Embodiment Construction

[0021] In order to enable those skilled in the art to better understand the solutions of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0022] see figure 1 , showing a block diagram of the video playback architecture. Specifically, when the operating system obtains the data to be played, the next job is to analyze the audio and video data. A general video file consists of two parts: a video stream and an audio stream. Different video formats have different audio and video encapsulation formats. The process of synthesizing an audio stream and a video stream into a file is called a muxer, whereas the process of separating an audio stream and a video stream from a media file is called a demuxer. To play a video file, it is necessary to separate the audio stream and the video stream from the file stream, r...

Abstract

The application discloses a video processing method, device, electronic equipment and computer-readable medium, and relates to the technical field of video processing. The method includes: analyzing the video file to be played to obtain an audio stream and a video stream, the video file to be played is an online video; generating a subtitle stream according to the audio stream; synthesizing the subtitle stream and the video stream into a target video stream; displaying the target video stream on the screen. Therefore, when a user watches an online video without subtitles, the electronic device can automatically generate subtitles according to the audio stream of the video and display the subtitles on the interface playing the video, so that the user can obtain the video in a more real-time and accurate manner. content to improve user experience.
