The plurality of stream pushing ends are used for pushing the respective stream media files to the stream media server.
The streaming media server comprises a plurality of virtual streaming slots, and the plurality of virtual streaming slots and the plurality of streaming ends have an association relationship.
The application server is used for receiving a switching instruction, determining a first virtual push flow slot indicated by the switching instruction, determining a first push flow end having a correlation with the first virtual push flow slot, generating a signaling according to the determined first push flow end, and sending the signaling to the streaming media server;
the streaming media server is used for switching the streaming media data currently pushed to the CDN node into the streaming media data of the first pushing end according to the signaling.
In this embodiment, because the plurality of stream pushing ends and the plurality of virtual stream pushing slots have an association relationship, the streaming media server can receive the streaming media data of the plurality of stream pushing ends at the same time and distinguish the stream media data by the corresponding virtual stream pushing slots; after the first stream pushing end is determined according to the switching instruction, the stream media servers can directly switch the stream media data pushed to the CDN node into the stream media data of the first stream pushing end due to the fact that the stream media servers already push the respective stream media data to the stream media servers, seamless switching of the stream media data of the plurality of stream pushing ends is achieved, a live broadcast process does not need to be suspended, switching efficiency of the stream pushing end switching is improved, and user experience is improved.
Specifically, referring to fig. 2, an embodiment of the present application provides a stream pushing method applied to a multimedia server of the above stream pushing system, where as shown in the figure, the stream pushing method includes:
s201, receiving a switching instruction, determining a first virtual push flow slot indicated by the switching instruction, and determining a first push flow end having a correlation with the first virtual push flow slot.
In this embodiment, the streaming media server includes a plurality of virtual stream pushing slots, the plurality of virtual stream pushing slots and the plurality of stream pushing ends have an association relationship, and the stream pushing ends can push respective streaming media data to the streaming media server.
In this embodiment, the flow pushing end may include, but is not limited to, at least one of the following: cell phones, pads, PCs, televisions and other electronic devices with multimedia transmission capabilities. The plurality of push flow ends may be the same or different, and this embodiment does not limit this.
In this embodiment, the streaming media data at the stream pushing end may include at least one of the following: video stream data (e.g., desktop shared data, shot data of a camera), audio stream data, text data.
The virtual stream pushing slot having an association relationship with the stream pushing end can be used for distinguishing a plurality of stream pushing ends, and particularly can be used for distinguishing stream media data of the plurality of stream pushing ends. After the streaming media server receives the switching instruction, the first virtual push flow slot indicated by the switching instruction may be determined, and a first push flow end having a relationship with the first virtual push flow slot may be further determined.
For example, the plurality of virtual push slots may have different slot identifiers, and after determining the association relationship between the push end and the virtual push slot, the slot identifiers of the virtual push slot may be added to the streaming media data of the push end, so as to distinguish the streaming media data of the plurality of push ends through the slot identifiers. The switching instruction may include a slot identifier of the first virtual push flow slot, and thus it may be determined that the streaming media data carrying the slot identifier of the first virtual push flow slot is streaming media data of the first push flow end. Of course, the above description is only for illustration, and the present embodiment does not limit this.
S202, generating a signaling according to the determined first stream pushing end, and sending the signaling to a stream media server, so that the stream media server switches the stream media data currently pushed to the CDN node into the stream media data of the first stream pushing end.
Specifically, a CDN (Content Delivery Network) is an intelligent virtual Network built on the basis of an existing Network, and by means of edge servers deployed in various places, users can obtain required Content nearby through functional modules of load balancing, Content Delivery, scheduling and the like of a central platform, so that Network congestion is reduced, and the access response speed and hit rate of the users are improved. The key technology of the CDN is mainly content storage and distribution technology.
The CDN includes a plurality of nodes, and each server or each group of servers may be a node of the CDN. The attribute information of the CDN node may include an address, an index, timeout setting, and the like of the CDN node, and pushing a stream to the CDN node may be implemented by obtaining the attribute information of one CDN node.
In this embodiment, because the streaming media server can receive the streaming media data of the plurality of streaming clients and distinguish the streaming media data by the virtual streaming slots, when step S202 is executed, the streaming media data can be directly switched, that is, the streaming media data currently being streamed to the CDN node is switched to the streaming media data of the first streaming client, thereby implementing seamless switching of the streaming media data of the plurality of streaming clients, without suspending a live broadcast process, improving switching efficiency of switching the streaming clients, and improving user experience.
