Problems solved by technology

In other words, the viewer always passively accepts the changes of the picture, but cannot actively control the speed, direction and angle of the picture change
Therefore, when watching a video, the sense of substitution that the viewer can produce is relatively limited. If you want the viewer to intuitively feel the scene and experience of the shooter at that time, you need very high shooting and film and television skills. For video shooters, it is difficult to achieve

Abstract

The invention discloses a video playing controller and control method based on mobile device rotation detection. The playing controller comprises a rotation detection module which is used for collecting posture data of rotating a mobile device in a video file playing process and sending the posture data to the video playing module, wherein the posture data comprises a rotation direction and angle;and the video playing module which is used for receiving the posture data and playing a video file according to the posture data, thereby controlling playing progress, direction and speed of the video file. According to the controller and the method, the skip of video frames is controlled according to the rotation of the mobile device in the playing process, a fluency demand in the video playingprocess is satisfied, and moreover, the operation quantity of the mobile device is reduced. The playing of the video is controlled by rotating the mobile device, so the enjoyment of watching the videoby a user is improved.

Description

technical field [0001] The present invention relates to the technical field of video processing, in particular to a video playback controller and control method based on mobile device rotation detection. Background technique [0002] Existing video playback technologies all play a group of continuous pictures in chronological order. For the viewer, although they can feel the visual experience brought by the dynamic picture, the speed, direction, angle, etc. of the picture change are not controlled by the viewer, but are preset by the video shooter when shooting. OK In other words, the viewer always passively accepts the changes of the picture, but cannot actively control the speed, direction and angle of the picture change. Therefore, when watching a video, the sense of substitution that the viewer can produce is relatively limited. If you want the viewer to intuitively feel the scene and experience of the shooter at that time, you need very high shooting and film and tele...
