Problems solved by technology

[0004] However, if the frame rates of the multi-channel cameras are inconsistent, that is, the frame intervals of the collected multi-channel videos are not equal, how to improve the playback synchronization of the multi-channel video playback is currently a problem that needs to be paid attention to and solved. The problem

Embodiment Construction

[0030] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the following will further describe the embodiments of the present application in detail in conjunction with the accompanying drawings.

[0031] For ease of understanding, some terms in the embodiments of the present application are explained first.

[0032] Frame rate: Each picture in the video is a frame, and the time of each picture is a frame time, that is, the picture in the video is in frames. The frequency (rate) at which images in frames appear successively on a display.

[0033] Frame Interval: The time interval between two consecutive frames.

[0034] Single frame: A still picture.

[0035] Next, some application scenarios involved in the embodiments of the present application are introduced.

[0036] At present, in more and more video capture scenarios, multiple cameras are used to capture video. After collecting multiple channels of vide...

Abstract

The embodiment of the invention discloses a video playing method and device and a computer readable storage medium, and belongs to the technical field of videos. In the embodiment of the invention, for the condition that frame rates of multiple videos are different, based on the time of the currently displayed last frame of picture, the reference time and the frame rates of the multiple videos, the first video of which the picture needs to be jumped in the multiple videos is determined; therefore, the time of the picture displayed by each video in the multiple videos after jump playing is closest to the reference time, namely, the time of the picture displayed by each video after jump playing is close, so that the multiple videos can be played relatively synchronously in time; in other words, the playing synchronism in time is improved when multiple videos are played back.

Description

technical field [0001] The embodiments of the present application relate to the field of video technology, and in particular, to a video playing method, device, and computer-readable storage medium. Background technique [0002] At present, in more and more video capture scenarios, multiple cameras are used to capture video. After collecting multiple channels of video, people can also search and observe the target person or event by synchronously replaying the multiple channels of video frame by frame. Wait. [0003] In the related art, by setting the frame rates of multiple cameras to be the same in advance, the frame intervals of the collected multiple videos are the same, that is, the frame rates of the multiple videos are the same. In this way, it takes the same time for each channel of video to play one frame, so that frame-synchronous playback of multiple channels of video can be achieved when playing back frame by frame. [0004] However, if the frame rates of the m...
