Embodiment 1
[0035] like figure 1 , an embodiment of the present invention provides a multi-channel video synchronous playback method, including:
[0036] Get multiple video files and user preset playback time;
[0037] Select the video file whose playback time overlaps with the playback time preset by the user as the candidate video file, display the candidate video file confirmed to be played by the user in the playlist as the to-be-played video file, and calculate the relative value of the to-be-played video file to the user. The offset time of the preset playback time;
[0038] Determine the number of videos to be played synchronously according to the number of to-be-played video files in the playlist, divide the screen into multiple play blocks, and call a video player of the format corresponding to the to-be-played video file for each play block;
[0039] Match the start time and offset time of each to-be-played video file from the playlist, obtain the playback content at each time...
Embodiment 2

Abstract
The invention discloses a multi-channel video synchronous playing method, system and device and a storage medium. The method comprises the following steps: acquiring a plurality of video files and playback time preset by a user; selecting video files of which the playing time is crossed with the playback time preset by the user as alternative video files, displaying the alternative video files confirmed to be played by the user in the playlist as video files to be played, and calculating offset time of the video files to be played relative to the playback time preset by the user; determining the number of videos to be played synchronously according to the number of the video files to be played in the playlist, dividing a screen into a plurality of playing blocks, and calling a video player in a format corresponding to the video files to be played for each playing block; and matching the start time and the offset time of each to-be-played video file from the playlist to obtain the playing content of each time point, and performing synchronous playing according to a time sequence. According to the invention, a plurality of videos with different time lengths and different formats can be played at the same time.
Description
technical field [0001] The invention relates to a multi-channel video synchronous playback method, system, device and storage medium, and belongs to the technical field of video processing. Background technique [0002] The video multi-channel monitoring solution can play the video streams generated by the multi-channel cameras in real time. The real-time playback is to passively accept the video stream data for playback. To achieve multi-channel playback during playback, it is generally required that all videos are recorded for 24 hours (possibly saved in segments), and it is assumed that all video files have the same start and end time, and then use the same timeline to play. [0003] If you play multiple videos with different lengths and overlapping time, you can only synchronize them manually. For example, in the office environment to monitor the desktop behavior and action behavior of the staff at the same time, the desktop operation time may be much less than the time...