Referring to fig. 3, an embodiment of the present application provides a plug flow method, as shown in the figure, the method includes:
s300, the user registers an account number in the live broadcast platform and opens the live broadcast related service.
S301, acquiring a live broadcast room creating instruction.
In this embodiment, after the user registers the account number in the live broadcast platform, the user can apply for creating the live broadcast room in the live broadcast platform by means of the registered account number, and at this time, the browser or the client of the terminal where the user is located can send a live broadcast room creation instruction to the application server of the platform.
In this embodiment, the application server is configured to provide support for operations of the user other than the audio/video operation. Such as login operation of logging in a live broadcast platform, operation of creating a live broadcast room, operation of editing the live broadcast room, operation of deleting the live broadcast room, and the like.
S302, creating a live broadcast room, and determining a plurality of virtual push flow slots of the live broadcast room.
In this embodiment, the process of creating the live broadcast room is executed by the application server, and the created live broadcast rooms may be divided into two types, namely, a host live broadcast room and a common live broadcast room. It should be noted that the virtual push stream slot only exists in the host live broadcast room, and does not exist in the normal live broadcast room.
The step S302 is directed to the host live broadcast room, and when the live broadcast room creation instruction indicates creation of the host live broadcast room, the application server may complete corresponding live broadcast room creation operation according to the live broadcast room creation instruction, and default that the host live broadcast room includes a preset number (for example, three) of virtual push stream slots.
For example, one host live room may include three virtual push streams slots.
When the live broadcast room creation instruction indicates that a common live broadcast room is created, the application server does not determine a plurality of virtual live broadcast slots of the live broadcast room. Only one live broadcast room is created, the control authority of the live broadcast room is directly given to a live broadcast instructor, and the live broadcast instructor controls the start and the end of live broadcast and recording.
S303, receiving live broadcast requests of a plurality of stream pushing ends, and establishing an association relation between the stream pushing ends and the virtual stream pushing slots.
In this embodiment, the live broadcast request may be a live broadcast request requesting to log in to a live broadcast room, or may also be an invitation request requesting a live broadcast from a stream pushing end, and the like.
Different users can correspond to different login addresses when logging in the live broadcast room, and in order to distinguish whether the users log in the live broadcast room are ordinary viewers (such as students) or lectors or presenters and the like, the live broadcast platform can set different login addresses for different roles. And determining that the user is a lecturer or a host and the like according to the login address input by the user during login, and then establishing that the user is a stream pushing end, and at the moment, establishing the association relationship between the stream pushing end and the virtual stream pushing slot.
Specifically, the virtual push flow slot may include < publisher _0, { id0, name0} >, where publisher _0 is a slot identifier of the virtual push flow slot, and { id0, name0} is a push flow end identifier of the virtual push flow slot. The ID value and name of the plug end having a relationship with the virtual plug slot may be recorded in the plug end identifier.
Before the incidence relation between the plug flow end and the virtual plug flow end is established, the plug flow end mark in the virtual plug flow groove can be empty. And establishing an incidence relation, namely determining the plug flow end identification of the virtual plug flow groove.
Specifically, in this embodiment, the association relationship between the plurality of stream pushing terminals and the plurality of virtual stream pushing slots may be established according to a login sequence of the plurality of stream pushing terminals logging in the live broadcast room.
For example, after establishing a live broadcast Room, determining a stream push end list from _ online _ publishing _ roomld of the live broadcast Room:
<publisher_0,{id0,name0}>
<publisher_1,{id1,name1}>
<publisher_2,{id2,name2}>
after the initial creation is completed, the three virtual push flow slots are publisher _0, publisher _1 and publisher _2 respectively, and the push flow ends of the three virtual push flow slots are marked as empty.
After receiving a live broadcast request of a stream pushing end of an instructor a, determining that a first virtual stream pushing slot is empty, and filling the id and the name of the instructor a into the first virtual stream pushing slot, namely:
< publicher _0, { id0, name0} > < publicher _0, { idA, a } >; then, receiving a live broadcast request of instructor B, wherein the first virtual push stream slot is not empty, and the second virtual push stream slot is empty, filling the id and name of instructor B into the second virtual push stream slot, that is, < publish _1, { id1, name1} >, i.e., the name of instructor B is not empty, and the second virtual push stream slot is not empty, but the first virtual push stream slot is not empty
< publish _1, { idB, B } >, and so on until all virtual push stream slots are filled, or until no more live requests are received from the push stream side.
S304, returning the push address corresponding to the virtual push slot to the associated push end.
