Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0036] Based on common video encoders such as FFMpeg, iOS platform AVFoundation, iOS platform VideoToolBox, and Android platform MediaCodec, it is necessary to preset bit rate parameters before video compression / transcoding to control the video compression ratio. At this stage, most product platforms use a relatively static classification strategy to preset bit rate parameters for video encoders. Taking the current major video websites as an example, the selection of the video transcoding rate in the background is based on the bit rate before uploading the video, FPS (Fram...

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 ...
