Abstract

This application relates to a method and device for pushing subtitle data in a live broadcast scene. The method includes: acquiring video stream data and audio stream data, the audio stream data being data corresponding to the audio part in the video stream data; generating subtitle data according to the audio stream data, the subtitle data including subtitle text and time information; pushing the subtitle data To the user terminal, instruct the user terminal to synchronously display the subtitle text and the live video in the video stream data according to the time information corresponding to the subtitle text. Through the scheme shown in this application, for video stream data, subtitle data including subtitle text and time information can be generated according to the audio stream data corresponding to the video stream data, and then the subtitle data can be pushed to the user terminal, and the user terminal can generate the subtitle data according to the time information Synchronously display the subtitle text and the picture in the video stream data, so as to realize the accurate synchronization of the subtitle and the video picture.

Description

technical field [0001] The present application relates to the technical field of Internet applications, and in particular to a method for pushing subtitle data, a method for displaying subtitles, a device, a device, and a medium. Background technique [0002] With the continuous development of the mobile Internet, live video applications are becoming more and more widespread, and inserting subtitles into live video has become an important means to improve user viewing experience. [0003] In related technologies, subtitles in live video are usually inserted manually at a live recording end (such as a recording site / studio). refer to figure 1 , which shows a schematic diagram of a live broadcast process. like figure 1 As shown, in the process of collecting and encoding video images at the live recording end, the on-site staff manually inserts subtitle data, and the live recording end uploads the live video stream to the server through the live access service, and the serve...
