Referring to fig. 1, a schematic diagram of an implementation environment related to a multimedia data pushing method according to an embodiment of the present invention is shown, where the implementation environment may include: flow control node 110, push flow node cluster 120, flow state server 130, streaming media server 140, and streaming data storage system 150.
Wherein, the push flow node cluster 120 includes a plurality of push flow nodes having a function of normally pushing multimedia data. The stream data storage system 150 may include different types of databases, such as a relational database, a Key-Value database (Redis database), and a hard disk storage space.
It should be noted that the above-mentioned node may be a server, that is, the flow control node may be referred to as a flow control server, and the streaming node may be referred to as a streaming server, which is not specifically limited in this embodiment of the present invention.
The stream control node 110, the stream push node cluster 120, the stream state server 130, the streaming media server 140, and the stream data storage system 150 may be connected to each other through a wired network or a wireless network.
Referring to fig. 2, a flow chart of a multimedia data pushing method according to an embodiment of the present invention is shown, where the method can be applied to the stream control node 110 in fig. 1. It is noted that the present specification provides the method steps as described in the examples or flowcharts, but may include more or less steps based on routine or non-inventive labor. The order of steps recited in the embodiments is merely one manner of performing the steps in a multitude of orders and does not represent the only order of execution. In actual system or product execution, sequential execution or parallel execution (e.g., parallel processor or multi-threaded environment) may be possible according to the embodiments or methods shown in the figures. Specifically, as shown in fig. 2, the method may include:
s201, determining the stream storage address information matched with the target client.
The target client is a client for uploading the multimedia data stream to the streaming media server, and the target client can interact with the stream control node. For a live application scenario, the target client may be a live client.
In practical application, a corresponding relation table between the client identifier and stream storage address information may be pre-established, where the stream storage address information is address information which is provided to the client in advance before the client performs live broadcast and is used for storing a multimedia data stream provided by the client, and thus, the stream storage address information corresponding to the target client identifier may be determined by querying the corresponding relation table. In the architecture diagram shown in fig. 1, the stream storage address information may correspond to a designated storage space in the stream data storage system 150.
S203, sending the stream storage address information to a first target stream pushing node, so that the first target stream pushing node obtains the multimedia data stream of the target client according to the stream storage address information, and pushing the multimedia data stream to a streaming media server.
In this embodiment of the present specification, the first target push flow node is at least one push flow node in a push flow node cluster, and is preferably any one push flow node. The stream pushing nodes in the stream pushing node cluster have a function of normally pushing multimedia data, that is, the stream pushing nodes in the stream pushing node cluster are normal stream pushing nodes, if a certain stream pushing node fails and cannot push multimedia data, the stream pushing node can be kicked out of the stream pushing node cluster, and the stream pushing node can be added into the stream pushing node cluster again after the failure of the stream pushing node is eliminated.
In a specific embodiment, as shown in step S301 in fig. 3, the stream control node may determine, in response to a push stream request of a target client for a live data stream, stream storage address information of the live data stream matching the target client. That is to say, when a target client initiates a push stream request of a live data stream, the stream control node may determine, based on an identifier of the target client carried in the push stream request, stream storage address information of the live data stream corresponding to the identifier, where the stream storage address information of the live data stream is used to indicate a storage space a in which the live data stream of the target client is stored. Then, in step 303, the stream control node may send the stream storage address information of the live data stream to the first target stream pushing node, so that the first target stream pushing node obtains the live data stream from the storage space a according to the stream storage address information of the live data stream, and pushes the live data stream to the streaming media server. The streaming media server can send the corresponding live data stream to the audience client for playing based on the live data stream acquisition request sent by the audience client.
In practical application, under the influence of network stability, a live data stream of a target client may not be uploaded to a storage space a corresponding to stream storage address information of the live data stream in time, under such a situation, there may not be a corresponding live data stream in the storage space a, if a first target stream pushing node continues to acquire from the storage space a, the live data stream may not be acquired for pushing, so that a viewer client cannot play and blank the screen, and the live effect and the quality of live service are affected.
In view of this, in other embodiments, as shown in fig. 3, the stream control node may perform real-time monitoring on the live data stream in the storage space a, perform step S305, determine whether there is a live data stream in the storage space corresponding to the stream storage address information of the live data stream, and perform steps S307 to S309 if the determination result is no; step S307, determining the stream storage address information of the pre-stored data stream matched with the target client; step S309, sending the stream storage address information of the pre-stored data stream to the first target stream pushing node, so that the first target stream pushing node obtains a corresponding pre-stored data stream according to the stream storage address information of the pre-stored data stream, and pushes the pre-stored data stream to the streaming media server. Therefore, the method can ensure that the continuous multimedia data stream of the target client is pushed to the streaming media server in the live broadcast process, so that the corresponding audience client can uninterruptedly receive and play the corresponding multimedia data, thereby effectively avoiding the occurrence of a black screen and ensuring the quality and stability of the live broadcast effect and the live broadcast service.
