Abstract
A method for picture decoding, a method for picture encoding, a decoder, and an encoder are provided. The method includes the following. A bitstream corresponding to a current picture is acquired. The bitstream is parsed to obtain a flag corresponding to the current picture. A cross-decoding function is disabled when a decoding manner indicated by the flag is independent decoding of colour components, where the cross-decoding function allows decoding based on a dependency relationship between two chroma components. The cross-decoding function is enabled when the decoding manner indicated by the flag is cross-decoding of colour components. The current picture is decoded in a direct mode (DM).
