Encoding Control Method and Apparatus, and Decoding Control Method and Apparatus

An encoding control method includes obtaining a current to-be-processed node in a target queue, where the target queue includes nodes whose corresponding space blocks are occupied in a constructed tree structure; obtaining a first mode identifier of the current to-be-processed node; and in a case that the first mode identifier is a first identifier, if nodes that have been processed continuously meet a first condition, performing multiway tree occupancy encoding on the current to-be-processed node; where the first condition includes that: a mode identifier of the node that has been processed continuously is the first identifier and a number of nodes that have been processed continuously is less than a first threshold.
