摘要： 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.
