[0026] The following is a description of exemplary embodiments of the present disclosure in conjunction with the accompanying drawings, including various details of the embodiments of the present disclosure to facilitate understanding, which should be considered as merely exemplary. Therefore, it should be recognized by those of ordinary skill in the art that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted in the following description.

[0027] It should be noted that in the technical solution of the present disclosure, the collection, storage, use, processing, transmission, provision and disclosure of user personal information involved are in compliance with the provisions of relevant laws and regulations and do not violate public order and good morals.

[0028] In the related technology, after receiving the offer sent by the client, the server will first obtain the information of the corresponding live stream from the upstream server, and then send an answer to the client after parsing the media information of the stream. As a result, the client has to wait for a long time to obtain the answer, affecting the efficiency of media negotiation between the client and the server, which will increase the time it takes for the client to obtain the live media data stream and affect the start speed of the live broadcast.

[0029] In the disclosed embodiment, after receiving the first request for media negotiation sent by the first client, the first server can directly return a first response, thereby improving the efficiency of media negotiation between the first server and the first client, and can obtain live media data in parallel during the media negotiation process, thereby reducing data reflow delay and speeding up the start of live broadcast.

[0030] The following describes the live data reflow method, device, electronic device and storage medium of the embodiments of the present disclosure with reference to the accompanying drawings.

[0031] It should be noted that the executor of the live data reflow method of this embodiment is the first server end, which can be implemented by software and / or hardware. The first server end can be configured in an electronic device, and the electronic device may include but is not limited to a terminal, a server end, etc.

[0032] Figure 1 It is a flowchart of a live data reflow method provided according to an embodiment of the present disclosure.

[0033] like Figure 1 As shown, the live data reflow method includes:

[0034] S101: Receive a first request sent by a first client, wherein the first request includes multimedia protocol information supported by the first client and a first multimedia data identifier.

[0035] The live data reflow method in the embodiment of the present disclosure is specifically executed by the first server.

[0036] The first client refers to an electronic device used to present live media data, such as a mobile phone, a television, etc., and there is no limitation on this.

[0037] The first request refers to a request (offer) sent by the client and forwarded by the gateway for performing media negotiation with the first server.

[0038] Among them, media negotiation refers to the negotiation between the client and the server before starting to obtain media data to determine the encoding format, transmission protocol, bandwidth and other parameters that the communicating parties will use, thereby ensuring that the communicating parties can reach an agreement on the commonly supported media parameters, so that they can transmit and receive media data under the same media parameters and achieve effective and stable media data communication.

[0039] Among them, the multimedia protocol information supported by the first client refers to the Session Description Protocol (SDP) information containing its media capabilities (such as audio, video codecs, network transmission protocols, etc.), which includes: the media stream type (video or audio, etc.), transmission protocol, media format (different codecs) and other session and media stream parameters supported by the first client, without any restrictions.

[0040] The multimedia data is video stream data transmitted in Flash Video (FLV) format.

[0041] Among them, the first multimedia data identifier refers to the identifier of the first multimedia data to be presented by the first client, which can be, for example, the name of the live broadcast room, the link address of the live broadcast room, etc., and there is no limitation on this.

[0042] S102: Return a first response to the first client, wherein the first response includes a first content distribution network identifier allocated by the first server to the first client.

[0043] The first response is the SDP information generated by the first client after receiving the first request sent by the first server, that is, answer.

[0044] The answer is a response to the offer, indicating that the media parameter negotiation between the first server and the first client has been completed and subsequent media data communication can begin.

[0045] The first content delivery network identifier allocated to the first client includes: a content delivery network (Content Delivery Network, CDN) node identifier and a network port allocated by the server to the first client.

[0046] That is, in the embodiment of the present disclosure, after receiving the first request (offer) sent by the first client, the first server may generate a first response and return the first response to the first client via the gateway.
