Abstract

The invention relates to a video shot segmentation method and device. The method comprises: under the condition that a transcoding instruction is detected, decoding a video, and obtaining a decoding result; determining a candidate frame in the decoding result; extracting the feature of each candidate frame; determining a first shot start frame of the video; for each candidate frame, calculating the distance between the candidate frame and the previous shot start frame of the candidate frame according to the characteristics of the candidate frame and the characteristics of the previous shot start frame of the candidate frame; and under the condition that the distance is greater than a threshold value, determining the candidate frame as a shot start frame. According to the method and the device, the shot segmentation can be carried out after decoding and before encoding in the transcoding process, so that independent decoding operation for the shot segmentation is not needed, and repeated decoding is avoided.

Description

technical field [0001] The present disclosure relates to the field of video technologies, and in particular, to a video shot segmentation method and device. Background technique [0002] In related technologies, a separate tool is used to segment video shots. First, the video needs to be decoded, and then the video is analyzed frame by frame to determine the shot segmentation points in the video. Since the video transcoding process also needs to be decoded, the video shot segmentation method in the related art causes repeated decoding operations. Contents of the invention [0003] In view of this, the present disclosure proposes a video shot segmentation method and device. [0004] According to an aspect of the present disclosure, a video shot segmentation method is provided, including: [0005] When a transcoding instruction is detected, the video is decoded to obtain a decoding result; [0006] determining candidate frames in said decoding results; [0007] extractin...
