesting an enumeration result of the intermediate server from a third server cluster according to the live video pulling request; and pulling the direct-broadcast video from the intermediate server according to the enumeration result; any one of the third servers in the third server cluster is configured to: maintaining an intermediate server list and an intermediate server enumeration algorithm, and obtaining an enumeration result of an intermediate server according to the intermediate server enumeration algorithm after receiving a request sent by a total server or an edge server.
Unlike the prior art, the system adds a third server cluster. The third server is a server deployed at the same level as the intermediate server, and does not provide a specific video distribution service, so the number of servers in the third server cluster is far smaller than the number of intermediate servers and edge servers. In the actual implementation process, a certain number of servers can be screened from the original intermediate server cluster, so that video distribution service is not provided, and an intermediate server list and an intermediate server enumeration algorithm are specially maintained; or, a certain number of servers are added in the hierarchy of the intermediate servers, so that the intermediate servers are specially maintained for an intermediate server list and an intermediate server enumeration algorithm. In summary, the third server cluster in the system is responsible for maintaining the intermediate server list and the intermediate server enumeration algorithm, and the total server and the edge server do not need to maintain the intermediate server list and the intermediate server enumeration algorithm.
Further, each third server in the third server cluster obtains a list of intermediate servers and an intermediate server enumeration algorithm from the configuration management center. The third server may periodically request a list of intermediary servers from the configuration management center and an intermediary server enumeration algorithm; or after the intermediate server list is changed or the enumeration algorithm is updated, the configuration management center synchronizes the changed intermediate server list or the updated enumeration algorithm to all the third servers. Since the number of third servers is far smaller than the number of total servers and edge servers, the third servers maintain the consistency of the intermediate server list and the enumeration algorithm, and the workload of synchronous work is greatly reduced.
The downlink transmission process of the system specifically comprises the following steps: after receiving the live video transmitted in the uplink, the total server sends a request to each third server in the third server cluster, and after each third server receives the request, the enumeration results of the intermediate servers are calculated according to the intermediate server list and the enumeration algorithm maintained by the total server, namely, the live video is issued to which intermediate server. And each third server returns the enumeration result to the total server. Under normal conditions, the enumeration results of the third servers should be consistent, and then the total server issues the live video to the enumerated intermediate server.
After receiving the request, the edge server sends a request to each third server in the third server cluster, and after receiving the request, each third server calculates an enumeration result of the intermediate server according to an intermediate server list and an enumeration algorithm maintained by the edge server, namely, which intermediate server to pull the direct broadcast video from. And each third server returns the enumeration result to the edge server. Under normal circumstances, the enumeration results of the respective third servers should be consistent, and the edge server pulls the direct-cast video from the enumerated intermediate server.
It should be noted that, the specific implementation of the enumeration algorithm is not limited in the present invention, and any enumeration algorithm provided in the prior art may be used. The enumeration algorithm can ensure that the intermediate servers enumerated for the same live video are identical, namely, the issuing targets of the same live video total server and the pulling targets of the edge servers are identical.
In an abnormal situation, the third server cluster fails to maintain the consistency of the intermediate server list and the enumeration algorithm, and then the enumeration results of the respective third servers may be inconsistent. If the total server compares that the enumeration results returned by the third servers are inconsistent, an alarm prompt can be sent to enable the third servers to request the intermediate server list and the intermediate server enumeration algorithm from the configuration management center again, so that the intermediate server list and the intermediate server enumeration algorithm of the third servers are consistent. If the edge server compares that the enumeration results returned by the third servers are inconsistent, for example: and if the number of the intermediate servers enumerated by each third server is more than two, the edge server initiates polling to the more than two intermediate servers until the live video is pulled. Specifically, if the polled intermediate server has the live video, the live video is sent to an edge server; if the polled intermediate server does not have the live video, an error code is sent to the edge server.
The video live broadcast service system of the embodiment supports file type video live broadcast. In the uplink transmission process, live video is streamed to a total server; in the downstream transmission process, the live video stream is converted into a file format. Specifically, the system performs slice processing on the data frame of the live video stream based on HLS (HTTP Live Streaming) protocol. The HLS protocol is a dynamic code stream adaptive protocol based on a hypertext transfer protocol, in which a live video stream is sliced into continuous, very short duration media files, and corresponding index files are generated, which are called slice files, and the index files are called slice index files. In the HLS protocol, the slice file format is a TS file and the slice index file format is an m3u8 file. The slice index file includes file information of a corresponding slice file, and the file information includes a slice name, a slice type, a slice length, a slice storage location, a slice serial number, a slice size, a stream time, a stream source, and/or the like of the slice file.
