Video coding method and device, video decoding method and device, electronic equipment and storage medium

The embodiment of the invention provides a video coding method and device, a video decoding method and device, electronic equipment and a storage medium, which are applied to the field of video processing, and the method comprises the following steps: obtaining a main transformation coefficient of a video to be coded; the main transform coefficient is obtained by performing discrete cosine transform on the video to be coded; calculating the relative deviation degree of the main transformation coefficient; the relative deviation degree represents the dispersion degree of the main transformation coefficient; and when the relative deviation degree is not less than a preset threshold value, skipping low-frequency inseparable transformation to carry out a subsequent coding process. By applying the video coding and decoding method and device, the electronic equipment and the storage medium provided by the embodiment of the invention, the complexity of video coding can be reduced. 本发明实施例提供了一种视频编码和解码方法、装置、电子设备及存储介质，应