In this embodiment, each virtual push flow slot may correspond to a push flow address, for example, the push flow address of the first virtual push flow slot may be, for example: rtmp: // xxx roommid — 0, the push flow address of the second virtual push flow slot may be, for example: rtmp: // xxx roommid _1, the push flow address of the third virtual push flow slot may be, for example: rtmp: // xxx roommId _ 2.
Specifically, when a certain stream pushing end performs stream pushing, a stream pushing request may be sent to an application server of the live broadcast platform, and the application server of the live broadcast platform determines that an operation corresponding to the stream pushing request relates to an operation related to an audio/video data stream, and then may generate and send a signaling to the stream media server according to a stream pushing address corresponding to the stream pushing end, so as to control the stream media server to implement stream pushing.
Optionally, in any embodiment of the present application, the streaming media server is connected to the plurality of stream pushing terminals through a gateway, and the stream pushing terminals push respective streaming media data to the streaming media server through the gateway. Therefore, the streaming media data of each push stream end can be converted through the gateway, and the streaming media data suitable for being pushed by the CDN node is obtained.
Specifically, as shown in fig. 4, instructor A, B, C may be communicatively coupled to a streaming server via a gateway and may provide live services via an application server.
Instructor a has an association with the 0 slot, instructor B has an association with the 1 slot, and instructor C has an association with the 2 slot. The 0 slot defaults to the talkback slot.
S305, adding the slot position identification of the virtual push flow slot to the streaming media data of the push flow end corresponding to the push flow end identification according to the push flow end identification of the virtual push flow slot.
By providing different stream pushing addresses corresponding to the virtual stream pushing slots for the plurality of stream pushing ends, the multimedia server can directly add slot position marks to the stream media data obtained by each stream pushing address, and the slot position marks are distinguished. Exemplary, by rtmp: // xxx roommid _0, since rtmp: if// xxx _ roommid _0 corresponds to the first virtual push slot, the streaming media data corresponding to instructor a may be directly added with the slot identifier publisher _0 of the first virtual push slot.
In this embodiment, after receiving the signaling of the application server, the streaming media server may determine a slot identifier corresponding to the signaling, and push streaming media data having the slot identifier to the CDN node. For the CDN node, the received streaming media data are all pushed by the streaming media server, so that when the pushing end is switched, live broadcasting does not need to be interrupted, thereby implementing seamless switching of the streaming media data of multiple pushing ends.
The streaming media server can also perform operations such as recording, transcoding and the like according to requirements for subsequent watching and playback.
In this embodiment, after the step S305 is completed, the streaming media data corresponding to the first virtual push flow slot may be defaulted as the streaming media data pushed to the CDN node. Of course, the above description is only for illustration, and the present embodiment does not limit this.
Specifically, the virtual pushing chute can be divided into a talkback chute and a common chute; the main speaking groove represents a virtual pushing groove corresponding to streaming media data pushed to the CDN node, and other virtual pushing grooves except the main speaking groove are common grooves.
The main speaking slot can be stored in a cache database Redis, and the specific storage structure is as follows:
Room_speaker_roomId:<pitId,id>
wherein, pitId is a slot position identification of the virtual pushing flow slot, and id is a pushing flow end id of the virtual pushing flow slot. The virtual pushout slot identified by pitId is the talkback slot.
S306, receiving a switching instruction, and determining a first virtual pushing flow slot indicated by the switching instruction.
Illustratively, the default keyer slot is a 0 slot, at which time the keyer slot stores data as follows:
Room_speaker_roomId:<0,idA>；
when the live broadcast is started, a network request is sent to the streaming media server, and the streaming media server forwards the streaming media data of the 0 slot to the CDN node after receiving the request.
Optionally, in any embodiment of the present application, the method further includes: and the stream pulling end pulls the stream media data provided by the CDN node to the local so as to carry out live broadcast according to the stream media data. That is, the viewing end pulls up the stream from the CDN node for viewing.
The home slot may be maintained by the application server.
Specifically, when the step S306 is executed, the application server may receive the switching instruction, and generate and send a signaling indicating to switch the talkback slot to the streaming media server according to the switching instruction. For example, if the application server determines that the switching instruction indicates to switch the lecturer B to the main speech, then determines that the virtual push flow slot of the lecturer B is the first virtual push flow slot, then the application server only needs to send a signaling to the streaming media server, and the indicator changes the main speech slot data in the Redis as follows:
Room_speaker_roomId:<0,idA>--->Room_speaker_roomId:<1,idB>；
and after the change is finished, the streaming media server pushes the stream according to the changed Redis. Specifically, as shown in fig. 5, the master slot after switching is 1 slot.
