Problems solved by technology

[0003] In this way, if multiple video files need to be played simultaneously on one display screen (such as multiple monitoring images), if the resolutions of the video files are different, even if an instruction to start playing the multiple videos is sent at the same time, it may be difficult due to processing. Due to the difference in the processing time of the video file by the device, the multiple video files played on the display scr

Embodiment Construction

[0042] The specific embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present disclosure, and are not used to limit the present disclosure.

[0043] figure 1 It is a flowchart of a method for controlling video playback according to an exemplary embodiment of the present disclosure. Such as figure 1 As shown, the method includes step 101 to step 103.

[0044] In step 101, when a play instruction is received, the loading status of a video to be played is acquired, wherein there are at least two videos to be played. After receiving the play instruction, the video to be played needs to be decoded first, and then drawn. The drawing step is the process of presenting the video to the user. The decoding process consumes different decoding time due to the different resolution of the video to be played. Therefore...

Abstract

The disclosure relates to a video playback control method and a video playback control device, and relates to the field of video playback. The method comprises the following steps: when receiving a playback instruction, acquiring loading states of videos to be played, wherein there are at least two videos to be played; and when the loading states of the videos to be played are all the completion of loading, drawing the videos to be played. Through the above technical solution, only when the loading state of the decoding queue of each video to be played is the completion of loading, all the videos to be played are controlled to be drawn, that is, video pictures are presented to the user, so that the situation of asynchronous pictures of different videos caused by different decoding speeds of the videos to be played of different definitions can be avoided, and all the video files are started to be drawn at the same time, thereby making the files of all the videos to be played represent synchronized pictures in front of the user, and improving the user experience.

Description

Technical field [0001] The present disclosure relates to the field of video playback, and in particular, to a video playback control method and device. Background technique [0002] When a video file is played, it needs to be decoded by the processor before drawing can be started (that is, it is presented to the user). Generally, the decoding time consumed by the processor for video files of different resolutions is also different; video files with high resolution require longer decoding time than video files with low resolution. [0003] In this way, if you need to play multiple video files on one display screen at the same time (such as multiple monitoring screens), if the resolution of the video files is different, even if the instruction to start playing the multiple videos is sent at the same time, it may be due to processing The processing time of the video file by the device is different, so that multiple video files played on the display cannot be played simultaneously, wh...
