Abstract

The invention discloses a video playing method, a video playing device, electronic equipment and a storage medium, and relates to the field of computer vision. The specific implementation scheme is as follows: receiving a material video sent by a server, wherein each frame in the material video comprises a first image part and a second image part; for each frame in the material video, performing image synthesis according to the transparency value carried by each first pixel point in the first image part and the color value carried by each second pixel point in the second image part to obtain a synthesized frame corresponding to each frame in the material video; and sequentially rendering and displaying the corresponding synthetic frames according to the sequence of each frame in the material video. Therefore, through adoption of the method, the resource volume can be greatly reduced, the GPU performance is improved, and the playing experience is improved.

Description

technical field [0001] The present application relates to the field of image processing, in particular to the field of computer vision, and in particular to a video playing method, a video playing device, electronic equipment and a storage medium. Background technique [0002] The video itself is composed of a set of encoded sequence frame pictures. The sequence frame picture needs to re-parse the picture every time the picture is played, which consumes a lot of GPU (Graphics Processing Unit, graphics processor) performance, and the sequence frame picture material resource volume is relatively large. [0003] Therefore, how to improve GPU performance and reduce resource size is an urgent problem to be solved. Contents of the invention [0004] The application provides a video playing method, a video playing device, electronic equipment and a storage medium. [0005] According to one aspect of the present application, a video playback method is provided, including: [00...
