Abstract

The invention provides a detection method and device for scene switching points. The detection method comprises the steps that a first video is acquired; audio data in the first video are extracted to serve as first audio data; the switching position of scenes is determined according to the first audio data. By using the method, switching of the scenes in the video can be judged according to the specific audio information in the video, the complex work depending on workers for marking in the prior art is avoided, and the working efficiency for video processing is improved.

Description

technical field [0001] The invention relates to the technical field of digital multimedia, in particular to a method and device for detecting a scene switching point. Background technique [0002] With the rapid development of digital multimedia technology, more and more multimedia technologies are applied to people's work and life. [0003] In the field of video editing, the concept of "key frame" is often encountered. We can use related algorithms or tools to process all the key frames that exist in a certain video. For example, in a TV series, from 5 minutes 30 seconds to 10 minutes 15 seconds is a scene of talking in a coffee shop; from 10 minutes 16 seconds to 12 minutes 30 seconds is a scene of talking in a car. So a keyframe is included at 10 minutes and 16 seconds, which is exactly where a scene begins. And in subsequent conversations at this point in time, camera angles may be frequently switched, causing relevant algorithms or tools to judge many key frames, but ...
