Abstract

The present application provides a video encoding, video decoding method and device, electronic equipment, and storage medium, wherein the video encoding method includes: acquiring a group of images to be encoded of a video to be encoded, and the group of images to be encoded includes a key frame to be encoded and a plurality of non-key frames to be encoded; determine a target encoding mode that matches the group of images to be encoded, and the target encoding mode is used to indicate two segments to be encoded that are divided into multiple non-key frames to be encoded Among them, all the non-key frames to be encoded in the first segment to be encoded refer to the key frames to be encoded, and the non-key frames to be encoded in the second segment to be encoded refer to each of the non-key frames to be encoded. At least one non-key frame before the key frame; encode the image group to be encoded according to the target encoding mode. The present application solves the problem of poor data transmission timeliness caused by excessive codec delay in video codec methods in the related art.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular, to a video encoding and video decoding method and device, electronic equipment, and a storage medium. Background technique [0002] Currently, for some video processing scenarios that require timeliness in data transmission, video can be encoded using low-latency encoding. For example, in VR encoding, the main view uses high-definition bit streams, and other views use low-definition bit streams. When the user turns the head, the code stream of other viewing angles needs to be switched to the high-definition code stream to avoid dizziness caused by the change of the picture definition in the viewing angle (switching from a high-definition picture to a low-definition picture) Discomfort reactions such as dizziness affect the user's visual experience. In order to quickly switch from low-definition video streams to high-definition video streams, VR encoding requi...
