Abstract: Techniques of streaming data processing for hybrid online meetings are disclosed herein. In one example, a method includes receiving, at the remote server, a video stream captured by a camera in the conference room. The video stream captures images of multiple local participants of an online meeting. The method also includes determining identities of the captured images of the multiple local participants in the received video stream using meeting information of the online meeting and generating a set of individual video streams each corresponding to one of the multiple local participants. The set of individual video streams can then be transmitted to the second computing device corresponding to a remote participant of the online meeting as if the multiple local participants are virtually joining the online meeting.
