Abstract
A video coding includes: obtaining basic coding information and a basic quantization parameter corresponding to a current image in a video, and computing loss information of the current image based on the basic coding information; mapping the basic quantization parameter to obtain an initial enhanced quantization parameter; performing a bit rate computation using the initial enhanced quantization information to obtain an initial enhanced bit rate, and adjusting the initial enhanced quantization parameter when there is a difference between the initial enhanced bit rate and a preset target enhanced bit rate, to obtain a target enhanced quantization parameter; coding the loss information based on the target enhanced quantization parameter to obtain target enhanced coding information, and obtaining target coding information corresponding to the current image based on the basic coding information and the target enhanced coding information.
