Abstract

The embodiment of the invention provides a video communication method, a device, a system, a server, clients and a storage medium. The system comprises the server and a plurality of clients. Each client is used for sending a video stream and / or an audio stream to the server, the video stream comprises a main video stream and / or an auxiliary video stream, and the auxiliary video stream is a video stream for operation demonstration; the server is used for acquiring data streams sent by each client; and merging the data streams of the clients, and sending the merged data streams to the clients respectively. According to the video communication system provided by the embodiment of the invention, the client can send the video stream for operation demonstration in the video communication process, so that the requirement of diversity of video conferences is met.

Description

technical field [0001] The present application relates to the technical field of data transmission, in particular to a video communication method, device, system, server, 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 related technologies, during a video conference, the client will combine the image data collected by the camera and the audio data collected by the microphone, and then send it to the server, and the server will combine the data streams of each client and send them to each client terminal, so as to realize video conference communication. [0003] However, in the above communication process, the client only combines the image data collected by the camera and the audio data collected by the microphone, and then sends them to the server, which cannot meet the needs of video conference diversity.
