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, wherein the to-be-encoded image group comprises a to-be-encoded key frame and a plurality of to-be-encoded non-key frames; determining a target coding mode matching the to-be-coded image group, with the target coding mode being used for indicating that a to-be-coded non-key frame in a first to-be-coded segment refers to a to-be-coded key frame in a plurality of to-be-coded segments into which to-be-coded non-key frames are divided; wherein the to-be-coded non-key frames in the other to-be-coded fragments except the first to-be-coded fragment refer to the last non-key frame of at least one to-be-coded fragment before the other to-be-coded fragments; and encoding the to-be-encoded image group according to the target encoding mode. 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 communication technology field of this application, in particular, relates to a video encoding and decoding method and device, electronic equipment and storage medium.Background technique[0002]Currently, for some video processing scenes that require timeliness of data transmission, the video can be encoded using a low-delay encoding method. For example, in VR encoding, the main view uses a high-definition bit stream, and other views use a low-definition bit stream. When the user turns his head, the code streams of other viewing angles need to be switched to high-definition code streams to avoid the user's dizziness due to the change of the picture definition in the angle of view (switching from high-definition pictures to low-definition pictures) Discomfort such as dizziness affects the user's visual experience. In order to quickly switch from low-definition video stream to high-definition video stream, VR encoding needs to use low-latency encoding.[0003]The...
