Abstract

The embodiment of the invention discloses a video encoding and decoding method and device, electronic equipment and a storage medium. The video encoding method comprises the steps that at least one candidate list is obtained, and at least one candidate motion vector in the candidate list comprises rotation angle information; at least one candidate motion vector in the candidate list is selected asa reference motion vector, a motion vector difference value is determined according to the reference motion vector and a motion vector of a current prediction unit, and the motion vector difference value comprises angle difference value information; and encoding and / or transmitting the motion vector difference. According to the embodiment of the invention, the inter-frame prediction is carried out on the object rotation condition in the video frame image, and the prediction coding is carried out on the motion vector with the rotation angle information, so that the prediction, expression and efficient coding of the rotating motion object are realized, and the compression efficiency of the video data is further improved.

Description

technical field [0001] The present application relates to the technical field of multimedia processing, and in particular to a video encoding and decoding method, device, electronic equipment and storage medium. Background technique [0002] Video is a dynamic image sequence formed by connecting pictures one by one. If every pixel data of each picture is directly stored, the bandwidth occupied by the video code stream will be immeasurable. The function of video codec is to compress and digitally encode the image after the camera captures the image to obtain a more optimized code stream with strong anti-interference ability for transmission. In essence, it is to transmit high-quality video and audio data with the smallest possible bandwidth. A series of standards, from MPEG-1 to MPEG-2, from H.263, H.264 to H.265 (HEVC), and now H.266, are all aimed at optimizing the code stream, improving compression efficiency, Greater stability. [0003] Among them, the input of video e...
