Abstract

Embodiments of the present application provide a method and apparatus for generating a bullet screen file. The method includes: obtaining a target short video to be processed; Extracting first key frame information contained in the target short video, wherein the first key frame information comprises a detection key frame; obtaining a target reference key frame match with that detected key frame in a preset reference key frame database, and determining a target long video corresponding to the target reference key frame, wherein the preset reference key frame database comprises a reference keyframe extracted from the long video, and the reference key frame carries a time stamp; according to the timestamp of the target reference key frame, extracting the corresponding bullet screen information from the bullet screen file of the target long video; adding bullet screen information to the bullet screen file of the target short video. By adopting the invention, the interactivity of the short video can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for generating barrage files. Background technique [0002] In the fast-paced modern life, short videos can meet people's viewing needs in fragmented time, and become the main way for people to understand the world, record life, and entertain. [0003] Users often upload a large number of short videos to the Internet for other users to watch. In order to improve the viewing experience, a user can comment on the short video by posting a barrage while watching the short video, or interact with other users by liking an existing barrage or sending a new barrage. As an interactive function of short videos, barrage is an important factor to improve users' viewing experience and user stickiness of short videos. When there are many barrages, users are more willing to watch the short video. Bullet chat includes the user's thoughts on short video content, ...
