Problems solved by technology

However, for some fast-changing video images, such as tall buildings and football matches, if you still play at a frame rate of about 24 frames per second, you can feel the obvious jitter of the video image and poor fluency

Abstract

The invention provides a video playing method and device, and belongs to the technical field of videos. The method comprises the following steps: in a process of playing a video at a current frame rate, detecting a video picture difference between two adjacent frames to be played; when the video picture difference is greater than a preset difference threshold value, determining a target frame rate, when the target frame rate is greater than the current frame rate; generating a middle picture of the two adjacent frames according to the target frame rate; and inserting the middle picture between the two adjacent frames to play. Through adoption of the video playing method and device, the video picture difference between the two adjacent frames is detected to determine video frames which tend to jitter and have poor smoothness, and the middle picture can be generated dynamically according to actual conditions of the video frames in a playing process and is inserted between the two adjacent frames to play, so that the aim of increasing the frame rate adopted in playing is fulfilled; picture jittering is avoided; and the smoothness of a video picture is improved.

Description

technical field [0001] The present disclosure relates to the field of video technology, and in particular, to a video playing method and device. Background technique [0002] With the development of video technology, the frame rate used in video playback is getting higher and higher. For example, for human eyes, if the video frame rate is higher than 24 frames per second, the visual effect of the video screen will be relatively low. smooth effect. However, for some fast-changing video images, such as high-rise buildings and football matches, if they are still played at a frame rate of about 24 frames per second, the obvious jitter of the video image can be felt and the fluency is poor. To address this type of problem, related technologies can adopt a higher frame rate for video playback, such as 60 frames per second or 120 frames per second, so as to improve the fluency of video playback. Contents of the invention [0003] In order to overcome the problems existing in re...
