Video stream processing method and apparatus, computer device and storage medium

Abstract

The invention relates to a video stream processing method and apparatus. The method comprises the following steps: obtaining first audio stream data in live video stream data; performing voice recognition on the first audio stream data to obtain a voice recognition text; generating subtitle data comprising a subtitle text according to the voice recognition text; and adding the subtitle text to acorresponding image frame in the live video stream data according to time information to obtain processed live video stream data. By adoption of the scheme shown in the invention, in a live broadcastscene, the audio stream data in the live video stream data can be obtained, the voice recognition is performed on the audio stream data, the subtitle data are generated according to the recognition result, and the subtitle text in the subtitle data is added to the image frame of the corresponding subtitle text in the video stream according to the time information to obtain a live video stream containing the subtitle, in this way, accurate synchronization of the subtitle and the video image is achieved, meanwhile, as the subtitle data do not need to be manually inserted, the live broadcast delay can be effectively shortened.

Description

technical field [0001] The present application relates to the technical field of Internet applications, and in particular to a video stream processing method, device, computer equipment and storage 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). For example, please refer to figure 1 , which shows a schematic diagram of a live broadcast process provided by related technologies. Such as 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 li...