The pre-stored data stream is a multimedia data stream pre-recorded by the target client, for example, the pre-stored data stream may be pre-recorded audio, video, and other data. To further improve the quality of the live service, the pre-stored data stream may be pre-recorded audio-video data associated with the live content of the live data stream. For example, for live broadcasting of a concert in city x with a star, the preset data stream may be a partially recorded video of a concert in city y before the star, or the like.
The stream storage address information of the pre-stored data stream is used for indicating a storage space B for storing the pre-stored data stream of the target client. The stream storage address information of the pre-stored data stream is different from the stream storage address information of the live data stream described above, i.e., the storage space a and the storage space B may correspond to two different storage spaces in the stream data storage system 150.
In another specific embodiment, the flow control node may further determine, in response to a stream pushing request of a target client for a pre-stored data stream, stream storage address information of the pre-stored data stream matching the target client. That is to say, when the target client directly initiates a stream pushing request for pre-storing the data stream, the flow control node may determine, based on the identifier of the target client carried in the stream pushing request, stream storage address information of the pre-stored data stream corresponding to the identifier, where the stream storage address information of the pre-stored data stream is used to indicate a storage space B in which the pre-stored data stream of the target client is stored. Also, the stream storage address information of the pre-stored data stream may be different from the stream storage address information of the live data stream, i.e. storage space a and storage space B may correspond to two different storage spaces in the stream data storage system 150.
According to the technical scheme of the embodiment of the invention, the stream storage address information of the target client is sent to at least one stream pushing node in the stream pushing node cluster through the stream control node, so that the problem that the multimedia data stream cannot be pushed due to the failure of the stream pushing equipment can be avoided, and the live broadcast effect in a live broadcast scene and the quality and stability of the live broadcast service are ensured. And stream storage address information is issued based on the stream control node, which can facilitate management and control of multimedia data streams.
In order to further ensure continuous pushing of the multimedia data stream and improve the pushing quality of the multimedia data stream, as shown in fig. 4, during the pushing of the multimedia data stream, the method may further include:
s401, acquiring a first streaming state of the multimedia data stream from a streaming state server at intervals of a preset time interval; the first streaming state is the state of the multimedia data stream determined by the streaming state server according to the heartbeat information reported by the first target streaming node.
In this embodiment of the present specification, when pushing a multimedia data stream to a streaming media server, a first target streaming node may obtain heartbeat information of the pushed multimedia data stream at every first preset time interval, where the heartbeat information includes a parameter for characterizing a pushing speed of the multimedia data stream, and for example, the heartbeat information may include a code rate, a frame rate, and the like of the pushed multimedia data stream. The first preset time interval may be set according to actual needs, and may be set to 1 second, 2 seconds, or the like, for example. The first target stream pushing node reports the acquired heartbeat information to the stream state server, and the stream state server can provide heartbeat service and state service, wherein the heartbeat service can determine a first stream state of the multimedia data stream according to the received heartbeat information of the multimedia data stream, and the state service can store the first stream state.
In practical application, when the state service stores the first flow state of the multimedia data flow, the state service may obtain a node identifier of a stream pushing node that pushes the multimedia data flow and a flow identifier of the multimedia data flow, and store a corresponding relationship between the node identifier, the flow identifier, and the first flow state. The node identification is used for uniquely determining a stream pushing node, and the stream identification is used for uniquely determining a multimedia data stream.
The flow control node may monitor the multimedia data stream pushed by the first target push streaming node, specifically, the first stream state of the multimedia data stream pushed by the first target push streaming node may be acquired from the stream state server at preset time intervals, where the preset time intervals may be set according to actual needs, for example, may be set to 1 minute, 2 minutes, and so on. In a specific embodiment, the stream control node may maintain a correspondence table between a stream identifier and a stream state of a multimedia data stream being pushed, where a stream state in the correspondence table may be updated according to a first stream state of the multimedia data stream obtained in actual pushing. The flow control node obtains the first flow state of the multimedia data flow corresponding to the flow identifier in the corresponding relation table every preset time interval by the flow state server, updates the flow state in the corresponding relation table to the current first flow state, and can record the current flow states of all pushed multimedia data flows through the corresponding relation table, so that the flow control node can conveniently perform corresponding control or management measures subsequently.