In the system, the slicing processing of the live video stream can be completed by an intermediate server. Specifically, after the total server sends the live video stream down to the intermediate server, the intermediate server performs slicing processing to convert the streaming video into a video file; the edge server pulls the video file from the intermediate server, the edge server has certain buffering capacity, and the pulled video file is buffered and then sent to the watching end.
In the system, the slicing processing of the live video stream can also be completed by the third server. Specifically, the total server sends the live video stream to any third server, and the third server performs slicing processing to convert the streaming video into a video file. Then, the third server can return the video file to the total server, and the video file is issued to the intermediate server by the total server; or after the third server selects the intermediate server through enumeration, the video file is directly distributed to the intermediate server. The edge server pulls the video file from the intermediate server, the edge server has certain buffering capacity, and the pulled video file is buffered and then sent to the watching end.
According to the video live broadcast service system provided by the invention, the third server cluster is additionally arranged, the third server cluster is used for specially maintaining the intermediate server list and the intermediate server enumeration algorithm, and the total server and the edge server do not need to maintain the intermediate server list and the intermediate server enumeration algorithm. Compared with the prior art, on one hand, the system decouples the relevance of data maintenance consistency between different server cluster levels (a total server cluster and an edge server cluster), and avoids the complexity of data consistency maintenance between two different server levels; on the other hand, the third server cluster is not a server for providing core video distribution service, the number of servers of the cluster is far smaller than that of service core servers such as a total server, an intermediate server and an edge server, and when the change condition of an intermediate server list or the upgrading condition of an enumeration algorithm occurs, the efficiency of realizing synchronous update of the third server cluster is very high; in still another aspect, the master server and the edge server can focus on the distribution of video files without starting an enumeration process, so that the video distribution efficiency in the live broadcast process is improved. In summary, the service performance of the video live broadcast service system is greatly improved.
Fig. 2 shows a flowchart of a live video service method according to an embodiment of the invention. The method is implemented based on the video live broadcast service system, as shown in fig. 2, and comprises the following steps:
step S201, receiving the uploaded live video, requesting an enumeration result of an intermediate server from a third server cluster, and issuing the live video to the intermediate server according to the enumeration result;
step S202, requesting an enumeration result of an intermediate server from a third server cluster according to a live video pulling request, and pulling a direct-broadcasting video from the intermediate server according to the enumeration result;
step S203, distributing the live video to the viewing end.
The method is different from the prior art in the downlink transmission process of live video broadcast. The uplink transmission process of the live video broadcast is consistent with the prior art, and is not repeated.
In the step S201, the total server receives the live video uploaded in the uplink transmission process, and requests the enumeration result of the intermediate server from the third server cluster because the total server does not maintain the intermediate server list and the enumeration algorithm of the intermediate server. Further, the total server sends a request to each third server in the third server cluster to acquire an enumeration result of the intermediate server returned by each third server; and comparing whether enumeration results of the intermediate servers returned by the third servers are consistent, and if so, issuing the live video to the intermediate servers. If not, the total server may issue an alarm prompt to cause each third server to perform a resynchronization update, e.g., to request the intermediate server list and the intermediate server enumeration algorithm from the configuration management center, to ensure that the intermediate server list and the intermediate server enumeration algorithm of each third server are consistent.
In step S202, after receiving the live video pulling request sent by the viewing end, the edge server requests the enumeration result of the intermediate server from the third server cluster because the edge server does not maintain the intermediate server list and the enumeration algorithm of the intermediate server. Further, the edge server sends a request to each third server in the third server cluster to acquire an enumeration result of the intermediate server returned by each third server; comparing whether enumeration results of the intermediate servers returned by the third servers are consistent, and if so, pulling the direct broadcast video from the intermediate servers; if not, for example: and if the number of the intermediate servers enumerated by each third server is more than two, the edge server initiates polling to the more than two intermediate servers until the live video is pulled. Specifically, if the polled intermediate server has the live video, the live video is sent to an edge server; if the polled intermediate server does not have the live video, an error code is sent to the edge server.
In step S203, the edge server responds to the live video pulling request sent by the viewing end, and distributes the live video to the corresponding viewing end.
