A video coding code rate allocation and coding unit code rate allocation method, a computer equipment

摘要

CLAIMS What is claimed is: 1. A video coding bit rate allocation and code unit bit rate allocation method applied to a client terminal or server, comprising: obtaining a coded bit rate and a target bit rate of a current frame; Determining an uncoded bit rate, obtaining a predicted cost of a current code unit and an uncoded unit of a current code unit of the frame, which is determined based on precoding, calculating a cost ratio and an uncoded bit rate Determining a target bit rate of a current unit to be coded according to a ratio of a predicted cost of the current code unit of the frame and a predicted cost of the uncoded unit of the frame. The video coding bit rate allocation and code unit bit rate allocation method may further comprise estimating a predicted cost and uncoded unit of the current code unit of the frame that is closer to the actual cost as well as by the uncoded bit rate of the frame The target bit rate of the current unit to be coded by the ratio between the costs can be determined more accurately so that the present invention can reduce errors in bit rate allocation for the current unit to be coded and improve video quality.