It is understood that the flow control node may acquire the first flow state by acquiring a node identifier corresponding to the flow identifier at the flow state server, and a corresponding relationship between the flow identifier and the first flow state.
S403, when the first flow state is a first preset flow state, determining a node state of the first target push flow node.
Specifically, the first streaming state of the pushed multimedia data stream may include a normal streaming state and an abnormal streaming state, where the normal streaming state refers to a state of the multimedia data stream when the heartbeat information meets a preset condition; the abnormal flow state refers to a state of the multimedia data flow when the heartbeat information does not meet a preset condition. The preset condition may be set according to actual parameters included in the heartbeat information, for example, the heartbeat information includes a code rate and a frame rate, the preset condition may be that the code rate is greater than a preset code rate threshold and the frame rate is greater than a preset frame rate threshold, both the preset code rate threshold and the preset frame rate threshold may be set according to actual conditions, and may be set to be zero or a number greater than zero, generally, the larger the preset code rate threshold and the preset frame rate threshold are set, the stricter the monitoring on the multimedia data stream is, and the better the monitoring on the pushed multimedia data stream is, the better the effect of the pushed multimedia data stream and the quality of the push service are guaranteed.
In this embodiment of the present specification, the first preset streaming state refers to an abnormal streaming state of a multimedia data stream, that is, when a first streaming state of a pushed multimedia data stream is an abnormal streaming state, a streaming control node needs to determine a node state of a first target streaming node that pushes the multimedia data stream. The flow control node may determine, based on the obtained correspondence between the node identifier, the stream identifier, and the first stream state, a first target stream pushing node that pushes the multimedia data stream in the abnormal stream state, and further determine a node state of the first target stream pushing node.
The node state of the first target push flow node may be, but is not limited to: the method comprises the steps that a flow control node obtains process information of a first target plug flow node, whether a push process of a multimedia data stream corresponding to an abnormal flow state exists in the process information is judged, when the judgment result is that the push process of the multimedia data stream corresponding to the abnormal flow state exists in the process information of the first target plug flow node, the abnormal flow state of the multimedia data stream is shown to be irrelevant to the process and is caused by equipment failure of the first target plug flow node, and at the moment, the node state of the first target plug flow node can be determined to be a second preset node state (namely equipment failure state); if the judgment result is negative, that is, if there is no multimedia data stream push process corresponding to the abnormal stream state in the process information of the first target push stream node, it indicates that the abnormal stream state of the multimedia data stream occurs because the corresponding push process is killed, and at this time, it may be determined that the node state of the first target push stream node is the first preset node state (that is, there is no corresponding push process state). That is, in the embodiment of the present specification, the preset node state may include a first preset node state and a second preset node state.

And the second target push flow node is at least one push flow node except the first target push flow node in the push flow node cluster.
In this embodiment, when determining that the node state of the first target stream pushing node is the preset node state (the first preset node state or the second preset node state), the flow control node may select a second target stream pushing node from the stream pushing node cluster, where the second target stream pushing node is different from the first target stream pushing node.
S407, taking the second target push flow node as the first target push flow node, and executing the step of sending the flow storage address information to the first target push flow node.
After determining a second target push flow node from the push flow node cluster, the second target push flow node may be used as a first target push flow node, and the foregoing step of sending the flow storage address information to the first target push flow node is executed, which is specifically referred to corresponding contents of the first target push flow node in the method embodiments shown in fig. 2 to fig. 4, and is not described herein again.
In practical applications, in order to improve the risk resistance of the push flow system and ensure the push quality of the multimedia data stream, as shown in a flow diagram of another multimedia data push method shown in fig. 5, the method further includes:
s501, receiving a second streaming status of the multimedia data stream sent by the streaming media server; the second streaming status is a status of the multimedia data stream determined by the streaming media server according to the received multimedia data stream.
In this embodiment, when receiving a multimedia data stream pushed by a stream pushing node, a streaming media server determines a second stream status of the multimedia data stream according to the received multimedia data stream, and sends the second stream status of the pair of media data streams to the stream control node. Specifically, the streaming media server may obtain heartbeat information of the received multimedia data stream, and determine a second streaming status of the corresponding multimedia data stream according to the heartbeat information, where the second streaming status, similar to the first streaming status, may include a normal streaming status and an abnormal streaming status. The normal stream state refers to a state of the multimedia data stream when the heartbeat information meets a preset condition; the abnormal flow state refers to a state of the multimedia data flow when the heartbeat information does not meet a preset condition. The preset condition may be set according to actual parameters included in the heartbeat information, for example, the heartbeat information includes a code rate and a frame rate, the preset condition may be that the code rate is greater than a preset code rate threshold and the frame rate is greater than a preset frame rate threshold, both the preset code rate threshold and the preset frame rate threshold may be set according to actual conditions, and may be set to be zero or a number greater than zero, generally, the larger the preset code rate threshold and the preset frame rate threshold are set, the stricter the monitoring on the multimedia data stream is, and the better the monitoring on the pushed multimedia data stream is, the better the effect of the pushed multimedia data stream and the quality of the push service are guaranteed.
Correspondingly, the stream control node receives a second stream state of the multimedia data stream sent by the streaming media server.
S503, judging whether the first flow state of the multimedia data flow is acquired, and executing the step S505 when the judgment result is negative; when the result of the determination is yes, the aforementioned step S403 is executed.
In practical applications, when the streaming state server fails, the streaming state server cannot provide the heartbeat service and the state service, and at this time, the streaming control node cannot acquire the first streaming state of the multimedia data stream from the streaming state server. In order to enhance monitoring on the multimedia data stream being pushed and ensure the pushing effect and the quality of the pushing service, in this embodiment of the present specification, the flow control node may determine whether a first stream state of the multimedia data stream is currently acquired, and if the determination result is negative, execute step S505; when the result of the determination is yes, the aforementioned step S403 is executed.
And S505, taking the second flow state as the first flow state, and executing the step of determining the node state of the first target push flow node when the first flow state is a first preset flow state.
When the stream control node determines that the first stream state of the pushed multimedia data stream is not acquired, in order to enhance monitoring of the multimedia data stream, the second stream state of the multimedia data stream received from the streaming media server may be taken as the first stream state, and the foregoing step S403 is executed, and when the first stream state is the first preset stream state, the node state of the first target stream push node is determined.
Referring to fig. 6, a flow chart of another multimedia data pushing method according to an embodiment of the present invention is shown, where the method can be applied to the system shown in fig. 1, and as shown in fig. 6, the method can include:
s601, the flow control node determines the flow storage address information matched with the target client and sends the flow storage address information to a first target flow pushing node; the first target push flow node is at least one push flow node in the push flow node cluster.
Correspondingly, the first target stream pushing node receives the stream storage address information of the target client sent by the stream control node.
S603, the first target stream pushing node acquires the multimedia data stream of the target client according to the stream storage address information, and pushes the multimedia data stream to a streaming media server.
In order to enhance the monitoring of the pushed multimedia data stream, in a specific embodiment, the multimedia data pushing method may further include steps S605 to S609:
s605, the first target stream pushing node reports the heartbeat information of the multimedia data stream to the stream state server.
In this embodiment of the present specification, when pushing a multimedia data stream to a streaming media server, a first target streaming node may obtain heartbeat information of the pushed multimedia data stream at every first preset time interval, where the heartbeat information includes a parameter for characterizing a pushing speed of the multimedia data stream, and for example, the heartbeat information may include a code rate, a frame rate, and the like of the pushed multimedia data stream. The first preset time interval may be set according to actual needs, and may be set to 1 second, 2 seconds, or the like, for example. And the first target stream pushing node reports the acquired heartbeat information to the stream state server.
Correspondingly, the stream state server receives heartbeat information reported by the first target stream pushing node.
S607, the stream state server determines the first stream state of the multimedia data stream according to the heartbeat information.
In this specification, a stream state server may provide a heartbeat service and a state service, where the heartbeat service may determine a first stream state of a received multimedia data stream according to heartbeat information of the multimedia data stream, and the state service may store the first stream state.
The first streaming state of the pushed multimedia data stream may include a normal streaming state and an abnormal streaming state, wherein the normal streaming state refers to a state of the multimedia data stream when the heartbeat information meets a preset condition; the abnormal flow state refers to a state of the multimedia data flow when the heartbeat information does not meet a preset condition. The preset condition may be set according to actual parameters included in the heartbeat information, for example, the heartbeat information includes a code rate and a frame rate, the preset condition may be that the code rate is greater than a preset code rate threshold and the frame rate is greater than a preset frame rate threshold, both the preset code rate threshold and the preset frame rate threshold may be set according to actual conditions, and may be set to be zero or a number greater than zero, generally, the larger the preset code rate threshold and the preset frame rate threshold are set, the stricter the monitoring on the multimedia data stream is, and the better the monitoring on the pushed multimedia data stream is, the better the effect of the pushed multimedia data stream and the quality of the push service are guaranteed.
