Video coding method, computer device, and storage medium

A computer device, comprising memory and one or more processors, the memory storing computer readable instructions that, when executed by the one or more processors, enable the one or more processors to perform the following operations:

• obtaining, by the computer device, a current video frame to be coded, and obtaining a predicted residual of a reference video frame of the current video frame in a case that the current video frame is an inter prediction frame;
• determining, by the computer device, a quantization parameter threshold corresponding to the current video frame according to the predicted residual of the reference video frame;
• obtaining, by the computer device, a quantization parameter estimated value corresponding to the current video frame;
• selecting, by the computer device, a target coding mode from candidate coding modes according to the quantization parameter estimated value and the quantization parameter threshold, the candidate coding modes comprising a down-sampling mode and a full resolution mode;
• and
• coding, by the computer device, the current video frame according to the target coding mode.

A non-transitory computer readable storage medium storing a plurality of machine readable instructions in connection with a computer device having one or more processors, wherein the plurality of machine readable instructions, when executed by the one or more processors, cause the computer device to perform a plurality of operations including:
