The invention provides a video encoding method and device, a video decoding method and device, electronic equipment and a storage medium, and the method comprises the steps: obtaining a to-be-encodedimage group of a to-be-encoded video, and enabling the to-be-encoded image group to comprise a to-be-encoded key frame and a plurality of to-be-encoded non-key frames; determining a target coding modematched with the to-be-coded image group, the target coding mode being used for indicating that a first to-be-coded non-key frame of each to-be-coded segment refers to a to-be-coded key frame in a plurality of to-be-coded segments into which a plurality of to-be-coded non-key frames are divided; wherein the other to-be-coded non-key frames except the first to-be-coded non-key frame refer to non-key frames in front of the other to-be-coded non-key frames in the same to-be-coded fragment; and encoding the to-be-encoded image group according to the target encoding mode. According to the method and the device, the problem of poor data transmission timeliness caused by overlarge encoding and decoding time delay in a video encoding and decoding mode in related technologies is solved.
Description
technical field [0001] The present application relates to the technical field of communications, and in particular to a video encoding and 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 streams of other viewing angles need to be switched to high-definition streams to avoid dizziness caused by changes in the definition of the picture 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 requires low-latency ...
