Embodiment Construction

[0062] In order to make the purpose, technical solution and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0063] Before explaining the code rate allocation method provided in the embodiment of the present application in detail, the application scenario and implementation environment provided in the embodiment of the present application are firstly introduced.

[0064] First, the application scenarios involved in the embodiments of the present application are introduced.

[0065] At present, in the process of implementing video functions such as live video broadcast and video chat, the terminal involves the encoding operation of each frame of video image, and when encoding each frame of video image, it is necessary to assign a corresponding bit rate to each frame of video image .

[0066] In order to avoid large-scale mosaics in vide...

Abstract

The application discloses a code rate allocation method, device, terminal and storage medium, belonging to the technical field of terminals. The method includes: obtaining a target code rate required for encoding the current frame video picture; dividing the current frame video picture into multiple regions according to the region division requirements corresponding to the target code rate; The encoding priority of each area and the target code rate, and assign corresponding code rates to the multiple areas. The present application may divide the current video frame into multiple areas according to the area division requirements corresponding to the target code rate, and assign code rates to the multiple areas according to the coding priorities of the multiple areas. Since the divided area is related to the size of the target code rate, and the corresponding code rate needs to be assigned to each area according to the coding priority of each code rate, so as to ensure that each area can be allocated an appropriate code rate, and the code rate is improved. The situation of rate waste improves the flexibility of bit rate allocation.

Description

technical field [0001] The present application relates to the technical field of terminals, and in particular to a code rate allocation method, device, terminal and storage medium. Background technique [0002] With the development of the Internet and terminals, video services such as video chatting and live video broadcasting have been widely used, and the wide application of video services cannot be separated from the support of video coding technology. Among them, bit rate allocation is an important link in video coding technology. [0003] At present, in the process of video acquisition, it is usually necessary to encode each frame of video picture, and it is necessary to allocate a code rate for each frame of video picture during the encoding process. In order to avoid large-scale mosaics in the video screen, each frame of video screen can usually be divided into ROI (region of interest, region of interest) and non-ROI area, and according to a certain distribution rati...