Further, the method also comprises the following steps: each third server in the third server cluster obtains a list of intermediate servers from the configuration management center and an intermediate server enumeration algorithm. The third server may periodically request a list of intermediary servers from the configuration management center and an intermediary server enumeration algorithm; or after the intermediate server list is changed or the enumeration algorithm is updated, the configuration management center synchronizes the changed intermediate server list or the updated enumeration algorithm to all the third servers. Since the number of third servers is far smaller than the number of total servers and edge servers, the third servers maintain the consistency of the intermediate server list and the enumeration algorithm, and the workload of synchronous work is greatly reduced.
The video live broadcast service method provided by the embodiment supports file type video live broadcast. The slicing of the live video stream may be done by an intermediate server. Specifically, after the total server sends the live video stream down to the intermediate server, the intermediate server performs slicing processing to convert the streaming video into a video file; the edge server pulls the video file from the intermediate server, the edge server has certain buffering capacity, and the pulled video file is buffered and then sent to the watching end.
The slicing of the live video stream may also be done by the third server. Specifically, after receiving the uploaded live video, the total server sends the live video stream to any third server, and the third server performs slicing processing to convert the streaming video into a video file. Then, the third server can return the video file to the total server, and the total server issues the video file to the intermediate server selected through enumeration; or the third server obtains the video file through slicing processing, and distributes the video file to the intermediate server directly after enumerating and selecting the intermediate server. The edge server pulls the video file from the intermediate server, the edge server has certain buffering capacity, and the pulled video file is buffered and then sent to the watching end.
In the present invention, the slicing process of streaming video may be performed with reference to one or more of the following ways:
in the first mode, a maximum slicing time length is set for streaming video in which audio always exists and video sometimes does not exist, if the maximum slicing time length is exceeded, slicing is forced, the slicing time length is prevented from being overlong, and a pure audio slicing file with overlong time length appears.
In a second mode, aiming at the scene that a player at some watching end can completely download slice files and start playing, the duration of the first few slice files of the streaming video is set to be shorter, if the duration of the first preset number of slice files is smaller than the preset duration, the first screen time is shortened, and the playing experience is improved.
In the third mode, for the same live broadcast slice, slice file information is read from the last slice index file m3u8 and updated to a new slice index file when the live broadcast slice is sliced again, so that a user can play the content in the shortest time without waiting for the new live broadcast slice, and the first screen time is shortened.
In a fourth mode, aiming at the situation that the same live broadcast abnormal current is cut off or the time stamp overflows and retreats, the watching end player cannot play the scene, the server end corrects by increasing the system time, and the time stamp is ensured to monotonically increase when the same slicing machine performs slicing; meanwhile, different slicing machines perform time synchronization through the NTP server, so that the time stamp is ensured to monotonically increase when the different slicing machines slice.
Mode five, under normal condition, the live broadcast of once is ended, just with the section index file uploading storage, in order to prevent that the section machine downtime from leading to the section index file to lose, and then lead to whole live broadcast video to be unable to broadcast, carry out regularly split index file, upload in real time, reduce the section index file and lose the risk.
In a sixth mode, when the slicing machine judges that the time stamp of a certain frame of the streaming video jumps, if the time stamp difference value of the previous frame and the next frame exceeds a preset time length, for example, 2s, forced slicing is performed, and discontinuous labels are written in the slice index file.
According to the video live broadcast service method provided by the invention, the third server cluster specially maintains the intermediate server list and the enumeration algorithm of the intermediate server, and the total server and the edge server do not need to maintain the intermediate server list and the intermediate server enumeration algorithm. Compared with the prior art, on one hand, the method decouples the relevance of data maintenance consistency between different server cluster levels (a total server cluster and an edge server cluster), and avoids the complexity of data consistency maintenance between two different server levels; on the other hand, the third server cluster is not a server for providing core video distribution service, the number of servers of the cluster is far smaller than that of service core servers such as a total server, an intermediate server and an edge server, and when the change condition of an intermediate server list or the upgrading condition of an enumeration algorithm occurs, the efficiency of realizing synchronous update of the third server cluster is very high; in still another aspect, the master server and the edge server can focus on the distribution of video files without starting an enumeration process, so that the video distribution efficiency in the live broadcast process is improved. In summary, the service performance of the video live broadcast service provided by the method is greatly improved.
The invention also provides a nonvolatile computer storage medium, wherein the computer storage medium stores at least one executable instruction, and the executable instruction can execute the video live broadcast service method in any method embodiment.
