Problems solved by technology

[0004] However, for video scenarios in different time zones, due to the time difference between different time zones, for example, 23:00 Beijing time and 10:00 New York time are actually the same time. As a result, videos in different time zones at the same moment cannot be played synchronously

Abstract

The embodiments of the present invention provide a video file synchronous playing method and device. The video file synchronous playing method includes the following steps that: at least two paths ofvideos to be played are parsed, wherein the videos to be played include time-zone time, and each video frame in the videos to be played contains the absolute time of the video frame; the current reference time of each path of video to be played is periodically calculated, wherein the current reference time of the video to be played is time is obtained by performing conversion calculation on the absolute time of a current video frame to be displayed in the video to be played according to the time-zone time in the video to be played; and the display of the current video frame to be displayed inthe video to be played is controlled according to the current reference time of each path of video to be played, so that the playing of each path of video to be played is synchronized. With the videofile synchronous playing method and device provided by the technical schemes of the invention adopted, the synchronous playing of videos in different time zones can be realized.

Description

Technical field [0001] The present invention relates to the technical field of video playback, in particular to a method and device for synchronous playback of video files. Background technique [0002] With the popularity of various multimedia players, playing audio and video and viewing pictures are the most widely used media execution methods. More and more players are pursuing the effect of multiple channels and synchronous playback, such as simultaneous playback on the same terminal 16 channels of video. In some scenes, the video resolution is high or the number of channels that need to be opened is very large, there will be performance problems that cause the video to freeze or delay. In this way, a synchronization technology is needed to keep multiple channels of video playing synchronously. [0003] In related technologies, different types of videos are identified, encoded, and extracted in a preset storage space, played synchronously on the time axis in a video playback s...
