Abstract

The invention discloses a video synchronous playback method. The video synchronous playback method comprises the steps of: obtaining multi-channel videos to be synchronized; storing the play handle ofthe multi-channel videos in a video synchronous playback group corresponding to the multi-channel videos, so that the video synchronous playback group locates the play position of the multi-channel videos based on a reference video; and synchronously playing the multi-channel videos according to the play position of the multi-channel videos. The video synchronous playback group externally provides a uniform interface; uniform control of the multi-channel videos, including synchronous playing, synchronous locating to a certain time point, synchronous rapid playing and synchronous slow playing,in the video synchronous playback group can be realized; users do not need to manually adjust various videos; the video synchronous playback precision is improved; the difficulty of synchronous control on the multi-channel videos can be reduced; and the user experience can be improved. The invention further discloses a video synchronous playback device.

Description

technical field [0001] The present application relates to the field of video processing, and in particular to a video synchronous playback method and device. Background technique [0002] With the development of computer technology, network technology and multimedia technology, real-time video monitoring and monitoring video recording have been widely used in the field of security prevention and monitoring. At present, video recording playback in the general sense is playback of a single video file, and playback control such as start playback, pause playback, fast playback, and single-frame playback is performed on video playback. [0003] For some specific scenarios, such as the crime scene, it is necessary to play back the surveillance video at different points of the crime scene at the same time to achieve the purpose of restoring the real situation of the scene; for example, for the examination room and other scenes, it is necessary to play multiple angles of video at th...
