Multi-rate live video stream editing method and device, terminal and storage medium

Abstract

The embodiment of the invention relates to the technical field of information processing, and discloses a multi-rate live video stream editing method and device, a terminal and a storage medium. The method comprises the following steps: selecting a live video stream as a reference video stream, and determining a synchronous frame in the reference video stream; respectively acquiring frames corresponding to the synchronous frames in other live video streams except the reference video stream in the multi-rate live video streams; performing time axis synchronization on other live video streams and the reference video stream according to the acquired time difference between the frames corresponding to the synchronization frame and the synchronization frame; and editing the live video streams of each code rate according to the editing parameters of the reference video stream. Therefore, synchronous editing of the multi-code-rate video is realized, and the video editing efficiency is improved; besides, the edited short videos with different code rates can be obtained without carrying out secondary transcoding processing on the edited videos, so that the influence on the viewing quality of the edited short videos due to calculation errors in a transcoding process is avoided, and the viewing experience of a user is improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of information processing, and in particular to a multi-bit-rate live video stream editing method, device, terminal and storage medium. Background technique [0002] Live video is a live broadcast using the Internet and streaming media technology. Through real and vivid communication, it creates a strong sense of presence. It is an emerging social networking method. Mainly divided into real-time live broadcast of games, movies or TV series, introduction of product knowledge and sales of products, etc. Due to the long time of the live video, the attention of the audience is easily diverted, making it difficult to achieve the promotional effect of the video. In order for the viewers to accurately and directly grasp the key points of the video, it is necessary to edit the live video at this time, and quickly share the exciting parts of the live video with the audience, so as to improve th...

Problems solved by technology

[0003] The inventors found that there are at least the following problems in the related art: in the editing process of multi-bit-rate live video data, usually one of the bit-rate videos is edited, and then the generated short video is transcoded twice to obtain multiple different Bit rate edited short video
