The invention discloses a video encoding method and device, a video decoding method and device and a computer storage medium, and belongs to the technical field of information processing. According tothe application, syntactic elements are added into coded data, including a low-delay one-way prediction identifier used for indicating whether a reference image of an image only comprises the reference image of which the display sequence is before the image in the first reference image list or not. Therefore, subsequent decoding of the image is facilitated. The low-latency one-way prediction identifier is used for indicating that the reference image of the image only comprises the reference image of which the display sequence is located before the image in the first reference image list; only one image list needs to be obtained, the first reference image list and the second reference image list do not need to be obtained at the same time, and the complexity of the subsequent decoding process is reduced. 本申请公开了一种视
