Description

Video subscription processing method and related device Technical Field The embodiment of the application relates to the technical field of data processing, in particular to a video subscription processing method and a related device. Background The SFU architecture (SELECTIVE FORWARDING UNIT) is an architecture that routes and forwards client audio-video data streams through a server. In the architecture, the server is mainly responsible for forwarding media or storage media without directly performing higher-computation-power requirements such as encoding, transcoding, decoding, mixing and the like, and the SFU architecture is commonly used for network architectures in video conferences and real-time communication systems and is widely applied to scenes such as multi-person video calls, live broadcasting, online education and the like. Under the SFU architecture, the video receiving end subscribes to the video by sending a subscription request to the server, wherein the subscription request comprises the identification of the video sending end, the resolution of the video sending end, the frame rate of the video sending end and the bit rate of the video sending end. When the server receives the subscription requests, the server forwards all the subscription requests to the sending end of the video sending end, and the video sending end decides what video picture to send according to the subscription requests. At present, the server in the scheme of the prior art is only used for forwarding the subscription request sent by the video receiving end to the video sending end, and does not process the subscription request, when the number of the session increases, the server needs to process a large number of subscription requests at the same time, so that the server needs to process and forward the subscription request frequently, and when a plurality of video receiving ends initiate subscription to the same video sending end, the video sending end can process calculation of three dimensions of resolution, frame rate and bit rate in all the subscription requests frequently, so as to determine the resolution, frame rate and bit rate of the video to be sent, and further the processing efficiency of the subscription request is reduced. Disclosure of Invention The embodiment of the application provides a video subscription processing method and a related device, wherein the subscription processing method comprises the steps of dividing and processing a subscription request total set according to a first subscription parameter and a second subscription parameter to obtain a second request set, and then sending the second subscription request set to a corresponding video sending end to obtain a video corresponding to the second subscription request set. The embodiment of the application provides the following technical scheme: In a first aspect, an embodiment of the present application provides a method for subscription processing of video, where the method includes: Acquiring a plurality of first subscription requests sent by a plurality of video receiving terminals, wherein the first subscription requests comprise first subscription parameters, second subscription parameters and information of subscribed video sending terminals; classifying a plurality of first subscription requests in a fixed time period according to subscribed video sending terminals to obtain a first subscription request set, wherein one first subscription request set corresponds to one video sending terminal; Classifying a plurality of first subscription requests in a first subscription request set according to the first subscription parameters to obtain a subscription request subset; Dividing the subscription request subset into a plurality of subscription request groups according to the second subscription parameters; Aggregating all first subscription requests in the subscription request group into second subscription requests, wherein one second subscription request corresponds to one subscription request group; constructing a second subscription request set according to the second subscription requests, wherein the second subscription request set comprises all second subscription requests corresponding to the same video sending end; and sending the second subscription request set to a corresponding video sending end, and obtaining videos corresponding to the second subscription request set. In some embodiments, the method is applied to a server, the server is respectively connected with a video receiving end and a video sending end, and sends a second subscription request set to a corresponding video sending end, and obtains a video corresponding to the second subscription request set, including: The second subscription request set is sent to the video sending end, so that the video sending end returns the corresponding video according to the second subscription request set; and after receiving the video sent by the video sending end, sen
