Abstract: A video conference recording method, device, and system, which can implement recording and playback of a video of a conference according to a user requirement when the video conference is in progress. The method includes receiving a playback request message input by a user; sending the playback request message to a recording server, so that the recording server selects recorded streaming media information according to the playback request message; receiving a combination data stream sent by the recording server, where the combination data stream includes at least one channel of the streaming media information that is selected, and each of the at least one channel of the streaming media information is corresponding to one conference site; and displaying the at least one channel of the streaming media information that is received. The embodiments of the present invention are used to implement recording of a video conference.
