The singular terms "a" or "this" can also include plural forms.

[0028] like Figure 1 As shown, one embodiment of the present invention provides a streaming media forwarding method, the method comprising:

[0029] Step S110: Send the first streaming media data to the forwarding device and receive the second streaming media data from the publishing device. The first streaming media data is the previous streaming media data of the second streaming media data.

[0030] The technical solution of this embodiment can be implemented on a streaming media forwarding server to complete the transmission of streaming media data from the publishing device to the forwarding device.

[0031] Step S120: When the second streaming media data reception is completed, a data reception completion event is generated and sent to a preset publishing end through the network layer. The publishing end is used to put the second streaming media data into a preset forwarding queue when it receives the data reception completion event.

[0032] In this embodiment, the publishing end is an object created based on the publishing device. In this embodiment, the streaming media data publishing is triggered by a network layer data reception completion event when streaming media data reception is complete. In this embodiment, the data reception completion event is an asynchronous network event.

[0033] Step S130: When the first streaming media data is sent, a data transmission completion event is generated and sent to a preset forwarding end through the network layer. The forwarding end is used to retrieve the second streaming media data from the forwarding queue when it receives the data transmission completion event.

[0034] In this embodiment, the forwarding end is an object created based on the forwarding device. In this embodiment, when streaming media data transmission is complete, the network layer's data transmission completion event triggers the next streaming media data forwarding. In this embodiment, the data transmission completion event is an asynchronous network event.

[0035] Step S140: Send the retrieved second streaming media data to the forwarding device.

[0036] According to the technical solution of this embodiment, the asynchronous network events are fully utilized for streaming media forwarding, which can significantly reduce forwarding latency. At the same time, since no thread is needed for data forwarding, thread scheduling is reduced, resulting in higher forwarding performance and stronger concurrency capabilities.

[0037] like Figure 2 As shown, one embodiment of the present invention provides a streaming media forwarding method, the method comprising:

[0038] Step S210: Obtain the connection request command from the forwarding device through the network layer. The connection request command carries the flow identifier.

[0039] Step S220: When the session layer detects that the publishing end corresponds to the flow identifier, a forwarding end corresponding to the flow identifier is created.

[0040] In this embodiment, the connection request command is identified as originating from a forwarding device at the session layer. If no publishing end corresponding to the flow identifier is found, the creation of a forwarding end in the form of an object is cancelled. In this embodiment, the connection request command from the publishing device is also obtained through the network layer. When the connection request command is identified as originating from the publishing device at the session layer, a publishing end is created in the form of an object.

[0041] In this embodiment, the management of the session layer can be specifically as follows: Figure 3 As shown: Step S310, parse the connection request command. The connection request command includes information such as the stream ID (identifier) ​​and whether it is a publishing device. Determine whether the command comes from a streaming media publishing device or a receiving device based on the connection request command. If it is a publishing device, proceed to step S320; if it is a forwarding device, proceed to step S330. Step S320, create a publishing end object and save the publishing end and the corresponding stream ID record. Step S330, based on the stream ID, search for whether a publishing end exists in the created objects in the session management record. If it exists, proceed to step S340; otherwise, return an error to the requester. Step S340, create a forwarding end object and save the forwarding end and the corresponding stream ID record.

[0042] Step S230: Send the first streaming media data to the forwarding device and receive the second streaming media data from the publishing device. The first streaming media data is the previous streaming media data of the second streaming media data.

[0043] Step S240: When the second streaming media data reception is completed, a data reception completion event is generated and sent to a preset publishing end through the network layer. The publishing end is used to generate a second streaming media data object when it receives the data reception completion event. The second streaming media data object includes the second streaming media data and the identifier of the second streaming media data object, and puts the second streaming media data object into the forwarding queue.

[0044] Step S250: Determine whether there are multiple GOPs (a group of encoded frames containing a keyframe) corresponding to all streaming media data objects in the forwarding queue. If the determination result is yes, delete the streaming media data object corresponding to the non-latest GOP from the forwarding queue.

[0045] In this embodiment, only the streaming media data object corresponding to the latest picture group is retained in the forwarding queue to reduce the content of the forwarding queue, which is beneficial for the fast access of the forwarding queue.

[0046] In step S260, if the forwarding end is in a waiting state for data, the publishing end sends the second streaming media data to the forwarding end.

[0047] In this embodiment, when the forwarding end is in a waiting state for data, it means that the forwarding end has finished sending the previous streaming media data object. At this time, the publishing end will actively send the streaming media data object to the forwarding end.

