Problems solved by technology

The live broadcast is highly real-time and interactive, so the video stream cannot be post-processed. Among them, the lack of subtitles in the video stream will have a certain negative impact on the understanding of the viewers.
[0003] In related technologies, artificial recognition and subtitles lead to a long delay of live data, which cannot adapt to the high real-time nature of live broadcast

Embodiment Construction

[0022] Exemplary embodiments of the present application are described below in conjunction with the accompanying drawings, which include various details of the embodiments of the present application to facilitate understanding, and they should be regarded as exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

[0023] In order to reduce the delay in providing subtitle information for live video data, in this application, the subtitle information in the video stream is stored separately from the video stream, and there is no need to re-convert the video stream and subtitle information to generate a video.

[0024] in particular, figure 1 is a flowchart of a live video playb...

Abstract

The invention discloses a live streaming video playing method and device, and relates to the technical field of voice recognition, the technical field of video processing and the field of image processing. The specific implementation scheme is as follows: acquiring live streaming data, wherein live streaming comprises audio information and video stream information; identifying text information corresponding to the audio information, and generating subtitle information according to the text information; determining a start time point and an end time point corresponding to the subtitle information, and determining video frames corresponding to the start time point and the end time point in the video stream information; and storing the corresponding relationship between the subtitle information and the corresponding video frame in a preset database so as to play the live video according to the corresponding relationship. Therefore, on the basis of matching the subtitle information for thelive video stream, since the subtitle information and the video stream do not need to be mixed to generate new video data, the playing delay of the live video stream is reduced.

Description

technical field [0001] The present application relates to the technical fields of speech recognition, video processing and image processing, and in particular to a method and device for playing live video. Background technique [0002] Live streaming is widely used in press conferences, sports events, entertainment, etc. During the epidemic, it played an important role in education and sales. The live broadcast is highly real-time and interactive, so the video stream cannot be post-processed. Among them, the lack of subtitles in the video stream will have a certain negative impact on the understanding of the viewers. [0003] In related technologies, manual identification and subtitles are added, resulting in a long delay of live broadcast data, which cannot adapt to the high real-time nature of live broadcast. Contents of the invention [0004] The present application provides a live video playback method and device. On the basis of matching subtitle information for live...