S609, the flow control node acquires the first flow state from the flow state server at preset time intervals; when the first flow state is a first preset flow state, determining a node state of the first target flow pushing node; when the node state is a preset node state, determining a second target push flow node in the push flow node cluster; taking the second target flow pushing node as the first target flow pushing node, and executing the step of sending the flow storage address information to the first target flow pushing node; and the second target push flow node is at least one push flow node except the first target push flow node in the push flow node cluster.
In this embodiment of the present specification, the first preset streaming state refers to an abnormal streaming state of a multimedia data stream, that is, when a first streaming state of a pushed multimedia data stream is an abnormal streaming state, a streaming control node needs to determine a node state of a first target streaming node that pushes the multimedia data stream.
The preset node states of the stream pushing node may include a first preset node state and a second preset node state, where the second preset node state is an equipment failure state of the stream pushing node, and the first preset node state is a state where equipment of the stream pushing node is normal, but there is no process of pushing a corresponding multimedia data stream in process information of the stream pushing node.
In a specific embodiment, when the node state of the first target streaming node is the first preset node state, the flow control node may send the stream storage address information of the target client to the second target streaming node, and the second target streaming node may perform the corresponding action of the first target streaming node, that is, obtain the multimedia data stream of the target client according to the stream storage address of the target client, and push the multimedia data stream to the streaming media server. Meanwhile, when the node state of the first target stream pushing node is determined to be the first preset node state, the stream storage address information of the target client side is obtained from the target cache, and the multimedia data stream of the target client side is pushed again according to the stream storage address information. In practical applications, the crontab service of the first target push streaming node may determine, by a timing task, whether the node state of the first target push streaming node is in the first preset node state, where the crontab is used to set a command to be periodically executed, where the command reads an instruction from a standard input device and stores the instruction in a "crontab" file for later reading and execution, and specifically, in this embodiment, the "crontab" file includes an execution time interval and a specific execution command, where the executed command may be a script used to determine whether the node state of the first target push streaming node is in the first preset node state.
In another specific embodiment, when the node state of the first target streaming node is the second preset node state, the flow control node may send the stream storage address information of the target client to the second target streaming node, and the second target streaming node may perform the corresponding action of the first target streaming node, that is, obtain the multimedia data stream of the target client according to the stream storage address of the target client, and push the multimedia data stream to the streaming media server. When the second preset node state of the first target stream pushing node is eliminated, the first target stream pushing node can restart to operate, at the moment, the first target stream pushing node can acquire the stream storage address information of the target client from the target cache, and the multimedia data stream of the target client is pushed again according to the stream storage address information.
The target cache may be a key-value database (e.g., a Redis database) configured to store data information written by the first target streaming node when the first target streaming node pushes the multimedia data stream of the target client, where the data information may include stream storage address information of the target client, a node identifier (e.g., an IP address) of the first target streaming node, a timestamp, heartbeat information, and the like.
In practical application, before the first target streaming node re-pushes the multimedia data stream of the target client according to the stream storage address information, the first target streaming node may further determine whether a node identifier corresponding to the stream storage address information in the target cache is consistent with a current streaming node identifier, and whether a difference between the corresponding timestamp and the current timestamp satisfies a preset time condition, and only when the node identifier is consistent with the current streaming node identifier and the difference between the corresponding timestamp and the current timestamp satisfies the preset time condition, the multimedia data stream is pushed again. The preset time condition may be set according to actual needs, and may be set to not more than 1 minute, for example.
In the two specific embodiments, once the first target streaming node pushes the multimedia data stream of the target client according to the stream storage address information again, the same multimedia data stream is pushed by the two streaming nodes, in this case, the streaming node periodically obtains the node identifier corresponding to the multimedia data stream maintained in its own process, and compares the node identifier with the corresponding node identifier in the target cache, and if the node identifier and the node identifier are not consistent, the current streaming node abandons the pushing of the multimedia data stream of the target client and delivers the pushing to the other streaming node.
In order to further enhance the monitoring of the pushed multimedia data stream and improve the quality of the push service, in another specific embodiment, the multimedia data pushing method may further include steps S611 to S613:
s611, the streaming media server determines a second streaming state of the multimedia data stream according to the received multimedia data stream; sending a second flow state of the multimedia data flow to the flow control node.
