Video multi-speed playing method and system based on voice

Abstract

The invention discloses a video multi-speed playing method and system based on voice. When a video file is preprocessed, the method comprises the steps that A, voice information in the video file is read; B, analyzing the voice information, decomposing the video file into a plurality of sub-videos according to the speed of the voice information, and obtaining the speed multiplication rate of eachsub-video segment based on the corresponding voice information; C, forming a speed multiplication description file by utilizing the speed multiplication rate corresponding to each sub video segment; when the video file is played, the method comprises the following steps: step D, loading and analyzing a speed multiplication description file; and step E, when the video file is played to a certain sub-video segment, playing the video file according to the speed rate corresponding to the sub-video segment in the speed description file. According to the method, the speed multiplication rate can beautomatically calculated through the voice in the video, so that a user can watch the complete video at the most appropriate speed multiplication rate which is intelligently changed, the speed multiplication rate can be automatically and intelligently adjusted in the video speed multiplication playing process, manual adjustment of the user is not needed, and the user experience is good.

Description

technical field [0001] The invention belongs to the technical field of double-speed video playback, and in particular relates to a voice-based double-speed video playback method and system.
