Abstract

The invention discloses a method and system for processing a black edge of a vertical-screen video in an Android system, and the method comprises the following steps: S1, obtaining a cover picture corresponding to the vertical-screen video through an Android system network request method according to the cover picture address of the vertical-screen video; S2, carrying out the Gaussian Blur processing of the cover picture through an Gaussian curve algorithm, and obtaining a blurred picture; S3, calculating a video region of an updated view in the Android system and the black edge regions at the left and right sides of the video region, and calculating the regions at the left and right sides of the blurred picture; 4, respectively drawing the left and right regions of the blurred picture to the black edge regions at the left and right sides of the video region, enabling the central part of the video region to remain transparent, obtaining a blurred view, and enabling the blurred view to cover the vertical-screen video. The method improves the watching effect and experience for a user. The method achieves the drawing of a picture at a time, thereby reducing the memory occupied the picture, and improving the efficiency.

Description

technical field [0001] The invention relates to the technical field of Android system applications, in particular to a processing method and system for vertical screen video black borders on the Android system. Background technique [0002] Vertical screen video is generally a mobile phone vertical screen shot or live video, and the screen size ratio is generally 9:16. When playing on a TV, since the screen ratio of the TV is generally 16:9, there will be a large area on the left and right of the screen when displayed. Black borders affect the viewing effect and experience of users. [0003] Most of the current implementations are to cover a blurred picture on the black screen areas on both sides to achieve a mask effect. In this way, the left and right overlay mask images have poor image transition effects, and the memory usage of the two images is large. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a metho...
