Abstract

The application discloses a subtitle adding method and device, and belongs to the field of audio and video processing. The method comprises the following steps: acquiring a video source and a subtitlefile of the video source; slicing the video source to obtain a plurality of video fragments; acquiring subtitle fragments corresponding to the video fragments from the subtitle file respectively, wherein a subtitle fragment corresponding to at least one of the plurality of video fragments includes M subtitles, the duration of each of the m subtitles in the video source intersects with the duration of the corresponding video fragments in the video source, and m is a positive integer; and adding the acquired subtitle fragments into the corresponding video fragments respectively, and merging theplurality of video fragments added with the subtitle fragments to obtain a target video file. Through adoption of the subtitle addition method provided in the application, distributed subtitle addition can be realized, and the subtitle addition efficiency is increased.

Description

technical field [0001] The present application relates to the field of audio and video processing, in particular to a subtitle adding method and device. Background technique [0002] In order to improve the user's viewing experience, for a video source without subtitles, the video platform can add a subtitle file for the video source. After the subtitle file is added to the video source, processing such as distributed transcoding and image enhancement can also be performed on the video source to which the subtitle file is added. [0003] When the file size of the video source is large, it takes a long time to add subtitles to the video source, and the efficiency of adding subtitles is low, resulting in low processing efficiency of the entire video processing process. Contents of the invention [0004] The embodiments of the present application provide a method and device for adding subtitles, which can solve the problems of long time consumption and low efficiency of addi...
