Abstract

The invention relates to a video scaling method and device, a server, a client and a storage medium. The scheme comprises the following steps: a server acquiring a to-be-processed video, wherein a video frame of the to-be-processed video comprises subtitle information; calculating subtitle proportion values of the subtitle information of the to-be-processed video in a plurality of preset directions; and sending the plurality of caption proportion values to the client; and the client performing scaling processing on the video frame of the to-be-processed video when the plurality of caption proportion values are all greater than or equal to a preset proportion threshold, and determining a target video frame. By applying the technical scheme provided by the embodiment of the invention, the problem that when the screen of the equipment is filled with the video frame, the video frame comprises all or part of caption information which is cut off, so that the video watching effect is poor issolved.

Description

technical field [0001] The present disclosure relates to the technical field of video processing, and in particular to a video scaling method, device, server, client and storage medium. Background technique [0002] Currently, when playing a video, in order to improve the immersion of video playback, the device scales the video frame proportionally so that the scaled video frame fills the screen of the device. [0003] However, the screens of different devices have different aspect ratios. The aspect ratio of the video frame is not necessarily equal to the aspect ratio of the screen. If the aspect ratio of the video frame is not equal to the aspect ratio of the screen, then when the video frame is scaled proportionally so that the zoomed video frame fills the screen of the device, the video frame must be cropped, and the cropped video frame occupies an area of ​​the video The proportion of the total frame area is as high as 17%. Based on this, if the video frame includes ...
