Abstract

The present invention provides a method, device and terminal for adding subtitles to video. Specifically, first generate a number of transparent subtitle pictures named after the time range. For example, T1 and T2 represent two time points, and T1<=T2. The generated picture T1-T2.png indicates that in the time range from T1 to T2, the video The subtitles in the picture T1-T2.png will be displayed; then the video to which the subtitles will be added is decoded; the time stamp of the decoded video frame is compared with the time range of the subtitle picture; then the time range includes the time stamp of the video frame The subtitle picture is synthesized with the video frame to obtain the video frame with subtitles; the video with subtitles can be obtained by encoding the video frame with subtitles. Because the technical solution proposed by the present invention is concise, fast, and consumes less resources, it can meet the requirement of quickly adding subtitles to videos on a mobile terminal.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular to a video subtitle adding method, device and terminal. Background technique [0002] With the rapid development of the mobile Internet, various applications on mobile terminals have sprung up, among which video applications are basically necessary for every mobile terminal, and users can watch rich and colorful video materials by using video applications. [0003] Users sometimes need to edit the video while watching it. Some video application programs provide some basic video editing functions, including basic operations such as beautifying the video data, adding filters, and adding MVs. For some mobile terminal users, sometimes it is really necessary to add subtitles to the video, and the traditional method of adding subtitles using ffmpeg, due to too many libraries that need to be scheduled, it is difficult or even impossible to add subtitles to the video on...
