Problems solved by technology
At present, the inter-frame prediction part of the main video coding standard needs to determine the corresponding interpolation filter based on the type of the selected motion vector after selecting the motion vector from the motion vector candidate list. This process is cumbersome and introduces unnecessary codec burden.

The invention discloses a video encoding and decoding method and device and a computer readable storage medium, and the method comprises the steps: obtaining a motion vector candidate list, and selecting a motion vector from the motion vector candidate list; determining a reference block of the current block according to the selected motion vector; and adopting a default interpolation filter to carry out pixel interpolation on the reference block. According to the video encoding and decoding method and device, and the computer readable storage medium, after the motion vector prediction value is determined from the motion vector prediction value candidate list and the reference block of the current block is determined based on the motion vector prediction value, the type of the interpolation filter is determined without tedious selection; instead, the default interpolation filter is directly adopted to carry out pixel interpolation on the reference block, so that the coding and decodingcomplexity can be reduced on the premise of not reducing the coding and decoding efficiency, and the hardware overhead is saved.
Description
technical field [0001] The present application generally relates to the technical field of video coding and decoding, and more specifically relates to a video coding and decoding method, device, and computer-readable storage medium. Background technique [0002] Prediction is an important module of the mainstream video coding framework, and prediction can include intra-frame prediction and inter-frame prediction. At present, the inter-frame prediction part of the main video coding standard needs to determine the corresponding interpolation filter based on the type of the selected motion vector after selecting the motion vector from the motion vector candidate list. This process is cumbersome and introduces unnecessary codec burden. . Contents of the invention [0003] The embodiment of the present application provides a video encoding and decoding solution, which can reduce encoding and decoding complexity and save hardware overhead. The following briefly describes the v...
