Performance fragment marking method, video playing method, video playing device, and video playing system

Abstract

The invention discloses a performance fragment marking method, a video playing method, a video playing device, and a video playing system, and belongs to the multimedia technology field. The performance fragment marking method comprises steps that a multimedia file corresponding to a role is acquired; according to the multimedia file, the characteristic of the role can be determined; a target video is decoded to acquire a data frame and a plating time stamp corresponding to the data frame; a target data frame matched with the characteristic of the role is identified in the data frame of the target video; according to the playing time stamp of the target data frame, performance fragment information corresponding to the role is marked automatically. According to the invention, a server can be used for the automatic marking of a plurality of target videos at the same time, and therefore problems of operation editors of low efficiency and poor accuracy caused by the fact that the operationeditors can only mark a small part of vides in a limited time period can be solved, and effect of marking the target video effectively in the limited time period can be achieved.

Description

technical field [0001] The embodiments of the present application relate to the field of multimedia technologies, and in particular to a method for labeling performance segments, a video playing method, device and system. Background technique [0002] According to the user's personal preferences or time-limited needs, the video playback APP (Application, application program) provides a function of only watching others. The function of only watching others refers to the function of watching only the performance clips of a certain character in the video. [0003] Since the operation editor can only manually mark the performance segment information of a part of the performance characters, the accuracy and efficiency of the marked performance segment information are poor. When a TV series is launched, it usually takes several days before the corresponding watch-only function can be provided. Contents of the invention [0004] The present application provides a tagging method...
