Example Embodiment

[0035] In order to make the purpose, technical solutions and advantages of the present application, the present application will be described in further detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended to explain the present application and is not intended to limit the present application.

[0036] Based on FFMPEG, IOS Platform AVFoundation, iOS Platform VIDETOOLBOX, Android Platform MediaCodec, etc., you need to preset code rate parameters before video compression / transfer, to control video compression ratio. At this stage, most product platforms are preset rate parameters for video encoders using relative static classification strategies. Take the current video website as an example, the selection of the transcoding rate of the video on the background is based on the code rate, FPS (FPS PER Second, the number of frames per second), and the resolution is decisive. The rate ...

Abstract

The invention relates to a video compression method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a video to be compressed; performing inter-frame difference analysis on the image frames in the video to obtain inter-frame differences of the image frames; performing video dynamic analysis according to the inter-frame difference of each image frame to obtain a dynamic analysis result of the video; and determining a compression parameter according to the dynamic analysis result, and compressing the video based on the compression parameter. By adopting the method, the video compression effect can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a video compression method, device, computer equipment and storage medium. Background technique [0002] With the development of computer technology, multimedia resources on the Internet are more and more widely used in daily life, such as video and video resources in video websites, short video resources in social media, etc. Compared with text and image resources, the data volume of video is much larger. By compressing video to a certain extent, it can ensure the efficiency of video upload or download under different network conditions, and the smoothness of video playback. [0003] At present, when compressing video resources in the industry, compression parameters are set based on the platform's own compression processing capabilities to compress various videos, which may easily lead to low video compression or excessive video compression, affecting video clarity ...
