Abstract

The present application provides a method, device, device and medium for judging a skip coding mode based on video content. The method includes: determining the video source type of the video content based on the video content; based on the video source type, performing a co-located pixel relationship detection on the video frame of the video content and a reference video frame; sending the co-located pixel relationship to to the encoder to decide whether to use skip coding mode. The technical solution provided by the embodiment of the present application is based on the pre-analysis of the video content, and the analysis result is used as the reference information of the subsequent encoder, so that part of the video frame area can be quickly determined as the skip encoding mode, which saves encoding resources and improves encoding efficiency. , to a certain extent reduce the impact of imaging noise on encoding.

Description

technical field [0001] The present application relates to the technical field of video coding, and in particular to a method, device, device and medium for judging a skip coding mode based on video content. Background technique [0002] The skip coding mode is widely used in high-efficiency video coding standards such as H.264 and H.265. Coding mode prediction occupies a large proportion of the computing resources of the entire coding module. [0003] The inventors have found that image noise introduced by low- and medium-performance imaging devices for shooting videos will weaken the time correlation of areas with the same content in the video sequence and increase the bandwidth consumption of video coding. Contents of the invention [0004] In order to quickly determine some videos that may perform skip coding mode and reduce the coding bandwidth consumption caused by imaging noise, the embodiments of the present application intend to provide a method, device, device, a...
