Video data encoding method and device, computer equipment and storage medium

The invention relates to a video data encoding method and device, computer equipment and a storage medium. The method comprises the following steps that before the rate distortion cost of continuous division of the last sub-block (sub-coding unit) is calculated, an estimated value of a difference value between the rate distortion cost of non-division of the last sub-block and the optimal rate distortion cost of the last sub-block is calculated according to the existing rate distortion cost information, and then an estimated value of the optimal rate distortion cost of the last sub-block is obtained; an estimated value of the rate distortion cost of division of a father block (coding unit) is further obtained, and the estimated value is compared with an estimated value of the rate distortion cost of non-division of the father block to estimate and judge whether the father block chooses to be divided or not; if it is estimated and judged that the father block chooses not to be divided, the last sub-block skips
