Abstract

The invention discloses a whiteboard and video synchronization method and device, computing equipment and a storage medium. The method comprises the following steps: first terminal equipment acquiresa video stream sent by a server, each frame of video data in the video stream is provided with a timestamp, and the video stream is sent to the server after the second terminal equipment collects eachframe of video data and adds the timestamp for each frame of video data, and then the video stream is played; and the whiteboard content corresponding to the timestamp of the played current frame ofthe video stream is acquired from the cache so as to perform synchronous display. Since the timestamp is used as a synchronization object, the whiteboard content and the video data of the current frame with the same timestamp are synchronously displayed, and the problem that the whiteboard content and the video data are asynchronous due to unstable network in the prior art can be solved.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of streaming media, in particular to a method, device, computing device and storage medium for synchronizing a whiteboard and video. Background technique [0002] In recent years, with the rapid growth of Internet users and the continuous support of national education policies, the online education industry has developed rapidly. China's online education has gone through three stages: from distance education platforms and training institutions to the front line to the current Internet companies. The Internet has brought significant changes to education. This change is not only reflected in the breakthrough of time and space, but also in multiple aspects of education such as teaching, learning, evaluation, and testing. [0003] With the rapid development of the online education industry, whiteboard interactive services on the network platform have also emerged as the times require. ...