[0048] In this embodiment, the process of publishing streaming media data can be specifically as follows: Figure 4 As shown: Step S410, after receiving the data reception completion event, the publishing end reads the received streaming media data from the receiving buffer according to the transmission protocol; Step S420, the publishing end creates a streaming media data object from the received streaming media data, which includes information such as stream ID, streaming media data, object identifier, reception time, and whether it is a keyframe; Step S430, the publishing end writes the streaming media data object into the streaming media sending queue corresponding to the stream ID, and the streaming media sending queue exists for each stream ID; Step S440, the streaming media information in the queue is counted to determine whether the stored streaming media information exceeds one GOP; Step S450, the streaming media data object corresponding to the earliest GOP in the queue is deleted; Step S460, if there is a forwarding end waiting for data, the latest data object is provided to the forwarding end.

[0049] Step S270: When the first streaming media data transmission is completed, a data transmission completion event is generated and sent to a preset forwarding end through the network layer. The forwarding end is used to obtain the second streaming media data object from the forwarding queue when it receives the data transmission completion event, and to obtain the second streaming media data from the second streaming media data object.

[0050] Specifically, the forwarding end determines the identifier of the second streaming media data object based on the known identifier of the first streaming media data object, and retrieves the second streaming media data object from the forwarding queue according to the identifier of the second streaming media data object.

[0051] In step S280, the forwarding end enters a data waiting state before retrieving the second streaming media data.

[0052] In this embodiment, when the forwarding end cannot obtain streaming media data from the forwarding queue, it enters a waiting data state, waiting for the publishing end to send streaming media data to it directly.

[0053] In this embodiment, the process of forwarding streaming media data can be specifically as follows: Figure 5 As shown: Step S510, retrieve the next unsent data object from the queue corresponding to the stream ID. The criterion for retrieving the next data object is the identifier of the data object that has been successfully sent last time. If the retrieval is successful, proceed to step S520; otherwise, jump to step S530. Step S520, write the streaming media data in the retrieved data object into the sending buffer and wait for the data to be sent. Step S530, the forwarding end switches to the waiting state for data and reactivates data forwarding after the publishing end has new data.

[0054] Step S290: Send the retrieved second streaming media data to the forwarding device.

[0055] Step S2100: Obtain timeout or connection disconnection events through the network layer.

[0056] Step S2110: When the session layer detects a timeout or connection disconnection event related to the publishing device, clear the publishing end and all forwarding ends corresponding to the publishing end.

[0057] Step S2120: When the session layer detects a timeout or connection disconnection event related to the forwarding device, the forwarding end is cleared, and the publishing end is cleared if there are no other forwarding ends corresponding to the publishing end.

[0058] In this embodiment, the process of handling timeout and connection disconnection events can be specifically as follows: Figure 6As shown: Step S610, after the network layer obtains the timeout and connection disconnection events, the session layer determines whether the event was caused by the publishing device or the forwarding device. If it was caused by the publishing device, proceed to step S620; if it was caused by the forwarding device, proceed to step S640. Step S620, release the publishing end object corresponding to the event (i.e., eliminate the publishing end). Step S630, based on the flow ID of the publishing end object released in S620, release all forwarding end objects with that flow ID. Step S640, release the forwarding end object corresponding to the event (i.e., eliminate the forwarding end). Step S650, based on the flow ID of the object, check whether there are other associated forwarding end objects for the publishing end of that flow ID. If not, proceed to step S660. Step S660, release the publishing end object corresponding to the flow ID of the forwarding object in S650.

[0059] In this embodiment, asynchronous network events at the network layer are used for streaming media forwarding. The network layer management work can be specifically described as follows: Figure 7 As shown: Step S710, start network port listening at the network layer; Step S720, set a new data receiving request at the network layer, and wait for the data from the publishing device to be received; Step S730, when the publishing device finishes pushing streaming media data, the network layer will trigger a data receiving completion event and send the event back to the publishing end for publishing; Step S740, set a new data sending request at the network layer, and wait for the data sent to the forwarding device to be sent; Step S750, when the data is successfully forwarded to the forwarding device, the network layer will trigger a data sending completion event and send the event back to the forwarding end to continue forwarding.

[0060] In summary, the technical solution of this embodiment provides a high-concurrency, low-latency streaming media forwarding method, which can be abstracted into a three-layer logical architecture, such as... Figure 8 As shown, the structure comprises a network layer, a publishing end and a forwarding end, and a session layer. The network layer receives and sends streaming media data and connection request commands, and sends callbacks to the session layer, the publishing end, and the forwarding end upon completion of connection, data reception, and transmission, respectively. The publishing end parses the received streaming media data and places the parsed data into a forwarding queue. The forwarding end retrieves the streaming media data from the forwarding queue and forwards it to the corresponding forwarding device. The session layer parses the connection request commands of the publishing device and the forwarding device to create publishing end and forwarding end objects, and eliminates the publishing end and the forwarding end upon timeout to disconnect the connection between the publishing device and the forwarding device. The high-concurrency, low-latency streaming media forwarding method provided in this embodiment can effectively solve the problems of insufficient concurrency, high latency, and insufficient smoothness in the streaming media forwarding process, achieving a better streaming media forwarding effect.
