Problems solved by technology

[0002] With the continuous innovation of camera devices in the technical field, the quality of video data is gradually improving. For video data with extremely high quality, if the order of playback is switched during playback, the video frames need to be re-decoded. Affected by network streaming and terminal decoding capabilities, it often takes a few seconds to wait, and the higher the quality of the video data, the longer the waiting time when switching between forward and backward playback, which greatly affects the video playback process. The smoothness of switching the playback order in the middle, in view of this, the video playback switching method needs to be improved urgently

Abstract

The invention discloses a video playing switching method, and the method comprises the following steps: sequentially acquiring and playing video frames from a playing queue according to a first playing sequence, wherein the frame serial numbers of all video frames in the current playing queue are arranged according to the first playing sequence; in response to completion of playing of the current video frame, inserting the current video frame into the end of a switching queue, wherein the frame serial numbers of all the video frames in the switching queue are arranged according to a first storage sequence; in response to the fact that the number of the video frames stored in the switching queue exceeds a threshold value, deleting the video frame farthest from the current video frame; and in response to a received instruction of switching the playing sequence, clearing all the video frames in the playing queue, adding at least part of continuous video frames in the switching queue into the playing queue according to a preset rule, and returning to the step of sequentially obtaining and playing the video frames from the playing queue according to the first playing sequence. According to the scheme, the fluency of switching the playing sequence in the video playing process can be improved.
