Abstract

Embodiments of the present application provide a video communication method, device, system, server, client, and storage medium. The video communication system includes: a server and multiple clients; the client is used to send video streams and / or audio to the server. Stream, wherein, the video stream includes a main video stream and / or a secondary video stream, and the secondary video stream is a video stream for operation demonstration; the server is used to obtain the data streams sent by each client; merge the data streams of each client, and Send the merged data stream to each client respectively. Through the video communication system of the embodiment of the present application, the client can send the video stream of the operation demonstration during the video communication process, so as to meet the diversity requirements of the video conference.

Description

Video communication method, device, system, server, client and storage medium technical field The application relates to the technical field of data transmission, particularly to video communication methods, devices, systems, servers, clients client and storage medium. Background technique [0002] With the development of Internet technology, the application of online video conferencing is becoming more and more frequent. In the related art, in the During a video conference, the client will combine the image data collected by the camera and the audio data collected by the microphone. Then send it to the server, the server merges the data streams of each client, and sends it to each client respectively, so as to realize Video conference communication. But in the above-mentioned communication process, the client only collects the image data collected by the camera and the data collected by the microphone. The audio data is merged and then sent to the server, which c...
