Disclosed are a video coding method and apparatus, a video decoding method and apparatus, an electronic device and a storage medium. The video coding method may include: acquiring a video picture, wherein the video picture is at least one frame of picture of a video; and performing weighted predictive coding of the video picture to generate a picture code stream, wherein the weighted predictive coding uses at least one set of weighted prediction identification information and parameters.

Video encoding method and apparatus, video decoding method and apparatus, and electronic device and storage medium

Provided are a picture encoding method, a picture encoding apparatus, a picture decoding method, a picture decoding apparatus, an electronic device and a storage medium. The encoding method includes: acquiring a video picture, and determining a picture feature of the video picture; determining in-loop identification information and out-loop identification information according to the picture feature; processing the video picture according to the in-loop identification information and the out-loop identification information; and encoding the processed video picture to generate a code stream, and writing the in-loop identification information and the out-loop identification information into the code stream. Therefore, the processing of a video picture is achieved both encoding and decoding out-loop and encoding and decoding in-loop according to the picture feature during a picture transmission process, thereby effectively improving the video encoding and decoding efficiency and improving the quality of a decoded picture at the same code rate.
