Abstract

The invention relates to a video coding method and device, a video decoding method and device, computer equipment and a storage medium. The method comprises the following steps of acquiring an input video sequence when video coding is carried out; acquiring a target video sequence coding mode corresponding to the input video sequence from a candidate video sequence coding mode, wherein the candidate video sequence coding mode comprises a constant resolution coding mode and a mixed resolution coding mode; and coding each input video frame of the input video sequence according to the target video sequence coding mode in order to obtain coded data. According to the method, the target video sequence coding mode of the input video sequence can be flexibly selected, the resolution of the input video sequence can be adaptively adjusted, and the video coding quality can be improved under a condition that the bandwidth is limited.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to video coding and decoding methods, devices, computer equipment and storage media. Background technique [0002] With the development of digital media technology and computer technology, video is used in various fields, such as mobile communication, network monitoring, network TV and so on. With the improvement of hardware performance and screen resolution, users' demand for high-definition video is increasingly strong. [0003] Under the condition of limited bandwidth, traditional encoders encode video frames indiscriminately, which may cause poor video quality in some scenes. For example, at 750kbps, when encoding all video frames indiscriminately, there are some In the case of poor video frame quality, it is analyzed that encoders such as H.264\H.265\iOS have similar problems. Contents of the invention [0004] Embodiments of the present invention provide a video ...
