Abstract
A video encoding method includes: decoding a target coding unit to obtain a quantization coefficient matrix corresponding to the target coding unit; determining first reference information according to a quantization coefficient in the quantization coefficient matrix; obtaining a value of a target flag bit corresponding to the first reference information, the target flag bit being a flag bit of a target sub-block position, the target sub-block position being a position of a sub-block that requires processing of residual data in a coding unit; and determining the target sub-block position of the target coding unit according to the value of the target flag bit. A flag bit of a sub-block transform position or a transform skip sub-block position in a target coding unit is implicitly indicated using a quantization coefficient in a quantization coefficient matrix corresponding to a coding unit.