In addition, as shown in fig. 5, the system may further include a cache database for caching the slot information of the virtual push flow slot and the instructor-related information.
Optionally, in this embodiment, before switching, a hosting mode of the live broadcast room may be determined, where the hosting mode includes a client mode and a web page mode; if the host mode is a webpage mode, receiving the switching instruction sent from a host client; or, if the host mode is a client mode, receiving the switching instruction sent from the stream pushing end.
Specifically, the hosting mode can be classified into two types, a web mode and a client mode.
If the host mode is a webpage mode, the login address of the host is represented as a webpage, the host completes corresponding host operations through the browser, such as operations of starting live broadcasting, stopping live broadcasting, switching a main speaker and the like, all operations are completed by the host, a lecturer cannot participate in the operations, but the operations are limited by the browser, so that the client where the host is located cannot perform stream pushing, namely the host does not directly start live broadcasting, and the client where the host is located does not serve as a stream pushing end to establish an association relationship with the virtual stream pushing slot in the webpage mode.
Compared with a webpage end, the client can set a more complex processing flow, so that if the host mode is the client mode, the stream pushing end can directly serve as a host, an application program client installed in the stream pushing end can directly verify whether the stream pushing end has the switching authority, the workload of a server cannot be increased, namely, the stream pushing end can be reused as a host client for controlling the flow of the live broadcast room in the client mode.

Thus, particular embodiments of the present subject matter have been described. Other embodiments are within the scope of the following claims. In some cases, the actions recited in the claims can be performed in a different order and still achieve desirable results. In addition, the processes depicted in the accompanying figures do not necessarily require the particular order shown, or sequential order, to achieve desirable results. In some embodiments, multitasking and parallel processing may be advantageous.
In the 90 s of the 20 th century, improvements in a technology could clearly distinguish between improvements in hardware (e.g., improvements in circuit structures such as diodes, transistors, switches, etc.) and improvements in software (improvements in process flow). However, as technology advances, many of today's process flow improvements have been seen as direct improvements in hardware circuit architecture. Designers almost always obtain the corresponding hardware circuit structure by programming an improved method flow into the hardware circuit. Thus, it cannot be said that an improvement in the process flow cannot be realized by hardware physical modules. For example, a Programmable Logic Device (PLD), such as a Field Programmable Gate Array (FPGA), is an integrated circuit whose Logic functions are determined by programming the Device by a user. A digital system is "integrated" on a PLD by the designer's own programming without requiring the chip manufacturer to design and fabricate application-specific integrated circuit chips. Furthermore, nowadays, instead of manually making an Integrated Circuit chip, such Programming is often implemented by "logic compiler" software, which is similar to a software compiler used in program development and writing, but the original code before compiling is also written by a specific Programming Language, which is called Hardware Description Language (HDL), and HDL is not only one but many, such as abel (advanced Boolean Expression Language), ahdl (alternate Hardware Description Language), traffic, pl (core universal Programming Language), HDCal (jhdware Description Language), lang, Lola, HDL, laspam, hardward Description Language (vhr Description Language), vhal (Hardware Description Language), and vhigh-Language, which are currently used in most common. It will also be apparent to those skilled in the art that hardware circuitry that implements the logical method flows can be readily obtained by merely slightly programming the method flows into an integrated circuit using the hardware description languages described above.
The controller may be implemented in any suitable manner, for example, the controller may take the form of, for example, a microprocessor or processor and a computer-readable medium storing computer-readable program code (e.g., software or firmware) executable by the (micro) processor, logic gates, switches, an Application Specific Integrated Circuit (ASIC), a programmable logic controller, and an embedded microcontroller, examples of which include, but are not limited to, the following microcontrollers: ARC 625D, Atmel AT91SAM, Microchip PIC18F26K20, and Silicone Labs C8051F320, the memory controller may also be implemented as part of the control logic for the memory. Those skilled in the art will also appreciate that, in addition to implementing the controller as pure computer readable program code, the same functionality can be implemented by logically programming method steps such that the controller is in the form of logic gates, switches, application specific integrated circuits, programmable logic controllers, embedded microcontrollers and the like. Such a controller may thus be considered a hardware component, and the means included therein for performing the various functions may also be considered as a structure within the hardware component. Or even means for performing the functions may be regarded as being both a software module for performing the method and a structure within a hardware component.
